Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] A clutch face sheet, the automobile clutch face sheet is made of non-asbestos composite yarn and non-asbestos cord fabric as raw materials, rosin styrene-butadiene rubber and phenolic resin are used as adhesives, and after the raw material is impregnated with resin, the raw material is impregnated with resin and dried The finished product is obtained after impregnating rubber material, winding the blank, hot pressing, heat treatment, grinding, inspection and packaging.

[0021] Specifically, the resin material in the raw material impregnation resin is prepared by mixing and stirring phenolic resin, barium sulfat...

Abstract

The invention discloses a heat treatment method for clutch facings. The heat treatment method comprises the following steps of S1, loading of the clutch facings; S2, starting of a drying over; S3, heat treatment, heating and heat preservation of the facings; and S4, material taking for detection. According to the heat treatment method for the clutch facings, by conducting heat treatment on the facings which do not reach the completely solidified and vulcanize states after being subjected to hot pressing, the facings are solidified thoroughly, and the property of a product is further improved.Compared with a traditional facing heat treatment process, the heat treatment method is simple in step and better in treatment effect.

Description

technical field [0001] The invention belongs to the field of face heat treatment, and more specifically relates to a clutch face. At the same time, the invention also relates to a heat treatment method for the clutch face. Background technique [0002] The friction part is the main component of the friction clutch, and the physical and mechanical properties of the working surface material directly affect the working performance of the clutch. The main requirements for the material are: the friction coefficient is large and stable, and the dynamic friction coefficient should be as close as possible to the static friction coefficient; the strength is high, it can withstand impact, and it is not easy to break and peel off at high speed; The deformation is small; it should not stick when left standing for a long time. In addition, long service life, easy processing and low price are also required. [0003] During the production and processing of the existing automobile clutch...
