Fender Design

Aim:

To create a standard fender design with the parts of Drip, Sill, Bumper, A piller, Baffle areas.

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.

Types of Bumper:

1. 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.

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 of fender:

There are 5 mounting regions on the fender , they are

• Drip mounting,
• Sill mounting,
• Bumper mounting,
• A piller mounting,
• Baffle mounting.

Design of Drip area mounting:

It is the important mounting uni of the fender . it is connected with the engine compartment , therefore the lot of design constraints are to be followed while designing the fender.

While designing the drip area we have to initially leave 200-300 mm for cowl top.

For placing the headlamp we have to leave at least 150 mm at the front while designing the fender.

Cowl top part consists pf wiper motor and its instruments.

Two darts are added on the longer side of the drip area in order to provide the stiffness and adds strength to the part . This helps the fender to not to vibrate and impact the forces outside of the fender during motion of the vehicle.

Embossing are provided on the mounting to strengthen them during fastening.

Design of Sill area mounting:

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 . M5 fasteners are used to fix the fenders on the sill body.

Design of Bumper area mounting:

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

Design of A Piller area mounting:

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 area mounting:

Baffle mounting or mudguard are clip fit type of mounting on the inner side of the fender arch over the Tyre . it protects the car 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 .

Final Design of Fender:

Conclusion:

The complete standard fender design was created by using master section with the all parts.
