Problems solved by technology

These types of shock absorbers are complex in structure, require an additional electronic control system, have high technical content, and are expensive. They are usually used in a small number of high-end off-road vehicles and high-end cars, and cannot be widely used in ordinary cars.
[0003] There is also a shock absorber structure that adopts manual adjustment, which is adjusted by a hollow rod outside the piston rod. This structure is more complicated, difficult to produce and process, and usually cannot meet the use requirements due to the limitation of installation space.

Abstract

The invention relates to an adjustable damping shock absorber. The shock absorber can be suitable for various vehicle suspensions or seats by manually adjusting damping. The adjustable damping shock absorber comprises a hoisting ring, a work cylinder, an oil storage cylinder, a middle cylinder, a guide base, an oil seal, a piston rod, a bottom valve assembly and a piston assembly. The adjustable damping shock absorber is characterized by further comprising a valve body, a valve element and a rotary arm, the valve body is assembled on the oil storage cylinder, the valve element and the rotary arm are assembled together, and the rotating action of the rotary arm is controlled by a driver. The shock absorber is simple and reliable in structure and low in cost, the damping force of the shock absorber can be easily adjusted according to the requirements of the driver, and therefore the vehicle comfort is improved.

Description

technical field [0001] The invention relates to a shock absorber, in particular to an adjustable damping shock absorber, which can change the damping through manual adjustment, and is suitable for various vehicle suspensions or seats. Background technique [0002] The vehicle's requirements for the damping strength of the shock absorber will change with changes in driving conditions such as load and road conditions. When the driving conditions change, if the damping force of the shock absorber cannot be adjusted accordingly, the damping effect will be unsatisfactory, seriously affecting the comfort of the vehicle. Now, with the continuous improvement of the technology of various shock absorber manufacturers and the needs of users, there are already a variety of shock absorbers with adjustable damping force on the market. These shock absorbers that can adjust the damping force usually use magneto-rheological, current Variable or electromagnetic valve technology, in which the...
