Abstract

The rotary housing of a hydrokinetic torque converter, which can be utilized in the power train of a motor vehicle—for example, in conjunction with a continuously variable transmission—contains a torque monitoring device which is installed in such a way that it does not take up any, or any appreciable, additional space, especially in the axial direction of the housing. The torque monitoring device can serve to transmit torque between the lockup clutch and the output element of the torque converter. Additional features reside in the provision, configuration and manner of mounting of an auxiliary mass, and in the provision of a member for centering the piston of the lockup clutch in the housing as well as a member for centering the housing on the output element of a prime mover.

Claims6

Dependent claims

A hydrokinetic torque converter comprising a housing rotatable about a predetermined axis and including a driving section;

a rotary pump, a rotary turbine, and a stator disposed in said housing;
an engageable and disengageable lockup clutch provided in said housing and spacedly surrounding said axis;
a torque sensor disposed in said housing between said turbine and said driving section, as seen in the direction of said axis, and radially inwardly of said clutch;
and means for centering said driving section of said housing on a rotary output element of a prime mover, including a substantially plate-like flexible torque transmitting member connectable with the output element of the prime mover, and an annular plate-like torque transmitting connector arranged to transmit torque between said flexible member and said driving section, wherein said connector includes a hub coaxial with said housing and received in a coaxial recess of said output element.
