FENDER DESIGN

AIM: To design a front fender of a car

INTRODUCTION

Fender is the american english term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well. Its primary propose is to prevent sand, rocks, mud, liquids, and other road spray from being thrown into the air by the rotating tire.

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.

TYPES OF FENDERS

1. FULL BUMPER TYPE: These types of fenders were used in earlier models of vehicles.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

2. 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.

MOUNTING REGIONS ON FENDER :

• A- pillar mounting
• Body mounting
• Sill mounting
• Bumper mounting
• Drip mounting

Master Section:

DESIGN OF DRIP AREA MOUNTING :

• It is the important mounting unit of the fender . it is connected with the engine compartment , therefore the lot of design constraints are to be followed while designing the fender
• Embossing are provided on the mounting to strengthen them during fastening.

DESIGN OF SILL MOUNTING AREA :

Sill is the panel directly below the bottom of the door supporting the floor and may be used to combine the floor and the body.The bottom end of the fender is mounted on the sill body for reinforcement of the fender panel ,thus the sill mounting position is designed with holes and emboss.

DESIGN OF BUMPER MOUNTING AREA :

Bumper mounting area is used to fix the plastic bumper to the fender with the help of the fasteners

DESIGN OF A-PILLAR MOUNTING AREA :

The A -pillar is the structural pillar that combines the body to the roof . this make the sides of the windshield rest . Front fenders are fastened to the A-pillar to form a robust structure.

DESIGN OF BAFFLE MOUNTING AREA :

Baffle mounting or mudguard are clip fit type of mounting on the inner side of the fender arch over the Tyre.It protects the engine compartment and pedestrians from causing injuries from chip out debris on the road when the car is in motion.They are mounted on the fender using a special type of locking clips which are made up of plastics .
