Abstract
A vehicle height control system includes an arm including a first end portion connected to a vehicle body and a second end portion coupled to a wheel, a bearing unit fixed to the vehicle body, a crank coupled to the bearing unit, a push rod including a first end portion connected to the crank and a second end portion connected to the arm, and a spring reaction force variable device coupled to the bearing unit and configured to vary reaction force applied to the crank.
Claims18
A vehicle height control system comprising:
- an arm including a first end portion connected to a vehicle body and a second end portion coupled to a wheel;
- a bearing unit fixed to the vehicle body;
- a crank coupled to the bearing unit;
- a push rod including a first end portion connected to the crank and a second end portion connected to the arm;
- and
- a spring reaction force variable device coupled to the bearing unit and configured to vary reaction force applied to the crank,
- wherein the spring reaction force variable device further includes:
- a motor configured to provide torque;
- a clutch unit connected to an output shaft of the motor;
- a reducer located at an output end portion of the clutch unit and coupled to the crank;
- and
- a spring portion coupled to the reducer, and
- wherein reaction torque of the spring portion is varied by driving the motor.
