<p>Gear-change mechanism consisting of an input shaft (EE) on which is coaxially arranged a series of transmission assemblies (C<SUB>1</SUB>), (C<SUB>2</SUB>), (C<SUB>3</SUB>), (C<SUB>4</SUB>); an output shaft (ES) on which is coaxially and securely arranged a series of driven gears (A<SUB>1</SUB>), (A<SUB>2</SUB>), (A<SUB>3</SUB>), (A<SUB>4</SUB>); and a brake (F<SUB>1</SUB>), (F<SUB>2</SUB>), (F<SUB>3</SUB>), (F<SUB>4</SUB>) for the brake disc (1) of each transmission assembly (C<SUB>1</SUB>), (C<SUB>2</SUB>), (C<SUB>3</SUB>), (C<SUB>4</SUB>), such that, by means of electronic control, it suffices to operate one of the brakes in order to place in a driving relationship the corresponding transmission assembly thereof and the corresponding driven gear thereof, the remaining ones turning idly.</p> |
