    Abstract: A P2 transmission and engine assembly includes a transverse mounted transmission having: a transmission first end and a transmission second end oppositely positioned with respect to the transmission first end; and a transmission gearbox portion having a first cavity positioned at the second end. A torque converter is positioned at the transmission first end. An electric motor is positioned within the first cavity and is rotatably connected to the torque converter using a turbine shaft. A one-way clutch is connected to the turbine shaft and releasably connects the turbine shaft to the torque converter. The one-way clutch when disengaged disconnects the torque converter from the turbine shaft.

    Abstract: A torque transferring transmission-drive system includes a first friction surface. A second friction surface is directed toward the first friction surface. A reaction plate is positioned between the first friction surface and the second friction surface. A piston is actuated by a fluid pressure to displace the first friction surface toward the second friction surface, frictionally engaging the reaction plate between the first friction surface and the second friction surface. At least one strap spring in a clutch engaged condition elastically compresses to allow the reaction plate to be frictionally engaged between the first friction surface and the second friction surface, and in a clutch disengaged condition the at least one strap spring elastically expands to create a clearance between the reaction plate and each of the first friction surface and the second friction surface.

    Abstract: A passive opening transmission clutch system includes a backing plate having multiple tab slots, each of the tab slots having a tapered wall. A first reaction plate has multiple first tapered spline teeth oriented transverse to a plane of the first reaction plate. The first tapered spline teeth are positioned at least partially in individual ones of the tab slots in a clutch disengaged condition. The first tapered spline teeth when displaced further into the tab slots and toward the backing plate define a clutch engaged condition. A first friction plate is in frictional contact with the first reaction plate in the clutch engaged condition, the first friction plate when rotated generating a rotational force on the first reaction plate. The rotational force acts against the first tapered spline teeth to induce the first reaction plate to slidably move away from the backing plate.

    Abstract: A motor vehicle planetary axis transfer gearbox system includes a connective housing connecting an engine to a transmission of a motor vehicle with the transmission being positioned forward of the engine. An axis of an engine output shaft is oriented substantially parallel to an axis of a transmission input shaft. Both the axis of the engine output shaft and the axis of the transmission input shaft are oriented substantially perpendicular to a central axis of the motor vehicle. A planetary gear set is connected to one of the engine output shaft or the transmission input shaft acting to reverse a direction of rotation of either the engine output shaft or the transmission input shaft to match a direction of rotation of both the engine output shaft and the transmission input shaft. A drive chain connects the engine output shaft to the transmission input shaft.

    Abstract: A damper system includes a turbine shaft rotatably connected to a torque converter having a clutch. A hydraulically actuated clutch is coupled to the turbine shaft. A first spring cage has a first cage portion connected to the hydraulically actuated clutch and a second cage portion connected to a friction plate. A first spring set is connected to the first and second cage portions. Springs of the first spring set are deflected by axial rotation between the first and second cage portions when the torque converter clutch is engaged. A second spring cage has a first cage section connected to the hydraulically actuated clutch and a second cage section connected to a torque converter turbine. A second spring set has second springs having a spring constant different than the first spring set. The second spring set springs are deflected by axial rotation between the first and second cage sections.

    Abstract: An assembly for use in a transmission of a motor vehicle includes a planetary gear set that defines an axis of rotation and includes a planetary carrier member, the planetary carrier member having at least one window. A piston is disposed on a first side of the planetary gear set and a clutch pack is disposed on a second side of the planetary gear set opposite the first side. An interplanetary actuator is in contact with the piston and the clutch pack and is slidably disposed in the window of the planetary carrier member. Actuation of the piston in turn translates the interplanetary actuator to engage the clutch pack.
