FIGURE 3.5

Design and diagram of the hydraulic braking system

(1) hydraulic cylinder, (2) hydraulic quick coupler, (3) information decal, (4) draw back spring

Brake hydraulic cylinders (1) used in the systems are mounted on specially designed

brackets welded to the wheel axles. Oil supplied to cylinder moves the piston rod and rotates

axle expander lever. Return of cylinder to neutral position is assisted by draw back springs

(4). During normal work it does not require service. Connecting line of the brake system is

marked with decal (3).

In the pneumatic cylinders, air supplied to cylinder exerts pressure on membrane which in

turn moves cylinder piston and rotates to axle expander lever. Return of cylinder to neutral

position is assisted by draw back springs.
