The invention relates to vehicles, particularly to the stabilization systems of their bodies, and can be used in mining machines to improve the sustainability of their movement on the slope, comfort of movement and improved working conditions of the engine.

A device for stabilization of the body of the vehicle, containing a pair of wheels mounted on vertical shafts mounted in the supporting structure of the chassis and rigidly connected with the body (U.S. patent N 3246537, CL 74 572, 1966). A disadvantage of this device is the inability to stabilize the body, located at an angle to the horizon.

It is also known a device for stabilization of the body of the vehicle, containing a pair of coaxial wheels, each of which is mounted on a vertical shaft, drive, connected to the shafts for rotation in opposite directions, gear sectors, linking flywheels with what dostatkom of this system is the fact that that stabilizing moment only works in two dimensions and makes it possible to prevent bending of the body only in the longitudinal and transverse planes.

The purpose of the invention improve the stability of the vehicle when driving on a slope, the improvement of working conditions of the engine.

This goal is achieved by the fact that the stabilization system of the body of the vehicle, provided with a frame, engine and transmission with the master and slave shafts containing two coaxial flywheels, each of which is mounted on a vertical shaft, the actuator associated with these shafts and ensuring their rotation in opposite directions, provided with a locking device according to the invention, the flywheel shafts are hollow, located one within the other, the engine is mounted in the body, the drive shaft is located inside the shaft of the flywheel, is designed as a base body and support it on the chassis, driven shaft fixed vertically rigidly with one degree of freedom in the frame of the chassis and made the basis for reliance on him drive shaft, while driving and driven shafts articulated joint with two degrees of freedom, made in the form of a CV joint, rear wheel drive articulated TKO mounted on the chassis, the drums are arranged concentrically one within the other, each of them has an even number of fingers that are installed in the inner drum from the outside, and the marking on the inside, and put into the mesh so that each finger of the inner drum is located between the fingers of the external and the centerline of the fingers coincide with the center hinge of equal angular speeds, the locking device made in the form of cylinders arranged around the hinge of equal angular speeds between the body and chassis and mated with them by means of hinges with two degrees of freedom.

Comparative analysis with the prototype shows that the proposed system stabilization of the body of the vehicle differs in that the flywheel shafts are hollow, located one within the other, the engine is mounted in the body, the drive shaft is located inside the shaft of the flywheel, is designed as a base body and support it on the chassis, a driven shaft fixed vertically rigidly with one degree of freedom in the frame of the chassis and made the basis for reliance on him drive shaft, while driving and driven shafts articulated joint with two degrees of freedom, made in the form of a hinge of equal angular speeds the flax to the body, and the other rigidly mounted on the undercarriage, the drums are arranged concentrically one within the other, each of them has an even number of fingers that are installed in the inner drum from the outside, and the marking on the inside, and put into the mesh so that each finger of the inner drum is located between the fingers of the external and the centerline of the fingers coincide with the center hinge of equal angular speeds, the locking device made in the form of cylinders arranged around the hinge of equal angular speeds between the vehicle body and chassis part and articulated with them by means of hinges with two degrees of freedom.

Thus, the proposed device meets the criterion of "novelty". The comparison of the proposed solutions not only prototype, but also with other solutions in the art to identify their distinguishing features of the claimed solution to the prototype that allows to conclude that the criterion of "inventive step".

Stabilization of the body of the vehicle contains the same flywheels 1, 2, mounted on hollow shafts 3, 4, arranged one within the other and mounted on the control shaft 5. On the shafts 3, 4 is fixed driven gears 6, 7, which engages with a pinion 8 mounted on the shaft 9 of the drive wheels installed in the support 10. The gear 11 is also mounted on the shaft of the drive wheels 9 and is engaged with the gear 12, fixed on the shaft 13 of the motor-gear unit 14. Driven shaft 15 is fixed vertically rigidly with one degree of freedom in the bearings 16 of the frame of the chassis 17. Leading 5 and slave shafts 15 articulated between a hinge 18 with two degrees of freedom, made in the form of a hinge of equal angular speeds. When the driving shaft 5 is made base body and support it on the chassis and driven shaft 15 is made the basis for support of the drive shaft. On a driven shaft 15 fixed leading gear 19, which engages with the driven gear 20, mounted on the shaft 21 of the drive side of the gears 22, 23. Asterisks mover 26, 27 mounted on the driven shafts 28, 29 final drive. The body 30 of the articulated frame chassis CCO attached to the chassis. In the rim 33 external drum 31 is rigidly fixed to the fingers 34, the rim 35 of the inner drum 32 in bearings 36 mounted fingers 37. Fingers introduced into the mesh so that each finger of the inner drum is located between the external fingers. Each drum has an even number of toes and fingers axis intersect with the CV joint 18. The locking device consists of hydraulic cylinders 38, 39 located around the hinge of equal angular speeds between the body 30 and the frame of the chassis 17, connected by hinges with two degrees of freedom 40.

Stabilization of the body of the vehicle operates as follows. Flywheels 1, 2 have the same moments of inertia, spin with the same angular velocity but in opposite directions, by means of power take-off gear 8. In this case, since the moments of inertia and the speed of rotation of the flywheel are the same, the speed of the procession is also the same, but its direction towards each other. Thus, flywheels 1, 2 will create equally directed stabilizing moments that allow you to save the body of the vehicle its angular position in the inertial reference system at the expense of the bathing device lock. Moreover, the control device locks automatically depending on the frequency of rotation of the flywheel, i.e., the device is unlocked once the flywheel reaches the angular velocity required to create a stabilizing moment, able to hold the body, and is blocked when the fall of the angular velocity below that necessary. Torque from the engine-transmission unit 14 to the chassis is transferred to the lead 5 and the slave shafts 15. Further, through gears 19, 20 to the side of the gears 22, 23, and from them to the stars mover 26, 27. Drums are used to create a reactive moment to moment, the transferred drive shaft. The device of the drum allows the inner drum to rotate inside the external axis of the fingers. Depending on the position of the plane in either the fingers of the inner drum rotates around its axis between the fingers of external or external fingers rotate around its axis between the inner fingers, and bearings are used to reduce friction losses. When this mesh is not less than two fingers as the fingers axis intersect with the center hinge of equal angular speeds of 18. The number of planes stabilization corresponds to num the flywheels, remains in a horizontal position, and the chassis copies the terrain.

Feasibility advantage of the claimed system stabilization of the body of the vehicle in comparison with the prototype is that the locking mechanism operates in automatic mode, the increased number of planes stabilization, and therefore increases the stability of the vehicle on the slope, increases the comfort of motion and, as a consequence, improve the labor conditions. In addition, the engine runs normal to the horizontal position, which increases its resources and therefore increases the reliability of the system.
