Title:
HYDRAULIC POWER TRANSMISSION COUPLING
Document Type and Number:
Japanese Patent JP3889573
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a hydraulic power transmission coupling with a plunger cam ring as a torque generating member having improved durability.
SOLUTION: The hydraulic power transmission coupling for transmitting torque corresponding to a difference between the rotational speeds of input and output shafts comprises a housing 8 provided between relatively rotatable input and output shafts and a connected to one shaft for integral rotation with the cam ring 1 having a cam face 9 formed on the inside face, a rotor 12 rotatably stored in the housing to form a plunger chamber 15 in the axial direction, and a plunger 16 to be driven by the cam face during relative rotation of both shafts. The plunger 16 and the cam ring 1 are formed into recessed spherical shapes and a spherical body 52 is provided between the plunger 16 and the cam ring 1.
