Two support rings can relatively rotate.
The working principle of the utility model are as follows:
The utility model is a part of vehicle friction clutch, transmits engine drive power to speed change by flywheel
Case need to cut off power when needing to carry out speed change, remaining time then guarantees that power transmits.As shown in Figure 1, it is in the prior art from
Clutch cap assemblies are equipped with clutch cover board 3, diaphragm spring 7 and platen 5, during clutch operating, clutch pedal stress
Press 7 central part of diaphragm spring radially-inwardly, and 7 outer rim of diaphragm spring is due to the point action of support rivet 1
It lifts, and then is lifted by 2 zone of action dynamic pressure disk 5 of connection sheet, 5 disconnecting clutch driven disc of platen makes the driving from engine
The transmitting of power is interrupted,
And when utility model works, when transmitting driving force, platen 5 compresses clutch driven plate, makes clutch driven plate
Friction plate is contacted with flywheel, at this time as shown in figure 3, the first support ring 11 and the second support ring 12 in device of wear compensation 9
Between 5 outer rim of platen and diaphragm spring edge 7a, and the cambered top end of the first support ring 11 supports diaphragm spring edge 7a, when
After let slip the clutch, the elastic portion 7b among diaphragm spring 7 is released bearing pressing, and diaphragm spring edge 7a is with fulcrum ring
4 lift for fulcrum, while platen 5 and support ring assemblies being driven to lift together, make clutch driven plate separation cut power, at this time
As shown in Fig. 8~9, since there are one between 13 bottom wall of limited mouth in the retention bead 14 on limiter 13 and support ring assemblies
Fixed spacing, the spacing realize the lift action of support ring assemblies enough, and 13 pairs of support ring assemblies of limiter and platen 5 will not be made to move
It is dynamic to cause obstacle, the stress of clutch pedal is released after completing speed change, diaphragm spring 7 sets back, while driving 5 He of platen
Support ring assemblies set back together, and clutch driven plate is depressed on flywheel at once to be continued to transmit power.
On the other hand, since long-time is using can make platen 5 or clutch driven plate friction plate wear, 5 meeting of platen
It relatively moves downwards, as shown in Fig. 8~9, supports the second support ring 12 in ring assemblies that can also move down with platen 5 at this time,
But the first support ring 11 is then blocked and cannot be moved down due to the retention bead 14 on limiter 13, at this time 11 He of the first support ring
It can only be by relatively rotating the distance changed between the two, to meet shape between platen 5 and diaphragm spring 7 between second support ring 12
At new spacing height, guarantee the interaction relation between platen 5 and diaphragm spring 7.
