    Abstract: A castor includes a castor body, a first bushing mounted on a top of the castor body, a bearing mounted in the first bushing, a top cover mounted on the top of the castor body to cover the first bushing and the bearing, a second bushing mounted on a bottom of the castor body, and an upright shaft in turn extending through the top cover, the bearing, the castor body and the second bushing. Thus, the distance between the top cover and the second bushing is increased so that the bearing and the castor body can bear a heavier load. In addition, the distance between the top cover and the second bushing is increased so that the upright shaft and the second bushing can bear a greater rotational force.

    Abstract: A wheel includes a rim having inner and outer flanges. A first end of each flange is positioned axially outwardly relative to the second end. A pair of bead seats are positioned one adjacent each flange, and each has an axially outer end connected to a second end of its flange by a flange connecting portion, and an axially inner end connected to one of a pair of side parts. Each side part is positioned between a central well and one of the inner and outer flanges, and connected to the well by a well connecting portion. The outer end of each bead seat is positioned radially outwardly relative to bead seat inner end. At least one of the flanges includes an extended portion which extends radially inwardly, such that a free end of the extended portion is positioned radially inwardly relative to the first end of the respective flange.

    Abstract: This invention is related to a wheel securing structure of trucks. The securing structure mainly install iron screwshaft liners on keyholes of the mounting parts of the aluminum rims. The bolts of the assembling part correspondingly penetrate the holes of the screwshaft liners each. A first folded edge and a second folded edge are formed on two terminals of the screwshaft liners to respectively insert into the conical pits of the mounting part of the rims. The nuts screw onto the bolts of the assembling part to secure the rim onto the assembling part and the nuts. When the trucks pass bumping roads, the relative motion, caused by vibrations, is occurred between the rims and the assembling part. Therefore, friction is generated between the wheels and the bolts, as well as the nuts and the terminal surfaces of the assembling part. The screwshaft liner is used to let the friction above act on the screwshaft liner. Therefore, the soft aluminum rim will not be directly rubbed by the bolts, nuts, and the assemble part to be damaged. Accordingly, the aluminum rim can be suitable for the trucks and other heavy vehicles.

    Abstract: A hollow twin-wheel caster structure of a luggage includes a wheel seat for coupling to the bottom of the luggage, the wheel seat having a horizontal inner annular hole; a hollow shaft unit inserted in the inner annular hole, two ends of the hollow shaft unit extending out of two sides of the inner annular hole to form a pair of coupling portions, the center of the hollow shaft unit being formed with a hollow portion communicating with the two ends of the hollow shaft unit; two plastic wheels fitted on the coupling portions; at least one bearing fitted on the hollow shaft unit; and a support member plugged into the hollow portion of the hollow shaft unit, the support member leaning against an inner wall of the hollow portion to prevent the hollow shaft unit from being compressed and deformed.
