Title:
FRONT WHEEL STEERING MECHANISM IN CENTER HUB STEERING
Document Type and Number:
WIPO Patent Application WO/2021/064983
Kind Code:
A1
Abstract:
[Problem] Pertaining to a front wheel steering mechanism in center hub steering, the purpose is to, inter alia, provide a front wheel steering mechanism in which front wheels can be mounted favorably and feasibly particularly even if sufficient offset is taken, optimum geometry is set, and desired steering performance, etc., is ensured, and further in which rolling performance and fuel efficiency can be dramatically improved without the outer diameter of a hub bearing increasing and without increasing bearing friction. [Solution] A front wheel steering mechanism 1 is characterized by comprising an inner wheel hub 2, a left outer wheel hub 3a, a right outer wheel hub 3b, a pair of rolling bearings 4, 4 positioned respectively between the inner wheel hub 2 and the left outer wheel hub 3a and between the inner wheel hub 2 and the right outer wheel hub 3b, and a front shaft 5, the left outer wheel hub 3a and the right outer wheel hub 3b being separable to the left and right along a rotational axis direction and the left and right outer wheel hubs being rigidly coupled.
