Definitions
- the invention relates to a device for driving at least one Auxiliary unit of an internal combustion engine, the drive torque of the Internal combustion engine via the crankshaft to a first, connected to the crankshaft Pulley and from this by means of belt drive to at least one other than Drive of an auxiliary unit effective pulley is transmitted.
- To start internal combustion engines are usually powered by a battery powered starter used during the starting process with the internal combustion engine be brought into operative connection.
- a battery powered starter used during the starting process with the internal combustion engine be brought into operative connection.
- certain starting speeds must be guaranteed.
- the type and size of the Internal combustion engine is determined, especially during the starting process Belt drive and the auxiliary units driven by it.
- a Vibration state occur in which the natural frequency of the system is hit.
- the internal combustion engine is not in such unfavorable operating situations Able to achieve the necessary idle speed.
- the starting process takes time longer. This is due to the limited capacity of the battery Operating state problematic at least when cold starting.
- Out DE 43 09 548 A 1 is a drive for at least one auxiliary unit Internal combustion engine known. This is done by one, firmly on the crankshaft arranged driven wheel via a belt drive a drive wheel of the auxiliary unit (e.g. generator) driven.
- a freewheel is such arranged that on the one hand accelerated rotary movements of the crankshaft by the Transfer the engaged freewheel directly to the drive wheel of the auxiliary unit be, while on the other hand the freewheel is disengaged when the self-deceleration of the auxiliary unit is below the deceleration occurring on the crankshaft.
- EP 0 652 626 A1 describes a further solution for temporarily interrupting the Connection between the internal combustion engine and an auxiliary unit described.
- the auxiliary unit is a generator, on the drive wheel of which a belt runs the crankshaft is driven. Between the drive wheel of the generator and his Rotor-stator assembly, an electromagnetic clutch is arranged. With this Coupling can be the connection between the drive wheel of the generator and its actual electrical assembly are interrupted. It is possible to do this Establish connection only as soon as the battery charge is below one set value decreases. It is also possible to use this connection predominantly to maintain and to interrupt only when the engine is particularly stressed. Thus, the load on the internal combustion engine in selected operating states can be reduced.
- the drive wheel of the generator is also disengaged Rotor-stator assembly constantly driven by the crankshaft.
- the Vibration behavior in the start phase can therefore only be improved to a limited extent, because even with the generator disconnected, at least the belt drive is in motion.
- Another disadvantage is that the assembly to interrupt the Connection between crankshaft and generator directly in the auxiliary unit is integrated. If several auxiliary units are to be designed so that they can be switched off, a corresponding assembly is consequently required for each of the auxiliary units, so that the solution according to EP 0 652 626 A 1 also has a large component and Requires cost.
- the object of the invention is to provide a device with which the vibrations of belt drive and auxiliary units during the start-up process Internal combustion engine can be significantly reduced. This is to be achieved by the torque path from the crankshaft to several with just one assembly Auxiliary units can be interrupted.
- the internal combustion engine shown consists of an engine block 1 Drive torque is arranged in the interior of the engine block 1 and in the drawing not shown piston-connecting rod assemblies on the crankshaft 2 transferred. On the crankshaft 2 is outside of the engine block 1 Pulley 3 arranged. This first pulley 3 does not drive one either belt drive shown in more detail.
- This belt drive is again called Drive source effective for at least one auxiliary unit of the internal combustion engine.
- the belt drive is in each case with another, on the respective auxiliary unit arranged pulley in operative connection.
- a clutch 4 arranged in the drive train is between the crankshaft 2 and the first one connected to it Pulley 3 a clutch 4 arranged.
- this clutch 4 is provided directly in the contour of the crankshaft 2.
- the clutch 4 can also be integrated in the first pulley 3.
- the Coupling can be designed in various ways, for example as Magnetic clutch or as a centrifugal clutch. Regardless of the specific This coupling 4 is designed for the functionality of the device essential that the clutch 4 can be actuated depending on the crankshaft speed. For this actuation and the necessary detection of the speed preferably used the existing engine control unit.
- the clutch 4 When the internal combustion engine starts, the clutch 4 is first disengaged. In this operating state is the torque path from the crankshaft 2 to Pulley 3 interrupted. The belt running on this pulley 3, the therefore acts as a drive for the subordinate auxiliary units no drive, so that the auxiliary units from the drive torque of the crankshaft 2 are uncoupled. Thus, vibrations on the belt drive and the Ancillaries largely avoided.
- a successful start of the Internal combustion engine which by exceeding a predetermined speed (e.g. the Idle speed) can be seen, the clutch 4 is engaged and the Auxiliary drive now runs in a manner known per se.
