1、 外文资料翻译 Automobile Clutch Nowadays the pioneers of the clutch disc, clutch disc is more pieces of it until 1925 later. The multi-gear clutch main advantage is that car started the clutch engagement is no impact on the smooth. Early in the design, layout design, according to slice pairs of a steel pl

2、ate with a bronze blanks. Using the friction pair of pure metal, put them in oil, can achieve more satisfactory performance. As the power to combustion in mechanical transmission automobiles, clutch is as an independent assembly. The clutch is usually served in the engine and transmission, the activ

3、e part between connected with engine flywheel, driven and transmission. Various types of cars for widespread adoption of friction clutch, in fact, is a kind of depend on their part, driven to relay the friction between the power and the separation. The major function of the clutch is cut off and the

4、 realization of the engine and transmission, to ensure smooth, stable car When the shift in the engine and transmission of separation, reduce transmission gear shift between the impact, Work in the dynamic load is larger, can limit the transmission of maximum torque, in order to prevent the transmis

5、sion parts of a damaged by overload, Reducing effectively the transmission of the vibration and noise. In the early development of clutch structures, the most successful conical clutch. It was the prototype design in 1889 German Daimler company production of steel wheel on the car. It is to make the

6、 engine flywheel hole taper as clutch active. The taper clutch scheme continues to the middle of the twentieth century, when the manufacture, cone-shaped clutch friction relatively simple, easy to repair. It was used LuoMao friction material, leather belt, etc. Then have been hoof - drum clutch, its

7、 structure in the solid-bowl clingy reaches hoof. Hoof - drum clutch friction components with wood, leather belt is such, shoe - drum clutch weight is light cone clutch. Whatever tapered clutch or hoof - drum clutch, easy to cause the separation is not complete appear even Lord, follower cannot sepa

8、rate self-locking phenomenon. Years of practical experience and technical improvement makes people tend to preferred dry friction clutch single chip, because it has driven part of inertia, good heat, simple structure, convenient adjustment, compact size, etc, but also because completely in structure

9、, already can take action to smooth, so now junction disc is widely used in large, medium and small various models. Now monolithic dry type clutch in structural design is quite perfect. Using the axial elastic platen, improve the clutch of comfort. The clutch platen assembly installed in reverse, pr

10、event the transmission system of shock of torsional resonances, reduced the transmission system of noise and load. As the car comfort requirements, clutch in original basis has been obtained by car, by continuously improved by increasing the quality of the flywheel has double shock absorber, can tur

11、n better reduce transmission noise. Due to heavy clutch, commercial, engine power tends to large-scale increasing, but the size of the space increased clutch allows the use of limited, clutch, cool 1, increase conditions to improve ability, preaching clutch torsion life-span, simplify the operation

12、has become the development trend of the heavy clutch. In order to improve the ability of torsion, in heavy vehicles can be used on double dry type clutch. Theoretically, in the same radial dimensions, biplate clutch torsion ability and the service life is 2 times of single chip. But other objective

13、factors, the actual effects of low value than others. In recent years, the wet clutch on technology improvement, some heavy cart in abroad and start using multiple wet clutch. Compared with dry type clutch, due to the use of the pump are forced cooling, friction surface temperature is lower than 93

14、degrees Celsius (not), therefore, long time also does not start sliding friction loss. Refer to the information at home and abroad were told that this clutch can use dry type clutch of 5-6 times, but the advantages of the wet clutch play must be in a temperature range, more than it can achieve a tem

15、perature range will play a negative effects. Now this technology is not perfect. The flywheel is a major part of the clutch . The flywheel mounts to the engines crankshaft and transmits engine torque to the clutch assembly . The flywheel , when coupled with the clutch disc and pressure plate makes a

16、nd breaks the flow of power the engine to the transmission . The flywheel provides a mounting location for the clutch assembly as well . When the clutch is applied , the flywheel transfers engine torque to the clutch disc . Because of its weight , the flywheel helps to smooth engine operation . The

17、flywheel also has a large ring gear at its outer edge , which engages with a pinion gear on the starter motor during engine cranking . The clutch disc fits between the flywheel and the pressure plate . The clutch disc has a splined hub that fits over splines on the transmission input shaft . A splin

18、ed hub has grooves that match splines on the shaft . These splines fit in the grooves .Thus , the two parts held together . However , back and forth movement of the disc on the shaft is possible . Attached to the input shaft , the disc turns at the speed of the shaft . The clutch pressure plate is g

19、enerally made of cast iron . It is round and about the same diameter as the clutch disc . One side of the pressure plate is machined smooth . This side will press the clutch disc facing are against the flywheel . The outer side has shapes to facilitate attachment of spring and release mechanism . The two primary types of pressure plate assemblies are coil spring assembly and diaphragm spring .
