Device and Method for Simultaneously Machining Several Wheelsets of a Rail Vehicle

A device for machining, in particular for simultaneously machining multiple wheelsets of a rail vehicle, comprising:

• a first underfloor wheelset lathe for reprofiling wheels and brake discs from a first wheelset of a rail vehicle,
• a second underfloor wheelset lathe for reprofiling wheels and brake discs from a second wheelset of a rail vehicle,
• a third underfloor wheelset lathe for reprofiling wheels and brake discs from a third wheelset of a rail vehicle, and
• a fourth underfloor wheelset lathe for reprofiling wheels and brake discs from a fourth wheelset of a rail vehicle,
• wherein a second rail support is arranged between the third underfloor wheelset lathe and the fourth underfloor wheelset lathe,
• wherein the distance between the second underfloor wheelset lathe and the first underfloor wheelset lathe is adjustable,
• wherein the distance between the third underfloor wheelset lathe and the first underfloor wheelset lathe is adjustable, and/or
• wherein the distance between the fourth underfloor wheelset lathe and the first underfloor wheelset lathe is adjustable,
• characterised in that
• the second rail support is displaceable relative to the third underfloor wheelset lathe and/or relative to the fourth underfloor wheelset lathe.

A method for machining, in particular for simultaneously machining multiple wheelsets of a rail vehicle, comprising the following steps:

• a) Provision of:
• a first underfloor wheelset lathe for reprofiling wheels and brake discs from a first wheelset of a rail vehicle, and
• a second underfloor wheelset lathe for reprofiling wheels and brake discs from a second wheelset of a rail vehicle,
• b) Provision of at least two wheelsets to be machined of a rail vehicle,
• c) Adjusting the distance between the second underfloor wheelset lathe and the first underfloor wheelset lathe,
• d) Setting down and clamping of at least two wheelsets to be machined on the underfloor wheelset lathes assigned to them, and
• e) Machining at least two wheelsets to be machined of the rail vehicle on the underfloor wheelset lathes assigned to them, wherein
• a third underfloor wheelset lathe for reprofiling wheels and brake discs of a third wheelset of a rail vehicle and a fourth underfloor wheelset lathe for reprofiling wheels and brake discs of a fourth wheelset of a rail vehicle are additionally provided in step a),
• four wheelsets to be machined of a rail vehicle are provided in step b),
• in step c), the distance between the third underfloor wheelset lathe and the first underfloor wheelset lathe is adjusted and the distance between the fourth underfloor wheelset lathe and the first underfloor wheelset lathe is adjusted,
• in step d), four wheelsets to be machined are set down and clamped on the underfloor wheelset lathes assigned to them,
• in step e), the third wheelset and/or the fourth wheelset of the rail vehicle is additionally machined on the underfloor wheelset lathes associated therewith, and
• wherein in step a), a second rail support is provided between the third underfloor wheelset lathe and the fourth underfloor wheelset lathe,
• characterized in that
• the step c) comprises the following substeps:
• ca) determining the type of rail vehicle with the wheelsets to be machined, and
• cb) Setting stored, vehicle-specific distances between the second underfloor wheelset lathe and the first underfloor wheelset lathe,
• and that the second rail support is displaceable relative to the third underfloor wheelset lathe and/or relative to the fourth underfloor wheelset lathe.
