Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a thermal fade resistant brake disc device. Background Art

[0002] Disc brakes, also known as disc brakes, are named after their shape. They are hydraulically controlled and their main components include the brake disc, oil pump, brake caliper, and oil pipe. The brake disc is made of alloy steel and fixed to the wheel, rotating with the wheel. The oil pump is fixed to the brake base plate and remains stationary. The two friction pads of the brake caliper are mounted on either side of the brake disc. The oil pump's piston, driven by hydraulic pressure from the oil pipe, pushes the friction pads against the brake disc, generating friction braking. This action is like clamping a rotating disc with pliers to stop it. The brake disc heats up due to friction. When heated to a certain temperature, the material loses strength, affecting braking performance and the life of the disc.

[0003] For example, Chinese patent publication (announcement) number CN216951414U discloses a semiconductor cooling vehicle brake disc device, comprising: a brake caliper mounted on the outer periphery of the brake disc, a first oil pump mounted on the caliper; a first semiconductor cooler mounted on the caliper; a second semiconductor cooler connected to the second oil pump, which is mounted on a support frame connected to the brake caliper, and the second oil pump drives the second semiconductor cooler toward or away from the brake disc. This utility model solves the problem in the prior art that high temperatures during use of automotive brake discs affect braking performance and the service life of the brake disc.
