Abstract: A one-way clutch includes a clutch body and body bore. A clutch plate stack includes first, second, and third clutch plates, the first and third clutch plates fixed to the clutch body. The second clutch plate rotates axially on a longitudinal axis. The first clutch plate includes a first strut cavity and the second clutch plate includes a second strut cavity. A forward strut is rotatably connected to the second clutch plate and biased toward the first clutch plate. The forward strut when positioned in the first strut cavity defines a clutch engaged position preventing second clutch plate rotation in a first rotational direction, while allowing rotation in a second rotational direction. A reverse strut slidably disposed in a strut bore extends through the third clutch plate, is partially positioned in the second strut cavity and is displaced in the strut bore during rotation of the second clutch plate.

Abstract: The present invention provides a gear absolute position sensor assembly (GAPS) that senses the current absolute, position of the shift lever of a manual transmission. The sensor assembly provides data to an associated electronic controller such as an engine control module (ECM) regarding the current position of the shift lever, such as an engaged gear. The sensor assembly preferably comprises at least one Hall effect or other type of magnetic field (proximity) sensors in combination with an application specific integrated circuit (ASIC) which is supplied with data from the sensors, decodes the output of the sensors and provides an output identifying a specific engaged gear or neutral for use by vehicle or engine management electronics. The sensors are mounted proximate the shift linkage at a location where they can sense both rotation and translation.

Abstract: A transmission includes an input drive shaft, a drive gear, an idler gear, and a driven gear. The drive gear is rotationally fixed to the input drive shaft which, in turn, may but not necessarily, be powered by an engine. The idler gear may include a second set of gear teeth mounted to a bearing wherein the second set of gear teeth are formed from polymeric material. The second set of gear teeth for the idler gear may be in meshing engagement with the first set of gear teeth. The driven gear may include a third set of gear teeth in meshing engagement with the second set of gear teeth. The driven gear may be rotationally fixed to a pump shaft for a transmission pump. The input drive shaft, the drive gear, the idler gear, and the driven gear are configured to power a transmission pump.

Abstract: The present invention provides improved, real time sensing of pressure supplied to the hydraulic operator of a clutch for a motor vehicle driveline power take off. A proportional sensor in the hydraulic line to the power take off clutch actuator provides a data signal in real time of the actual pressure applied to the clutch actuator. This signal is provided to the power take off control module (PCM) and/or to the transmission control module (TCM). The power take off control module, having instantaneous data regarding the pressure applied to the hydraulic operator achieves two important operating functions: monitoring and feedback.
