The purpose of the invention is to increase the efficiency of the locking device by reducing wheel slippage. The goal is to ensure that a car with a locking device for adjusting the clutch of wheels containing, in sequence, a pair of control wheels on a chassis frame, a pair of wheels, fitted with a differential mechanism and placed on opposite CTODOHax chassis frames, the first device of communication of the driving wheels with the chassis frame a pair of wheels connected by an axle and placed on opposite the sides of the chassis frame with which the said axis is connected by means of a hinge with a horizontal axis. A second communication device of the non-driving wheels with a frame, a loading device placed between the chassis frame and the axis and containing a pneumatic drive of the lift placed between the last and 22 said wheels on the chassis frame, the source of gaseous compressed medium and the solenoid valve for regulating the supply of compressed medium to the pneumatic actuator, the braking devices associated with the respective driving wheels are equipped with a number of driving wheels sensor E rotational speed of the drive wheels and the comparison circuit, inputs of which are coupled to said sensors, and outputs - with braking devices and a valve solenoidnm Furthermore, the hoist is made in the form pnevmatichs Skog engine. The mentioned engine is made in bellows. FIG. 1 shows a schematic of a car with a device with a free axis, the general view; in fig. 2 shows a clutch control system attached to the device shown in FIG. 1; Fig. 3 is an embodiment of a block diagram of a comparison device; fig 4 - auto. a ball with driving wheels on a tandem axle and a device for driving wheels on a free axle, A1 tomobil 1 (represented by a powerful truck or similar vehicle with chassis frame 2) contains a pair of front wheels 3 that are controlled to adjust the movement of the car, and a pair of rear wheels wheels 4 rotated by engine 5 (FIG. 2) through differential device 6. Axial components connected to the leading wheels 4 are connected to the chassis frame by means of a lifting spring device 7. The vehicle also includes a free axis device 8, on a pair of driven wheels 9, which are rotationally connected to the shaft 10 of the free axis connected to the support 11, the front end of which is pivotally connected to the extension of the 12 chassis frame using the hinge 13. Consequently, the support can rotate in the vertical direction around the axis of the hinge 13 In order to raise or lower the bucket 1 the first wheels 9 and the free axle 10 relative to the chassis frame 2. The air motor device in the form of a pair of bellows 14 and 15 is connected between the hinge support 11 and the chassis frame 2 in order to rotate the support 11 for raising or lowering Cani 10 and wheels 9 axles with respect to the chassis frame. The pressurized fluid flows from the source 16 to the bellows elements 14 and 15 through the valve 17 to supply pressure, controlling the valve 18, the regulator 19, the two-position solenoid valve 20, the quick-release valve 21 and the branching lines of the pipeline 22 and 23 accordingly (fig, 2). With each driven wheel 4, respectively, a pair of braking devices 24 and 25 are actuated from the foot control device by brakes 26 connected between the braking devices 24 and 25 and the pressure source 16 of the fluid. A pair of speed-sensitive wheels of devices 27 and 28 are connected to each of the driven wheels, containing magnetic heads of sensors 29 and 30 for generating signal voltages applied to the input terminals; comparison circuit device 31. The two output outputs of the comparison circuit device 31 are respectively connected to the brake application devices 32 and 33 connected to the brake devices 24 and 25, and the third output output of the reference circuit device is connected to the solenoid valve 20. If the solenoid valve is in de-energized, the fluid from source 16 is compressed to the silo elements 14 and 15 through the quickly lowered valve 21 and the solenoid valve 20. The driven wheels 4 can be equipped with additional coax cial arranged wheels 34 and -35, and the axis of the driven wheels 9 can be provided with additional driven wheels 36 (FIG. 2), as the application device Brk call 32 and 33 may be any appropriate device, such as spring brake application device. The voltage signals from the speed sensors 29 and 30 are in the form of sinusoidal wave voltage signals, which are fed to the inputs of quadrature amplifiers 37 and 38, which convert sinusoidal oscillations into rectangular oscillations (Fig. 3 Then the voltage signals pass through amplifiers of pulse formers that create pulses of the same width, with the number of pulses corresponding to the speed of rotation of the respective driven wheels. 2, 4 The output terminal of each amplifier-pulse generator is connected to the input terminals of the integrator pair. amplifiers 39 and 40, which are part of a differential circuit that establishes the differential wheel speeds. Increasing DC signals are received from integrating amplifiers to the input pins of a pair of comparators 41 and 42, respectively. Each of the comparators serves as a voltage level sensor and, if a certain differential value is exceeded, triggers the corresponding output stage 43 and 44 to trigger the application of the application of the brakes 32 and 33, respectively. An adjustable voltage source 45 supplies power to the comparison circuit 31. In accordance with the invention, the solenoid valve 20 is energized simultaneously with the operation of one and the brake application devices 32 and 33. Therefore, when one of the brake application devices 32 and 33 is activated, it brakes the faster one of the slaves wheels in conditions of higher speeds, at the same time energizes the solenoid valve 20 to empty the bellows elements 14 and 15 in order to transfer the load of the car to the driving wheels 4. At bellows elements a characteristic of quick discharge and slow filling of the fluid is created. In particular, the branching diameters of the pipeline lines 22 and 23 are larger than the diameter of the rest of the pipeline device connecting the source of compressed fluid to the sylphols, the device operates as follows. In the case of a car driving on a straight line, the solenoid valve 20 is de-energized, and the fluid is compressed from source 16 to the bellows elements 14 and 15 through pressure supply valve 17, control valve 18, regulator 19, solenoid valve 20, quick-release valve 21 and branched lines 22 and 23. Car braking can be carried out by means of a brake control device 26, which simultaneously acts on braking devices 24 and 25 to simultaneously brake both groups of driving wheels 4, When the compressed fluid is supplied to the bellows elements 14 and 15, the support element rotates down to lower the axle 10 and the wheels 9 of the axis relative to the chassis frame 2, after which a certain part of the load is transferred from the leading wheels 4 to the wheels of the free axis 8i , if a car needs to make a normal turn, the speed of one group of driving wheels somewhat exceeds the speed of another group due to differential mechanism 6, but since this excess does not exceed a certain value, the circuit comparison device does not act uet, and hence, the solenoid valve 20 remains deenergized, and applying the brake devices 32 and 33 remain in the idle state. Suppose that the rotational speed of one wheel drive group 4 of the wheel 4 is greater than the rotation of the other group of driven wheels 3 (which, for example, can occur if the wheels 4 are on an icy surface, creating weak gearing). In this case, the voltage of the signal from the speed sensor 29, by a certain amount exceeds the voltage of the signal from the speed sensor 30. The output stage 43 of the comparison circuit device 31 switches to the conduction state, thereby forcing the brake application device 32 brake the faster drive wheel group 4 and 34 and energize the solenoid valve 20, after which the air and the bellows elements 14 and 15 are released into the atmosphere. Then, the axle support 11 is able to rotate upward (i.e., in the clockwise direction in FIG. 1) in order to transfer the load on the driving wheels 4. Due to the increased load on the driving wheels 4, along with braking the faster group The drive wheels 4 and 34, the drive wheels 4 and 35, are sufficiently coupled to lift the vehicle from the ice surface. If the differential of the rotational speeds between the groups of wheels of the wheels no longer exceeds a certain value, the circuit comparison device becomes inoperative, the application of the brakes 32 also does not work, and the solenoid valve 20 de-energizes, then the forces of the electron elements 14 and 15 are again compressed fluid medium to cause the transfer of part of the load of the vehicle from the wheels 4 to the wheels 9 axles. Since the diameter of the branched pipelines 22 and 23 is larger than that of the rest of the pipeline compressed fluid supply device, the refilling of the slings;) does not occur at a slower rate than the fluid from the bellows to the atmosphere when the solenoid valve 20 is under current How It can be seen from Fig. 4, the device can also be used in the vehicle 1, as a vue, the driving wheels 46 and 47 of the tandem axle, which are simultaneously driven by a known differential device of the tandem axis (not azano). In this case, the axle 8 device is automatically activated in order to transfer the load of the car to the driving wheels 46 and 47, if the rotational speed of any group of wheels exceeds the rotational speed of the opposite group, or the speed of rotation of the wheel in any group on opposite sides of the vehicle. surpasses the rotational speed of the other to thereby activate the comparison circuit device for braking the wheel in excess of the speed and simultaneously emptying the bellows devices 14 and 15 freedoms Noah axis. The invention may be applied to vehicles having pneumatic, hydraulic, electromechanical or other types of braking systems.
