Abstract
A cover for an electric motor in a vehicle wheel permits cooling air to be expelled from the motor but prevents foreign material from entering the motor. The cover is made of flexible, air and water impervious sheet material and has a disc-like configuration to fit an opening in the wheel at the cooling air exit from the motor. The cover has one or more openings therein sized to permit the desired flow of cooling therethrough. Each such opening is preferably covered by a foramenous material, such as scrim, to prevent foreign material from passing therethrough. Each such opening also is loosely covered with an impervious sheet, deflecting cover to keep precipitation away from the opening. A reinforcing wire attached to the perimeter of the cover has its circumference expanded by a toggle mechanism to facilitate attachment and removal of the cover.
