Abstract
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.
Claims19
A rail vehicle, comprising:
- a chassis;
- and
- a rail milling assembly movably coupled to the chassis, the rail milling assembly including:
- a bracket fixed to the chassis;
- a milling workhead coupled to the bracket such that the milling workhead floats relative to the chassis in a lateral direction and in a vertical direction;
- and
- wherein the milling workhead including a cutter configured to remove material from a rail during operation.
A rail milling assembly configured to be coupled to a chassis of a rail vehicle, the rail milling assembly comprising:
- a bracket for coupling the rail milling assembly to a chassis of a rail vehicle such that the rail milling assembly floats relative to the chassis in a lateral direction and in a vertical direction;
- and
- one or more milling workheads each including a spindle and a cutter depending downwardly from the spindle, the cutter configured to remove material from a rail during operation;
- and
- a frame member configured to support the one or more milling workheads, the frame member movably coupled to the bracket;
- wherein the frame member defines at least one slot extending in a lateral direction, each slot being configured to receive a vertically extending pin of the bracket such that the pin is independently movable in both a lateral direction and vertical direction relative to the frame member.
