## Background
FIELD
The present disclosure relates to wheel hubcaps and, more specifically, to an integral clamp hubcap for retention of the hubcap on a wheel.
BACKGROUND
Aircraft wheels may include a hubcap that is retained on the wheel with a retaining device such as a clamp. During maintenance operations the hubcap and retaining device may be removed to service and/or to remove the wheel. When removed, the hubcap and retaining device may be separate pieces that may be misplaced, increasing the risk of foreign object damage (“FOD”) and/or requiring replacement after loss.

DETAILED DESCRIPTION
The detailed description of exemplary embodiments herein makes reference to the accompanying drawings, which show exemplary embodiments by way of illustration and their best mode. While these exemplary embodiments are described in sufficient detail to enable those skilled in the art to practice the inventions, it should be understood that other embodiments may be realized and that logical, chemical and mechanical changes may be made without departing from the spirit and scope of the disclosure. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation. For example, the steps recited in any of the method or process descriptions may be executed in any order and are not necessarily limited to the order presented.
Furthermore, any reference to singular includes plural embodiments, and any reference to more than one component or step may include a singular embodiment or step.
Surface shading lines may be used throughout the figures to denote different parts but not necessarily to denote the same or different materials.
Vehicles that comprise wheels often include hubcaps that protect internal rotating components in the wheel, such as for example, bearings, bushings, and/or the like. The hubcap may be retained by a clamp that ties, couples and/or otherwise clamps the hubcap to the wheel. The hubcap and clamp may be removed to perform maintenance operations and/or the like. During these maintenance operations the clamp and/or hubcap are removed and place aside (e.g., set on the ground so that a technician may access the wheel or other structures to conduct the maintenance operation).
In various embodiments, the clamp may be any suitable structure, shape, and/or configuration suitable for retaining a hubcap on a wheel. For example, the clamp may be a v-clamp (e.g., a clamp having a substantially “v” shaped portion), a u-clamp (e.g., a clamp having a substantially “u” shaped portion), an o-clamp, a u-bolt (e.g., a bolt having a substantially “u” shaped portion), a band clamp, an asymmetric clamp, and/or the like.
The retaining devices described herein provide cost effective, reliable, and efficient mechanisms for creating hubcap/clamp assemblies. In various embodiments, the clamp and hubcap may be coupled or fixed together to form an assembly. In this regard, the assembly is less likely to be lost or displaced (e.g., kicked) during a maintenance operation, which reduces the risk of FOD in an aircraft operating environment. The assembly may be provided as a single line-replaceable unit (“LRU”), as opposed to multiple LRUs (e.g., for the clamp and hubcap, separately).
In various embodiments and with reference to FIG. 1, a vehicle such as an aircraft may comprise landing gear or a drive train with a wheel 110 and a hubcap 120. Hubcap 120 may be installable on wheel 110. Hubcap 120 may be retained and/or secured to wheel 110 with a clamp 130. Hubcap 120 and clamp 130 may be coupled to one another by a retaining device 140.
In various embodiments, retaining device 140 may be any suitable structure that is capable of coupling, attached, securing and/or otherwise joining hubcap 120 and clamp 130. For example, retaining device 140 may be a tab, a cable, a bond (e.g., a weld, a braze, an adhesive, and/or the like), a fastener (e.g., a screw, rivet, pin, and/or the like), and/or a bracket.
In various embodiments and with reference to FIG. 2A, clamp 230 may have a generally circular shape. Clamp 230 may have free ends (e.g., a first free end 231 and a second free end 233) that couple to one another when installed on wheel 110, as shown in FIG. 1, and/or hubcap 220. Free ends 231 and 233 may be coupled and/or held together with a coupling mechanism 232. For example, first free end 231 may comprise a bolt and second free end 233 may receive a nut (e.g., coupling mechanism 232 comprises a bolt and a nut). In this regard the bolt may be coupled to the nut to secure first free end 231 to the second free end 233, and similarly, secure and/or couple hubcap 220 to a wheel.
In various embodiments shown in FIGS. 2A-2C, a retaining mechanism, such as retaining mechanisms 240A through 240C may affix and/or fixedly attach clamp 230 to hubcap 220. In this regard, retaining mechanisms 240A through 240C may be fixedly attached to both clamp 230 and hubcap 220, but may allow movement between clamp 230 and hubcap 220 (e.g., where the retaining device is a wire or cable). Retaining mechanisms 240A through 240C may be installed at any suitable location of clamp 230 and/or hubcap 220. In this regard, retaining mechanisms 240A through 240C may be installed along a portion of the generally circular diameter such that free ends 231 and 233 are able to move sufficiently to surround the wheel diameter when the clamp 230/hubcap 220 assembly is installed on the wheel.
In various embodiments and with continued reference to FIG. 2A, the retaining device may be a tab 240A. Tab 240A may comprise a first end 241A and a second end 243A. The first end 241A may be attached to clamp 230 and the second end 243A may be attached to hubcap 220. For example, the first end 241A may be attached with a fastener or bond. Similarly, the second end 243A may be attached with a fastener or bond.
In various embodiments and with reference to FIG. 2B, the retaining device may comprise cable 240B (e.g., a wire, cord and/or the like). Cable 240B may comprise a first end 241B and a second end 243B. The first end 241B may be attached to clamp 230 and the second end 243B may be attached to hubcap 220. For example, the first end 241B may be attached with a fastener or bond. Similarly, the second end 243B may be attached with a fastener or bond. Cable 240B may be any suitable materials such as for example, a metal (e.g., aluminum, steel, titanium, and/or any other suitable metal or alloy), a polymer (e.g., nylon), a composite, and/or any other suitable material.
In various embodiments and with reference to FIG. 2C, the retaining device may be a bond 240C. Bond 240C may be a weld, braze, adhesive and/or the like bonding hubcap 220 to clamp 230. Moreover, bond 240C may couple and/or attach hubcap 220 to at least a portion of clamp 230.
In various embodiments and with reference to FIG. 3A, the retaining device may be a fastener 340D. Fastener 340D may be screw, rivet, pin, and/or the like. For example, fastener 340D may be configured to pass through a portion (such as an opening) of clamp 330 and engage hubcap 320. Similarly, fastener 340D may be configured to pass through a portion of hubcap 320 and engage clamp 330. In this regard, fastener 340D may attach or rigidly couple clamp 330 and hubcap 320 together such that they assembly is installable on wheel 310.
In various embodiments and with reference to FIG. 3B, the retaining device may be a bracket 340E. Bracket 340E may comprise a first end 341E and a second end 343E. The first end 341E may be attached to clamp 330 and the second end 343E may be attached to hubcap 320. For example, the first end 341E may be attached with a fastener or bond. Similarly, the second end 343E may be attached with a fastener or bond.
In various embodiments and with reference to FIGS. 4A-4B, clamp 430 may be any suitable shape or geometry. For example, clamp 430 may be asymmetric and/or may have a non-uniform or un-equal profile. In this regard, a first portion 431 of clamp 430 may be larger than a second portion 433 of clamp 430. First portion 431 may be coupled to or fixed to hubcap 420. Second portion 433 may be installable on wheel 410. Moreover, second portion 433 may be sized to be easily installed on wheel 410 and then tightened to secure hubcap 420 to wheel 410. Moreover, clamp 430 (e.g., first portion 431) may be coupled to hubcap 420 by retaining device 440 (e.g., a tab, a cable, a bond (e.g., a weld, a braze, an adhesive, and/or the like), a fastener (e.g., a screw, rivet, pin, and/or the like), and/or a bracket as described herein).
