Rail testing attachment for wagon - uses pre-tensioned telescopic legs between testing frame and body

摘要

The rail testing trolley has a testing frame, journalled but transversely displaceable on the trolley body, and tracked by at least one wheel set. Pretensioned telescopic legs (20, 22) inclined towards each other, are positioned between the trolley body (4) and the testing frame (10) in pairs, in a V-shape, with, in the central position of the testing frame, opposite horizontal pressure force component of the same size. The divergent ends of the springs are hinged to the trolley body, and the spring pre-tension is adjustable. Two opposite acting steerages are hinged with their opposite ends to the body, to guide the testing frame on the body without free play. The facing steerage ends are connected via a compensation lever, hinged centrally to the testing frame.
