Abstract

The utility model discloses a vacuum pump pipeline connection structure, including the pipe clamp, set up the cushion between the pipeline outer pipe wall of vacuum pump and the pipe clamp. The elastic pad can absorb the vibration generated by the pipeline, so that the vibration is prevented from being directly transmitted into the cab through the pipe clamp, and the silence in the automobile is improved.

Description

Vacuum pump pipeline connecting structure

Technical Field

The utility model relates to an automobile assembling field, concretely relates to connection structure of vacuum pump pipeline.

Background

The vacuum pump used on the automobile is also called as a vacuum booster pump, and mainly has the main function of providing vacuum for a vacuum booster device of an automobile braking system so as to reduce the fatigue strength of the operation of the driver braking system and ensure that the automobile braking system can provide enough braking force. The vacuum pump divide into mechanical vacuum pump and electron vacuum pump, and the electron vacuum pump is the one set of operating system who provides the vacuum source outside being independent of the engine, and electron vacuum pump during operation can produce working noise, and electron vacuum pump's connecting line passes through pipe clamp and ribbon rigid connection with the automobile body, causes the mounting that vibration noise passes through connecting line and automobile body to spread into the driver's cabin, influences the silence in the car.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an improve vacuum pump pipeline connection structure of silence nature in the car.

In order to realize the purpose, the technical scheme is as follows: the utility model provides a vacuum pump pipeline connection structure which characterized in that: the vacuum pump comprises a pipe clamp, wherein an elastic pad is arranged between the outer pipe wall of a pipeline of the vacuum pump and the pipe clamp;

the elastic pad is in a ring sleeve shape and is sleeved on the outer peripheral wall of the pipeline, and the pipe clamp is clamped on the periphery of the elastic pad and fixed on the vehicle body;

the outer wall of the elastic pad is provided with an annular groove which is arranged along the circumferential direction, an annular clamping piece of the pipe clamp is arranged in the annular groove, and the axial width of the annular clamping piece is consistent with the distance between two groove walls of the annular groove.

Compared with the prior art, the utility model discloses a technological effect does: the elastic pad can absorb the vibration generated by the pipeline, so that the vibration is prevented from being directly transmitted into the cab through the pipe clamp, and the silence in the automobile is improved.

Detailed Description

The present invention will be described in further detail with reference to fig. 1 to 4.

A vacuum pump pipeline connecting structure comprises a pipe clamp 30, and an elastic pad 20 is arranged between the outer wall of a pipeline 11 of a vacuum pump 10 and the pipe clamp 30.

The elastic pad 20 can absorb the vibration generated by the pipeline 11, so that the vibration is prevented from being directly transmitted into the cab through the pipe clamp 30, and the silence in the vehicle is improved.

As a specific arrangement manner of the elastic pad 20, the elastic pad 20 is in a ring shape and is sleeved on the outer peripheral wall of the pipeline 11, and the pipe clamp 30 is clamped on the outer periphery of the elastic pad 20 and is fixed on the vehicle body 1.

The outer wall of the elastic pad 20 is provided with an annular groove 21 which is opened along the circumferential direction, an annular clamping piece 31 of the pipe clamp 30 is arranged in the annular groove 21, and the axial width of the annular clamping piece 31 is consistent with the distance between the two groove walls of the annular groove 21. The fixed elastic cushion 20 is prevented from moving along the axial direction, and the elastic cushion 20 is ensured to be fixed reliably.

The section of the elastic pad 20 perpendicular to the axial direction thereof is C-shaped. The elastic pad 20 is clamped to the pipeline 11 from the C-shaped opening, and the installation of the elastic pad 20 is greatly facilitated.

The elastic pad 20 is made of rubber.
