A vehicle transmission, particularly for industrial and agricultural vehicles, includes a speed change gearset (gear and range) and a central differential for distributing the gearset output to the front and rear axles of the vehicle. The central differential is formed of a Ravigneaux gearset to reduce the dimensions of the transmission and to minimize the costs and technical resources required to produce it. The Ravigneaux gearset distributes the torque of a gear output shaft to the front and rear axles according to the ratio of the two Ravigneaux sun gear diameters. Preferably, the end stage of the speed change gearset is formed by a further Ravigneaux gearset, and the planet carriers of both Ravigneaux gearsets are formed as a common structural member carrying the planets of both Ravigneaux gearsets.
