Abstract

The present invention relates to a wheel hub for vehicle axle used in trucks, buses, trailers and semi-trailers, consists of a cylindrical central body, said central body surrounded by a plurality of radial projections extending vertically from the median region of said central body, being structured by ribs integrated with said projections providing robustness, reduced weight and reduced heat transfer from the brake to tires.

Claims

1. A wheel hub for vehicle axle, comprising:

a cylindrical central body comprising a longitudinal axis, a first lateral end and a second lateral end;

a plurality of radial projections that surround the cylindrical central body and that vertically extend from a median region of the cylindrical central body;

radial openings formed by the plurality of radial projections so that open passages are formed between the plurality of radial projections that extend from the first lateral end to the second lateral end of the cylindrical central body;

an orifice disposed at an end portion of each of the plurality of radial projections; and

ribs respectively integrated into the plurality of radial projections, at least three of the ribs equipped with guides for wheels, each rib formed by a radial protrusion with a lateral dimension that extends from a corresponding one of the radial projections in a direction parallel to the longitudinal axis, a width of each rib being substantially constant along the lateral dimension and less than a width of a corresponding radial projection, the ribs beginning from the median region of the cylindrical central body and extending vertically up to the guides.

2. A wheel hub for vehicle axle, according to claim 1, wherein the at least three of the ribs extend axially beyond other ones of the ribs.
