Brake disc assembly based on air cooling system

Abstract

The invention discloses a brake disc assembly based on an air cooling system, and relates to the technical field of brake discs. The brake disc assembly comprises a boss, two disc bodies are fixedly connected to the circumferential side face of the boss, a circular ring is rotationally connected to the circumferential side face of the boss through a bearing, a plug pin penetrates through the innerwall of an annular cavity, a limiting disc is fixedly connected to the end, located in the annular cavity, of the plug pin, a limiting spring and an expansion air bag are fixedly connected to one side face of the limiting disc, one side face of the expansion air bag is fixedly connected with the inner wall of the annular cavity, and arc-shaped clamping grooves are formed in the two side faces ofthe circular ring. Through the design of the circular ring, the plug pin, the expansion air bag, the arc-shaped clamping grooves, an annular gear and fan blades, the disc bodies and the circular ringrotate differentially, automatic air cooling can be achieved, the heat dissipation effect is good, and the problems that an existing brake disc is poor in heat dissipation effect, the performance of the brake disc can be affected after long-time braking, safety is poor, brake failure is likely to happen, and traffic accidents are caused are solved.

Description

Technical field [0001] The invention belongs to the technical field of brake discs, and in particular relates to a brake disc assembly based on an air cooling system. Background technique [0002] With the progress of the times, cars are gradually becoming popular in people’s lives, bringing great convenience to people’s lives and travel, but driving also has certain safety hazards, brake failure will cause great harm, which requires The car needs to be equipped with a good brake disc. The brake systems on vehicles generally use disc and drum brake systems, among which disc brake systems are more widely used. The brake disc is an important part of the car during braking, and the performance of the car's braking directly affects the driving safety of the car. Especially for large-scale heavy-duty vehicles, due to their own inertia when braking, the brakes will have friction on the brake discs, and the temperature of the brake discs will rise rapidly. When the temperature of the...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a brake disc assembly based on an air-cooled system, through the design of rings, pins, expansion air bags, arc-shaped slots, ring gears and fan blades, the poor heat dissipation effect of existing brake discs is solved. Braking for a long time will affect the performance of the brake disc, the safety is poor, and it is easy to cause brake failure and cause car accidents
