If a smaller damping force is needed, corresponding current and voltage are output, so that the motor 10 generates a torque in the same direction as the forced rotation direction, and the torque acts on the hydraulic motor blade 9 and the hydraulic motor main body 11, so that the hydraulic motor blade 9 and the hydraulic motor main body rotate at an accelerated speed, the flow of oil flowing through the core structural component is improved, and the damping force is further reduced.

If a large damping force is needed, corresponding current and voltage are output, so that the motor 10 generates a torque opposite to the forced rotation direction, and the torque acts on the hydraulic motor blades 9 and the hydraulic motor main body 11, so that the hydraulic motor blades and the hydraulic motor main body rotate to decelerate, the flow of oil flowing through the core structural component is reduced, and the damping force is further improved.

The energy feedback function and the damping force adjusting function of the device are executed based on an integral control strategy, and specific control is carried out based on actual vehicle requirements, so that the capacity self-feedback of the system and the adjustment of the damping force of the shock absorber are realized.
