Resilient mounting device for transversely disposed engine of front-engine front-drive vehicle

摘要

A mounting device for resiliently supporting a transverse engine on a frame in a vehicle which includes a cylindrical resilient mount having an inner sleeve, an outer sleeve disposed around and spaced apart from the inner sleeve so as to form a radial space therebetween, and a resilient member disposed in the radial space and having a first and a second void which are formed on diametrically opposite sides of the inner sleeve such that the voids are located opposite to each other in a first direction diametrically in the resilient mount. The device further includes a linking structure for connecting the resilient mount to the vehicle engine and frame, such that the axis of the resilient mount is parallel to an axis of rolling of the engine which extends transversely in the vehicle. The linking structure holds the resilient mount such that the first direction of the first and second voids coincides with a second direction in which the resilient mount is vibrated upon rolling of the engine about the rolling axis. The resilient member is subject primarily to a compressive stress upon application of a vibrational load in the vertical direction of the vehicle, and subjected primarily to a shearing stress upon application of a vibrational load in the second direction.
