Fender Design
INTRODUCTION
Fender is the American English term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well (the fender underside). Its primary purpose is to prevent sand, mud, rocks, liquids, and other road spray from being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with the road surface and they are basically present to prevent any injuries to pedestrians and contains the motion of these particles.
TYPES OF FENDERS
Two types of fenders available in market there are full bumper type and half bumper type now presently we use half bumper type because full bumper type is really big and quite lot of wastage, so we use half bumper type to reduce the wastage and weight reduction also.
FULL BUMPER TYPE
This fender variant extends from the front bumper to the rear, delivering comprehensive coverage and a robust protective shield.
HALF BUMPER TYPE
Designed for sportier or stylized vehicles, this fender type strategically covers a portion of the wheel well, adding a touch of flair to the design.
MOUNTING
- Bumper
- Drip
- A Pillar
- Sill
- Baffle mounting
BUMPER MOUNTING AREA
This is designed by consulting the bumper design team to design the bumper and fender assembly fixation.
SILL MOUNTING AREA
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 MOUNTING AREA
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 PILLAR MOUNTING 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.
DRIP MOUNTING AREA
Drip area mounting is the important part in the fender. This mounting is attached to the engine compartment of the car. Fender drip area is mounted via weld nuts to the engine compartment. The height of drip area mounting should be less than 40mm so that it reduces the spring back effect during manufacturing and reduce NVH issues during vehicle movement. Mounting screw holes of diameter 5mm are and locator pin holes are created for mounting guidance. It should be distanced at least 150mm from the front side and 200m from the rear side. Ribs are to be provided in order to increase the strength of the mounting part. Embosses are created as per design standards for proper fixation.
