- Transmission 722.9
- Regelmagnetventil Lamellenbremssteuerung B3

Component Identification:

Location
The multidisk brake control solenoid valve B3 is mounted on the fully integrated transmission control controller unit.

Component Identification:

Task
The multidisk brake control solenoid valve B3 is actuated by the fully integrated transmission control control unit and influences the position of the regulating valve B3. The pressure in the multidisk brake B3 depends on the position of the regulating valve and therefore on the geometry of the regulating valve B3.

The multidisk brake control solenoid valve B3 has a rising characteristic. This means that the oil pressure applied in the B3 regulating valve increases as the actuation current increases. In limp-home mode of the fully integrated transmission control (VGS) all the control solenoid valves are de-energized. The multidisk brake control solenoid valve B3 thus supplies no pressure.

Body
In the multidisk brake control solenoid valve B3, a proportional solenoid converts the electrical signals from the fully integrated transmission control control unit. The float needle can also be moved into intermediate positions as a result.

Function
The multidisk brake control solenoid valve B3 assigns a proportional pressure to the current which is controlled by the fully integrated transmission control control unit.
