Embodiment Construction

[0026] according to figure 1 and Figure 5 , the engine assembly 1 according to the invention comprises an internal combustion engine 2 and an expander 3 which can be coupled thereto in a direct or indirect force transmission. The expander 3 can thus be embodied, for example, as a so-called axial piston engine. The pulley 5 is thus arranged rotatably on the shaft 4 of the expansion machine 3 , wherein the pulley 5 is force-transmittingly connected to the internal combustion engine 2 via a belt drive not shown, ie directly or indirectly via The drive train of the power transmission is transmitted to the internal combustion engine 2 . The rotatable arrangement of the pulley 5 on the shaft 4 is achieved by means of corresponding rolling bearings 6 which provide for free movement. A drive disc 7 connected to the shaft 4 in a rotationally fixed manner is arranged axially adjacent to the pulley 5 on the shaft 4 . Also provided is a shaft coupling 8 comprising at least one elasti...

Abstract

An engine assembly (1). The engine assembly (1) may include an internal combustion engine (2), an expander (3) coupled to the engine, a pulley (5) rotatably arranged on a shaft (4) of the expander (3)and coupled to the engine (2), a drive disk (7) arranged on the shaft (4) of the expander (3) and disposed between the pulley (5) and at least one operating element (9), a coupling device (8) including at least one elastic operating element (9) arranged within an operating element accommodation (10) in an axially deformable manner, and a pressure device (11) connected to the operating element accommodation (10) via a fluid line (12) and configured to apply pressure to the operating element accommodation (10). The at least one operating element (9) may be deformable in an axial direction (13)such that the at least one operating element (9) adjusts the drive disk (7) into force-transferring contact with the pulley (5) when the at least one operating element (9) is deformed by a pressure applied to the operating element accommodation (10) by the pressure device (11).

Description

technical field [0001] The invention relates to an engine assembly according to the preamble of claim 1 comprising an internal combustion engine and an expander which can be coupled to the internal combustion engine in a force-transmitting manner. The invention also relates to a method for starting an expander with an internal combustion engine comprising such an engine assembly. Background technique [0002] A general engine assembly is known from DE 10 2012 204 368 B4, comprising an internal combustion engine and an expander which can be coupled to the internal combustion engine in a force-transmitting manner. The internal combustion engine is thus used to drive the first shaft, wherein a fluid-operated coupling arrangement which can be operated under overpressure or underpressure is able to couple the steam engine to the second shaft for driving purposes. Thereby a freewheel cooperating with the coupling arrangement is arranged between the first shaft and the second shaf...
