The present invention provides a method of bonding suspension components which creates strong and durable bonding layer by using a chemical coating compatible with MCU. The bonding material uses coating materials to form an intermediated property bonding layer. This bonding layer prevents corrosion on the metal suspension components. The coating has the correct chemical activity to chemically bond MCU at the molecular level during the standard curing reaction. The coating provides an intermediated property layer to improve cyclic fatigue bonding performance, and bond effectively during molding and manufacturing operations.

Bonded micro cellular urethane suspension component

An improved hydraulic engine mount includes a main rubber element of one piece construction. The main rubber element includes an upper portion, an intermediate portion, and a lower portion. The lower portion includes an interlocking seal portion. The hydraulic engine mount includes an upper housing and a lower housing. The interlocking seal portion includes an upper protrusion operable to fit within an upper groove of the upper housing to fit together to form a tight locking seal. The upper housing further includes an upper protrusion operable to connect to an upper groove of the main rubber element. The upper groove of the main rubber element is annular and extends around the lower portion of the main rubber element. The lower portion of the main rubber element further includes a generally axially extending second protrusion abutting both the upper housing and the lower housing. The lower housing includes a protrusion abutting a second protrusion of the main rubber element and fitting within a second groove of the main rubber element. A third protrusion of the main rubber element abuts the protrusion of the lower housing, a top plate of an inertia track assembly, and defines the lower section of an upper chamber. Additionally, a sealing bead is molded to the bottom of the main rubber element to seal against the top of the inertia track.
