Fender Design - Wheel Arch Challenge

PPushpak Patil28 May 2023

Fender (Wheel arch):-

The wheel arch is a crucial component of the fender that encompasses the upper section of the wheel in a vehicle. Its design serves multiple purposes, primarily focusing on shielding the wheels and providing protection to both the passengers inside the vehicle and pedestrians outside. The wheel arch aims to prevent water, mud, stones, and other debris from being projected into the air by the rotating tires.

The wheel arch area of the fender typically takes the form of a cover or shield that surrounds the perimeter of the tire. Its purpose is to hinder any debris, such as dirt, sand, snow, etc., from entering the vehicle or the body-in-white (BIW) area. Additionally, it prevents these materials from being thrown outside the vehicle, potentially causing damage to other vehicles or posing a risk to pedestrians on the road.

To ensure compliance with regulations and standards set by different countries, vehicles must meet specific criteria for the design and functionality of the wheel arch. These standards are established to promote safety, minimize the risk of accidents, and maintain cleanliness on the roads.

Overall, the wheel arch is a vital component of the fender, contributing to the protection of both the vehicle and its surroundings, and adherence to country-specific regulations is crucial for vehicle approval and operation.

European Standards:-

European regulations stipulate specific requirements for the wheel arch design in relation to the tire clearance. These regulations mandate a predetermined clearance or minimum distance of 10mm that must be maintained between the fender and the corresponding tire at certain points along the tire profile. This clearance is crucial to ensure proper functionality and compliance with safety standards.

Given Data Calculation:-

Here a design of fender along with tyre is provided and i have applied sketches and points to determine wheel arc gap along the fender is valid or not

so for doing this firstly i have created a datum at center of the tire, and created a sketch along that first i have created 2 line one is horizontal and another is vertical and along the vertical line i gave created two lines 1st will be deviated along 30 degrees along -xy plane and another will be deviating along 50 degrees along xy plane, then by using 2D projected curve i projected the fender along the lines which i have created. and made points along the intersections.

Sketch will be as shown:-

Calculations:-

Using measure tools we can measure the distance between the points.

Here We can Directly see that the measures varies along the curve so we can clearly say that we should have to change the design of the fender by contacting the styling Colleagues.

This Design Fails.
