Shift Valve Holding Pressure
The holding pressure shift valve is actuated by the pressures present at the end face in the actuators and a spring.
It assigns the working pressure to the actuator with the higher pressure (taking into account the spring force and the
effective surface area). The other element of the shift group is then unpressurized. The valve switches over only
during the shift phase and only at a certain pressure ratio between the overlap pressure (p-Ü) and the shift pressure
(p-S).
Shift Pressure Shift Valve
When the multiple-disc brake B1 (3) is activated, the working pressure (pa) is applied to the end face of the 1-2 /
4-5 shift pressure shift valve (4) via the command valve (1). Its shift state is maintained during the shift phase by
substituting the shift element pressure acting on its end face (and which is variable during the shift phase) with a
corresponding constant pressure. When the multi-plate clutch K1 (2) is activated, the end face of the shift valve is
unpressurized during the stationary and shift phases, so the shift state is maintained during the shift phase in this
case too.
