Embodiment Construction
[0018] 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.
[0019] An automobile clutch friction plate, the automobile clutch friction plate is made of phenolic resin and styrene-butadiene rubber as adhesive, non-asbestos cloth is used as reinforcing material, then an appropriate friction material regulator is added, and the asbestos-free cloth is soaked in resin , impregnated with rubber, and then made after winding around the embryo, hot pressing, heat treatment, and grinding.
[0020] Specifically, the friction material is one or more of potassium feldspar, carbon black, graphite, and clay.
[0021] Specifically, the ratio between the asbestos-free cloth and the phenolic re...

The invention discloses a heat treatment method of an automobile clutch friction plate. The heat treatment method comprises the following steps that S1, raw materials are arranged; S2, normalizing treatment is carried out for the first time; S3, normalizing treatment is carried out for the second time; S4, normalizing treatment is carried out for the third time; and S5, tempering treatment is carried out. According to the heat treatment method of the automobile clutch friction plate, the heat treatment process of a conventional paper-based friction plate is simplified, and the process is shortened into three-time normalizing and one-time tempering, the middle carbide distribution of the whole workpiece is more uniform through three-time normalizing, so that the mechanical property of the workpiece can be effectively improved; and the stress in the workpiece can be removed through one-time tempering, so that the stability of the internal structure of the workpiece is improved; and compared with a traditional friction plate heat treatment process, the steps are simple, and the treatment effect is better.
Description
technical field [0001] The invention belongs to the field of friction plate heat treatment, and more specifically relates to an automobile clutch friction plate. At the same time, the invention also relates to a heat treatment method for the friction plate of the automobile clutch. 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 standing for a long time. In addition, long service life, easy processing and low price are also required. Commonly used friction s...
