A locomotion assembly is provided, suitable to be used in a vehicle. The locomotion assembly comprises a frustum-conical structure comprising at least one flexible member having a frustum-conical surface extending between its relatively narrow and wide ends along a frustum-conical axis, the frustum-conical member being reversibly deformable from its biased rounded shape corresponding to a frustum-conical shape in which its side elevation is circular into a deformed frustum-conical shape in which its side elevation is non-circular. The frustum-conical structure may serve for supporting at least one surface-engaging member convertible between a round wheel-like configuration, in which its side elevation is substantially circular, and a deformed configuration, in which its side elevation is non-circular and in which a larger portion of the surface-engaging member is in contact with a movement surface.
A locomotion assembly for a land vehicle, the locomotion assembly comprising a flexible, elastomeric ground-engaging member configured as a wheel having an essentially circular shape with a ground-engaging surface with first and second circumferential sides corresponding to first and second sides of the locomotion assembly, wherein the first and second sides of the locomotion assembly comprise respectively first and second circular, substantially V-shaped, grooves arranged with opposite symmetric orientation with respect to a rotation axis of the locomotion assembly, each of the V-shaped grooves having first and second frustum conical walls defined by surfaces of first and second frustum-conical members of a pair, the frustum-conical members of the pair comprising a plurality of rigid spikes, the first and second sides of the locomotion assembly with said grooves providing radial compression of the locomotion assembly by reversible deformation of the first and second grooves, thereby permitting reversible deformation of the ground-engaging member from a substantially circular shape of the wheel to a deformed shape in which a larger portion of the ground-engaging surface is in contact with a movement surface, such that the deformed shape of the ground-engaging member provides a larger footprint of the locomotion assembly.
A locomotion assembly for a land vehicle, the locomotion assembly comprising a flexible, elastomeric ground-engaging member having configured as a wheel having an essentially circular shape with a ground-engaging surface with first and second circumferential sides corresponding to first and second sides of the locomotion assembly, wherein
A wheel for a land vehicle comprising an inflatable rubber tire defining an enclosed fluid-pressure holding space with a circumferential ground-engaging member, having a ground-engaging surface with first and second sides corresponding to first and second sides of the wheel, wherein the first and second sides of the wheel comprise respectively first and second circular, substantially V-shaped, grooves arranged with opposite symmetric orientation with respect to a wheel rotation axis, each of the V-shaped grooves having first and second frustum conical walls defined by surfaces of first and second frustum-conical members of a pair, the frustum-conical members of the pair comprising a plurality of rigid spikes, the first and second sides of the wheel with said grooves providing radial compression of the wheel by reversible deformation of the first and second grooves, thereby permitting reversible deformation of the ground-engaging member from a substantially circular shape to a deformed shape in which a larger portion of the ground-engaging surface is in contact with a movement surface.
