Abstract: The present disclosure provides a Mecanum wheel. The Mecanum wheel includes a spoke, a hub, and a plurality of rollers disposed on an outer edge of the spoke. The spoke includes a receiving space to house the hub. The Mecanum wheel further includes a cushioning member, one end of the cushioning member being connected to the spoke, and the other end of the cushioning member being connected to the hub. In response to receiving an impact force, the cushioning member deforms to cause a displacement change of the hub relative to the spoke.

Abstract: Wheel with an in-wheel suspension system, and suspension member thereof. Wheel includes: stationary member including an axis, rotary member rotatable about the axis, and selective suspension system. The selective suspension system has at least one suspension member positioned between the stationary member and the rotary member, thereby providing a fixed distance therebetween, and retains the fixed distance when stressed up to a threshold value, and recoverably alters the fixed distance when stressed over the threshold value. The suspension member includes: cylindrical housing, piston slidably movable in the cylindrical housing, and compression spring whose first end is connected to the piston and second end is connected to the housing. The compression spring, when fully relaxed or compressed under the threshold value, maintains the housing and piston at a normally fixed distance. Applicable to wheelchairs and bicycles, among other self-propelled and powered vehicles.

Abstract: A wheel connectable to a vehicle. The wheel includes a stationary member having an axis, a rotary member rotatable about the axis, and at least one support member positioned between the stationary member and the rotary member, thereby providing a normally fixed distance therebetween. The support member is adapted to retain the distance when stressed up to a threshold value and to recoverably alter the distance when stressed over the threshold value.

Abstract: A wheel assembly for traversing a path along a ground surface having a layer of soil, the wheel assembly comprising a central support and an airless flexible covering mounted on the central support and having a plurality of rigid sections and a plurality of flexible sections. The outwardly protruding spokes urge the rigid sections into the layer of soil when the rigid sections contact the ground surface. The flexible sections flex inwardly when the flexible sections contact the ground surface so that the rigid sections and the flexible sections cooperatively form a corrugated pattern in the ground surface without urging the soil to side margins of the airless flexible covering, the corrugated pattern having a plurality of valleys formed by the rigid sections and a plurality of peaks formed by the flexible sections.

Abstract: A rubber-sprung wheel for rail vehicles includes a wheel tire which is connected to a wheel rim by a rubber insert that is formed by two flat rings that are arranged so as to be essentially vertical in relation to a wheel axle. The two flat rings are held, under considerable axial prestress, between an inner circumferential middle web of the wheel tire and two outer flanges of the wheel rim. At least one of the flanges is seated on the wheel rim with an interference fit that is designed as a conical press fit, such that a cone of the flange in a stress-free state has a lesser conicity than does a cone of the wheel rim, and in a pressed-on state rests on an entire surface against the cone of the wheel rim, at an even surface pressure across an entire width of the interference fit.
