Mount assembly for automotive power plant

A power plant mounting structure for a vehicle including an engine-side mount assembly, a transmission-side mount assembly, and front and rear mount assemblies, wherein the engine-side mount assembly comprises;

• a mount which is less stiff in front and rear directions than in upward and downward directions of the vehicle, and wherein the mount is arranged such that an axis of the mount is parallel to an inertial axis of a moment of inertia of the power plant;
• a linkage member for connecting the mount to an engine-side of the power plant by coupling a screw member coaxially fixed at the center of the mount with a screw block fixed to the engine-side of the power plant;
• a mounting bracket for fixing the mount to a side member of the vehicle body;
• and
• means for enhancing rigidity of the mount assembly in left and right directions of the vehicle relative to a longitudinal axis of the vehicle, wherein the enhancing means is formed by bending the longer edges of a steel strip, and one end of the enhancing means is fixed on a top portion of the mount and another end of the enhancing means is fixed to an apron panel of the vehicle body.
