Abstract:
A hydraulic torque converter, comprising:a housing including a mass and arranged to rotate about a predetermined axis, to confine a supply of hydraulic fluid and to receive torque from an output element of a prime mover; a pump disposed in and arranged to rotate with said housing about said axis; an annular turbine coaxial with said pump, disposed in said housing and arranged to receive torque from the fluid in said housing in response to rotation of said pump; a rotary input element coaxial with said housing; a rotary output member arranged to transmit torque between said input element and at least one of said pump, said turbine and said housing; a bypass clutch engageable to transmit force between said pump and said turbine during predetermined stages of operation of the torque converter; at least one torsional vibration damper including an input, an output coaxial with said housing and with said input and rotatable relative to said input, energy storing means arranged to oppose rotation of said input and said output relative to each other, and a torque transmitting member between said input and said output element; an annular array of retaining members provided on said mass and received in openings provided therefor in said torque transmitting member; and means for holding said retaining members in the respective openings.
