    • The invention relates to a vehicle wheel for a double-track vehicle or an external cover therefor, 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 having 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 decreases, and in that the—viewed in the radial direction—centers of the virtual segments of the passage opening which follow one another against the rotating direction move quasi (virtually) 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.
    • 本发明涉及一种用于双轨车辆或其外盖的车轮,具有通道开口,特别是用于在侧向突起中设置在车轮内侧的车轮制动器的冷却空气流,通道开口 具有沿圆周方向观察时沿径向变化的宽度,使得当车辆向前行驶时,相对于车轮的旋转方向观察,上述宽度减小,并且在径向上观察 - 相对于旋转方向彼此相对的通道开口的虚拟段的中心在轮中心的方向上准确地(虚拟地)移动。 结果,阻力的力和杠杆臂减小,从而获得显着降低的电阻力矩。 通道开口优选地由基本上沿径向方向延伸的辐条限定。
