Oil-gas active interconnection energy feedback suspension

Abstract

The invention provides an oil-gas active interconnection energy feedback suspension which comprises a first oil-gas suspension body A and a second oil-gas suspension body B. Oil outlets of the first oil-gas suspension body A and the second oil-gas suspension body B are connected through a rectifier bridge. The output end of the rectifier bridge is connected with a hydraulic motor. The hydraulic motor is connected with a power generator. The power generator is connected with a battery circuit. When certain excitation is supplied to the suspension by a road surface, liquid interaction is generated by the first oil-gas suspension body A and the second oil-gas suspension body B, liquid flows through the hydraulic motor in one direction all the time through the rectifier bridge, the hydraulic motor rotates to drive the power generator to generate power, and generated electric energy is stored in a battery through the battery circuit. Therefore, suspension vibration energy is effectively recovered while the requirement for the vehicle performance is met, in a system, an MOS transistor controller in the battery circuit can be controlled so as to adjust the rotation speed of the hydraulic motor, so that the designed suspension is actively controlled, and the smoothness performance and the operation stability performance of a vehicle are improved.

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
