Abstract
The utility model discloses an oil gas combination shock absorber for commercial car, including air spring and hydraulic damper, air spring includes piston, gasbag and top cap, and during hydraulic damper stretched into air spring, hydraulic damper included cylinder body and piston rod, the piston with the axle sleeve on the cylinder body and with the sealed fixed connection of cylinder body, the tip and the top cap coaxial sealing fixed connection of piston rod, the cover is equipped with the buffer block on the piston rod, characteristics are that the top cap is the tubbiness and is equipped with the cavity in and, form an additional air chamber behind the end seal fixed connection of top cap and piston rod, the advantage is owing to form an additional air chamber behind the end seal fixed connection of top cap and piston rod, constitutes two air chambers together with the air chamber that gasbag, piston formed, during the use, has improved the rigidity of oil gas combination shock absorber, has improved riding comfort, ride performance and the control stability of vehicle greatly, and its damping effect reaches the best.
Description
Technical field
The utility model relates to the elastic member in automobile suspension system, particularly relates to a kind of oil gas for commercial vehicle combination vibration damper.
Background technique
Generally use air spring vibration reduction system that the intercropping elasticity of vehicle frame and vehicle bridge is contacted in automobile, bear and transmit normal load, relax and resist the impact caused by uneven road surface.And the air spring vibration reduction system used in commercial vehicle is the coaxial integrated oil gas combined by rubber air spring and dydraulic shock absorber combines vibration damper, its integral rigidity and effectiveness in vibration suppression better than rubber air spring, but the structure of the oil gas combination vibration damper used in commercial vehicle at present makes its effectiveness in vibration suppression also cannot reach best.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of rigidity improving vibration damper, to reach the combination of the oil gas for the commercial vehicle vibration damper of best effectiveness in vibration suppression.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of combination of the oil gas for commercial vehicle vibration damper, comprise pneumatic spring and dydraulic shock absorber, described pneumatic spring comprises piston, air bag and top cover, one end of described air bag is fixedly connected with described piston, the other end of described air bag is fixedly connected with described top cover, described dydraulic shock absorber stretches in described pneumatic spring, described dydraulic shock absorber comprises cylinder body and piston rod, described piston coaxial to be enclosed within described cylinder body and to be fixedly connected with described cylinder body seal, the end of described piston rod is fixedly connected with described top cover co-axial seal, described upper cover of piston rod is provided with buffer stopper, described top cover be tubbiness and in be provided with cavity, described top cover is fixedly connected with rear formation one auxiliary chamber with the end part seal of described piston rod.
Clamp ring is provided with in the other end of described air bag, the outer surface of described clamp ring is provided with outside thread, it is outer and be provided with internal thread that one end that described top cover is connected with described air bag is enclosed within described air bag, under the acting in conjunction of the outside thread of described clamp ring and the internal thread of described top cover, described air bag and described top seal fixed; This linkage structure makes being connected firmly and good airproof performance of air bag and top cover.
Described piston and described cylinder body are welded and fixed.
The end winding support of described top cover is provided with flexible installing inner sleeve, and the end of described piston rod is fixedly connected with described flexible installing inner sleeve co-axial seal, when travelling at uneven road surface, can reduce the impact to oil gas combination vibration damper.
Described top cover is fixedly installed the turnover gas interface for assembling electronic equilibrium valve.
Compared with prior art, the utility model has the advantages that because top cover is fixedly connected with rear formation one auxiliary chamber with the end part seal of piston rod, two air chamber is formed together with the air chamber that air bag, piston are formed, during use, improve the rigidity of oil gas combination vibration damper, substantially increase the riding comfort of vehicle, run smoothness and control stability, its effectiveness in vibration suppression reaches best; Again owing to top cover being fixedly installed the turnover gas interface for assembling electronic equilibrium valve, it again as the interface of electronic equilibrium valve, improves the level of integration of general assembly both as pneumatic spring vent charge, is convenient to install.
