Automobile shock absorber assembly

Abstract

The invention discloses an automobile shock absorber assembly which comprises a buffer shell connected with a suspension. The buffer shell is provided with a piston guide cavity; a center guide shaft is slidably installed in the piston guide cavity and connected with an automobile adapter plate; a guide cylinder is arranged inside the piston guide cavity; a guide piston is arranged on a piston of the center guide shaft; a reset spring is arranged inside the guide cylinder; a piston compression cavity communicating with the piston guide cavity is arranged inside the buffer shell; a compression spring is arranged at the end, extending into the buffer shell, of the center guide shaft; a gas energy storage cavity is arranged inside the buffer shell and communicating with the piston compression cavity; the gas energy storage cavity is arranged on a gas exhaust channel inside the buffer shell in a communicating mode; and a compression spring is arranged between the automobile adapter plate and the buffer shell. The automobile shock absorber assembly has many beneficial technical effects and has good application prospects and industrial production potentials in the automobile industrial field through the unique structural design and mutual matching.

Description

technical field [0001] The invention relates to a shock absorber, more particularly to an automobile shock absorber assembly, and belongs to the technical field of mechanical shock absorbers. Background technique [0002] In the automobile industry, in order to improve the comfort, it is necessary to quickly attenuate the vibration of the frame and the body, so as to improve the ride comfort and comfort of the car. To achieve such an effect and purpose, shock absorbers are generally installed on the automobile suspension system. [0003] The working principle of the shock absorber is to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface, and to counteract the torsional vibration of the crankshaft (that is, the phenomenon that the crankshaft is twisted by the impact force of the cylinder ignition), etc. Under the premise of affecting the overall performance of the car, it is an important research content in the field of...

Problems solved by technology

[0010] CN105370790A discloses an automobile shock absorber, which comprises: a support plate 1, a piston rod 2, a piston 3, a cylinder 9, a first return spring 4 and a permanent magnet 6, the support plate, the piston rod It is fixedly connected with the piston from top to bottom in sequence, the permanent magnet is arranged on the top of the cylinder body and is fixedly connected with the cylinder body, the piston 3 is arranged in the cylinder body, and the support plate is arranged on the upper surface of the cylinder body above, and the upper end of the piston rod passes through the upper part of the cylinder body, the first return spring is sleeved on the piston rod, and one end is connected with the support plate, and the other end is fixed on the cylinder body 8 The top end overcomes the problems that the shock absorber in the prior art will have poor shock absorption effect after long-term use, the rebound ability of the shock absorber is prone to failure, and the service life is short, thereby providing a shock absorption effect during long-term use. Good durability, strong resilience of the shock absorber, and long service life of the car shock absorber
