Definitions
- the invention relates to an auxiliary unit module for an internal combustion engine, with an assembly support that can be attached to the internal combustion engine and at least one auxiliary assembly attached to the assembly support, according to the preamble of claim 1.
- auxiliary units serve for the proper functioning of the internal combustion engine and operate additional functions.
- auxiliary units are, for example, a generator, an air conditioning compressor, a water pump, an oil pump or the like.
- These auxiliary units are driven by the internal combustion engine by means of a drive belt, which runs from a pulley of a crankshaft of the internal combustion engine via corresponding pulleys on the auxiliary units.
- a particular problem is that the belt has to run in one plane if possible for a loss-free and low-wear run.
- the pulleys of the various auxiliary units must be aligned exactly parallel to one another and to the pulley of the crankshaft, and this alignment should not change as far as possible even under load.
- the present invention is therefore based on the object of providing an improved auxiliary module of the type mentioned above, the disadvantages mentioned above being overcome and an optimal and permanent adjustment of the pulleys to one another and thus an improved belt service life being ensured without additional adjustments when mounting an internal combustion engine .
- a housing of the at least one auxiliary unit is at least partially formed in one piece with the assembly carrier.
- the at least one auxiliary unit is advantageously connected to a crankshaft of the internal combustion engine by means of a drive belt, in particular a poly-V belt.
- each ancillary unit in a particularly preferred manner has a pulley, the drive belt via the The pulley of the crankshaft and the pulleys of the auxiliary units run essentially in one plane.
- a housing of the at least one auxiliary unit is formed completely in one piece with the unit carrier. This significantly increases the accuracy of adjustment between the auxiliary units themselves, since housing separating joints are already predefined and designed in one piece with the subframe.
- fluid channels for the inflow and / or outflow of a cooling and / or working medium for at least one auxiliary unit are preferably formed integrally in the unit carrier.
- the assembly carrier is also designed as an aluminum die-cast assembly carrier.
- a further reduction in connection points subject to tolerances is achieved in that components of the at least one auxiliary unit are formed in one piece with the unit carrier.
- the assembly carrier can be fastened to the front side or to the side of the internal combustion engine.
- the at least one auxiliary unit is an air conditioning compressor, a liquid-cooled generator, a water pump, a power steering pump and / or an oil pump.
- a piston raceway of the same is formed in one piece with the unit carrier in a Kiima compressor as an auxiliary unit.
- a belt tensioning device is also arranged on the assembly carrier in a particularly preferred manner.
- FIG. 1 shows a preferred embodiment of an assembly carrier of an auxiliary unit module according to the invention in supervision
- FIG. 11 is a schematic representation of a drive belt running over pulleys
- FIG. 13 shows an exploded view of components of a power steering pump to be installed in an assembly carrier
- FIG. 15 arrangement of a hydraulically damped belt tensioning device in a schematic representation 16 shows a sectional view along the line BB from FIG. 15.
- FIGS. 1 to 10 The preferred embodiment of an assembly carrier 11 according to the invention shown in FIGS. 1 to 10 comprises a frame 10, installation shafts 12, 14, 16 for auxiliary units and fastening eyes 18, 20 and 22. Furthermore, there are additional fastening points 24, 26 and 28 on arms 30, 32 and 34 are provided, which ensure increased rigidity of the assembly carrier 11 with respect to an internal combustion engine (not shown) or with respect to a crankcase of the internal combustion engine, to which the auxiliary unit module is attached. As can be seen in particular from FIGS. 2, 3 and 8 to 9, the frame 10 is designed such that it integrally forms housings 36, 38 and 40 for the auxiliary units to be installed in the installation shafts 12, 14 and 16.
- the individual further components are installed directly in the assembly carrier 11, so that there are no more joints between the housings 36, 38, 40 and the assembly carrier 11.
- the housings 36, 38 and 40 formed directly in the assembly carrier 11 ensure a defined position of the components and thus of the ancillary units relative to one another and also via the fastening eyes 18, 20, 22 and points 24, 26, 28 for a defined position of the ancillary units a crankshaft of the associated internal combustion engine.
- FIG. 11 shows the course of a drive belt 42 via a belt pulley 44 of a crankshaft (not shown), a belt pulley 46 of a power steering pump 48, a belt pulley 50 of an air conditioning compressor 52, a belt pulley 54 of a liquid-cooled generator 56 and a roller 58 of a belt tensioning device 60.
- the belt tensioning device 60 is preferably a hydraulically damped belt tensioning element which is arranged on the fastening eye 18. Due to the defined position of the components of the auxiliary units 48, 52 and 56, the pulleys 46, 50, 54 also have a precisely defined position relative to one another and to the pulley 44 of the crankshaft in such a way that the drive belt 42 runs exactly in one plane. This ensures the lowest possible wear and thus a long service life of the belt 42.
- FIG. 12 shows, by way of example, components of an air conditioning compressor 52 which are to be installed in an assembly carrier 11 according to the invention.
- this would be the installation shaft 14 forming the housing 38.
- These components include the pulley 50 of the air conditioning compressor 52, a shaft seal 62, a radial bearing 64, an axial bearing 66, housing screws 68 for the frame 10, a drive shaft 70, and a swash plate Piston 72, a radial bearing 74, a seal 76 to the assembly carrier 11, a piston raceway 78, a seal 80, a valve plate 82 with inlet / outlet valves, a further seal 84 and a rear cover 85.
- FIG. 13 An analog representation is shown in FIG. 13 for a power steering pump 48.
- the corresponding components which in the embodiment according to FIGS. 1 to 10 are to be installed in the installation shaft 16 forming the housing 40, include the pulley 46, a pulley adapter 86, a fixed bearing 88, housing screws 90, a rotor shaft 92, a radial shaft seal 94, a front pump cover 96 with pressure control valve and inlet and outlet connections, a housing sealing element 98, a sealing element 100, an O-ring 102, pressure-side control edges 104, a race ring 106, a vane wheel 108 with vanes, clamping and fixing pins 110 and a sealing and control edge disk 112 with pressure chamber channels.
