摘要： A wheel tractor scraper having a rear wheel drive assist, the wheel tractor scraper includes a tractor portion pivotally coupled to a rear scraper portion, the rear scraper portion having a bowl for hauling material and a fluid powered work tool configured to assist in loading the bowl, the work tool powered by a fluid pump connected to a fluid operated work tool motor. The rear wheel drive assist includes a fluid operated drive motor coupled to the rear wheels of the machine, a diverter valve having a first position at which fluid flow is delivered from the pump to the work tool motor and a second position at which fluid flow is delivered from the pump to the drive motor, and a controller being configured to control the diverter valve to engage the rear wheel drive assist. The machine may be operated by engaging the pump and work tool motor, and then actuating the diverter valve to the second position to divert flow from the work tool motor to the drive motor.

摘要： A method of controlling a pump and motor system having at least one of a variable displacement pump and a variable displacement motor. The method may comprise providing an engine drivingly coupled to a primary load and a secondary load, the secondary load being driven by the pump and motor system. The method may also comprise sensing a change in engine speed in response to a change in the primary load. The method may further comprise changing the engine speed to compensate for the primary load change. The method may further comprise changing a displacement of the at least one variable displacement pump and the variable displacement motor to maintain a constant secondary load.

摘要： A machine control system may include an input receiving portion configured to receive torque inputs related to a hydrostatic transmission. The input receiving portion may also receive an operator request for actuating the hydrostatic transmission. The machine control system may also include a processor configured to determine a factor based at least in part on the torque inputs, for adjusting the operator request. The processor may also be configured to determine a command for actuating the hydrostatic transmission based on the adjusted operator request, such that a torque load to be exerted on a power source by the hydrostatic transmission is within a desired range. The machine control system may further include an output sending portion configured to send the command to the hydrostatic transmission.

摘要： A hydrostatically driven vehicle has an engine operating a variable displacement propel pump, a displacement of which can vary based on an angle of a rotating swashplate, such that a fluid flow impelled by the pump transfers power to at least one propel motor rotating a wheel of the vehicle. An electronic controller of the vehicle senses an operating parameter of the system, for example, the angle of the rotating swashplate or the direction and speed of rotation of the propel motor with a sensor to yield an actual signal, and relays the actual signal to an electronic controller. The controller determines a desired angle for the rotating swashplate based on the control signal, and compares it to the actual signal from the sensor. Motion of the vehicle is stalled when the angle signal differs from the desired angle by a predetermined extent and for a predetermined period.
