Apparatuses, systems, and methods are provided for improving fuel efficiency of a vehicle using a mountable wheel cap coupleable to a wheel. The mountable wheel cap includes a center section and an outer section. The outer section includes a plurality of tabs extending outwardly from the center section, and at least one gripper section coupled to at least one of the plurality of tabs, the at least one gripper section including a gripper configured to be placed in contact with the at least one of the outer section and/or the outer lip to secure the mountable wheel cap to the wheel.

Wheel center caps and related methods are disclosed herein. An example wheel center cap includes a body, a first protrusion extending radially outward from the body, and a second protrusion extending radially outward from the body. The first and second protrusions define a gap therebetween. The example wheel center cap includes a leg disposed in the gap and coupled to the body. The leg includes a foot. The foot extends radially outward relative to the body. The foot includes a chamfered face facing away from the body.

An air deflection ring that is configured to be attached to a wheel of a motor vehicle that includes a barrel including a cylindrical inner surface and an opposing cylindrical outer surface, a plurality of spokes that are each separated by an opening and attach the barrel to a center of the wheel. The air deflection ring includes a cylindrical mounting ring that is configured to be fixed to the cylindrical inner surface of the barrel, and an air deflection flange that extends radially inwardly toward the center of the wheel from the cylindrical mounting ring. The cylindrical mounting ring is configured to be fixed to the cylindrical inner surface of the barrel at a location positioned immediately adjacent to the plurality of spokes, and the air deflection flange is configured to direct a flow of air away from the openings during rotation of the wheel.

A wheel of a vehicle, in particular a motor vehicle, has a rim, a hub portion, and at least two spokes connecting the hub portion to the rim. At least one free space between the spokes is covered at least in part by a substantially planar covering element. The covering element is produced from two different material layers.

A wheel and tire assembly for a mobile vehicle in accordance with the present invention includes an inner central rim, a flexible ring mounted on the inner central rim, and a spoke structure extending between the inner central rim and the flexible ring. The spoke structure defines a plurality of cavities and alternating radially extending openings disposed concentrically about the inner central rim and allowing the flexible ring to deflect under load. The spoke structure further defines a plurality of triangular openings disposed at the flexible ring and between the cavities and the inlet openings.

A wheel with flexible spokes, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength.

A spring-force adjustable, height-adjustable industrial caster assembly including a mounting plate, a swivel housing that swivels relative to the mounting plate, and a spring assembly having components that are moveable relative to the swivel housing to controllably alter spring deflection and/or caster wheel height, which components can be adjusted by accessing the height-adjustable industrial caster assembly from above, eliminating the need to raise a pallet truck or other moveable assembly to which the caster assembly is coupled, away from the floor to be able to access and adjust the industrial caster assembly.

A wheel caster comprising a roller, and a two piece socket, wherein the two piece socket comprises a top housing, having a concave cavity to accept the roller in a freely rotatable configuration, a stem, to be inserted inside a leg of an object, and a bottom housing comprising an opening to allow a portion of the roller to extend below the bottom housing allowing the roller to contact a surface.

A wheel assembly comprising a wheel disk and a tread member disposed around the wheel disk. The wheel disk can have a substantially conical shape when in an unloaded state, but be flexible such that it can deform under load to optimize and/or maximize contact area between the tread member and a driving surface.

The present disclosure relates to a caster, having a housing, having an axle pin which is arranged in a housing opening which is oriented substantially horizontally, and on which at least one wheel is mounted, having, at the top, a pin opening oriented substantially vertically, for receiving a pivot pin, and having a braking device which brakes the at least one wheel, wherein the housing opening for the axle pin allows limited vertical displaceability of the axle pin and the braking device comprises at least one resilient housing part which acts on the axle pin. In order to provide a mechanically reliable braking device, the braking device is additionally provided with at least one spring element which cooperates with the at least one resilient housing part and amplifies the effect of its braking force and/or increases the mechanical load-bearing capacity of the at least one resilient housing part.
