Embodiment:
Embodiment one:
A kind of automobile clutch of automatic friction compensation pad wear, comprise friction plate 1, platen 2, diaphragm spring 11, clutch cover 9 and automatic friction compensation pad wear mechanism, described automatic friction compensation pad wear mechanism is by the downward modulation domain 4, raise the domain 5, compensating plate 8, keep reed 7, downward modulation domain effect spring 3, compensating plate effect spring 10, inceptive positioning device 6 is formed, one annular groove Q is arranged on the platen 2, its annulus width is formed than the smaller ring bodies of annular groove Q width with the bottom of raising the domain 5 by being threaded in the top of the downward modulation domain 4, and be contained between the annular groove Q and diaphragm spring 11 of platen, annular groove Q bottom is withstood in the lower end of the downward modulation domain 4; The upper end of raising the domain 5 leans diaphragm spring 11 times; Keeping an end of reed 7 is that fixed end is fixed on the platen 2 by set screw 13, and the other end is that free end passes the top that the locating slot O that raises the domain is pressed against inceptive positioning device 6; Bottom with inceptive positioning device 6 of two right angle bending shapes is fixedly mounted on the clutch cover 9; Between the free end of arc groove P on the platen 2 and maintenance reed 7, the compensating plate 8 (referring to Fig. 1, Fig. 2) that a circumferential section height in edge changes is installed.
Embodiment two:
A kind of automobile clutch of automatic friction compensation pad wear, its basic structure is with embodiment one, institute's difference is: in the described automatic friction compensation pad wear mechanism, the lower end surface of the upper-end surface of the downward modulation domain 4, the rise domain 5 is respectively the flexuose inclined-plane, (referring to Fig. 4), the flexuose inclined-plane of upper and lower adjustment ring by end face cooperatively interacts and forms a ring bodies, and the annular groove bottom is withstood in the lower end of the downward modulation domain; The upper end of raising the domain leans under diaphragm spring (referring to Fig. 1, Fig. 3).During work, the downward modulation domain 4 relies on the flexuose inclined-plane to make when circumferentially rotating to raise the domain 5 move right vertically (leaving motor).
Working principle and working procedure:
With embodiment one is example, after friction plate 1 attrition value reaches λ, platen 2 is moved to the left λ value (promptly near motor) vertically, newly-increased gap lambda value between platen 2 and maintenance reed free end, the arc groove P of compensating plate 8 on compensating plate effect spring 10 effect lower edge platens 2 moves, and relies on along the compensating for variations gap lambda value of circumferential section height; When clutch separation, diaphragm spring 11 outer ends move right (promptly leaving motor) leave and raise the domain 5, being applied to the impacting force that raises on the domain 5 eliminates, the downward modulation domain 4 rotates at the effect lower edge circumference of downward modulation domain effect spring 3, and raise between the domain 5 and the downward modulation domain 4 is to be threaded, and raise on the domain 5 circumferential locating slot O is arranged, the free end that is held reed 7 blocks, can not rotate, therefore, raise the domain 5 λ value (promptly leaving motor) that moves right vertically, remedy friction disc wear amount λ value, the outer end of diaphragm spring 11 when finishing, clutch separation is pressed against on the rise domain 5 in former axial position again, compensation process is finished, and diaphragm spring 11 returns to axial position and the state before friction plate 1 wearing and tearing, and the C value is constant, the property retention that makes clutch transmission torque guarantees that in former design point automobile clutch in use can not cause the diaphragm spring impacting force to change because of the wearing and tearing of friction plate.
For embodiment's two described structures, its working principle and working procedure are similar, and difference is: during work, rely on the flexuose inclined-plane that the rise domain 5 is moved right when reducing the domain 4 along circumferential the rotation.
