Abstract
A drive arrangement for a motor vehicle includes two driven axles, wherein at least one of the axles can be connected and disconnected, with a variable speed transmission having at least one input shaft, two driven shafts, each driven shaft driving a respective axle, and several forward gears and optionally one reverse gear which can be switched via gear wheels and synchronous couplings. The drive arrangement can be easily switched between different drive modes by dividing the variable speed transmission into two sub-transmissions, of which one sub-transmission drives exclusively a first axle via a portion of the forward gears and the one driven shaft and the second sub-transmission drives both driven shafts via the remaining portion of the forward gears and optionally the reverse gear.
