Sector and worm of the T-150 hydraulic power steering (GUR), Kharkiv region.

Worm and steering sector of the hydraulic power steering steering wheel (power steering), wheeled tractors manufactured by KhTZ, T151k, T156, T157, T17221, T17021. The principle of operation of the hydraulic power steering, both with an axial and a rotary distributor, is based on the movement of the spool when the steering wheel is movedwheel. As it moves, it blocks one of the drain lines, and oil under pressure enters one or another (right or left) working cavity of the hydraulic cylinder. The working fluid presses on the piston with the rod, which in turn turns the wheels.The wheels turn behind it, in the direction of the movement of the spool, the body of the distributor. As soon as the steering wheel stops turning, the circuit changes. The spool stops, and the neutral position of the distributor body is restored. The liquid flows unhindered from the injection line to the drain line. Power steering withwith the help of a pump simply pumps oil through the system. The wheels are standing straight.
It should be noted that in case of failure of the hydraulic pump, control of the car is not lost.(//tractor-service.com)
