Patent ID: 7673535

Claim:
A gearwheel set for a transmission with a power-take-off accessory comprising: a first gearwheel, said first gearwheel having a plurality of first identical recesses; a second gearwheel, said second gearwheel having a plurality of second identical recesses; said first gearwheel and said second gearwheel define a reception space for an actuator; said actuator includes (1) a base seated in the plurality of first identical recesses of the first gearwheel and (2) a sliding block seated in the plurality of second identical recesses of the second gearwheel; said plurality of first identical recesses are of substantially elliptical shape and have a major axis (A 1 ) which run in a direction of a radius (R) running radially outward from a center point (M) of the first gearwheel and a width (b 1 ) and length (l 1 ); said plurality of second identical recesses are of substantially elliptical shape and have a width (b 2 ) which is smaller than width (b 1 ) and a length (l 2 ) approximately equal to length (l 1 ); and wherein the actuator is movable between two positions in the reception space relative to the first gearwheel and second gearwheel as a function of centrifugal force resulting from rotation of the gearwheel set.
