摘要： An example includes a hydraulically controllable coupling to couple a rotating input and to an output to rotate, or to decouple the input and the output, with coupling and decoupling modes selected by switching a hydraulic device such as a vane pump between a pumping mode and a mode in which it does not pump. In an example, the system cooperates with a transmission to increase the number of possible gear ratios in some examples.

摘要： A hydraulic transmission circuit comprising three or four coupled hydraulic elementary motors, each elementary motor having a first and a second secondary enclosure. The circuit includes four distribution valves for which the respective outlet channels may be selectively connected to two main conduits for supplying fluid to and discharging fluid from the circuit. The outlet channels of the first and second valves are connected to at least one of the first secondary enclosures; those of the third and fourth valves are connected to at least one of the second secondary enclosures. Each of the elementary motors has a first secondary enclosure connected to a single valve from among the first or second valve and a second secondary enclosure connected to a single valve from among the third or fourth valve. The valve pairs thereby connected to said elementary motors respectively, are all distinct, two by two.

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 turf care machine includes a base mounted on a plurality of wheels, a support structure affixed to and extending from the base for supporting a turf machine operator interface, and a hydraulic control system for regulating the speed and direction of the mower. The hydraulic system includes: an engine with a drive shaft; a single hydraulic pump driven by the engine; a first valve set having an inlet connected to the pump outlet; a first hydraulic wheel motor connected to the first valve set; a second valve set connected to the first valve set and to second hydraulic wheel motor. This drive system has the advantage of using only one pump for driving both drive wheels in a seemingly independent dual path mode of operation, thereby minimizing cost and the number of fluid linkages and parts in such a system.

Therefore, by designing different properties of the pump pressure to be applied to the single traveling and the double traveling, the manipulation ability of the traveling control device is greatly improved.
