Said limit spring is the L type, and the perpendicular end of its L type is fixed on the limiting stopper inboard, and horizontal end is fixed on the platen.

The little head end of said wedge block is processed with spring connecting hole.

Self-regulating push type clutch working principle: when the clutch drived disk assy friction plate uses the back wearing and tearing, press total platen to move down, this moment, limiting stopper will be held limit spring, and limit spring is no longer exchanged the domain has pressure.The wedge block of wedge block spring pulling is simultaneously also held limit spring.Adjustment encircles under adjustment ring spring tension, and two inclined-planes of adjustment ring just produce slide relative, to compensate the space that platen moves down.Thereby guarantee that clutch assembly is in the initialization state all the time; Make the work impacting force of clutch be in relative constant state all the time.Can guarantee like this clutch work reliability and operating device with stability.

The present invention has following characteristics:

1, working stability normal film lamella clutch in use, when from total friction disc wear to the diaphragm peak, its Separating force is bigger more than 30% than the Separating force of original state; That have even reach 50%; Separating mechanism to car load causes very big influence like this, and this problem never is well solved, and the self-regulating clutch in use; Can make the position, operation point keep constant relatively through adjustment ring and relevant regulating mechanism.Separating force changes not quite like this, and is very little to the control system influence.After having avoided clutch to use a period of time, the phenomenon that clutch pedal is sent out heavy, the clutch frequency of utilization is high on the passenger vehicle especially, just requires the stable of clutch separation characteristic, and fine this type of problem that solved of self-regulating clutch.

2, assembling is convenient because the self-regulating clutch is all adorned anti-loosening bolt in being in the initialization state position before dispatching from the factory, and assembly is very laborsaving when the entrucking construction bolt, also improves installation efficiency.It is highly specialized that part is made and assembled.But to pull down anti-loosening bolt after noting installing clutch.Not so clutch can not effectively be worked.

3, release bearing gap ordinary clutch need not be often adjusted and free pedal travel (being release bearing and the gap of separating between the finger) will be adjusted in use for some time.If the user is unfamiliar with or in time do not adjust its gap, can cause the release bearing premature failure, reach bad phenomenon such as cltuch slipping.And the jointing altitude of self-regulating clutch is constant relatively, need not ask frequent adjustment operating mechanism.It is very big convenient to bring to the user.
