Abstract

The invention provides an interconnected variable volume air suspension and a control method thereof. The interconnected variable volume air suspension comprises an air spring, a hydraulic boosting device, a connecting rod mechanism and a hydraulic interconnection system; the air spring is provided with an accommodating chamber; the air spring is connected with the hydraulic boosting device; the hydraulic boosting device is connected with a frame of a vehicle through the connecting rod mechanism; the bottom of the connecting rod mechanism is connected with a suspension of the vehicle; the hydraulic boosting device pushes a slide block through reciprocating motion of a piston so that the slide block moves in a reciprocating manner under the pushing of high pressure oil in the hydraulic boosting device and high pressure gas in the accommodating chamber of the air spring; and an oil port of the hydraulic boosting device is connected with the hydraulic interconnection system. The inventionfurther provides the control method for the interconnected variable volume air suspension. According to the interconnected variable volume air suspension, the anti-deformation degree of the air spring can be effectively enhanced, the smoothness of the vehicle can be obviously improved, and the anti-roll capacity of the vehicle can be enhanced.

Description

technical field [0001] The invention relates to the technical field of vehicle air suspension, in particular to an interconnected variable volume air suspension and a control method thereof. Background technique [0002] The air spring utilizes the compressibility of the gas to achieve its elastic effect, and has the functions of buffering and vibration isolation. The stiffness of the air spring is one of the key components that affect the comfort of the car. In order to adapt the automobile air suspension to various complex working conditions of the vehicle, the stiffness characteristics and damping characteristics of the spring are changed by changing the volume of the air spring to improve the ride comfort and stability of the vehicle; the hydraulic interconnection system makes each other independent The unique suspension system cooperates with each other to improve the driving stability of the vehicle. [0003] Example: Vehicle Suspension System with Reservoir for Air S...
