Due to the lack of effective hydrostatic pumps and motors modern vehicles moving mechanical transmission containing the coupling boxes PE is taking into account the effective efficiency of internal combustion engines, equale= 0,35).

Known mechanical transmission transport [East. 1, page 13], which contains the clutch, gearbox, cardan transmission, main transmission and differential, placed in the hollow beam rear axle.

The disadvantages are:

the design is very complex, not efficient - effective efficiency with an engine (internal combustion engine) is 0.1-0.2, the operation noise, wears out and breaks. Manual transmission will not work without the main brake system.

Hydrostatic transmission (GOTH - prototype) containing a hydraulic pump with a sloped block [East. 2, page 59, Fig. 17] directly connected to the engine shaft, the motor wheels [East. 2, page 100, Fig. 42B].

The disadvantages are:

- the hydraulic pump is very complex structures, made of cylinder interacting with the buckets (the number of buckets 7 with a very limited volume of the cylinder) with limited performance with a considerable mass, with low efficiency = 0,83 - 0,85 [East. 2, page 37];

the hydraulic motor is very complex, made with six or more buckets [East. 2, page 82, Fig. 30, 31] with a mass of 77.5 - 545, 408 kg on one wheel [East. 2, page 96, Fig. 40, PL. 7]. The overall efficiency of the pump-motor [East. 2, page 57]total= 0,63. With the remains of a GOTH on any mass-produced car is not used [East. 2, page 11].

The invention consists in that the hydrostatic transmission of transport contains a volumetric pump, the shaft of which is connected to the shaft of the engine (internal combustion engine), volumetric motors, the shafts of which are connected with the axes of the wheels, the discharge pipe of the pump is connected to the pressure lines, according to the invention the hydraulic pump is made rotary positive displacement, the suction nozzle which is connected with the cavity of the tubular frame, and a discharge pipe connected to the hydraulic accumulator, hydraulic motors made surround the rotor and each axle of the wheel is connected to their shafts.

According to the invention the discharge line connects the rotary positive displacement pump with a liquid battery that is connected to the main liquid pipelines with valves connecting them with volumetric rotary motors.

Hydrostatic transmission transport contains volumetric pump (hydraulic motor), the rotor which interacts with the inner surface of the housing and is made of cylindrical shape, according to the invention for simultaneous closing holes of the suction and discharge nozzles on the surface of the rotor has a sector Oab" arc "ab" angle , ,BR>R1= R - e.

In Fig. 1 shows the transport (without cab and body).

In Fig. 2 is a cross section of a rotary positive displacement hydraulic pump-motor.

In Fig. 2a depicts Playground abc on the surface of the rotor.

In Fig. 3 is a cross-section of the rotor when the shaft rotates counterclockwise.

In Fig. 4 is a cross-section of the rotor when the shaft rotates clockwise.

In Fig. 5 is a schematical diagram, when the transport is moving forward.

In Fig. 6 is a schematic depiction when the transport is moving back.

Hydrostatic transmission transport (Fig. 1, 2, 2A, 3, 4, 5, 6), containing the engine 1 (patents N 1807219, N 2016246 or internal combustion engine - an internal combustion engine). In Fig. 2, 3, 4 shows a cross-sectional view of the rotary engine operating modes of the hydraulic pump, the hydraulic motor with the most high, effective indicators (set out above). The engine 1 comprises a cylindrical housing 2, a shaft 3 which is mounted the rotor 4. To balance the centrifugal force of the rotor 4 through the wall of the shaft 3 is set to the second rotor 4' is rotated 180o(of Fig. 2 shows a dotted line details, see patent N 1807219), resulting in power and proizvoditelnosti of 8 PCs nelimousine details.

Due to the fact that the design of each of the rotor sections are identical, the numbers show the details of one section.

Further, the transmission includes a valve 5, the nozzles 6, 7, Crescent-shaped working chamber 8 (the coincidence of the axis 0 of the housing 2 with the axis 0' of the rotor 4, Crescent-shaped working chamber 8 is transformed into a ring with thickness h (Fig. 3) inner radius r, and 5 valve chamber 8 divides in half.

To the nozzles 6, 7 to perform without valves, the sector Oab (Fig. 2) from the corner arc "ab" is performed with radius R' is the length that is less than the thickness of the gap "e" than the radius of the inner shell 2 of the engine 1 or R - e = R'.

Playground abcd (Fig. 2A, sector Oab - Fig. 2) simultaneously closes the openings of branch pipe 6, 7, therefore, the angle < sector Oab, the length of the arc ab 3-4ogreater than the angle < sector Oa'b' (Fig. 3) - at the walls of the pipes 6, 7 is more O less ab 3-4o.

The area abcd are grooves for installation of seals 9 (Fig. 2A), and at the ends of the rotor 4 are ring seals 9' (Fig. 2).

The shaft 3 is connected with volumetric rotary pump 10 discharge line 11, provided with a valve 12 (the cross). The valve will run as bone accumulator 13.

Volumetric rotary hydraulic motors 14, 15 (Fig. 2, 3, 4 are transverse sections), and in the diagrams (Fig. 5, 6) is shown - each section slices [as in the East. 2, page 100, Fig. 42B]. Each section of the motor has two branch pipe 6, 7 (one injection, another exhaust). The shaft 3 of the motor 14 is connected with the axle 16 mounted inside the hollow beams 17 and the shaft 3 of the motor 15 is connected with the axle 18 mounted inside the hollow beams 19. The axle 16 is connected with the sprocket wheel 20 and the axle 18 with a sprocket wheel 21.

For traffic ahead (Fig. 1, 5) discharge pipe of the hydraulic motors 14, 15 are connected by a line 22 with valve 23 (x), exhaust pipes hydraulic motors are connected to line 24 and valve 25 (x), which is connected with the tubular frame 26 to which is connected line 27 of the hydraulic pump 10 with a latch (cross) 28.

For traffic back (Fig. 1, 6) discharge pipe of the hydraulic motors 14, 15 are connected by a line 29 to a valve 30 (x), exhaust pipes hydraulic motors are connected by a line 31 to the valve 32 (x) and with a fully tubular frame 26.

The front part of the tubular frame 26 rests on the beam of the front wheels 20', 21'.

When performing TRANS, orapki transmission, drive shafts, main gear, and there is no need the main brake system [East. 1, page 293], except for the Parking brake.

Still will not pump oil lubrication system, as it is the function of the liquid accumulator 13.

For traffic starts engine 1 to which through pipe 6 (Fig. 4) in the working chamber 8 is injected.with. N 1820010), heated to 300oC water, the water having a pressure of 180 atmospheres, served in a hot working chamber 8, faster combustion of the working mixture in internal combustion engines, becoming superheated steam (at the same time absorbing heat engine, i.e., cooling), rotates the rotor 4 is made with an o-ring seal 9. The shaft 3 of the hydraulic pump 10 is rotated clockwise (Fig. 4, the arrow with the letter W). Thus the fluid from the cavity of the tubular frame 26, line 27, valve 28, fills the working chamber 8 (Fig. 3) inside the housing 2, separated by a valve 5, and the liquid outside of space "bd" performed by seals 9 (Fig. 2A), through the pipe 6, line 11 and valve 12 fills the accumulator 14.

When pumping liquid in the accumulator 13, the engine (ice) powered by the economical regimen fuel (180 g/l C. h) and the lowest emission of harmful gases (twice).

As soon as the driver opens the valve 23 (x), fluid under pressure from the hydraulic accumulator 13 through the line 22 is supplied to the hydraulic motors 14, 15, getting into the working chamber 8, and begins to rotate the shaft 3 of the rotor 4 and through the shafts 16, 18, placed in the hollow beams 17, 19, will start to rotate the drive wheels 20, 21, (20oand 21'), moving transport forward (Fig. 5, the arrow with the letter V). The spent fluid through the pipe 7, valve 25, line 24 is poured into the cavity of the tubular frame 26.

For transport links close valves 23, 25 routes 22, 24, and the fluid in the working chambers 8 stops moving because it is not compressed, consequently, the wheels 20, 21 (20' and 21') ceases to rotate, and they move. The valve should be closed slowly, leaving a gap in them. When a sufficient reduction in the rate of transport of the valve fully closed, and the transport will stop.

The Parking brake is required for repairs and replacement fluid.

For traffic back valves 23, 25 remain closed and valves 30, 32 highway 29, 31 are opened, the valve 30 is regulated by the speed of movement, given that the speed is the same as when moving forward.
