Abstract

This invention relates to a transport engineering, in particular to coupling devices to semi-articulated articulated vehicles. The purpose of the invention is to increase the reliability and durability of work. The hitch device of the half-frames of an articulated vehicle contains articulated joints made in the form of nodes of rotation of the half-frames relative to each other in the horizontal and vertical transverse planes of the vehicle, including carrier pins. Semi-frames 1, 2 are connected by one pin, the middle part of which is covered by an element of one semi-frame with gaskets 14 installed on horizontal upper and lower planes of this element, which interact with the flat surface of half-cylinders 5, whose spherical surfaces are turned in different directions and interact with the counter surface bases 6, which are fixed by the sides in made in the form of a fork of one of the half-frames. The surfaces of the bases 6, opposite to the spherical ones, are pressed by the flat surfaces of conical pivoting washers, inside of which there are cuts with cross sections in the transverse plane passing through the axis of the pivot, in the form of equipotent trapezoids interacting with flat faces made at the ends of the pivot. Swivel washers are installed through sleeves in one of the half-frames. 8 il.

When driving on a straight level road, the hinged joint 3 is in the position as shown in FIG. five.

The loads acting on the hinge joint 3 are perceived by the bearing chick 4, which, if there are flat faces 10 at the ends, makes planar contact with rotary washers 7 G1 of the front nurarama 1. In this case, the load on the rotary Ilib 7 is equally distributed.

When the articulated vehicle is moving in a turn, the turning unit of the half-frames in the horizontal plane works. The guide 12 of the rear half-frame 2 is rotated relative to the bearing frame 4 and the gaskets 14.

When moving but straight when moving a single obstacle, the articulated joint 3 takes a position, as shown in FIG. 6. Works node-turning half-frames in the vertical plane. The half-cylinder elements 5 are rotated relative to the bases 6. The sanding tongue 4 rotates in the slots 8 of the pivoting shields 7, allowing the rear guide 12 of the rear nuraram 2 to rotate relative to: and the front half-frame 1.

When moving an obstacle when the articulated vehicle is moving, rotary washers 7 work on the top. To rotate the carrier H1 trunk 4 when folding the half-frames (from position 1 to position II) at an angle a (FIG. 8), the swivel washers 7 turn relative to the sleeves 9 in the places of their conical connection under the action of forces arising in the month of I. interaction of flat faces 10 with the edges of the grooves of 8 turning washers 7. In this position, the turn nodes of the half-frames work in the same way.
