Abstract: A supplemental hydraulic motor is provided that is coupled to an output of a continuously variable transmission in order to increase transmission output torque. The supplemental hydraulic motor is powered by a hydraulic steering pump and is also operational as a ground-driven, secondary hydraulic steering pump. In addition, the supplemental hydraulic motor may be used to retard the transmission.

Abstract: A planetary gear train is disclosed. The planetary gear train may include a first planetary gear set, a second planetary gear set, a third planetary gear set, a fourth planetary gear set and a fifth planetary gear set between an input end and an output end. The planetary gear train may further include a brake set having a first brake, a second brake and a third brake, and a clutch set having a first clutch and a second clutch. The first brake, the second brake and the third brake, the first clutch and the second clutch may be selectively actuable to produce three different forward speed ranges and two different reverse speed ranges between the input end and the output end.

Abstract: A transmission system including a clutch pack, a piston to engage and disengage the clutch pack, a lube oil passage to transmit lube oil, a clutch fluid passage to transmit clutch fluid, and a slider valve infinitely movable between an open position and a closed position and in fluid communication with the lube oil passage and the clutch fluid passage. In the open position, the slider valve allows lube oil to flow from the lube oil passage to the clutch pack, and in the closed position, the slider valve prevents lube oil from flowing from the lube oil passage to the clutch pack. When the piston engages the clutch pack, the piston pushes the slider valve to be in the open position, and when the piston disengages the clutch pack, the slider valve remains in the open position based on pressure by the clutch fluid on the slider valve.

Abstract: A continuously variable transmission includes two planetary gear sets having two outputs. A variator drives a ring gear of the second planetary gear set, and a transmission input shaft is driven by the engine, which also drives the variator and the planetary input. Second and third output shafts are connected to a transmission output shaft. A first clutch is connected to the first output shaft, a second clutch is connected to the second planetary output and engages a first drive gear. A third clutch is connected to the first output shaft and releasably engages the first drive gear, a fourth clutch is connected to the first drive gear and releasably engages the second output shaft, and a fifth clutch is connected to the first drive gear and releasably engages the third output shaft.

Abstract: A piston actuated synchronizer system for a split torque transmission where the piston is attached directly to the synchronizer shift collar on the synchronizer centerline to provide the required actuation in a small volume of space and resolve fork and rod deflection issues seen on other synchronizers that use such a system. The piston is pressure applied and spring released. This design also uses a displacement sensor to monitor synchronizer engagement.

Abstract: A countershaft transmission includes an input member drivingly connected to a power source and at least one directional clutch assembly structured and arranged to be selectively engageable with the input member. At least one speed clutch assembly is structured and arranged to be selectively engageable with the at least one directional clutch assembly. A dual range assembly is structured and arranged to be selectively engageable with the at least one speed clutch assembly. An output member is selectively engageable with the dual range assembly wherein a rotational speed of the input member is transformed to one of a high range speed or a low range speed of the output member through the dual range assembly.
