Embodiment 1

[0012] Reference figure 1 , On both sides of the pressure plate pin lug body 2 of the clutch pressure plate 1 are provided with a pin lug reinforcement rib 3, the pin lug reinforcement rib 3 and the pressure plate pin lug body 2 are integrally cast, wherein the pressure plate pin lug body 2 is 22mm in length, The thickness is 20 mm, the length of the pin lug reinforcement 3 is 22 mm, the width is 11 mm, and the height is equal to the height of the pressure plate pin lug body 2. The pin lug reinforcing rib 3 not only enhances the strength of the pressure plate pin lug body 2, but also prevents the separation lever pin 5 from falling off due to the damage of the elastic retaining ring 4 during use.

Embodiment 2

[0014] The length of the lug body 2 of the pressure plate is 22mm, the thickness is 20mm, the length of the lug reinforcement 3 is 13.2mm, and the width is 4mm, and the rest is the same as in the first embodiment.

Abstract

The invention provides a method for stiffening the strength of clutch pressure plate pin, whose feature is indicated that setups a pin stop-off strip at each side of the pressure plate pin body and make integrated casting with the pin stop-off strip and the pressure plate pin. The invention has the excellent feature of stiffening the strength of pressure plate pin and prevent the desquamation of the separated pry bar pin for the attaint of the elastic collar during the use as the stop-off strip and pressure plate pin are cast integrated.

Description

Technical field [0001] The invention relates to automobile manufacturing, in particular to a method for strengthening the strength of a clutch pressure plate pin ear. Background technique [0002] At present, the clutch pressure plate of domestic automobile clutch manufacturers generally adopts a flat pin lug structure. The strength of the pressure plate pin lug of this structure is low, and the pressure plate pin lug may be broken during use, and the separation lever pin may fall off due to the damage of the elastic retaining ring. Summary of the invention [0003] The purpose of the present invention is to disclose a method for strengthening the pin lug strength of the clutch pressure plate in order to overcome the shortcomings of the prior art. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A method for strengthening the strength of the pin lug of a clutch pressure plate is based on the existing flat pin lug struc...
