Abstract
A constant lift device for a friction clutch s comprises a lever ( ) pivotally connected to the pressure plate ( ) of the clutch. An abutment ( ) on the lever contacts the clutch cover ( ) during disengagement to limit the lift of the pressure plate ( ). The pivotal position of the lever ( ) relative to the pressure plate is controlled to maintain the lift of the pressure plate ( ) substantially constant over the life of the clutch. The means for controlling the pivotal position of the lever ( ) includes a pin ( ) mounted for sliding movement relative to the pressure plate ( ). The pin ( ) contacts the lever and is inhibited from sliding movement towards the flywheel to prevent pivotal movement of the lever towards the flywheel but is able to slide in a direction away from the flywheel as the clutch wears to adjust the angular position of the lever. Due to the lever ratio the pin ( ) slides by an amount which is less than the amount of wear.
