Innovation on Central Wheel Nut to Racing Prototype Vehicle 2013-36-0472
The main characteristics required when fastening racing cars wheel are the resistance to self-loosening plus high-speed to assembling and disassembling of the wheel. To attend these two contradictory characteristics, it is necessary to develop differentiated fastening solutions.
This work presents a new concept of fastening central wheel nuts for racing cars with improved fastening efficiency regard safety and assembly speed in comparison to the current fastening. The new wheel nut was designed and validated through analytical and FEM analysis as well as real tests.
