Improved shock attenuation device

Abstract

The invention discloses an improved shock attenuation device which comprises a damper shell, a piston seat, a spring seat II welded on the damper shell, and a piston rod fixedly installed on the piston seat, wherein a movable baffle plate is arranged between the upper end of the shell and a piston head; an air damping hole is formed in the movable baffle plate; an air chamber is formed above the movable baffle plate; an elastic layer is embedded inside the damper shell; two sides of the piston head are matched with the elastic layer; a W-shaped piece is installed on the piston rod; and two sides of the W-shaped piece are matched with the elastic layer. By installing the W-shaped piece on the piston rod, the problem of deviation of the axis of the piston rod and the problem of friction in the running process can be relieved; due to a buffer layer and the embedded elastic layer, the leakage of oil liquide and the impact of the W-shaped piece to the bottom during the movement of the piston are effectively reduced, the use effect is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of safety equipment manufacture, in particular to an improved shock absorbing device on a motor vehicle. Background technique [0002] With the improvement of the quality of life, motor vehicles such as cars and motorcycles are gradually generalized. On these vehicles, the shock absorber is a very widely used device. [0003] In the usual shock absorbing device, the piston rod is directly matched with the housing, which will generate noise during driving. What is more serious is that due to the direct fit, the wear is relatively large, which leads to oil leakage, which not only pollutes other components, but may even life-threatening. In addition, due to the strong adsorption of dust and other substances during driving, dust and other substances will be adsorbed around the piston rod when the piston rod reciprocates, and then brought into the oil, thereby polluting the oil and affecting the shock absorption effect. ...

Problems solved by technology

[0003] In the usual shock absorbing device, the piston rod is directly matched with the housing, which will generate noise during driving. What is more serious is that due to the direct fit, the wear is relatively large, which leads to oil leakage, which not only pollutes other components, but may even life-threatening

In addition, due to the strong adsorption of dust and other substances during driving, dust and other substances will be adsorbed around the piston rod when the piston rod reciprocates, and then brought into the oil, thereby polluting the oil and affecting the shock absorption effect. In severe cases, the damping hole can even be blocked, so that the shock absorption effect cannot be achieved.
