Description

Brake pad support structure Technical Field The utility model relates to the technical field of railway vehicle braking systems, in particular to a brake pad support structure. Background The basic braking device is an important component of a train braking system and mainly comprises a clamp unit, brake pads and a brake disc, and the working principle of the basic braking device is as follows: when the train brakes, the clamp unit is used as a force application component to apply normal force to the brake pad, so that the brake pad and the brake disc are contacted with each other to generate braking moment, and the effect of train deceleration braking is achieved. The brake pad support is a part connected and installed on the clamp unit, and the brake pad is installed on the brake pad support and is contacted with the brake disc to play a role of friction braking. The existing brake pad support is mainly used for installing the brake pad in a mode that the dovetail groove is formed in the bottom, but obviously cannot be used for installing the brake pad of a non-dovetail structure type, different brake pad supports are usually required to be designed, and therefore the existing brake pad support and the brake pad can only be installed in a single matching mode, the installation universality of the existing brake pad support is poor, and development and maintenance cost can be increased. Disclosure of utility model Therefore, the technical problem to be solved by the utility model is to overcome the problems that the prior art has poor installation universality and can increase development and maintenance cost because only single matching installation is usually carried out between the brake pad support and the brake pad, so that the brake pad support structure with simple installation structure, good installation universality and cost reduction is provided.
