摘要： Off-highway trucks generally rely on a suspension system which employs a plurality of gas-over-liquid type struts. These struts are critical to proper operation of the vehicle such that a single collapsed strut can have serious manifestations in structural damage, tire wear, and payload monitor accuracy. These consequences can be mitigated by an accurate and reliable strut monitor. Pressure type sensors are disposed on each of the struts and their pressure is monitored during three critical phases of operation. These phases include static, loading, and roading modes and each mode requires a distinct method for detecting a collapsing strut. The presence of a collapsing strut, detected by any of the three methods, is communicated to the vehicle operator whereby operation can be immediately suspended. The system avoids the serious consequences of vehicle operation with a collapsed strut by providing the operator with immediate and positive feedback on the condition of the struts.

摘要： A method and system for controlling a transmission in a work machine is provided. The output of a hydrostatic transmission having a source of pressurized fluid is combined with the output of a mechanical transmission having at least one engaged clutch. An operational speed of an engine that provides an input to both the hydrostatic transmission and the mechanical transmission is sensed. The at least one clutch of the mechanical transmission is disengaged and the displacement of the source of pressurized fluid is modified when the operational speed of the engine drops below a stall limit. The disengagement of the at least one clutch and the modification of the displacement of the source of pressurized fluid allow the operational speed of the engine to rise above the stall limit.
