Abstract

A track assembly for traction of a tracked vehicle, such as an agricultural vehicle, an industrial vehicle (e.g., a construction vehicle) or a military vehicle, is provided. The track assembly comprises a plurality of wheels which comprises a drive wheel and a plurality of roller wheels, as well as an elastomeric endless track disposed around the plurality of wheels for engaging the ground. A roller wheel may comprise a wheel body and a covering on the wheel body. The covering may comprise a lateral portion dimensioned to contact a drive/guide lug of the track. The roller wheels and the track may implement a self-alignment system of the track assembly. The track assembly may comprise a cooling system for transferring heat away from a roller wheel. The track assembly may comprise a lateral motion mechanism allowing a roller wheel to move widthwise in response to a side load.

First claim

The invention claimed is:

a track for engaging the ground; and
a plurality of wheels that includes a drive wheel for driving the track around the wheels;

wherein the track assembly comprises a temperature sensor configured to sense a temperature of a component of the track assembly.

2. The track assembly of claim 1 , wherein the temperature sensor is configured to convey the temperature of the component of the track assembly via a wireless link.

3. The track assembly of claim 1 , wherein the temperature sensor is configured to convey the temperature of the component of the track assembly via a wired link.

4. The track assembly of claim 1 , wherein the temperature sensor is configured to convey the temperature of the component of the track assembly to a processing device configured to perform an operation related to the vehicle based on the temperature of the component of the track assembly.

5. The track assembly of claim 4 , wherein the temperature sensor is configured to convey the temperature of the component of the track assembly to the processing device via a wireless link.

6. The track assembly of claim 4 , wherein the temperature sensor is configured to convey the temperature of the component of the track assembly to the processing device via a wired link.

7. The track assembly of claim 4 , wherein the operation related to the vehicle includes an operation controlling an aspect of the vehicle based on the temperature of the component of the track assembly.

8. The track assembly of claim 7 , wherein the operation controlling the aspect of the vehicle is based on the temperature of the component of the track assembly and a speed of the vehicle.

9. The track assembly of claim 7 , comprising a cooling system configured to transfer heat away from at least part of the track assembly, wherein the aspect of the vehicle includes the cooling system.

10. The track assembly of claim 9 , wherein the cooling system comprises a fan and the operation controlling the cooling system includes an operation controlling the fan.

11. The track assembly of claim 4 , wherein the processing device is configured to perform the operation related to the vehicle when the temperature of the component of the track assembly reaches a threshold.

12. The track assembly of claim 1 , comprising a frame supporting respective ones of the wheels, wherein the component of the track assembly is movable relative to the frame as the drive wheel drives the track.

13. The track assembly of claim 12 , wherein the component of the track assembly is a given one of the wheels.
