Abstract
A trunnion mount for mounting an engine to a chassis. A support element fixedly connected and/or connectable to the engine and having a ring portion with an outer bearing surface that is arranged concentrically around the crankshaft of the engine. A shelf having an inner bearing surface for surrounding the outer bearing surface of the support element. The shelf forming the link between the chassis and the engine. A rubber bearing arranged between the inner bearing surface of the shelf and the outer bearing surface of the support element. The trunnion mount is characterized in that the rubber bearing is axially press-fitted on the outer bearing surface of the support element.
Claims19
A combustion engine comprising a crankshaft and a trunnion mount for mounting the combustion engine to a chassis, the trunnion mount comprising:
- a support element fixedly connected to the engine and having a ring portion with an outer bearing surface that is arranged concentrically around the crankshaft of the combustion engine,
- a shelf having an inner bearing surface for surrounding the outer bearing surface of the support element, the shelf forming a link between the chassis and the combustion engine, and
- a rubber bearing arranged between the inner bearing surface of the shelf and the outer bearing surface of the support element, wherein the rubber bearing comprises an inner metal layer formed by a cylindrical metal sheet,
- wherein the inner metal layer of the rubber bearing formed by the cylindrical metal sheet is axially press-fitted on the outer bearing surface of the support element and contacts the outer bearing surface of the support element around its entire circumference.
A method for mounting a combustion engine to a chassis via a trunnion mount,
- the trunnion mount, comprising:
- a support element fixedly connected and/or connectable to the engine and having a ring portion with an outer bearing surface that is arranged concentrically around the crankshaft of the engine,
- a shelf having an inner bearing surface for surrounding the outer bearing surface of the support element, the shelf forming the link between the chassis and the engine, and
- a rubber bearing arranged between the inner bearing surface of the shelf and the outer bearing surface of the support element, wherein the rubber bearing comprises an inner metal layer formed by a cylindrical metal sheet,
- axially press-fitting the inner metal layer of the rubber bearing formed by the cylindrical metal sheet on the bearing surface of the support element to contact around an entire outer bearing surface of the support element.
An apparatus comprising a chassis and a combustion engine, wherein the combustion engine is connected to the chassis by at least one trunnion mount,
- the at least one trunnion mount, comprising:
- a support element fixedly connected and/or connectable to the combustion engine and having a ring portion with an outer bearing surface that is arranged concentrically around a crankshaft of the combustion engine,
- a shelf having an inner bearing surface for surrounding the outer bearing surface of the support element, the shelf forming the link between the chassis and the engine, and
- a rubber bearing arranged between the inner bearing surface of the shelf and the outer bearing surface of the support element, wherein the rubber bearing comprises an inner metal layer formed by a cylindrical metal sheet,
- wherein the inner metal layer of the rubber bearing formed by the cylindrical metal sheet is axially press-fitted on the outer bearing surface of the support element and forms contact around an entire outer bearing surface of the support element.
