Description

The invention relates to railway transport and relates to the design of running gears for rolling stock intended for movement on railways with different track gauges.

The purpose of the invention is to increase the reliability and simplify the process of transition from one track to another.

FIG. 1 shows the proposed trolley, side view; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. one.

The cart consists of two independent side frames 1, independent running wheels 2 mounted on semi-axes x 3 in boxes 4 located on both sides of the side frame 1, a bolster 5 passed through the spring openings of the side frames 1 and resting on the spring sets 6 , an additional beam 7, located parallel to the bolster 5. The ends 8 of the additional beam 7 are made with non-braking threads interacting with threads in the tides of 9 side frames 1. At the same time, the left-hand thread is on one end and the other is right. The additional beam 7 is installed in the sub-racks 10 and 11 on the carriage 12, which can move in the transverse direction by means of the rollers 13 on the spring plate 14 of each side frame 1. The spring sets 6 rest on the horizontal surfaces of the carriage 12. To the body 15 of one The carriages 12 are attached to the end face of the additional beam 7 by a pneumatic rotation stopper for the additional beam 7, made in the form of a cylinder 16, in which the piston 17 moves with rods 18 and 19. Between the cover 20 of the cylinder 16 and the piston 17 it There is a return spring 21. The end of the rod 18 is made with longitudinal external slots, which interact with corresponding slotted grooves made at the end of the additional beam 7 along its longitudinal axis. The end of the stem 19 has a square head that interacts with a square hole in the cap 20. Compressed air is supplied to the cylinder 16 from the reserve reservoir of the brake system (not shown).

The cart works as follows.

The transition to another gauge takes place on a special path with three sections, the middle of which has a variable gauge width. Before the trolley passes through the middle section, air is supplied to the cylinder 16, the piston 17 moves to the right, the splines 18 are extended out of the grooves of the additional beam 7. The square end of the rod 19 leaves the opening of the cover 20, which indicates that the stopper is in the open position.

When the trolley is moving in the middle section, there is a gradual lateral

 the displacement of the side frames 1 due to the forced action on the wheels of the two rails and counter rails. As a result, the additional beam 7 rotates in the threads of the arms of the frames 1, ensuring the movement of the frames 1 on

5 required value. At the same time, the carriages 12 connected to the auxiliary beam 7 are moved on the rollers 13 along the spring plate 14, ensuring the normal position of the spring sets 6.

After moving the cart to the site with

0, the supply of air to the cylinder 16 is stopped, the return spring 21 moves the piston 17 to its original position, and the rod 18 again stops the additional beam 7 from turning.
