Foldover tab for retainer spring stop

摘要

A vibration damper, including a cover plate with an annular portion, and a spring portion including spring retaining portions forming respective spaces and a spring blocking portions including respective protrusion segments and respective tab segments including respective portions of an edge of the cover plate and having a same first thickness. The damper includes springs at least partially located in the respective spaces, and having respective longitudinal ends, and a second cover plate or output flange connected to the cover plate. The springs are arranged to transmit torque to the cover plate. The respective protrusion segments have a same second thickness and include respective protrusions. Respective first portions of the longitudinal ends of the springs are engaged with the respective protrusions. Respective second portions of the longitudinal ends of the springs are engaged with the respective tab segments.
