A two-piece magnet retention ring for an eddy-current fan drive mechanism.
First claim
Opening claim text (preview).
What is claimed is: 1 . A magnet retention ring for an eddy-current fan drive assembly comprising: a first annular base ring member; and a second annular magnet positioning ring member; said second annular magnet retention ring member being fixedly secured to said first annular bearing member; and said second annular magnet retention ring member has a plurality of through-openings for positioning for magnet members therein. 2 . The magnet retention ring as described in claim 1 further comprising a plurality of magnet members, with one of said magnet members being positioned in each of said plurality of through-openings. 3 . The magnet retention ring as described in claim 2 wherein each of said magnet members has a base surface which is positioned in contact with said first annular base ring member. 4 . The magnet retention ring as described in claim 3 wherein each of said magnet members has an upper surface which extends from said respective through opening. 5 . An eddy-current mechanism for a two-speed fan drive assembly comprising: a flux ring member; and a magnet retention ring member; said magnet retention ring member comprising: a first annular base ring member; a second annular magnet retention ring member; said second annular magnet positioning ring member being fixedly secured to said first annular bearing member; said second annular magnet retention ring member have a plurality of through-openings for positioning for magnet members therein; and a plurality of magnet members, with one of said magnet members being positioned in each of said plurality of through-openings. 6 . The magnet retention ring as described in claim 5 wherein each of said magnet members has a base surface which is positioned in contact with said first annular base ring member. 7 . The magnet retention ring as described in claim 6 wherein each of said magnet members has an upper surface which extends from said respective through opening. 8 . A two-speed fan drive assembly comprising: a pneumatic friction clutch mechanism; and an eddy current fan drive assembly; said eddy current fan drive assembly comprising: a flux ring member; a magnet retention ring member; said magnet retention ring member comprising: a first annular base ring member; a second annular magnet retention ring member; said second annular magnet retention ring member being fixedly secured to said first annular bearing member; said second annular magnet retention ring member having a plurality of through-openings for positioning for magnet members therein; and a plurality of magnet members, with one of said magnet members being positioned in each of said plurality of through-openings. 9 . The magnet retention ring as described in claim 8 wherein each of said magnet members has a base surface which is positioned in contact with said first annular base ring member. 10 . The magnet retention ring as described in claim 9 wherein each of said magnet members has an upper surface which extends from said respective through opening.
