Abstract
A clutch assembly for a motor vehicle includes a retainer assembly having an upper and lower portion separable by a separating member. The separable member causes the retainer assembly to contract in response to movement toward a released position. Contracting the retainer assembly in the release position provides for additional clearance between the friction discs and flywheel without a corresponding increase in the length of travel of the retainer assembly. The guide member is stationary relative to the retainer assembly and cooperates with the separating member to cause the retainer assembly to expand and contract during movement to engage and disengage the clutch. Additional movement of the retainer assembly increases clearance to between the flywheel and friction discs without corresponding increase in retainer assembly travel to minimize clutch drag.
