FIG. 1 has a locomotive with a device for load balancing; in fig. 2 - the same. plan; in fig. 3 - switch.

The device contains irodol nanravlyuschy 2 mounted on frame 1, in which ballast masses 3 are installed.

field windings on parallel - with e, item 32.

The interlocks from the contacts 36-39 of the reverse engine of the traction motors are installed on the frame of the reverser. Each pair of 36, 37, and 38, 39 contacts of these interlocks is connected to the field of the excitation windings to change the direction of the enemy cortex of the engines 4 when the direction of movement of the locomotive changes.

The pins 35, 40, 41, 42 are placed in traverse holders (not shown) fixed on the housing 9 and are included in the circuit of the power source (for example, a control generator). In the cpeflHeivi position of the sleeve 20, the contacts 35, 40-42 are aligned with the ring 34, and in the extreme positions of the sleeve 20, with the contact elements.

In order to clearly set the masses 3 to the initial position, following the locomotive ia has run out (there is no current in the traction motors) on frame 1, in the zone of the middle cross section of masses 3, their initial position, the drive has a blockage, contacts 43 of which are included in the stump of the electric coils - move | Ateli 4.

The device for leveling the loads on the KO,: iecHb e bunks of the locomotive works as follows.

There are no currents in the ibi6e a mode following the locomotive in the power circuit of the traction engines. The tangent force of a locomotive is zero. The reaction force from the sos-nov through the coupler to the loco is zero. The LA moment of forces, the change of the Y-1Y static distribution of loads on the COP ;,; 1mokmotiva, is equal to nu.yu. Ballast e mass 3 decayed on average, the original ns. souting. The contact of the change mechanism is open.

 14 non-switch 9 de-energizes i .. In chambers 11 and 12, atmospheric pressure). Node force springs 25 aperture K), 1lunger 18 and sleeve 20 are in the original (middle) position. K:) 1 pins 35, 40-42 are mounted on the ring insulator 34. There is no voltage at the terminals of the electric motors 4. One pair of (Ch1tact () in 36, 38 reverse engines of traction motors is closed, and the other lapa 37, 39 is open.

With the transition of the work of the locomotive in the mode of t and m, the motors are loaded and a current appears in these imp1. A tangle is created. The power of the hypokum motif is generated as a function of the motor current.

From its appearance, a force pair arises, unloading the front (in the direction of travel) and additionally loading the rear wheels of the locomotive.

In coil 14, switch 9, including 4 (iiK) ii, also has 13 currents in the motor circuit. Magnetic flux is created in the magnetic core 13. Anchor 15 is moved to the right (as shown). The diaphragm 10 connected to the core 15 is mixed to the right and together with it the plunger 18 and the sleeve 20 move to the right. Contacts 35, 40-42 are aligned with the contact elements 26, 27, 30, 31. The electric circuits of the electric motors 4 are formed and their cores start rotate. As a result, the movement mechanism shifts the ballast masses 3 in the direction of the first driver’s cabin.

When the plunger 18 is displaced to the right (according to the scheme), the channel 21 is aligned with the hole 22 and the compressed air passes through the calibrated section of the channel 21 into the chamber 12. The pressure in the chamber 12 increases and the diaphragm 10 begins to shift to the left (according to the diagram). When the pressure of the compressed air in the chamber 12 reaches the value of the electromagnetic force acting on the measles 15, the diaphragm 10 together with the plunger 18 and the sleeve 20 returns to the middle position, and the contacts 35, 40-42 are displaced to the ring insulator 34. The motor circuit 4 opens. The ballast masses 3 are displaced from their average position in the direction of the first cabin of the Mapuinist and are stopped in the application, at which a regenerating moment appears that compensates for the effect of the moment.

When the load is removed from the traction motors (transition from traction to the coasting mode), the current in the chains of these machines disappears. Coil 14 is de-energized. By the pressure of the compressed air of the chamber 12, the diaphragm K) bends to the left, and together with it the plunger 18 and the sleeve 20 are displaced in the same direction. In this position, two electrical circuits are formed with the winding of the core and the driving of the electric motors 4 for rotation in the opposite direction drives the mass 3 in the direction of the initial position.

When the plunger 18 is displaced to the left from the middle position, the air from the chamber 12 through the channel 24 is exhausted and the atmosphere - the air pressure in the chamber 12 decreases.

The diaphragm 10 returns to its original position. At the same time, the plunger 18 and the sleeve 20 are moved to the middle position. After the masses 3 are set to the middle position, the contact 43 opens. The circuits of the electric motors 4 are de-energized and the movement mechanism stops. The diaphragm 10 is held in the middle position by the springs 25.

When the direction of movement of the locomotive is changed, the second driver's cab becomes head in the course of the movement. The reverser is shifted to the second position. The contacts 36, 38 of the reverser interlocks are open, and the contacts 37, 39 are closed. Due to these switchings, the direction of rotation of the cores of the electric motors 4 and, accordingly, HanjiaB is changed. IeHne movement of ballast masses 3. All other operations of apparatus 9 and movement of the movement proceed in the same order as that described for the variant of moving the locomotive by the first cab forward.
