Abstract
Speed transmission 1 for a vehicle, comprising an external box 6, a main assembly 2 whose input shaft 7 is able to take the motion from an engine of the vehicle and whose primary shaft 8 can be connected at an angle to the input shaft via a plurality of gear pairs 24-32, defining different transmission ratios, and an auxiliary epicycloidal assembly 3 comprising a sun gear 23, coupled at an angle to the primary shaft 7, a train carrier 40, integrated at an angle with an output shaft 47 of the transmission and carrying a plurality of planetary gears 38 meshing with the sun gear 23, and an external crown meshing with the planetary gears 38 and which can be coupled selectively to the box of the transmission 6 and to the train carrier 40; the sun gear 23 is floating in radial direction and the train carrier 40 is rigidly supported relative to the box 6 on opposite sides relative to the sun gear 23 itself. <IMAGE>
