Peugeot car automatic transmission troubleshooting instances

Fault symptom: automatic transmission slipping, under the car. This car in running of the first automatic transmission slip, and then the car under the smoke, then cannot travel. Troubleshooting: First survey of automatic transmission oil cooler oil level, when the liquid level higher than the maximum around 1.5cm, the oil is dirty, a transmission oil burning after the characteristic odor. Further test operation, heating and automatic transmission oil, so that the observed after heating automatic transmission oil can rise to the level of what. Test operation of Italian (Forum Gallery) found outside the upshift is quite smooth, from1rise to 2gear, from2rise to 3files, can be the normal shift, but entered the4 gear, the acceleration of the engine, automatic transmission will start to slip. Put the gear selector lever is placed on the 3position, the3gear to return to a normal state. R stalls are normal. Do stall test, either forward or backward, the engine stall speed is2100r/min, is normal. Raise are the vehicle up to slip ring investigate, in an automatic transmission and engine between the area, the subframe and the power steering pump leakage of many in the area of automatic transmission oil. Smoking cause, perhaps is the automatic transmission oil leak onto the exhaust pipe. Steam cleaning, in order to confirm the oil spill, lifting up his car, put the gear selection lever in the D position, to run continuously for 20minutes, not found in automatic transmission oil. Remove automatic transmission oil pan at the oil pan, there is too much grinding powder clutch. This forced decomposition of automatic transmission. The automatic transmission from the car downs, then the decomposition operations. First remove the E clutch, the brake drum parts have been heat discoloration, friction plate grinding burn, steel exposed. Because of the heat, the piston seal hardening. The rest of the A, B, C, C ', D each clutch, internal are not particularly unusual. This4 gear slip causes have been clarified, but why the E clutch is not good? Put all the parts disassemble cleaning. The valve body is electronically controlled, but the three stacking of a very complex body. But the body, operating smoothly, but also found no other abnormalities. All the valve core movement smoothness,10throttle position, the aperture and the installation directions and information in line with the normal, spring. Cover almost by ordinary tools can decompose. But the fixed roller bearing outer ring nut, must use special tool removal. The nut is used to produce their own tools to ring slip remove. Without the use of special tools, and the use of universal joint wrench, screwdriver and hammer head can be removed, but the nut to be injured. While the installation must be used 5ON m torque into tight. So there must be special tools. Manufacture of special tools can use abandoned roller bearing outer ring, wheel and small grinding machine processing into one clutch shape, and then take a socket interface of the driving rod is cut by half, and then welding welding it. The nut, and in diameter, thinner thickness, tightness of the nut, stressing points in its radius extension line. Go back to slip rings the starting point, along the E clutch pressure oil supply channel under investigation. Results show that pressure oil is pumped from the interior of the hood of the hole. Through the turbine shaft hole and enter the E clutch piston side. Turbine shaft hole and the embedded with a steel ring, a seal, as if the engine piston ring. The steel ring to moderate degree of tightness and the pump casing inside diameter contact, the inner diameter of the pump of this part of pressing a bronze sleeve. Steel ring and the inner sleeve contact portions are in a circular wear. Hands touch, obviously wear a stage, forming a groove, which is probably the E clutch wear.

Mechanical seal

High temperature slip ring , high speed rotary joints, homemade rotary joint, rotary joint, rotary joint manufacturers, Guangdong rotary joint, rotary joint, rotary joint Fujian, Jiangxi, Hunan, Sichuan rotary joint rotary joint, rotary joint, rotary joint of Zhejiang Jiangsu. Mechanical Seal (mechanical seal) is defined by at least one rotation axis perpendicular to the face of the fluid pressure and elastic compensating mechanism (or magnetic) role and auxiliary sealed to keep fit relative sliding and composed of the device to prevent fluid leakage. Elastic loading mechanism and the secondary seal are a metallic tube mechanical seal pattern we call metal bellows seal. In the light of sealing, and use of rubber bellows as auxiliary seal, rubber bellows elastic finite, generally need to ring slip be supplemented by a spring to meet the loading force. " Mechanical seals" are often referred to as "the machine seal". Mechanical seal components: Mainly in the following four parts. A. major components: a dynamic ring and a static ring. B. Auxiliary seal: the seal (O shape, X, U, wedge, rectangular flexible graphite, PTFE coated rubber O ring). C. Elastic compensation mechanism: slip rings , a push ring. D. Transmission parts: elastic skip seat and a key or a variety of screws.

Why is called H type rotary joint

H type slip ring name comes from the first letters of the alloy. Rotary joint structure is composed of copper, aluminum and other elements, so called alloy. The shell is made from brass consists of many, is also useful for aluminum, carbon steel. The hollow shaft is usually adopts304 stainless steel materials and processing. H type ring slip system specifically for the cooling of product design, it has the advantages of small volume, light weight, low friction torque, using a balanced type sealing, friction of materials according to the medium environment, choose a variety of impregnated graphite, bronze, tungsten carbide, silicon nitride on different group, enough to resist rust, dirt, debris and other impurity on the sealing surface. Apply with water, air and other medium device at high speed; maximum speed:1000RPM; maximum pressure: 1.8Mpa. Ordinary type maximum temperature:100; high temperature slip rings maximum temperature180. The balancing type sealing structure, the sealing ring generated at the ends of the pressure is almost equal, thereby effectively reducing the sealing load on the wear of the sealing surface, fast speed, strong stability, prolong the service life. Mainly used for paper making, textile, metallurgical industries of the cooling system

Rotary transformer in rotor position measurement

Introduction In military vehicle AC drive system, due to slip rings shock and vibration and the change of temperature and humidity and other harsh working environment, ordinary detection of rotor position encoder is easy to damage, and the rotary transformer due to its durability and high reliability, it can solve this problem. But a rotary transformer is a simulation of mechanical and electrical components, can not meet the requirements of digital, so it is necessary to realize the interface circuit of analog signal and control system digital signal conversion between, this kind of interface circuit is a kind of special mold / number converter, is what we often say that the resolver / digital converter ( RDC ). RDC circuit design The main device and principle This system uses the Tamagawa Japan produced TS262N21E11brushless resolver. Main circuit adopts the ADI two R/D converter AD2S90and programmable oscillator AD2S99, two to use. AD2S90RDC circuit is the core design. Internal function modules is mainly composed of a phase sensitive detector, a multiplier, a voltage-controlled oscillator VCO), an up-down counter to slipring form a closed loop feedback system. When the rotary transformer two stator winding output signals Esinwtsinq and Esinwtcosq were sent to AD2S90sin and COS input pin, through its internal operational sent to the multiplier, at this time, if the internal or the counter output initial digital angle J is fed to a multiplier, the multiplication is obtained after the output signal is Esinwtcosqsinj and Esinwtsinqcosj, two and then subtract operation will be the output signal Esinwtsin ( q-j ), the errors in the signals section is fed by a phase sensitive detector, a multiplier, a voltage controlled oscillator, an up-down counter to form a closed loop feedback system, so that the sin ( q-j ) =0, q-j=0, when the up-down counter output digital angle J is the rotor displacement angle. AD2S99 is designed for resolver-digital converter provides excitation signal source, signal frequency has 4 choices, namely 2kHz,5kHz,10kHz and 20kHz. It not only provides for AD2S90synchronous reference voltage signal, at the same time also rotating transformer to provide high quality sine wave excitation signal, also has a signal phase compensation and signal loss detection etc.. RDC circuit design Rotary joint transformer two winding output signals SINJ and chose as AD2S90angular position detection of the analog signal input, through a shielded twisted pair, respectively, received AD2S90 corresponding to the input SIN and SINL0. At the same time, COS and COSL0signal as feedback signals are connected to the AD2S99, through the AD2S99the internal processing to produce an output signal ( SYNREF± 3Vp-p square wave output signal and the phase and the SIN and COS input signals to maintain consistent ), connected to AD2S90REF pins, to compensate for the rotary transformer side to the two side of the phase deviation RDC, otherwise it will reduce the accuracy of conversion.

Rotary joint development review and future trend

ring slip for a lot of people belonging to the strange word, in Taiwan and abroad and is called the" pressure rotary joint" or" rotary joint". It is connected with an outer pipeline equipment dryer must be used. Involving more than 20 industries, which belong to the cross industry most one of the products. However, it is only in recent decades have, in the country's history of only thirty years time. Early people used sealing tape (or nylon rope) wrapped around the rotary shaft, rely on the hard friction and extrusion to prevent drying cylinder within the circulation medium leakage. Advantages of cheap material, easy to find. The disadvantage of using life is too short, long, but ten or twenty days, only three five days short of. Not only are the maintainer repair times increasing, more important is the device to pause frequently, so that the production cannot be normal. In foreign countries, from the beginning of this century the use of a rotary joint, which seals are metal, also with graphite, and rubber, for the pursuit of life, the number is set to several sealing, the circulation medium in a seal leak, and another sealing device. So that the service life of the product can be up to ten years. However, due to manufacturing structure closely, more repair complex, which brings a lot of inconvenience. One is the professional factory, machine, rotating joint understanding for less. Rotating joint in terms of equipment accounted for the proportion of small, for such a complex structure, the long appears to be at a loss what to do; two, with high technical content, accessories and not universal, and even their own people are unable to buy the right accessories, leakage and damage only when the waste treatment; three, product value is low, profit thin, services provide after sale service. At present, the aggravation of the market competition, foreign suppliers are supplied to large machinery factory, with a number of big have certain profit. While the use of the factory to repair to the original purchase accessories must be. One can imagine the mail fee. The most complex rotary joints, should belong to Germany. In the overall design of rotary joint spend a lot of thoughts. The most sophisticated rotary joint should belong to Japan. The same types of rotary joints than domestic production to small half, even smaller. Sealing material thin but durable. While other countries are much the same. Domestic manufacturers are innumerable, blossom everywhere, but canbe " under the kitchen, the hall is scanty." ". Is to compete on price, no long-term development thought. Willing to spend money on research and development of new products of the enterprises is too small, and too much imitation and workshop processing. The ability and technology enterprises are reluctant to delve into new areas. However, with the development of society, the increasing of large enterprises and export needs, forcing manufacturers to make efforts in quality, product appearance and endoparasitic take care of, otherwise, only waiting to be eliminated. At present, some enterprises have begun to introduce foreign technology and foreign parts, to fill the domestic blank. In product quality has certain promotion. Well, he said! Said there are more suspicious advertising!

Slip ring mechanical principle and how in the design of accurate selection

In the modern society, more and more machinery industry, however for mechanical design engineers, the most painful is the mechanical structure selection, only in the understanding of the slip ring mechanical principle, to choosing, in order to avoid the worst work, by the Shenzhen City Chia Chi electrical and mechanical technology limited company professionals for everyone description of slip ring mechanical principle and how in the design of accurate selection For mechanical design engineers, the most painful is the mechanical structure selection, only in the understanding of the slip ring mechanical principle, to choosing, so how to make correct and reasonable slip ring parts selection, we first from the slip ring matching principle, with the role of the slip ring is stationary ring and ring rotating ring are respectively connected with the installing position of the static part (usually a ring seat ) and a rotary part (usually the shaft ) are combined together, thereby realizing in rotating state transferring load and limited movement relative to a stationary position system the basic task of the system. The slip ring is machinery of the important parts, also can say is mechanical joints, and we human beings without joints, it is not, if it were not for the joint than a paralyzed, and what role? It is useless, machinery is the same, no slip ring, machinery is used up, so the machine is inseparable from the slip ring, left the ring could not live, is tantamount to a waste. The use of rotary slip ring of various mechanical devices, instruments and other market performance requirement is strict with each passing day, the slip ring the required conditions, properties are becoming more and more diverse. In order forfor a large number of structures, size, choose the most suitable for the needs of the slip ring, from a variety of perspectives on. In the choice of slip rings , in general, considered as a shaft ring arrangement, installation, disassembly difficult, slip ring allows space, size and slip ring market, generally decided slip ring structure. Slip ring using the method is complicated, some rotary slip ring is matched, the general technical staff knows knowledge, our common people certainly do not know, we now introduce for everybody the slip ring rotates with the use and requirement, also to you later with slip-ring now management foundation. On the shaft and the slip ring seat, rotary slip ring in radial, axial and tangential directions three directions to fix the position. The radial and tangential position through the slip ring ring is tightly matched with the axial positioning of mining. Only in a few cases the tight fit; generally the axial limit parts, such as the end cap and the retainer ring will be defined in the clearance of the axial position range. Secondly, while a comparative study of the use of slip ring of a variety of mechanical design life and slip rings of different durability limit, side slip ring size decision. In the choice of slip ring, often tends to consider only the slip ring fatigue life, the grease caused by aging grease life, wear, noise and so on also need to study. Moreover, according to different purposes, it is necessary to select the precision, clearance, retainer structure, grease and so on demand, a special design of the slip ring. The fixed side slip ring, just choose the available surface of rotation in the axial direction (such as via slip ring) or to assembly surface moves (such as ball ring slip ring). In a relatively short shaft, the fixed side and free side no other case, using only one-way fixed axially movable ring (such as electrical slip ring). However, choice of slip ring and there is no certain order, rule, the priority should be considered on the slip ring is the required conditions, performance, the most connected matters, very practical. Usually, the shaft is two rings in the radial and axial support, at this time, the side of the slip ring called the fixed side slip ring, which bears the radial and axial two load, fixed shaft and slip ring box between the relative axial displacement of role. The other side is called the free side, only to bear radial load, axial can move relative, so as to solve the caused by temperature change shaft extension problems and mounting ring spacing error. Only the selection is certain circumstances, can quickly complete mechanical structure design task. So in the design, we try to know more about the slip ring type matters needing attention.

The conductive ring product core factors of production process control

As a conductive slip ring of high precision products and many mechanical components, the final product competition, in the final analysis is the process of competition, in the production process, the conductive ring production and processing has a lot of attention, last article we mainly talk about the slip ring single production and production the difference as well as the impact on cost, here Shenzhen City Jia Chi electrical science and technology limited company and we work together to talk about the slip rings in the production process with special attention to matters. Precision machining parts, the necessary production equipment is a must, if no tool as security, high-quality conductive slip ring cannot be guaranteed. In the use of NC lathe processing conditions, the numerical control machine tool has not achieved widespread use conditions, generally should be put on the back of too much margin, especially with forging, casting hard crust layer cushion placed in ordinary lathe. If it is necessary to use numerical control lathe, it should pay attention to the program's flexible arrangement. Slip ring as a precision parts, the production process requirement is very strict, especially high number of rings, multiple, small volume of miniature conductive slip ring, because this kind of slip ring has the advantages of small volume, channel spacing between the internal structure is not big also, but, with great precision, little error may cause the whole parts scrapped, in the normal production process, the training of staff to throughout the production process, the most important thing is not the assets of enterprises, is the person, need people to ensure product quality. People and companies need to build a relationship of mutual trust, only in this way, in the staff to achieve maximum benefit at the same time, the way to achieve the company's goals and ideals. The hydraulic chuck and a hydraulic clamping cylinder are connected by rod to achieve, in hardware facilities, microscopy and enough bright light is essential, in the installation and manual inspection process, microscopy as a first line of control process, should be configured on every desk, all installation and examination must be performed under a microscope, especially micro ring, eye for some internal structure although tell, but as a result of working time is long, will produce giddiness and other factors led to the internal structure of the installation and inspection quality, thereby affecting the entire batch of slip ring overall quality, this regarding Serip, is also not permitted. When it comes to light, is not a simple light bulb, need not heating led environmental protection lamp is the best, at work, not on human harm, the human eye can not be so tired easily, thereby ensuring that the whole conductive slip ring products will not cause defects such as repair problem. Only to ensure that the production process and flow, in the scientific management and guide below, orderly production and processing, to strengthen the quality of staff and a sense of responsibility, can effectively control the process and product quality control.
