Novel car shock absorber

Abstract

The invention discloses a novel car shock absorber which comprises a buffer connected with a car through connection disc. The buffer comprises a buffer shell provided with a piston cavity, a buffer piston shaft is installed in the piston cavity in a sliding manner, a damping barrel is arranged in the piston cavity, a reset spring is arranged in the damping barrel, and a lubricating oil inlet channel is formed in the buffer shell; an oil storage groove is formed in the side, provided with the lubricating oil inlet channel, of the buffer shell, a plurality of through holes are formed in the damping barrel, the piston cavity and the oil storage groove are communicated through the through holes, and an lubricating oil outlet channel is formed in the side, far away from the lubricating oil inlet channel of the buffer shell; and a damping channel for communicating the two sides of a piston of the buffer piston shaft is formed in the piston of the buffer piston shaft. According to the shock absorber assembly, through the unique structural design and the further improvement of a dustproof cover, many beneficial effects are obtained, and the good application prospect and industrial production potential are achieved in the field of car manufacturing and the field of shock absorbers.

Description

technical field [0001] The invention relates to a shock absorber, more particularly to a novel automobile shock absorber, belonging to the technical field of shock absorbers. Background technique [0002] In order to quickly attenuate the vibration of the frame and the body and improve the ride comfort and comfort of the car, the car suspension system is generally equipped with a shock absorber. The shock absorber is a vulnerable part during the use of the car. The shock absorber Whether it works well or not will directly affect the driving stability of the car and the life of other parts, so the shock absorber should always be in good working condition. [0003] The shock absorber is mainly used 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).

Problems solved by technology

[0009] CN105370790A discloses an automobile shock absorber, which includes: a support plate, a piston rod, a piston, a cylinder, a first return spring and a permanent magnet, and the support plate, piston rod and piston are 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 is arranged in the cylinder body, the support plate is arranged above the upper surface of the cylinder body, and the piston rod The upper end passes through the upper part of the cylinder, the first return spring is sleeved on the piston rod, and one end is connected to the support plate, and the other end is fixed on the top of the cylinder, which overcomes the reduction in the prior art. After a long-term use of the shock absorber, the shock absorption effect will become worse, the rebound ability of the shock absorber will easily fail, and the service life will be short, so as to provide a long-term shock absorber with good shock absorption effect during long-term use, and the shock absorber rebounds Strong elastic capacity and long service life automobile shock absorber
