  • Patent number: 12160160
    Abstract: A drive assembly with passive cooling and/or lubrication. The drive assembly includes a housing, an electric motor having a shaft that is rotatably drivable about an axis of rotation, and a gear assembly located in the housing. The gear assembly is rotatably drivable by the shaft, and includes a plurality of gears that are rotatable in a rotational drive direction. An oil removal opening is located on an inner wall of the housing aligned with the gears, with the oil removal opening being located between ?45 and +45 degrees from a horizontal plane that extends through the axis of rotation on a rotationally upward moving side of the gears in the rotational drive direction. The oil removal opening has an upper edge that is angled and faces counter to the rotational drive direction. An oil delivery channel extends from the oil removal opening to a feed port for the motor.
