Abstract
An output shaft of an internal combustion engine and an input shaft of a transmission are coupled to each other via a damper device. The damper device includes a housing and a rotary member that rotate relative to each other to damp the torsional vibration of the output shaft, and transmits the rotational force of the output shaft to the input shaft and damps the torsional vibration of the output shaft. The rotary member is fitted to a hub from outside. The output shaft is fixed via a flywheel to the housing for rotation together therewith, while the input shaft is fitted in a fitting hole formed in the hub.
Claims8
A power transmission device for a vehicle, comprising:
- a damper device that couples an output shaft of an internal combustion engine and an input shaft of a transmission to transmit a rotational force of the output shaft to the input shaft and that damps torsional vibration of the output shaft, wherein the damper device includes a first rotary member and a second rotary member that rotate relative to each other to damp the torsional vibration, and one of the output shaft and the input shaft is fixed to the first rotary member for rotation together therewith while the other is fitted in a fitting hole formed in the second rotary member.
A method of producing a power transmission device for a vehicle, the power transmission device including a damper device that couples an output shaft of an internal combustion engine and an input shaft of a transmission to transmit a rotational force of the output shaft to the input shaft and that damps torsional vibration of the output shaft, the method comprising:
- connecting a first rotary member and a second rotary member, which rotate relative to each other to damp the torsional vibration, to the damper device;
- fitting one of the output shaft and the input shaft into a fitting hole formed in the second rotary member;
- and
- fixing the other of the output shaft and the input shaft to the first rotary member for rotation together therewith after the fitting of one of the output shaft and the input shaft.
