RU2705412C1 - Steering coupler unit - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: invention relates to steering control of vehicles and to couplers. Steering coupler unit comprises front and rear frames with possibility of attachment for towing vehicle and trailer. Frames are interconnected by hinge. Drive sprocket is fitted on hinge pin. At rotation sprocket, by means of chain, turns front and rear frames relative to each other perpendicular to hinge axis. Chain is passed through blocks fixed on front frame. Ends of chain are fixed on rear frame.

EFFECT: easier control and higher safety of towing vehicle and trailer coupling operation.

Description

The invention relates to the steering of vehicles, in particular, to the designs of self-propelled vehicles designed to tow sleds or similar structures, and can be used for various modifications of small-sized agricultural machinery and vehicles, including with the installation of various attachments.

Famous snowmobile towing truck Fomicheva Ruff (see certificate of the Russian Federation for utility model No. 4517, B62D 55/00, publ. July 16, 1997), consisting of a small-sized tractor with a caterpillar mover and a steering wheel with motion control elements, intended for use as a snowmobile individual vehicle.

The disadvantage of this towing snowmobile is:

- the considerable complexity and insecurity of controlling it due to the combination of the hitch-traction and the steering lever in one design, as well as the limited possibilities of its use for this reason, mainly only in winter on a slippery surface.

Known motorized towing vehicle Lebedev Vitaliy Aleksandrovich (RU) Utility Model Patent No .: 128172

The disadvantage of this towing snowmobile is:

- the control device in the form of a folding steering wheel according to the type of frame construction by a standing motor-towing truck requires skill, there is a risk of a fall.

The technical result of the claimed solution is to facilitate management, as well as the safe operation of the towbar and trailer hitch.

The specified technical result is achieved due to the fact that the steering module-hitch performing the function of the steering mechanism and the coupling device between the towing vehicle and the trailer, comprising a front and rear frame with the possibility of mounting for the towing vehicle and the trailer connected by a hinge, a drive sprocket is installed on the hinge axis, which, when rotated, by means of a chain passed through blocks that are fixed on the front frame and whose ends are fixed on the rear frame, rotates the front and rear frames relative to the other d friend perpendicular to the axis of the hinge.

FIG. 1 - device steering module coupling

FIG. 2- work

FIG. 3- turn left

FIG. 4- turn right

On Fig - 1 shows the device of the steering module-coupling, where 1 is the front frame, 2 is the rear frame, 3 is the hinge, 4 is the drive sprocket, 5, 6 are blocks, 7-chain.

The steering module-hitch operates as follows: (see Fig-2) when turning the steering wheel (steering wheel is not shown), the drive sprocket 4 to the left, which is mounted on the axis of the hinge 3, and since the sprocket 4 is engaged with chain 7, the chain 7 is hauling to the right, and then the chain that is passed through the left block 5 mounted on the front frame (in this Fig. 2 is made in the form of an asterisk) and fixed by the end to the left side of the rear frame 2, reduces the distance between the front 1 and the rear frame 2 on the left side by turning them on the axis of the hinge 3. Turn right p oiskhodit similarly.

Claims (1)

A steering module-hitch comprising a front and rear frames with the possibility of mounting for a towing vehicle and a trailer, interconnected by a hinge, characterized in that a drive sprocket is mounted on the hinge axis, which when rotating, by means of a chain passed through blocks that are mounted on the front frame , and the ends of which are fixed on the rear frame, rotates the front and rear frames relative to each other perpendicular to the axis of the hinge.
