Abstract

The invention discloses a variable stroke damping curve shock absorber which comprises a cylinder bottom and an oil seal. A work cylinder is fixedly installed at the upper end of the cylinder bottom,a cylinder cover is fixedly installed at the upper end of the work cylinder, a piston connecting rod is arranged in the oil seal and the cylinder cover in a penetrating mode, one side of the cylinderbottom is movably provided with an oil storage cylinder base, the upper end of the oil storage cylinder base is fixedly provided with an oil storage cylinder, a special-shaped rod is fixedly installedabove the cylinder bottom, the bottom end of the piston connecting rod is sleeved with a piston, the upper surface of the piston is fixedly provided with a small stop block, one side of the small stop block is fixedly provided with a spring, and one end of the spring is fixedly provided with a fan-shaped valve. The mechanical structure is simple, no electronic element is arranged, machining is convenient, the cost is low, any compression stroke-damping curve and any stretching stroke-damping curve can be customized on one shock absorber only by adjusting the shapes of a throttling hole and the special-shaped rod.

Description

technical field

[0001] The invention relates to a shock absorber, in particular to a variable stroke damping curve 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 surface. It is widely used in automobiles to accelerate the attenuation of the vibration of the frame and the body to improve the ride comfort of the car. 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 jump.

[0003] Ordinary hydraulic shock absorbers and self-adjusting damping shock absorbers cannot set stroke-damping curves for different compression and tension conditions. It cannot solve the contradiction between the comfort and sportiness of the car. The structure of the electromagnetic shock absorber is complicated and the co...
