Abstract

A vehicle vibration reduction device (1) includes an inertial mass body (30) connected to a rotating shaft (13) of a power transmission device (5) capable of transmitting power from the vehicle ( 2) The driving source (4) for driving transmits rotational power to the driving wheel (10); and the switching device (40), which is provided on the power transmission path between the rotating shaft (13) and the inertial mass body (30), can For the first path (42) connecting the rotating shaft (13) and the inertial mass body (30) via the elastic body (41), and connecting the rotating shaft (13) and the inertial mass body (30) without passing through the elastic body (41) The connected second path (43) is switched. Therefore, the vehicle vibration reducing device (1) has the effect of being able to appropriately reduce vibration.

Description

technical field [0001] The present invention relates to a vehicle vibration reducing device. Background technique [0002] As a device mounted on a vehicle to reduce vibration generated in the vehicle, for example, Patent Document 1 discloses a drive system rotation fluctuation reduction device that transmits the output torque of the internal combustion engine to a drive shaft that transmits the output torque of the internal combustion engine to the vehicle. The rotation fluctuation of the drive system of the transmission shaft and the transmission provided on the transmission shaft is reduced. This drive system rotation fluctuation reducing device includes a variable unit that changes the inertia of a transmission shaft, and a control unit that controls the variable unit. In addition, in the drive system rotation variation reducing device, a shock absorber for absorbing fluctuations in output torque is provided on the internal combustion engine side of the transmission sha...
