Description
Technical field
The utility model relates to automobile industry Clutch Technology field, especially a kind of cover & plate assy..
Background technique
Current automobile cover & plate assy. is primarily of platen, and diaphragm spring and clutch cover composition, clutch cover and diaphragm spring adopt 3-6 rivet to be equipped with upper and lower support ring assembly connection more in the prior art.
Conventional clutch platen assembly in use, when friction disc wear, platen can move to flywheel end, the distortion of diaphragm spring in operation point will reduce, therefore the operation point of clutch moves forward, visible in the greatest wear weight range of friction, the diaphragm spring impacting force of any point is all greater than work impacting force during new friction plate.The impacting force of diaphragm spring work is determined according to vehicle load needs and engine torque size when designing clutch, if little clutch can skid, and large unfavorable to preventing power train from transshipping, so the size of diaphragm spring work impacting force is the important indicator ensureing that clutch normally works.Because the friction plate of clutch in use inevitably weares and teares, thus traditional diaphragm spring clutch in use actual impacting force becoming greatly always, thus Separating force also can increase, and the increase of Separating force will reduce the travelling comfort of manipulation.Often need to increase hydrobooster to reduce Separating force for the Medium or severe type automobile that high power engine is housed, thus make clutch configuration complicated, manufacture cost increases.
Conventional clutch lid and platen assembly after a procedure Separating force are 1.1-1.5 times increasing progressively compared with initial work location, pedaling force increases progressively, although adopt self-adjusting clutch effectively can solve wearing and tearing tailboard power increase progressively problem, need larger installing space and expensive expense.
Model utility content
In view of this, the utility model provides a kind of and is not changing clutch cover and plate assembly structure, can reduce the cover & plate assy. of cover & plate assy. Separating force after wearing and tearing under not increasing the prerequisite of outer profile size.
A kind of cover & plate assy., it comprises platen, clutch cover, rivet, diaphragm spring and butterfly spring;
Platen upper punch is shaped with boss; Clutch cover is positioned on platen; Diaphragm spring is arranged between clutch cover and platen, and diaphragm spring one end abuts against on the boss of platen, and its other end extends to away from platen direction; Rivet through clutch cover and diaphragm spring, and is fixedly linked with clutch cover and diaphragm spring, has gap between rivet rivet and platen;
Butterfly spring comprises sticking part, lug boss and nip portion; Sticking part is arranged between clutch cover and diaphragm spring, and is fixedly connected with clutch cover by rivet; Lug boss one end is fixedly connected with sticking part, and its other end is fixedly connected with nip portion; Nip portion and diaphragm spring are near the end face pressing of clutch cover.
Compared with prior art, its advantage is the cover & plate assy. that the utility model provides:
The utility model device by increasing belleville spring on conventional clutch lid and platen assembly, according to belleville spring incremental force properties counteract or the reduction clutch abrasion state Separating force of belleville spring, can clutch cover and plate assembly structure do not changed, under not increasing the prerequisite of outer profile size, reduce the rear cover & plate assy. Separating force of wearing and tearing.

Embodiment
As shown in Figure 1, 2, at a kind of cover & plate assy. of the utility model embodiment, it comprises platen 1, clutch cover 2, diaphragm spring 3, rivet 4, butterfly spring 5, locating piece 6.
Platen 1 upper punch is shaped with boss 11; Clutch cover 2 is positioned on platen 1; Diaphragm spring 3 is arranged between clutch cover 2 and platen 1, and diaphragm spring 3 one end abuts against on the boss 11 of diaphragm spring 3, and its other end extends to away from platen 1 direction; Rivet 4 through clutch cover 2 and diaphragm spring 3, and is fixedly linked with clutch cover 2 and diaphragm spring 3, has gap between rivet 4 and platen 1.
Butterfly spring 5 comprises sticking part 51, lug boss 52 and nip portion 53; Sticking part 51 is arranged between clutch cover 2 and diaphragm spring 3, and is fixedly connected with clutch cover 2 by rivet 4; Lug boss 52 one end is fixedly connected with sticking part 51, and its other end is fixedly connected with nip portion 53; Nip portion 53 and the end face pressing of diaphragm spring 3 near clutch cover 2.Electedly, lug boss 52, in arch, makes butterfly spring 5 meet the spring force characteristics of butterfly spring 5 as shown in Figure 3.
Locating piece 6 is fixed between platen 1 and diaphragm spring 3 by rivet 4; Locating piece 6 one end and rivet 4 are fixed, and its other end supports the end face of diaphragm spring 3 near platen 1.
Preferably, locating piece 6 with support diaphragm support a little compared to the pressing point of nip portion 53 and diaphragm spring 3 near rivet 4.Alternatively, locating piece 6 is two annular rings, and the form of certain locating piece 6 is not limited only to this.
Principle of the present utility model is as follows:
As shown in Figure 3, Fig. 3 is the spring force characteristics figure of butterfly spring 5, the shape of butterfly spring 5 meets following requirement: calculate (A-L method) according to the load-deflection of belleville spring, be designed to a kind of incremental force characteristic curve, therefore the utility model can utilize belleville spring incremental force properties counteract or reduce clutch abrasion state Separating force.
