Figure 1 - x-ray diagram TC, side view.

Figure 2 is a section along a-a in figure 1.

Figure 3 is a section along B-B in figure 1.

TC includes a body 1 with a longitudinal bench seat, 2 in which are located the generator-motor 3 and the movable longitudinal beam 4, the rear door 5, which contains the motor 6, the inlet 7 and the exhaust pipe 8. The shaft 9 of the generator 3 is made hollow with internal splines, the motor 6 is made with an elongated shaft 10, the end part of which is located in the shaft 9 of the generator 3, the shafts 9,10 interconnected gear sliding clutch (not shown). Beam 4 is moved along the upper 11 and lower 12 to the wheels, the axis of which is fixed to the body of the bench-seat 2 and the housing of the generator 3. The mating surfaces of the door opening 13 of the body 1 and two and 5 are tilted.

The placement of the power unit 3, 6 longitudinally of the generator 3 in the body 1, the motor 6 on the door 5 and connection shafts 9,10 using a sliding spline coupling has the following advantages:

1) evenly distributed load on the wheels, reduces tire wear and improves the controllability of the vehicle;

2) placement of units and instruments under the bench, passengers on the bench-seat, along the longitudinal axis of the vehicle reduces the moment of inertia of the vehicle, improves manageability;

3) longitudinal position of the power unit 3, 6 increases the lateral stability of the vehicle on turns by increasing or slowing the speed of the engine 6 (power unit 3, 6);

4) increases the amount of Luggage on the door;

5) large transverse dimensions of the opposed engine 6 well linked at the bottom of the door 5. In case of accident, when the rear-end collision of a car engine 6 reinforce the back of the vehicle;

6) reduces the weight of the door 5 and the effort to open and close doors 5;

7) repair of the engine 6 may be carried out on the removed door 5, a rapid replacement of the engine 6 or 5 door after the accident may be accomplished by replacing the doors 5 to another with a different engine;

8) separate wheels with covers-fairing provide the best protection of the body during a side collision.

The upper part of the beam 4 has a cross section of lock is UTY triangular profile, the challenge at the bottom of the dome. Beam 4 is moved along the upper wheels 11 mounted on the body of the bench-seat 2, and the lower wheels 12 mounted on the body of the generator 3. The ledge 14 of the beam 4 limits the amount of opening of the door 5. For people with disabilities, by transferring the ledge 14 of the beam 4, it is possible to provide a greater amount of opening of the door 5 to the entrance of the stroller to the doorway 13. When the door is open 5 beam 4 protects passengers from contact with the shaft 10 of the engine 6. The inner space of the triangular profile of the beam 4 may be used for placement of cables and pipelines and control for supply of hot air from the engine 6 for heating benches-seats 2 and heating of the cabin.

The rear part of the beam 4 has a flange and rigidly connected to the flange and the motor housing 6.

The air intake and the exhaust of the engine 6 is on the roof of the vehicle. Provides the power of the engine 6 clean air and the exhaust of spent gases high into the air, which reduces its harmful effects.

The mating surfaces of the door opening 13 of the body 1 and the door 5 is located at an acute angle to the longitudinal axis of the body 1, and the places of intersection of the opposite surfaces of the opening 13 are located behind the door opening 13. In an accident, lateral and angular beats on the door 5, the load is transferred to the nearest site is Reema 13 of the body 1, this reduces the displacement of the door 5, reduces the load and displacement of the beams 4, increases the reliability of the power unit 3, 6. Closing doors 5 occurs with less noise.

The vehicle has a hybrid powerplant. Operating in economy mode, the motor 6 rotates the generator 3. At stops when opening and closing door 5 to reduce friction in the spline coupling the motor 6 can be stopped or run at low speed with no load.

In the area of the buffer zone of the surface 15 of the door 5 is made convex, with constant or variable radius of curvature and covered with a thin layer of polymer with a low coefficient of friction. In case of accident, when the rear-end collision the front buffer netaudio car will slide along the inclined convex surface 15 of the door 5 by lifting the rear of the vehicle and quenching kick. Acting as a buffer, the convex part 15 of the door 5 does not increase the size of the vehicle.

Accommodation on the door 5 opposed engine 6 reduces the height of the center of gravity of the vehicle increases its stability. The engine 6 is harmoniously linked at the bottom of the door 5, when the rear-end collision of the vehicle passenger car increases the resistance of the convex part 15 of the door 5.

If the rear door 5 holes, Windows, adjacent to the rear end of the shaft 10 of the engine 6, the possible cranking and starting of the engine 6 manual actuator mounted guns and stationary and is of Regatul.

Longitudinal position of the bench-seat 2 defines the original transport position passengers (and the driver). When traveling close fit allows an increase in the number of passengers. Body width (TC) is small, the driver (and passengers) is located in the middle of the body 1, browse back through the exterior mirrors are equally convenient. The body shop-seats 2 performs the function of the spinal hollow frame in which it is possible to place instruments and units.

Equidistant from the sides of the location of the bench-seat 2 allows, if necessary, to get two full beds, by assigning a special piece of cloth between the sides of the body 1, supported in the middle on the cushion of the bench-seat 2.

The invention improves the load distribution on the wheels, provides a more uniform tire wear, improves cornering stability and controllability of the vehicle, reduces the force required for opening and closing door 5.

The method of transformation of the directional mechanical oscillations into the unidirectional discontinuous translational movement provides for interaction among themselves of two masses of the system, one of which is the inertial mass rotating about its axis and simultaneously is moving in respect to the other mass along the elliptical trajectory with its resilient contraction to the running track of the ellipse providing the system with the directional mechanical oscillations. The used system is unbalanced with the center of masses coinciding in the static condition with the center of gravity of this system and with one of the ellipse focal points. The movement of the system is exercised by the successive step relocations in the moments of the impulse action of the inertial forces along the long axis of the ellipse of the maximal value disturbing force directed from the main focus point in the movement direction. The method of the controlled movement of the transport vehicle in the preset direction provides for utilization for production of the tractive effort of the propeller generating impulses of the inertial forces. The device for production the directional mechanical oscillations contains: the body with the running track of the elliptical form, the inertial element capable of running around the elliptical running track and rotation about its axis, the driving mechanism. The propeller of the transport vehicle contains: the device for production of the directional mechanical oscillations coupled by the driving mechanism with the propeller.
