Abstract

The gearbox (10) comprises a first device (13) rotatable about a first axis of rotation (ri) and arranged to be coupled for rotation with a primary shaft, wherein the device (13) includes a pair of radial rods (14) radially movable between an extended position and a retracted position; and a second device (18) rotatable about a second axis of rotation (r2) parallel to the first axis (r1) and capable of being coupled for rotation with a secondary shaft. The second device (18) can be moved relative to the first device (13) in a transverse direction (t), perpendicular to the axes of rotation (r1, r2), between a first position in which the two axes of rotation (r1, r2) are aligned and the two devices (13, 18) rotates at the same angular velocity and a plurality of selectable predetermined positions, each corresponding to a predetermined gear ratio, in which the two axes of rotation (r1, r2) are spaced accordingly. By virtue of such an arrangement, the gear shifting operation can be performed without interruption in the transmission of the torque between the primary and secondary shafts.
