DETAILED DESCRIPTION

[0021] Referring now to FIGS. 1-2, a commercial vehicle wheel cover is generally designated 10, and comprises a wheel cover 12, a front side 14, a back side 16, handles 18 and 20, and cam latch assemblies 22 and 24. The wheel cover 12, is generally round and dome-shaped. The front side 14, consists of handles 18 and 20, and hinge points 30 and 32, for lifting the handles to the open position and lowering to the closed position. The cam latch assemblies are fixed in the installation position with the handles 18 and 20, in the closed position as shown in FIG. 2. When the handles 18 and 20, are in the lifted or open position the cam latch assemblies are free to rotate about the cam latch axes 34 and 36, for installation and removal purposes.

[0022] The wheel cover 12 can be made from a polymeric material by a molding process, or it can be made from a metallic material by a stamping process. The cam latch assemblies 22 and 24 can be made from polymeric materials by a molding process with the exception of the spring, roll pin, and E-clip which are generally made from metallic materials, preferably stainless steel.

[0023] Referring to FIG. 3, one of the two cam latch assemblies is generally designated 80, and consists of a number of components including a handle 82, a roll pin 84, a hinge point 86, a spacer 88, a shaft 90, a spring 92, a cam 94, a washer 96, and a E-clip 98. When the handle is in the closed position as shown in FIG. 3, the spring is compressed and the assembly is restricted from rotation and lateral movement. The cam 94, is locked into the collar 100, via a set of radial blades which are received by the collar in the interlock location 102, which fixes the cam assembly and, thus, the wheel cover 12, to the collar assembly. When the handle 82, is lifted the wheel cover 12, shifts upward away from the collar and the cam assembly is free to rotate about the cam latch axis 104 for installation and removal purposes.

[0024] Referring to FIGS. 4-7, the commercial wheel cover 12, interlocks with a collar assembly for retention on the axle hub. The collar assembly consists of two collars, 130 and 132, and is designed to fit over and cradle the axle hub flange. The collar assembly is installed on the axle hub flange by rotating the assembly open via the collar rotation axis 138, and then closing the collars around the axle hub flange as shown in FIG. 7. The assembly is then secured to the axle hub flange by installing a latch 140, onto the first collar 130, and then over-center latching onto the second collar 132. When installed the latch holds a compressive force on the axle hub flange securing the collar assembly to the wheel.

[0025] The user installs the wheel cover assembly to the collar assembly by lifting the handles 18 and 20, about the hinge point 86 and rotating 90 degrees about the axes 34 and 36. The user then lifts the wheel cover into position and rotates the handles back 90 degrees. Once engaged with the collar assembly via the interlock locations 134 and 136, the handles are lowered about hinge point 86 completely into the wheel cover. The assembly is attached improving the overall aerodynamic shape of the wheel as shown in FIG. 8.

[0026] While particular embodiments of the present invention have been illustrated and described herein, it will be appreciated by those skilled in the art that changes and modifications may be made thereto without departing from the invention in its broader aspects.
