Vehicle transmission consisting of a basic gearbox (1) and a supplemental gearbox (11), comprising a planetary gear set (23) with a direct drive mode and a crawl mode, a differential (31) between two front wheel drive axles (35,36) and an angle gear set (39,41) for transmitting torque to a rear axle differential. Shifting between direct drive mode and crawl mode is achieved with an axially displaceable engagement sleeve (17) which, in direct drive mode, transmits torque from the basic gearbox directly to the differential between the front axles and in the crawl mode transmits torque to the sun gear (26) of the planetary gear set. |
