Problems solved by technology

In many traffic accidents, the reason for the accidents of large loading vehicles, especially mining vehicles, is that the brakes failed, which caused the driver to be injured or even killed. Some accidents also caused the mining vehicle to hit other vehicles, pedestrians or buildings. Accidents caused by objects, thereby expanding the number of injured people in the accident
Most of the reasons for the failure of drum brakes are due to the overheating of the brakes. Because the traditional drum brakes are airtight, they cannot discharge the heat generated after braking well, and the braking effect of the drum brakes will be due to The braking effect is severely degraded. The diameter of the drum of the traditional drum brake will increase after being heated, which will increase the stroke of the brake pedal and cause the brake response to be less than expected.

Abstract

The invention discloses a mine car brake which comprises brake shoes, friction plates and a brake drum. The friction plates are arranged on the brake shoes. The friction plates and the brake shoes are arranged outside the brake drum. The mine car brake is characterized in that the brake shoes, the friction plates and the brake drum are arranged in a cooling shell; a cooling shell body is provided with an air inlet pipe and an air outlet pipe; the cooling shell is internally provided with a temperature sensor which transmits a temperature signal to an ECU; and the ECU can automatically control in-out of low temperature gas to cool the brake. The defects of mine car brakes are overcome through the mine car brake which is provided with the cooling shell and a ventilation cooling system, and the brake shoes of the mine car brake are arranged outside the brake drum; and the mine car brake has the functions that a good braking effect is still achieved after long-time and long-distance braking, and heat after braking is rapidly discharged.

Description

technical field [0001] The invention relates to the field of mine car brakes, in particular to a mine car brake. Background technique [0002] Brakes are used in various vehicles. Brakes have the functions of decelerating, stopping or keeping the vehicle (or moving machinery) in a stopped state. The reliability of the brake is crucial to the safety of driving, including the reliability of the brake, the braking response of the brake Factors such as time and braking distance of the brake are the key performance parameters of the brake. [0003] Vehicle brakes are usually divided into drum brakes and disc brakes. In the field of mining vehicles, drum brakes are usually used for brakes. Drum brakes have the advantages of low cost, small space, excellent braking performance, and simple maintenance. . Mining carts usually run on roads with poor road conditions, curved roads, long slopes, and steep slopes. Brakes are often used during driving, and the weight of the mining cart i...
