Abstract
A reversible drive belt system comprises a drive belt, a forward direction drive motor, and a reverse direction hydraulic drive motor. A belt tensioning element has a force applied to it by a first tensioning system and a second tensioning system in the form of a hydraulic cylinder. When the drive system is operated in the reverse direction, an input hydraulic pressure to the hydraulic cylinder is controlled in dependence on a load on the hydraulic motor.
Claims8
A reversible drive belt system, comprising:
- a drive belt;
- a drive motor arrangement comprising a forward direction drive motor and a reverse direction drive motor, wherein the reverse direction drive motor comprises a hydraulic drive motor;
- a belt tensioning element;
- a first tensioning system for applying force to the belt tensioning element to apply a tensioning force to the drive belt;
- and
- a second tensioning system for applying force to the belt tensioning element to apply a tensioning force to the drive belt, the second tensioning element comprising a hydraulic cylinder;
- wherein the hydraulic drive motor comprises a hydraulic pressure supply line;
- wherein the hydraulic cylinder is actuated by an input hydraulic pressure;
- and
- wherein when the drive system is operated in the reverse direction, the input hydraulic pressure is coupled to the hydraulic pressure supply line of the hydraulic motor and the input hydraulic pressure to the hydraulic cylinder is controlled in dependence on a load on the hydraulic motor wherein the input hydraulic pressure is proportional to the load on the hydraulic motor.
