Abstract
A load wheel for a vehicle is provided having a cylindrical hub with an axis, a first sidewall, a second sidewall, an outer surface, a central core extending coaxially within the hub, and a plurality of passageways extending in an axial direction between the first and second sidewall. A solid, non-pneumatic tire is bonded to the outer surface of the hub, and a set of bearing is mounted in the central core of the hub. The hub is characterized by a “heat factor” equal to the (hub mass×hub specific heat)/surface area exposed. The heat factor for a hub comprising passageways is compared to the heat factor for a solid hub to derive a heat factor ratio, which is used to select the exposed surface area of the hub and maintain the operating temperature of the wheel below the failure temperature.
