Abstract
Abstract An engine mount assembly for resiliently supporting an engine on a frame of a motor vehicle comprising two pairs of resilient pads which are molded at their outer surfaces to the interior of a sleeve and at their inner surfaces define an opening extending longitudinally of the sleeve. A wedge assembly is mounted in the opening interior of the resilient pads and is expandable to simultaneously compress one pair of the resilient pads to increase the spring rate of these pads without changing the spring rate of the other pair of resilient pads.

An engine mount assembly for resiliently supporting an engine on a frame comprising first mounting means including a multisided sleeve having an opening extending therethrough, two pairs of resilient pads mounted in said sleeve opening with the resilient pads in each pair arranged opposite each other, each of said resilient pads having an outer side molded to an inner surface of one of said sleeve sides of said sleeve, said two pairs of resilient pads having inner sides defining a rectangularly shaped opening extending longitudinally of said sleeve, spring rate adjusting means comprising three wedge blocks mounted in and having a shape conforming to and filling said opening interior of said resilient pads with one of said wedge blocks arranged between the other two wedge blocks, said one wedge block having one side contacting the inner side of one of said resilient pads of one of said pairs and another side facing the other resilient pad of said one pair having oppositely inclined ramps extending transverse to said opening interior of said resilient pads, said other wedge blocks each having one side with a ramp mating with one of said ramps on said one wedge block and another side contacting the inner side of the other resilient pad of said one pair so that when said other wedge blocks are forced to move toward each other said one wedge block is forced to move in one direction toward one side of said sleeve to compress said one resilient pad between said one wedge block and said one sleeve side while said other wedge blocks are forced to move in the opposite direction toward another side of said sleeve to compress said other resilient pad between said other wedge blocks and said other sleeve side whereby the spring rate of said one pair of resilient pads is increased without changing the spring rate of the other pair of resilient pads, second mounting means including clamp means for applying a clamping force to force said other wedge blocks together to compress said one pair of resilient pads.
