Patent ID: 7779713

Claim:
A transmission device for motor vehicles, comprising: a plurality of wheel sets ( 18 , 20 , 22 , 24 ) for forming gears, wherein said transmission device ( 1 ) has an internal gear shift ( 26 ) for engaging and disengaging gears and a gear actuator ( 42 ) for actuating said internal gear shift ( 26 ), wherein said transmission device ( 1 ) has a transmission housing ( 88 ) in which said plurality of wheel sets ( 18 , 20 , 22 , 24 ) provided for forming gears are held, characterized in that said gear actuator ( 42 ) has a first and a second function module, said first function module is a drive module ( 58 ) and said second function module is an actuating module ( 56 ), wherein said drive module ( 58 ) has at least one electronically-controlled drive device, and wherein a first kinematic interface for shifting and a second kinematic interface, separate from the first kinematic interface, for selecting are provided in the transmission device between the actuating module ( 56 ) and said drive module ( 58 ) such that during engaging and disengaging gears, said actuating module ( 56 ) is in a power flow between said drive module ( 58 ) and said internal gear shift ( 26 ) and said actuating module ( 56 ) and said drive module ( 58 ) are mounted separately on said transmission housing ( 88 ).
