Description

The utility model relates to a towing device for transport engineering and is intended for coupling a machine and trailer.

Known automatic towing device (patent for the invention of the Russian Federation No. 2156700) [1]. It has significant drawbacks, as it requires significant changes to the towing device of the existing models of automotive vehicles, changes to the drawbar structure of trailers, has a complex structure, low reliability in practical operation.

The technical task of the utility model is the automation of the coupling / uncoupling, reducing the time and facilitating the production of coupling work, as well as the reliable coupling of the machine with the trailer.

The technical problem is solved due to the fact that the semi-automatic towing device comprises a housing of an automatic coupler / uncoupling mechanism, characterized in that it further comprises a lifting mechanism housing consisting of a locking lever and a drive handle, a folding rod made of two halves connected by a hinge and installed return spring, working on unbending and resting against the stop of the folding rod, a self-release fuse and a catcher guiding the drawbar to the center of the mechanism case automatically th tractive connection / disengage.

The figure shows a semi-automatic towing device, where pos. 1 - drive handle, pos. 2 - locking lever, pos. 3 - the case of the mechanism of the automatic coupler / release, pos. 4 - return spring, pos. 5 - folding rod, pos. 6 - catcher, pos. 7 - the housing of the lifting mechanism, pos. 8 - self-release fuse, pos. 9 - emphasis folding rod, pos. 10 - drawbar, pos. 11 - hinge. The semi-automatic towing device comprises a lifting mechanism housing 7 (as an option made in the form of a metal box), in which a lifting mechanism is installed, consisting of a drive handle 1 made in the form of a metal rod with two positions “O” (uncoupling), “Z” (engagement), and the locking lever 2, made in the form of a metal plate, designed to lift the folding rod 5, made of two halves of metal cylinders interconnected by a hinge 11 and a return spring 4, emphasis with claw rod 9, made of a metal plate with a side, a self-release fuse 8, made in the form of a latch and a metal rod to prevent the folding rod from self-lifting, a catcher 6 made of two screens directed to the center of the housing 3 at an angle of 30 ° to guide the drawbar 10 trailer. Semi-automatic towing device is mounted on a regular place of the towing device and attached to the car frame.

The semi-automatic towing device works as follows: the driver aligns the semi-automatic towing device and the drawbar 10 of the trailer in one line by maneuvering the machine or by turning the drawbar 10 of the trailer before coupling the machine to the trailer, the drive handle 1 must be in position “3”, the self-release fuse 8 closed. Further, the car begins to reverse, as a result of moving the car, the drawbar 10 of the trailer slides along the catcher 6, which directs the drawbar 10 to the center of the housing 3. When the nose of the drawbar 10 touches the folding rod 5, the drawbar 10 will move deeper into the housing 3 until while the lower part of the folding rod 5, connected to the upper part of the rod by the hinge 11, leaves contact with the drawbar 10 and, under the influence of the spring 4, returns to its original state, resting against the stop of the folding rod 9, closing the semi-automatic coupler of the towing hitch with drawbar 10. When the machine is detached from the trailer, the driver switches the drive lever 1 to the “O” position - disengagement, while under the influence of the locking lever 2, the folding rod 5 is fed up, releasing the clutch with the drawbar 10. After that, the machine moves off from the trailer.

Thus, the design of this device is aimed at the possibility of automatic coupling / uncoupling and reliable grip of the machine with the trailer, reducing time and facilitating the production of coupling work.

Comparative analysis with the prototype led to the conclusion that the claimed technical solution has a simplicity of design and high reliability.
