Resonant Power Generation Hydraulic Drive Method and Device for Electric Vehicle Based on Leverage Effect

Abstract

The invention relates to a driving method and structure of resonant power generation of electric vehicles, and belongs to the field of automobiles. The hydraulic driving method of resonant power generation of the electric vehicles based on the leverage effect comprises the following steps that a generator is arranged on a hollow heavy weight supporting plate, a gear is arranged on the center shaftof the generator, the single side of the gear is meshed with a straight rack, and the straight rack is driven by a piston rod of a driven hydraulic cylinder of a hydraulic system group composed of pistons with different diameters and provided with the leverage effect to drive the central shaft of the generator to rotate, the hydraulic system group further includes a driving hydraulic cylinder arranged on a vehicle axle and a non-throttling pressure differential hydraulic circuit connected with one or more hydraulic cylinders, and a piston rod of the driving hydraulic cylinder is connected with a vehicle body bottom plate; and the vibration force of the sprung vehicle body is transmitted through the hydraulic circuit and the hydraulic cylinder and transformed into the driving force for rotating the generator. The hydraulic driving method uses hydraulic pressure to transmit vibration force to drive the resonant power generation of the electric vehicles, and the matching and cushioning of a resonant power generating device and a vehicle chassis structure are optimized.
