Abstract

An aircraft wheel and brake assembly includes a wheel, a brake configured to brake the wheel, and a measurement device configured to measure the speed of rotation of the wheel. The brake includes at least one friction member, an actuator support, and at least one brake actuator carried by the actuator support and configured to exert a braking force selectively on the friction member. The measurement device includes a target and a sensing component for producing a measurement signal representative of the speed of rotation of the target. The aircraft wheel and brake assembly is configured in such a manner that, when assembled, the target is constrained to rotate with the wheel and the sensing component is mounted on the actuator support. The target and the sensing component is configured in such a manner that the sensing component detects rotation of the target.

Dependent claims

An aircraft wheel and brake assembly, comprising:

a wheel mounted to rotate around a rotation axis;
a brake configured to brake the wheel, the brake comprising a friction member, an actuator support, and at least one brake actuator carried by the actuator support and configured to exert a braking force selectively on the friction member;
and
a measurement device configured to measure a speed of rotation of the wheel and comprising a target and a sensing component configured for producing a measurement signal representative of a speed of rotation of the target,
wherein the aircraft wheel and brake assembly are configured such that, when the aircraft wheel and brake assembly is assembled, the target is constrained to rotate with the wheel and the sensing component is directly mounted on the actuator support, the target and the sensing component being configured such that the sensing component detects rotation of the target, the brake actuator extending between the rotation axis of the wheel and the sensing component when looking in a direction perpendicular to said axis of rotation.
