Abstract
The utility model relates to an anti-deformation device for driving pieces of clutches, which belongs to the technical field of automobiles. The utility model is composed of a pressure plate ear widened on a pressure plate and an anti-deformation rivet. The utility model is characterized in that the width of a gap between the pressure plate ear widened on the pressure plate and the anti-deformation rivet is alpha, and the alpha ranges from 3mm to 4mm; the small end of the anti-deformation rivet and the riveting point of a transmission sheet are provided with an anti-rotation non-circular cross section; the other end of the anti-deformation rivet is provided with the big end which can prevent the pressing plate from ejecting, and the width of a protruding edge of the big end is larger than the alpha. The utility model has the advantages that the pressure plate can not be dropped and suspended after being limited by the anti-deformation rivet in the process of transportation, and the function of preventing the plastic deformation of the transmission sheet can be obtained.
Description
(1) technical field: the utility model relates to automobile technical field, is the driver blade anti-deformation device of automobile component power-transfer clutch.
(2) background technology: all adopt diaphragm-spring clutch on the present all kinds of automobiles, connect and support by four driver blades between the clutch cover back plate of this power-transfer clutch and the platen, when power-transfer clutch as parts in handling process, because platen is subjected to driver blade to be supported on the state of suspending, driver blade plastic deformation usually appears, driver blade was lost efficacy, cause occurring power-transfer clutch work mal.
(3) summary of the invention: the purpose of this utility model is at above-mentioned existing problems, provides a kind of and prevents in carrying, the anti-deformation device of driver blade.
The technical solution of the utility model is: the clutch driving strap anti-deformation device is made up of platen ear of widening on the platen and anti-deformation rivet, it is characterized in that: the platen ear of widening on the platen is wide to be α to the gap with the anti-deformation rivet, and α gets 3-4mm; The riveted place of the microcephaly of anti-deformation rivet and driver blade all has the non-circular cross-section of rotation-prevention, and the other end of anti-deformation rivet has the major part that anti-platen is deviate from, and the hem width that major part is given prominence to is greater than α.
The beneficial effects of the utility model are: in carrying way, platen is subjected to that the restriction of anti-deformation rivet is unlikely deviates to suspend, and plays a part to protect driver blade not produce plastic deformation.
(4) description of drawings:
Fig. 1 is that the position of driver blade concerns scheme drawing;
Fig. 2 is an anti-deformation rivet shape scheme drawing;
Fig. 3 is a driver blade plan view shape scheme drawing;
Fig. 4 is the platen birds-eye view.
Among the figure: 1-clutch cover back plate, 2-platen, 3-driver blade, 4-anti-deformation rivet.
(5) specific embodiment:
Referring to Fig. 1,2,3,4; the utility model is a kind of improvement invention; in producing enforcement; must not increase part and processing technology; after only platen [2], driver blade [3] and anti-deformation rivet [4] need being improved mould by requirement of the present utility model, assembly just can realize that the protection driver blade does not produce the purpose of plastic deformation in power-transfer clutch carrying on the way.Fig. 3 has shown that non-circular rotation-prevention rivet hole is the non-circular hole with two string limits, and Fig. 4 has shown the shape that the platen ear is widened.
Claims (1)
1. the clutch driving strap anti-deformation device is made up of platen ear of widening on the platen [2] and anti-deformation rivet [4], it is characterized in that: the platen ear of widening on the platen [2] is wide to be α to the gap with anti-deformation rivet [4], and α gets 3-4mm; The riveted place of the microcephaly of anti-deformation rivet and driver blade [3] all has the non-circular cross-section of rotation-prevention, and the other end of anti-deformation rivet has the major part that anti-platen [2] is deviate from, and the hem width that major part is given prominence to is greater than α.
