Problems solved by technology

[0005] The purpose of the present invention is to provide a damping control method of a shock absorber, which solves the problem of the complicated pipeline connection of the interconnected air shock absorber module in the prior art, and only relies on the inertial force of the vehicle to realize the adjustment of the air pressure inside the air shock absorber. To achieve active control, the adjusted damping force may not necessarily meet the problem of vehicle operating conditions; the purpose of the present invention is also to provide a voltage-controlled variable damping system; the purpose of the present invention is to provide a vehicle

Embodiment Construction

[0030] The embodiments of the present invention will be further described below in conjunction with the drawings.

[0031] Embodiment 1 of the vehicle of the present invention, such as Figure 2 to Figure 4 As shown, the vehicle includes an axle (not shown in the figure) and a suspension structure connected to the axle. The suspension structure includes a guide rod 10, an air spring 12, and a pressure-controlled variable-vibration damping system. The damping system includes an air damper 1, which is connected to an air spring 12 through an upper mounting bracket 13, and is connected to a guide rod 10 through a lower mounting bracket 14.

[0032] The air shock absorber 1 adopts an air shock absorber in the prior art. The air shock absorber 1 has a working cavity. When the working cavity is filled with gas, the internal pressure of the entire working cavity increases, and the air shock absorber The stiffness of 1 increases; when the gas is discharged from the working chamber, the pr...

Abstract

The invention relates to a damping control method of a shock absorber, a pressure controlled variable-damping shock absorption system and a vehicle. The damping control method of the shock absorber includes the following steps that 1, the working conditions of the vehicle are detected through a sensor; 2, an automatic control device controls a control valve connected with a working cavity of the air shock absorber to be switched on or off according to the detected working conditions of the vehicle to achieve inflation and deflation of the working cavity, the pressure of the working cavity is changed through inflation and deflation of the working cavity, and damping in the air shock absorber is changed. The working conditions of the vehicle are detected through the sensor, the automatic control device controls the control valve to be switched on or off according to the detected working conditions of the vehicle to achieve inflation and deflation of the working cavity, then the damping of the air shock absorber is changed, active control is achieved, and adjusted damping force can meet various working conditions of the vehicle.

Description

Technical field [0001] The invention relates to a damping control method of a shock absorber, a pressure-controlled variable damping damping system and a vehicle. Background technique [0002] During the driving of the vehicle, due to the fact that there are more uneven roads and bumpy roads such as speed bumps, the vehicle will have a greater sense of impact and severe bumps when passing on a poor road. The passengers are extremely uncomfortable. The passengers complained. In order to solve these problems, one of the solutions is to reduce the stiffness of the suspension and reduce the damping force of the shock absorber to obtain a more comfortable suspension performance. However, due to the reduction of the stiffness and damping of the suspension, it also brings insufficient control. The sense of roll is large, which leads to the problem of reduced driving safety. The ride comfort and handling stability of the vehicle are both improved, which has become a difficult problem t...
