ABSTRACT:
The carriage comprises a frame (10) with two end axles (10A, 10B), between which is located a bissel truck (10C, 16), the chassis (16) of which is articulated on one of these end axles (10A), and a guide bar (18) articulated between the axle (10C) of the bissel truck and the other end axle (10B). At least one wheel (C) of the bissel truck functions as a rail tracer. Grinding heads (T1, T2; T5, T6) are articulated on this chassis (16) and on this guide bar (18) by means of connecting rods (S1, S2; S5, S6) and are thus guided independently of the positions of the end axles, in such a way that the contact point of each grinding wheel (M1, M2; M5, M6) follows the rails independently of curves, thus compensating the cambers at these points. The carriage can have several successive bissel trucks articulated on one another, each guiding grinding heads, or a system of levers for the indirect guidance of the grinding heads, this system being controlled by a bissel measuring truck. To compensate the variation of the rails, telescopic bissel trucks can be provided.
