Abstract
A wheel hub that provides a wheel that is free-wheeling in both directions of turning and is constructed to provide low rolling resistance, greater load carrying capacity and is more reliable that earlier hubs. The hub includes separate bearing systems for supporting, respectively, radial loads as perpendicular to a road surface, and axial loads as are side loads directed into the hub. The separate bearing systems include a pair of radial bearings for supporting radial loads, with each radial bearing of the pair mounted at each hub end to receive an axle fitted therethrough, and a pair of thrust bearings for supporting axial loads, with each thrust bearing of the pair mounted at a hub end, between the radial bearings outer surfaces and an axle mounting to a frame.
Claims8
A hub for a wheel that is free-wheeling comprising, a cylindrical hub body that is open therethrough that includes means for mounting a wheel;
- cavities formed in said cylindrical hub body that are adjacent to opposite ends of said cylindrical hub body for seating radial bearings;
- a pair of radial bearings each having inner and outer races with bearing means journaled therebetween, and each of which said inner races is open therethrough to pass an axle;
- a straight axle for fitting through each said radial bearings inner race;
- a pair of thrust bearing means, one each for sliding along said axle to have an inner face thereof in contact with an outer surface of said radial bearing;
- and cap means, each for securing over one axle end and engaging an outer face of one of said thrust bearing means.
