Fender Design

AIM:

Follow the given Master section to create the Drip Area . For the Sill, Bumper, Baffle(Splash), and A-Pillar mount create your own design according to the Engineering standard that you learned.

Fender:

• Fender is one of the important outer body part of an automobile vehicle whose function is to cover or shield the wheel above the ground.
• It's primary function is to prevent mud, small rocks, sand, liquid and other small elements present on the road being thrown in the air by the rotating motion of the tyre.
• When the vehicle is in motion, the tyre pick ups the small elements (solid & liquid) present on the road and due to the centrifugal action these elements got thrown outside as well as inside the car and engine compartment. This activity might cause some hazards to the pedestrians, to the vehicle itself and other vehicles around. The fender eleminates this activity in considerable amount and these striking particles by the tyre gets accumulate on the baffle mounted underneath the fender.
• The fendre also act as a cosmatic part which hides the BIW components present inside and the ugly regions of the vehicle.

Types of Fenders :

1. Full bumper type

• 
• The full bumper type fender covers the area all the way from head lamps till the A-piller of the car.
• The full body type fenders were use in some old cars before but as the time has pass, engineers realised this type of fender cause more scrap, large blank size and hence cause more manufacturing cost. Therefore this fashion of fender has got stop due to these reasons.

2. Half bumper type

• 
• In half bumper type fender, the frontal portion is reduced till which the head lamp ends. This cause considerable amount scrap reduction and blank size as well. Also if the blank size will be increase little bit so that it could accomodate the other side fender, the process could monufactured both the fenders at the same time.
• Therefore the manufacturing process becomes more cost effective and time saving in case of the half bumper type fender.

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 Features of Fender:

Mounting Area

1. Bumper
2. Drip
3. A Pillar
4. Sill
5. Baffel

Bumper

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

Drip

• It is the important mounting uni of the fender . it is connected with the engine compartment, therefore a 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 the cowl top
• For placing the headlamp we have to leave at least 150 mm at the front while designing the fender
• The cowl top part consists of a wiper motor and its instruments

Sill

The 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.

BAFFLE MOUNTINGS

Baffle mounting or mudguard are clip-fit types 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.

A-PILLER AREA

The A-pillar is the structural pillar that combines the body with the roof . this makes the sides of

the windshield rest . front fenders are fastened to the A-pillar to form a robust structure.
