POWER TRAIN MOUNT STRUCTURE OF VEHICLE
Document Type and Number:
Japanese Patent JP2019025951
Kind Code:
A
Abstract:
To provide a power train mount structure of a vehicle in which bending rigidity is suppressed from increasing while improving rigidity (roll rigidity) against torsion of a power train-side mount bracket, and a torsion resonance point and a bending resonance point are set in a high-frequency range and a low-frequency range respectively.SOLUTION: The power train mount structure of a vehicle comprises connection parts 50g and 50h in which a power train-side mount bracket 50 comprising a single extending part 50a extending from an upper end of a stepladder-shaped leg member 50d having leg parts 50b and 50c in a longitudinal direction toward outside in a vehicle width direction is connected to a vehicle body-side mount bracket 51 through a mount rubber 53 to be mounted on the extending part 50a and connects the leg parts 50b and 50c in the longitudinal direction, where an intermediate mounting part 50i is provided between the connection parts 50g and 50h and a rigidity deteriorated part 50k against loads in a vehicle width direction is formed adjacently to the intermediate mounting part 50i.SELECTED DRAWING: Figure 16
