Rotary shaft brake system e.g. drum brake system, for rotor of aircraft, has control unit controlling displacement of friction elements between rest and braking positions, where control unit is attached to actuator comprising drive train

摘要

The system has a clamp (4) clamping two friction elements (2, 3) on two sides of a rotary braking element (1), where the friction elements are moved between two extreme positions. A guiding unit (5) guides the movement of the two friction elements on the clamp. A control unit (6) controls the displacement of the two friction elements between an extreme rest position and a braking position. The control unit is attached to an actuator i.e. linear actuator, that comprises a drive train (8) for controlling the friction elements.
