Nietverbindung und Verfahren um zwei Teile mittels Nieten zu verbinden

摘要

A pin connection structure is used in a floating type brake disc assembly. The assembly is made up of a hub (2), and an annular disc (3) which is concentrically disposed around the hub (2) with a clearance (4) therebetween. The hub (2) and the disc (3) have plural sets of semicircular connecting dents (5, 6) opening toward the clearance (4) to thereby form respective inserting holes (7). A hollow pin (8) is inserted into each of the inserting holes (7) with a washer (11) fitted on that one end of the hollow pin (8) which is subsequently caulked radially outward for fixing the washer (11) in position. The hollow pin (8) is made of a metal having a surface-treated layer, and the caulked end of the hollow pin (8) is formed into a convex shape in at least part of the end portion.
