Abstract
This invention relates to an underfloor wheel set lathe for the profiling of wheel sets of trackbound vehicles of the type in which the wheels are at least in part supposed by rolls carried by a roll carrier, at least one of the rolls being driven. Movement of the roll carrier is resisted by a horizontally acting brake mechanism which permits vertical lifting movements of the carrier. The force with which horizontal movement is resisted may, by suitable hydraulic means, be controlled as a function of the cutting force or driving force imparted to the wheels, the lifting force exerted against the wheels, or otherwise coordinated with the force applied in the course of profiling.
Claims7
In an underfloor wheelset turning machine for the profiling of wheelsets of vehicles which run on rails roll carrier means mounted for horizontal and vertical movement, a spaced pair of rollers mounted on said carrier means, said rollers being positioned to contact at least the tread of a wheel of a wheelset disposed in said machine, and at least partially supporting the weight thereof, drive means connected to at least one said roller for driving said wheel, the improvement which comprises horizontally acting brake means operatively connected to said carrier means for yieldably resisting horizontal movement of said carrier means in a plane perpendicular to the axis of said wheel.
An underfloor wheel set turning machine for the profiling of wheel sets of vehicles which run on rails comprising roll carrier means mounted for horizontal and vertical movement, said roll carrier means including oppositely directed vertical guide surfaces, a spaced pair of rollers mounted on said carrier means, said rollers being positioned to contact at least the tread of a wheel set disposed in said machine, and at least partially supporting the weight thereof, drive means connected to at least one said roller for driving said wheel, and horizontally acting brake means operatively connected to said carrier means for resisting horizontal movement of said carrier means in a plane perpendicular to the axis of said wheel, said brake means comprising horizontally aligned first and second brake assemblies, each said assembly including a guide roll rotatable about a horizontal axis and engaging one of said guide surfaces.
