Main technical parameters
Structure and working principle of brake
pump
The brake pump is a gear pump and located
under cab and installed on the left power take-off
of the gearbox and tightened by stud and nut. It
is driven by engine via hydraulic torque converter
and gearbox to supply oil for brake hydraulic
system.
The gear pump works by using the meshing
movement of a pair of gears and causing volume
changes in the suction and discharge chambers.
It is the suction port with a closed volume always
in a growing state, and it is the outlet with a
closed volume always in an ever-reduced state.
Generally, the side with larger port is the suction
port, and the side with smaller port is the outlet.
