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.

A rim includes a rim body and a spoiler portion. The rim body is annular and has two opposite side surfaces connected by an intermediate portion. Each surface has a radial inner portion located on a radial inner side and a radial outer portion located on a radial outer side. The radial outer portion has an extension portion and a radial outer periphery at the outermost side. The extension portion is extended toward the radial outer side from a connecting portion between the radial outer portion and the intermediate portion. The spoiler portion has a plurality of spoiler profiles concavely formed on the radial outer portion of at least one of the two side surfaces. At least one of the spoiler profiles is partially disposed on the extension portion without forming any undulation on the radial outer periphery.

Implementations disclosed and claimed herein provide a wheel cover system. In one implementation, an inward force exerted against a wheel cover of the wheel cover assembly in an inward direction towards the hub is received. The inward force overcomes a spring bias of a spring of the receiver and translates the wheel cover assembly in the inward direction. A first rotational force rotating the wheel cover assembly in a first direction is received. The first post guides and engages the first hook, and the second post guides and engages the second hook during rotation. A first positive feedback is generated in response to the inward force and the first rotational force. The wheel cover assembly is releasably locked to the receiver by translating the wheel cover assembly in the outward direction using an outward force generated by the spring bias. The outward force provides a second positive feedback.

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 vehicle wheel, including a rim, a hub, and a plurality of spokes, a first anchor to connect one of the spokes to one of the rim and hub at a connection interface. One of the spokes is pre-tensioned by a pre-tensioning means. The first anchor may be manipulated between: (i) a released orientation where the connection interface is longitudinally released from the spoke to permit independent longitudinal displacement therebetween; and (ii) an engaged orientation where the connection interface is longitudinally connected to said spoke to limit independent longitudinal displacement between the two and to maintain the pre-tension of said spoke. The pre-tensioning means is discreet from the first anchor.

An arrangement of wheels for a bi-directional vehicle may decrease the drag coefficient for the vehicle regardless of a direction of travel of the vehicle. A pair of wheels, each wheel of the pair having a configuration of fins to promote a desired aerodynamic effect, when located at a leading end of the vehicle promotes airflow laterally outboard of the vehicle body. In contrast, the same pair of wheels, when located at a trailing end of the vehicle promotes airflow laterally inboard of the vehicle body.

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.

An airflow adjusting apparatus to be installed in a vehicle includes an airflow generator and a controller. The airflow generator is provided on an inner surface of a wheel house or on a wheel. The wheel house provides a wheel containing section of a vehicle body. The wheel is contained in the wheel containing section. The airflow generator is configured to generate an airflow that flows from the wheel containing section toward outer side in a vehicle widthwise direction. The controller is configured to control the airflow generator.

An aerodynamic bicycle rim comprising: a circumferential outer portion comprising a circumferential outer surface, the circumferential outer portion adapted to seat a bicycle tire; a nose; and a set of sidewalls, each sidewall extending radially from the nose of the aerodynamic bicycle rim to a corresponding transition to the circumferential outer surface to form a rim body having a maximum rim body width that is greater than a maximum width of the bicycle tire. The aerodynamic bicycle rim is operable to seat the bicycle tire so that the aerodynamic bicycle rim and the bicycle tire form an asymmetrical cross-sectional shape.

A cover for a rim of a wheel of a vehicle. The cover, with fastening of the cover on the rim, can be arranged in at least partially overlap with a through opening of the rim delimited in the circumferential direction of the rim by respective spokes of the rim, whereby the through opening can be at least partially covered by the cover. The cover is directionally formed and has at least two slats, which delimit at least one channel arranged between the slats, through which air can flow in the installed position of the cover diagonally to a plane extending perpendicularly to the axial direction of the rim. The slats at least partially mutually overlap with respect to the installed position of the cover in the circumferential direction of the rim and along the axial direction of the rim.
