2022.3-0000010 OM 3.8.2 Service brake control of “BELARUS-1822.3/2022.3” The service brake control scheme of “BELARUS-1822.3/2022.3” is shown in figure 3.8.2.
1 – right working cylinder; 2 – right brake lever; 3, 4, 10, 13 - pipelines; 5 – left brake pedal; 6 – right brake pedal; 7 – main cylinders; 8 – left brake lever; 9 – left working cylinder; 11, 12 – flexible brake hoses. Figure 3.8.2 – Service brake control diagram of “BELARUS-1822.3/2022.3” The brakes control is intended for force transfer when braking from actuating devices (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 cylinders 1, 9 moving cylinder pistons, that influence the levers 2, 8 through the rods. The levers 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.
