Description A 6 VM DA 5 with Switching Solenoids:
Electrical travel direction valve and Qmin – circuit
Travel range rabbit (road travel), forward:
Electrical switching solenoid (a) current less in connection with travel direction switch.
The high pressure side A is pressurized, so the high pressure can, on the one hand, act
on the regulator piston (ring surface) via the check valve and the switching solenoid (a)
and, on the other hand, on the control spool ring surface.
Electrical switching solenoid (b) currents in connection with quick / slow switch.
Thus the corresponding speed-dependent control pressure can act on the big regulator
piston surface. This effects that the travel motor is set to Qmin (small swash plate angle)
(rabbit) as with any other DA-regulation. When charged (increasing high pressure), the
travel motor automatically regulates back to Qmax (big swash plate angle) (tortoise) from
the regulation start adjusted.
Travel range rabbit (road travel), reverse:
Switching solenoid (a) under current
The high pressure side B is pressurized. So the description given under travel range rabbit
(road travel) forWard applies.
Travel range tortoise (working), forward:
Switching solenoid (a) currents
Functioning as described under travel range rabbit (road travel)
Switching solenoid (b) under current
The control pressure is not switched on the big surface of the regulator piston, solenoid
valve (b) is closed. The travel motor remains in Qmax position (big swash plate angle).
Hydrostatic brake:
By releasing the accelerator pedal the travel speed is reduced. The hydrostatic
transmission hereby acts as wear-resistant auxiliary brake.
