Abstract

The present invention solves the problem of rigid mounting of the wheels to the bicycle frame. The main feature of the invention is that the seating portion of the axle comprises a raised portion and a hollow portion with inclined surfaces (4) and (5) or (9) and (10) or (13) and (14). Outer profile (6) of the wall section (7) of the axle (1) parallel to the plane of symmetry of the wheel and passing through the inclined surfaces (4) and (5) or (9) and (10) or (13) and (14) ) has a non-circular shape, which is preferably a regular polygon or an approximate regular polygon or an irregular polygon or an irregular closed curve.

Description

technical field [0001] The subject of the invention is a vehicle axle, in particular a vehicle axle for a bicycle. Background technique [0002] An important issue in the design of a bicycle is to mount the wheels to the frame in such a way that the resulting assembly is stable and rigid. A substantially stable mount should not allow any movement of the axle relative to the fork or rear rocker. There are many known designs of this assembly, which show that it is difficult to obtain an efficient technical solution for securing the wheel to the fork. An axle to fork leg connection assembly is known from US Patent Specification No. US20060087096, where the leg sits on the axle from the top and the axle is on one end via a hemispherical clamp attached in an articulated manner Instead, it is fixed to the fork leg from below, and the axle has a swivel lock connected eccentrically to the clamping lever at the other end. An assembly in which a wheel axle is connected to a fork le...
