The brakes control is intended for force transfer when braking from actuating de-
vices (pedals) to executing mechanisms (brake working cylinders) by means of brake fluid
supply.
The type of the service brake actuator is hydrostatic with suspended pedals.
The brake control provides independent service brake control by means of pedals 5,
6 (figure 3.8.2) and consists of two main cylinders 7, the rods of which are jointed with
brake pedals; of two working cylinders 1 and 9, connected by means of pipelines 3, 4,10,
13 and hoses 11, 12 with the main cylinders 7. The rods of working cylinders are jointed
with the levers 2, 8 of service brakes, respectively.
When pressing the pedal 5, 6 the brake fluid comes from the main cylinders 7
through the pipelines 3, 4, flexible hoses 11, 12 and pipelines 10, 13 to the working cylin-
ders 1, 9 moving cylinder pistons, that influence the levers 2, 8 through the rods. The lev-
ers turn and influence the brakes through the shafts 7 (figure 3.8.1).
Brake fluid is used in the system of hydraulic brake actuator as working fluid.
