Abstract
A frictional drive railway wheel truing system comprising a master lift and drive arm spaced from a slave lift and drive arm extending from within a railway pit for lifting a pair of opposed railway wheels off railway rails. Each master and slave drive assembly comprising frictional drums to turn a railway wheel from a wheel flange. A master and slave lathe assembly moveable along an axis parallel to a rotational axis of the frictional drums; each master and slave lathe assembly having a cutting bit positioned to engage a tread and a flange of a railway wheel in a cut mode at a location superior to the contact area of said frictional drums and railway wheel; and a hold down device fixing rotation of a railway wheel to a predetermined axis during a wheel truing operation.

A frictional drive railway wheel truing system comprising:
- a master lift and drive arm spaced from a slave lift and drive arm extending from within a railway pit for lifting a pair of opposed railway wheels off a pair of spaced railway rails;
- said master lift and drive arm and said slave lift and drive arm moveable between a lowered mode and a raised mode along a generally vertical axis;
- said master lift and drive arm comprising a master drive assembly at a superior end of said first master lift and drive arm;
- said slave lift and drive arm comprising a slave drive assembly at a superior end of said slave lift and drive arm;
- each of said master drive assembly and slave drive assembly comprising a pair of frictional drums spaced less than a diameter of a railway wheel for cupping a railway wheel there between;
- said pair of frictional drums driven by at least one drum drive motor for driving rotation of a railway wheel during a wheel truing operation;
- said frictional drums having a drive surface configured for engaging a railway wheel for lifting and driving the railway wheel in rotation;
- a master lathe assembly moveable along an axis generally parallel to a rotational axis of one of said pair of frictional drums;
- a slave lathe assembly moveable along an axis generally parallel to a rotational axis of one of said pair of frictional drums;
- each of said master and said slave lathe assemblies having a cutting bit positioned to engage a tread and a flange of a railway wheel;
- said cutting bit positioned in a cut mode to engage said tread and flange of a railway wheel at a location superior to the contact area of said frictional drums and railway wheel;
- and a hold down assembly configured for fixing rotation of a railway wheel to a predetermined axis during a wheel truing operation.
