Abstract
An aircraft rudder pedal includes a frame, a pair of pedals, an output shaft and a mechanical kinematic chain for transmitting to the output shaft a displacement of at least one of the pedals relative to the frame. The mechanical kinematic chain comprises a central transmission part able to be rotated relative to the frame by a displacement of one of the pedals relative to the frame. The mechanical kinematic chain also includes a transmission mechanism joining the central transmission part to the output shaft. The transmission mechanism includes a homokinetic association of two universal joints between said central transmission part and the output shaft.
Claims20
An aircraft acquisition system comprising at least two redundant acquisition sensors, each acquisition sensor comprising a fixed element and a movable element, the movable element being able to be moved relative to the fixed element, each acquisition sensor being able to generate an electrical measurement signal as a function of the position of the movable element relative to the fixed element over a useful electrical measurement travel,
- the acquisition system comprising a joint drive device coupled to the acquisition sensors and configured for jointly driving the acquisition sensors, the joint drive device being able to displace, for each acquisition sensor, the movable element relative to the fixed element of the acquisition sensor,
- the acquisition system also comprising an out-of-travel disabling system configured, for each acquisition sensor, for displacing the movable element relative to the fixed element outside the useful electrical measurement travel of the acquisition sensor, in the event of uncoupling of the joint drive device.
