Description

Double-cylinder pillar type automobile shock absorber

Technical Field

The utility model relates to the technical field of shock absorbers, in particular to a double-cylinder strut type automobile shock absorber.

Background

The shock absorber is used for inhibiting vibration and impact from road surface when the spring rebounds after absorbing the vibration. The damping device is widely used for automobiles, and is used for accelerating the damping of the vibration of the frames and the automobile bodies so as to improve the running smoothness of the automobiles. While the shock absorbing spring can filter the shock of road surface when passing over uneven road surface, the spring itself can reciprocate, and the shock absorber is used to restrain the spring from jumping. In the compression stroke (the axle and the frame are close to each other), the damping force of the shock absorber is small so as to fully exert the elastic action of the elastic element and alleviate the impact. At this time, the elastic member plays a main role. In the extension stroke of the suspension (the axle and the frame are far away from each other), the damping force of the shock absorber should be large, and the shock is rapidly absorbed. When the relative speed between the axle (or wheel) and the axle is too high, the shock absorber is required to automatically increase the liquid flow rate, so that the damping force is always kept within a certain limit, and the excessive impact load is avoided.

Most of the existing shock absorbers are single-way, namely, only have one telescopic stroke, and when in rebound, the potential energy is larger, the rebound force is larger, so that the vibration of the vehicle is more severe, and therefore, the double-cylinder strut type automobile shock absorber is provided.

Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and features in the embodiments may be combined with each other.

A dual tube strut type shock absorber for a vehicle according to some embodiments of the present utility model is described below with reference to the accompanying drawings.

Embodiment one:

referring to fig. 1-3, the dual-cylinder strut type automobile shock absorber provided by the utility model comprises an outer sleeve 110, a bottom plate 120 connected to the bottom of the outer sleeve 110, elastic steel bars 130 fixed on the bottom plate 120, rubber rings 140 assembled above the inner wall of the outer sleeve 110 and outer ring magnets 150 fixed below the inner wall of the outer sleeve 110, wherein the number of the elastic steel bars 130 is two, the inner layer mechanism 200 comprises an embedded cylinder 210 inserted into the outer sleeve 110, an inner ring magnet 220 connected to the bottom of the embedded cylinder 210, a connecting rod 280 inserted into the embedded cylinder 210, a buffer plate 230 connected to the bottom end of the connecting rod 280, a cylinder column 240 fixed at the bottom of the buffer plate 230, and a cylinder 250 sleeved at the bottom end of the cylinder column 240, wherein the inner ring magnet 220 and the outer ring magnets 150 are mutually adsorbed, the inner ring magnets 220 are not contacted with each other, the buffer plate 230 is circular, and the diameter value of the buffer plate 230 is equal to the inner diameter value of the embedded cylinder 210.
