ABSTRACT:
A rail vehicle, especially self-propelled vehicle, in which pulling and braking forces are transmitted between pivotless bogies and the main frame of the rail vehicle, and in which on both vehicle sides, symmetrically with regard to the longitudinal central axis of the rail vehicle, pressure and pull rods are on one hand connected to the outside of the bogies and on the other hand to hydraulic cylinder-piston systems connected to the main frame. The corresponding working chambers of the hydraulic cylinders on both sides of the vehicle are respectively adapted to communicate with each other. On each vehicle side between two bogies, there is arranged one hydraulic cylinder-piston only which has two separately acting working pistons each respectively connected to a pressure rod and pull rod. Each of the three working chambers formed by the above mentioned two working pistons of the hydraulic cylinder-piston systems is on one vehicle side adapted to be connected with the corresponding working chamber of the hydraulic cylinder-piston system arranged on the other vehicle side.
