FIELD OF THE INVENTION The invention relates to railway transport and concerns the construction of bodywork links with bogies.

The purpose of the invention is to increase reliability and simplify the design.

FIG. 1 shows the arrangement of the device on the trolley frame, general view; FIG. 2 is a view A of FIG. ; in fig. 3 is a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2

The device body interface with a trolley consists of four supports, each of which contains a support plate 1 mounted on the frame 2 of the body and a support plate 3 mounted on the frame of the trolley 4. Between the support plates 1 of the adjacent supports on the frame 2 of the body there is a gear rail 5 , and between the plates there are 3 adjacent supports on the frame 4 of the trolley - a gear rack 6. In each support there is a cylindrical 10 between the plates 1 and 3

and the divider plane of the rails 5 and 6 coincides with the plane of the support plates 1 and 3.

Gear racks 5, 6 can be replaced with a roller chain (in Fig. 2, both the rail and the chain are shown).

The device works as follows.

The rolling bodies 7 perceive static and dynamic loads from the body and ensure the rotation and relative movement of the carriage when passing the curves. In this case, the mutual position of the rolling bodies 7 relative to the longitudinal Axis is guaranteed by the engagement of the gear 10 with the rails 5 and 6.

With the passage of the curves, the rolling bodies 7 roll between the base plates and 3, and if they are still relative, they rotate relative to the rod 9, while the rod together with the gear 10 moves in the direction perpendicular to the front axle of the vehicle. Limit rotation serve stops 12, turn

Nirn is connected to the axes of 8 rolling bodies 7. 5 at the end of the rod 9. When the axis 8 is relative, the trolley 11 is mounted on the frame 4 of the cart for the rod 9 during its longitudinal movements, and on the frame 2 of the body there are stops 12, which limit these movements.

The rod 9 in the place of the hinge connection with the axis 8 has a U-shaped profile, while the horizontal profile shelf has two sections 13 and 14, limiting the angle of rotation of the axis 8 with the rolling bodies 7. The section 13 parallel to the guide axis 8 limits the deflection of the rod from the position, perpendicular to the axis, only by the size of the gap between the horizontal profile flange and the axis. Section 14 restricts the rotation of the axis 8 to coincide with the radial position centered on the axis of the pins 15. The spring 16 provides for the retention of the axis 8 in this position.

The diameter of the pitch circle of the neck is 1% and 10 is equal to the diameter of rolling bodies 7.
