FIELD: transportation. ^ SUBSTANCE: current collecting element of electrically propelled vehicle is in form of plates with base, lateral surfaces and contact surface with lead in and matching sections which are symmetrical on its edges. The lateral and contact surfaces are arched and have a profile, the cross section of which is bounded by a curve which is defined by the expression where B is the width of the plates in mm, H is the height of the plates in mm, h is the distance from the base of the plates to any point on the curve with values of b n is a coefficient, determining the degree of curvature of the profile of the arched surface of the plates. ^ EFFECT: lower wear-out rate of current collecting element and more reliable current collection. ^ 3 dwg |
