Abstract

The invention relates to an automobile clutch pipe with high temperature resisting, brake oil resisting, temperature change resisting, varying load pulse resisting performances and the like. A hydraulic-controlled clutch pipe comprises an inner rubber layer, a braiding layer and an outer rubber layer from inside to outside, the inner rubber layer uses ethylene propylene diene monomer as a main body material, the outer rubber layer uses chloroprene rubber as the main body material, and the braiding layer is made of a vinylon fiber material. The hydraulic-controlled clutch pipe and a production process thereof have the advantages that the design is optimized according to the formula, the ethylene propylene diene monomer and the chloroprene rubber respectively serve as the inner rubber layer and the outer rubber layer of the clutch pipe, the inner rubber layer has good brake oil resisting performance and high temperature thermal ageing resisting performance, the outer rubber layer has good machine oil resisting performance and high temperature thermal ageing resisting performance, and the rubber material has excellent physical and mechanical properties and good processing performance. The tensile strength and the hardness retention rate of the hose subjected to thermal ageing are high, no extraction is produced after the hose is soaked in DOT4 synthetic brake fluid, the standard requirements are met completely, and safety of a whole automobile is guaranteed.

Description

technical field [0001] The invention relates to an automobile clutch hose with properties such as high temperature resistance, brake oil resistance, and variable temperature and load pulse resistance. Specifically, ethylene-propylene rubber and neoprene rubber are used as the inner and outer rubber layers through reasonable rubber formula design. A process and method for making a hydraulically operated clutch tube. Background technique [0002] The clutch hose is a very important safety component in the automobile brake system, which plays the role of transmitting the brake working pressure, and it has practical significance to improve the reliability and service life of the clutch hose. Clutch tubes are required to have excellent properties such as high temperature resistance, brake oil resistance, variable temperature resistance, and variable load pulse performance. At present, the inner rubber layer of this kind of hose produced in China usually adopts ordinary sulfur vu...
