Published purpose
This project is the development of two systems that prevents Truck Wheels from escaping during operation thereby eliminating an oft times fatal hazard. The first invention uses a pre-calibrated wheel studs which are studs that have built in switches that activate at a predetermined stud elongation and causes a signal to be sent to the vehicle operator that a specific Lug Stud is either under torqued, over-torqued or sheared. The second invention is a compression ring that uses low Young's modulus material below the lug nut to compress and close a switch at a predetermined pre-load and cause a signal to be sent when an undesirable torque level is present.
