Abstract

To provide a suspension system that can efficiently lay out a shock absorber and various accessories in a fuel cell electric vehicle where a fuel cell is mounted in the vicinity of a floor portion of the body. In a suspension system of a fuel cell electric vehicle provided with a fuel cell mounted in the vicinity of a floor portion of the body, a motor is provided for generating a driving force of a vehicle based upon electric power supplied from the fuel cell. A motor unit is supported by a body frame so that the motor unit can be rocked for housing the motor and a shock absorber provided between the motor unit and the body frame. The shock absorber is arranged under the fuel cell.

Claims (42)

1. A suspension system in a fuel cell electric vehicle provided with a fuel cell mounted in the vicinity of a floor portion of a body, a motor for generating a driving force for the vehicle based upon electric power supplied from the fuel cell, a motor unit supported by a body frame so that the motor unit can be rocked for housing the motor and a shock absorber provided between the motor unit and the body frame, wherein:

the shock absorber is arranged under the fuel cell, and

further comprising:

a dilutor for diluting gaseous hydrogen not consumed in the fuel cell, wherein:

the dilutor is arranged below the fuel cell; and

the shock absorber is arranged between a lower end of the fuel cell and a lower end of the dilutor.

2. The suspension system in a fuel cell electric vehicle according to claim 1 , comprising:

a shock absorber rod, one end side of which is coupled to the motor unit, and another end side of which extends toward a front of the vehicle; and

a shock absorber arm which is coupled to the another end side of the shock absorber rod, an upside of which is supported by the body frame so that the shock absorber arm can be rocked, and a downside of which is coupled to a front end of the shock absorber, wherein:

a rear end of the shock absorber is coupled to the body frame.

3. The suspension system in a fuel cell electric vehicle according to claim 2 , wherein a front end of the shock absorber is located in front of the fuel cell.

4. The suspension system in a fuel cell electric vehicle according to claim 2 , comprising:

a pipe for exhaust coupled to the dilutor, wherein:

the pipe for exhaust is arranged on a side of the shock absorber; and

the pipe for exhaust is arranged so that it is overlapped with the shock absorber when the body frame is viewed from the side.

5. The suspension system in a fuel cell electric vehicle according to claim 1 , wherein a front end of the shock absorber is located in front of the fuel cell.

6. The suspension system in a fuel cell electric vehicle according to claim 1 , comprising:

a pipe for exhaust coupled to the dilutor, wherein:

the pipe for exhaust is arranged on a side of the shock absorber; and

the pipe for exhaust is arranged so that it is overlapped with the shock absorber when the body frame is viewed from the side.

7. A suspension system in a fuel cell electric vehicle comprising:

a fuel cell mounted adjacent to a floor portion of a vehicle;

a motor unit supported by a body frame wherein the motor unit can be pivoted relative to the body frame; and

a shock absorber provided between the motor unit and the body frame, wherein the shock absorber is arranged under the fuel cell, and

further comprising:

a shock absorber rod, one end side of which is coupled to the motor unit, and another end side of which extends toward a front of the vehicle; and

a shock absorber arm which is coupled to another end side of the shock absorber rod, an upside of which is supported by the body frame so that the shock absorber arm can be rocked, and a downside of which is coupled to a front end of the shock absorber, wherein:

the rear end of the shock absorber is coupled to the body frame.

8. The suspension system in a fuel cell electric vehicle according to claim 7 , comprising:

a dilutor for diluting gaseous hydrogen not consumed in the fuel cell, wherein:

the dilutor is arranged below the fuel cell; and

the shock absorber is arranged between a lower end of the fuel cell and a lower end of the dilutor.

9. The suspension system in a fuel cell electric vehicle according to claim 8 , wherein a front end of the shock absorber is located in front of the fuel cell.

10. The suspension system in a fuel cell electric vehicle according to claim 8 , comprising:

a pipe for exhaust coupled to the dilutor, wherein:

the pipe for exhaust is arranged on a side of the shock absorber; and

the pipe for exhaust is arranged so that it is overlapped with the shock absorber when the body frame is viewed from the side.

11. The suspension system in a fuel cell electric vehicle according to claim 7 , wherein a front end of the shock absorber is located in front of the fuel cell.

12. The suspension system in a fuel cell electric vehicle according to claim 7 , comprising:

a pipe for exhaust coupled to a dilutor, wherein:

the pipe for exhaust is arranged on the side of the shock absorber; and

the pipe for exhaust is arranged so that it is overlapped with the shock absorber when the body frame is viewed from the side.
