  • Patent number: 11192436
    Abstract: A drive unit includes a first electric machine including a first machine shaft, a second electric machine including a second machine shaft, and a differential interconnecting the first electric machine and the second electric machine. The differential includes a park gear. The drive unit further includes a single park system configured to engage the park gear of the differential to simultaneously stop rotation of both the first electric machine and the second electric machine. The park system includes a single pawl movable between an engaged position and a disengaged position. The pawl is spaced apart from the park gear of the differential in the disengaged position to allow the park gear to rotate. The single pawl is in contact with the park gear of the differential in the engaged position to preclude rotation of the park gear.

  • Publication number: 20210083546
    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.

  • Patent number: 10780849
    Abstract: Presented are electric drive unit (EDU) assemblies with integrated power electronics, methods for making/operating such EDU assemblies, and motor vehicles equipped with such EDU assemblies. An EDU assembly includes an outer housing that mounts to a vehicle body. The EDU outer housing has internal motor and transmission chambers and an external cavity. A traction motor is mounted inside the motor chamber and drives one or more vehicle wheels to thereby propel the vehicle. A gear train is mounted inside the transmission chamber and drivingly connects the traction motor to the vehicle wheels. An integrated power electronics (IPE) unit, which is operable to control the traction motor, includes an IPE outer housing with a housing chassis mounted inside the external cavity, and a main housing mounted on the housing chassis to define therebetween a power electronics (PE) chamber. Multiple integrated circuit (IC) PE modules are mounted inside the PE chamber.
