Engine mount for motor vehicles

An engine is supported on a frame of a motor vehicle by a plurality of engine mounts. At least one of said engine mounts are positioned on a main axis of inertia of the engine, and has substantially equal vertical and lateral static spring rates, a vertical dynamic spring rate greater than the verti...

More Information
Summary:An engine is supported on a frame of a motor vehicle by a plurality of engine mounts. At least one of said engine mounts are positioned on a main axis of inertia of the engine, and has substantially equal vertical and lateral static spring rates, a vertical dynamic spring rate greater than the vertical static spring rate, and a lateral dynamic spring rate between the vertical dynamic and static spring rates. The engine mount is effective in reducing muffled sound in the passenger compartment of the motor vehicle without impairing riding comfort of the motor vehicle. The spring rates are set to the following ratios: Ksz:Ksy:Kdy:Kdz=1.0:1.0:1.3:1.9.
