Description

(5) SCEPSE OF DEVICE OF TWP CONCENTRATED SEMIUM OF INVENTION The invention relates to transport engineering, in particular to articulated vehicles, and can be used in vehicles for the mining industry, for example, in self-propelled loading and transport machines, load cranes and drilling carriages . A coupling device is known for semi-frames of an articulated vehicle, comprising horizontal and vertical hinges placed on the floor of the trailer frame and a mechanism for locking the semi-frames around the horizontal axis to be activated when carrying out lifting operations when the vehicle is stopped tl. The disadvantage of this device is low work efficiency when it is necessary to limit the rotation of the half-frames around the horizontal axis in the course of the movement of the vehicle when turning. A VEHICLE A coupling device for half-frames of an articulated vehicle is also known, which contains a vertical hinge connected to one of the half-frames and a horizontal hinge, whose axis is connected to the vertical hinge and located in the trunnion mounted on the second half-frame, and the locking mechanism of the horizontal hinge C23. A disadvantage of the known device is the design complexity and low reliability due to the occurrence of shock loads in the device. The purpose of the invention is to simplify the design and increase reliability by reducing shock loads. To achieve the goal, the horizontal hinge locking mechanism consists of a rigidly fixed on one of the half-frames and having a cylindrical part of the body with a horizontal groove in the cylindrical shaft, whose axis coincides with the axis of the vertical hinge, and two elastic horizontal

levers rigidly mounted on the second half frame on both sides of the horizontal hinge axis, while at the ends of the levers thrust conical heads extending toward the horizontal groove are arranged with horizontal hinge, the middle part of the groove in cross section is rectangular , the shapes, and the end parts are conical with a taper angle equal to the taper angle of said stop heads.

FIG. 1 shows a coupling device, side view; in fig. 2 - the same in terms of.

The device connects a half frame of 1 ton of gacha and a half frame of 2 trailers. The fingers 3 connect the vertical hinge k and the horizontal hinge 5 whose axis 6 is located in the trunnion 7. half-frames 2. The trunnion 7 is provided with tides 8 in which elastic levers 9 are rigidly fixed, and the axes of the levers 9 are located in the plane of the axis 6 of the horizontal hinge 5. Levers 9 have conical thrust heads 10c. On the half frame 1 is fixed a body 1 1, having a cylindrical part 12, in which a groove 13 is made, the end parts of which are tapered. In the groove 13, the stop heads 10 of the arms 9 are placed. The cylindrical part 12 of the housing 11 is concentric to the axis of the vertical hinge 4

The hitch works as follows.

In the course of the vehicle's forward linear motion, the half-frames 1 and 2 are located on the same line, the stop heads 10 are located in the central part of the groove 13 and allow lateral oscillations to the half-frames 1 and 2 around the axis 6 of the horizontal hinge 5. When the vehicle turns, one of the stop heads 10 moves into the tapered part of the groove 13 and thus locks the horizontal hinge 5. When rotated, the stop heads 10 interact with the supporting edges of the groove 13, the oblique conical head 10 slides along the edge of the groove 13. For turning Sheni operability slot edges 13 are performed of antifriction material, for example bronze.

The proposed design of the coupling device for half-frames of an articulated vehicle makes it possible to increase the stability of the vehicle during operation and movement in the course of its turn, and therefore makes it possible to facilitate the control of the vehicle during movement, to increase speed when turning and to increase operator safety, in addition , the dynamic loads on the parts of the device are reduced when oscillating half-frames.

invention formula
