(F) Dynamic Brake Operating
When releasing the pedal (1), the regulator valve (2) forces the servo piston (4) to the neutral position. The pump
variable swashplate (19) also goes back to the neutral position.
Still the machine tends to keep running by inertia force, but no oil is pressure-fed because the pump variable
swashplate (19) is in the neutral position. (There is no oil flow from the HST pump.)
The output shaft (16), however, is rotated in the same direction as before releasing the pedal (1).
Now the stationary motor (13) works like a pump to suck the oil from port
D
and pressure-feed it from port
C
.
The oil coming from port
C
pushing open the high pressure relief valve (12) and flows through the check valve
(10) back to port
D
.
The dynamic brake force is determined by the force that is exerted to push open the backward travel
high-pressure relief valve (12).
When the dynamic brake is applied, the pressure at port
D
drops below the charge pressure level. If the oil from
port
C
is not enough to make up for the shortage, the charge oil too is supplied together.
When dynamic braking is activated, the pressure in the braking circuit is always unloaded through the orifice (23).
