High-heat-dispersion carbon brake disc for car and manufacturing method thereof

Abstract

The invention discloses a high-heat-dispersion carbon brake disc for a car and a manufacturing method thereof and particularly relates to the technical field of brake discs. The high-heat-dispersion carbon brake disc comprises an inner brake pad. An outer brake pad is arranged on the top of the inner brake pad. The outer brake pad and a middle cylinder body of the inner brake pad are arranged in asleeved connecting manner. A heat dissipating and pressure bearing part is fixedly arranged between the inner brake pad and the outer brake pad. A brake pincer shell is arranged on the outer side ofthe inner brake pad and the outer side of the outer brake pad in a matched manner. Brake pincers are arranged in the brake pincer shell. An installing ring is arranged on an inner ring of the outer brake pad. A cooling water ring is arranged on the bottom of the installing ring. According to the brake disc, cooling water flows in the cooling water ring, heat is absorbed under cooperation with a heat exchange blade, an electromagnet is electrified to drive a water separating collar to descend, thus the water separating collar descends to the lower side of a water passing opening, the cooling water is directly conveyed to a water spraying head, the water is sprayed to the inner brake pad and the outer brake pad for heat dissipation, different requirements for heat dissipation of the brake discs can be met conveniently, and the heat dissipating effect is improved.

Description

technical field [0001] The invention relates to the technical field of brake discs, in particular to a high heat dissipation carbon brake disc for automobiles and a preparation method thereof. Background technique [0002] The brake disc is an essential part of all vehicle braking systems. It is fixed on the axle and rotates with the wheel. When braking, the brake block is pressed onto the brake disc under the push of the caliper piston. Through the brake block and the The friction between the brake discs reduces the wheel speed to achieve the purpose of vehicle deceleration and braking. With the acceleration of the vehicle, the brake disc will bear the pressure and friction of the brake block, and wear will occur in the relative movement with the brake block, especially when there are debris such as sand and gravel on the working surface, the wear will be more serious. Seriously, greatly shorten the service life of the brake disc. Therefore, the material for making the br...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following deficiencies: common brake discs are made of single materials such as malleable cast iron, gray cast iron, and nodular cast iron. The heat dissipation effect of the brake disc is not ideal, so the multi-way heat dissipation is conducive to the use of the brake disc
