ABSTRACT:
A mounting scheme for attaching a power train to a motor vehicle frame includes a plurality of mounts. At least one of the mounts is a solid engine mount having a metal housing and an elastomeric bushing. The elastomeric bushing contains no voids other than a central bore used to attach the mount to a bracket. The elastomeric bushing includes frustoconical portions, where one end of each of the frustoconical portions is unconstrained by the metal housing. The stiffness of the mount may be tuned to reduce noise and improve handling. The stiffnesses of any of the axes may be adjusted so that the power train roll center aligns with the power train center of gravity.
