ABSTRACT:
A torque converter has a housing for an input shaft and output shaft drivenly connected to one another with friction elements rotatably mounted on arms on pivotable holders. The holders are interconnected by the members so that rotation of the input shaft rotates its holder and, via the tie members, the output holder. The friction elements are thus flung outwardly into contact with annular control members within the housing on which they roll. The friction elements also abut and roll on one another, so that at least a major proportion of axial forces on the friction element in operation are held in equilibrium by the elements themselves. Rotation of the friction elements is transferred to the output shaft by planetary gearing on a common axis for the input and output shafts and on the rotation axes of the elements. The transmission ratio is varied by moving a control member towards and away from a second control member which changes the circumference of the path over which the elements roll. The holder is displaceable axially to accommodate this adjustment and maintain the friction elements in contact with one another. The geometrical configuration and disposition of the friction elements are arranged to support one another and mitigate load on their supporting parts.
