Abstract
The invention relates to a connecting device between an electric vacuum pump for an automobile and an installing support frame, in particular to an elastic shock absorbing device for connection between the electric vacuum pump and the installing support frame. The elastic shock absorbing device comprises at least one connecting screw, an elastic shock absorbing pad, an installing support frame and an electric vacuum pump body, wherein the connecting screw passes through a center hole formed in an inner round tube of the elastic shock absorbing pad and is connected with the electric vacuum pump body so that one end surface arranged on the inner round tube of the elastic shock absorbing pad is in contact with a screw arranged on the connecting screw, and the other end surface is in contact with the electric vacuum pump body, so the elastic shock absorbing pad is fixedly arranged on the electric vacuum pump body. The device provided by the invention belongs to the elastic shock absorbing device with the advantages that the structure is compact, the shock absorbing performance is good, the assembly is convenient, and the influence caused by the vibration during the vacuum pump operation on the automobile taking comfort can be effectively avoided, so the requirements provided for the taking comfort when the electric vacuum pump for the automobile is adopted as a vacuum source can be met.
Description
Technical field
The present invention relates to the connecting device between a kind of Vehicular electric vacuum pump and mounting bracket, between a kind of electric vacuum pump and mounting bracket, be connected and use elastic shock-absorbing device specifically.
Background technology
Propulsion source when automobile brake booster uses vacuum widely as its work, generally provides vacuum source by driving engine or vacuum pump (mechanical type or electrodynamic type) to it.
Electric vacuum pump can inevitably produce in the running certain vibrations and by mounting bracket, vibrations is delivered to auto body.
Electrodynamic type vacuum pump body is connected with the mounting bracket being fixed on auto body by connecting device.The vibrations that produce when electric vacuum pump running also can pass to mounting bracket by connecting device.
This vibrations will directly affect the travelling comfort of automobile.This connecting device that just need to develop advantages such as having compact conformation, damping performance is good, easy to assembly connects electric vacuum pump and mounting bracket.Like this, could reduce as far as possible electric vacuum pump running time, be delivered to the vibrations on vehicle body by mounting bracket, meet automobile to travelling comfort requirement.
Summary of the invention
The object of the invention is to provide a kind of compact conformation, damping performance good, easy to assembly, the elastic shock-absorbing device of the impact of the vibrations that can effectively improve vacuum pump when running on vehicle ride comfort, thus while meeting electric vacuum pump for automobile as vacuum source to travelling comfort requirement.
The object of the present invention is achieved like this, this elastic shock-absorbing device comprises at least one attaching screw and resilient cushion member, mounting bracket, electric vacuum pump body, described attaching screw is connected with electric vacuum pump body through the centre hole on the inner cylinder of resilient cushion member, an end face on the inner cylinder of resilient cushion member is contacted with the screw cap on attaching screw, and another end face contacts with electric vacuum pump body, thereby resilient cushion member is fixed on electric vacuum pump body; The ring support that described mounting bracket is installed in the out cylinder of resilient cushion member is installed in groove, and mounting bracket does not directly contact with electric vacuum pump body.
Described attaching screw is made up of upper end screw cap, middle cushion blocking linkage section and lower end vacuum pump body linkage section three parts.
Described resilient cushion member is made of elastomeric material, form by the inner cylinder with centre hole with the out cylinder of ring support mounting groove and with thin-walled coupling link three parts of reinforced rib, between described inner cylinder and out cylinder two cylinders, be connected and form thin-walled suspended structure by the thin-walled coupling link with reinforced rib, the elevation profile of described resilient cushion member is two " work " word shapes.
The present invention has the following advantages and good effect:
1), the present invention improves traditional connection mode.Between electric vacuum pump body and mounting bracket, increase resilient cushion member.Screw cap end contact on resilient cushion member on an end face and the attaching screw of inner cylinder, other end contacts with electric vacuum pump body.Attaching screw is connected with electric vacuum pump body through the centre hole on the inner cylinder of resilient cushion member, thereby resilient cushion member is fixed on electric vacuum pump body.Mounting bracket snaps in the annular mounting bracket groove in the out cylinder of cushion blocking.Mounting bracket does not directly contact with vacuum pump body, and like this, electric vacuum pump is just suspended on support by resilient cushion member.
2), because resilient cushion member of the present invention adopts elastomeric material and thin-walled suspended structure, therefore, in the time that electric vacuum pump turns round, resilient cushion member consumes vibration energy by the elastic deformation of material and thin-walled suspended structure, reduces significantly the vibration energy being delivered on support.
3), effectively reduced the vibration energy being delivered on support after adopting elastic shock-absorbing device of the present invention, while having met electric vacuum pump for automobile as vacuum source to travelling comfort requirement.
