Problems solved by technology

In the impact test, if the impact force of the pump body is too large, the shock absorber cannot effectively buffer the impact force of the pump body, and the fixing bracket of the vacuum pump will break
If the bracket breaks, it will affect the function of the vacuum pump, further affect the braking performance of the car, and bring hidden dangers to driving safety
At the same time, if the bracket breaks, additional vibration and noise will be generated, which will bring about the NVH problem of the whole vehicle

Abstract

The invention provides a vibration reduction block for a vacuum pump and a vacuum pump assembly. The vacuum pump comprises a mounting lug, the mounting lug comprises a mounting lug body and a mounting lug end part, the vibration reduction block comprises a vibration reduction block body, a mounting hole corresponding to the mounting lug body is formed in the vibration reduction block body, the mounting lug body is mounted in the mounting hole, and an extension part is arranged on the vibration reduction block body. The extension part is formed by extending in the radial direction from the end, away from the vacuum pump, of the vibration reduction block body. By optimizing the structure of the vibration reduction block, the vacuum pump body is in full contact with the vibration reduction block, the buffering stroke is increased, the impact force of the pump body on a fixing support is reduced, and the vacuum pump and the fixing support are fully protected. Meanwhile, the vacuum pump assembly using the vibration reduction block has excellent anti-vibration performance, the normal function of a brake module can be ensured in the running process of the vehicle, and the noise of the vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to a vibration damping block for a vacuum pump and a vacuum pump assembly. Background technique [0002] The vacuum pump is an important part of the auxiliary braking system of the car. In the prior art, a vacuum pump consists of a vacuum pump body, a shock absorber and a vacuum pump fixing bracket. In the impact test, if the impact force of the pump body is too large, the shock absorber cannot effectively buffer the impact force of the pump body, which will cause the fixing bracket of the vacuum pump to break. If the bracket breaks, it will affect the function of the vacuum pump, further affect the braking performance of the car, and bring hidden dangers to driving safety. At the same time, if the bracket breaks, additional vibration and noise will be generated, which will cause the NVH problem of the whole vehicle. Contents of the invention [0003] To solve the above pr...
