    The invention relates to a hydraulic piston wagon retarder for braking railway wagons with dehghfer having telescopic parts located in a support tube provided with an exhaust hole and driven from a respective wheel of the railway wagon, with the piston wagon retarder mounted using a holder mainly on the rail.
    A hydraulic piston car retarder for braking railway rolling stock, mainly mounted on a rail, contains a damper with a support tube, in which there are two telescopically connected parts, one of which has a head at its end for interacting with wheelsets of rolling stock, and has at least one other; she has at least one vent hole.
    A disadvantage of this device is that the holder is secured by axles that pass through the vertical rail neck, as a result, this rail neck not only incurs relatively large expenses for creating through holes to the rail neck, but to a large extent the rail neck weakens . The cylinder blocks with the piston, and therefore telescopically slid into each other, parts 1 of the hydraulic dampers are unprotected in known devices against shocks and impacts, as well as contaminants, and the moving masses are relatively large. The device requires large maintenance and installation costs.
    The purpose of the invention is to increase the convenience of maintenance and increase the service life.
    The goal is achieved by the fact that a hydraulic piston car retarder for braking railway rolling stock, mainly mounted on a rail containing a damper with a support tube, in which two telescopically connected parts are located, one of which has at its end a head for interaction with wheel pairs of rolling stock and a friend has at least

    one vent hole, provided with a guide sleeve, installed with the possibility of moving along the damper axis between the support tube 5 and the telescopically connected parts under the head, while one of the telescopic parts is detachably connected to the head, and the other rests on the support tube with the possibility radial and angular displacements relative to the latter.
    In addition, the support tube is made with a shoulder for mounting on a support.
    The support tube on the lower end t5 side is rigidly connected to a plug made with a recess in which a ball bearing is placed, located on one of the telescopically connected parts of the damper. 20 Mentioned chickpea head is made of elastomeric material.
    A shock absorber is placed between the head and one of the telescopically connected parts.
    25 On the upper surface of the head there is a wear-resistant metal, reinforced layer or carbide layer.
    FIG. 1 shows & n hydraulic 3Q piston car retarder, partial longitudinal section; in fig. 2 - the same, side view; fig.Z-moderator option.
    A railway car wheel 1 (not shown) rolls along a rail 2 with a vertical neck 3 and a sole 4. At the same time, the flange 5 of the wheel 1 presses down the head 6 of the hydraulic damper 7 when moving, therefore, it is centrally in the X direction against the hydraulic effort of damping. The valves in the piston retarder correspond to the designs of hydraulic piston wagon retarders (not shown).
    The dampers 7 can be adjustable in terms of speed. moving cars, therefore, can regulate the speed and retention of unexposed railway wagons.
    Each damper 7 consists of two telescopically connected with a change along the length of the parts 8 and 9 inserted into each other, which form a cylinder block with a piston. Telescopic parts 8 and 9 also include a hydraulic damping medium and valve devices (not shown). FIG. 1 shows a telescopic part 8 having a smaller diameter, which is located on the rear end of the damper 7 facing the wheel 1 and here through a spring retaining ring 10 or in another detachable manner connected to the head 6. The latter (FIG. 1 and 2) is in the form of a lens and It goes upwards and enters the guide tube 11 and, using a thread, connects 12 to it. The guide tube 11 is located coaxially with those scopically connected parts 8 and 9. Due to this, the guide tube 11 moves together with the head and the telescopically connected part 8 in the longitudinal direction of the damper 7. FIG. Figure 1 shows the compressed damper 7 by dashed lines, circled lines — the installation position, the damper 7, in which it is not loaded by the wheel 1. Telescopically connected parts 8 and 9 and guide tube 11 are coaxially aligned in the support pipe 13, which is on its The end 14 facing the ground is hermetically sealed by a welded plug 15. The plug 15 simultaneously serves to support the telescopic part 9, which is mounted on the plug through a spherical support 16. The guide tube 11 is displaced longitudinally and without bias, along two R located at a distance from each other, mounted in the support pipe 13, sliding bearings in the form of rings 17 and 18. At the upper end of the support pipe there is a seal 19, The telescopically connected part 9 can also be located at the top in diameter, while telescopically connected to detail 8 is at the bottom. In this case, it is possible to place the support 16 not below, as shown in FIG. 1, and at the top, by making the head 6 in the form of a hemisphere and from a rubber elastomer. Further, it is possible to place the top and the bottom, therefore, in the region of the head of the beams in the area of the plug 16, respectively, along a single spatial hinge in order to eliminate the tilt of the telescopic parts 9 and 10 during eccentric application of force. The moderator has a retaining strap 20, which has a supporting surface 21 parallel to the underside of the sole A, on which the sole 4 lies. A support 22 is connected to the retaining strap 20, on which the supporting tube 13 is supported, via an intermediate spacer ring 23 with an annular collar 24. The support 22 has a cylindrical bore hole 25, through which the support 13 passes. With the support 22, a protective protrusion 26 is connected, which is provided with a corresponding sole 4, a bevel 27, which as completely as possible lies on the corresponding sole bevel 4. Otherwise, a recess 28 is provided between the support surface 21 and the support legs 22, in which a portion of the sole 4 of the rail 2. In FIG. 1, the retaining strip 20 protrudes on the opposite side of the support 22 to the sole area so much that there is a place for two longitudinally arranged rails 2 in the distance from each other through holes, of which (Fig. -1) only one hole 29 is visible, whereas at the other through hole, 30 (FIG. 2) shows only an axial line. Through holes 29 and 30, respectively, pass through one screw, of which only screw 31 is depicted (Fig. 3). These screws have a head 32, which from the bottom with a positive fit is inserted into the proper recess of the corresponding through hole 29 respectively 30 and thereby prevents from cranking. From above, the clamping element 33 engages the protrusion of the retaining strip 20 and the adjacent part of the base 4 so that after tightening the nuts 34 on the screws 31 the hydraulic piston car retarder is clamped to the rail 2 by clamping. AXIS 36 of the rail 2. The ejection open 37 is provided in the support tube 14 and connects its internal cavity with the outer atmosphere. Several such openings can be attached, thus creating a damper cooling due to the pumping effect.
