Claims20
A brake axle assembly comprising:
- an axle;
- and
- a sacrificial brake axle sleeve disposed circumferentially around the axle, wherein the sacrificial brake axle sleeve comprises a plurality of recesses separated by splines and asymmetrically disposed about an inner circumference of the sacrificial brake axle sleeve, wherein the axle is in contact with the splines, wherein the plurality of recesses decrease a contact surface area between the sacrificial brake axle sleeve and the axle.
A sacrificial brake axle sleeve comprising a plurality of recesses in an inner circumference of the sacrificial brake axle sleeve, wherein the plurality of recesses are asymmetrically disposed about the inner circumference, wherein the plurality of recesses are separated by splines, wherein the splines are configured to contact an axle, wherein the plurality of recesses are configured to decrease a contact surface area between the sacrificial brake axle sleeve and the axle.
A brake system for an aircraft comprising:
- an axle located within a sacrificial brake axle sleeve,
- wherein the sacrificial brake axle sleeve comprises a first circumferential region and a second circumferential region, and wherein a stiffness of the first circumferential region is greater than a stiffness of the second circumferential region, wherein the first circumferential region comprises a first plurality of splines, wherein the second circumferential comprises a second plurality of splines, wherein the axle is in contact with the first plurality of splines and the second plurality of splines, wherein a contact surface area between the axle and the sacrificial brake axle sleeve is greater in the first circumferential region than the second circumferential region.
