Vibration suppression device of a power train, power train provided therewith and vibration suppression method for a power train

摘要

A heat exchanger (60), which performs heat exchanging between a lubricating oil circulating within a transfer device (20) disposed behind an engine (1) and an engine coolant, also functions as a mass member of a dynamic dumper. The heat exchanger (60) is disposed at an upper face of a transfer case (21) via a resilient member (70). Herein, the resilient member (70) is comprised of a first metal plate (71), a second metal plate (72), and a rubber member (73) interposed between the first and second metal plates (71, 72) and there are provided lubricating passages (70a, 70b, 70c, 70d, 70e) flowing within the resilient member (70). Accordingly, there can be provided the vibration suppression device of the power train that can suppress vibration properly regardless of the temperature changing and advantage the weight reduction without requiring any new disposition space.
