Abstract
A system and method for absorbing rock-back and oscillation in a drive assembly of an engine start-stop device. The drive assembly has a pinion with at least two slots that receive axially extending protrusions of a barrel element. Damping elements in the slots and a spring element absorb rock-back and impact oscillations.
