1. Pull gear for rail vehicles, substantially consisting of a support plate (2) connectable to the vehicle, a draw rod (7) which penetrates through the support plate (2), a spring (1), preferably a fraction spring, and a housing (6) surrounding the outer area of the spring (1), the draw rod (7) comprising a coupling member (7a) at its front end and a nut (4) at its rear end, and the spring (1) being supported on the one hand, from the rear with respect to the support plate (2) and, on the other, against a drawing element (5) which is arranged ahead of the nut (4) and - at least when the nut (4) is not yet mounted - rests against an inwardly directed collar (6a) of the housing (6), characterized in that the front end of the spring (1) is supported at the inner face (3a) of a base plate (3) which may be applied from the rear against the support plate (2) ; and in that the housing (6) is connected in a traction-resistant manner to the base plate (3), the spring (1), the base plate (3), the housing (6), and the drawing element (5) forming a pre-stressed assembly unit. |
