Japanese Patent JPH0819972
Kind Code:
B2
Abstract:
PURPOSE:To improve durability and reliability by inserting into the 1st rotation member the 2nd rotation member which forms a mechanism which connects fluid chambers of a coordinate phase changing their volumes with cam-bodies reciprocating in a diametric direction. CONSTITUTION:A rotor 40 provided with cylindrical holes 42 in confrontation with a cam surface 31 is inserted into a drive-housing 30 fixed to an input shaft and forming the cam surface 31 on its inner perimeter. Oil chambers 60 are formed by inserting in an oil-tight condition into these cylindrical holes 42 driving pistons 50 which have spherical surfaces 50a slide-contacting with the cam surface 31 and reciprocate at a time of the relative rotation of the input and output shafts. Also, oil chambers 60 of a coordinate phase are connected with oil passages 61a, 2 provided with an orifice 62 and a check valve 64. Accordingly, a torque transmission characteristic which is added with a transmission torque element generated by a centrifugal force element is obtained, so a transmitter is compact and restrains the lowering of transmission torque and prevents the occurrence of a collision sound and is inexpensive and can improve reliability.
