Description

Mounting bracket for vacuum booster pump Technical Field The utility model relates to the technical field of mounting brackets, in particular to a mounting bracket for a vacuum booster pump. Background The vacuum booster pump is commonly called a brake booster pump, and is used for controlling vacuum entering the booster pump in the braking process, so that the diaphragm moves, and the push rod on the diaphragm is used for assisting manpower to step on and push the brake pedal through the intermodal device, so that the effect of amplifying the pedal stepping force of a driver is achieved, and the vacuum booster pump is required to be fixed by means of the mounting bracket when being mounted on the frame. In the chinese patent with publication number CN202481068U, an electric vehicle vacuum booster pump fixing mount is disclosed, which can stably fix the electric vehicle vacuum booster pump, and can effectively reduce the negative effect caused by the working vibration of the electric vehicle vacuum booster pump, so that the energy consumption is reduced, the service life is prolonged, and the braking performance of the electric vehicle is stable, thereby improving the safety performance of the electric vehicle. The vibration of vacuum booster pump is accomplished with the help of the cylindricality buffer cover in above-mentioned scheme, but because the buffer cover adopts elastic material to cushion, this leads to the vehicle vacuum booster pump to produce certain rocking when vibrating the road surface, and the vacuum booster pump needs to be connected with braking structure, this structural stability that can influence vacuum booster pump and braking structure to different braking structures need the flexible end of vacuum booster pump to be in different positions, only be difficult to play fine installation effect through the buffer cover. Therefore, we provide a mounting bracket for a vacuum booster pump to solve the above problems. Disclosure of utility model First) solving the technical problems The utility model aims to make up the defects of the prior art and provides a mounting bracket for a vacuum booster pump. Two) technical scheme In order to achieve the above purpose, the utility model provides a mounting bracket for a vacuum booster pump, comprising the following technical scheme: A booster pump body.
