Abstract
A motor mount device for an electric vehicle includes an inner pipe disposed along a front-rear direction of the vehicle, an outer pipe disposed coaxially with and around an outside of the inner pipe, and a main damper with a bridge. The bridge defines an upper chamber and a lower chamber between the inner pipe and the outer pipe along the front-rear direction and the main damper is elastically deformable according to a load transmitted through the inner pipe. The device also includes a middle plate disposed between the main damper and the outer pipe and configured to support a load in the front-rear direction transmitted through the inner pipe by compressing the bridge.
