| 摘要 |
The invention relates to a dual clutch device which prevents the occurrence of a double meshing of a transmission. A dual clutch device includes a first piston (23) which applies a first clutch (C1) by means of a hydraulic pressure supplied into a first hydraulic pressure chamber (25A) and releases the first clutch by a first spring (26), a second piston (33) which applies a second clutch (C2) by means of a hydraulic pressure supplied into a second hydraulic pressure chamber (35A) and releases the second clutch by a second spring (36), a first supply line (43, 50) for supplying a hydraulic pressure into the first hydraulic pressure chamber and a second hydraulic pressure canceling chamber (35B) ,a second supply line (45, 51) for supplying a hydraulic pressure into the second hydraulic pressure chamber and a first hydraulic pressure canceling chamber (25B), a first opening-closing valve (60) which allows or cuts off the supply of hydraulic pressure into the first hydraulic pressure chamber and the second hydraulic pressure canceling chamber, and a second opening-closing valve (65) which allows or cuts off the supply of hydraulic pressure into the second hydraulic pressure chamber and the first hydraulic pressure canceling chamber. |
