In accordance with the invention reduces the weight of the machine while maintaining the level of its protection. 4 Il.

The invention relates to the field of mobile technical means of stuck armored vehicles with traction winch and can be used in the construction of armoured recovery vehicles (BRAM), machines, technical assistance, tractors.

Known artillery tractor ATS-59 (see Average artill is an'am, mounted on the bottom of the hull in the stern machines and mechanical drive winch power takeoff from the engine. The issuance of the rope from the truck through the window of the feed sheet housing.

The disadvantage of this truck is the lack of issuance of the rope in the direction of the nose of the car.

Known floating armoured repair and recovery vehicle BREM-H (see BREHM-H, and IE, , Detva (Czechoslovakia), 1988), comprising a housing, a power winch, fixed in the front of the case, with traction reels and guide rollers. The issuance of the rope through the window in the lower front sheet body.

The disadvantage BRAM are no issue winch cable towards the rear of the machine, the complexity of the design due to the need for additional sealing of the window of the issuance of the cable located below the waterline.

Known for armoured repair and recovery vehicle BREM-1 with the issuance of the rope forward and backward (see Article 608. Technical description 608-2, Voenizdat, 1985), selected for the prototype of the proposed device, comprising a housing, a winch with rope and traction drums, mounted on Board and the bottom of the casing, a guide roller fixed in the add-CR motor.

The output branch of the rope from the top of the traction drum and stream guide roller located at an angle close to 45oto the roof of the building. The issuance of the cable towards the rear by using an additional guide roller mounted on the roof outside of the machine.

The disadvantages of the known BRAM-1 are the extra stiffness set to strengthen the roof, providing the perception of the vertical component from the efforts of the winch, and an additional guide roller for the issuance of the cable towards the rear of the machine, which increases the weight of the car, and thus reduces its mobility and maneuverability.

An object of the invention is to reduce vehicle weight while maintaining the level of its protection.

The specified technical task is achieved by the fact that in BRAM, comprising a housing, a winch with rope and traction drums mounted on the Board body, the guide roller issuance of a cable which is attached to the roof of the hull and superstructure of the roof of the building with a box of issue of the rope, according to the invention, the guide pulley and the winch is equipped with a hydraulic drive, set so that the output branch of the winch cable from the top of the traction drum and stream routing is on, and a guide roller mounted on the bracket, attached to the roof by means of a hinge, the geometric axis of which is located in the plane of symmetry of the stream of the idler.

Installation guide roller and winches with hydraulic drive so that the output branch of the rope from the top of the traction drum and stream guide roller parallel to the roof of the housing eliminates the vertical component of the efforts of the winch on the roof (to close its Board of housing). It requires no additional stiffness set to strengthen the roof, which reduces the weight of the car.

The location of the upper traction drum in the superstructure roof and fastening the guide roller on the bracket, attached to the roof by means of hinge allow you to use the same guide roller for the issuance of the winch cable back and forth.

The location of the geometrical axis of the hinge bracket in the plane of symmetry of the stream guide roller also provides direction to the efforts of the winch in the plane of the roof.

Thus, the combination of new features allows you to reduce the weight of the car while maintaining the level of its protection.

Comparative analysis of the prototype dormancy is determined so that because the output branch of the winch cable from the top of the traction drum and stream guide roller parallel to the roof of the hull, the superstructure roof is part of the upper traction drum, and a guide roller mounted on the bracket, attached to the roof by means of a hinge, the geometric axis of which is located in the plane of symmetry of the stream of the idler.

Thus, the claimed BRAM meets the criteria of the invention of "novelty."

The study of other known technical solutions in the area of study characteristics similar to the claimed solutions and leading to the achievement of a technical problem, i.e. to reduce weight BRAM while maintaining the level of protection have not been identified.

The invention is illustrated by drawings, which shows a General view of the BRAM with cuts and detachable elements (Fig. 1 - 4).

In BRAM, comprising a housing 1, a winch with 2 cable 3 and the traction drums 4, 5 mounted on the Board body 1, the guide roller 6 issue of the rope attached to the roof 7 of the hull, and superstructure 8 roof of the housing 1 with box of issue "B" cable guide roller 6 and the winch 2, provided with a hydraulic actuator 9 are set so that the output branch of the cable 3 with t Solorina part of the traction drum 4, and the guide pulley 6 mounted on the bracket 10, which is connected with the roof 7 by a hinge 11, the geometrical axis of which is located in the plane of symmetry of the stream guide roller 6.

When issuing rope 3 towards the rear of the machine arm 10 together with the roller 6 turns 180oaround the axis "C" hinge 11 (position "D").

The use of the present invention allows for a comparison with existing technical solutions to reduce vehicle weight while maintaining the level of protection and thus increase the mobility and permeability by increasing the power density.

Armoured repair and recovery vehicle, comprising a housing, a winch with rope and traction drums mounted on the Board body, the guide roller issuance of rope attached to the cover, and add-roof building with a window of delivery of the cable, characterized in that it guide pulley and the winch is equipped with a hydraulic drive, set so that the output branch of the winch cable from the top of the traction drum and stream guide roller parallel to the roof of the hull, the superstructure roof is part of the upper traction drum, and a guide roller mounted on cremerie stream of the idler.
