Shift Pressure Shift Valve
WARNING: This page is about a different variant/trim than selected.
| 1 - 1-2/4-5 COMMAND VALVE |
| 2 - DRIVING CLUTCH K1 |
| 3 - HOLDING CLUTCH B1 |
| 4 - 1-2/4-5 SHIFT PRESSURE SHIFT VALVE |
When the multiple-disc brake B1 (3) is activated, the working pressure (p-A) 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.
