Abstract

The invention discloses a safe low-temperature brake which comprises a brake hub, brake pieces and a brake foot, wherein the brake hub is connected with a hub; the brake foot is connected with a shaft head; through pivot holes are formed in the brake hub wall and the brake pieces respectively; the brake pieces are fixedly connected with the inner wall of the brake hub through hollow pivots. The brake pieces of the safe low-temperature brake are fixedly connected with the inner wall of the brake hub through the hollow pivots, so that air inside and outside the brake hub can be circulated, heat dissipation is facilitated, the air can be 'thrown' out under the centrifugal force when the brake hub is rotated in an automobile running process, the air inside the brake hub can be continuously replaced, and the temperature of a brake assembly can be rapidly and effectively reduced, so as to effectively prevent the situation that the brake hub is too hot or fire is caused to a tire; the air can be replaced, at the same time particles caused by friction can be discharged out in time, the smoothness of a friction surface can be improved, the brake effect can be ensured, and furthermore the service lives of the brake pieces and the brake foot can be prolonged.

Description

technical field [0001] The invention relates to the field of automobile brakes, in particular to a safe low-temperature brake. Background technique [0002] Automobile brakes are divided into two categories: hub type and disc type, both of which are friction type, that is, to brake the moving vehicle through friction. The current hub type brakes are all closed structures, and the heat generated during the friction process is easy to accumulate. Continuous braking of the vehicle, especially when the heavy-duty vehicle is continuously braking on a long slope, the temperature of the brake hub will gradually rise to hundreds of degrees Celsius, which will cause the brake hub to overheat and crack and cause the brake to fail, which will easily cause road safety accidents. When the brake hub When the temperature exceeds the vulcanization temperature of the tire rubber, the tire is easy to catch fire and cause a fire accident. Contents of the invention [0003] The technical pro...
