Abstract
In a motor vehicle drive train device with a transmission output shaft, a main drive train driven by the transmission output shaft, which has an axle drive for driving a main drive axle, an auxiliary drive train driven by the transmission output shaft, which has an axle drive for driving an auxiliary drive axle, a clutch unit for the switchable connection of the axle drive to the transmission output shaft, the axle drive of the main drive train and the axle drive of the auxiliary drive train have different transmission ratios and a transmission gearing for adapting a drive transmission ratio of the auxiliary drive train to a drive transmission ratio of the main drive train is provided.
Claims3
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 an axle drive (15) for driving the auxiliary drive axle (16), a clutch unit (17) for the switchable connection of the axle drive (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 drive transmission ratio of the main drive train (11), the axle drive (12) of the main drive train (11) and the axle drive (15) of the auxiliary drive train (14) having different transmission ratios.
