Fender Design

DESIGN OF CAR FENDER

Fender is  the part of an automobile, motor cycle or other vehicle body that frames a wheel well (the fender underside). Its primary purpose is to prevent sand, mud, rocks, liquids, and other road spray from being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with the road surface. 

Sticky materials, such as mud, may adhere to the smooth outer tire surface, while smooth loose objects, such as stones, can become temporarily embedded in the tread grooves as the tire rolls over the ground. These materials can be ejected from the surface of the tire at high velocity as the tire imparts kinetic energy to the attached objects. For a vehicle moving forward, the top of the tire is rotating upward and forward, and can throw objects into the air at other vehicles or pedestrians in front of the vehicle.

There are generally 5 mountings on a Front fender-

1. Body

2. A-Pillar

3. Sill

4. Cowl

5. Drip

DRIP MOUNTING:

• It is the area through which the fender is attached to engine housing through fasteners.
• There should be some consideration followed to design the drip area of the fender.
• From the backside of the front fender, there will be 200mm clearance for the cowl(wiper motor) mounting area.
• From the front side of the front fender, there will be 150mm clearance for the headlamp housing unit.
• The remaining area we can use to design a drip area.
