The invention relates to the construction and automotive industry.

Famous test track amphibious passenger cars by application No. 2005104645 priority from 21.02.2005.

Big volume of construction works, where the track should be quite long, and in winter time a prisoner in a warm building.

The aim of the invention is to reduce the amount of construction work and earning a data capacity of movement on sinokorean on the water surface.

This goal is achieved by the fact that the built-shaped test pool, shallow pool with a two-way ramps inbound and outbound. In the pool in the automatic mode and poured on one level is supported by the water. The pool is mainly made of reinforced concrete. Along the symmetry axis of the basin the support cushion of elastic material, mimicking the curve of the front of Bambara car. Rotating roller mounted on prosinec the ends of the two thrust parallel levers attached the other ends of the drive shaft, gripped between the levers pipe with a rectangular flange that bolted for the mortgage loan the sheet at the exit ramp. On derived for all pool tubular shafts dressed pipes with rectangular flanges and shaft ends in a sump attached to the ordinary round LAF is s, and attached to them the leverage to bring them all up to the eyelets are attached to the pneumatic cylinders.

New is a cushion of elastic material made by forming the curve of the front of Bambara car, so that the rotary roller is retained on the axle by two parallel levers, fixed opposite ends to the tubular shaft, pre-dressed on the shaft another pipe between the levers, which are attached to a rectangular sheet having two rows of holes, through which the shaft is attached to the fixed sheet, laid on the axis of symmetry of the pool, his exit ramp. At the ends of the tubular shaft is installed pipe rings with attached feet with holes that are attached to the mortgage loans, the leaves on the bottom of a pit. At the ends of the tubular shaft attached disk - round flanges on which are attached the arms with the output ends of the pits, to the eyelets are attached fingers pneumatic cylinder.

Figure 1 shows the pool in the section a-a with views of the subject vehicle on the water, stubborn elastic roller;

figure 2 - the wading pool in the plan with the car and simply supported elastic roller and by means of its drive.

The test bench amphibious vehicles contains a shallow pool with 1 entry 2, field 3 ramps, vertical flanges 4, with the sides with the exit sides of the ramp 3 pits 5 and curbs 6 with two sides of the pool, including and adjacent roads with colorfully marked with the axis of symmetry of roads, ramps and the bottom of the pool. On the border with the horizontal bottom of the pool and exit ramps, car 7, down the axis of symmetry in the water, rested bambera about elastic roller 8 and under intensive rotation of all wheels of the car will rise, hanging over the bottom of the pool, creating at the same time the horizontal clamp the platen, but in the event of rising car cushion will slide down and at this time, as soon as possible to put the roller with pneumatic cylinders on the horizontal bottom of the pool. After yet accelerated the car goes forward on the ramp the front wheels, where possible breakthrough in which there is a need to slow down the rotation of the wheels.

The roller 8 is held in two parallel levers 9, which other parties attached to the tubular shaft 10. Previously between the levers on the shaft is inserted covering the pipe 11 with a rectangular foot with holes on two sides, which tube on the axis of symmetry is attached to laying the sheet on the exit ramp /not shown/. Missed in the pits the ends of the shaft 10 wear ring with the tabs and the ends of its attached round flanges, attached to the levers 12, with deduced ends of the pit, attached to the pneumatic cylinder 13.

Technical e the economic benefits of the proposed technical solutions are as follows:

- reduced the footprint of the building;

- reduced volume of construction works;

a much simplified method of testing vehicle;

- if on the test bench when all four drive wheels will raise the car on the wheels on the water, it is not necessary at least in the turning step;

and hence all the other benefits listed in other applications sambodromo the car.

Test rig for amphibious vehicles, containing a swimming pool with entry and exit ramps, side walls, road, ramp and basin borders, characterized in that the two sides of the exit ramp made the pits, put the ends of the tubular shaft, on the shaft equidistant from the axis of symmetry of the basin is attached parallel levers-brackets from sheet material and attached between the lever-mounting brackets pre-inserted on the shaft spacer tube with a rectangular foot with holes on two sides, which she attached to laying the sheet located on the symmetry axis of the exit ramp, and at the end of the lever brackets with eyes fastened on the axis of the roller, made by forming a curve corresponding to the curve of the front bumper of the car, on the ends of the shaft worn pipe ring with the tabs, which are fixed on the floors of the pits, the and the ends of the shaft fixed round flange, attached levers with llife ends of the pits, having lugs, and by the levers with two sides attached to the pneumatic cylinders.
