## Abstract

The invention solves the issue of stiff mounting of a wheel to a bicycle frame. The essential feature of the invention is that in the seating nests of the axle are bulges and hollows with slanting surfaces. The outer contour of the axle's wall section, which is parallel to the wheel symmetry plane which goes through the slanting surface, has a non-circular shape, preferably the shape of a regular polygon or similar to a regular polygon or an irregular polygon or the shape of an irregular closed curve.

## Claims

### Claim 1

A vehicle wheel axle in the form of a tube made of metal or carbon fibre-reinforced composite material, wherein in seating nests of the axle comprise bulges and hollows with reversely slanting surfaces, while an outer contour of a section of the axle wall being parallel to a symmetry plane of the wheel, which goes through the slanting surfaces, has a non-circular shape and wherein the axle is seated in a hook of a frame for the reversely slanting surfaces and is secured with an elastic tape having stiff pads which have a shape that meshes with the slanting surfaces of the axle.

### Claim 2 (depends on 1)

The vehicle wheel axle according to claim 1 wherein in the seating nests has a circumference and around the circumference are V-shaped narrowing whose side surfaces are situated askew inwards in the direction of the centre of the narrowings, and whereas the outer contour of the wall section of the axle is parallel to the symmetry plane of the wheel going through the slanting surface and wherein the non-circular shape is that of a regular polygon, an irregular polygon, or the shape of an irregular closed curve.

### Claim 3 (depends on 1)

The vehicle wheel axle according to claim 1 wherein the seating nests have on their circumference bulges comprising a sawtooth shape, whereas the outer contour of the section of the axle wall, parallel to the wheel symmetry plane which goes through the slanting surface of the bulges has the non-circular shape that is the shape of a regular polygon, an irregular polygon, or the shape of an irregular closed curve.

### Claim 4 (depends on 1)

The vehicle wheel axle according to claim 1 wherein the seating nests have on their circumference a bulge which comprises two slanting surfaces, and whereas the outer contour of the section of the axle wall, parallel to the wheel symmetry plane which goes through the slanting surface has the non-circular shape that is the shape of a regular polygon, an irregular polygon, or an irregular closed curve.

### Claim 5 (depends on 1)

The vehicle wheel axle according to claim 1, wherein the outer contour of the wall sections parallel to the wheel symmetry plane which goes through the slanting surfaces on one end of the axle is a mirror reflection of the contours of those wall sections on the other end of the axle.
