摘要： A plastic coolant fitting for a hybrid module includes an upper coolant tube with a first straight section and a rounded section, and a lower coolant tube with a second straight section fixed to the rounded section by spin welding. The rounded section may include a ring-shaped groove and the second straight section may include a ring-shaped protrusion installed in the ring-shaped groove. Prior to spin welding, the ring-shaped groove and the ring-shaped protrusion may include respective complementary trapezoidal cross-sections.

摘要： A shipping strap for a hybrid module includes a first annular surface, a second annular surface, and a central bore. The first annular surface includes a first orifice for receiving a first fastener for fixing the shipping strap to a hybrid module housing, or receiving a dowel pin for radially positioning the shipping strap relative to the hybrid module housing. The second annular surface includes a second orifice for receiving a second fastener for securing the shipping strap to a rotor for an electric machine to axially position the rotor in the hybrid module housing. In some example embodiments, the shipping strap has a through bore aligned with the central bore, and a lifting element installed in the through bore for installing the hybrid module in a multi-speed transmission. In an example embodiment, the lifting element is installed in the through bore by a threaded connection.

摘要： A one-way clutch including: a wedge plate including a first radially innermost circumference with a first plurality of ramps; an inner race including a first radially outermost circumference with a second plurality of ramps and arranged to receive torque and transmit the torque to the wedge plate in a lock-mode for the one-way clutch; and a weighting element engaged with the wedge plate. The weighting element is arranged to displace, in response to rotation of the inner race, to radially contract the wedge plate.

摘要： A generator module for a vehicle includes a housing with a first conical surface, a rotor assembly with a second conical surface, aligned with the first conical surface, and a spring arranged to push the second conical surface into contact with the first conical surface. In an example embodiment, the first conical surface or the second conical surface includes a plastic surface or a friction paper surface. In an example embodiment, the rotor assembly is axially displaceable within the housing to compress the spring and move the second conical surface away from the first conical surface.

摘要： A hybrid drive assembly is provided having a hybrid drive housing with an electric motor and a disconnect clutch therein. A transmission is connected to the hybrid drive housing and a torque converter is provided between the electric motor and the transmission. A baffle extends radially between the torque converter and the hybrid drive housing. The baffle includes a ring-shaped body that is affixed to the hybrid drive housing and extends completely around a transmission side periphery of the hybrid drive housing. A fluid pathway is located on or in the baffle, and orifices extend from the fluid pathway toward the electric motor. A fluid inlet port is connected to the fluid pathway, and a fluid connection is provided from a pressurized fluid source to the fluid inlet port. This allows fluid circulated by a pump within the transmission, to be sprayed on the electric motor for cooling.

摘要： A rotor for an electric motor includes an axis, a rotor carrier a plurality of rotor segments, a first end plate, a second end plate, and a spring element. The rotor carrier has a tubular portion with a cylindrical surface and a radial wall extending radially outwardly from the cylindrical surface. The plurality of rotor segments circumscribe the cylindrical surface. The first end plate is disposed at a first axial end of the plurality of rotor segments adjacent to the radial wall. The second end plate is disposed at a second axial end of the plurality of rotor segments. The spring element presses the first end plate, the plurality of rotor segments, and the second end plate against the radial wall. The spring element includes a ring portion and a plurality of segments extending axially from the ring portion.

摘要： A resolver assembly for an electric motor includes a housing, a resolver stator for an electric motor, and a clamping plate. The clamping plate includes a first radially extending portion fixed to the housing, a second radially extending portion pressing the resolver stator towards the housing, and an axially extending portion arranged axially between the first radially extending portion and the second radially extending portion. In an example embodiment, the clamping plate is elastically deformed. In an example embodiment, the resolver assembly includes a bolt extending through an orifice in the first radially extending portion radially outside of the axially extending portion to fix the clamping plate to the housing.
