An electronic vacuum pump mounting bracket

Abstract

An electronic vacuum pump installation bracket, which has a flat plate-shaped connection portion, and the connection portion is provided with bolt installation holes for connecting and fixing the bracket with a car body or a transmission case. There is a mounting ear on the front side of the left and right ends of the flat-shaped connecting part, and a U-shaped opening is formed between the two mounting ears and the flat-shaped connecting part to accommodate the pump body of the electronic vacuum pump. There are bolt mounting holes on the two mounting ears , for installing a fixed electronic vacuum pump. The flat-shaped connecting portion and the mounting ear are not on the same plane, they are connected through a slope surface, and the plane where the mounting ear is located is lower than the plane where the flat-shaped connecting portion is located. A line card and a wire harness bracket are arranged on the flat-shaped connecting portion. The bolt mounting hole is provided with a vibration damping washer, and the vibration damping washer is located between the flat connecting portion and the vehicle body or the transmission case, the fitting surface of the mounting ear and the electronic vacuum pump. The invention has the advantages of attenuating vibration and noise and integrating wiring harness arrangement functions, and has simple structure and small space occupation.

Description

technical field [0001] The invention belongs to the field of parts design of automobile braking safety system, and in particular relates to the structural design of an electronic vacuum pump mounting bracket. Background technique [0002] In order to ensure the stability of the vacuum degree of the vacuum booster, effectively and smoothly play the role of boosting, relieve driving fatigue, and improve the stability of the brake pedal force, the application of electronic vacuum pumps in automobiles is becoming more and more common. The electronic vacuum pump is usually arranged in the engine compartment near the vacuum booster, and is installed on the vehicle body through a mounting bracket. Limited by the size of the engine compartment and the installation space, the layout and installation of the electronic vacuum pump must meet the requirements of compact structure, effective use of space and easy installation. This requires the design structure of the electronic vacuum pu...

AI Technical Summary

Problems solved by technology

[0003] The defects of existing electronic vacuum pump mounting brackets are: a type of bracket with simple structure, which is directly connected with the pump body and the vehicle body, cannot achieve vibration and noise reduction, thereby affecting comfort; a type of bracket with vibration and noise reduction, usually The structure is relatively complicated. In addition, there are usually two more installation points with the pump body and the body, which cannot achieve the first-level assembly, and need to be sub-assembled under the final assembly line.
