Abstract

The invention discloses a spring rivet for a driving disc of an automotive air conditioning clutch. The spring rivet comprises a rivet body and a rubber part, and one end of the rivet body is embedded in the rubber body. The rubber body is made from, by weight, 95-105 parts of butadiene-acrylonitrile rubber, 42-48 parts of fast extruded carbon black, 1-2 parts of plasticizers, 0.8-1.2 parts of stearic acid, 1.8-2.2 parts of BLE 1.8-2.2 parts, 4.7-5.2 parts of zinc oxide, 0.4-0.6 part of S-80 and 0.8-1.2 parts of DPTT. By taking advantage of rubber resilience, return of a magnet can be guaranteed timely and accurately by the spring rivet when a coil is powered off, and accordingly separation of fitting faces is guaranteed; the spring rivet made of rubber is lightened in weight to some extent, and the magnet and a belt pulley can be combined easily under the action of attraction force generated by the electrified electromagnetic coil; during attraction, the spring rivet is low in noise and stable in operation and enables passengers to feel comfortable.

Description

technical field [0001] The invention relates to an automobile air-conditioning clutch, in particular to a spring rivet for a driving disc of an automobile air-conditioning clutch. Background technique [0002] The automobile air conditioner electromagnetic clutch is a power transmission device between the automobile engine and the automobile air conditioner compressor. The automobile air conditioner compressor is driven by the automobile engine through the electromagnetic clutch. The electromagnetic clutch is a device used to disconnect or connect the power of the air conditioner compressor. The stop and start of the compressor are determined by the release and pull-in of the electromagnetic clutch. The driving disc is composed of iron suction, return elastic body, shaft sleeve, balance plate and other components. In the prior art, the return spring is generally a spring steel sheet, but the spring steel sheet returns slowly due to poor elasticity, causing the clutch to of...
