Problems solved by technology

[0003] Ordinary shock absorbers generally have constant cushioning force characteristics, so low cushioning force characteristics can improve driving comfort, but cannot ensure vehicle stability
On the contrary, high cushioning force characteristics can maintain the stable posture of the vehicle, but lead to a decrease in driving comfort
Thus, conventional shock absorbers cannot control the cushioning force characteristics in response to changes in road conditions or vehicle attitude

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: see figure 1 , Embodiment 1, a shock absorber, including a shock absorber 1 and a first support spring 2, the first support spring 2 is sleeved on the outside of the shock absorber 1, and one end of the first support spring 2 is fixed on the shock absorber On the outer wall of the shock absorber 1, the other end is arranged on the spring cover 3, and at least a second adjustment spring 4 is sleeved on the shock absorber 1, and one end of the second adjustment spring 4 is also fixed on the shock absorber 1 On the outer wall, the other end is arranged on the spring cover 3, and the second adjustment spring 4 is in a stretched state when the shock absorber 1 is in a balanced position. When the shock absorber is in use, since the first support spring 2 is initially in a compressed state, the force generated by the first support spring 2 is always...

Abstract

The invention discloses a damping device, which comprises a damper and a first supporting spring, wherein the first supporting spring is sleeved on the outer side of the damper, one end of the first supporting spring is fixed on the outer side wall of the damper, the other end is arranged on a spring gland bush, the damper is at least provided with a second adjusting spring in a sleeving manner, one end of the second adjusting spring is also fixed on the outer side wall of the damper, the other end of the second adjusting spring is arranged on the spring gland bush, and the second adjusting spring stays at a stretching state when the damper is arranged on a balance position. The first supporting spring initially stays at a compression state, so that the force produced by the first supporting spring always faces towards the outer side of the first supporting spring; the second adjusting spring initially stays at the stretching state, the second adjusting spring firstly applies the force towards the inner side of the spring in the compression process of the damping device, then when the second adjusting spring is compressed to the original length, the elastic force direction is changed, an effect for changing the characteristics of the buffering force can be realized, and the driving stability can be improved.

Description

technical field [0001] The invention relates to a damping device for damping vibration transmitted to a vehicle according to road conditions. Background technique [0002] Usually, the vehicle is equipped with a suspension system, which enhances driving comfort by buffering the shock or vibration transmitted from the ground to the axle during driving. One of the components that constitutes the suspension system is a shock absorber. The shock absorber is provided between the axle and the body. The shock absorber consists of a cylinder and a piston rod that reciprocates inside the cylinder. The cylinder is filled with working fluid, such as gas or oil, so that the working fluid is moved by a piston valve, which is fixed to one end of the piston rod, to generate a damping force. [0003] Ordinary shock absorbers generally have constant cushioning force characteristics, so low cushioning force characteristics can improve driving comfort, but cannot ensure vehicle stability.
