Abstract
A cross-country vehicle comprising an all-wheel drive is driven by a reciprocating engine installed transversely close to the front axle and by means of a change speed transmission which is also disposed transversely in the front. From the change speed transmission, the drive torque flows onto a planetary transmission operating as a center differential. The ring gear of the planetary transmission drives the front axle; the sun gear drives a low-high change-over unit. The planetary transmission, the change-over unit and the wheel sets connected behind it are constructed such that, during the high operation, the major portion of the torque is available at the front axle, and, in the low operation, is available on the rear axle. The center differential can be locked in the high and in the low operation.
