Problems solved by technology

The resistance to the piston is determined by the size of the damping hole, and once the damping hole is formed, its size cannot be changed, which leads to the inability to adjust the damping of the shock absorber.

Abstract

The invention discloses a damper with an automatic damping adjusting function, which belongs to the field of dampers. The damper comprises a cylinder body and a piston rod, wherein the inner wall of the cylinder body at least comprises a first cavity and a second cavity of which the diameters are different; a first piston and a second piston are connected in the first cavity in a sliding way; a third piston is connected to the second cavity in a sliding way; damping holes are formed in the first piston and the third piston; a first ventilation hole is formed in the first piston; a second ventilation hole is formed in the second piston; the projections of the damping hole formed in the first piston and the second ventilation hole formed in the second piston intersect with each other; an elastic component is arranged between the first piston and the second piston; the second piston is connected with the third piston through a connecting rod; and the piston rod is arranged on the first piston.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a shock absorber with automatic damping adjustment. Background technique [0002] 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. 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. Shock absorbers rely on damping force to dampen spring jump. If the damping force is too small, the vehicle body will jump up and down, and if the damping force is too large, there will be too much resistance, which will prevent the spring from working normally. [0003] The traditional shock absorber mainly includes a cylinder body, a piston is arranged in the cylinder body, a piston rod is fixed on the piston, a damping hole is also...
