Back to the future for spoked wheels

The main cost driver is the mass of the wheels, which must be accelerated when starting and decelerated when braking. Since the mass of the wheel is unsprung, the forces acting between the wheel and rail are particularly dependent on the mass of the wheel. [...]the space is used optimally in terms o...

Description
Summary:The main cost driver is the mass of the wheels, which must be accelerated when starting and decelerated when braking. Since the mass of the wheel is unsprung, the forces acting between the wheel and rail are particularly dependent on the mass of the wheel. [...]the space is used optimally in terms of design strength. [...]the spoked wheel design, which has been developed as part of Shift2Raiľs TD1.4 Running Gear Demonstrator project, addresses all three objectives of reducing mass, wear and sound radiation.
