Fender Design

FENDER DESIGN

     OBJECTIVE

To design a  front fender of a car by following the given master section as per the design considerations of OEM.

     FENDER

It is an aesthetic component/part of a car that frames the wheels. Prevention of sand,  mud particles, and other road contaminants from being thrown into the engine compartment and also to the pedestrians by the rotating tires are the main purpose served by the fenders.The front fenders are separate components whereas the rear fenders are integrated with the body sides.

TYPE OF FENDER

• 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:

These fenders are mainly used for serving the purpose of cost-cutting and reducing enough proportions of the steel wait resulting in a reduction of the weight of the vehicle slightly. They can be economically manufactured, i.e by slightly increasing the blank size, we can produce two fenders at a time.

 USE OF FENDER

Its primary purpose is to prevent sand,mud,rock,liquid,and other road spray from being thrown into the air by the rotating tire.Fender are typically rigid and can be damaged by contact with the road surface.

FENDER MOUNTING

     The front fender has basically five mounting positions with respect to the other components. The mounting positions are as follows.

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 region is located near the cowl of the vehicle where the fender is fastened with the bottom edge of the windshield. This mounting is covered with the side rear-view mirror .

    

3.SILL MOUNTING

•     The area at which the bottom of the fender gets connected to the floor near the bottom edge of the door. The Embossed sill mounting of the fender is attached with the fasteners.

4.BUMPER MOUNTING

• The bumper mounting region is located beneath the bumper. The fender gets attached before the installation of the bumper. After fixing the fender with fasteners the bumper will cover the bumper mounting.

5.BAFFLE MOUNTING

• In this region, the baffle gets installed to the fender with the help of clips which holds the baffle with the fender along the wheel arch.

CONCLUTION

    The front fender is designed according to the given master section and CLASS A Surface as per the OEM Standards .
