Problems solved by technology

like figure 1 As shown, during its use, when the friction plate is worn, the pressure plate will move to the left, and the deformation λ of the diaphragm spring will decrease. figure 1 The curve of the curve shows that the working point b moves to the left, and the working pressing force increases, which causes the clutch torque capacity to change, making the engagement of the engine and the transmission system not very smooth; at the same time, the working point b moves to the left, making the separation force And the separation stroke also changes, which reduces the stability of the clutch operation, thus affecting the comfort of driving and riding, and the service life of the clutch will also be shortened

no. 1 approach

[0025] refer to image 3 , according to the first embodiment of the present invention, the compensation ring adjustment structure includes a tension spring 14 and an elastic lock plate 5, one end of the tension spring 14 is connected to the first compensation ring 12A, and the other end is connected to the second compensation ring 12B; The first end of the lock plate 5 is connected to the clutch cover 11 , and the second end is connected to the second compensating ring 12B.

[0026]Both ends of the extension spring 14 are respectively connected to the first and second compensating rings 12A and 12B, and the connection methods can be realized by various connection methods, such as welding, riveting, screwing, clamping and so on. But preferably, grooves 20A and 20B are respectively provided on the first and second compensating rings 12A and 12B, and then the two ends of the extension spring 14 are respectively hooked in the grooves 20A and 20B. This connection method has the adv...

no. 2 approach

[0035] refer to Figure 4 , according to the second embodiment of the present invention, the compensation ring adjustment structure includes a tension spring 14, an elastic lock plate 5, an adjustment column 6 and a first spring 3, wherein one end of the tension spring 14 is connected to the first compensation ring 12A, and the other end Connect the second compensation ring 12B; the first end of the elastic lock plate 5 is directly connected to the adjustment column 6, and the second end is connected to the second compensation ring 12B; one end of the adjustment column passes through the through hole on the clutch cover 11, and then connects with a limit The block 11 is welded together, so that the adjustment column 6 can rotate around its axis, and the elastic lock plate can also rotate; the second end of the adjustment column passes through the through hole formed on the pressure plate 13 and has a flange at the end; The first spring 3 is compressed between the flange and th...

no. 3 approach

[0043] refer to Figure 5 , in addition, according to the third embodiment of the present invention, a limit post 9 along the clutch circumferential direction can also be set between the adjustment post 6 and the compensation rings 12A and 12B, and the left end of the stop post 9 is inserted into the pressure plate In the hole formed in 13, the right end is inserted into the square hole in the middle part of the elastic lock plate 5, and between the right side of the pressure plate 13 and the elastic lock plate 5, there is a second spring 8 sleeved on the limit post 9 , to support the elastic lock plate 5.

[0044]Through this embodiment, the adjustment column 6 and the elastic lock plate 5 are kept in balance by the joint action of the first spring 3 and the second spring 8, and the movement of the elastic lock plate 5 around the adjustment column 6 can also be limited by the function of the limit post 9. The rotation angle further optimizes the technical solution of the pre...

Abstract

The inventive clutch comprises a flywheel, a clutch case, a pressure disk, a driven disk assembly and a diaphragm spring and also includes an automatic compensating structure. The automatic compensating structure includes first and second compensated loops and a compensated-loop adjusting structure for making the first and second compensated loops rotate relatively. The first and second compensated loops locate between the diaphragm and the pressure disk and contact each other. When the friction plate takes the wear, using the relative rotation between the first and second compensated loops makes compensation the gap caused by the wearing of the friction plate, so as to make the working position of the diaphragm spring not change and make the torque volume of the clutch keep stable.

Description

technical field [0001] The invention relates to an automobile clutch, in particular to a diaphragm spring clutch. Background technique [0002] In the automotive mechanical transmission system powered by an internal combustion engine, the clutch is generally arranged between the engine and the transmission to cut off or engage the transmission of power. Its main functions are: to smoothly connect the engine and the drive train when starting, so that the car can start smoothly; when shifting gears, quickly and completely separate the engine from the drive train to reduce the impact between the gears in the transmission for easy shifting; During the working process, when the load is too heavy, the clutch slips to protect the transmission system and prevent parts from being damaged due to overload; at the same time, it can effectively reduce the vibration and noise in the transmission system. [0003] Obviously, the clutch occupies an important position in the power plant of t...
