CURRENT COLLECTOR OF ELECTRIC ROLLING STOCK Russian patent published in 2009 - IPC B60L5/00 

FIELD: transportation.

SUBSTANCE: current collector has current-collecting unit with sprung runner installed on semi-pantograph. Lower movable frame of semi-pantograph is hingedly connected with insulated base by torsion system of springing and hoisting mechanism. Upper movable frame with its lower end is hingedly connected to lower frame and via cable and lever to torsion. Upper movable frame with its upper end is connected hingedly by means of elastic joint to carriage of current-collecting unit. System of springing is arranged in the form of torsion installed parallel to axis of hinged joint of lower frame and connected with its single end to base, and with the other one via lever rigidly fixed on torsion to cable passing inside lower and upper frames via rollers installed in areas of frames joining, fixed to stem of current-collecting unit. Horizontality of working surface of current-collecting unit at all its heights is provided due to elastic rotation of current-collecting unit specified by spiral spring, around its hinged joint to upper frame, and also by traction force of cable fixed on stem of current-collecting unit.

EFFECT: simplified design and higher quality of current collection.
