Explore the components of the new A6:
1. Power steering motor More comfort, more agility
Since steering is safety-relevant, the reliability of its components has top priority, which is guaranteed by great ruggedness and the hollow-shaft motor used by ebm-papst.“
2. Orbital pump Equipped for cold
That is important because AdBlue crystallizes at low subfreezing temperatures. When the engine is switched off, the orbital pump returns the AdBlue from the hoses back to the AdBlue tank so that the liquid cannot freeze in the hoses. ebm-papst supplies the orbital pump as a module including the drive, pump and electronics. Benno Kilzer says, “Besides pumping in two directions, it also has another big advantage. Since it’s a diaphragm pump, it can’t freeze. A frozen medium can expand inside the pump without damaging it.”“
3. Oil pump Reliable at maximum load
The ebm-papst motor in the pump has to satisfy exacting requirements. Benno Kilzer explains: “The oil pump runs in the oil sump, the part of the transmission that is always submerged in oil. The motor has to withstand this transmission oil and also the high temperatures of up to 160 degrees.” The motor can do that thanks to a combination of materials and design exactly tailored to Audi’s requirements.
