Abstract

A motor vehicle is provided. The motor vehicle comprises a vehicle body, a front wheel, a rear wheel and a tilting mechanism. The front wheel, the rear wheel and the tilting mechanism are disposed on the vehicle body. The tilting mechanism comprises a first compensation unit, a first arm, a first wheel, a second compensation unit, a second arm, a second wheel, at least one pipe and a fluid. The first arm is connected to the first compensation unit, and the first wheel. The second arm is connected to the second compensation unit, and the second wheel. The pipe connects the first compensation unit to the second compensation unit. The fluid flows in the first compensation unit, the second compensation unit and the pipe, wherein when the motor vehicle tilts, an extension length of the first compensation unit equals to a compression length of the second compensation unit.

Claims

1. A motor vehicle, comprising:

a vehicle body;

a front wheel, disposed on the vehicle body;

a rear wheel, disposed on the vehicle body; and

a tilting mechanism, disposed on the vehicle body, comprising;

a first compensation unit;

a first arm, connected to the first compensation unit;

a first wheel, connected to the first arm;

a second compensation unit;

a second arm, connected to the second compensation unit;

a second wheel, connected to the second arm;

at least one pipe, connecting the first compensation unit to the second compensation unit;

a throttle valve, disposed on the pipe; and

a fluid, flowing in the first compensation unit, the second compensation unit and the pipe, wherein when the motor vehicle tilts, an extension length of the first compensation unit equals to a compression length of the second compensation unit.

2. The motor vehicle as claimed in claim 1, wherein the first compensation unit and the second compensation unit are air cylinders.

3. The motor vehicle as claimed in claim 1, wherein the first compensation unit and the second compensation unit are oil cylinders.

4. The motor vehicle as claimed in claim 1, wherein the tilting mechanism further comprises a fixing frame, and the fixing frame is connected to the first compensation unit and the second compensation unit.

5. The motor vehicle as claimed in claim 1, wherein the tilting mechanism further comprises a fixing shaft, and the fixing shaft is connected to the first arm and the second arm.

6. The motor vehicle as claimed in claim 5, wherein the fixing shaft extends parallel to rotation shafts of the first wheel and the second wheel, and the fixing shaft comprises a central point, and the central point is located between two ends of the fixing shaft.

7. The motor vehicle as claimed in claim 6, wherein the fixing shaft comprises a post, the first arm comprises a compensation groove, the post is perpendicular to the fixing shaft, the fixing shaft rotates relative to the first arm to slide the post in the compensation groove, and the compensation groove is curved.

8. The motor vehicle as claimed in claim 7, wherein the compensation groove comprises a first groove end, a second groove end and a groove center, the distance between the first groove end and the central point is greater than the distance between the groove center and the central point, and when the motor vehicle tilts toward the first wheel, the post slides from the groove center to the first groove end.

9. The motor vehicle as claimed in claim 6, wherein the tilting mechanism further comprises an elastic compensation element, and the elastic compensation element is disposed between the first wheel and the first arm, and when the motor vehicle tilts, the elastic compensation element is compressed to keep the distance between the first wheel and the second wheel on the road unchanged.

10. The motor vehicle as claimed in claim 9, wherein the elastic compensation element is a compression spring.

11. A tilting mechanism for disposed on a vehicle body, comprising:

a first compensation unit;

a first arm, connected to the first compensation unit;

a first wheel, connected to the first arm;

a second compensation unit;

a second arm, connected to the second compensation unit;

a second wheel, connected to the second arm;

at least one pipe, connecting the first compensation unit to the second compensation unit;

a throttle valve, disposed on the pipe; and

a fluid, flowing in the first compensation unit, the second compensation unit and the pipe, wherein when the motor vehicle tilts, an extension length of the first compensation unit equals to a compression length of the second compensation unit.

12. The tilting mechanism as claimed in claim 11, wherein the first compensation unit and the second compensation unit are air cylinders.

13. The tilting mechanism as claimed in claim 11, wherein the first compensation unit and the second compensation unit are oil cylinders.

14. The tilting mechanism as claimed in claim 11, wherein the tilting mechanism further comprises a fixing frame, and the fixing frame is connected to the first compensation unit and the second compensation unit.

15. The tilting mechanism as claimed in claim 11, wherein the tilting mechanism further comprises a fixing shaft, and the fixing shaft is connected to the first arm and the second arm.

16. The tilting mechanism as claimed in claim 15, wherein the fixing shaft extends parallel to rotation shafts of the first wheel and the second wheel, and the fixing shaft comprises a central point, and the central point is located between two ends of the fixing shaft.

17. The tilting mechanism as claimed in claim 16, wherein the fixing shaft comprises a post, the first arm comprises a compensation groove, the post is perpendicular to the fixing shaft, the fixing shaft rotates relative to the first arm to slide the post in the compensation groove, and the compensation groove is curved.

18. The tilting mechanism as claimed in claim 17, wherein the compensation groove comprises a first groove end, a second groove end and a groove center, the distance between the first groove end and the central point is greater than the distance between the groove center and the central point, and when the motor vehicle tilts toward the first wheel, the post slides from the groove center to the first groove end.

19. The tilting mechanism as claimed in claim 16, wherein the tilting mechanism further comprises an elastic compensation element, and the elastic compensation element is disposed between the first wheel and the first arm, and when the motor vehicle tilts, the elastic compensation element is compressed to keep the distance between the first wheel and the second wheel on the road unchanged.

20. The tilting mechanism as claimed in claim 19, wherein the elastic compensation element is a compression spring.
