Abstract: A wheel suspension system, comprising, a wheel rim, a plurality of adaptors equidistantly mounted on inner periphery of the wheel rim, a plurality of suspension curved elastic members having drafted ends configured to be circumferentially and linearly disposed into the adaptor along the wheel rim, and a multi-layered hub having a plurality of interlocked holders away from its centre towards the wheel rim for interlocking the elastic members at the centre. The wheel suspension system is cost effective for both users and manufacturers, user friendly, comfortable, easy to assemble or disassemble, comfortable and provides safety in cases of accidents.

Abstract: Cart bumpers and carts including cart bumpers are described. In aspects, a cart bumper includes an outer contact wall, an inner rim, and a plurality of spokes extending from the inner rim to the outer contact wall, each spoke of the plurality of spokes defining a respective path. The outer contact wall and the plurality of spokes are configured to collapse in response to a mechanical force applied on the outer contact wall above a predetermined threshold force.

Abstract: A wheel hub includes a hub flange that extends about the wheel hub. The hub flange includes a removed section that is aligned with a camshaft assembly. An insert is used to fill the removed section. The insert is selectively removable from the hub flange to provide access to the removed section such that the camshaft assembly can be removed from a brake assembly via the removed section without having to remove the wheel hub from an axle assembly.

Abstract: A vehicle wheel is disclosed that is made up of a plurality of extrusions. A rim may be provided in either a cylindrical form or in the form of a series of arcuate segments. Rim attachment brackets are provided to secure spokes to the rim. Spokes are provided between the rim and a hub that defines an axle aperture. The rim is roll formed to form tire retention beads and the outer surface of the rim that's in the abstract.

Abstract: In the wheel structure according to the invention, at least one and preferably several profile elements (2.1) are used for the transmission of forces between hub (1) and rim (3). Said parts (1.2, 1.3) are combined or combinable into an intrinsically stiff structure. The structure is particularly suitable for car wheels.
