Abstract

Disclosed herein is a monobloc and removable pedal module for an aircraft rudder bar. The pedal module, which is intended for a rudder bar, includes a pedal, at least one integrated adjustment system, and a connection device which enables a removable connection of the pedal module to be produced. The pedal module is a monobloc component in order to simplify and facilitate its replacement via the removable connection obtained by the connection device.

First claim

What is claimed is:

1. A monobloc pedal module for an aircraft rudder bar, the monobloc pedal module being configured to be connected to a central module of a rudder bar, the monobloc pedal module comprising:
a single pedal;
at least one integrated adjustment system configured to enable the adjustment of an angle of inclination of the pedal; and
a connection device which enables a removable connection of the pedal module to be produced.

2. The pedal module as claimed in claim 1 , further comprising an integrated braking system.

3. The pedal module as claimed in claim 2 , wherein the braking system comprises a position sensor which is configured to measure a rotation of the pedal during a braking action.

4. The pedal module as claimed in claim 3 , wherein the position sensor is installed in a first housing which is arranged in a lower portion of the pedal.

5. The pedal module as claimed in claim 1 , wherein the adjustment system is capable of being controlled.

6. The pedal module as claimed in claim 5 , wherein the adjustment system comprises a geared motor which is capable of being controlled.

7. The pedal module as claimed in claim 6 , wherein the adjustment system comprises a screw which is capable of being rotated by the geared motor, the screw acting on a nut which is configured to tilt a bell crank during the rotation of the screw, the bell crank being provided with a roller which is arranged so as to be in contact with a roller track which is formed on the pedal and to push the pedal when the bell crank is tilted in order to modify the inclination thereof.

8. The pedal module as claimed in claim 6 , wherein the geared motor is installed in a second housing which is arranged in a lower portion of the pedal.

9. The pedal module as claimed in claim 4 , wherein the pedal is provided with at least one access hatch which affords access to at least one of the first and second housings, the access hatch being arranged on a support face of the pedal.

10. The pedal module as claimed in claim 9 , further comprising at least one automatic extraction system which is configured to automatically extract an element which is installed in the housing in the event of the opening of the access hatch of the housing.

11. The pedal module as claimed in claim 1 , further comprising a hollow monobloc carrier structure on which the pedal is rotatably mounted.

12. The pedal module as claimed in claim 11 , further comprising a protection bellows which is arranged between the pedal and the carrier structure.

13. A rudder bar for an aircraft, the rudder bar comprising at least one pedal module as claimed in claim 1 .

14. The rudder bar as claimed in claim 13 , further comprising at least one central module and two pedal modules, the pedal modules being arranged at one side and the other of the central module, each of the pedal modules being arranged on an associated lateral face of the central module.

15. The rudder bar as claimed in claim 14 , wherein the central module is provided on each of the lateral faces with guide rails which are configured to cooperate with recirculating ball bearing tracks which are fixed to the associated pedal module and which form part of the connection device.

16. The rudder bar as claimed in claim 14 , wherein the central module is provided on each of the lateral faces with an arm, each of the arms being connected in an articulated manner to a push rod of the corresponding pedal module, the arm and the push rod being configured to ensure the transmission of a movement of the pedal of the pedal module.

17. An aircraft comprising a rudder bar as claimed in claim 13 .
