Abstract

The invention relates to a transmission device for motor vehicles, wherein the transmission device has several wheel sets for forming gears and wherein the transmission device has an internal gear shift and a gear actuator for actuating the internal gear shift for engaging and disengaging gears, and wherein the transmission device has a transmission housing in which the wheel sets provided for forming gears are held, wherein the gear actuator has two separate function modules, of which a first one is a drive module and of which a second is an actuating module, wherein the drive module has at least one, especially electronically-controlled, drive device like an electric motor and wherein during engaging and disengaging gears, the actuating module is in the power flow between the drive module and the internal gear shift and wherein the actuating module and the drive module are mounted separately on the transmission housing.
