PURPOSE:To make each member settable on the same axis so accurately and stably, by connecting a flywheel, rotatably for an overrun, to an output shaft being supported rotatably on an axle on this shaft, while fitting an input member in a boss at the center of a wheel hub. CONSTITUTION:A connecting flange 113 is tightly attached to an input member 75 of a speed-up gear unit 45 with a screw 114. This connecting flange 113 is locked to a partition wall 8b inside a hub 8 by a connecting ring 116 and a bolt 117. At this time, this bolt 117 is pierced through from the opposite side to the partition wall 8b. On the other hand, an output shaft 42 is supported on a tubular shaft 24 locked to the top of an axle 10 via a needle bearing 41. And, a flywheel 72 is rotatably connected to this output shaft 42 via a cam mechanism 73 on this shaft 42. With this constitution, the input member 75, the output shaft 42 and the flywheel 72 are all accurately and stably set up on the same axis of the axle. In this connection, the setting bolt 117 is designed to be attachable or detachable in itself without utterly receiving any interference from the speed-up gear unit and a sensor so that maintenance is made yet better. |
