Aircraft wheel

An aircraft tire wheel assembly comprising a pair of wheel members with an axial center line, each wheel member having a rim member for abutting the spaced beads of a pneumatic tire, an annular groove in one said wheel members, an annular recess in the other one of said wheel members, said groove having an arcuate portion and a linear portion in transverse cross-section, a lock ring mounted in said groove and extending into said recess, said lock ring having a lobe section and a leg section, the cross-sectional shape of said leg section having an outer linear portion and an inner linear portion, the cross-sectional shape of said lobe section has a curvilinear portion and a linear portion, one end of said curvilinear portion merges with said outer linear portion, said linear portion of said lobe section intersects said inner linear portion, and said groove in said one wheel member is complimentary in shape to that portion of said lock ring that has said curvilinear portion and said linear portion that intersects said inner linear portion of said leg section.

An annular locking ring for an aircraft wheel assembly comprising a lobe section and a leg section, the cross-sectional shape of said leg section has a pair of spaced linear portions, the cross-sectional shape of said lobe section has a curvilinear portion and a pair of spaced linearly extending portions, one of said pair of linear portions of said lobe section is a first linear portion and the other one of said pair of linear portions is a second linear portion,

• said curvilinear portion has one end that merges into one end of said first linear portion, the other end of said first linear portion intersects one end of one of said spaced linear portions of said leg section, the other end of said curvilinear portion terminates into one end of said second linear portion,
• the other end of said second linear portion of said lobe section intersects the extension of the other one of said spaced linear portions of said leg section, and
• said lobe section having a cross section that is greater in dimension than the distance between said pair of spaced linear portions of said leg section as measured along a line that is normal to one of said spaced linear portions of said leg section.
