Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2018/155357
Kind Code:
Provided is a torque converter in which first and second dampers are interposed in a torque transmission path during lock-up and a dynamic damper is attached to the torque transmission path between the first and second dampers, wherein a dynamic damper (49) comprises: an inertial rotating body (41) formed by attaching a weight member (62) to the outer periphery of an inertial plate (61) that is sandwiched between a pair of retaining plates (50, 51); and an elastic member (58) that is provided between the inertial plate and the retaining plates. A claw part (68) that holds a first damper spring (55) between itself and a clutch constituent member (43) is provided to the retaining plate (50) that is disposed on the side opposite the clutch constituent member relative to the inertial plate, and an elongated hole (69), which extends in the peripheral direction of the inertial plate and into which the claw part is inserted, is formed in the inertial plate. Due to this configuration, a sufficient inertial mass can be secured and the dynamic damper can be manufactured inexpensively, and the torque converter can be reduced in size in the axial direction.
