Damper disc assembly
First Claim
1. A damper disc assembly for transmitting power from an engine to an input shaft of a transmission, the damper disc assembly comprising:
- a hub flange to which power from the engine is input, the hub flange having a plurality of openings;
an output hub coupled to the input shaft of the transmission;
a single ring-shaped intermediate hub arranged between the hub flange and the output hub in a radial direction such that relative rotation with the hub flange by an angle greater than or equal to a first angular range is prevented, and such that relative rotation with the output hub by an angle greater than or equal to a second angular range is prevented;
a pair of retaining plates arranged on respective sides in an axial direction of the hub flange and the intermediate hub, the pair of retaining plates coupled to the intermediate hub such that relative rotation with the intermediate hub is prevented;
a plurality of first elastic members arranged in the plurality of openings of the hub flange, the plurality of first elastic members coupling the hub flange and the pair of retaining plates elastically in a rotation direction; and
a plurality of second elastic members that couple the intermediate hub and the output hub elastically in the rotation direction.

Abstract
A clutch disc assembly includes a hub flange, an output hub, an intermediate hub, a plurality of first elastic members, and a plurality of second elastic members. Power from an engine is input into the hub flange. The output hub can be coupled to an input shaft of the transmission. The intermediate hub is arranged between the hub flange and the output hub in a diameter direction such that relative rotation with the hub flange by an angle greater than or equal to a first angular range is prevented, and such that relative rotation with the output hub by an angle greater than or equal to a second angular range is prevented. The plurality of first elastic members couple the hub flange and the intermediate hub elastically in a rotation direction. The plurality of second elastic members couple the intermediate hub and the output hub elastically in the rotation direction.
