摘要： A hydraulic synchronizer selectively couples one or more gears to a drive shaft. The synchronizer has a shaft hub with a splined annulus and a fluid passage. A ring is disposed about the shaft hub and movable along a rotation axis of the shaft hub. A shift collar is fixedly coupled to the ring and has a splined annulus engaged with the splined annulus of the shaft hub. The shift collar is configured to engage splines of a gear when the ring is in an engaged axial position and to disengage the splines of the gear when the ring is in a neutral position. The shift collar transmits rotational input from the shaft hub to the gear when the ring is in the engaged axial position. Hydraulic chambers receive hydraulic fluid from the fluid passage and move the ring to the engaged and neutral positions.

摘要： A steering control system is disclosed for a vehicle train with a tow vehicle, a first towed vehicle with at least one ground-engaging member, and a second towed vehicle. A steering assembly may be configured to control steering of the at least one ground-engaging member. One or more sensing devices may be configured to determine orientation information for one or more of the tow vehicle, the first towed vehicle, and the second towed vehicle, during operation of the vehicle train. A steering correction may be determined for the second towed vehicle based upon the determined orientation information. The steering correction may be applied for the second towed vehicle by controlling the steering assembly to steer the first towed vehicle.

摘要： A forkless synchronizer arrangement selectively couples one or more gears to a drive shaft that is rotatable about a rotation axis. A shift collar, rotated by the drive shaft, is configured to disengage from a first of the gears when in a first neutral axial position and to engage the first gear when in a first engaged axial position to transmit rotational input from the drive shaft to the first gear. A rail is arranged in parallel with the rotation axis. A rail arm has an end fixedly coupled to the rail and another end coupled to the shift collar to permit relative rotation and to transmit axial shifting movement to the rail in response to axial movement of the shift collar between the first engaged and neutral axial positions. A sensor proximate the rail senses an axial position of the rail.

摘要： A method for controlling a power-split gear shift device in a vehicle by providing an electric variator and a transmission with variable gear shift and connecting a drive motor to a traction drive of the vehicle. The electric variator has a compound gear train with at least one first and at least one second electric machine. The method also includes providing a controller for the electric machines for steplessly varying a gear shift of the compound gear train. Upon detection of an external power requirement by an electric consumer, a gear shift region of the transmission with variable gear shift is set to operate the first electric machine in a generator mode and to operate the second electric machine to compensate for an existing power deficit or a power excess relative to an external power demand.

摘要： An infinitely variable transmission includes a clutch, a brake and a first planetary gear set, including first and second components, and a double planetary gear set, including input and output components and additional third and fourth components. The first component receives power from an engine. The double planetary set sums mechanical power from the first planetary set and an infinitely variable power source (“IVP”). The third component receives mechanical power from a IVP. The second component directly transmits power to the input component. The clutch directly controls power transmission between the first and second components. The brake engages the fourth component to stop its rotation. The output component receives mechanical power directly from the input component and the fourth component. During operation of the engine, controlled actuation of the brake and the clutch causes the output component to be powered by the infinitely variable power source but not by the engine.

摘要： A control system is provided for an implement such as a mower having a rotary blade driven by a gear box which is driven by a PTO shaft of a vehicle which is coupled to the mower. The vehicle has a drivetrain which drives the PTO shaft. The control system includes an acceleration sensor for sensing vibrations of the blade and generating a blade vibration signal. A PTO speed sensor generates a PTO shaft speed signal. A control unit is connected to the sensors and to the drivetrain. The control unit generates, as a function of the speed signal, an expected acceleration value representing a blade loss condition and an expected acceleration value range. The control unit compares the vibration signal to the range, and the control unit stops the drivetrain from rotating the blade if the vibration signal is within the range.
