The invention relates to boats and can be used for the carriage of wheeled self-propelled vehicles, such as cars.Known self-propelled pontoons, including pontoon, tractor and semitrailer. Wheels and other equipment loaded on the pontoon, and the tractor using their cannons TRANS Such expensive and bulky device is justified for transportation by water of heavy equipment for military purposes.It is also known pontoon link (prototype), consisting of two outer and two medium pontoons pivotally interconnected, and misbelieve butt nodes located on the transom of the pontoons. At the pontoons are formed during transportation by land and disclosed using the pontoon on the water (U.S. Pat. RF N 2018561, 1994).The disadvantage of this pontoon link is the lack of a private drive and the inability to use the drive of the transported vehicle, resulting in the need to use the towing means for moving it through the water.The objective of the invention was to use an actuator of the transported vehicle to move the pontoon on the water.The problem is solved in that in the famous pontoon comprising four pontoon unit interconnected, according to the invention in two pontoon units completed wells, which are placed in the drive, made in the form of two pairs of rollers, one roller of each pair is associated with a CP propeller by means of two toothed to the, installed on two other pontoon blocks.Performing in two pontoon blocks of wells, in which the actuator is made in the form of two pairs of rollers, and the relationship of one roller of each pair with the rowing screw by means of two toothed conical pairs allows you to use the drive wheels of the transported vehicle (front or rear depending on the drive type of vehicle) for rotating propellers.The supply of the other roller of each pair of brake and connection of the brake rods with swivel pins mounted on the other two pontoon units, allows for the rotation of the non-driven wheels of the vehicle to brake one of the driving wheels, thereby stopping the rotation of the respective propeller and providing rotation of the pontoon in the right direction.The invention is illustrated by drawings.In Fig. 1 shows the pontoon assembled, longitudinal section;

Pontoon units 1 drawn to each other by means of a threaded fastening elements 4 at the ends of the fibers 2.In pontoon, designed for the transport of rear-wheel drive car, the wells 5 are executed in two aft pontoon blocks 1. In wells 5 posted actuator made in the form of two pairs of rollers 6. Back cushions 6 of each pair are connected with propellers 7 by means of two toothed conical 8 pairs. The front rollers 6 each pair is equipped with a brake 9, connected by rods 10 with swivel pins 11 mounted on the two bow pontoon blocks 1.In grooves made on the deck of the pontoon, equipped with two 12 gauge T-shaped section, the front ends of which there are holes 13 for fixing them in the racks 14, pivotally connected to the line 15 and the struts 16.Track 12 has lugs 17. For fixing the position of the vehicle on the pontoon are lanyards 18, one end of which is pinned to the lugs 17, and the other for jacking lugs 19 of the car.Along the sides of the pontoon installed inflatable elastic chamber 20. A safety cord 21 is fixed to the pontoon with the free loop the UGA on the upper trunk of a car and rely on the line 15 and the rack 14, which is fixed on the front bumper of the car. The ends of the struts 16 are secured in holding the lugs 19 of the vehicle. Blocks 1 to attach to the trunk and line 15 belts.For transportation of the vehicle on the water pontoon collected from the pontoon units 1 and slats 3, fastening their strands 2 and the fastening elements 4.The rack 14 by line 15 and the strut 16 is removed from the vehicle. The racks 14 are secured in holes 13 on the front end of each track 12, and the ends of the mowing 16 bury in the ground on the shore.The car rides on the pontoon on tracks 12 and is positioned so that its rear wheels were on the rollers 6, and the front - axle 11. Turnbuckles 18 fix the position of the vehicle on the pontoon.Along the sides of the pontoon set inflatable elastic chamber 20 and fill them with air. Then fix on the pontoon safety cord 21.Before transporting the vehicle on the water check the uniformity of the pontoon. While the stern of the pontoon must be above the bow to see 5-10For taking off the coast put the gear in reverse. Then include the forward speed. The movement of the pontoon on the water performed by the rotation of the propellers 7, driven from sappy 11 rotates together with the front wheels and through one of the rods 10 of the respective brake 9. One of the rear wheels is braked, the corresponding propeller 7 stops rotating, and the pontoon will be rotated in the desired direction.By increasing the speed of the stern of the pontoon falls, and the pontoon will glide across the water.Elastic chamber 20 serve to increase the stability of the pontoon at the wind speed and the increase of the height of the waves.Similar to the design of the pontoon, intended for the carriage front-wheel drive car. While wells placed in them a drive to the propellers are in the two bow pontoon blocks, and pins associated with the brakes, installed on two feed units of the pontoon.Thus, the invention allows for movement of the pontoon on the water drive the transported vehicle (both front-wheel and rear-wheel drive). Pontoon comprising four pontoon unit interconnected, characterized in that two pontoon units completed wells, which are placed in the drive, made in the form of two pairs of rollers driven from the driving wheels of the transported vehicle, with one roller of each pair is associated with a CP propeller by means of two toothed horses is set for the other two pontoon blocks, where the wheels turning off the steering wheel.
