Abstract

An endless belt tensioner system adapted to dynamically apply a tensioning force on a ground-contacting endless belt of a vehicle is provided, the tensioning force being managed to prevent the endless belt to disengage from an operating configuration when the suspension is actuated. A vehicle and a method of use thereof are also provided.

Claims

1. An endless belt tensioner system comprising:

a tensioner module adapted to physically apply tension to an endless belt of a vehicle; and

a tensioner management module adapted to manage the tensioner module,

wherein the endless belt tensioner system dynamically manages the tension in the endless belt to allow appropriate suspension movement and to prevent the endless belt to disengage from an operating configuration when the suspension is actuated.

2. The endless belt of claim 1, wherein the tension in the endless belt is based at least in part on the speed of the vehicle.

3. The endless belt of claim 1, wherein the tensioner module includes an hydraulic cylinder actuatable to manage the tension in the endless belt, the hydraulic cylinder being adapted to be operatively located outside a periphery of the endless belt.

4. The endless belt of claim 3, wherein the tensioner module includes at least one lever operatively connected between the hydraulic cylinder and at least one endless belt contacting wheel adapted to be operatively disposed within the periphery of the endless belt.

5. The endless belt of claim 1, wherein the tensioner module is adapted to individually manage tension in two separate endless belts operatively suspending the vehicle.

6. The endless belt of claim 1, wherein, when the endless belt tensioner system is installed on a vehicle, the tension in the endless belt is adapted to be substantially proportional to an endless belt drive force propelling the vehicle.

7. The endless belt of claim 1, wherein, when the endless belt tensioner system is installed on the vehicle, the tension in the endless belt is adapted to be managed by the tensioner module when the vehicle moves forward and when the vehicle moves rearward.

8. A vehicle including an endless belt tensioner system, the endless belt tensioner system comprising:

a tensioner module adapted to physically apply tension to an endless belt of a vehicle; and

a tensioner management module adapted to manage the tensioner module,

wherein the endless belt tensioner system dynamically manages the tension in the endless belt to allow appropriate suspension movement and to prevent the endless belt to disengage from an operating configuration when the suspension is actuated.

9. The vehicle of claim 8, wherein the tension in the endless belt is based at least in part on the speed of the vehicle.

10. The vehicle of claim 8, wherein the tensioner module includes a hydraulic cylinder actuatable to manage the tension in the endless belt, the hydraulic cylinder being adapted to be operatively located outside a periphery of the endless belt.

11. The vehicle of claim 10, wherein the tensioner module includes at least one lever operatively connected between the hydraulic cylinder and at least one endless belt contacting wheel adapted to be operatively disposed within the periphery of the endless belt.

12. The vehicle of claim 8, wherein the tensioner module is adapted to individually manage tension in two separate endless belts operatively suspending the vehicle.

13. The vehicle of claim 8, wherein, when the endless belt tensioner system is installed on a vehicle, the tension in the endless belt is adapted to be substantially proportional to an endless belt drive force propelling the vehicle.

14. The vehicle of claim 8, wherein, when the endless belt tensioner system is installed on a vehicle, the tension in the endless belt is adapted to be managed by the tensioner module when the vehicle moves forward and when the vehicle moves rearward.

15. A method of managing a ground-contacting endless belt tension installed on a vehicle, the method comprising:

sensing a vehicle behavior; and

dynamically adjusting the tension in the ground-contacting endless belt based, at least in part, on the sensed vehicle behavior while allowing sufficient slack in the endless belt so as to allow appropriate suspension movement and to prevent disengagement of the endless belt from its operating configuration on the vehicle.

16. The method of claim 15 wherein the appropriate suspension movement corresponds to allowing maximum suspension travel.

17. The method of claim 15, wherein adjusting tension in the ground-contacting endless belt is made on a basis of an actuation of a hydraulic cylinder disposed outside a periphery of the ground-contacting endless belt.

18. The method of claim 17, wherein the actuation of the hydraulic cylinder further actuates at least one lever operatively connected between the hydraulic cylinder and at least one endless belt contacting wheel adapted to be operatively disposed within the periphery of the endless belt.

19. The method of claim 17, further sensing a drive direction of the vehicle.

20. The method of claim 17, further separately adjusting the tension in a plurality of ground-contacting endless belts on the vehicle.
