Brake pipeline is arranged as fol 鄄
lows: compressed air produced by
air compressor 1 comes into the
main air reservoir 3 (namely wet air
reservoir); and then the air is separat
鄄
ed into two and come into the front
chamber 9 of the auxiliary air reser
鄄
voir and the rear chamber 4 of the
main air reservoir, the front chamber
9 of the auxiliary air reservoir and the
rear chamber 4 of the main air
reservoir. Compressed air in the front
chamber 9 of the auxiliary air reser
鄄
voir and the rear chamber 4 of the
main air reservoir come into upper
and lower chambers of brake valve
8, and then the air is transported
separately to rear brake chamber 12
and front brake chamber 2. Check
valves 10 installed on ends of the air
inlet pipes of the front chamber 9 of
the auxiliary air reservoir and the rear
chamber 4 of the main air reservoir in
case that compressed air in the air
reservoir flows backwards. There are
interfaces for air pressure gauge 7
and pressure -adjusting valve 6.
When air pressure reaches 0.74 -
0.84Mpa, compressed air props up
valve of the pressure -adjusting
valve, and comes into upper cover of
the air compressor to make air inlet
valve open and the air compressor
idles. When brake valve 8 is de
鄄
pressed, front and rear brake cham 鄄
ber 2 and 12 operate at the same
time, which makes front and rear
brakes operate. When the brake ped
鄄
al is released, compressed air in
front and rear brake chambers go in
鄄
to the atmosphere by front and rear
air-deflating valves 11 and 13.

Brake assembly
The function of brake is to utilize
power produced by friction between
brake drum and brake shoe slice to
absorb kinetic energy of vehicle to
decelerate or stop the vehicle. Front
and rear brakes of this brake system
adopt imbalanced structure and are mainly composed of brake chamber,
brake arm and brake
