The present invention relates to the field of railway transport and can be used in the construction of locomotives and wagons.

Known construction of rail vehicles. So in the book Technical reference railroader, vol. 6. The rolling stock. Edited Vinalopo Getresultlist, Moscow 1952, str, Fig described and shown the construction of four metal wagon length of 23.6 m Such passenger car consists of a body mounted on two biaxial trucks (str, Fig)with values (Fig, str), which are placed in the cervix of wheelset axles (Fig, str). The car is also equipped with pnevmotormoznyh equipment (str-869), consisting of brake line, brake cylinder, auxiliary reservoir and control system of the brake pads. Despite its efficiency, this car has a significant drawback, namely, that in the case of brake exhaustion during prolonged Parking of the car in when separated condition there comes a time when perhaps his motion. To eliminate this phenomenon in practice veroniki placed under the wheels wheelset shoes. This operation is time consuming, unsafe, and does not provide 100% guarantee the exclusion of self-motion of the car as often staff C what happens to lay the boots or delete them from the wheels. In the latter case, at the beginning of the movement possible derailment of the carriage from the rail, which ultimately requires additional costs to restore operational status of the car.

Also known passenger car is shown in figure 5 and described on page 49 of the book of Railway transport: encyclopedia / CH. edited NS Konare. - M.: Great Russian encyclopedia, 1994, the Design of such rail vehicle are generally similar to those described above and therefore, the shortcomings of their kind.

Therefore, the aim of the invention is the elimination of self-motion trailer rail vehicles are in when separated from locomotives at the station tracks or ways of their sludge.

This objective is achieved in that the ends of each wheelset axles rigidly fixed disks with radially arranged on the surface slots, made of magnetic material, interacting through an air gap with the response of the magnetic slots other drives, fixed against angular turns in the covers of books and spring in the longitudinal plane of the axes of the wheel pairs, and the space between the said disks through pipes connected to a spare tank pnevmotormoznyh system of the rail vehicle. Each of the other disks is nebgen lock their relative position to the books in the elastically deformed condition of the springs.

Figure 1 shows part of the journal-boxes of rail vehicles, in figure 2 one of the parts of the device, placed in a PTC site in the future, and figure 3 portion of the site intended for fixation of the rolling element, placed in a PTC site in the future.

Rail vehicle consists of a body located on the carts in the drawings, they are not shown), which has a section Buchs 1 with the lid 2. The lid 2 has rectangular holes 3, in which the movable rod 4 is rigidly connected with the other disk 5, provided with slots 6, made of magnetic material. Between the lid 2 and the other disk 5 is a compression spring 7. The rod 4 is provided with a protrusion 8 and the through hole 9, which is designed to accommodate the finger 10, clip 11 attached to the cover 2. In the axle box housing 1 also placed the disk 12 with the slots 13 made of magnetic material rigidly attached to the end of the axis 14 of the pair of wheels, and on the neck 15 axis 14 are bearings 16, fixed against axial displacement by a nut 17. The axis 14 is rigidly fixed to the wheel 18 wheel pair. In case pan 1 has a bore 19 in which is placed a pipe 20 that is associated with a spare tank (not shown) pnevmotormoznyh system of the rail vehicle.

Does the Rel the TV vehicle as follows. During its movement in the train due to the fact that spare tank pnevmotormoznyh system is under pressure compressed air (pnevmotormoznyh system of cars, both freight and passenger, presented in the book, is selected as the similar, widely known in the art and in the present application materials not described), which pipe 20 flows along arrow a in buxu 1. Excess pressure in this case is the effect on another disk 5, which occupies a position such as that shown in figure 1, clutching at the same time the compression spring 7. During braking, the pressure of compressed air in the space axle box 1, concluded between the other disk 5 and disk 12, is somewhat reduced, since the air from the auxiliary reservoir is supplied to the brake cylinders pneumatic brakes (also not shown). Thus another drive 5 under the action of compression springs 7 a few moves on the arrow In, but regardless of this, the distance between slots 6 and 13 significantly and their magnetic fields can not communicate with each other. As soon as the braking mode is stopped, the pressure of compressed air in the space between the disks 5 and 12 rebounds and additional disk 5 is moved in the direction opposite to the arrow In, compressing the compression spring 7. The described process can be the t is repeated many times, when the train is in motion with different speeds and braking modes. In the cases, when the train or a separate component of its rail-borne vehicle is in a state of long-term Parking, with time for one reason or another depletion occurs pneumatic brake pressure brake pads (also not shown in the drawings) on 18 wheels wheelset weakens and then maybe their motion. However, in the proposed design, this is not the case, since this depletion of another drive 5 under the action of the compression spring 7 is moved in direction of the arrow In such a distance that when the lug 8 will rest against the cover 2, thus providing a minimum gap between slots 6 and 13, for example, about 0.5-0.75 mm In this case due to the magnetic force of attraction that occurs between slots 6 and 13, and due to the fact that another disk 5 can rotate for the reason that his rod 4 having a rectangular cross-section, is located in the same hole 3 of the cover 2, there is a brake disk 12, and hence the entire wheelset of a rail vehicle. Releasing it will only happen when again on the arrow And into the space between the disks 5 and 12 will receive the compressed air from the auxiliary reservoir pnevmotormoznyh system. In practice, often there are cases when, for example, when rosp the NEC trains on hills or movement of individual units in the depot, self-retaining should be excluded. In this case, before will exhaust brake, fix the rod 4 by means of the finger 10, moving it in the direction of arrow C, which is placed in the hole 9, which further prevents movement of the other disk 5 in the direction of arrow C. it Should be noted that the number of the described locking devices may be installed on each wheel pair of rail vehicles in each of books 1, however, this complicates not only the design, but also increases the complexity of the proposed technical solutions in part off of him, as was described above in terms of the points of formation of trains, depots and so next. Therefore, given that currently generated magnetic materials with high magnetic induction, which can be 10000-100000 TOS and more (see, for example, the newspaper Komsomolskaya Pravda from 19.07.02,, p.3, article In Japanese there is something attractive"), specified technical solution that can be installed in one PTC site and it will provide lockup rolling stock, creating significant value of the braking moments in the interaction zone of the slots 6 and 13.

Feasibility advantage of the proposed construction of a rail vehicle in comparison with the known obvious, as it aims to promote metabolism of body is the safety of railway rolling stock.
