  • Publication number: 20200248789
    Abstract: A torque converter includes first and second dampers disposed in a torque transmission path during lockup, and a dynamic damper attached to the torque transmission path between the first and second dampers. The dynamic damper includes an inertial rotating body having a weight member mounted on an outer peripheral part of an inertia plate sandwiched between a pair of retaining plates and an elastic member provided between the inertia plate and the retaining plates. A claw part is provided on one of the retaining plates disposed on a side opposite to the clutch constituent member with respect to the inertia plate. The first damper spring is sandwiched between the claw part and the clutch constituent member, and an elongated hole is formed in the inertia plate, the elongated hole extending lengthwise in a peripheral direction of the inertia plate while the claw part is inserted through the elongated hole.

  • Patent number: 10683908
    Abstract: A torque converter is provided in which abutment claw portions provided integrally with one of a pair of retaining plates of a dynamic damper mechanism are inserted into a cutout part, a spring retaining member fixed to a clutch piston having the cutout part, wherein the cutout part is formed so that an inner end of the cutout part along a radial direction of an output shaft is positioned further outside than an inside end of a damper spring in the radial direction, and the abutment claw portion is formed so that part of the abutment claw portion overlaps an inertia plate in a projection onto a plane passing through the abutment claw portion and an axis of the output shaft. Such arrangement shortens the axial distance between the clutch piston and the dynamic damper mechanism while maintaining function of the spring retaining member in retaining the damper spring.
