Title:
ARRANGEMENT STRUCTURE OF ELECTRIC AUTOMOBILE VIBRATION ISOLATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/131509
Kind Code:
A1
Abstract:
[Problem] To provide an arrangement structure of an electric automobile vibration isolating device with which it is possible to suppress a sudden increase in a dynamic spring constant of the electric automobile vibration isolating device when a load equal to or greater than a prescribed range acts on the electric automobile vibration isolating device. [Solution] A through hole penetrating in an axial direction through an inner cylinder member 10 is not formed in a vibration isolating base body 30 in a position overlapping the inner cylinder member 10 in the direction of gravity, in a state in which an electric automobile vibration isolating device 100 is attached to a vehicle body of an automobile, and a characteristic of a load in the direction of gravity with respect to an amount of deflection of the vibration isolating base body 30 within a range of the amount of deflection of up to 30% of the free length of the vibration isolating base body is linear, and it is therefore possible to suppress a sudden increase in the dynamic spring constant when a load within a prescribed range acts on the electric automobile vibration isolating device 100 in the direction of gravity.
