Fender Design

Objective

To design the mounts of the fender

Fender design

Primary purpose of the fender is to avoid mud, rocks and other particles thrown in to air due to the rotation of the wheel.
Fender prevents the pedestrians as well as engine components from those particles.
Front fenders are usually designed individually where as rare fender is accommodated in body side structure.

Types of Fender

Fig Types of fender

Now a days the full bumper type is not using in order to reduce the material as it requires bigger blank size and also there is a lot of scrap in full bumper.
Whereas for the half bumper we can reduce a lot of scrap and we can prepare to fender from one blank just by increasing small amount of blank size.
Also in the half bumper plastics are used to reduce the weight of the component.

Fender have 5 main mount attachments

Design considerations for the fender design for drip area

First and main consideration was 150mm gap from the front end of the drip to bumper for headlamps
200mm from the rear end is kept for the wiper motor assembly. I should not be more than 300mm.
As the engine components should not be visible outside initially 3⁰ angle and 9mm length is given.
The depth should be in the range of 40 to 60mm, if the depth increases further the spring back effect will also increases.
Embosses are given to increase the strength.
