Embodiments provide an aerodynamic fairing system that may comprise a base configured to mount to a vehicle, an arm coupled to the base at a proximate end and extending laterally, and a fairing mounted to the arm having an inboard and an outboard surface. The fairing outboard surface may provide an aerodynamic outer surface to direct flow to an angle to the rear. The arm may a fixed or adjustable length arm. The arm may provide a mounting area for a mud flap such that aerodynamic system may act as a mud flap hanger. Embodiments also provide an adjustable mud flap hanger.

A fully foldable mud flap has an upper flap section having a magnet permanently attached and a lower flap section having a magnet of the opposite polarity attached. The flap sections are connected by a hinge which allows rotation of the lower flap section in relation to the upper flap section, such that, in the retracted position, the lower flap section is parallel to and directly faces the upper flap section, with the magnets securing the flap sections in this position. The mud flap can be conveniently manually folded and unfolded, when desired.

An apparatus and method that can be used to repair a mud flap that has been torn off of the bolt that fastens the mud flap to the hanger bracket on a vehicle. The bolt and torn mud flap are removed from the hanger bracket and the apparatus is positioned over the upper edge of the mud flap where the bolt tore through. The bolt is then inserted through holes in the apparatus and the mud flap, and the assembly is reattached to the hanger bracket.

An apparatus and method for improving the safety and performance of an automobile in crash events is disclosed. The apparatus includes a front crash pad, rear crash pad, and a connection beam. Both crash pads and the connection beam are coupled to an automobile in such fashion as to absorb and dissipate energy by converting kinetic energy into strain energy.

A working vehicle may be provided that detects obstacles around a self-traveling tractor in a wide range, with reduced erroneous detection. A tractor may include a vehicle body including a front wheel and a rear wheel; a rear wheel fender covering the front and top of the rear wheel; a rear stay in a shape that extends along the rear wheel fender, a rear first obstacle sensor provided at the front of the rear stay; and a rear second obstacle sensor provided at the rear of the rear stay.

Mud flap assemblies including a frame, a securing assembly and mud flap panels; the securing assembly enabling the frame to be secured to a hitch assembly having a shaft, for further attachment to a hitch receiver secured to a vehicle; the frame having a rear plate that preferably includes a hitch opening for receiving the shaft of the hitch assembly. The frame is preferably configured to engage or rest upon a portion of a bumper of the vehicle to minimize vibration of the frame during use. The mud flap assembly preferably includes a pair of stops that are preferably adjustable and are constructed and arranged to engage or rest against the bumper. The mud flap assembly preferably includes enlarged mud flap panels and mud flap support members for additional support of the enlarged mud flap panels. Methods of installing mud flap assemblies are also disclosed.

Disclosed is a wheelhouse structure of a vehicle, including an inner panel with an inner flange that includes a straight portion, and an outer panel with an outer flange sized and shaped to interface with the inner flange along at least the straight portion. The outer panel includes a stiffening bead situated forward from, or proximate to a forward portion of, the straight portion. The wheelhouse structure also includes a plurality of joins coupling the inner flange to the outer flange, and a gap in the plurality of joins that is aligned with the first stiffening bead. When a rear portion of the wheelhouse structure is subjected to a loading force in a forward direction, the outer panel bends in locations proximate to the stiffening bead more easily than in locations remote from the stiffening bead.
