Abstract
Abstract A wheel axle for a single-axle trailer has a fixed axle housing in the form of a polygonal tube and an inner rod of polygonal cross-section traversing that tube as a support for a pair of wheel mounts secured to its ends; the polygon of the outer tube has twice as many corners as that of the inner rod to form therewith a set of pockets of generally triangular profile with obtuse vertex angles receiving elongate , elastically deformable damping strips to enable limited relative rotation between the rod and the tube. The strips may be partly received in surface depressions of the rod.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
158 words
A wheel axle for a single-axle vehicle, comprising: a tubular axle housing of generally polygonal cross-section; a rod of generally polygonal cross-section traversing said axle housing with freedom of relative rotation, said rod having a pair of extremities projecting from said axle housing, the polygon of said axle housing being of a higher order than that of said rod and forming a first set of corners confronting respective corners of the rod polygon along with a second set of corners confronting the sides of said rod polygon to form therewith elongate pockets of generally triangular profile, all of said corners of the housing polygon having obtuse angles; a pair of laterally extending arms secured to said extremities, said arms being provided with wheel bearings offset from the axis of said rod; and a plurality of elongate damping strips of elastically deformable material respectively received in said pockets to resist relative rotation of said rod and said axle housing.
Claim 2
Dependent Claim
158 words
A wheel axle for a single-axle vehicle, comprising: a tubular axle housing of generally polygonal cross-section; a rod of generally polygonal cross-section traversing said axle housing with freedom of relative rotation, said rod having a pair of extremities projecting from said axle housing, the polygon of said axle housing being of a higher order than that of said rod and forming a first set of corners confronting respective corners of the rod polygon along with a second set of corners confronting the sides of said rod polygon to form therewith elongate pockets of generally triangular profile, all of said corners of the housing polygon having obtuse angles; a pair of laterally extending arms secured to said extremities, said arms being provided with wheel bearings offset from the axis of said rod; and a plurality of elongate damping strips of elastically deformable material respectively received in said pockets to resist relative rotation of said rod and said axle housing.
Claim 3
Dependent Claim
22 words
A wheel axle as defined in claim 1 wherein the number of sides of said rod is at most equal to four.
Claim 4
Dependent Claim
26 words
A wheel axle as defined in claim 2 wherein the number of corners of said axle housing is double the number of corners of said rod.
Claim 5
Dependent Claim
28 words
A wheel axle as defined in claim 3 wherein the angles of at least one set of corners of said housing polygon are equal to at least 120*.
Claim 6
Dependent Claim
33 words
A wheel axle as defined in claim 4 wherein the polygon of said axle housing is a hexagon, the angles of said first set exceeding the angles of said second set of corners.
Claim 7
Dependent Claim
33 words
A wheel axle as defined in claim 4 wherein the polygon of said axle housing is an octagon, the angles of said first set substantially equaling those of said second set of corners.
Claim 8
Dependent Claim
21 words
A wheel axle as defined in claim 1 wherein said axle housing is internally rounded at said second set of corners.
Claim 9
Dependent Claim
25 words
A wheel axle as defined in claim 1 wherein said sides of said rod are concave and form elongate troughs partly receiving said damping strips.
Claim 10
Dependent Claim
142 words
A wheel axle for a single-axle vehicle, comprising: a tubular axle housing of generally polygonal cross-section; a rod of generally polygonal cross-section traversing said axle housing with freedom of relative rotation, said rod having a pair of extremities projecting from said axle housing, the sides of the rod polygon being provided with central longituDinal troughs of arcuate profile and forming clearances with confronting corners of the polygon of the axle housing, said axle housing being rounded at said confronting corners with a radius of curvature approximately equaling that of said troughs; a pair of laterally extending arms secured to said extremities, said arms being provided with wheel bearings offset from the axis of said rod; and a plurality of elongate damping strips of elastically deformable material respectively received in said clearances to resist relative rotation of said rod and said axle housing.
