Abstract

In a vehicle of a type which does not bank a vehicle body at the time of turning, an inclination angle sensor is provided which receives the least influence of a centrifugal force at the time of turning. In a four-wheeled buggy that includes a vehicle body frame, four longitudinal wheels including front wheels and rear wheels are provided together with an engine, a fuel tank and a fuel pump. A steering shaft is connected to a steering handle with an inclination angle sensor arranged above a seat and being positioned in front of the steering shaft. Accordingly, the inclination angle sensor is hardly influenced by a centrifugal force at the time of turning.

Claims

1. An arrangement structure of an inclination angle sensor mounted on a vehicle which includes a frame, at least three wheels which are supported on the frame, and a steering shaft which is connected to a steering handle comprising:

an inclination angle sensor, said inclination angle sensor being arranged in front of the steering shaft and above an axis of a front wheel.

2. The arrangement structure of an inclination angle sensor according to claim 1, and further including a radiator and a reservoir tank, arranged behind the radiator, said inclination angle sensor being arranged behind the reservoir tank.

3. The arrangement structure of an inclination angle sensor according to claim 1, wherein the inclination angle sensor is mounted on a cross member which is arranged to extend between left and right sides of a vehicle body frame and supports an upper end of a front shock absorber of a front-wheel suspension.

4. The arrangement structure of an inclination angle sensor according to claim 1, wherein the inclination angle sensor is arranged in the vicinity of the center of turning for reducing the influence of centrifugal force on the inclination angle sensor.

5. The arrangement structure of an inclination angle sensor according to claim 1, wherein said frame includes front down frame members and a front portion of the lower frame with a cross member being disposed between the front down frame members at a position displaced upwardly relative to the lower frame and the inclination angle sensor is mounted adjacent to the cross member.

6. The arrangement structure of an inclination angle sensor according to claim 5, wherein the cross member is disposed at an intermediate portion of the front down frame members.

7. The arrangement structure of an inclination angle sensor according to claim 1, wherein the inclination angle sensor is concealed by a surface of the reservoir to prevent exhaust heat from the radiator from thermally damaging the inclination angle sensor.

8. The arrangement structure of an inclination angle sensor according to claim 6, wherein the cross member is approximately an inverse U-shape as viewed from the side with a lower portion of the cross member being welded to the front down frame members.

9. The arrangement structure of an inclination angle sensor according to claim 8, wherein the inclination angle sensor includes a float having a semicircular shape that is pivotally mounted on a swinging shaft mounting nut with a damper being provided for limiting the swinging movement of the float.

10. The arrangement structure according to claim 9, wherein the swinging shaft of the float is arranged substantially parallel to a longitudinal direction of the vehicle body.

15. The arrangement structure according to claim 1, wherein said frame includes front down frame members and a front portion of the lower frame with a cross member being disposed between the front down frame members at a position displaced upwardly relative to the lower frame and the inclination angle sensor is mounted adjacent to the cross member.

16. The arrangement structure according to claim 15, wherein the cross member is disposed at an intermediate portion of the front down frame members.

18. The arrangement structure according to claim 16, wherein the cross member is approximately an inverse U-shape as viewed from the side with a lower portion of the cross member being welded to the front down frame members.

19. The arrangement structure according to claim 18, wherein the inclination angle sensor includes a float having a semicircular shape that is pivotally mounted on a swinging shaft mounting nut with a damper being provided for limiting the swinging movement of the float.

20. The arrangement structure according to claim 19, wherein the swinging shaft of the float is arranged substantially parallel to a longitudinal direction of the vehicle body.

11. An arrangement structure comprising:

a frame of a vehicle;

an inclination angle sensor mounted on the frame; and

a steering shaft operatively connected to a steering handle;

said inclination angle sensor being positioned in front of the steering shaft and above an axis of a front wheel.

12. The arrangement structure according to claim 11, and further including a radiator and a reservoir tank, arranged behind the radiator, said inclination angle sensor being arranged behind the reservoir tank.

13. The arrangement structure according to claim 11, wherein the inclination angle sensor is mounted on a cross member which is arranged to extend between left and right sides of a vehicle body frame and supports an upper end of a front shock absorber of a front-wheel suspension.

14. The arrangement structure according to claim 11, wherein the inclination angle sensor is arranged in the vicinity of the center of turning for reducing the influence of centrifugal force on the inclination angle sensor.

17. The arrangement structure according to claim 11, wherein the inclination angle sensor is concealed by a surface of the reservoir to prevent exhaust heat from the radiator from thermally damaging the inclination angle sensor.
