Abstract
A clutch device configured for a transmission may include a first body and a second coaxially mounted to the first body; a friction element mounted between the first body and the second body; a friction piston configured to axially press the friction element by use of hydraulic pressure; a retractable mechanism including a dog clutch, which is configured to restrict rotation between the first body and the second body, and repeatedly engaging and disengaging the dog clutch by repeatedly applying pressure in axial direction thereof; and an operation piston configured to provide pressure to the retractable mechanism in an axial direction of the retractable mechanism.
Claims20
A clutch device for a transmission, the clutch device comprising:
- a first body and a second body coaxially mounted to the first body;
- a friction element mounted between the first body and the second body;
- a friction piston configured to in an axial direction press the friction element by use of hydraulic pressure;
- a retractable mechanism including a dog clutch, which is configured to restrict rotation between the first body and the second body, and configured so that, by repetition of release after application of pressure along the axial direction, at one time the dog clutch establishes an engaged state and at the other time, the dog clutch establishes a disengaged state;
- an operation piston configured to provide pressure to the retractable mechanism in the axial direction of the retractable mechanism.
A clutch device configured for a transmission, the clutch device comprising:
- a first body and a second body coaxially mounted outside of the first body;
- a friction element configured to generate friction between the first body and the second body;
- a friction piston configured to increase friction of the friction piston by applying pressure to the friction element;
- and
- a restriction maintainer configured to restrict relative rotation of the first body and the second body after pressure applied to the friction element by the friction piston is removed,
- wherein the restriction maintainer includes:
- a retractable mechanism including a dog clutch, which is configured to restrict relative rotation of the first body and the second body, and configured so that, by repetition of release after application of pressure along an axial direction, at one time the dog clutch establishes an engaged state and at the other time, the dog clutch establishes a disengaged state;
- and
- an operation piston configured to provide pressure to the retractable mechanism in the axial direction of the retractable mechanism.
