A Rapid Cooling and Even Temperature Brake Disc Suitable for Sports Cars

Abstract

The invention discloses a fast-cooling uniform-temperature brake disc suitable for a sports car. The fast-cooling uniform-temperature brake disc comprises a heat pipe cavity and an air duct cavity, and the heat pipe cavity is formed by two disc bodies symmetrically and fixedly connected together and inner and outer side walls in a sealed mode. When the car brakes to decelerate, heat generated after the brake disc and a brake pad are closely engaged can be transmitted from an outer ring section to an inner ring section in an internal working medium phase change mode, meanwhile, a working mediumliquefied at the inner ring section is quickly conveyed back to the outer ring section through centrifugal force generated during rotation of wheels to be subjected to heat-absorbing evaporation again, and thus self-circulating constant temperature cooling of the brake disc is achieved. The fast-cooling uniform-temperature brake disc has the beneficial effects that the heat pipe cavity of the brake disc dissipates heat and is combined with the air duct cavity in the outer side, the heat generated instantly by braking is quickly released into the environment, excessive thermal stress caused bysudden rise of the temperature of the brake disc is avoided, and thus the service life and maintenance cycle of the brake disc can be greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a fast-cooling and uniform-temperature brake disc suitable for sports cars. Background technique [0002] The brake system is an important part of the car as a whole, responsible for ensuring the safety of the car. To a certain extent, the speed of the car depends on the quality of the brakes. At present, mainstream braking systems are generally divided into disc brakes and drum brakes, and the braking components in disc brakes are composed of brake discs, brake pads, calipers and pistons. When the car brakes, the brake pads inside the calipers will rub against the brake disc violently, thereby generating braking force. However, due to severe friction, a large amount of heat will be generated and accumulated on the brake disc in a short period of time, causing the temperature of the brake disc to rise sharply, which in turn will cause the accumulation of brake heat, posing a...
