Floating brake disk assembling method

摘要

Provided are a floating brake disk assembling method and a floating brake disk, and a floating brake disk assembling device, wherein a washer or a spring member can be accurately attached to a coupling pin. In the floating disk brake assembling method, a coupling pin 32 for coupling a brake disk (10) to a hub disk (20), which has a cylindrical body portion (41) to be mounted in a coupling hole (31), a first jaw portion (42) formed in one end portion of the body portion (41), and a portion to be swaged (43A) continuous to the other end portion of the body portion (41), is used; and the portion to be swaged (43A) is swaged so that a second jaw portion (42) having a diameter larger than that of the body portion (41) can be formed. The second jaw portion is formed by swaging the portion to be swaged (43A) while the coupling pin (32) is mounted in the coupling hole (31), and the spring member (33) and the washer (34) are attached to the outside of the coupling pin (32), to compress and deform the spring member (33) via the washer (34).

主权项

1. A method for assembling a floating brake disk, the floating brake disk comprising
an annular plate braking disk having a plurality of braking side connecting concave portions formed on an inner circumferential portion of the braking disk, a hub disk having a plurality of hub side connecting concave portions opposed to the braking side connecting concave portions on an outer circumferential portion of the hub disk and fitted to an inside of the braking disk, a connecting pin mounted in a connecting hole formed by butting both of the connecting concave portions together, and a spring member attached to an outside of the connecting pin, the connecting pin including a cylindrical body portion to be attached to the connecting hole with substantially no space between the body portion and the connecting hole, a first flange portion formed on one end portion of the body portion and having a diameter larger than the diameter of the body portion and a to-be-swaged portion continuously provided on the other end portion of the body portion and capable of forming a second flange portion having a diameter larger than the diameter of the body portion by swaging the to-be-swaged portion, wherein the connecting pin is mounted in the connecting hole, the spring member is attached to the outside of the connecting pin, and wherein the spring member is compressed and deformed such that the spring member is being compressed and deformed prior to and during the swaging to form the second flange portion.
