UTILITY VEHICLE HORSEPOWER MANAGEMENT |
摘要 |
Disclosed are horsepower management systems and methods for use on power machines (100) with an engine (130) that powers a drive system. An engine speed control device (220) controls the engine speed. A variable displacement drive pump (205) controlled by a displacement control member (215) provides pressurized fluid to a drive motor (214). A control system (200) communicates with the engine speed control device and the pump displacement control member. The control system includes a user input device (230) and a command lever (210) rotatably coupled to the displacement control member and capable of receiving the user input. The command lever provides a signal to the engine speed control device in response to the user input. The command lever also commands a given displacement via the displacement control member subject to load forces on the hydrostatic pump transmitted to a limiting mechanism (240) coupled to the command lever and the displacement control member (215). |
