POWER TRANSMISSION APPARATUS

摘要

A power transmission apparatus includes a first rotation member connected to a first rotation shaft, a second rotation member connected to a second rotation shaft, a third rotation member provided between the first rotation member and the second rotation member, a damper portion provided between the first rotation member and the third rotation member to absorb a torque fluctuation between the first rotation shaft and the second rotation shaft, a torque limiter portion arranged between the second rotation member and the third rotation member to transmit a torque equal to or smaller than a predetermined value, the torque limiter portion restricting a torque transmitted between the second rotation member and the third rotation member from exceeding the predetermined value in a case where a torque greater than the predetermined value is input to the torque limiter portion, and a dynamic vibration absorber provided at the second rotation member.
