Automobile spring shock absorber

Abstract

The invention discloses an automobile spring shock absorber which comprises a shock absorption oil cylinder, a supporting arm is movably arranged at the lower end of the interior of the shock absorption oil cylinder in a penetrating mode, a piston is fixedly arranged at the upper end of the supporting arm, the piston is movably arranged in the shock absorption oil cylinder in a clamped mode, and a connecting block is fixedly arranged at the upper end of the shock absorption oil cylinder. A first fixing block is fixedly arranged at the upper end of the connecting block, a first mounting bearing is fixedly arranged in the middle of the inner side of the connecting block, a second fixing block is fixedly arranged at the lower end of the supporting arm, a second mounting bearing is fixedly arranged in the middle of the inner side of the second fixing block, and the damping oil cylinder is filled with buffering oil. A fixing ring is fixedly arranged in the middle of the outer side surface of the supporting arm. The device is good in using effect, and damping force can be automatically controlled for damping buffering according to the jolting amplitude and speed when a vehicle jolts during running through the passive adjusting damping mechanism.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to an automobile spring shock absorber. Background technique [0002] The shock absorber is used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road. It is widely used in automobiles to accelerate the attenuation of frame and body vibrations and improve the ride comfort of automobiles. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jumping. [0003] However, the current shock absorbers have two kinds of shock absorbers whose damping strength can be adjusted by themselves when they are in use. One is the airbag shock absorber and this kind of shock absorber is easy to be damaged, the airbag is easy to age, corrode, and is easy to be damaged by sharp objects. The possibility of...

Problems solved by technology

[0003] However, the current shock absorbers have two kinds of shock absorbers whose damping strength can be adjusted by themselves when they are in use. One is the airbag shock absorber and this kind of shock absorber is easy to be damaged, the airbag is easy to age, corrode, and is easy to be damaged by sharp objects. The possibility of scratching, the other is the electromagnetic shock absorber, and this kind of shock absorber needs high voltage to generate strong magnetism when it is used, so it often needs to be equipped with complex electronic control systems and voltage transformation systems, with many structures and easy damage. And lack a kind of novel simple spring shock absorber with active adjustment damping function to solve the above problems at present
