Wings-vehicle bady part

 Wings
A wing is a part of the body which covers the wheel. Apart from covering the suspension construction, the wing prevents water and mud from being thrown up on to the body by the wheels. The front wings (or the fender assembly) are usually attached to the wing valance of the front end assembly (see Figure 1.45) by means of a flange the length of the wing, which is turned inwards from the outer surface and secured by either welding or bolts. Adjustment for the front wing is usually provided for by slotting the bolt holesso that the wing can be moved either forwards or backwards by loosening the attaching bolts. This adjustment cannot be made if the wing is welded to the main body structure.
In some models the headlights and sidelights are recessed into the front wing and fastened in place by flanges and reinforcement rims on the wing. Any trim or chrome which appears on the side of the wing is usually held in place by special clips or fasteners which allows easy removal of the trim.
The unsupported edges of the wing are swaged edges known as beads. The bead is merely a flange which is turned inwards on some cars and then up to form a U-section with a rounded bottom. It not only gives strength but prevents cracks developing in the edges of the wing due to vibration, and it provides a smooth finished appearance to the edge of the wing.
In general the rear wing is an integral part of the body side frame assembly and rear quarter panel.
When the wing forms an integral part of the quarter panel, the inner construction is used to form part of the housing around the wheel arch. The wheel arch is welded to the rear floor section and is totally concealed by the rear quarter panel, while the outer side of the wheel arch is usually attached to the quarter panel around the wheel opening.
This assembly prevents road dirt being thrown upwards between the outer panel and inner panel construction.
