The gearbox (4) has a shaft (7) connected to a heat engine (2), and another shaft (8) connected to wheels (5) of a vehicle. A gear comprises a set of idler gears (15-17, 23, 24) mounted on one of the shafts. A friction unit (31) is associated with a transmission ratio, and frictionally transmits torque in a temporary manner during changing of the gear ratio via the transmission ratio. A set of sleeve claws (27 - 29) and the idler gear are automatically ejected, where the automatically ejected claws eject a preceding ratio, when a new ratio is engaged without breaking torque. Independent claims are also included for the following: (1) a method for changing a gear ratio rising with positive torque for passing a manually controlled six-speed gearbox from initial ratio to final ratio (2) a method for changing the gear ratio decreasing with positive torque for passing the manually controlled six-speed gearbox from initial ratio to final ratio (3) a method for changing the gear ratio rising/decreasing with negative torque for passing a manually controlled six-speed gearbox from initial ratio to final ratio. |
