Abstract:
An automatic operating apparatus for a friction clutch, comprisinga motor rotatable forward and backward;a reduction means for reducing the rotation of said motor;a movement conversion means converting the rotation of said motor into the axial movement of a piston rod of a hydraulic master cylinder so as to disconnect the frictional clutch;a load accumulating means provided on the housing of the apparatus so as to accumulate the loads due to the rotating force of said motor;a link mechanism provided on said piston rod so as to accumulate said load in said load accumulating means when said motor is rotated backward to connect said clutch and so as to release the accumulated load when said motor is rotated forward; andsaid link mechanism forming a toggle joint comprising a crank arm as an output part of said reduction means, said piston rod, a link rotatably connected with said load accumulating means through a first connecting portion, and a second connecting portion for connecting said, crank arm, said piston rod and said link to be mutually rotatable;said crank arm and said link being positioned on a straight line, and said piston rod extending substantially perpendicular to the straight line, when the clutch is in a midway condition between connection and disconnection.
