Hydraulic Control Assembly - Antilock Brakes: Description and Operation
HCU (Hydraulic Control Unit)
HCU (HYDRAULIC CONTROL UNIT)
DESCRIPTION
The Hydraulic Control Unit (HCU) is mounted to the CAB as part of the ICU. The HCU controls the flow of brake fluid to the brakes using a series of
valves and accumulators. A pump/motor is mounted on the HCU to supply build pressure to the brakes during an ABS stop.
OPERATION - HYDRAULIC CIRCUITS AND VALVES
The hydraulic fluid control valves control the flow of pressurized brake fluid to the wheel brakes during the different modes of ABS braking. The
following paragraphs explain how this works. For purposes of explanation only, it is assumed that only the right front wheel is experiencing antilock
braking; the following diagrams show only the right front wheel in an antilock braking operation.
