Abstract: Embodiments disclosed herein may be used to provide aerodynamic quarter fender assemblies. Panels may be rigidly or hingedly attached to existing quarter fenders or may be used in lieu of an existing quarter fender. Embodiments may provide improved fluid flow control across the transition zone between the tractor and the trailer, but may be easily moved into a stowed position to allow access to areas of the truck.
Abstract: Aerodynamic wheel covers may include a hub assembly coupled with a hub of a large vehicle, such as a truck. A base assembly may be coupled to the hub assembly, and a disk assembly may be coupled with the base assembly such that removal and installation of the disk assembly may be accomplished without tools.
