Abstract
A front wheel steering mechanism in a center hub steering system. The mechanism comprising an inner wheel hub, an outer wheel hub, paired rolling bearings positioned between these inner and outer wheel hubs, a front shaft, a hub steering bracket attached to outside of the front shaft, and a hub steering shaft. The inner wheel hub is attached to the hub steering bracket so as to freely rotate about the hub steering shaft as an axial center. The outer wheel hub is configured of a left outer wheel hub and a right outer wheel hub. These left and right outer wheel hubs are rigidly coupled or are coupled via a plurality of wire spokes to a rim.

A front wheel steering mechanism in a center hub steering system, the mechanism comprising an inner wheel hub, an outer wheel hub, paired rolling bearings positioned between these inner and outer wheel hubs, a front shaft, a hub steering bracket attached to outside of the front shaft, and a hub steering shaft, wherein
- the inner wheel hub is provided with a first hub-steering-shaft hole for having the hub steering shaft inserted thereinto, at rear of the front shaft and at a position a predetermined distance away from the front shaft,
- the hub steering bracket is provided also with a second hub-steering-shaft hole for having the hub steering shaft inserted thereinto,
- the hub steering shaft penetrates through the first and the second hub-steering-shaft holes,
- the inner wheel hub is attached to the hub steering bracket so as to freely rotate about the hub steering shaft as an axial center, and
- the outer wheel hub is configured of a left outer wheel hub and a right outer wheel hub separable to left and right along a rotation axis direction, and these left outer wheel hub and right outer wheel hub are rigidly coupled.
