Abstract: A vibration isolator assembly, such as a vehicle drive train mount, incorporates a heat shield which protects the elastomeric parts of the isolator assembly from high temperature radiation which could degrade the elastomeric parts.

Abstract: The present invention provides a mounting fixture for mounting a vehicle body to a support member or vehicle frame. The mounting fixture includes an upper and a lower assembly attached to either side of a non-circular aperture in the frame member. Each of the upper and lower assemblies includes an elongated tubular member and a flange portion extending therefrom wherein the lower tubular member is received in telescoping relationship within the upper tubular member. Upper and lower cushioning members are positioned over the upper and lower tubular members and between the flanges and the frame member to provide a cushion between the frame and the vehicle body. The upper cushioning member includes a non-circular extension corresponding to the shape of the aperture in the vehicle frame whereby relative rotation between the upper cushioning member and the vehicle frame is prevented.

Abstract: An isolating mount for connecting two parts or mechanisms includes a rigid bushing surrounded by a resilient block which includes closed cavities on opposite sides of said bushing located along a first plane parallel to the longitudinal axis of said bushing and a passage formed by pipes extending outside the mount between the cavities. A quantity of liquid fills the cavities and passage, providing a liquid column of predetermined inertia in the passage between the cavities for controlling the frequency and amplitude of forces transmitted through the bushing to provide tuning of the damping characteristics of the mount to preselected frequencies of vibration. A rigid outer body surrounds and contacts the block and exerts compressive force thereon substantially along the first plane. The bushing is connected to one of the two parts to be isolated and the outer body is connected to the other of the two parts.

Abstract: An isolating mount, such as for an engine, comprises a rigid bushing with a resilient rubber block molded around it and cavities formed in the block opening to its exterior on opposite sides of the bushing, preferably located along a plane parallel to the longitudinal axis of the bushing. End plates are bonded to the block surrounding the open ends of the cavities, and these plates may have flanges thereon coated with rubber. Optional floor plates may be incorporated in the block at the bottoms of one or both cavities. Covers are held in sealed relation over the cavities, as by forming the flanges around the covers to retain them. A passage is formed between the cavities, and the cavities and passage are filled with a liquid which is confined therewithin. Displacement of the block in response to forces acting on the mount will result in distortion of the cavities and corresponding displacement of the liquid from one of the cavities to the other to damp motion of the block.
