Description
Technical field
The utility model relates to the vibration insulating system of automobile, particularly relates to a kind of oil gas for heavy card operator cabin combination vibration damper.
Background technique
Heavily card Vibration damping of the driver's cab system mainly makes the intercropping elasticity of vehicle frame and the operator cabin heavily blocked contact, and bears and transmits normal load, relaxes and resists the impact caused by uneven road surface.At present, the primary resilient element heavily in card Vibration damping of the driver's cab system is that the coaxial integrated oil gas combined by rubber air spring and dydraulic shock absorber combines vibration damper, its compact structure, is convenient to install.Rubber air spring and dydraulic shock absorber realize damping by a shared air chamber to be changed with associating of rigidity, utilizes the mobility of the compressibility of air dielectric and fluid medium to relax impact between vehicle frame and operator cabin and high vibration.But the oil gas combination vibration damper used in current heavily card Vibration damping of the driver's cab system, its rubber air spring is when filling exhaust, the whole outside being exposed at pneumatic spring of the gas joint used, when filling exhaust, gas joint is easily touched down or breaks, and causes filling exhaust and cannot carrying out smoothly of pneumatic spring.
Summary of the invention
Technical problem to be solved in the utility model is to provide and a kind ofly ensures to fill that exhaust carries out smoothly for the oil gas combination vibration damper of heavy card operator cabin.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of combination of the oil gas for heavy card operator cabin vibration damper, comprise rubber air spring and dydraulic shock absorber, described rubber air spring comprises nylon piston, air bag and end cap, one end of described air bag is fixedly connected with described nylon piston, the other end of described air bag is fixedly connected with described end cap, described dydraulic shock absorber is coaxially through described rubber air spring, described dydraulic shock absorber comprises cylinder body and piston rod, described nylon piston coaxial stuffing box gland is located on described cylinder body, described cylinder body is fixedly installed position limiting convex ring, described position limiting convex ring is positioned at the rear side of described nylon piston, described piston rod co-axial seal is through described end cap, described upper cover of piston rod is provided with buffer stopper, the end of described piston rod is bolted with connecting rod, described connecting rod is against on the exterior edge face of described end cap, the rear end of described nylon piston is provided with fills exhaust port, described filling in exhaust port is bolted with gas joint, between described nylon piston and described cylinder body, two seal rings are side by side provided with between described end cap and described piston rod.
The other end of described air bag is set on described end cap, and the part of described end cap and described balloon contacts is provided with outside thread, is arranged with locking ring outside the other end of described air bag, and the other end of described air bag and described end bracket enclosed are fixed.
The outer end of described cylinder body is fixedly installed the connecting bushing for being connected with vehicle frame or operator cabin respectively with the outer end of described connecting rod.
Described air bag forms by three layers, and outer and internal layer is the good neoprene packing layer of tightness, and mesosphere is the nylon cord fabrics framework layer of high strength.
Compared with prior art, the utility model has the advantages that because the gas joint for being connected with tracheae is arranged in nylon piston, gas joint can be prevented to be touched down when filling exhaust or to break, ensure that rubber air spring fills carrying out smoothly of exhaust; And be provided with two seal rings side by side between nylon piston and cylinder body, between end cap and piston rod, its good sealing effect.
