FENDER DESIGN

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

FENDER: It is a plastic, metal, or rubber curved panel over the wheels on the side of a car, extending from the front bumper of the car to the door. The main purpose of fenders is to keep dirt, mud, and other debris off of the tires and braking system, making them safer and more efficient. The front fenders are separate components whereas the rear fenders are integrated with the body sides.

TYPES OF FENDERS:

• Full bumper type fender
• Half bumper type fender

Right now, the given fender is half bumper type fender.

The Standered clearence value of the fender above the tyre is 10 mm.

DESIGN CONSIDERATIONS:

For this front fender has basically have five mounting positions with respect to the other components.

• Drip Area Mounting.
• A-Pillar Mounting.
• Sill Mounting.
• Bumper Mounting.
• 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.
