Abstract:
1. A motor vehicle drive train arrangement with a main drive axle ( 13 ) and an auxiliary drive axle ( 15 ) having a transmission output shaft ( 10 ) with a main drive train ( 11 ) driven by the transmission output shaft ( 10 ), via an axle drive ( 12 ) for driving the main drive axle ( 13 ), and an auxiliary drive train ( 14 ) which is driven by the transmission output shaft ( 10 ), and which has the auxiliary drive axle ( 15 ) for driving the auxiliary drive axle ( 16 ), a clutch unit ( 17 ) for the switchable connection of the auxiliary drive axle ( 15 ) to the transmission output shaft ( 10 ) and a transmission gearing ( 18 ), with a transmission ratio selected so as to adapt a drive transmission ratio of the auxiliary drive train ( 14 ) to a different axle drive transmission ratio of the main drive train ( 11 ), the axle drive ( 12 ) of the main drive train ( 11 ) and the auxiliary drive axle ( 15 ) of the auxiliary drive train ( 14 ) having different transmission ratios, a concept of adapting the auxiliary drive train for drive train arrangements of vehicle models with different axle ratios by changing a drive ratio of the main drive axle ( 13 ) and adapting the transmission ratio of the transmission gearing ( 18 ) between the main drive train ( 11 ) and the auxiliary drive train ( 14 ) to accommodate the different main axle drive transmission ratio so as to permit the use of the same auxiliary drive axle ( 15 ) for the auxiliary drive train in connection with a different main drive train ( 11 ).
