CAR MOUNTED AXLE WITH RESILIENT FRICTION LINKAGE BETWEEN WHEELS Russian patent published in 2014 - IPC B60B37/00 

FIELD: transport.

SUBSTANCE: invention relates to railway car running gear. Proposed mounted axle comprises differential axle, bearing assembly and two half-axles fitted one into another. Inner bearing assembly incorporates jointing barrel to be fitted on thrust and radial bearings intended for precise location of bearing outer races. Required radius of transition is set in half-axle, at transition from solid cross-section to cavity between bottom surface and cavity inner cylindrical surface to rule out concentration of stress at said transition. Solid cross-section half-axle is made integral with thrust collar, ledges and two journals to locate radial and thrust friction bearings.

EFFECT: required relationship between angular velocities of the wheel, higher reliability and safety.
