20090247342 - Saddle type vehicle with forward/reverse changeover mechanism: The forward/reverse travel changeover mechanism includes a projection formed by causing an output power shaft for outputting the power from a main transmission to project to the outside of a case, a carrier rotatably supported around the projection relative to a sun gear provided rotatably integrally with the projection, a... Agent: Birch Stewart Kolasch & Birch

20090247343 - Automatic transmission gear and clutch arrangement: A transmission is provided having an input member, an output member, four planetary gear sets, a plurality of coupling members and a plurality of torque-transmitting devices. Further, a hydraulic fluid control circuit is provided for controlling the operation of the plurality of torque-transmitting devices. The hydraulic fluid control circuit receives... Agent: Vivacqua Law, Pllc

20090247344 - Shift control apparatus for automatic transmission: Strain gauges and a torque value calculating unit detect a value for torque acting on a sun gear, based on a reaction force. A torque phase detecting unit detects start of a torque phase at which only torque distribution changes while a gear ratio stays at the same level as... Agent: Bacon & Thomas, Pllc

20090247345 - Drive for a working machine, in particular a press drive, and a working machine, in particular a forming press: A drive for a working machine, in particular a press drive, includes an electric motor, a transmission, and a brake. The brake is disposed between the transmission and the electric motor. A forming device, such as a forming press, includes a press housing, a press shaft, and a drive for... Agent: Lerner Greenberg Stemer LLP

20090247346 - Two speed planetary electric shift gearbox: A direct drive electric shift two speed planetary gearbox using a linear actuator to engage selectively planet, sun and ring gears to provide a low speed mode, a neutral mode, and a high speed mode of operation with significant fuel efficiencies.... Agent: Marcus G Theodore, Pc

20090247347 - Lubricating device for pinion gear in planetary gear set: A lubricating device for a pinion gear in a planetary gear set provides smooth lubrication between a pinion shaft and a pinion bearing, and prevents scuffing due to lack of lubrication between the pinion shaft and a pinion gear. Oil may be supplied into a hollow of the pinion shaft... Agent: Morgan, Lewis & Bockius LLP (sf)

20090247348 - Planetary transmission: A planetary gear set lubricating unit which supplies oil from inside a component adjacent the planetary gear set, via a radial bore and an oil catcher, axially through a bore of a planetary gear bolt to planetary gear bearings. The oil catcher forms a ring-shaped chamber, which can be filled... Agent: Davis & Bujold, P.l.l.c.

20090247349 - Reduction gear transmission: A crank member (22) is arranged between a through hole 58 of an external gear (20a), a through hole (59 of an external gear (20b), and a support pin (24). An eccentric disk (25) that fits with the through hole (58) of the external gear (20a) and an eccentric disk... Agent: Oliff & Berridge, Plc

20090247350 - Electronic locking differential with direct locking state detection system: An axle assembly with an electronic locking differential that employs a locking mechanism having components that are fixed to one another along an axis such that they co-translate with one another when the actuator that effects the locking and unlocking of the differential is operated.... Agent: Harness, Dickey & Pierce, P.L.C
