Abstract

An electric brush for ABS (Anti-skid Brake System) comprises a brush body and a lead-out wire, wherein the brush body comprises 46 to 52 parts by weight of superfine electrolytic copper powder, 52 to 46 parts by weight of cementing powder and 2 parts by weight of modifier at; the cementing powder comprises 1.0 to 3.0 parts of high-purity carbon fiber powder, 23 to 27 parts of artificial graphite powder, 25 to 35 parts of high-purity sub-nanometer graphite powder, 18 to 22 parts of crystal graphite powder, 3 to 8 parts of graphitized carbon black powder, 2.5 to 4.5 parts of rare-earth tungsten disulfide composites and 5 to 15 parts of high-temperature resistant phenolic resin; and the modifier comprises 0.20 to 1.30 parts of vulcanization silver powder, 0.20 to 1.5 parts of stibonium powder and 0.5 to 1.5 parts of zinc powder. The chemical stability, the lubricating property, the electrical conductivity, the high-temperature resistance and the abrasion resistance of the electric brush provided by the invention are much better than that of the existing products.

Description

technical field [0001] The invention relates to an electric brush, in particular to an electric brush with super long service life, especially stable and reliable output power, which is suitable for electric energy transmission of motors in ABS brake anti-lock braking systems of automobiles and a preparation method thereof. Background technique [0002] Automobile braking system is closely related to the safe driving of automobiles. In case of an emergency, a vehicle that is not equipped with an ABS system has no time to brake slowly in stages and can only be trampled to death immediately. Due to the sprinting inertia of the vehicle, dangerous situations such as sideslip, deviation of the driving track, and uncontrolled direction of the vehicle body may occur in an instant. The invention of the ABS automobile anti-lock braking system has greatly improved the safety of the automobile in emergency situations. It is a safety device that can effectively prevent the wheel from ...
