    (54) WHEEL PAIR FOR VARIOUS WIDTH
    one
    This invention relates to railway transport.
    Constructions are known in which the wheels of each car axle can be displaced by two well-defined distances, corresponding to two different distances between the legs. In these two positions, the wheels are locked using intricate mechanisms, usually containing springs and transversely displacing bushings, which fix and block several locking valves. The operation of these mechanisms is carried out in a single railroad adapter, where, under the action of a command from the outside, the wheels are unlocked and shifted to the position required for the new one, and then locked again.
    A carriage axle structure is known in which both wheels are mounted freely on axially unrestricted roller bearings on a non-rotating axle. On the inner side of each wheel a double thrust bearing is mounted, the middle ring of which is connected to a non-rotating sleeve, which covers the axis
    GOATS
    almost to the middle. At the inner end of the liner there are two side spikes on which one vertically movable fork rests with two pairs of slots defining the positions of the wheels in two interleave x.
     The fork is located symmetrically in the middle of the carriage axle, pressed against the spikes by a spring and guided by a vertical bolt, which is located along the axis of the spring. Under the axle to the fork mounted roller, which in
    The 10th transitional section rolls on a sloping ridge. In this position, the fork is raised, the wheels are unlocked and mixed into a new position. When the tire is tilted back, the fork moves onto the spikes that correspond to the new inter-path.

    The disadvantages of this design are as follows. The locking mechanism located in the middle of the carriage axle has a large volume, as a result of which it is impossible to use the said carriage axle.
    20 for cars with the most common type of brake system - shoe with triangular brake shafts and centrally located brake system. Another disadvantage of this solution is that the axial forces are transmitted via a vertical bolt located along the axis of the spring, this bolt being fixed in a cantilever and weakening the axis in its most loaded part. In addition, when releasing the locking mechanism, it is not possible to align the vehicle with the axis of the road. A characteristic feature of all known locking mechanisms is that they are manufactured with great precision, have insignificant gaps, and their maintenance in the locked position is provided by spring mechanisms that are complex and cannot always guarantee the absolute reliability required in this case. In addition, the known constructions are intended for two inter-tracks and do not solve the problem of using one car axle with a larger number of inter-tracks. The purpose of the invention is to create a wagon axle for a quick and convenient transition during movement. e. means between all kinds of normal and wide interdupusations without the use of manual labor and complex locking mechanisms. In addition, the proposed wagon axle should provide the possibility of its installation to the existing crew parts of standard means, while respecting the simplicity, lightness and compactness of the design. This goal is achieved by the way that the wheels of each carriage axle are mounted on sleeves that cover both ends of the axle by means of roller bearings fixed to the sleeves on the outside of the wheels and fixed in the transverse direction. prisms that are fixed in the aforementioned boxes of boxes. Each box of axle box consists of vertical walls, to which stops are fixedly attached, in the lower part of the axle box fixed guides are fixed, with the lower side of each axle box shaped as a side-by-side. Each axle box is connected with the rolling stock frame by the axle box jaws that enclose it. The lower part of each sleeve in the area of the axle box is cut, and in one transverse section. the channel. axis by means of bolts fixed remote lock. It is located between the rails at the bottom of the box of the axle box. Brackets are installed under the side axle parts, which are fastened to the rolling stock frame with nuts. FIG. 1 shows the carriage axle in the position for the widest inter-path, a cross section; in fig. 2 - the same. for the case of passing through the second section of the transition device; in fig. 3 - carriage axle, top view and horizontal half section; in fig. 4 - a trolley equipped with a wagon axle for various interstitials, side view. The car axle consists of axle 5 and independent traveling wheels 2, which are mounted on roller bearings 3 on sleeves 4. Sleeves 4 cover both ends of axis 5. Fixing each sleeve 4 with the running wheel 2 to axis 5 is carried out using a locking mechanism. This mechanism is located in the box axle box 15 on the box 8, on which are the elements of the primary spring suspension 9. Box axle box 15 consists of vertical walls 14, to which are fixedly fixed stops 16, made in the form of vertical parallels. The vertical walls 14 of the axle box 8 are operated by friction (frustration) dampers 17 of the primary spring suspension 9. The locking mechanism consists of two longitudinally arranged prisms 18 at the upper end of the axle box 15, through which the load from the axle 8 is transferred to fixed above the sleeve 4. It has bodies 20. The bodies 20 are provided in their upper part with several pairs of longitudinal channels 21, which correspond in shape to prisms 18, and in their number they are equal to the number of inter-paths. In the example shown, there are three of them. In the longitudinal direction, each body 20 is guided by the vertical walls 14 of a box of box 15. In the area of box 8, the bottom side of each sleeve 4 is cut under axis 5, where in the transverse channel 22 of axis 5, by means of bolts 28, a remote lock 24 is fixed. The ends of remote lock 24 are guided in the longitudinal direction by the vertical walls 14 of the box of the axle box 15, and in the transverse direction by guides 25, which are fixed at the lower end of the box of the axle box 15. The axle box 8 is surrounded by the axle forks 10, which fix it horizontally of relative frame 11. Under the side portions axis 5 extending brackets 26 which are secured by a nut 27 to the bogie frame 11 (rolling). The lower part of each axle box 8 is framed in the form of a side-by-side 28, which in the second section of the transition device rests on a longitudinal stationary tire 29 having a lateral ridge (flange) 30, which ensures strictly longitudinal movement of the trolley. In this section, the running wheels 3 are guided by the side guides 31 enclosing them. In a transition device located between two interleaves, the position of the running wheels 2 relative to axis 5 is changed as follows.
    In the first section of the transition device, the wheels 2 constantly hang in the air, and the rolling stock begins to be transmitted by the axle boxes 8 by means of slides 28 to the longitudinal stationary tires 29. The whole set consisting of the wheels 2, axles 5 with sleeves 4 and bodies 20 11a downwardly with respect to the axle box 8, the prisms 18 coming out of the longitudinal channels 21. At this moment, the running wheels 2 are unloaded and, by covering them with their side guides 31, are shifted laterally by a distance corresponding to another In this time interval, the prisms 18 are installed above another pair of channels 21 and gradually hook on them when the carriage axis passes over the third section of the transition device. At this moment, the running wheels 2 are again on the rails, and the longitudinal stationary shells 29 under the axle boxes 8 are interrupted. This completes the retuning of the wagon axle for movement along another inter-track.
    If during the construction of the locking mechanism the condition that the height of engagement of the prisms 18 with longitudinal channels is met. Lami 21 HI is smaller than the gap between the lower part of the axis 5 and the bracket 26 when the rolling stock is not loaded, prospectively less than the gap hj between the lower part of the remote lock 24 and the stops in the lower part of the axle box 15 and if the gap H between the lower part of the axis 5 and the bracket 26 is less or approximately equal to the static compression of the primary spring suspension 9, then an automatic, reliable locking of the mechanism is ensured.
