    摘要: A mixer drum driving device includes a mixer drum, a hydraulic motor, a hydraulic pump, an auxiliary hydraulic pump for rotating the mixer drum for mixing by supplying pressure oil to the hydraulic motor independently of the hydraulic pump, and a direct-current brush motor for driving and rotating the auxiliary hydraulic pump. In the case of rotating the mixer drum for mixing, the mixer drum is driven and rotated by driving only the auxiliary hydraulic pump by the direct-current brush motor.

    摘要: A pump system includes a closed-loop fluid circuit and an open-loop fluid circuit. The closed-loop fluid circuit includes a motor for rotating a first component connected to the closed-loop fluid circuit. A closed-loop pump drives the motor up to a first maximum rotational speed. The open-loop fluid circuit includes an open-loop pump for driving a second component connected to the open-loop fluid circuit. A control circuit includes a control valve for switching the outflow from the open-loop pump. The control valve selectively connects the open-loop pump to the closed-loop fluid circuit and simultaneously disconnects the open-loop pump from the open-loop fluid circuit. When the open-loop pump is connected to the closed-loop circuit, the closed-loop pump and the open-loop pump drive the motor at a second rotational speed greater than the first maximum rotational speed.

    摘要: A vehicle and drive system control method for a vehicle including first and second traction elements coupled to the vehicle, a variable displacement pump, a bi-directional variable displacement first motor coupled to the first traction element, and a bi-directional second motor coupled to the second traction element. The pump, and first and second motors are coupled fluidly in series with one another. A control unit can determine a desired speed for the traction elements, and determine pump, first and/or second motor displacements based on the desired speed. First and second speed sensors can sense output speeds of the motors, and the pump, first and/or second motor displacements can be determined based on the motor output speeds. Articulation and steering sensor signals can also be used to determine pump, first and/or second motor displacements.
