駆動装置
Document Type and Number:
Japanese Patent JP7024664
Kind Code:
B2
Abstract:
To provide a drive unit which can avoid or suppress the generation of the vibration of a chain caused by resonance, and a vibration sound resulting from the vibration.SOLUTION: In a drive unit 1 in which a motor 2 having a power generation function driven by the transmission of engine torque via a chain 24 is arranged at an output side of a flywheel 10 to which the engine torque generated by an engine is transmitted, the flywheel 10 comprises: a recess 12 which is formed while being recessed to a rotation center axial line direction of the flywheel; a vibration mass 13 which is at least partially arranged in the recess 12; and an elastic member 33 for connecting the vibration mass 13 and the recess 12 so as to allow the flywheel 10 and the vibration mass 13 to relatively rotate. By the vibration of the engine torque, the vibration mass 13 vibrates to a circumferential direction of the flywheel 10 with respect to the flywheel 10, and the vibration of the engine torque transmitted to the chain 24 is reduced.SELECTED DRAWING: Figure 1
