Embodiment Construction

[0018] A brake pump provided by the present invention includes a pump body and a piston. The pump body is made of cast iron, and a cladding layer is provided on the inner wall of the pump body. The thickness of the cladding layer is 30-60um.

[0019] In the present invention, a cladding layer is provided on the inner wall of the pump body, and the thickness of the cladding layer is 30-60um. After chrome plating, the surface strength of the inner wall of the pump body is obviously improved, and the brake pump has higher wear resistance and corrosion resistance. , thereby improving the service life of the brake pump, improving the braking safety of the vehicle, and reducing the production cost of the brake pump.

[0020] The present invention also proposes a production method of the above-mentioned brake pump, comprising:

[0021] The pump body is made of cast iron material;

[0022] Put the pump body in an electroplating tank filled with chrome solution for chromium plating. T...

Abstract

The invention provides a brake pump and a production method thereof. The brake pump comprises a pump body and a piston, wherein the pump body is made of cast iron material, a chrome plating layer is arranged on the inner wall of the pump body, the thickness of the chrome plating layer is 30-60 um, and the surface strength of the inner wall of the chrome-plated pump body is remarkably improved. The brake pump has higher wear resistance and corrosion resistance, so that the service life of the brake pump is prolonged, the brake safety of an automobile is improved, and the production cost of the brake pump is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle brakes, in particular to a brake pump and a production method thereof. Background technique [0002] In the drum brake system of existing vehicles, the brake master cylinder and the brake sub-cylinder (collectively referred to as the brake pump) often have the phenomenon of unilateral braking and slow reset of the brake pads. The service life of the brake pump is very limited. For example, medium trucks generally have three The brake cylinder needs to be replaced once a month; in the actual working process, the single side of the brake will cause the vehicle to roll over, and the slow reset of the brake pad will cause the brake drum to heat up, which will aggravate the wear of the brake pad and shorten the life of the brake pad , The slow reset of the brake pads also causes the vehicle to drive under long-term braking conditions, and the vehicle will produce higher fuel consumption. [0003] Thro...
