Problems solved by technology
[0003] The technical problem to be solved by the present invention is to provide an automobile brake drum with heat-resistant and anti-wear performance in view of the above-mentioned technical deficiencies. The brake pad at the left end moves to the right, so that multiple brake pads and brake pads are pressed together, and the brake is braked under the friction between the brake pads and the brake pads. The gap between each brake pad and the brake pad Friction can be used as braking resistance, large braking area and good braking effect, which solves the problem of the outer surface of the brake shoe and the inner surface of the brake drum in traditional drum brakes. The braking area is small and the braking effect is not ideal problem; when the hydraulic cylinder retracts, the brake pads and brake pads are separated under the action of the return tension spring, and the braking state is released. The brake pads and brake pads are isolated from multiple sides to dissipate heat, and the heat dissipation area is large and the heat dissipation effect is good, which solves the problem of heat dissipation of traditional brake drums. The problem of small area and poor heat dissipation; brake heat and brake wear are concentrated on the brake pads and brake pads, and there will be no wear and tear of the brake drum

The invention relates to the technical field of brake drums, in particular to an automobile brake drum with heat resistance and wear resistance. The automobile brake drum comprises an axial multi-distance-piece brake device. In the braking process, a hydraulic cylinder pushes a brake pad at the left end to move towards the right side, therefore, multiple brake pads and arresters are pressed together, braking is achieved under the mutual friction effect of the brake pads and the arresters, friction force between each brake pad and the corresponding arrester can be used as brake resistance, thebrake area is large, the brake effect is good, and the problems that acting brake of the outer surface of a brake shoe and the inner surface of a brake drum of a traditional drum brake is small in brake area and not ideal in brake effect are solved. When the hydraulic cylinder is retracted, the brake pads and the arresters are separated under the effect of a reset tension spring, the brake state is removed, multi-face isolation heat dissipation is achieved by the brake pads and the arresters, the heat dissipation area is large, the heat dissipation effect is good, the problems that a traditional brake drum is small in heat dissipation area and poor in heat dissipation effect are solved, brake heat and brake wear are concentrated on the brake pads and the arresters, and the wear and cracking phenomena of the brake drum are avoided.
Description
technical field [0001] The invention relates to the technical field of brake drums, in particular to an automobile brake drum with heat-resistant and anti-wear properties. Background technique [0002] Due to the better braking performance of drum brakes, drum brakes are generally used for heavy-duty trucks; the working principle is to achieve braking by hydraulically pushing the brake shoe and the friction of the brake drum, and the heat generated during braking is concentrated On the outer wall of the brake drum, the heat dissipation area is small and the heat dissipation effect is poor. If the temperature of the brake drum is too high, it will often be deformed. The outer surface of the brake shoe and the inner surface of the brake drum act to brake, the braking area is small, and the braking effect is not ideal. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automobile brake drum with heat-resistant and ...
