摘要： A drivetrain for an agricultural vehicle and method for controlling the same. The drivetrain includes first and second driven axles with a variable pivot angle hydraulic motor connectable to drive the first axle through engagement of a first clutch mechanism. A further motor is connected to drive the second axle. In operation, the pivot angle of the variable pivot angle hydraulic motor is reduced with variation in a vehicle parameter value, such as transmission ratio or ground speed, to a point at which the pivot angle reaches zero at a first parameter value. With the pivot angle at zero and parameter value continuing to vary due to the drive of the further motor, the first clutch mechanism is disengaged at a second parameter value, with the first and second parameter values separated by an interval determined at least partly by an operating characteristic of the first clutch mechanism.

摘要： A method of drivingly engaging a first motor of a dual motor drive unit with an output shaft driven by a second motor of the dual motor drive unit includes actuating a clutching device for drivingly engaging the first motor with the output shaft. Next, a rotational speed of the first motor is synchronized with a rotational speed of the output shaft. When the rotational speed of the first motor and the rotational speed of the output shaft are synchronized, an output torque of the first motor is reduced. When the clutching device drivingly engages the first motor with the output shaft, the output torque of the first motor is increased. The invention further relates to a dual motor drive unit for carrying out the method.

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： In a process for hydrostatically driving a vehicle comprising at least two ideal axles (12) of which each has at least one drivable wheel (11), each drivable wheel (11) being driven by at least one hydraulic motor (9) connected to at least one hydraulic source (6), and the driving power being transmitted from a hydraulic motor (9) via a transmission system (10, 35) to the respective wheel (11), the vehicle is to be usable under different performance requirements and is to be produced and operated in a simple and inexpensive manner. This is achieved in that the drivable wheels (11) are initially driven with a first identical ratio of the transmission system (10, 35), while, when a first load limit is reached, the effective drive of the wheels (11) of at least one ideal axle (12) is reduced and, when a second load limit is reached, the ratio of the transmission system (10, 35) is changed, and at least the wheels (11) driven before the first load limit are equally driven. Furthermore, a hydrostatic drive, in particular for performing the process, with at least two ideal axles which have each a drivable wheel (11), each drivable wheel (11) being connected to at least one hydraulic motor (9) connected to at least one hydraulic source (6) and a transmission system (10, 35) being arranged between each hydraulic motor (9) and the associated wheel (11), is suggested for the solution of the above-mentioned technical problem in such a manner that the ratio of the transmission system (10, 35) is variable.

摘要： A two-speed, pilot-operated selector valve which directs hydraulic fluid to two motor elements with a common output shaft to obtain a high-torque, low-speed mode, or to one motor element, while recirculating the second element in a loop, to obtain a low-torque, high-speed mode. The spool has a built-in logic mechanism which, while shifting from one position to the other, prevents any momentary condition where a motor discharge port is blocked or a fluid path exists that bypasses both motor elements.

摘要： The steerable wheels of a hydraulically driven vehicle are provided with auxiliary motors which are connected in parallel both with each other and with the motor which powers the main drive wheels. A selector valve permits the motors for the steerable wheels to be optionally connected and disconnected from the reversible, variable displacement main pump. Flow dividers in the hydraulic lines limit the maximum flow of fluid to any one hydraulic motor. The auxiliary motors are of the variable displacement type, enabling them to be destroked to neutral when disconnected from the main pump. Destroking to neutral eliminates energy loss due to the pumping of large quantities of hydraulic fluid through a closed loop when the motors are driven by the wheels.
