Vehicle wheel for a double-track vehicle or cover therefor

An external cover for a vehicle wheel for a double-track vehicle, the cover comprising:

• one or more passage openings, bounded by spokes extending substantially in a radial direction of the wheel cover, for providing cooling air interiorly of the vehicle wheel, the one or more passage openings opening in a lateral projection of the vehicle wheel;
• wherein the passage openings have a width in a radial direction that changes when viewed in a rotational direction of the vehicle wheel;
• and
• wherein, when viewed against a forward driving rotating direction of the wheel, the width of the one or more passage openings decrease such that a lever arm of a pressure force, which lever arm is with respect to the axis of rotation, occurring from airflow against the wheel when the vehicle is moving in the driving direction is reduced, wherein the lever arm of said pressure force is less than a lever arm of a suction force in relation to the axis of rotation.

A vehicle comprising:

• a first set of wheels;
• and
• a second set of wheels;
• wherein each wheel of the first and second sets of wheels comprises one or more passage openings, bounded by spokes extending substantially in a radial direction of the wheel, for providing cooling air interiorly of the wheel, the one or more passage openings opening in a lateral projection of the wheel;
• wherein the passage openings have a width in a radial direction that changes when viewed in a rotational direction of the vehicle wheel;
• and
• wherein, when viewed against a forward driving rotating direction of the wheel, the width of the one or more passage openings decrease such that a lever arm of a pressure force, which lever arm is with respect to the axis of rotation, occurring from airflow against the wheel when the vehicle is moving in the driving direction is reduced, wherein the lever arm of said pressure force is less than a lever arm of a suction force in relation to the axis of rotation.
