Abstract
On an outer periphery of a link 30 for connecting a member car body 20 and a bogie car frame 11, vessel is provided and 42 into which particle shaped members 41 are inserted. A rotation vibration generated from a drive system of a running electric motor 14, a transmission apparatus and a shaft coupling is transmitted to the link 30. The vibration energy generated at link 30 is converted to the kinetic energy in response to the collision of the particle-shaped members 41 contained in the vessel 42 so that the vibration at the link 30 is reduced. Accordingly, the propagation of the vibration to a car body can be restrained. The particle-shaped members 41 can be inserted into a cylindrical portion 31 of the link 30. Further, the particle-shaped members 41 can be inserted movably into a column 32. In a railway vehicle having a bogie car, the vibration caused by the unbalance of the drive system can be restrained and the noise in a car accompanied with the vibration can be reduced.
