Abstract: An engine assembly may include an internal combustion engine and an expander couplable to the internal combustion engine in a force transmitting manner. The engine assembly may also include a pulley mounted rotatably on a shaft of the expander. The pulley may be coupled to the internal combustion engine in a force-transmitting manner via a belt drive. The engine assembly may further include a first driver plate connected non-rotatably to the pulley and a second driver plate arranged adjacent thereto and connected non-rotatably to the shaft. The engine assembly may additionally include a clutch device including at least one actuating device and a coupling wheel. The coupling wheel may contact the first driver plate and the second driver plate when the clutch device is closed such that the pulley is connected with the shaft of the expander in a driving manner.

Abstract: An engine assembly may include an internal combustion engine, an expander coupled to the engine, a pulley rotatably arranged on a shaft of the expander and coupled to the engine, a coupling device including at least one elastic operating element arranged within an operating element accommodation in an axially deformable manner, a drive disk arranged on the shaft between the pulley and the at least one operating element, and a pressure device connected to the operating element accommodation via a fluid line and configured to apply pressure to the operating element accommodation. The at least one operating element may be deformable in an axial direction such that the at least one operating element adjusts the drive disk into force-transferring contact with the pulley when the at least one operating element is deformed by a pressure applied to the operating element accommodation by the pressure device.
