PURPOSE:To improve both ride comfortableness and attitude control in a suspension device of a twin car including an ACS-mounted car and a passive- suspension mounted car by setting mount rubber rigidities for both mounted cars to be different from each other. CONSTITUTION:The rigidities of a mount rubber 52 in a suspension device of an ACS mounted car and a mount rubber 64 in a suspension device of a passive suspension mounted car are set to be different from each other. The rigidity of the mount rubber 52 of the ACS mounted car is set to be larger than the rigidity of the mount rubber 64 of the passive suspension mounted car for a first mode. For a second mode, they are set oppositely. In this constitution, when a load is applied from the wheel side at the first mode, vertical displacement of the mount rubber 52 of the ACS mounted car can be small, and the attitude control can be secured. At the second mode, high frequency vibration of the wheel can be absorbed by the mount rubber 52 of the ACS mounted car, and the ride comfortableness can be improved. |
