The rigid coupling of the towing vehicle with the towed object

 

(57) Abstract:

The invention relates to vehicles, and more specifically to the mechanical coupling devices for connecting tractors and towed objects without departing crew of the tractor in the conditions of warfare. The device ill hitch of the towing vehicle with the object is mounted on a tank truck and includes a tow bar, made in the form of tubes with eyelets at the ends, earrings for connecting the rods to the object, the opener and chain suspension. the implement hitch of the tractor with the object through the hard grips with the leading (or slave) the wheels of the object significantly reduces the requirements for precision maneuvering of the tractor. The presence of side constraints ensures centering of the body of the tractor in relation to the body of the object, and together with supports they provide hit hard grippers into engagement with the leading (driven) wheels of the object. The movable rods with hard hooks can significantly simplify the process of coupling the Prime mover with the object and execute it without release of the crew of the tractor, thus ensuring the safety of the personnel of repair and emergency authorities, 2 Il.

The invention relates to transport the ez release of the crew of the tractor in the conditions of warfare.

A device for coupling an armoured repair and recovery vehicle with brontobytes. Such a device has a manipulator in the form of a telescopic crane boom, rod, lever capture and tow rope (see ed. St. N 258008, class B 60 D 1/10). The design of the device allows the connection of the armored repair and recovery vehicle with steerable towed object using tow cables. When using this device coupling the Prime mover can be made only with the managed object.

It is also known device cruel hitch of a tractor with a tank containing the opener, chain suspension and towing rod, made in the form of a pipe with lugs on the ends and earrings (see Manual evacuation of armoured vehicles. M Voenizdat, 1981, S. 75-77, Fig. 90-93). The design of the device allows the coupler with unmanaged evacuated tank two tow bars and two eyelets for attaching the tow bars with the release of the crew of the car. To facilitate installation of the hard rods at the hitch of the tractor with unmanaged tank used chain pendant. This device technical essence and essential features is the closest to the claimed and accepted for who go only with the release of the crew of the car.

The present invention is the provision of compounds of the tractor with towed object with no crew access from the car.

This object is achieved in that the towing rod, pivotally connected by one end with the tractor, are movable with hard hooks on the free ends and can be rotated in a horizontal plane through the working cylinders, and aft of the tractor mounted side stops stops.

In Fig. 1 and 2 shows a General view of the device rigid hitch of a tractor with a tank and mark: 1 tractor; 2 movable rod; 3 working cylinder; 4 stop; 5 lateral stop; 6 drive wheel; 7 - hard grip; 8 of the towed object.

The device is rigid hitch tractor with towed object works as follows. Before evacuation mechanic-truck driver hops in the opposite sides of the movable rod 2 by means of working cylinders 3, including the related hydraulic system. Then the tractor 1 pulls back to the object 8, intending to escape. The relative position of the tractor 1 with respect to the towed object 8 is provided by the maneuvering of the tractor so that the side is terminated. The inclusion of the hydraulic system are working cylinders 3, which drive the movable rod 2, hard grips 7 which capture rims wheels 6 of the object 1. Observation while maneuvering the tractor mechanic-driver carries through or panoramic rear view mirrors, or periscopic observation devices. Coupling of cars produced, then do the towing.

The movable rods with cruel clamps can significantly simplify the process of coupling the Prime mover with the object and run it with no crew access. The implement hitch of the tractor through the hard grips with the leading (or slave) the wheels of the object significantly reduces the requirements for precision maneuvering of the tractor. The presence of side constraints ensures centering of the body of the tractor in relation to the body of the object, and together with supports they provide hit hard grippers into engagement with the leading (driven) wheels of the object.

The rigid coupling of the towing vehicle with the towed object containing pivotally connected by one end with the tractor tow bar, made with hard hooks on the free ends and can be rotated in a horizontal plane, otlichayushiesya of the towed object, and the rotation of the tow bars by means of hydraulic cylinders.

Coupler for trailer // 2342258

FIELD: transport.

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.

FIELD: trainer engineering.

SUBSTANCE: the device contains the object of evacuation with a tow gear and a traction engine with a manipulator controlled from the traction engine, the object being fixed on the ground. The tow gears are fixed on the object with the possibility of changing their position relative to the ground. The manipulator has a lever with a detent device for placing the towline with a yoke. The detent device, in its lower part, has a through longitudinal slot, the width of which is larger than the diameter of the towline but smaller than that of the yoke. The towline is fixed on the traction engine so that it can be removed from the traction engine after connecting to the tow gear of the object.

EFFECT: time and cost saving, increased driver training safety.

FIELD: transportation.

SUBSTANCE: towing devices are fastened on object with possibility to change their position relative to ground, towing cable is fastened on tow-car with possibility of its disconnection by tow-car moving, towing devices of tow-car and evacuation object are connected inside the tow-car and cable is disconnected from the tow-car by the tow-car moving.

EFFECT: time and cost reduction and improvement of tow-car drivers training safety.

FIELD: transport.

SUBSTANCE: proposed method of retrieving vehicle with the help of retriever comprises connecting first end of tow rope with retriever towing hook or the first end of second tow rope with retriever winch rope. Manipulator controlled from inside the retriever accommodates parts of tor ropes. Then retriever is moved towards vehicle to be retrieved, second end of the first or second tor rope is jointed to vehicle towing hook by manipulator lever. Retriever tensions appropriate tow rope and the latter is uncoupled from manipulator and its lever. Now vehicle is towed or retrieved. Central part of every tow rope is arranged to allow adjustment of friction and elastic forces. Electrode is arranged in retriever body on the first tow rope or on winch rope and electrically connected with retriever inside frame. Emergent release from retrieved vehicle is made by cutting appropriate rope with the help of electrode. Proposed device comprises two tow ropes connected with retriever, one connected with towing winch, and manipulator with lever control from inside the vehicle. A part of every tow rope is secured in bracket by friction and elastic forces.

EFFECT: higher reliability and safety.
