Abstract
Official abstract text for this publication.
A damper device includes a damper unit and a torque limiter unit. The damper unit includes a first input plate, a second input plate, a fastening portion fastening the first and second input plates, an output plate, and an elastic member elastically connecting the output plate and the first and second input plates. The torque limiter unit includes a first side plate, a second side plate, a friction plate, and a first friction material disposed between the friction plate and the first side plate. The first input plate includes an outer peripheral end disposed on a first side of an inner peripheral end of the first side plate in an axial direction. The first input plate has an outer diameter greater than an inner diameter of the first side plate. The fastening portion is disposed on the first side of the first side plate in the axial direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A damper device configured to be attached to a power source-side member on a first side of the power source-side member in an axial direction, the damper device comprising: a damper unit; and a torque limiter unit configured to be attached to the power source-side member, wherein the damper unit includes a first input plate, a second input plate disposed on a second side of the first input plate in the axial direction, the second input plate configured to rotate unitarily with the first input plate, a fastening portion fastening the first and second input plates, an output plate, and an elastic member configured to elastically connect the output plate and the first and second input plates, the torque limiter unit includes a first side plate having an annular shape, a second side plate having an annular shape, the second side plate disposed on the second side of the first side plate in the axial direction, the second side plate disposed apart from the first side plate at an interval in the axial direction, a friction plate configured to rotate unitarily with the first and second input plates, and a first friction material disposed between the friction plate and the first side plate, the first input plate includes an outer peripheral end disposed on the first side of an inner peripheral end of the first side plate in the axial direction, the first input plate has an outer diameter greater than an inner diameter of the first side plate, and the fastening portion is disposed on the first side of the first side plate in the axial direction and to overlap with the first side plate as seen in the axial direction. 2. The damper device according to claim 1 , wherein the output plate is disposed on the first side of the first side plate in the axial direction. 3. The damper device according to claim 1 , wherein the friction plate is disposed on the second side of the second input plate in the axial direction. 4. The damper device according to claim 1 , wherein the first input plate includes a first plate body and a first attachment portion protruding radially outward from the first plate body, and the fastening portion fastens the first attachment portion and the second input plate. 5. A damper device configured to be attached to a power source-side member on a first side of the power source-side member in an axial direction, the damper device comprising: a damper unit; and a torque limiter unit configured to be attached to the power source-side member, wherein the damper unit includes a first input plate including a first plate body and a first attachment portion protruding radially outward from the first plate body, a second input plate disposed on a second side of the first input plate in the axial direction, the second input plate configured to rotate unitarily with the first input plate, a fastening portion, an output plate, and an elastic member configured to elastically connect the output plate and the first and second input plates, the torque limiter unit includes a first side plate having an annular shape, a second side plate having an annular shape, the second side plate disposed on the second side of the first side plate in the axial direction, the second side plate disposed apart from the first side plate at an interval in the axial direction, a friction plate configured to rotate unitarily with the first and second input plates, and a first friction material disposed between the friction plate and the first side plate, the first input plate includes an outer peripheral end disposed on the first side of an inner peripheral end of the first side plate in the axial direction, the first input plate has an outer diameter greater than an inner diameter of the first side plate, and the fastening portion is disposed on the first side of the first side plate in the axial direction, the second input plate including a second plate body, an extending portion, and a second attachment portion, the extending portion extending from the second plate body to the first side in the axial direction, the second attachment portion extending radially outward from the extending portion, and the fastening portion fastens the first attachment portion and the second attachment portion. 6. The damper device according to claim 5 , wherein the output plate is disposed on the first side of the first side plate in the axial direction. 7. The damper device according to claim 5 , wherein the friction plate is disposed on the second side of the second input plate in the axial direction.
