Abstract
A device for detecting obstacles for a rail vehicle includes a pilot bar, which is retained on the bogie frame of the rail vehicle in front of the wheelset that is positioned first in the direction of travel via a mounting retainer, wherein the mounting retainer is formed by vertically arranged spring elements, in particular leaf springs, where each leaf spring is fastened at an upper end to the bogie frame and at a lower end to the pilot bar, where each leaf spring includes a stress-strain converter which is arranged between the upper end and the lower end on a broad surface of a leaf spring, and where each stress-strain converter is connected to an on-board evaluator via a signal-conducting connection.
