Abstract
A wheel for rail vehicles with at least one disc which is connected to an axle, and with a wheel rim having a tread or surface surrounding the disc, while the rail tread in engagement with the rim tread results in contacting points of the wheel during straight forward drive of the vehicle located on the tread or track of the rails. At least within that region of the rim which contains the above mentioned rail contacting points of the wheel rim the wheel rim is turnably connected to the disc for turning about an imaginary axis located in about the driving direction of the wheel.
Claims13
A wheel arranged for movement substantially longitudinally along a rail and having a rotational axis therewith which includes in combination:
- at least one disc of said wheel rotatable about said axis, and a wheel rim having a tread surrounding said disc, said disc having said wheel rim universally mounted therewith, said tread having contacting points for engaging the rail, said rim at least within the region of said contacting points being journalled rotatably relative to said disc about the axis located at least substantially in the direction of movement of said wheel, and means effecting lubrication between said rim and said disc to supplement dampening for rolling and irregular oscillating motion during universal movement both transversely and longitudinally therewith.
