| 摘要 |
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. |
