ABSTRACT:
A transmission comprises transmission shafts connected to right and left wheels, respectively. Each transmission shaft has a side clutch and a side brake. The side clutch includes clutch balls movable radially of the transmission shaft between a clutching position engaged with a first engagement portion of the transmission shaft and a declutching position radially retracted from the transmission shaft. The side brake includes brake balls movable radially of the transmission shaft between a braking position engaged with a second engagement portion of the transmission shaft and a releasing position radially retracted from the transmission shaft. A shifter sleeve is axially movably mounted on each transmission shafts. The shifter sleeve includes a first space for accommodating the clutch balls, a second space for accommodating the brake balls, and a projection for pressing the clutch balls and brake balls. The sleeve is movable between a position in which the projection presses the clutch balls into the first engagement portion, and a position in which the projection presses the brake balls into the second engagement portion with the clutch balls accommodated in the first space.
