Abstract: A power transmission device includes a rotatable input shaft, a rotatable output shaft and a ring gear fixed for rotation with the input shaft. A carrier is fixed for rotation with the output shaft. A pump assembly includes an inner rotor supported for rotation on the carrier and an outer rotor encompassing the inner rotor. The outer rotor is in driving meshed engagement with the ring gear. The pump provides pressurized fluid to one of first and second fluid ports. A flow restrictor is moveable to selectively restrict fluid flow relative to one of the first and second ports.

Abstract: In one form, the present teachings provide a power transmission device that includes a rotatable input shaft, a rotatable output shaft and a ring gear fixed for rotation with the input shaft. A carrier is fixed for rotation with the output shaft. A pump assembly includes an inner rotor supported for rotation on the carrier and an outer rotor encompassing the inner rotor. The outer rotor is in driving meshed engagement with the ring gear. The pump provides pressurized fluid to one of first and second fluid ports. A flow restrictor is moveable to selectively restrict fluid flow relative to one of the first and second ports. In another form, the present teachings provide a power transmission device with a ring gear and a carrier assembly that are coupled to first and second rotary members, respectively. The carrier assembly includes pump assemblies, each of which having a rotor pin, an inner rotor rotatably received on the rotor pin, and an outer rotor that is rotatably received over the inner rotor.

Abstract: The invention concerns a vehicle transmission for commercial vehicles having an additional continuous braking device wherein the additional continuous braking device, in addition to braking, is provided as a startup retarder (2) to start the vehicle.
