Method and device for the machining of the wheel running surface of wheels for rail vehicles
11872640 · 2024-01-16 · ·

A device for machining wheel running surfaces of a wheel for a rail vehicle includes a wheel machining machine having a machining tool for performing a re-profiling process on the wheel and a rolling tool for performing a rolling process on the wheel and applying a rolling force to the wheel. A clamping unit is alternatively used as a receptacle for the machining tool or for the rolling tool. A first drive motor drives a first feed axle to translate the clamping unit along a first axis. A second drive motor drives a second feed axle to translate the clamping unit along a second axis perpendicular to the first axis. A control module adjusts the rolling force by controlling torques of the first and second drive motors.

RAIL MILLING VEHICLE
20200063377 · 2020-02-27 ·

The present disclosure relates to a rail vehicle that includes a chassis and a rail milling assembly coupled to the chassis. The rail milling assembly includes a bracket for coupling the rail milling assembly to the chassis and a milling workhead forming a portion of the rail milling assembly. The milling workhead including a spindle and a cutter depending downwardly from the spindle. The spindle and cutter are driven by a spindle motor. The milling workhead further includes a cylinder rod disposed between the spindle motor and the spindle to thereby bias the cutter towards the rail during operation.
