Title:
ARRANGEMENT STRUCTURE OF ELECTRIC AUTOMOBILE VIBRATION ISOLATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/131510
Kind Code:
A1
Abstract:
[Problem] To provide an arrangement structure of an electric automobile vibration isolating device with which it is possible to suppress an increase, to or above a prescribed value, in a dynamic spring constant of the electric automobile vibration isolating device. [Solution] Bored portions 233b penetrating in an axis O direction are formed at both outer sides, in a horizontal direction, of an inner cylinder member 10, in a state in which an electric automobile vibration isolating device 200 is arranged in a vehicle body of an automobile. The weight of a vibration isolating base body 230 can thus be reduced, and the natural frequency of the vibration isolating base body 230 can be made higher than the vibration frequency when a drive source is driven. As a result, it is possible to suppress resonance of the vibration isolating base body 230 due to vibrations when the drive source is driven, and to suppress an increase, to or above a prescribed value, in the dynamic spring constant of the electric automobile vibration isolating device 200.
