It should be understood that specialists in this field of technology will be able to offer other embodiments of the invention and that some of its details can be changed in various other aspects, without going beyond the essence and scope of the present invention. Accordingly, the drawings and the detailed description of the device for rail fastening of the turnout are illustrative, but not restrictive.

The best embodiments of the invention

The device 1 (see Figs. 1, 2) for rail fastening of the switch (hereinafter referred to as the device) contains a support lining 2 for placing a frame rail 3 on it, a cushion 4 with a support section 5 for supporting and sliding the wit (not shown in the figures) .

Support lining 2 and pillow 4 are made of a single piece of high-strength composite material, which eliminates the technological processes of their mutual positioning and connection, also eliminates their destruction during operation, thereby increasing the operational reliability of the device 1 for rail fastening switch.

The cushion 4 contains wedge-shaped section 6 and an end 7 located on opposite sides. The wedge-shaped section 6 is directed to the flange 8 and forms a gap с with the base 2a of the support pad 2 for accommodating the section of the sole 3 and the frame rail 3. The said wedge-shaped section 6 is designed to support the wagger.

The above pillow 4 can be equipped with a metal lining 9 with a horizontal section 10 for supporting and sliding the wit (see Fig. 3-6). The horizontal section 10 is supplied by

- 2 029041

at least one longitudinal groove 10b located along the longitudinal axis b of the support lining 2 and across the wag. In the specific example of execution, the horizontal section 10 is corrugated and is formed by alternating longitudinal projections 10a and grooves 10b located along the longitudinal axis b of the support lining 2 and across the tongue. During operation of the device 1, a lubricant is applied to the metal cover 9, which accumulates in the above-described grooves 10b and is maintained when the tongue slides along the horizontal section 10 or its longitudinal projections 10a, if the horizontal section is corrugated.

Oppositely located peripheral sections 11, 12 of the metal lining 9 are bent so that the latter (9) can be reliably held on the cushion 4. In the specific embodiment, the peripheral section 11 in the longitudinal section of the metal lining 9 is made in the form of a hook, which allows the peripheral section 11 securely hook on the wedge-shaped section 6 of the cushion 4, and the peripheral section 12 is curved and presses the end 7 of the cushion 4.

The metal lining 9 can be made in the form of a fixed element of the cushion 4 (see Fig. 7).

The support portion 5 of the cushion 4 can be provided with at least one longitudinal groove 5b located along the longitudinal axis b of the support pad 2 and across the tongue. In a specific example of execution, the support section 5 is made with alternating longitudinal projections 5a and grooves 5b forming a corrugated surface.

In case the device 1 is not equipped with a metal lining 9, a lubricant can be located in the longitudinal grooves 5b.

In case the device 1 is provided with a metal lining 9, then the mating of the corrugated surface of the supporting section 5 of the pillow 4 with the counter surface of the corrugated horizontal section 10 of the metal lining 9 prevents the latter (9) from moving across the pillow 4, i.e. across the longitudinal axis b.

The cushion 4 is provided with side protrusions 13 located on opposite sides of the support section 5. The side protrusions 13 are made in cross-section of an L-shaped form and are connected to the base 2a of the support lining 2 and the sides of the cushion 4, forming through free zones 14, in particular longitudinal holes, for installation of elastic holders 15. The shape of the side projections 13 prevent the elastic holders 15 from moving sideways and upwards, which increases the reliability of the device 1.

In the free zones 14, in the upper portions 16 of the lateral projections 13, local thickenings (not shown in the figures) can be formed to rest against the elastic holders 15.

The upper portion 16 of each of the side projections 13 can be arcuately concave on the outer side, which allows the upper portion 16 to abut the convex inner surface 16a (see FIG. 6) into elastic holders 15 installed in free zones 14.

On the outer side of the side projections 13, transverse ribs 17 can be formed, made in an L-shape, which increases the strength of the side projections 13. This is especially true for thin-walled structures.

The support lining 2 is provided with transverse protrusions 18, on which the elastic holders 15 rest on one of their peripheral portions. The transverse protrusions 18 are located on opposite sides of the cushion 4 opposite the free zones 14. The transverse protrusions 18 can be connected to the sides of the cushion 4.

Elastic holders 15 can be made in the form of horizontally elongated plates. The possibility of making elastic holders 15 by one integral element of the U-shaped form is not excluded.

The support pad 2 and the pad 4 of the device 1 are made by injection molding from a high-strength composite material, such as polyethylene terephthalate, polyamide-6, polyamide 66, in particular RL66-OR35, or another material.

In the rail fastening of the switch (see Fig. 8, 9), the flange 8 limits the lateral movement of the frame rail 3. A terminal 19 is installed on the flange 8, pressing the sole 3 and the frame rail 3 to the base 2a of the support lining 2. Elastic holders 15 are installed in free zones 14 of the side projections 13 and each of them rests in one peripheral section on the base 3a of the frame rail 3, and the second peripheral section on the corresponding transverse projection 18, while the central zone of the elastic holders 15 is tucked down by the upper section 16 side new protrusions 13.

The above-described device 1 is devoid of the disadvantages indicated in the analogue and the closest analogue, it is technologically advanced in the manufacture and assembly of rail fasteners. The support pad 2 and the pillow 4 are made with a single piece of composite material eliminating welding joints and the destruction of the pad 2 and / or the pillow 4, and the metal pad 9 with the longitudinal groove 10b or the corrugated section increases the strength of the device 1 and ensures perfect slip of the tongue, which generally increases the operational reliability of the device 1 and rail fastening switch;
