20080308380 | APPARATUS AND SYSTEM FOR AUTOMATIC CENTRIFUGAL ENGAGEMENT OF A PRESSURE PLATE - 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. | 12-18-2008 |
20090211872 | APPARATUS AND SYSTEM FOR A TORQUE RESPONSIVE CLUTCH - An improved apparatus for varying the pressure applied to a clutch system that can be used to couple a rotational input with a rotational output. Depending on the load and direction of torque in the clutch system, the improved apparatus will engage a spring with more force or less force to affect the amount of torque transferred by the clutch system and the force required by an operator to manually disengage the clutch system. | 08-27-2009 |
20130168198 | WEAR LINER AND IMPROVED FRICTION DISKS FOR USE IN A STANDARD CLUTCH BASKET - An improved liner and friction disk for a clutch basket is disclosed. The improved liner is easily retrofitted into a typical clutch basket and is held in place without fasteners or adhesives or special changes to the clutch basket. The improved liner is held in place without consideration to the outer diameter of the basket allowing the liner to work with a wider range of clutch basket designs and sizes. The liner provides an improved wear surface for the clutch basket's engagement surface with the driving friction surface. A friction disk with tabs adapted to fit inside the narrowed space provided by the improved liner is also disclosed. | 07-04-2013 |
20130334003 | ADJUSTABLE HYDRAULIC SLAVE CYLINDER FOR CLUTCH INCORPORATING A SPRING BIASED PRESSURE PLATE - A novel adjustable slave cylinder is disclosed. The improved slave cylinder is particularly well suited for use with a clutch incorporating an expanding friction disk. The adjustable slave cylinder provides a means for adjusting a clutch pressure plate's position via an adjustment mechanism external to the inside of an engine. | 12-19-2013 |
20140102847 | EXTERNAL ADJUSTER FOR CLUTCH INCORPORATING AN EXPANDING FRICTION DISK - 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. | 04-17-2014 |
20140166427 | CLUTCH SEPARATOR PLATE - A novel clutch separator plate is disclosed. The improved clutch separator plate incorporates openings which pass over the friction pads of a friction plate to improved thermal stability, reduce drag and provide consistent and positive engagement. | 06-19-2014 |
20150152923 | FRICTION PLATE DESIGN FOR MULTI-PLATE WET FRICTION CLUTCH - An improved friction plate is disclosed. The friction plate incorporates friction pads having substantially V Shaped Grooves having an angle offset to the axis of rotation to improve oil flow characteristics to the center of the friction plate to reduce parasitic drag when the clutch system is in a disengaged state. The improved friction pad design optionally incorporates a V shaped groove extending to the tab portion of the friction plate to improve the capture of oil as the friction plate rotates through an oil bath. | 06-04-2015 |
20150292569 | CLUTCH PACK WITH WEAR LINERS - An improved clutch pack is disclosed. The clutch pack incorporates liners, improved driving friction disks and driven disks where the thickness of the improved driving friction disks and driven disks are selected in order to allow more driving friction disks and more driven disks to be used within the improved clutch pack while maintaining approximately the same overall height as compared to the standard clutch pack the vehicles clutch system was designed for. | 10-15-2015 |
