Title:
CONICAL CLUTCH DEVICE FOR AUTOMATIC TRANSMISSION
Document Type and Number:
Japanese Patent JP3294422
Kind Code:
B2
Abstract:
PURPOSE: To perform constant regulation of rotation in a given direction and selective regulation of opposite rotation by providing an annular first member having a conical friction surface, an annular second member engageable with the annular first member, and an actuator reinforcing engagement between the two annular members.
CONSTITUTION: When an oil pressure is not fed to a pressure chamber 14, a press force is not exerted on an inner ring 7 from a piston 12 by a return spring 13 and rotation torque of a planetary carrier 1 is transmitted to the inner ring 7 through a second friction surface 7a engaged with the first friction surface 4c of an intermediate member 4 and further to an outer ring 8 through a helical spline 9. During normal rotation of the carrier 1, the intermediate member 4 is nipped between the friction surface 7a and the nip friction surface 8a of an outer ring 8 by means of thrust and the carrier 1 is fixed to a case 3. During reversing of the carrier 1, the inner ring 7 is separated away from an intermediate member 4 by means of thrust and the carrier 1 is rotated. When an oil pressure is fed to the pressure chamber 14 by reversing torque of the carrier 1, the carrier 1 is fixed to a case 3.
