Title:
TORQUE CONVERTER
Document Type and Number:
WIPO Patent Application WO/2017/175557
Kind Code:
A1
Abstract:
Provided is a torque converter wherein contact protrusions provided integrally to one of a pair of holding plates which constitute portions of a dynamic damper mechanism are inserted through the cutouts of a spring holding member affixed to a clutch piston. The cutouts (70) are formed such that the inner ends (70a) of the cutouts (70) extending in the radial direction of an output shaft (27) are located on the outside, in the radial direction, of the inner ends (49a) of damper springs (49). The contact protrusions (54b) are each formed such that a part of the contact protrusion (54b) overlaps an inertia plate (58) in a view projected on a plane passing through the contact protrusion (54b) and the axis of the output shaft (27). As a result, the axial distance between the clutch piston and the dynamic damper mechanism can be reduced while the damper spring holding function of the spring holding member is maintained.
