Study Notes
Brake System Overview
- The vehicle uses several brake systems, primarily the joystick/brake lever for normal braking and a rapid emergency application.
- The EP brake system is used, with one Brake Control Unit (BCU) per unit.
- If the BCU fails, the TCU will take over its functions.
- A backup indirect brake system, operated by two automatic brake valves (one for the driver, one for the guard), is also present.
- The primary brake type is electric, allowing brake force return to the contact line network (OHE).
- If network return isn't possible, the brake current is routed through a resistance, reducing magnetic drag to 0 kN within 1 second.
- An electro-pneumatic brake system handles magnetic drag after that.
- A spring-loaded brake system secures parked units across all axles of the DTC/NDTC.
- Application and release of the spring-loaded brake is via push buttons in the driver's cab.
- An air shut-off cock secures the brake in case of fault, requiring manual emergency release.
- Pneumatic brake activation begins at 15 km/h, with electronic brake force reduction dependent on speed (15-3 km/h) and automatic reduction below 3 km/h.
- "Special brake blending" is the proportional reduction of electronic braking as compressed-air braking is increased.
Brake System Details
- Diagrams and figures detail specific components, schematics, connections, and specific components in the brake systems, including EP units, BCU/SKS, Analog Input, Triple Valves, and Stabilising Valves.
- Diagrams show components like pressure ranges, specifying pressures of 3.6 bar and 1.6 bar.
- Different configurations are shown in diagrams: DTC – MC – TC, and NDTC – MC – TC
- Detailed diagrams show the relationships between these components.
Additional Notes
- Multiple diagrams illustrate the brake system components, connections, and operation, including vehicle configurations such as DTC–MC–TC and NDTC–MC–TC setups.
- The spring-loaded brake system acts on all axles of the DTC/NDTC .
- In case of a broken hose, the spring-loaded brake applies automatically. A shut-off valve is necessary for emergency release.
- A special lever-based emergency release exists for the spring-loaded brake, activated via a shut-off cock.
