Embodiment Construction

[0016] The load-sensing variable damping system for air suspension, as shown in Figure 1, consists of an air spring, an auxiliary air chamber and a load-sensing variable damping valve. The specific structure of the load-sensing variable damping valve is shown in Figure 2. The A chamber of the load-sensing variable damping valve communicates with the air spring, and the B chamber communicates with the auxiliary air chamber. Load-sensing variable damping valve consists of damping valve core 3, sealing ring 4, one-way valve return spring 5, one-way valve 6, valve body 7, one-way valve port 8, sealing ring 9, control spring 10 and valve cover 11 .

[0017] The sealing ring 4 in the load-sensing damping valve can be replaced by a sealing diaphragm, as shown in Figure 3, the advantage of this replacement is that it can reduce the friction of the sealing ring and improve the sensitivity of load control.

Abstract

The invention relates to a load sensing variable damping or a controllable load sensing variable damping shock mitigation system, which is adaptable for air or oil gas hanger brackets (including semi-active hanger brackets) for various vehicles with the damping varying with loading and driving conditions. The shock mitigation system arranges a loading sensing variable damping valve or a controllable load sensing variable damping with a special structure on an air or oil gas hanger bracket, thereby realizing enabling a flowing damp of air or oil gas to automatically change along with loading, or enabling the flowing damp of air or oil gas to automatically change along with loading or to be controlled by signals emitted by a switch or a running state sensor of a driver, thereby realizing the adjustment to the damp. Compared with the internal resistance shock absorber of the traditional air or oil gas hanger bracket, the shock mitigation system has the advantages that the damp not only can automatically change along with the loading, but also can be adjusted along with external controlling signals ( driver's intention or moving state), compared with the air hanger bracket which is usually equipped with an independent shock absorber, the shock mitigation system has the advantages of simple structure, low cost and long service life.

Description

technical field [0001] The invention relates to the internal damping control technology of fluid suspension. Utilizing the technology does not need to add an independent shock absorber part and can realize the control of suspension damping. It is suitable for air and oil-pneumatic suspensions (including semi-active suspensions) of various vehicles whose damping needs to change with driving conditions. Background technique [0002] The requirements of the vehicle for the damping strength of the shock absorption system will change with the load, road conditions, vehicle speed, longitudinal acceleration, lateral acceleration, vertical acceleration and other driving conditions, as well as the driver's personality. When the driving conditions change, or there is a need to adjust the damping, the damping system usually cannot adjust the damping strength accordingly, and it is difficult to achieve a satisfactory damping effect, which will affect the comfort of the vehicle.
