    摘要: A hydrostatic driveline has a power source and a hydrostatic pump in driving engagement with the power source; a primary driveline shaft in driving engagement with the power source. The driveline also has a first transmission portion and a second transmission portion in driving engagement with the first transmission portion. A hydrostatic motor is in fluid communication with the hydrostatic pump and is in driving engagement with the first transmission portion. A vehicle output is in driving engagement with the second transmission portion. The primary driveline shaft is also in driving engagement with the second transmission portion. The hydrostatic driveline may be operated in a hydrostatic mode or in a direct drive mode using the primary driveline shaft and the second transmission portion.

    摘要: A self-propelled off-road agricultural vehicle is provided with a hydraulic propel circuit protection system. The hydraulic propel circuit protection system reduces extreme pressure buildup from the motors when the pumps and/or motors are rapidly deactivated. The hydraulic propel circuit protection system may include a propel manifold with integral valving and an accumulator to protect a propel circuit of the self-propelled off-road agricultural vehicle. External relief valves which may be integrated into the propel manifold may limit the high pressure condition on the outlet of the motors to a level that prevents damage to the hydraulic motors and the accumulator provides supplemental flow and thus prevents the extremely low pressure condition from occurring at either side of the motors.

    摘要: A mixer drum driving apparatus includes a liquid-pressure motor that drives the mixer drum to rotate, a liquid-pressure pump that is driven by a motive force of an engine and supplies working liquid to the liquid-pressure motor, an auxiliary liquid-pressure pump that is driven by an electric motor and supplies working liquid to the liquid-pressure motor, a pressure detector that detects a liquid pressure of working liquid discharged from the auxiliary liquid-pressure pump, and a switching valve that switches whether or not working liquid from the auxiliary liquid-pressure pump is supplied to the liquid-pressure motor. In a state in which the switching valve is closed and the mixer drum is being driven to rotate by the liquid-pressure motor that is driven by the liquid-pressure pump, the controller opens the switching valve if a liquid pressure detected by the pressure detector reaches or exceeds a preset liquid pressure.

    摘要: A motor vehicle 10 includes a hydromechanical powersplit transmission 11 having a hydraulic pump motor unit drive shaft 44 and a gear 76. The shaft 44 and gear 76 are drivingly connected together with a spline connection 160. The spline connection 160 includes an internal spline connector 161 and an external spline connector 162. Each spline connector 161, 162 includes a spline portion 166, 174 and a generally smooth portion 168, 175 adjacent its spline portion. During assembly, generally smooth portion 168 of the internal spline connector 160 engages and guides spline portion 174 of the external spline connector 162 to longitudinally and circumferentially align the spline portions 174 and 166. After assembly, the spline portions 166, 174 and the generally smooth portions 168 and 175 are radially aligned with and engage one another to form a rigid driving connection.
