Abstract
A damper assembly including an input member, an output member, and a transfer assembly is disclosed. The input member is configured to receive a torsional input. The output member is configured to provide a torsional output. The transfer assembly is coupled between the input member and the output member and includes a ring, a first guide, a second guide, a first spring, and a second spring. The ring defines a first linear slide path that has a first end and a second end, and a second linear slide path that has a third end and a fourth end. The first guide is slideable within the first linear slide path and coupled to the input member. The second guide is slideable within the second linear slide path and coupled to the input member. The first spring is positioned between the first guide and the second end of the first linear slide path. The second spring is positioned between the second guide and the fourth end of the second linear slide path. Movement of the input member relative to the output member causes the first guide to slide along the first linear slide path and the second guide to slide along the second linear slide path.
