Resumen
FIELD: railway transport. SUBSTANCE: proposed single-axle running mechanism makes it possible to adapt rail cars used for transportation of automobiles and consisting of two articulated rail cars and three single-axle running mechanism for running along different gauge tracks. Said mechanism includes two running mechanisms, each provided with axle-shaft, wheel W, two brake disks and two axle-boxes, built into carrying frame 1, on both ends of axle- shaft, levers to provide stability of head parts of suspension, and spring sliding shoes 3 to support single-axle mechanisms when changing wheel-to-wheel distance at changing of gauge. Direction setting system for intermediate running mechanism and two extreme running mechanisms is provided. EFFECT: enlarged operating capabilities. 8 dwg

1. Single-axle running gear with movable independent wheels for articulated car transporter wagons, which makes it possible to adapt such wagons, incorporated by two trailers connected together, so that they can run on two different track guages, and which includes two sets of running gear, each of which comprises a half-axle, a wheel (W), two brake discs integral with each other and two axle boxes (CC) which are mounted at both ends of the half-axle and which are fixed to it in the position corresponding to each track gauge by means of respective locking keys (L), characterized in that it comprises: - a carrying frame (1) in which are incorporated the axle boxes (CC) of each set of running gear and the mechanisms necessary for translating and locking the said sets; - suspension springs (2) incorporated in housings in the front parts of the carrying frame (1) and provided with vertical dampers (AV) mounted inside them; - sliding shoes (3) incorporated in the lateral parts of the carrying frame (1) and intended to support the running gear (R1, R2, R3) during the process of changing track gauge; - suspension headers (4) on which the upper parts of the suspension springs (2) bear, and in which the bells of the vertical dampers (AV) are fixed; - arms (5) for stabilizing the suspension headers (4); - hanging suspension links (6) connected at their upper ends to the suspension headers (4) and at their lower ends to supports (S) integral with the frame of the wagon; and - systems for guiding the running gear (R1, R2, R3) in order to cause the angle formed by the rim of each wheel (W) and the tangent to a curve of the track to be zero at the point of contact with the track. 2. Running gear according to Claim 1, characterized in that each set of running gear carries two locking keys (L), one for each axle box (CC). 3. Running gear according to Claim 1 or 2, characterized in that the brake of each set of running gear comprises a pneumatic actuating cylinder (7), a calliper (8) and friction linings (9) which are applied by the said cylinder (7) against half-discs fastened to the web of the corresponding wheel (W). 4. Running gear according to Claim 3, characterized in that both the pneumatic actuating cylinder (7) and the brake calliper (8) with the friction linings (9) are integral with a support (10) which is fixed to the inner axle box (CC) of the corresponding wheel (W) and can be moved as a whole with the set of running gear in order to adjust the braking system to both track guages. 5. Running gear according to any one of Claims 1 to 4, characterized in that, in the case of an intermediate running gear (R1) of a wagon, the running gear guidance system consists of two guidance lever arms (11) fitted in a horizontal position in the carrying frame (1) and of two pairs of guide bars (12, 13) which are fixed at one end to the said lever arms (11) and at their other end to the respective adjacent end faces of the two trailers constituting the wagon. 6. Running gear according to any one of Claims 1 to 4, characterized in that, in the case of extreme running gears (R2, R3) of a wagon, the running gear guidance system consists of a control mechanism and of a guidance mechanism proper, of which the guidance mechanism is formed by two lever arms (14) and two pairs of bars (15, 16) which are connected at one end to the said lever arms (14), the other end of the first pair of bars (15) being connected to bell cranks (17) which form part of a compensation mechanism, and the other end of the second pair of bars (16) being connected to a support of the wagon, while the control mechanism consists of two control bars (18), one of whose ends is connected to the end face of the adjacent trailer and the other end is articulated to corresponding lever arms (19), adjustable bars (20) being fitted between the said lever arms (19) and the bell cranks (17) of the compensation mechanism, and the longitudinal arms of the said bell cranks (17) being connected together by means of a crossbar (21) which also forms part of the said compensation mechanism.
