Abstract
An engine mounting arrangement includes elastomeric mounting blocks interposed between laterally extending arms connected to the engine and brackets fixed to a cross member of the chassis near the outboard ends thereof. The blocks are adapted to undergo shear upon the engine rolling about an essentially longitudinal axis. The arrangement further includes a mounting unit including an elastomeric chamber defining member which readily undergoes shear without changing the volume the chamber which it defines when the engine rolls but which undergoes a volume change upon the engine bouncing or vibrating in the vertical direction. The volume change pumps working fluid from the chamber to a second variable volume chamber and vice versa through a flow restriction so that vertical movement of the engine is strongly damped but rolling readily permitted. The arrangement further minimizes the transmission of vibration from the engine to the chassis and the tendency of the cross member per se to be vibrated.
