BRAKES
Q
Partial Braking of Trailer Brake - Initiation
Piston (7) of control head (6) is pressurized through
control line
X
from the tractor service brake. Control
spool (2) is thus shifted to the left and separates from the
reservoir first brake line
B
and then bore (8). The control
spool (2) is shifted from position
c
to position
e
. The
control oil flow is blocked and hence flow control valve
(10) is switched into the regulating function in position
b
.
A constant flow
Qk
(approx. 30 L/min.) passes from port
P
to the trailer brake through restrictor (11), bore (12),
check valve (13) and port
B
.
The restrictor (11) is designed for the constant flow
Qk
. A residual flow
Qp-Qk
bypasses the flow control
valve (10), and then passes to the tractor hydraulic
through port
N
.
The pressure in the trailer brake line
B
is built up and
it acts on surface (1) of control spool (2) in opposition to
the pressure on piston (7).
