Abstract

To achieve a small and low power consumption suspension, which can be installed in a vehicle, such as a personal mobility vehicle, there is provided a vehicle suspension system including: a suspension that is connected to a vehicle body and a shaft mounted to wheels; an actuator that includes an output for vertically moving a suspension position of the suspension on the basis of inclination angle information of the vehicle; and a self-weight support mechanism that acts on the actuator to support vehicle weight. The self-weight support mechanism is composed of a spring mounted to the actuator, the actuator, and a link mechanism connected the suspension and the actuator.

Claims (36)

1. A vehicle suspension system for a vehicle that has a vehicle body supported by wheels and is moved by driving the wheels, comprising:

a suspension that is connected to the vehicle body and a shaft mounted to the wheels;

an actuator that includes an output for vertically moving a suspension position of the suspension on the basis of inclination angle information of the vehicle; and

a self-weight support mechanism that acts on the actuator to support vehicle weight, wherein

the self-weight support mechanism is composed of a spring that is directly connected to the actuator, and a link mechanism that is connected to the suspension and that is directly connected to the actuator.

2. The vehicle suspension system according to claim 1 , further comprising:

a support link connected to an intermediate portion of the link mechanism and one end of the vehicle body,

wherein the actuator moves over a guide that is perpendicular to a direction of gravity.

3. The vehicle suspension system according to claim 1 , wherein the actuator is movably embedded in a frame and the spring is mounted to one end of the frame and the actuator.

4. The vehicle suspension system according to claim 1 , wherein:

one end of the link mechanism and the actuator are connected by a wire;

the actuator and the spring are connected by an end of the wire; and

the actuator moves over a guide to thereby act on the suspension through the link mechanism connected to the wire.

5. The vehicle suspension system according to claim 1 , wherein:

the self-weight support mechanism is connected to both the vehicle body and the suspension.

6. A vehicle suspension system for a vehicle that has a vehicle body supported by wheels and is moved by driving the wheels, comprising:

a suspension that is connected to a shaft mounted to the wheels;

an actuator that includes an output for vertically moving a suspension position of the suspension on the basis of inclination angle information of the vehicle; and

a self-weight support mechanism that acts on the actuator to support vehicle weight between the vehicle body and the suspension, wherein

the self-weight support mechanism is composed of a spring that is directly connected to the actuator, and a link mechanism that is connected to the suspension and that is directly connected to the actuator.

7. The vehicle suspension system according to claim 6 , further comprising:

a support link connected to an intermediate portion of the link mechanism and one end of the vehicle body,

wherein the actuator moves over a guide that is perpendicular to a direction of gravity.

8. The vehicle suspension system according to claim 6 , wherein the actuator is movably embedded in a frame and the spring is mounted to one end of the frame and the actuator.

9. The vehicle suspension system according to claim 6 , wherein:

one end of the link mechanism and the actuator are connected by a wire;

the actuator and the spring are connected by an end of the wire; and

the actuator moves over a guide to thereby act on the suspension through the link mechanism connected to the wire.

10. The vehicle suspension system according to claim 6 , wherein:

the self-weight support mechanism is connected to both the vehicle body and the suspension.

11. A vehicle suspension system for a vehicle that has a vehicle body supported by wheels and is moved by driving the wheels, comprising:

a suspension that is connected to the vehicle body and a shaft mounted to the wheels;

an actuator that includes an output for vertically moving a suspension position of the suspension on the basis of inclination angle information of the vehicle; and

a self-weight support mechanism that acts on the actuator to support vehicle weight, wherein

the self-weight support mechanism is composed of a spring mounted to the actuator, and a link mechanism that is connected to the suspension and the actuator, and

the actuator is movably embedded in a frame and the spring is mounted to one end of the frame and the actuator.
