Fender Design

DESIGN OF CAR FENDER

Fender: Fender is the part of an automobile or other vehicle body that frames a wheel well Its primary purpose is to prevent sand, mud, rocks, liquids, from being thrown into the air and on to the engine compartment by the wheel when the vehicle is in motion.

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.

Design considerations: while designing the fender mostly the mounting areas will be taken into consideration

1.Drip area

2.sill mounting

3.Bumper mounting

4.A pillar mounting

• Also, it is made sure that all the bolts are invisible and are internal only so that it doesn't affect the styling and looks of the car
• Embosses are provided in order to add strength and provide convenience during the bolting process.

DRIP AREA: the drip area is the part of a fender which is bolted on to the engine compartment. while designing the drip area the guidelines in the below image are followed

it should be designed in such a way that a gap of 150 mm from headlight end .and 200 mm from a pillar end should be there.

beads are provided in order to preserve the structural integrity during bolting and also to add strength to the drip mount

BUMPER MOUNTING: This is the region where the fender will be mounted on to the bumper with the help of bolts .the inputs for this are taken from the design team working on the bumper.

A-PILLAR MOUNTING: this is for attaching the fender to the a-pillar area

.

SILL MOUNTING: sill mount is for attaching the fender to the sill area which is basically the bottom portion of the car near the front door

SPLASH COVER MOUNTINGS: used for mounting the splash guard on to the fender
