Abstract
An idler wheel axle for single-axle or double-axle chassis of rail vehicles having individually mounted wheels and U-shaped, dropped-framed vehicles with lateral carrying legs, wherein each wheel is rotatably mounted on the inside of the associated carrying leg, and on an axle stub of the carrying leg via a wheel mounting, and wherein each wheel is torsionally connected on an inside thereof to a shaft that extends outward through orifices within the wheel and the carrying leg.
Claims18
An idler wheel axle with individually mounted wheels for chassis of rail vehicles, with a wheel carrying frame externally surrounding the wheels with lateral carrying legs, each wheel being rotatably mounted on the inside of the associated carrying leg, each wheel mounted on an axle stub of the carrying leg by a wheel mounting, and each wheel being torsionally connected on an inside of the wheel to a shaft which extends outward through orifices of the wheel and of the carrying leg, the wheel mounting consisting of two part bearings, and the first part bearing being arranged within the orifice of the wheel between the wheel and the axle stub of the carrying leg, while the second part bearing is arranged, offset axially and radially to the first, within the orifice of the carrying leg between the carrying leg and the shaft.
An idler wheel axle assembly, comprising:
- a plurality of wheels;
- a wheel carrying frame having a plurality of wheel carrying legs, wherein the wheels are rotatably mounted to an inside of the wheel carrying legs such that the frame externally surrounds the wheels;
- an axle stub operably connected to each of the wheel carrying legs of the frame by a wheel mounting;
- and
- a shaft torsionally connected to an inside of each wheel, the shaft extending outwardly through orifices of each wheel and orifices of each carrying leg;
- wherein the wheel mounting includes a first part bearing and a second part bearing, the first part bearing arranged within the orifice of the wheel between the wheel and the axle stub, the second part bearing arranged within the orifice of the carrying leg between the carrying leg and the shaft, and offset axially and radially to the first part bearing, the first part bearing including an outer ring rotatable with respect to the axle stub and an inner ring seat non-rotatably with the axle stub, and wherein the second part bearing includes an inner ring rotatable with respect to the carrying leg and an outer ring seated non-rotatably in the orifice of the carrying leg.
