Description:
A rail running gear comprising two rail axles (1), equipped with running rollers (2) and drive drums and control arms, the first ends of the control arms (4) being attached to the rail axles (1) and the second ends of the control arms (4) being connected to the first brackets (6), which are attached to the drive bridges (7). The control arms (4) are connected to the second brackets (10), to which the hydraulic actuator pistons are pivotally attached. The first brackets (6) are attached, by means of spring stirrups (8) to the drive axles (7) under the leaf springs (9). To the lower surfaces of the drive bridges (7), in the spring mounting planes (9), second brackets (10) are attached by means of spring stirrups (8), in which the pivot stubs of the hydraulic cylinders are fixed. The bracket (10) consists of a plate from which parallel horizontal walls with perpendicular vertical walls extend. The plate (10) has holes through which the spring stirrups (8) pass. The vertical walls have holes into which the pivots of the hydraulic actuators enter. The vertical walls are attached to the horizontal walls by means of bolted connections passing through threaded holes in the horizontal walls and through holes in the vertical walls.
