Abstract: A transmission includes a sub-transmission mechanism (30), a variator (20) having lower shift responsiveness than the sub-transmission mechanism (30), and a controller (12) configured to carry out a coordinated shift for changing a speed ratio of the variator (20) in a direction opposite to a changing direction of a speed ratio of the sub-transmission mechanism (30) as the sub-transmission mechanism (30) is shifted so that a through speed ratio reaches a target through speed ratio. The controller (12) sets a target speed ratio of the sub-transmission mechanism (30) on the basis of the target through speed ratio and an actual speed ratio of the variator in carrying out the coordinated shift.

Abstract: A gear-shifting mechanism for vehicles has a crankcase (10), a gearbox (20) and a reserved room (30). Because the reserved room (30) is formed between a first case (11) of the crankcase (10) and a body (21) of the gearbox (20), a shift lever (14) can protrude out of the first case (11) and is mounted into the reserved room (30) to connect to a transmission between the crankcase (10) and the gearbox (20). Besides, the shift lever (14) also can protrude out of a second case (12) to connect to a transmission opposite to the gearbox (20). As a result, the shift lever (14) can output in two directions, applicable for the gearbox (20) in left or right of the crankcase (10). An engine connected to the gear-shifting mechanism can be adapted for various vehicles.
