The utility model relates to a hydraulic shock absorber

The utility model relates to a hydraulic shock absorber, wherein the component is provided with a dust cover, retractable dust cover, piston seal assembly, the damper piston rod guide seat, piston rod, cylinder, piston, guide tubing, foot valve assembly, storage tank components, ball rubber joints. Spherical rubber dust cover assembly and welding joints, retractable dust cover mounted on the piston rod seal assembly, piston rod seal assembly is mounted on the piston rod guide seat, damper, lead pipe installed in the seat the piston rod guide, piston and threaded rod locking connection, the bottom valve assembly is mounted in the bottom of the storage tank, storage tank components and spherical rubber joint welding.

Oil shock absorbers are locomotives vehicle

Oil shock absorbers are locomotives (diesel locomotive, electric locomotive) vehicle, light rail vehicles and motorways large passenger bogies (axles) a suspension system, an important secondary suspension damping member means it is by stretching the compression piston reciprocating movement formed hydraulic damper vibration damping force to achieve the purpose of having a good damping damping effect and flexible damping effect, improving the locomotive, the smooth operation of the vehicle speed, and comfort, safety critical components .
