Title:
CLUTCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/088007
Kind Code:
A1
Abstract:
When an actuator 8 disengages a clutch, a first piston 10 and a third piston 14 move toward a clutch flow channel 5, the volume of a fifth pressure chamber 17 decreases, and hydraulic fluid inside a second sub-flow channel 20 flows into a sub-cylinder 3. As a result, an elastic piston 21 moves toward a first sub-flow channel 19, and hydraulic fluid in the first sub-flow channel 19 flows into a second adjustment chamber 23 of a main cylinder 2 to limit the elastic deformation of the elastic piston 21. Moreover, when a clutch pedal 6 disengages the clutch, a second piston 12 moves toward the clutch flow channel 5 and the hydraulic fluid in the first sub-flow channel 19 flows into the sub-cylinder 3. As a result, the elastic piston 21 undergoes elastic deformation.
