Abstract
The utility model discloses an air bag device with a dustproof cover. The air bag device comprises a connecting base communicated with an oil pipe of a shock absorber. One end of the connecting base is sleeved with an air bag pipe, an air bag installation cavity is arranged in the air bag pipe, and one end, far away from the connecting base, of the air bag pipe, is provided with a sealing plate. The middle of the sealing plate is provided with an air hole, and a one-way inflation device is disposed in the air hole. One side, close to the air bag installation cavity, of the sealing plate is provided with an air bag. The dustproof cover covers the outside of one side, away from the air bag installation cavity, of the sealing plate. Due to the fact that one end, far away from the connecting base, of the air bag pipe is provided with the dustproof cover, the air bag device can effectively prevent dust, water and other impurities from entering. Therefore, parts in the air bag pipe are prevented from being polluted by dust and other impurities, and the inside of the air bag pipe keeps clean.
Description
Technical field
The utility model relates to the automobile absorber technical field, is specifically related to a kind of air bag device with dust cover.
Background technique
Concussion when vibration damper, vibration damper are mainly used to suppress bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, although the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Its working principle is that the piston in the vibration damper moves up and down when relative movement occurring when vibrations between vehicle frame or vehicle body and vehicle bridge, and the fluid in the vibration damper chamber just flows in another chamber through different holes from a chamber repeatedly.The at this moment friction between hole wall and fluid and the intermolecular interior friction of fluid forms damping force to vibrations, and making the thump Conversion of Energy is fluid heat energy, absorbed by vibration damper to be dispersed in the atmosphere again.
Vibration damper generally is connected with air bag device at an end of oil pocket, can regulate the overall volume of liquid oils in the oil pocket, can adjust the oil pressure of liquid oils in the oil pocket simultaneously.Existing this air bag device generally by direct one-body molded connecting base on the outer side wall of vibration damper oil pipe, is installed in air bag device on the connecting base again.The air bag of the air bag device of existing vibration damper is generally with one-way valve etc., the exposed setting such as hush panel, and the impurity such as dust are easy to enter, and make air bag can not keep clean.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, the utility model provides a kind of air bag device with dust cover of dustproof and waterproof.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of air bag device with dust cover, comprise the connecting base that is communicated with setting with the vibration damper oil pipe, one end of described connecting base is arranged with airsac tube, be provided with the air bag installation cavity in the described airsac tube, described airsac tube is provided with hush panel away from an end of connecting base, the middle part of described hush panel is provided with gas port, be provided with unidirectional inflator in the described gas port, described hush panel is equipped with air bag by a side of air bag installation cavity, and the side outer cover that described hush panel deviates from the air bag installation cavity is covered with dust cover.
As preferably, described dust cover comprises the lid body, week of described lid body, described lid body embedded described airsac tube away from the port of an end of connecting base along being provided with the installation flange, the setting that offsets of the madial wall of described installation flange and described airsac tube.After adopting above-mentioned preferred version, arranging of flange is installed makes the installation of dust cover and airsac tube more firm.
As preferably, the outer side wall of described installation flange is provided with the dust cover seal groove, is provided with dust cover O RunddichtringO in the described dust cover seal groove.After adopting above-mentioned preferred version, can increase the sealing between dust cover and the airsac tube, avoid entering of the liquid impurities such as water droplet.
As preferably, described connecting base is provided with the connecting base flange that can embed airsac tube, and the outer side wall of described connecting base flange is provided with the connecting base seal groove, is provided with connecting base O RunddichtringO in the described connecting base seal groove.After adopting above-mentioned preferred version, the sealability between connecting base and the airsac tube is better.
As preferably, described hush panel comprises the hush panel body, the week of described hush panel body is along being provided with the hush panel flange that extends towards the airsac tube lateral direction, the setting that offsets of the madial wall of described hush panel flange and described airsac tube, the outer wall of described hush panel flange is provided with the sealing draw-in groove, described Air sac cover is located on the hush panel flange, on the described air bag madial wall with sealing draw-in groove corresponding position be provided with the air bag that seals draw-in groove and engage setting in fixture block.After adopting above-mentioned preferred version, the installation between air bag and the hush panel is more firm.
Your device of robbing with dust cover of the present utility model arranges dust cover at airsac tube away from an end of connecting base, can effectively prevent entering of the impurity such as dust, water, thereby the pollution that the component of avoiding airsac tube inside are received the impurity such as dust, the cleaning of maintenance airsac tube inside.
