Between 112.Specifically, primary speed-down driven pulley 122 is provided with axle journal, and inner ring and the axle journal of clutch shaft bearing group 160 are fixed, and first
The outer ring of bearing group 160 is fixed with housing department 111 with sleeve part 112, and thus primary speed-down driven pulley 122 can be with opposite case
110 rotations.It is understood that the quantity of the bearing in clutch shaft bearing group 160 is not specifically limited, in clutch shaft bearing group 160
Bearing can be two or more.
Because primary speed-down driven pulley 122 is multiple, therefore support shaft 130 and multiple uniform primary speed-down driven pulleys
122 coordinate, it is ensured that the stability under loading of support shaft 130, Torque distribution is average, reduce the load to clutch shaft bearing group 160, improve
The service life of clutch shaft bearing group 160.
Wheel rim connector 140 is supported on sleeve part 112 by second bearing group 170, thus in the second reduction driven wheel
When imparting power to wheel rim connector 140, wheel rim connector 140 can be rotated with opposite case 110, and then ensure travelling wheel
Stable operation.
