Abstract:
A torque transmission apparatus for transmitting torque from a driving source to a rotating device, the apparatus comprising:a first rotating member, wherein the first rotating member has a dual tubular form and includes an inner tube and an outer tube, which are coaxial, and the outer tube is connected to one of the driving source and the rotating device; a bearing arranged within the inner tube, wherein the bearing supports the first rotating member in a rotatable manner; a second rotating member, which is coaxial to the first rotating member, and the second rotating member is connected to the other of the driving source and the rotating device; an elastically deformable torque transmission member arranged between the inner tube and the outer tube, for transmitting the torque between the first rotating member and the second rotating member; and a pendulum type vibration-absorbing mechanism located between the inner tube and the outer tube, for canceling an exciting force generated by rotational movement of the rotating members, wherein the mechanism includes a movable weight.
