A dual-cylinder oil damping shock absorber for automobiles

Abstract

The invention discloses a double-cylinder oil damping shock absorber for automobiles, comprising a fixed seat, a piston rod, a piston head, a working cylinder, an anti-collision cylinder, an annular damping plate, a shock-absorbing spring and a mounting end cover. The fixed seat is connected to one end of the piston rod, and the bottom end of the piston rod is arranged in the oil storage cavity inside the working cylinder after passing through the shaft hole in the middle of the integrated oil seal seat, and the oil storage cavity under the piston head is provided with an oil storage cavity. Several annular damping plates, the annular damping plate is provided with a damping hole, and the anti-collision cylinder is sleeved with a shock-absorbing spring; when the annular damping plate is hit or squeezed by the piston head, the annular damping plate is deformed along the direction of the damping hole, and the staggered The damping holes provided are deformed by force, and the adjacent annular damping plates want to contact and prevent the damping holes from communicating with each other. The closed damping holes prevent the flow of oil and form a damping force, which is conducive to slowing down the movement of the piston head, thereby forming an effective damping hole. Damping and shock absorption, and cooperate with shock-absorbing spring to realize shock-absorbing operation.

Description

technical field [0001] The present invention relates to a shock absorber, more particularly, to a double-cylinder oil damping shock absorber for automobiles. Background technique [0002] The main function of the shock absorber is to moderate and attenuate the vibration and shock encountered by the vehicle during driving, to ensure the comfort, stability and safety of the rider, thereby improving the stability and service life of the vehicle. [0003] The size of the internal damping force of the shock absorber currently 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. The shock absorber is usually composed of a damper, a shock absorber spring and a connecting piece for automobiles. It can alleviate the vibration of the body and improve the driving comfort, and transmit various reaction forces to improve the grounding of the wheels and improve the driving safety. Among them, the dampe...

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.
