Abstract
Official abstract text for this publication.
A ball stud (12) with a relatively short grip length, adapted for use with a turbocharger, having a flexible flange (18) extending from a center of the ball stud (12). The flexible flange (18) is between a ball section (14) and a first shaft portion (20) adjacent to the flexible flange (18) and preferably a narrower threaded shaft portion (22) extending further from the ball section (14). The first shaft portion (20) may be tapered to fit in a complementary aperture (32) of a plate (30). The flexible flange (18) preferably includes a narrow circumference (24) adjacent to a center of the ball stud (12) with a circumferential lip (26) adapted to engage a plate (30). The flexible flange (18) allows subtle flex for thermal expansion and essentially changes a spring rate of the ball stud (12) to emulate a longer fastener.
First claim
Opening claim text (preview).
What is claimed is: 1. A ball stud ( 12 ) having a nominal bolt diameter, a grip length less than six-times the nominal bolt diameter adapted for use with a turbocharger, the ball stud ( 12 ) including a flexible flange ( 18 ) extending from a center of the ball stud ( 12 ) between a ball section ( 14 ) on a ball side of the flexible flange ( 18 ) and a first shaft portion ( 20 ) on a shaft side of the flexible flange ( 18 ), wherein the flexible flange ( 18 ) includes a circumferential lip ( 26 ) and an intermediate section ( 24 ) between the center of the ball stud ( 12 ) and the circumferential lip ( 26 ), wherein the intermediate section exhibits flex, and wherein the flexible flange ( 18 ) changes a spring rate of the ball stud ( 12 ) to emulate a spring rate of the ball stud ( 12 ) having a grip length greater than six-times nominal bolt diameter. 2. The ball stud ( 12 ) of claim 1 wherein the first shaft portion ( 20 ) is tapered and adjacent to the flexible flange ( 18 ). 3. The ball stud ( 12 ) of claim 1 further comprising a threaded shaft portion ( 22 ) extending further from the ball section ( 14 ). 4. A ball stud ( 12 ) having a nominal bolt diameter, a grip length less than six-times the nominal bolt diameter-adapted for clamping multiple plates for use with a turbocharger, the ball stud ( 12 ) including a flexible flange ( 18 ) extending from a center of the ball stud ( 12 ) between a ball section ( 14 ) and a first shaft portion ( 20 ) adjacent to the flexible flange ( 18 ) and a threaded shaft portion ( 22 ) extending further from the ball section ( 14 ), wherein the first shaft portion ( 20 ) is adapted for use in association with a first plate ( 30 ) and the threaded shaft ( 22 ) is adapted for use in association with a second plate ( 40 ) wherein the flexible flange ( 18 ) includes a circumferential lip ( 26 ) and an intermediate section ( 24 ) between the center of the ball stud ( 12 ) and the circumferential lip ( 26 ), wherein the intermediate section exhibits flex, and wherein the flexible flange ( 18 ) changes a spring rate of the ball stud ( 12 ) to emulate a spring rate of the ball stud ( 12 ) having a grip length greater than six-times nominal bolt diameter. 5. The ball stud ( 12 ) of claim 4 wherein the first shaft portion ( 20 ) is tapered away from the flexible flange ( 18 ) to fit in a complementary plate aperture ( 32 ) of the first plate ( 30 ).
