Abstract
An electric drive assembly comprises a parking lock housing, a sleeve-shaped shaft journal supported in the parking lock housing so as to be rotatable around a rotational axis, wherein the shaft journal comprises a connecting profile for connection to the driveshaft of the electric drive assembly in a rotationally fixed way; a ratchet wheel connected to the shaft journal in a rotationally fixed way and received in a receiving space between the base portion and the cover portion; a locking element movably supported in the parking lock housing and that can be transferred into a locking position for blocking the ratchet wheel and into a releasing position for releasing the ratchet wheel; and a controllable actuator for actuating the locking element; wherein an inner diameter of the parking lock housing in the region of the ratchet wheel substantially corresponds to a greatest outer diameter of the ratchet wheel.
