company driven wheels, vertical; And traction loads.

A: The figure shows a vehicle's transmission scheme, including the proposed drive. I The transmission contains a pump 1, whose shaft I is kinematically connected with 1 secondary shaft 2 transmissions. Case 3 is a pump and is connected by a coupling 4 of the switching mechanism and gear 5 to gear 6 or 7. Sixth gear is connected to the cross-axle differential 8 of the front axle. Gear 7 is fixed in the transmission housing 9. On the body 3 of the pump 25

a device 10 is installed for: discharging liquid from a rotating pump distributor. The device 10 is installed in the transmission housing 9 and the trunk is connected to the spool 11 .. The latter has three positions, with ONE of which the throttle 12 is connected to the trunk of the device 10, with the other to the other highway, and with the third throttle 12 from the device 10 and the connection to the latter of the pipeline 13 for draining the working fluid to the active organs of the machine gun. There is a vehicle speed sensor made in the form of a mechanical centrifugal sensor consisting of levers T4, weights 15, tons g 16, movable clutch 17 and springs 18. At the same time movable clutch 17 is connected to the core 19 of electromagnet 20 fixedly mounted. Levers 14 are connected to a front axle drive cardan shaft 21. In addition, the movable clutch 17 by means of the lever p 22 and the ty gi 23 is connected with the device for adjusting the throughput of the throttle 12.

In addition, on the rear axle 24 of a wheeled vehicle, in the coupling device, hook load sensors 25 are installed, and on the front axle 26, vertical load sensors 27 and a sensor 28 are mounted

In the front axle mode, body 3 is connected by clutch 4 to gear 6 of the wheel-to-wheel differential 8. Spool 11 is installed in the first or second position, depending on the forward or reverse travel of the machine. When moving at low speed, the centrifugal force of the weights 15 is small, due to 3Tort) the clutch 17 of the regulator is in the lowest position, keeping the throttle 12 in a state of some minimum capacity. This minimum flow capacity of the throttles, together with the low capacity of the pump 1, determines a certain amount of pressure in the pump AND, respectively, an incomplete amount of torque transmitted to the front axle.

As the speed of the vehicle increases, the performance of pump 1 increases in proportion to the speed. However, the amount of torque transmitted to the front axle does not increase. This happens because with increasing machine speed, the centrifugal force of the weights 15 increases, which disperse to the sides and, compressing the spring 18, move the pu 23, increasing the throughput of the throttle 12. By appropriately selecting the lengths of the arms and the speed sensor and The throttle can provide a change in throttle ability, identical to the change in the performance of pump 1, as a result of which the torque on the front axle wheels does not depend on the speed of movement.

In addition, it is obvious that with a curvilinear movement of a vehicle with a hook load and a front linkage, the torque value on the front axle wheels should differ from the torque values when it is idling. The indicated values in the process of work are changed, which is necessary.

A bridge for adjusting the torque on the wheels of the front axle. In this case, sensors 25, 27 and 28 produce signals proportional to the values of the hook load, front axle load and the steering angle of the wheels to be controlled. The signals are amplified by amplifiers 29, 30, and 31 and fed to an adder 32, and then to a block filter 33, where the total signal is smoothed (without dynamic casts) and fed to an electromagnet 20. Under the influence of an electromagnetic field induced by an electromagnet 20 coil The core 19 is drawn into the coil of the electromagnet 20. In this case, the movable coupling 17 connected to the core 19 moves the lever 22 and the pull 23 connected to the throttle 12. And the throttle, in turn, is set to a certain position, which corresponds to some pressure of the pump 1, and, accordingly, a certain amount of torque on the front axle wheels with a value of 1

cue hook load, load on front axle and angle of turn of controlled wheels.
