Rotary-shaft brake system, in particular for an aircraft rotor or propeller, including a linear acturator

摘要

Rotary-shaft brake system includes a rotary braking member attached to a rotary shaft,
first and second friction members arranged on either side of the rotary braking member, each friction member being moveable between a first braking position when the friction members are in contact with the rotary braking member and a second idle position away from the rotary braking member, a bracket holding the friction members and means for guiding and controlling movement of the friction members on the bracket.;The control means comprises a linear actuator acting on at least a first lever and a solid elastically deformable element.

1. Rotary shaft brake system including:
at least one rotary braking member attached to said rotary shaft and turning therewith, at least one first friction member and one second friction member arranged on either side of said at least one rotary braking member, each friction member being moveable between two extreme positions, a first “braking” position when the first friction member and the second friction member are in contact with the rotary braking member and a second “idle” position when they are moved away from the rotary braking member, a bracket for holding the first friction member and the second friction member on either side of the rotary braking member, means for guiding the movement of the first friction member and of the second friction member on the bracket, means for controlling the movement of the first friction member and of the second friction member between the extreme braking and idle positions thereof, including an actuator linked to a transmission system for controlling the first friction member and the second friction member, in which said actuator is a linear actuator acting on at least a first lever incorporated in series into said transmission chain for controlling said at least first and second friction members.
