Abstract: A propulsion system for a motor vehicle includes a casing having first and second housing portions cooperating with one another to define a cavity. The propulsion system further includes an electric motor disposed within the cavity. A support mechanism is attached to at least one of the first and second housing portions. The support mechanism includes a first side that faces the first housing portion and a second side that faces the second housing portion and is disposed within the cavity. Bearing seats are formed in the first housing portion, the second housing portion, and the second side of the support mechanism. Bearings are engaged with an associated one of the bearing seats and are configured to rotatably support the input member, the layshaft, and the output member in a fixed-free bearing arrangement. The first side of the support mechanism is free of the bearing seats and the bearings.

Abstract: A retention ring is configured to retain components within a transmission assembly. The retention ring has an annular main body defining an opening through a center thereof. The annular main body defines an outer curved surface and an inner curved surface, the annular main body having a distal face disposed in a distal plane and a proximal face disposed in a proximal plane. A first set of retention features extend from the inner curved surface, and a second set of retention features from the outer curved surface. One of the sets of retention features is configured to engage a backing plate or an outer member, and at least one of the sets of retention features is entirely disposed between the proximal plane and the distal plane. A transmission assembly includes the retention ring and an adjacent external snap ring.

Abstract: A bearing and shaft arrangement of an automobile vehicle electric drive unit includes a gearbox. A first electric motor within the gearbox is engaged with and axially rotates a first shaft within the gearbox. A second electric motor within the gearbox is engaged with and axially rotates a second shaft within the gearbox. A first roller bearing assembly supports the first shaft to a first structural member of the gearbox. A second roller bearing assembly supports the second shaft to the first structural member of the gearbox. A thrust bearing is positioned between the first roller bearing assembly and the second roller bearing assembly and directly contacts the first shaft and the second shaft in a drive mode and reacts a first axial load of the first shaft and a second axial load of the second shaft directed toward the first axial load.

Abstract: A continuously variable automatic transmission having a direction selection mechanism with both friction and binary torque transmitting devices. The transmission includes a torque converter which drives a ring gear of a planetary gear assembly. The sun gear of the planetary assembly drives the input of a variable ratio device. In one embodiment, the friction brake is disposed between a planetary gear carrier and a stationary housing or ground and is engaged to provide reverse direction of travel. The binary clutch is disposed between the ring gear and the planet carrier and, when engaged, locks the planetary gear assembly and provides forward direction of travel. In other embodiments, a binary brake is disposed between the planetary gear carrier and the housing and is engaged to provide reverse travel and a friction clutch is disposed between the ring gear and the planet carrier and, when engaged, locks the planetary assembly and provides forward travel.
