Oil-gas active interconnection energy feedback suspension

Abstract

The present invention provides an oil-pneumatic active interconnection energy-feeding suspension, which includes a first oil-pneumatic suspension A and a second oil-pneumatic suspension B, and the oil outlets of the first oil-pneumatic suspension A and the second oil-pneumatic suspension B pass through The rectifier bridge is connected, the output end of the rectifier bridge is connected with the hydraulic motor, the hydraulic motor is connected with the generator, and the generator is connected with the battery circuit. When the road provides a certain excitation to the suspension, the first oil-pneumatic suspension A and the second oil-pneumatic suspension B generate liquid interaction, and the liquid always flows through the hydraulic motor in one direction through the rectifier bridge, and the hydraulic motor rotates to drive the generator to generate electricity , and store the generated electric energy in the battery through the battery circuit. Therefore, the vibration energy of the suspension can be effectively recovered while meeting the vehicle performance, and the system can adjust the hydraulic motor speed by controlling the MOS tube controller in the battery circuit, so as to actively control the designed suspension and improve the smooth performance and handling stability of the vehicle performance.

Description

technical field [0001] The patent of the present invention relates to an oil-gas active interconnection energy-feeding suspension, in particular to an oil-air interconnection suspension system with an energy-feeding unit, which can actively control the designed suspension through circuit adjustment, and improve vehicle smoothness and handling stability . Background technique [0002] The chassis suspension system of large-scale engineering vehicles mostly adopts oil-pneumatic suspension, and oil-pneumatic suspension is generally divided into two types: independent type and connected type; connected type oil-pneumatic suspension system can reduce the natural frequency of the body and facilitate vehicle attitude adjustment, and Compared with the independent oil-pneumatic suspension system, its vehicle roll stiffness is greater, the vehicle driving stability is better, and it is more widely used on large engineering vehicles. At the same time, the roads of large-scale engineer...

Problems solved by technology

At the same time, the roads of large-scale engineering vehicles are complicated, and the bumps of the road surface as well as the acceleration, deceleration, and steering of the vehicle will cause the sprung mass (the mass of the part above the suspension, such as the body, frame, cargo, passengers, etc.) to be different from the unsprung mass. Relative motion occurs between the load mass (the mass of the part below the suspension, such as the axle, wheels, etc.), and the impact load is buffered by the elastic elements in the car suspension, but the vibration still exists
