The utility model discloses a wheel nut, including a nut body which the outside surface comprises of multiple identical arc surfaces. The arc surface is protruding outward, and the radius of the arc surface is larger than the circumscribed radius of the outside surface of the nut body. The utility model designs the existing square surface of the outer hexagon feature of the wheel nut as an arc surface, which the contact area between the wheel nut and the sleeve and the loading area of the wheel nut can be increased, and then the deformation and looseness of the wheel nut can be avoided effectively, and therefore the service life of the wheel nut can be improved.

An apparatus and method for holding a lug nut. The apparatus includes a base (150), a barrel (140), a lug nut engagement assembly (130), a plunger and a cam guide (170). The barrel (140) is coupled with the base (152) in a manner allowing the barrel (140) to move upwardly or downwardly within the base (150). The barrel (140) has an internal cam track portion (145). The lug nut engagement assembly (130) includes retractable fingers (132). The lug nut engagement assembly (130) is removeably affixed to the barrel (140). The plunger (160) is disposed within a portion of the lug nut engagement assembly (130), the barrel (140) and the cam guide (170). The plunger (160) has a tip for engagement with the retractable fingers (132). The cam guide (170) is disposed and moveable within a bottom portion of the barrel (140). The cam guide (170) has longitudinal rails (172) for engagement with the internal cam track (145) of the barrel (140).

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.

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.

A hub cap assembly includes a disc having a top surface and a bottom surface. A rim extends from the bottom surface. The hub cap assembly also includes at least one tire stem port disposed on the disc. Moreover, the rim comprises a cavity that receives balance media. In some embodiments, the hub cap assembly further comprises cooling fins, e.g., disposed about a circumference of the top surface. The cooling fins can direct cooling air to a corresponding tire, e.g., to cool a bead of the tire.

A fastener retainer includes at least one fastener cap and a hub. Each fastener cap can include a stop channel that encircles a bottom portion of a housing of the fastener cap, a base with cog members that encircle the housing, or a combination thereof. The hub has at least one port therein, where each port is associated with a corresponding fastener cap. At least one locking member is positioned on the hub. For instance, a locking member can be provided adjacent to each port. In use, each locking member constrains radial movement of a corresponding fastener cap inserted into the associated port, by disposing a projecting member into a space between adjacent cog members on the base of the corresponding fastener cap.

A wheel center cap ASSY (assembly) for a work vehicle includes a center cap attached to a hub of a wheel coupled to an axle and having a center axis, an adaptor including a cap attachment portion to which the center cap is attached and a plurality of flange portions disposed on the outer side of and along a circumferential direction of the center cap, and a coupling member for coupling the flange portions to the hub.

The present invention relates to a plurality of airfoil rim wings, and/or fan-like blades which may be flat or take the form of airfoil wings in a preferred embodiment are attached to an automobile's wheel rims for the extraction of air pressure buildup within the wheel wells during forward movement to improve overall performance, styling and brake cooling. The airfoil rim wings, and/or fan-like blades may either be adhered to a wheel surface or individually or collectively fastened to wheels' hub using open-ended lug nuts, and securing lug bolts. Further, the airfoil rim wings, and/or fan-like blades may be arranged to specific concavity and angel of attack using twistable beveled washers on both sides of the airfoil rim wings, and/or fan-like blades.

Described is a system (and method) for locating a center point of a lug nut for an automated vehicle wheel removal system. To improve the accuracy of the center point, the system may perform machine learning inferences using two-dimensional (2D) and three-dimensional (3D) image data. The system may process a 2D image to infer an initial center point, and potentially improve the accuracy by leveraging a 3D image. More particularly, the system may process a 3D image to infer a location of one or more edges (or edge points) around the perimeter of the lug nut and measure a set of distances between the initial center point and the located set of edges. The system may then refine (or adjust) the center point based on such measurements.
