Abstract
An apparatus for adjusting vehicle height is disclosed. The apparatus for adjusting vehicle height, may include a pump configured to supply or recover a fluid; and an actuator mounted between a chassis and a vehicle body of a vehicle, the actuator being configured to receive the fluid from the pump to raise the vehicle body and increase the vehicle height, or to lower the vehicle body and decrease the vehicle height as the fluid is recovered by the pump.
Claims19
An apparatus for adjusting vehicle height, comprising:
- a pump configured to supply or recover a fluid;
- and
- an actuator mounted between a chassis and a vehicle body of a vehicle, the actuator being configured to receive the fluid from the pump to raise the vehicle body and increase the vehicle height, or to lower the vehicle body and decrease the vehicle height as the fluid is recovered by the pump,
- wherein the pump comprises:
- a motor configured to rotate in a forward or reverse direction;
- a spindle configured to rotate in the forward or reverse direction according to the forward or reverse rotation of the motor;
- a spindle nut through which the spindle is coupled, the spindle nut being configured to move forward when the spindle rotates in the forward direction and to move backward when the spindle rotates in the reverse direction;
- and
- a piston mounted in contact with the spindle nut and configured to move forward or backward together with the spindle nut.
An apparatus for adjusting vehicle height, comprising:
- a pump configured to supply or recover a fluid;
- and
- an actuator mounted between a chassis and a vehicle body of a vehicle, the actuator being configured to receive the fluid from the pump to raise the vehicle body and increase the vehicle height, or to lower the vehicle body and decrease the vehicle height as the fluid is recovered by the pump,
- wherein the actuator comprises:
- an outer tube having one open end;
- an inner tube inserted into the outer tube through the open end of the outer tube;
- and
- a fixed piston fixed to the outer tube and disposed inside the inner tube, the fixed piston and an inner wall of the inner tube together defining an actuating chamber.
An apparatus for adjusting vehicle height, comprising:
- a pump comprising a bidirectionally rotatable motor and a piston configured to move forward or backward within a pump chamber according to rotation of the motor, the piston being configured to pressurize fluid disposed in the pump chamber toward the outside or to draw fluid from the outside into the pump chamber;
- and
- an actuator mounted between a chassis and a vehicle body of a vehicle, the actuator being configured to receive the fluid from the pump to raise the vehicle body and increase the vehicle height, or to lower the vehicle body and decrease the vehicle height as the fluid is recovered by the pump,
- wherein the actuator comprises:
- an outer tube having one open end;
- an inner tube inserted into the outer tube through the open end of the outer tube;
- and
- a fixed piston fixed to the outer tube and disposed inside the inner tube, the fixed piston and an inner wall of the inner tube together defining an actuating chamber.
