Problems solved by technology
[0004] However, the current shock absorber, in addition to the non-adjustable internal damping force, lacks the necessary flow-blocking components when the internal oil flows, resulting in poor damping effect, and cannot effectively cooperate with the shock-absorbing spring to achieve the shock-absorbing operation of the car.

The invention discloses an double-drum oil damping shock absorber for an automobile. The double-drum oil damping shock absorber comprises a fixed base, a piston rod, a piston head, a working cylinder,an anti-collision cylinder barrel, annular damping plates, a damping spring and a mounting end blocking cover. The double-drum oil damping shock absorber is characterized in that the fixed base is connected with one end of the piston rod, the bottom end of the piston rod penetrates through a shaft hole in the middle of an integrated oil seal base and then is arranged in an oil storage inner cavity in the working cylinder, the multiple annular damping plates are arranged in the portion, below the piston head, in the oil storage inner cavity, damping holes are formed in the annular damping plates, and the anti-collision cylinder barrel is sleeved with the damping spring; and when the annular damping plates are collided or extruded by the piston head, the annular damping plates deform alongthe damping holes, the staggered damping holes deform by force, the adjacent annular damping plates make contact with each other, the damping holes of the adjacent annular damping plates are preventedfrom communicating, by means of the closed damping holes, oil flow is avoided, damping force is formed, movement of the piston head can be retarded, thus, effective damping shock absorption is formed, and shock absorption operation is achieved together in cooperation with the damping spring.
Description
technical field [0001] The invention relates to a shock absorber, in particular to a double-tube oil damping shock absorber for automobiles. Background technique [0002] The main function of the shock absorber is to alleviate and attenuate the vibration and impact encountered by the vehicle during driving, to ensure the comfort, stability and safety of the rider, and to improve the stability and service life of the vehicle. [0003] At present, the internal damping force of the shock absorber used in the vehicle has been determined at the beginning of the design, so that the damping force of the shock absorber cannot be adjusted. Shock absorbers are usually automotive shock absorbers composed of dampers, shock absorbing springs and connectors. They have the functions of alleviating body vibration, improving driving comfort, transmitting various reaction forces, improving wheel grounding, and improving driving safety. Among them, the damper plays the role of easing the vibr...
