Fender Design

AIM:

The aim of these project is to design fender and the main design requirements for Drip area, Bumper, A pillar and Sill mounting areas.

Outer of car :

Fender :

Fender is a front outer side member of a car which covers the wheel side. Fender purpose is to prevent sand, mud, rocks, liquids and other particles.

Fender is a closure component, closing the engine compartment and other compartments. The major role of the fender is to avoid the chipping inside the engine compartment. During the motion the wheel picks a sand mud and small stone particles and throws it inside the car and these fenders will be helpful in preventing them by hitting inside the engine compartment and car body. These fenders will have a plastic part which lies on wheel arch area. The fender plays a major role to avoid problems for pedestrian also.Fender are typically rigid and can be damaged by contact with the road surface. It is often also called as Mudguard.

Types of fender :

• Full Bumper Type.
• Half Bumper Type.

Full Bumper type :

It is not used now a days because they requires bigger size blank to produce the part and the large scrap is also produced.

Half Bumper Type :

Half bumper types are used in present and future also because the blank size is less and the wastage or scrap is less comparing to full bumper type fenders.

Uses of car Fenders :

• Car Fender limit the exposure of your car's body and engine to external elements that are harmful.
• Fender flares are attached to ensure that both the body and engine have minimal contact with corrosive elements
• Car Fenders provides safety to the driver and the passengers at the time of accidents or collisions. They are manufactured in a way to provide bend during front and side collisions.
• Car Fenders are designed to avoid wind resistance and make your car more aerodynamic.
• Car Fender enhance the overall look of your cars. Fender flares are available in distinctive designs in the market. Mostly you find universal Fender flares, but you can get customized cars Fenders to fit your car wheels.

DESIGN CONSIDERATIONS

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

1. Drip Area Mounting.
2. A-Pillar Mounting.
3. Sill Mounting.
4. Bumper Mounting.
5. Baffle Mounting.

For the creation of the Drip Area Mounting, the given Master Section is followed, and the other mounting points are created by assuming appropriate positions with the respected components.

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: Sill mounting is created on the bottom portion of the fender for attaching to the sill.

4. Bumper Mounting: This mounting point is created for attaching the bumper to the fender. It should have enough strength to hold the bumper steadily.

5. Baffle Mounting: These mounting points are created for attaching plastic components i.e baffle which prevents chipping inside the engine compartment.

DIFFERENT VIEWS

CONCLUSION:

Here, developed mounting flanges in Drip area, Sill mount, A pillar and Bumber with given design requirements.
