Abstract
An embodiment provides a drive train for a medium duty truck. The drive train includes an engine having an engine output member, and a centrifugal clutch. The clutch has a plurality of swing weights and a driving member. The driving member generally defines an axis and is rotatable with the engine output member. The clutch also includes a ramp portion having a generally planar ramped surface portion in selective engagement with at least a portion of the swing weights, and a clutch disk portion for transferring torque from the driving member to a driven member. The clutch is operable between an engaged condition and a disengaged condition. The swing weights are radially moveable with respect to the axis. Radial movement of the swing weights causes axial movement of at least a portion of the clutch between a disengaged position and an engaged position. The swing weights engage only the ramped surface portion when the at least a portion of the clutch is not in the disengaged position.
