AERODYNAMICALLY EFFICIENT SPOKE DESIGN FOR A VEHICLE WHEEL

WIPO Patent Application WO/2014/145182

A8

A wheel for a vehicle includes an inner hub portion that is configured to receive an axle therethrough and which defines an axis of rotation at a center thereof. The wheel includes an outer rim portion. A plurality of wheel spoke portions extend generally between the inner hub portion and the outer rim portion. The inner hub portion, the outer rim portion, and the plurality of spoke portions cooperate to form a wheel outer surface having a plurality of turbine openings. The outer surface of the wheel defines a wheel reference plane that is oriented generally perpendicular to the axis of rotation. The wheel outer surface is the side that face away from a vehicle. Each of the plurality of wheel spoke portions has an outer side adjacent the wheel outer surface, an inner side opposite the outer side, a leading side surface and a trailing side surface. The inner side of each of the plurality of spoke portions has a first edge adjacent the leading side surface that is spaced a first distance (Dle) apart from the wheel reference plane (P) and a second edge adjacent the trailing side surface that is spaced a second distance (Dte) apart from the wheel reference plane (P). The inner side of the spoke is configured such that the first distance is less than the second distance.
