Description

(54 COUPLER DEVICE FOR SEMIUM OF JOINTED VEHICLE

one

This invention relates to a transport engineering, in particular to articulated vehicles.

The closest solution of the known ones is a coupling device for semi-frames of an articulated vehicle, containing a vertical hinge consisting of eyelets fixed on the first half-frame and forks fixed on the second half-frame with eyelets covering the said first half-frame eyes, while the contacting eyes. vertical fingers, mounted / on a traverse yoke and hinged at one end on the first half of the frame. Hydrocyl Indra steering with hydraulic lock, the other to They are pivotally connected to crosshead 1.

The disadvantage of the device is a rigid connection of the half-frames of the vehicle in the horizontal plane during its towing in the absence of supply from the pump of hydraulic fluid to the steering system, excluding the possibility of its folding in the horizontal plane.

The purpose of the invention is to reduce the complexity of towing a faulty vehicle.

To achieve the goal, the traverse is fastened to the fork by means of a removable additional finger and is pivotally connected to one of the said vertical fingers.

FIG. 1 shows the proposed device, side view; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. 2

A device for connecting semi-frames 1 ton of gacha with semi-frame 2 semi-trailer contains a vertical hinge, made in 15 kind of plug 3 with male lugs 4, each of which is connected by fingers 5 with female lugs 6. Fork 3 is fixed on the semi-frame 2 of semi-trailer, and the surrounding semi-trailer 6 - on the half frame 1 ton gacha. A fork 8 is fixed to a fork 3 by means of a detachable pin 7, which is connected with a half frame of 1 ton of gacha through a vertical hinge pin 5 and hydraulic steering cylinders 9 with hydraulic locks (not shown). The device works as follows. In the working position, when the half-frames are folded, the hydraulic cylinders 9 of the steering act on the half-frames 1 and 2 through the yoke 8 fixed relative to the axis of the vertical hinge with a finger 5, and relative to the half-frame 2 of the semi-trailer - with a removable finger 7. To enable towing (in the cases mentioned above ) it is enough to extend the removable pin 7 so that the half frame system 1 ton of the gach - half frame 2 semi-trailer gets freedom of movement by disconnecting it from the rigid system, which is created by the yoke 8 and locked with hydraulic locks, the guide steering cylinders 9. This allows the half-frames to fold about the axis of the vertical joint, which is necessary when towing hinged articulated vehicles. The application of the proposed coupling reduces the labor and time costs of the machinist to the preparatory and final operations when towing an articulated articulated vehicle from 4 h of the work shift to 0.15 h (in monetary terms, respectively, 5.2-0.2 p) for one case of towing, that for the annual release program of coupling devices (200 pieces) is 770 hours or 1000 p. Invention Coupling device for semi-frames of an articulated vehicle containing a vertical joint consisting of eyes fixed on the first half-frame and fixed on the second half with eyelets covering the specified first-frame eyes, while contacting the half-frames of both half-frames are connected with vertical fingers mounted on the forks. traverse and hinged one ends on the first half frame hydraulic steering cylinders with hydraulic locks, the other ends of which are hinged a crosspiece, characterized in that, in order to reduce complexity of faulty towing vehicle, the traverse is fixed on the plug by removable additional pin and pivotally associated with one of said vertical fingers.
