Fender Design

AIM

To design a front fender of the car with all the provisions which include so many mountings such as (sill mounting,drip mounting,bumper mounting,baffle mounting,a-pillar mounting)

FENDER

Fender is the part of an automobile (vehicle body) that frames a wheel well(the fender underside).the wheel arch is placed on the fender above the wheel,its primary purpose is to avoid the sand,mud and other road particles from being thrown into the air by the tire rotation.It prevents the car engine compartment,some part of under body,pedestrian from those road particles.This can increase the pedestrian safety,life time of car under body.

For vehicles with narrow car body that exposes the tire ,the fender is an exposed curve over the top of the tire.Fior wide body vehicles that cover the tire ,the fender forms the wheel well surrounding the tire.

TYPES OF BUMPER

Full Bumper Type

These types of fenders were used in earlier models of vehicles. They contribute to the major increment of the steel weight by just covering the front headlights with respect to the bumper region. The problem associated with this kind of fender is there is a lot of wastage in the blank and every inch of a material is a cost to the industry.

Half Bumper type

This type of fender is mainly used for cost reduction and weight reduction,this also helps in reducing the weight of a car thereby increase the vehicle performance.we will slightly increase the blank size compared to the full bumper type,it will gives us two half bumper type fender instead of one full bumper type fender.

IMPORTANT MOUNTING IN FENDER

Drip mounting

A pillar mounting

sill mounting

cowl mounting

Body mounting.

1. Drip Area Mounting:

• The drip area is the most important mounting in a fender, it is the point where the fender has to be attached to the engine compartment.
• The drip area should be designed in such a way that it should be at least 150mm away from the front end of the fender to have sufficient space for mounting headlamps housing.
• Mostly the drip area starts from 200mm away from the rear end of the fender, to have sufficient space for the cowl which carries the wiper equipment.
• The length of the drip area depends on the length of the fender.

2. A-Pillar Mounting:

• This mounting position is created for attaching the fender to A Pillar of the vehicle.
• The mounting has to be created by taking the reference from the A-pillar of the vehicle.
• Enough clearance should be given for the easy mounting of the wiper equipment

3. Sill Mounting

4. Bumper Mounting

5. Baffle Mounting

It i sused to mount the wheel arch through fastners or by reviting

CONCLUSION

The fender is designed according to the master section to the given skin data.
