Spoke butted (double or even triple) to reduce weight while maintaining strength. A variation on the wire-spoked wheel was Tioga's "Tension Disk", which appeared superficially to be a solid disk but was in fact constructed using the same principles as a normal tension-spoked wheel. Instead of individual wire spokes, a continuous thread of Kevlar (aramid) was used to lace the hub to the rim under high tension. The threads were encased in a translucent disk for protection and some aerodynamic benefit, but this was not a structural component. Wire spokes can be radial to the hub but are more often mounted
Electrodynamic wheel track that can inductively create suspension and propulsion forces simultaneously. The parameters that affect the performance of this electrodynamic wheel are studied using a 2-D steady-state finite-element method. Electrodynamic wheel An electrodynamic wheel is a type of wheel proposed for use in electrodynamic levitation maglev. Unlike a conventional wheel, an electrodynamic wheel has a rim studded with magnets of alternating poles. As the wheel spins, which is done at a rate so that there is slip between the rim and the guideway's surface, magnetic fields are induced in the conductive guideway which repels the wheel. Depending on the spin, electrodynamic
