Device for towing vehicles
(57) Abstract:Usage: applies to vehicles, in particular to towing devices for trucks. The inventive to the frame 2 of the tractor by means of detachable connectors are attached vertically arranged plate 4. Plate 4 is placed symmetrically with respect to the traction hook 1. With the plates 4 are rigidly connected horizontally positioned plate 3. Plate 3 are arranged on both sides of the hook 1. In the plates 3 are vertical holes, in which the flexible rod. 2 Il. The invention relates to vehicles, particularly to a towing devices trucks.The purpose of the invention provide the possibility of regulating the rotation angle of the steered wheels of the towed vehicle.In Fig. 1 shows the proposed device, side view, Fig. 2 is a top view.Traction hook 1 is mounted on the frame 2 of the tractor. Located on both sides of the traction hook 1 is horizontally placed plate 3 rigidly attached to a vertically positioned plates 4. Plate 4 attached to the frame 2 of the tractor by means of detachable connectors and posted imagestate with vertically spaced plates 4. In the plates 3 are vertical holes 5, each of which has the ability to interact with skipped through it a flexible shaft fixation in which the hole is carried out by means of the finger 6.This device allows you to adjust the rotation angle of the steered wheels of the towed vehicle by means of holes 5, through which the flexible rod. A DEVICE FOR TOWING a VEHICLE that contains a hard pull, hinge mounted with their ends on the towing vehicle and on a towed vehicle, flexible rod, mounted by one end on the carrier on opposite sides of its longitudinal axis and the other on the cross levers steering of the towed vehicle, and rigidly mounted on the towed vehicle along its longitudinal axis bracket with blocks, through which zapasovany flexible rod, the middle parts of which are connected by springs, characterized in that, to ensure the possibility of regulating the rotation angle of the steered wheels of the towed vehicle, to the frame of the tractor by means of detachable connectors symmetrically vertical axis is attached to the two vertical spaced blsany with the corresponding vertical slabs of ribs, moreover, in a horizontal plates made of vertically spaced holes, each of which has the ability to interact with skipped through it a flexible shaft fixation in which the hole is carried out by means of a finger.
SUBSTANCE: coupler contains means for installation on trailer with capability of pivot-hinged turn of at least one left wheel and at least one right wheel, independent means of pivot-hinged turn of trailer and prime mover coupling, means for performing differential turn of wheels and trailer with regard to prime mover in process of turn performed by prime mover. Limiting device is made so as to limit magnitude of wheel turn as compared with wheel turn related to trailer in absence of limiting device. Limiting device contains follower with front end connected with said devices for installation of wheels on trailer and rear end. Follower includes protruding coupling sphere on rear end or near it. Limiting device additionally includes slider guide made so as to couple with prime mover and installed in parallel with or inclined to prime mover and trailer chassis. Coupling sphere is installed with ability to move along slider guide of limiting device in process of prime mover movement.
EFFECT: securing of smooth and safe turning and exclusion of folding effect.
