Abstract
A transmission assembly for an electric drive comprises a drive shaft, a reduction gearing rotatably drivable by the drive shaft, a power distribution unit drivingly connected to the reduction gearing and configured to transmit a rotational motion to two output parts, a parking lock unit having a parking ratchet wheel which is connected in a rotationally fixed manner to a torque-transmitting member in the power path between the drive shaft and the output parts, and having a controllable locking element which can be selectively engaged with the parking ratchet wheel; wherein the parking lock unit is arranged in a parking lock housing which is liquid-tightly sealed with respect to a transmission housing so that a first oil bath in the transmission housing is separated from a second oil bath in the parking lock housing.
