Mechanical/fluid actuated slider clutch

An improved combined mechanical and fluid pressure actuated slider clutch for a motorcycle utilizing an original equipment manufacturers motorcycle transmission output shaft, front bearing, transmission gear cluster main bearing assembly, thrust washer, center hub and a plurality of nested clutch friction discs and plates, also an after-market slider basket, a spring loaded housing gear assembly having the main bearing assembly joined into the housing gear forming a rotational bearing receptacle and a pressure plate contiguous with the friction discs, urging the discs together during torque transmitting actuation, the improvement comprising:

• (a) a slider basket enclosure joined to the slider basket enveloping the pressure plate while allowing the pressure plate to move and be in contact with the friction discs and plates when urged thereupon;
• (b) a plurality of offset fingers pivotally attached to the slider basket enclosure allowing intimate contact with the pressure plate urgingly forcing the pressure plate into contact with the friction discs and plates to compress together unitedly joining the slider basket with the center hub making union between the spring loaded housing gear assembly and transmission gear cluster main gear assembly transmitting torque without completely locking-up providing a first mechanical stage of actuation;
• (c) a plurality of counterbalanced fingers pivotally attached to the slider basket enclosure providing the same functional operation as the offset fingers when allowed pivotal rotation permitting a fluid pressure actuated second stage of operation;
• (d) an enclosure bearing pressed into the basket enclosure on a surface opposite the interface with the slider basket and parallel thereunto;
• (e) a clutch housing case having a projecting boss on a first side and a second side defining a hollow cylinder, the boss pressed into the enclosure bearing allowing the slider basket and enclosure to be further supported and revolve freely when rotated externally;
• (f) restraining means contained within the basket enclosure and housing case suppressing the force created by a camming action of the counterbalanced fingers allowing unobstructed first mechanical stage of actuation to be accomplished by the offset fingers;
• (g) fluid pressure actuating means integral with the restraining means allowing a gradual predetermined release of constraints imposed by the restraining means permitting the counterbalanced fingers to urgingly force the pressure plate into further contact with the friction discs and plates such that torque on the output shaft does not overcome motorcycle coefficient of friction;
• and,
• (h) timing control means in communication with the fluid pressure actuating means providing predetermined timed sequential release of the restraining means.
