Transmission device for an electrically drivable vehicle axle, drive device for an electrically drivable vehicle axle, and vehicle

A transmission device (5) for an electrically drivable vehicle axle (1) comprising:

• a transmission housing (11);
• a transmission input shaft (7);
• a transmission output shaft (10) connected to the transmission input shaft (7) via gear-wheel pairs (8, 9);
• and
• a parking lock device (15), the transmission output shaft (10) being rotationally fixable via the parking lock device (15), the parking lock device (15) being arranged in the transmission housing (11), the parking lock device (15) comprising an electric actuator (16) for actuating a locking pawl (18) engageable with or disengageable from a parking interlock gear (19) operatively connected to the transmission output shaft (10),
• wherein the locking pawl (18) and the parking interlock gear (19) are arranged in an interior space (14) of the transmission housing (11) that is acted upon by oil, and the electric actuator (16) is arranged in an oil-free interior space (13) of the transmission housing (11),
• wherein an output shaft (21) of the electric actuator (16) extends through an intermediate wall (12) separating the interior space (14) that is acted upon by oil from the oil-free interior space (13), and the electric actuator (16) is operatively connected to the locking pawl (18) on a side of the intermediate wall (12) facing away from the oil-free interior space (13), and
• wherein an actuator housing (20) of the electric actuator (16) is within the oil-free interior space (13) of the transmission housing (11).
