Operating Principle of Oscillating Motors

Operating Principle of Oscillating Motors





The oscillating motor has three functions to perform:
^ It guides the torque into the two halves of the stabilizer bar.
^ It decouples the two halves of the stabilizer bar.
^ In the event of system failure (fail-safe mode), the front axle stabilizer bar creates sufficient damping via the oscillating motor hydraulic fluid (hydraulic locking). It now works like a conventional stabilizer bar. Exception: If the oscillating motor chambers no longer contain any fluid as a result of a leak, the front axle stabilizer bar can no longer create damping.
Since one half of the stabilizer bar is connected to the shaft, and the other with the housing, the two halves turn in opposite directions.
The shell is forced upwards on the outside of a curve, and dragged down on the inside of a curve.
The maximum body torque on the front and rear axle occurs when there is a high degree of lateral acceleration. The system pressure is then 180 bar at the front axle and 170 bar at the rear axle.
