Abstract
The utility model discloses a compressed clutch cover assembly with auxiliary membrane, which comprises a pressing disc, a pressing cover, a main diaphragm spring, a supporting rivet and supporting rings, wherein an annular auxiliary diaphragm spring is filled under the main diaphragm spring, the supporting rivet penetrates through the main diaphragm spring and is riveted with the auxiliary diaphragm spring and the pressing cover, and the upper end surface of the main diaphragm spring and the lower end surface of the auxiliary diaphragm spring are respectively provided with the supporting rings which are sleeved on the external side of the supporting rivet. The assembly has the advantages that the technical difficulty is reduced, the fatigue service life of the diaphragm spring is prolonged, and the torque transmission ability is improved.
Description
Technical field
The utility model relates to the improvement of auto parts and components, specifically is a kind of clutch cover and plate assembly that auxiliary diaphragm compresses that has.
Background technique
At present, the clutch major part of using in the various at home vehicles is the one chip diaphragm spring clutch.This structure clutch is owing to be subjected to the restriction in motor, gearbox space, and its clutch maximum outside diameter is restricted, and the impacting force of diaphragm spring can't break through limiting value, and torque transmission capacity is limited.In at present domestic, in the heavy-duty car generally the cltuch slipping of reaction, burn sheet, separate Accident due to qualitys such as unclear, relevant mostly therewith.In order to solve this type of problem, domestic some main engine factory have to select for use larger diameter clutch product at present, change flywheel structure, gearbox designs, and change chassis system structure causes cost to increase.Adopt the single-iris spring on the other hand, in order to reach bigger impacting force, the thickness of diaphragm spring often selects greatlyyer, diaphragm spring shaping angle is big, the consequence that causes is a diaphragm spring heat treatment process difficulty, and the diaphragm spring internal stress is bigger, is easy to generate fatigue failure.
The model utility content
The utility model provides a kind of clutch cover and plate assembly that auxiliary diaphragm compresses that has, and it has the advantage that the technology difficulty of making reduces, prolong and torque transmission capacity is improved the fatigue life of diaphragm spring.
The technical solution of the utility model is:
Have the clutch cover and plate assembly that auxiliary diaphragm compresses, include platen, gland, main film spring, supporting rivet, supporting ring, it is characterized in that: described main film spring below is lined with the auxiliary diaphragm spring of annular, described supporting rivet passes the main film spring and auxiliary diaphragm spring, gland are riveted, and main film spring upper-end surface and auxiliary diaphragm spring lower end surface are respectively equipped with supporting ring and are enclosed within the supporting rivet outside.
Describedly have a clutch cover and plate assembly that auxiliary diaphragm compresses, it is characterized in that: described auxiliary diaphragm spring is one or more pieces.
The clutch cover and plate assembly structure that has the auxiliary diaphragm spring compression of the present utility model, the thickness of diaphragm spring reduces, the shaping angle is less, diaphragm spring dish spring portion size diminishes, technology difficulty is reduced, the invalid distortion of diaphragm spring when separating reduces, and prolongs the fatigue life of diaphragm spring simultaneously.The clutch cover and plate assembly impacting force that has the auxiliary diaphragm spring compression generally is more than 1.5 times of single-iris pressing force of the spring, solved the problem of impacting force effectively, torque transmission capacity is greatly improved, and separating effect is better, can effectively guarantee the normal initial starting shift of automobile.

Fig. 1 is a structural representation of the present utility model.
Embodiment
Have the clutch cover and plate assembly that auxiliary diaphragm compresses, include platen 1, gland 2, main film spring 3, supporting rivet 4, supporting ring 5, main film spring 3 belows are lined with the auxiliary diaphragm spring 6 of annular, supporting rivet 4 passes main film spring 3 and auxiliary diaphragm spring 6, gland 2 riveted joints, main film spring 3 upper-end surfaces and auxiliary diaphragm spring 6 lower end surfaces are respectively equipped with supporting ring 5 and are enclosed within supporting rivet 4 outsides, and auxiliary diaphragm spring 6 is a slice.
Claims (2)
1, has the clutch cover and plate assembly that auxiliary diaphragm compresses, include platen, gland, main film spring, supporting rivet, supporting ring, it is characterized in that: described main film spring below is lined with the auxiliary diaphragm spring of annular, described supporting rivet passes the main film spring and auxiliary diaphragm spring, gland are riveted, and main film spring upper-end surface and auxiliary diaphragm spring lower end surface are respectively equipped with supporting ring and are enclosed within the supporting rivet outside.
2, according to claim 1ly have a clutch cover and plate assembly that auxiliary diaphragm compresses, it is characterized in that: described auxiliary diaphragm spring is one or more pieces.
