<p><P>PROBLEM TO BE SOLVED: To provide a clutch control system capable of realizing automatic operations of delicate clutch operations during starting and stopping a vehicle. <P>SOLUTION: A pair of motor-driven worm mechanisms 26 with different worm screw pitches, which move a first piston 25 back and forth by converting the gradient of a worm gear 24 screwed to a worm 23 to the linear motion, are arranged in parallel. An actuator 20 is composed by being equipped with an operating oil pressure-feeding mechanism 33 to push out the operating oil from a third pressure chamber 32, by advancing a third piston 31 against the bounding force of a spring 30 by a second piston 29 to be advanced by the hydraulic pressure of a single second pressure chamber 28 communicating with each first pressure chamber 27 in which each first piston 25 is stored individually. A flow passage is interconnected between the third pressure chamber 32 and a clutch connecting/disconnecting means. Accordingly, it is constituted so that electronic control can be selectively executed to an electric motor 22 of each motor-driven worm mechanism 26 with a controller. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
