Clutch lever for racing car

摘要

A clutch lever for a centrifugal clutch applies axial pressure on one or more clutch disc assemblies as a function of the rotational speed of the engine. The clutch levers are formed with two pieces when joined together form a joint that opposes the shear force exerted on the contact surface when the clutch lever is applying axial forces against the clutch disc assemblies. One piece is formed as a replaceable nose piece or contact surface portion which obviates the need to replace the entire clutch lever when one becomes damaged. The other piece is complementary and is configured to be pivotably mounted with respect to the pressure plate, When the nose piece portion breaks, only one piece of the clutch lever needs to be replaced.

主权项

1. A clutch lever for applying an axial clamping force to a clutch assembly portion of a centrifugal clutch as a function of a centrifugal force applied to the clutch lever, the clutch lever comprising:
a lever portion, said lever portion having (i) a first aperture adapted to enable said lever portion to be pivotally mounted with respect a pressure plate that forms a portion of said clutch assembly, and (ii) a first mating surface,
wherein the lever portion is configured to pivot about a pivot axis; and a replaceable nose piece portion, said replaceable nose piece portion having a second mating surface,
wherein said second mating surface is (i) complementary to said first mating surface, and (ii) configured to form a joint with said first mating surface that enables said replaceable nose piece portion to slideably engage said lever portion in a direction substantially parallel to the pivot axis,wherein said lever portion and said replaceable nose piece portion slideably engage to form a single clutch lever for use in a said clutch assembly.
