    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 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 transmission for a vehicle is disclosed. The transmission includes a casing defining a first cavity and a second cavity inside the casing, with the first cavity selectively open to outside of the casing. The transmission also includes a platform at least partially disposed inside the casing to separate the first and second cavities. Furthermore, the transmission includes a power inverter module selectively disposed in the first cavity. The power inverter module includes a cooling system for cooling the power inverter module. The transmission also includes a guide attached to the platform and the casing within the second cavity such that the guide provides fluid communication between the cooling system of the power inverter module within the first cavity and outside of the casing while bypassing the second cavity.

    Abstract: A method of joining parts, where at least one of the parts has a faying surface defining grooves therein. One of the parts is formed of a majority of titanium, and the other part is formed of a majority of iron. The method includes providing a set of opposed welding electrodes disposed on a side of each part and applying pressure to and heating the parts via the set of electrodes to form a joint between the parts. A bonded assembly includes a first part formed of a majority of titanium and a second part formed of a steel alloy. The first and second parts having a bond that includes a portion of the first part directly in contact with and attached to a portion of the second part. The parts may be a titanium-containing differential carrier case bonded to a steel gear.
