- What is Fender : Fender is a part which covers a wheel.
To prevent water and mud spray, and also for aerodynamic purposes. When the vehicle is moving tyre picks up stones & others and hurl them in all direction thus in order to prevent pedestrians from these stones fenders are used.
- What is Wheel arch/wheel well:
The wheel arc is an integrated part of a fender assembly. It is a semi-circular part which is positioned above the wheel of a vehicle.
1. Wheel Arch:
- Wheel Arch is the semi-circular part of the fender positioned above the wheel of the vehicle.
- The design of Wheel arch of a fender should be such that it must shield wheels and protect both passengers’ compartment and pedestrians from projection of water, mud and stones.
- For the vehicle to has its use permit in different countries, the wheel arch of fenders must be compliant with the standards and regulations set by the respective countries.
2. Objective of the Wheel Arch Challenge:
The objective of the wheel arch challenge is to calculate the wheel arch area and to prove whether the given fender of car will pass the European standards or not.
- FENDER REGULATIONS
- European Regulation:According to European regulation, the clearance value between fender and tyre profile must be greater than 10mm. The value is measured in projected point at an angle 30° forward and 50° rearward respectively. The measurement took in five different positions of the tyre at point a & b the clearance is acceptable. But at point c, d & e there is a negative sign which denoted the interference of wheel arch with a tyre.
- US Regulation:According to per US regulation, the clearance between tyre and fender must be greater than 5mm. The projected points to be measured are at an angle 0° forward to 100° respectively. Thus each position is divided into 10°. Thus the projected distances are measured at around 21 different points.
- Japanese Regulation:According to Japanese regulation, the clearance between tyre and fender must be greater than 5mm The projected points to be measured are at an angle 30° forward & 50° rearward respectively.
