1. A drive block of an electric motor-driven motor vehicle drive,
comprising a first electric machine and a first transmission and a second electric machine and a second transmission,
wherein the first transmission is arranged on an end face of the first electric machine, and the second transmission is arranged on an end face of the second electric machine,
wherein respective arrangements are at least partially congruent with each other in a longitudinal vehicle direction,
wherein centers of rotation of the electric machines define a structural plane through rotary shafts thereof,
in relation to which structural plane a transmission output is offset,
so that a V-shaped arrangement having an angle smaller than 180 degrees between arms of the V-shaped arrangement is formed from a first position of the first rotary shaft, from a second position of the second rotary shaft and from the transmission output of one of the transmissions, on a plane parallel to the transmission,
wherein at least one of an inverter block and a parking lock device is provided, and
wherein at least part of at least one of the inverter block and the parking lock device is located to a side of at least one of the electric machines and between the transmissions.
