초록 ▼

The track tension of a tracked vehicle is actively controlled by a track tensioner system that is positioned behind or within an idler wheel of a tracked vehicle. The system employs no exposed hydraulic line and is operable to default to a passive tensioning mode in the event of a system failure. Th

대표청구항 ▼

1. A track tensioner system comprising: an actuator;a valve;a fluid pump in fluid communication with the actuator;a fluid tank in fluid communication with the actuator; andan accumulator in fluid communication with the actuator;wherein, the fluid pump, the fluid tank, and the accumulator are positioned within an idler wheel. 2. The system of claim 1 wherein a drive gear of the idler wheel is configured to rotate a gear of the fluid pump. 3. The system of claim 1 wherein the fluid communication is through fluid flow paths formed within a manifold. 4. The system of claim 1 wherein the fluid communication is through fluid flow paths formed exclusively within a manifold. 5. The system of claim 1 wherein the valve is a poppet valve. 6. The system of claim 1 further comprising a controller. 7. A track tensioner system comprising; an actuator;a fluid pump in fluid communication with the actuator through a pump flow path;a fluid tank in fluid communication with the actuator through a tank return flow path;an accumulator in fluid communication with the actuator through an accumulator flow path; anda manifold through which at least the actuator flow path, the tank return flow path, and the accumulator flow path are formed;wherein the fluid pump, the fluid tank, and the accumulator are positioned within an idler wheel. 8. The system of claim 7 wherein the actuator is connected directly to the manifold. 9. The system of claim 7 further comprising a poppet valve. 10. The system of claim 7 further comprising a controller. 11. The system of claim 7 wherein the accumulator is formed within the manifold. 12. A track tensioner system comprising: an actuator;a fluid pump in fluid communication with the actuator through a pump flow path;a fluid tank in fluid communication with the actuator through a tank return flow path;an accumulator in fluid communication with the actuator through an accumulator flow path; anda manifold positioned within an idler wheel through which at least one of the actuator flow path, the tank return flow path, and the accumulator flow path is formed. 13. The system of claim 12 wherein a drive gear of the idler wheel is configured to rotate a gear of the fluid pump. 14. The system of claim 12 wherein the fluid pump, the fluid tank, and the accumulator are positioned within an idler wheel. 15. The system of claim 12 further comprising a poppet valve. 16. The system of claim 12 further comprising a controller. 17. The system of claim 12 wherein the accumulator is formed within the manifold. 18. The system of claim 12 wherein the actuator is connected directly to the manifold.
