The invention relates to the field of railway transport, namely to the brake equipment for rail vehicles, in particular to the disc brakes.

Known as wheel hub for rail vehicle with two wheels connected with axle and brake discs, interacting with the surface of the wheels, and of the elastic ring, providing the necessary frequency drives, or installed inside of the wheel rim massive ring rubber gaskets (US patent # 7625030, CL B60B 17/00, publ. 2009).

The disadvantage of the invention are one friction surface on each side of the wheel and at higher speeds the movement of rail transport will require increasing the forces pushing on the brake pads, which increases the temperature in the friction zone reduces the reliability and efficiency of the disk brake.

It is known, the disc brake system TMH containing installed in a vehicle a single device with the disk ticks on each wheel undercarriage, wedge-shaped nodes are rigidly connected to the brake beams and contain a couple of videos with the possibility of rotation on the respective edges pair swivel levers, located inside the unit disk with the tongs. (US patent # 7341128, CL B61H 13/00, publ. 2004).

The drawbacks are:

- a system of levers to drive ticks complicates the design and reliability of work;

- absence of Autonomous drive of rotation of the levers does not ensure the universality of the equipment and reduces the technical capabilities of the device.

Known disc brake wheels, taken as a prototype containing iron brake discs, brake pads and plastic plates, lever transmission with two two shoulders levers associated with one hand with brake blocks and on the other - with cone, controlled pneumatic brake cylinder, brake drive bracket with the two sides of the drive wheels. (Gutkin L.V., Dimant YU.N., I.A. Ivanov Train ER 200. - M: Transport, 1981, UDC 629.423.2: 621.3.024, page 60, 63).

Disadvantages disc brakes are:

- presence of tick parallelogram mechanism increases the width brakes, which complicates its use in the running of small trucks and narrows the technical capabilities disc brakes;

- a large number of structural elements (springs, parallelogram mechanism) complicates the design disc brakes;

- design of brake pads does not provide increased efforts braking, for example, when driving at high speed, which increases the braking distance and reduces the efficiency of the disk brake.

The technical result of the invention is increasing the efficiency of the braking process, reduce the size of the brakes, the simplification of the construction and expansion of technical opportunities of the brakes.

This technical result is achieved by the fact that disc brake wheels, containing a body, brake disks, mounted on both sides of the drive wheels, brake pads and plastic plates, lever transmission with two two shoulders levers associated with one hand with brake blocks and on the other - with a controlled pneumatic brake cylinder and the springs to suck brake pads, brake disc, swivel axis for fixing two shoulders levers; disk brake equipped with at least two frictional disks located on both sides of the drive wheels and the set ends with the brake discs, internal friction discs made in the form of segments secured by axis to the chassis and external friction discs are made in the form of rings of segments, fixed by means of axes on the brake disc pads for connection of segments screws, friction discs contain additional springs installed on axes for education gap on the friction surfaces.

Disc brake wheels contains a body 1, brake disks, 2, mounted on both sides of the disc 3 wheels 4, brake pads 5 with plastic lining 6, lever transmission with two two shoulders levers 7 related to one side with brake blocks 6 and on the other - with a controlled pneumatic brake cylinder 8 and springs 9 to suck brake pads 5 from the brake discs 2, swivel axes 10 for mounting two shoulders levers 7; disk brake equipped with at least two frictional disks 11 and 12, located on both sides of the disc 3 wheels 4 and the set ends with the brake discs 2 forming with plastic lining 6 brake pads 5 at least three of the friction surface, 13, 14 and 15, internal friction discs 11 made in segments of 16, fixed by means of the axes of 17 building 1, and the external friction discs 12 made in the form of rings of segments 18 fixed axes through 19 on the brake disc 2) with overlays of 20 for connection of segments 18 screws 21, friction discs 11 and 12 contain additional springs 22, installed on the axes 17 and 19 for education gap on the friction surfaces, 13, 14 and 15.

Disc brake wheel pairs works in the following way. When the signal about the need braking power cavity pneumatic brake cylinder 8 connects to the air supply, springs 9 and 22 compressed and two shoulders levers 7 turn around the hinge axis 10, with the brake pads 5 with plastic lining 6 approach friction disks 11 and 12 on the value of L, which, interacting on the friction surfaces, 13, 14 and 15 with brake discs 2, create a braking torque of friction, which through axis 17 and 19 transmitted brake discs 2, and is in the process of braking. In the process of movement of the vehicle, the air pressure in pneumatic brake cylinder 8 reset and springs 9 and 22 is the challenge ROM 11 and 12 and education gap on the friction surfaces, 13, 14 and 15. The presence of three of the friction surfaces, 13, 14 and 15 of the brake discs 2 increases the friction torque, it may reduce the size of the brakes, simplified design, correspondingly reducing the mass of mechanisms clamping unit disc brakes and expansion of technical opportunities of the brakes due to the use of various mechanisms, as well as improving the efficiency of the braking process by means of selection of material plastic linings 6 and friction discs 11 and 12.
