A transmission for a vehicle comprises a mechanical multi- step gearbox 6, in front of which a hydraulic torque converter 5 is arranged. Arranged in turn in front of the torque converter 5 is a planetary gear which divides the torque from a drive engine equally to a differential gear. Part of the torque can in this connection be transmitted mechanically to the multi-step gearbox 6 and part can be transmitted hydraulically via the torque converter 5. By virtue of the fact that only part of the torque is transmitted via the torque converter 5 and that the planetary gear 4 acts as an overdrive, the vehicle can achieve a relatively high speed from starting before changing is required in the multi-step gearbox 6. This makes it possible for the changing procedure to be automated by simple means, it being possible to change without having to use a conventional clutch to interrupt transmission before changing. <IMAGE> |
