(57) Abstract:Usage: in the brake equipment of railway rolling stock. The inventive brake shoes contain in contact with the disk, the node suspension boots and clamp tick type, pivotally connected with shoes. Two-stage hinge connects the Shoe with lever tick mechanism. One of the axes of such a joint should be parallel to the axis of the hinge suspension clamp tick type to the frame and allows freedom of self-Shoe when asenapine movements of the wheelsets relative to the truck. The other parallel to the axis of the car and gives you the freedom of self-Shoe when Kreinovich movements of the bogie relative to the wheelsets.

The invention relates to the field of brake equipment of railway rolling stock.Known disk brake suspension of shoes to the frame of the truck, unloading the axis tick from a reactive mechanism braking effort. Tick the mechanism attached to the frame of the truck with one hand by rod boots, and on the other directly. Point direct mounting to the frame can b is alinia to the frame should be made of the hinge. The hinges needed to compensate for the inevitable displacement of the wheelset relative to the bogie frame, errors in the location of the attachment surfaces on the frame and brake lining wear 
A disadvantage of the known constructions of this type is the lack of angular Kreinovich oscillations of the axis of the wheelset relative to the sprung truck. Especially intensive kranovye movement of the truck at high speeds. The amplitude of oscillations can reach 500 mm on the basis of a rut. Commitment to the reliability of the brakes at high pollution of the air flow of solid particles and water (ice) dictates the need to reduce the gaps between the pads of the shoes and discs, which in turn exacerbates the "unauthorized" local pad wear increases the energy costs of movement, and worse, it leads to violent interaction of the parts brake down to their destruction.The objective of the invention is to improve the reliability of the disk brake.The required technical result is achieved by the fact that each Shoe is attached to his arm clamp tick type two-stage hinge, and the first axis of the two-stage hinge parallel to the longitudinal about the power of the hinge parallel to the axis of the hinge, connecting the clamp lever to the frame of the truck (neutralization axial movement of the wheelset relative to the truck), and the site of a suspension made of a parallelogram. The first and second axis of the hinge can be overlapping.In Fig. 1 shows a diagram of the installation disc brakes on the truck needed to illustrate the relationship of composition disc brakes on the truck with the design of the proposed two-stage hinge; Fig. 2 is conventionally rotated view of the parallelogram suspension; Fig. 3 conventionally rotated view of the clamp tick type; Fig. 4 separately shows the brake Shoe in the context of explaining the two-stage design of the hinge; Fig. 5 - additional incision two-stage hinge.Disk 1 (Fig. 1-3) located on the axis of the wheelset truck, compressed pads 2, 3, which in turn affect the levers 4, 5, joint coupler 6 in the clamp tick type. The force is generated in the brake cylinder 7, located on tick-borne mechanism on the opposite the shoes sides. Response inhibition perceived power beam 8 truck through two thrust 9, 10 parallelogram suspension. The third point of attachment of the brake to the cart hinge 11, situated on the river is dynamic shoes 2, 3 with the corresponding levers 4, 5, formed as two odnopodezdny rotational pairs: the liner 12, the lever 4 and the liner 12, the finger 13 with crossed axes. The direction of the axis predetermined by the setup of the brakes on the trolley (Fig. 1). To compensate for the axial displacement of the wheelset with disc 1, it is important that the axis of the finger 13 is parallel to the axis of the hinge 11. For angular Kreinovich movements of the pair of wheels relative to the truck it is important that the axis of the liner 12 is parallel to the longitudinal axis of the truck or rail 14. Washers 15 (Fig. 4, 5) serve to limit the play of the lever 4 in the direction of the axis of the finger 13 and have at one end a flat surface allowing rotation of the Shoe 2 around the axis of the finger 13, and the other cylindrical, allowing rotation of the Shoe 2 around a horizontal axis (parallel to the longitudinal axis of the truck).Axis two-stage hinge can be made to intersect.Disc brake operates as follows. When compressed air in the brake pneumatic cylinder 7 rotates the levers 4, 5 around the axis of the coupler 6 and compress pads 2, 3 disk 1, by braking the pair of wheels of the truck. In the event of axial displacement of the wheelset and disc 1 (for high-speed trains amplitude settling included brake or not (in disinhibited state, the gap between the Shoe and the disc should not exceed a few millimeters) malfunction of the brake is prevented by operation of the hinge rod 9, 10 (Fig. 1, 3) and two-stage hinge (Fig. 4) around the axis of the finger 13. When the angular Kreinovich movements disk 1 failure of the brakes is prevented by the operation of the liner 12 (Fig. 4, 5) and washers 15, allowing the rotation of the footing 2, 3 on the respective levers 4, 5 around the axis parallel to the axis of the truck.Thus, the introduction of two-stage hinge at the connection of the Shoe with lever tick mechanism guarantees the performance of the disk brake in any complex displacements of the wheelset relative to the sprung bogie frame high-speed trains. 1. Disc brake wheelset bogie car high-speed trains containing the disk, the shoes, the site of the hanging Shoe, clip tick type, the arms of which are pivotally connected with the Shoe, characterized in that at least one of the levers of the clamp is connected to the cart frame by a hinge, the site of a suspension made of a parallelogram, and the hinge connection of each lever clamp with the appropriate Shoe is made in the form of a two-stage hinge, and the first axis of the two-stage hinge parallel to the longitudinal axis of the carriage, and the second axis of the two-stage hinge parallel to the axis of the hinge connecting the clamp lever to the frame of the truck.2.
