DSC Unit: Construction: Notes
The DSC unit consists of the DSC control unit and the hydraulic unit. The hydraulic unit comprises principally the valve block and the pump motor. The following components are integrated in the valve block:
- 2 pump elements driven by eccentric shafts (front-axle brake circuit and rear-axle brake circuit)
- 2 intake valves, 2 switchover valves and 4 inlet valves and 4 outlet valves (12 solenoid valves)
- Internal brake pressure sensor
- 2 accumulators
The (design-related) separating line between the DSC control unit and the hydraulic unit runs through the solenoid valves. The electrical components of the solenoid valves (valve coils) are assigned to the DSC control unit and are directly connected to the board. The mechanical components of the valve (principally the valve domes with the tappets) are affixed to the hydraulic unit.
