Piloting device for piloting an aircraft having a protected force sensor
First Claim
1. A piloting device for piloting an aircraft comprising:
- a piloting member (11) suitable for being actuated by a pilot,a mechanism (13) for mounting and guiding in rotation the piloting member (11) about at least one rotation axis (15, 16) with respect to a frame (12),stops (25, 26, 35, 36) adapted to limit angular amplitude of rotation of the piloting member (11) with respect to the frame,at least one force sensor (19) connected to the piloting member (11) upstream of said mechanism (13), and comprising at least one sensing element (20) deformable according to deformation modes corresponding to the measurement of at least one component of forces imparted by a pilot on the piloting member (11),wherein;
said stops (25, 26, 35, 36) are arranged so as to cooperate with bearing surfaces (32, 33, 37, 38) integral with the piloting member (11) upstream of said mechanism (13),said at least one force sensor (19), said stops (25, 26, 35, 36), and said bearing surfaces (32, 33, 37, 38) are arranged with respect to one another so that each contact of one of said bearing surfaces (32, 33, 37, 38) with a respective one of said stops (25, 26, 35, 36) generates an abutment reaction (R1, R2), the orientation of which with respect to each said at least one sensing element (20) of said at least one each force sensor (19) is such that said abutment reaction (R1, R2) stresses the respective said sensing element (20) at least substantially outside the deformation modes of the respective said sensing element (20).

Abstract
A piloting device for piloting an aircraft includes a piloting member (11), a mechanism (13) for mounting and guiding in rotation the piloting member about at least one rotation axis with respect to a frame (12), stops (25, 26, 35) arranged so as to cooperate with bearing surfaces (32) integral with the piloting member upstream of the mechanism in order to limit the rotation amplitude thereof, and at least one force sensor (19), these being arranged with respect to one another so that each contact of a bearing surface (32) with a stop (25, 26, 35) generates an abutment reaction, the orientation of which with respect to each deformable sensing element of each force sensor is such that it stresses this deformable sensing element at least substantially outside its deformation modes.
