Abstract (en)
[origin: EP0261454A1] On a drawing and buffering gear are two opposing counter-balanced friction springs (1 and 2), one of which (1) is designed to absorb the tensile forces and the other (2) the compressive forces. The first spring (1) absorbing the tensile forces is relieved when compressive forces occur in the compression direction. Conversely the other spring (2) absorbing the compressive forces is relieved when tensile forces occur in the traction direction. The distance by which these springs (1 and 2) relax is at most equal to the spring travel corresponding to their respective prestressing force, any such limitation preferably being achieved by means of a stop (3 or 4) in each case. <IMAGE>
