Abstract (en)
A current return assembly (15,29) for railway traction and brushes therefor, wherein the brushes comprise a conductive body of metalgraphite (1,40) and a small plate of a lightweight material (2,46) coupled to the conductive body by means of a centering wedge (5,47), the resultant brushes having reduced weight and being adapted for reliable utilization at an optimum contact pressure and with a consequently increased service life even under severe conditions of operation and acceleration stresses on the order of 20 g. The reduction in weight of the brushes and consequent reduction in the mechanical stresses caused thereby, enable the assembly (15,29) to be made of light alloy. <IMAGE>
