    摘要： The invention relates to a dual motor hydraulic hybrid transmission. The transmission comprises a power source, a hydraulic circuit including a pump drivingly engaged with the power source and two displacement units, a hydraulic accumulator assembly including high and low pressure accumulators, one or more control valves, and an output shaft drivingly engaged with the first hydraulic displacement unit. The displacement units are in fluid communication with the hydraulic pump. The accumulators are in fluid communication with the hydraulic circuit. The second hydraulic displacement unit is drivingly engaged with the output shaft. The control valves are configured to selectively fluidly connect the hydraulic pump to the first hydraulic displacement unit while fluidly disconnecting the hydraulic pump from the second hydraulic displacement unit; and, simultaneously, fluidly connect the hydraulic accumulator assembly to the second hydraulic displacement unit while fluidly disconnecting the hydraulic accumulator assembly from first hydraulic displacement unit.

    摘要： A hydrostatic assembly employing a 1st hydraulic piston drive unit is described in which the output is increased without using additional servo assemblies by incorporating a 2nd hydraulic piston drive unit, coupling the drive shafts of both drive units together, and employing a common means to simultaneously adjust displacement of both the 1st and 2nd hydraulic piston drive units. In such embodiments, coupling the drive shafts together such that the 1st hydraulic piston drive unit is rotationally offset with respect to the 2nd hydraulic piston drive allows for a reduction in the amplitude of pressure pulsations associated with the hydrostatic assembly output, thereby smoothing out operation and improving durability.

    摘要： A hydraulic machine includes first and second opposing motors. Displacement of the first and second motors is controlled such that while the sum of the displacements of the first and second motors is below a threshold, the displacement of the first motor is substantially equal to the sum, and the displacement of the second motor is substantially equal to zero. While the sum of the displacements is above the threshold, the displacement of the first motor may be substantially equal to the displacement of the second motor, either as a displacement percentage or as a displacement volume. The first motor may be equal in capacity, or smaller than the second motor.

    摘要： A drivetrain system for use in a mobile machine is disclosed. The drivetrain system may have a first rotary fluid actuator, a second rotary fluid actuator, an input device, and a controller in communication with the first rotary fluid actuator, the second rotary fluid actuator, and the input device. The controller may be configured to determine a desired change in an effective gear ratio of the drivetrain system, and determine a total displacement change associated with the first and second rotary fluid actuators that produces the desired change in the effective gear ratio. The controller may also be configured to compare the total displacement change to a threshold change level, affect simultaneous displacement changes in the first and second rotary fluid actuators when the total displacement change exceeds the threshold change level, and affect sequential displacement changes in the first and second rotary fluid actuators when the total displacement change is less than the threshold change level.

    摘要： A hydraulic circuit including a first motor set, and a second motor set for driving vehicle-moving means situated one behind the other. The circuit has first, second, third, and fourth main ducts for feeding the motor sets in parallel. The device includes a selector suitable for taking up a first stable position making the feeding in parallel possible by interconnecting in pairs the feed and discharge main ducts, and for taking up a second stable position in which one of the motor sets is inactive because one of the main ducts is connected to one of main ducts of the other set. Between the stable positions, the selector can take up a temporary position, in which all four main ducts are interconnected. At least while the selector is moving in one direction between its two stable positions, the temporary position is sustained in an intermediate stage during which at least one of the interconnections between the main ducts of the first and second motor sets is constricted.

    摘要： A hydraulic system includes first and second pumps, first and second motors, and three valves for selectively creating combined and basic hydraulic flow. The arrangement of valves permits combined flow to be provided to both motors in series to cause high speed operation of the motors, and permits combined flow to be provided to one motor and basic flow to the other motor. When applied to a vehicle, the arrangement provides a steerable high speed series arrangement of the vehicle's drive motors.
