The present invention relates to the field of rail vehicles and can be used in the construction of passenger and freight cars.

Known brake truck rail crew. So, in the book “Technical reference railwayman” edited Aphrodai in volume 6 of “Rolling stock” (GOS. transport railway publishing house, M., 1952) str, pig in the section “Automatic brake” shown and described linkage four-axle freight wagon, consisting of pivotally-connected levers and brackets with triangulate and brake pads, driven brake cylinder connected to the reserve tank through the diffuser (see Fig str and str and str), fed with compressed air from the brake line. A significant drawback of such brakes is that in case of leakage of air from the auxiliary reservoir when long-term Parking for a single car or group of cars without engine and, consequently, the lack of pressure of compressed air in the brake line can cause the dissolution of the brakes, which will lead to self-propel cars. In practice, in order to prevent this possible phenomenon, used shoes, which are placed on the rails under the wheels of cars. Despite the effectiveness of such detent podvijenog the composition, she has flaws. First, the operation of the installation manually shoes unsafe and, secondly, there are cases when the station workers forget to set the shoes and therefore the motion of the cars is not excluded. At the same time there are cases when the same workers forget to remove my shoes, and then, upon initial movement of rolling stock last derails.

Also known brake trucks rail crews, described in the book Vigrinia “Brakes of the locomotive. The textbook for technical school of railway transport”. - M, Transgenderist, 1963 str RES and p.47-49, RIS and 34. Such brake equipment used in electric cars. In General, this braking device like those described above and therefore, the disadvantages of it is similar.

Therefore, the aim of the invention is to provide such a brake for trucks rail crews, which would exclude the possibility of self-motion rolling stock in those cases where it is when separated from locomotives at the stations or in paragraphs long sludge.

The drawing shows the General scheme of the brakes of the trolley rail crew.

This objective is achieved in that on the truck crew also pivotally mounted in parallel with the main additional cylinder, a rod which with the translational motion is located in the groove earrings, hinged on two shoulders of the lever main brake cylinder and said additional piston side of cylinder rod is spring-loaded by a compression spring and its podpornega cavity connected to the atmosphere, and his nadporshnevaya cavity is connected to a pipeline with a spare tank.

Brake truck rail crew consists of 1 horizontal and 2 vertical levers and adjusting levers 4 and suspensions 5, carrying the brake pads 6, which are in contact with the wheels 7. One of the vertical arms 2 by means of the hinge 8 is connected to a rod of the main brake cylinder 9, and the latter also by means of the hinge 10 is connected to the ring 11, a groove which is placed movably finger 12 of the rod 13 of the piston 14, is installed in the additional cylinder 15. The piston 14 is spring-loaded by a compression spring 16. The cylinder 15 is connected through a pipe 17 to a spare tank 18 connected through an air distributor 19 pipelines with the brake line 20 and the main brake cylinder 9.

Works brake truck rail crew as follows. During service braking, the brake line 20 is widely known in the art methods associated with the atmosphere, and the compressed air in the spare tank 18, through the diffuser 19 is supplied to the brake master cylinder 9. Inthis case the spindle extends in the direction of arrow A, what contributes both linear displacement and angular rotation of the vertical arm 2 and accordingly the same horizontal movements of the levers 1, regulatory levers 4, suspensions 5. Thus, the brake pads 6 are pressed against the wheel 7 by the arrow b and is the inhibition of the crew. At the same time, the vertical lever 2 moves the ring 11 in the direction of the arrow a and therefore the finger 12 of the rod 13 slides freely in a longitudinal groove earrings 11. Moving earrings 11 cannot contribute at this time, the movement of the rod 13 in the direction of arrow A, as the cylinder 15 is connected by pipe 17 to a spare tank 18, and the pressure of compressed air in it holds the piston 14 and the compression spring 16 in this state, as shown in figure 1. As soon as the need for braking crew will disappear, brake line 20 is also widely known by way of the air pressure is raised, that facilitates the connection of the main brake cylinder 9 with the atmosphere and charging the auxiliary reservoir 18 through an air distributor 19. With all the brakes again take this position, as shown in figure 1, and the brake pads 6 depart from the wheels 7 in the direction opposite to the arrow C. If long-term Parking crew without a locomotive, or in the case of rupture of the train on the rise of the brake is Magistrali 20 compressed air is completely exhausted, then last through the diffuser 19 auxiliary reservoir 18 flows into the brake master cylinder 9 and, as described above, leads a crew or group of cars to stop. However, in practice, such Parking may call for one reason or another, the leakage of compressed air from the brake cylinder 9, and then brake system (more precisely, the brake pads 6) will no longer be able to keep the crew on the incline railway, moreover, that the pressure of compressed air will fall and in the reserve tank 18. As soon as this happens, the compressed air from the additional cylinder 15 through the pipe 17 will start on the arrow to do in an emergency reservoir 18, and then under the action of a spring 16, the rod 13 will begin to move in direction of the arrow And pulling the earring 11 on the same arrow, and such movement earrings 11 will facilitate linear movement and angular rotation of the lever 2, which will cause similar movement of the other links of the lever of the brake system. In the end, brake pads 6 are adjacent to the wheels 7, excluding the movement of the crew. In the future, as soon as you produce the coupling of the crew of an engine and raise the pressure of compressed air in the brake line 20 to the normative, the compressed air from the diffuser 19 will be available in an emergency reservoir 18 and in the direction opposite to the arrow s, the latter apolnet additional cylinder 15, and his rod will occupy such position, as shown in figure 1. In this case, the lever 2 will return to its original position, ensuring a return to the same position of all parts of the linkage and the departure of the brake pads 6 wheel 7 in the direction opposite to the arrow C. Further, the process of the service braking crew and fixing it on the slopes of the railway track and in the points of sludge can recur.

Feasibility advantage of the proposed technical solutions in comparison with the known obvious, since the use of it in practice would eliminate the motion as a single wagons and groups that make up the train.

Brake truck rail crew, including the brake line connected through an air distributor with a spare tank and the main brake cylinder, hinged to the carriage, a piston through which the piston rod is connected by means of two shoulders of the lever with lever transmission control of the brake pads, characterized in that the trolley crew also pivotally mounted in parallel with the main additional cylinder, a rod which, with the possibility of translational motion is located in the groove earrings, hinged on two shoulders of the lever main brake cylinder and the piston, said additional cylinder is on the side of the rod is spring-loaded by a compression spring and its podpornega cavity is connected with the atmosphere, his nadporshnevaya cavity is connected by pipeline with spare tank.
