Abstract
A power transmission device includes a flywheel, a torque limiter unit, and a damper unit. The torque limiter unit includes first and second side plates and a friction plate. The first side plate is attached to the flywheel. The first side plate is disposed on a first axial side to the flywheel. The friction plate is disposed axially between the first side plate and the second side plate. The damper unit includes input rotational bodies, an output plate, and an elastic member. The output plate is disposed axially between the first side plate and the flywheel.
Claims8
A power transmission device, comprising:
- a flywheel;
- a torque limiter unit attached to the flywheel;
- and
- a damper unit attached to the torque limiter unit,
- wherein the torque limiter unit includes
- a first side plate attached to the flywheel and disposed on a first axial side with respect to the flywheel;
- a second side plate configured to rotate integrally with the first side plate and disposed on a second axial side with respect to the first side plate;
- and
- a friction plate disposed axially between the first side plate and the second side plate, and
- the damper unit includes
- an input rotational body configured to rotate integrally with the friction plate;
- an output plate disposed axially between the first side plate and the flywheel, the output plate disposed to be rotatable relative to the input rotational body, and
- an elastic member elastically coupling the input rotational body and the output plate.
