Abstract
A drive for vehicles, especially a four-wheel drive for motor vehicles, with an engine installed transversely to the vehicle longitudinal axis whose output shaft is arranged axially parallelly to the input and output shafts of a change-speed transmission. An auxiliary power-divider gear having an intermediate differential gear is connected with the transmission output shaft; the transmission axis of the power-divider gear coincides with a vehicle axis, whereby the intermediate differential gear and the axle differential gear are adapted to be locked up by a clutch. The power-divider gear is constructed as spur gear-planetary gear transmission with an externally toothed planet gear carrier. The latter is operatively connected with a spur gear arranged on an axially parallelly arranged output shaft of the transmission. For the purpose of a power-divided axle drive, the planet gears of the transmission are in driving connection with a ring gear and a sun gear. The axle drive to a first vehicle axle takes place by way of the ring gear, and the further axle drive to a second vehicle axle takes place by way of the sun gear.
