  • a grinding machine of this type is known from patent DE-C-28 43 649 of the applicant, allowing the elimination of corrugations and the reprofiling of the rails, and also from the European patent application EP-A-87116468.7 of the applicant allowing the reprofiling of the rail mushrooms, this machine being equipped with at least one grinding head per row of rails which is displaceable in height by at least one lifting device.
  • FIGS 1 to 3 illustrate, by way of example, the known state of the art.
  • Figure 1 a grinding machine known from European patent application EP-A-87116468.7 mentioned above formed of a grinding car 1 with two axles 2, movable on track R and provided with a grinding carriage 3 equipped with grinding heads T with grinding wheels M.
  • This grinding carriage 3 is suspended by jacks 4 from the chassis of car 1, so as to be movable relative to car 1, to be able to fit into the curves and to be lifted when walking high.
  • FIG. 2 is a schematic view from above of the lower part of the carriage 3 on a larger scale, it is supported by two axles 10A, 10B, provided with wheels A, A ′, respectively B, B ′ and connected by a frame 10 and comprises on each row of rails R1, R2 four heads grinding T each supporting a peripheral grinding wheel M1, M2, M3, M4, respectively M5, M6, M7, M8.
  • Each grinding head T is suspended in an articulated manner in the chassis 10 around a horizontal axis 7 and a vertical axis 8; around the horizontal axis 7 each head can be lifted, independently of the others, by a jack 5 diagrammatically indicated in FIG. 1 and the upper end of which is articulated to the chassis 10 of the carriage.
  • Each grinding head is further connected to the frame 10 of the carriage 3 by a connecting rod S which is articulated at 6 to the frame 10 and at 6 ′ to the frame of the grinding head T.
  • These connecting rods are adjustable to determined lengths, and guide the grindstones.
  • the two axles 10A, 10B of the carriage are supported, using hydraulic cylinders 9 supported by a stop of the chassis of the car 1, against the inside of one of the rows of rails, in this case the rail R1.
  • the adjustable suspension of the grinding heads can be that described in patent DE-C 28 43 649 of the applicant.
  • the grinding wheels are positioned on the straight line determined by the wheels A, B respectively A ′, B ′ of the carriage 3 located on the same side, and their point of contact with the rails is defined by the points C1 to C4 ( Figure 3) .

  • This displacement, or deflection is a function of the radius of curvature and the position of the grinding wheel relative to the ends of the arc between A and B.
  • the grinding wheels take the combined profile of rails, this profile changing according to the values of the arrow in the curves; therefore at each entry and exit of the curves the grinding wheels must change their profile, which causes in the transition zones a modification of the rail profile.
  • the present invention aims to provide a grinding machine for guiding the grinding wheels as a function of the curve of the track and, thereby, the compensation, at least approximate, of the arrows of the rail curve.
  • the machine according to the invention is characterized by the characteristic clause of claim 1.
