Abstract

The invention discloses an automotive cable of an anti-locked braking system and a manufacturing method thereof. The manufacturing method comprises the following steps: (1) preheating a stranded conductor; extruding a TPE (thermoplastic polyurethane elastomer) on the stranded conductor at the temperature of 160-220 DEG C to form an insulating layer; and directly water cooling to obtain an insulating wire core, wherein the diameter of the stranded conductor is below 0.10mm, and the section surface is 0.5-1.0mm<2>; (2) stranding two to seven insulating wire cores to obtain the stranded insulating wire core; extruding polyether-type TPU (thermoplastic polyurethanes) in double layers on the stranded insulating wire core by a semi-extruded die; forming an inner layer sheath between a die core and the insulating wire core by the polyether-type TPU; and forming an outer layer sheath between the die core and a die sleeve by the polyether-type TPU, wherein the die core angle is 25-35 degrees, the die sleeve angle is 30-40 degrees, and the double-layer extruding temperature is 160-220 DEG C. The automotive cable of the anti-locked braking system is suitable for being laid in a temperature and humidity alternating environment in an automobile; the automotive cable of the anti-locked braking system is good in flexibility and high in roundness, and has oil resistance and wear resistance; and the surface of the automotive cable is in a matte state.

Description

technical field [0001] The invention relates to the field of cables, in particular to an anti-lock braking system automobile cable and a manufacturing method thereof. Background technique [0002] With the progress of society, people's living standards are gradually improving, the needs and requirements for cars are getting higher and higher, and consumers' safety awareness is getting higher and higher. Vehicle manufacturers' improvements to the anti-lock braking system (abbreviated as ABS) also tend to improve the handling and stability of the vehicle from initially only preventing the wheels from locking up during braking. In recent years, ABS has become more complex and includes not only antiskid adjustments to prevent drive wheels from being driven during acceleration, but also brake pad condition monitoring and electronic stability programs. While ABS continues to improve, it also puts forward higher requirements for the material and structure of ABS cables. [0003] ...
