Abstract: Proposed is a transmission mount for a vehicle in which the structure of an upper insert and a lower insert integrated with a single bridge among components of the transmission mount is improved to reduce the static stiffness in the right-left direction (i.e., the Y direction) of the transmission mount. The strength of the transmission mount in the front-rear direction (i.e., the X direction) and the static stiffness in the top-bottom direction (i.e., the Z direction) is reinforced so that the pitching motion and the vertical bounce behavior of the transmission may be efficiently controlled. Accordingly, booming noise caused by the rolling motion of the transmission is minimized, thereby improving NVH performance and meeting driving performance.
