An intermediate member of a damper device includes a plate portion that has spring abutment portions that abut against inner springs. Spring abutment portions of a coupling member of a dynamic damper extend from a fixed portion via a bent portion to be disposed in opening portions of the plate portion, and abut against end portions of third springs disposed in the opening portions such that the third springs are arranged side by side with the inner springs in the circumferential direction. The plate portion and the spring abutment portions at least partially overlap each other in the thickness direction. The axes of the inner springs and the third springs are included within the range of overlap between the plate portion and the spring abutment portions in the thickness direction.

A damper assembly for a torque converter is provided. The damper assembly includes a spring retainer including an interior space configured for holding springs and a spring support plate fixed to the spring retainer to define an inlet gap between a first section of an outer circumference of the spring support plate and the spring retainer for insertion of one of the springs. The outer circumference of the spring support plate further includes a second section circumferentially offset from the first section. The second section is arranged and configured with respect to spring retainer for axially holding the plurality of springs in the interior space during operation of the damper assembly. A torque converter and a method of forming a damper assembly for a torque converter are also provided.

A clutch arrangement is provided with a mass damper system having a damper mass carrier and damper masses deflectable relative to the damper mass carrier. The clutch arrangement has a housing having at least two housing parts permanently connected to one another by a fixed connection, at least one housing parts has a cutout for at least one projection of the other housing part. The housing parts are assembled while receiving the damper mass carrier between an axial stop of the cutout of the one housing part and the projection of the other housing part. The housing parts are loaded over the course of producing the fixed connection by a clamping mechanism which acts on the housing parts in direction away from one another and operative axially between one of the housing parts and the damper mass carrier axially supported at the other respective housing part.

A transmission damper includes a first cover plate, a flange, a spring, and a shaft. The first cover plate includes a first spring window and is arranged for fixing to a sheave for a continuously variable transmission. The flange is rotatable relative to the first cover plate and includes a second spring window. The spring is disposed in the first and second spring windows. The shaft is fixed to an inner portion of the flange and arranged for connecting to an engine crankshaft. In an example embodiment, the shaft is fixed to the flange by welding. In an example embodiment, the sheave is rotatable relative to the shaft. In an example embodiment, the shaft includes an internal taper for connecting to the engine crankshaft. In an example embodiment, the flange includes a radially extending tab arranged for contacting a portion of the cover plate after a predetermined rotation.
