Brake drum assembly structure

Abstract

The invention provides a brake drum assembly structure, comprising a brake drum, a friction plate and a brake shoe; a rotating shaft fixing block is fixedly installed on the inner side of the bottom of the brake drum; the inner side of the hydraulic cylinder is movable and symmetrically installed with two pistons; one side of the top of the two brake shoes is tangent to one side of the two pistons respectively; a friction plate is fixed and installed on the outer side of the brake shoes by rivets. The setting of the friction plate and the brake shoe is beneficial to the safety of use. When installing the friction plate of this device, firstly embed all the square protrusions on the side of the friction plate into the square groove on the side of the brake shoe. Then pass the rivet through the square protrusion on one side of the friction plate and insert it into the square groove on the side of the brake shoe, so that the friction plate can be firmly fixed, which can effectively increase the friction plate and braking effect. The lateral and longitudinal friction between the shoes can effectively prevent the friction pads from shifting during use and ensure a good braking effect.

Description

technical field [0001] The invention belongs to the technical field of automobile brake mechanisms, and in particular relates to a brake drum assembly structure. Background technique [0002] At present, with the development of automobile technology, the braking methods and effects of automobiles have also increased and strengthened. In the contemporary era where automobile performance is getting better and faster and driving speed is getting faster and faster, there are more and more traffic accidents, many of which are Many traffic accidents are caused by the poor braking effect of automobiles. Therefore, improving the braking effect of automobiles is the most important measure to reduce traffic accidents. The automobile braking system is a very complicated system. Whether the automobile braking system is effective Qualification depends on whether the car can slow down or stop according to our wishes. The braking principle of the car brake system is to convert the kinetic ...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a brake drum assembly structure to solve the problem that the friction lining inside the existing brake drum is mostly a relatively smooth arc-shaped plate structure, which is directly fixed on the brake drum by rivets during installation. One side of the shoe, but the tangential surface of the friction plate and the brake shoe is relatively smooth, which brings relatively low friction, while the side of the friction plate will contact the inner wall of the brake drum during braking, and will bring Larger friction force, the position of the friction plate may shift due to long-term use, resulting in a decrease in braking efficiency
