Abstract
A vehicle wheel for a double-track vehicle or an external cover therefor is provided, having passage openings, particularly for a cooling air flow for a wheel brake provided on the interior side of the wheel, in the lateral projection. The passage openings have a width in the radial direction which changes when viewed in the circumferential direction such that, viewed against the rotating direction of the wheel when the vehicle is driving forward, the above-mentioned width Viewed in the radial direction, centers of the virtual segments of the passage opening which follow one another against the rotating direction move in the direction of the wheel center. As a result, the force as well as the lever arm of the drag is reduced, so that a moment of resistance is obtained which is significantly decreased. The passage openings are preferably bounded by spokes extending essentially in the radial direction.
