Disc brake for an aircraft wheel

摘要

The invention relates to a disc brake for an aircraft wheel, comprising friction discs (20,30), including rotor discs and stator discs, a structure comprising a torsion tube (11) on which the discs are fitted, a rear plate (12) which is located at one end of the tube, and a support (13) for braking actuators (14,15) at another end of the tube, the actuators being able to be selectively activated in order to apply a pressing force to the discs. According to the invention, the discs are separated into two groups, including a first group (20) which can be used alone for taxiing braking operations, and a second group (30) which can be used alone or in conjunction with the first group for take-off/landing braking operations.

主权项

1. A disk brake for an aircraft wheel, comprising:
a plurality of friction discs (20,30; 120,130), including rotor discs and stator discs; a plurality of braking actuators (14,15,16; 114); a structure comprising a torsion tube (11; 111) on which the plurality of friction discs are fitted, a rear plate (12; 112) which is located at one end of the tube, and a support (13; 113) for the plurality of braking actuators at another end of the tube, each actuator in the plurality of actuators being activate able in order to selectively apply a pressing force to the plurality of discs; wherein the plurality of discs comprise two separate groups, including a first group of friction disks (20,120) which is pressed alone by said actuators for braking operations below a specific braking torque threshold, and a second group (30,130) of friction disks which is pressed alone or in conjunction with the first group of disks by said actuators for braking operations above said torque threshold.
