A clutch apparatus is disclosed having concentrically spaced inner and outer clutches. The inner and outer clutches are coupled for rotation via a coupling ring. The present invention is well suited to a configuration wherein one of the clutches is dynamically actuated and one of the clutches is manually disengageable by the operator using a clutch lever. In this configuration, the operation of the clutch lever by the operator is unaffected by the dynamically actuated clutch. The concentric configuration of the clutches is beneficial in allowing the improved clutch to occupy a similar space compared to a traditional clutch mechanism.

Clutch apparatus employing dual concentric clutches

An adjuster is disclosed, to be placed 'in-line' to a clutch disengagement system. The adjuster provides a means for lifting the pressure plate above the clutch pack without significantly affecting the operation or feel of the clutch disengagement system to the operator. Such an adjuster is particularly well suited for use with an automatic centrifugal clutch incorporating a friction disk that expands when rotated above a threshold speed.

External adjuster for clutch incorporating an expanding friction disk

An apparatus and system are disclosed for automatic centrifugal engagement of a pressure plate. The apparatus includes a center clutch coupled rotationally with a transmission input shaft, a clutch basket coupled rotationally with an engine output shaft, and a clutch pack disposed between the center clutch and the clutch basked. The clutch pack includes a plurality of drive plates rotationally coupled to the center clutch and a plurality of friction plates rotationally coupled with the clutch basket. The apparatus also includes a pressure plate assembly that is spring-loaded and disposed between the center clutch and the clutch basket. The pressure plate assembly comprises a pressure plate, a spring plate, and a spring disposed between the pressure plate and the spring plate. The system includes the apparatus and a manual override capable of use with cable actuated and hydraulic actuated clutch levers.

Apparatus and system for automatic centrifugal engagement of a pressure plate

An apparatus and system are disclosed for automatic centrifugal engagement of a clutch incorporating a friction disk that expands when rotated above a threshold speed. The apparatus may include a clutch basket, a clutch pack capable of coupling the clutch basket with a center clutch, a pressure plate that may be easily adjusted to create a gap between the pressure plate and the clutch pack and an expanding friction disk assembly that may take the place of one or more friction disks. The assembly expands under centrifugal force to provide automatic engagement of the clutch. A mechanism is provided to manually override the automatic engagement of the clutch with a clutch lever and with improved operational performance of the clutch lever versus previous automatic clutch systems.

Automatic clutch employing expanding friction disk and an adjustable pressure plate

An apparatus and system are disclosed for automatic centrifugal engagement of a pressure plate. The apparatus includes a clutch basket, a clutch pack capable of coupling the clutch basket with a center clutch, a pressure plate axially moveable toward the clutch pack, and a top plate coupled to a rotating hub. The rotating hub is configured to pass through an opening in the pressure plate. The apparatus also includes at least one centrifugal actuating member disposed between the pressure plate and the top plate, and at least one spring disposed between the rotating hub and the center clutch to bias the pressure plate relative to the top plate. The system includes the apparatus and a rotating hub lifter coupled with the rotating hub and configured to position the rotating hub in one of a manual clutch mode position and an automatic clutch mode position.
