Patent number: 9689463Abstract: A roller (20) for a pendulum mass (4, 5, 6) of a centrifugal force pendulum (1), including a rolling section (42), a first maintaining section (26) and a second maintaining section (27). The maintaining sections have a larger diameter than the rolling section, and the roller (20) has a width (44) which is smaller or the same size as the first depth (9) of the centrifugal force pendulum. Due to roller (20), a centrifugal force pendulum can be constructed for particularly flat couplings. In particular, the total weight of the friction clutch is reduced and the mounting is simplified.Type: GrantFiled: July 30, 2013Date of Patent: June 27, 2017Assignee: Schaeffler Technologies GmbH & Co.
