Patent ID: 8499902

Claim:
A braking apparatus for implements of motor-driven tool units, the braking apparatus comprising: an arm having at least one bearing disposed therein for rotatable mounting of an axle, a first friction element being firmly connected on the arm; and a flange fastened on the rotatably mounted axle, the axle and/or the flange being drivable by means of a drive motor, a second friction element being connected to the axle and/or to the flange and being displaceable relative to the axle, the second friction element comprising two brake shoes which each have a throughbore approximately centrally through which the axle can be guided, each brake shoe having a friction surface on one side and a flyweight on the opposite side in relation to the throughbore, the two friction surfaces of the brake shoes lying opposite to one another relative to the axle; wherein the first and the second friction element come into frictional contact with one another or not depending on the action of centrifugal force on the flyweights.
