Fender Design - Wheel Arch Challenge
Fender Wheel arc area:- The gap between wheel and wheel arc of fendar is important criteria of the fender design becouse It save engine part & also ppredestian from mud, stone coming from wheel.
Difrent contries varies gap according to our regulation requirement. For example japan requirement 5mm min. gap between fender wheel arc & wheel.
Europian regulation requirement:- According to design of fender, wheel arc is completely inside the fender and minimum distance between fender & wheel arc is 10mm in all section.
Procedure:-
- In Wheel arc creat two referance line horizontal & vartical which is passes centre of wheel arc.
- Creat section at angle 30 degree forword from vartical referance line. and project it to top view make section A-A'.
- Creat section at angle 50 degree rearword from vartical referance line. and project it to top view make section B-B'.
- Creat section at vartical diastance 150mm from horizontal referance line. and project it to top view make section C-C'.
- Creat section D-D' which is between equall anguler distance section B & section C and project it to top view.
We have find at all five section A-A', Vartical section, section B-B', section C-C' & section D-D'
RESULT :- According to Europian regulation requirement calculate distance between wheel arc & fender
Result in tabuler form
| Sr.No. | SECTION | Distace b/w wheel arc & fender |
| 01 | A-A' | 10 mm |
| 02 | Vartical | 9.949 mm |
| 03 | B-B' | -0.1126 mm |
| 04 | C-C' | -1.798 mm |
| 05 | D-D' | -3.60 mm |
CONCLUSION:-
- Section A-A' are qualified minimum require distance 10mm.
- Varticle section distance is postive but value 9.945 mm which is less than minimum requirement
- Section B-B', C-C' & D-D' distance is negative means fender is inside of wheel arc or inside the wheel arc.
- This fender does not protect engine part and predestian from mud, stone comming from centrifugal action during running wheel
- this fender designe completely wrong design
