Clutch having a starter ring gear and an ignition timing mark

摘要

An automotive clutch comprises a single support ring for carrying a starter ring gear and an ignition timing mark. The support ring comprises a radial portion and an axial portion the latter of which carries both the starter ring gear and the ignition timing mark. The axial portion may have two separate axial sections radially offset relative to each other, with the greater diameter axial section remote from the radial portion and a smaller diameter axial section relatively adjacent to the radial portion.
