Abstract
A transmission (3) for an electrically driveable axle (1) of a motor vehicle has a drive input shaft (4) that can be driven by at least one electric machine (2, 12), for driving the axle (1) of the motor vehicle. The drive input shaft (4) is a hollow shaft with radially internal toothing (13) and can receive an electric machine coupling shaft (21) that can be inserted into the hollow shaft (4). The hollow shaft (4) has radially external toothing (22) that interacts with the radially internal toothing (13). A transmission of said type can be used universally, specifically for electric machines with different rotor shafts and/or for one or two electric machines.
