<p>The switch unit (22) has a hub axle (1), an actuator (3), a hub bushing (5) and a gear system, preferably at least a planetary gear system. A remotely operated control unit for changing gears has at least one free wheeling coupling to change the power flow to another coupling. The control unit has a switch unit comprising a switch sleeve (21) and a switch bushing (20), which each have profiles on the side facing the free wheeling coupling that engage the gears of the coupling under load.</p> |
