摘要： This invention relates generally to wheeled luggage, and particularly to wheeled luggage with one or more controlled wheels for improved tracking and steering control of the luggage case when it is in motion. The invention provides a support structure for a luggage case comprising a plurality of spaced parallel wheels and at least one biasing element that is operable up to a certain torque to releasably restrain the angular movement at least one wheel to at least one angular position with respect to the base. Conveniently, the at least one angular position corresponds to a desired direction of travel.
