An electro-magnetically actuated pawl clutch is adapted to establish a fixed overdrive ratio in a powersplit type hybrid gearing arrangement. The electro-magnetically actuated clutch includes a first race splined to the transmission input shaft and a second race integrally formed into a first gear that is supported for rotation about the input shaft. Electrical current in a non-rotating coil establishes a magnetic field in the first race. The magnetic field causes a set of pawls to pivot with respect to the first race and to engage a cam surface in the second race. The pawls and cams are designed such that, when engaged, the second race can rotate faster than the inner race but cannot rotate slower. The first gear meshes with a second gear fixed to the transmission output shaft.

A transaxle and a parking actuator assembly are provided. The parking actuator assembly may include an actuator, a rack, and the biasing member. The actuator may include a pin biased towards an extended position. The rack may be configured to carry a parking rod and may define first and second ramped recesses each configured to receive the pin. The biasing member may be coupled with the rack and may be configured to bias the parking rod towards engagement with a parking mechanism.

A clutch includes a first race, a second race, a pawl, a post, and a shoe. The second race defines a cam surface. The pawl is supported in the first race to pivot between an engaged position and a disengaged position such that contact between the cam surface and the pawl in the engaged position prevents relative rotation between the first and second races in at least one direction. The post is supported in the first race to slide between a first and a second position such that in the first position the post forces the pawl into the disengaged position. The shoe is configured to pivot with respect to the first race in response to a magnetic field to slide the post into the second position.

Electro-magnetic and centrifugal clutch

A transmission in a vehicle includes a gearbox and a differential. Torque is transferred from an output of the gearbox to an input of the differential via a drive member. This transfers torque to enable the differential to distribute the torque amongst wheels of the vehicle. A transmission housing and a torque converter housing are mounted to one another to at least partially house the gearbox and the differential, respectively. A transmission fluid sump is provided between the housings where transmission fluid gathers. A fluid pump pressurizes the fluid and distributes it amongst working parts in the transmission. A baffle assembly partially contains the drive member and segregates the fluid sump from the drive member. One of the baffles in the assembly includes a lip engaging a portion of an outer flange of the pump to provide a seal between the fluid pump and components within the transmission.

Baffle for automotive transmission

A drive system includes first and second power sources, a planetary gearset including an output, and first and second inputs driveably connected, respectively, to the first and second power sources, a pinion supported for rotation, and a synchronizer for alternately releasing a drive connection between the pinion and output and substantially synchronizing a speed of the pinion and a speed of the output before driveably connecting the pinion and the output.
