Definitions
- the invention is directed to a generator drive system for driving the generator of an internal combustion engine and possibly other ancillary components of that internal combustion engine. Furthermore, the invention is also directed to a method for tuning the operation of the generator of an internal combustion engine.
- Generator drive systems of the aforementioned type typically comprise a traction mechanism drive.
- traction means are now predominantly Flach, Dahlke ribbed belt, for example, so-called poly-V belt used. These belts are preloaded via tension pulley assemblies.
- when starting an internal combustion engine can occur during the first crankshaft rotations within the traction drive loads that are far above the loads occurring in the rest of normal operation.
- the engine starts significantly affect the life of the components of the traction drive and the driven units.
- the invention has for its object to provide solutions by which it is possible within a provided for the drive of a generator drive system ("FEAD") occurring loads, especially in the context of engine start operations to reduce.
- FEAD generator drive system
- a generator drive system for the generator of an internal combustion engine comprising a traction mechanism of a traction means which is guided over a generator rotor disk which serves to drive the generator, this drive system is characterized in that the generator so is formed and electrically connected, that the generator is temporarily operable as a motor, and that the generator is coupled to the generator pulley or the crankshaft pulley of the internal combustion engine via a one-way clutch which allows the generator in the context of its operation as an engine, the GE nerator running disk or taking into account a gear ratio, the crankshaft overhauled.
- the freewheel is designed as a sprag freewheel. This freewheel allows overtaking of the temporarily operated as an engine without further external influence benen generator. Furthermore, it is also possible to run the freewheel as Klemmfeder- freewheel, or possibly as an actively switchable freewheel.
- the switching of the generator into a coasting mode takes place according to the invention as a function of the operating state of the internal combustion engine or of the corresponding motor vehicle.
- the switchover of the generator into an engine operating mode takes place in the context of an engine start phase, so that the engine starter does not have to accelerate the rotationally mounted and inertia-bearing components of the generator.
- the concept according to the invention makes it possible to reduce the belt pretension set in the traction mechanism drive and thereby reduce the stresses on the components in the traction mechanism drive. As a result, high running times are achieved reliably even with low-cost components. In particular, costly and expensive components (for example heavy-duty clamps, special belts and the like) can be dispensed with in the FEAD.
- the generator is preferably designed so that it can accelerate its rotor structure and the components revolving therewith with sufficient dynamics (preferably at least slightly faster than the fastest accelerations of the engine under normal operating conditions).
- ECU Motor Viennaelektonik
- the belt drive with clamping systems and possibly existing decoupling elements runs through resonance areas that can lead to high load peaks. These resonance ranges can be overrun by the crankshaft without performance pick-up by the inventive concept without there being a pronounced coupling with the crankshaft system. This will shorten the start time. In particular, when a start-stop automatic used, the inventive concept proves to be particularly valuable. 4. In critical operating conditions (eg high non-uniformity due to engine full load at extremely low speed), the speed of the generator can be actively increased at least slightly above the rotor speed. 5.
- the alternator will be designed so that it provides a drive torque in overrun that is so high that it can also accelerate the other units of the FEAD, and thus the one sitting on the crankshaft
- the running disc always rotates slightly above the crankshaft speed in the above mentioned critical operating conditions. This makes it possible to accelerate the FEAD much more evenly.
- the superimposed accelerations caused by the combustion processes are eliminated, especially when the angular velocity set by the overrun of the generator is above the non-uniformity increased peak angular velocities. (eg KW speed 1500 +/- 400 revolutions per minute (rpm) then speed belt drive 1900 + x (about 2000 rpm))
- the generator speed (or that of the e-machine) can be lowered to the crankshaft rotational speed and the generator is driven by the traction drive and then operates again in the generator mode, ie. under delivery of electrical power).
- the inventively proposed temporary overrun operation of the generator can be prevented if the state of charge of the battery system makes this appear as indicated.
- the freewheels can be designed as purely mechanical components that allow overtaking as such. These freewheels can be designed in particular as sprag clutches with ramps on the inner ring or on the outer ring, as well as wrap spring clutches.
- the electric machine operable in both the generator operating mode and in the engine or coasting operating mode can also be used as an engine brake via the belt drive for regenerative braking according to another aspect of the present invention.
- This electrical power can be buffered in fast energy stores (batteries, capacitor systems eg gold or supercaps ..). The energy thus obtained can then be used for the above-mentioned special operating states.
- the belt drive / generator decouples at higher accelerations of the vehicle as described above is more mechanical line for driving the vehicle available. This gives us a higher elasticity in the acceleration, or there is a reserve available. Gff, can be realized by the inventively achieved peak power gain corresponding rear dimensions of the engine.
- FIG. 1 shows a schematic diagram to illustrate the inventive concept in conjunction with a for driving a
- Motor vehicle provided drive system.
- a drive system for a PkW is greatly simplified.
- This drive system comprises an internal combustion engine 1, a transmission 2 connected thereto for the purpose of effecting the drive for a power transmission.
- car required butterabgriffs, and a generator drive system (FEAD) for driving a generator 3 and possibly other ancillaries (not shown here).
- the generator drive system comprises a traction mechanism drive with a traction means 5 which is guided via a generator rotor disk 6 which serves to drive the generator 3 or, respectively, the kinematic integration thereof into the traction mechanism drive.
- the traction mechanism further comprises a crankshaft pulley 7 which sits on an end portion of the crankshaft 8 of the internal combustion engine 1.
- the generator drive system shown here is characterized in that the generator 3 is designed and electrically connected such that the generator 3 is temporarily operable as an electric motor, wherein the generator 3 is coupled to the generator pulley 6 via an overrunning clutch 4 which allows the generator 3 in the Berthebsmodus as a motor, the generator rotor disk 6 overtakes in terms of speed, ie turns faster than the generator pulley 6.
- this is connected via a power electronics 10 to an energy storage device 11.
- the control of the power electronics 10 via the engine control 12.
- This engine control 12 are the control-related sensor signals for the operating condition of the internal combustion engine and the vehicle equipped therewith available.
- control of the power electronics 10 takes place via the motor control in such a way that the rotor of the generator 3 reaches angular speeds which are above the current angular speeds of the generator belt pulley 6.
- the mass inertia of the rotor and the generator axle supporting it do not contribute any load in the traction mechanism drive.
- the generator 3 is finally decoupled from the traction mechanism drive in this mode of operation.
- auxiliary energy storage 13 for the temporary operation of the generator 3 with electrically accelerated rotor shaft.
- This auxiliary energy storage 13 may be designed so that its charge is designed only for a few generator acceleration processes. As far as this auxiliary energy storage 13 has a sufficient state of charge this is primarily used for the provision of the acceleration energy.
- charging module 14 can be further determined from which of the storage systems 11, 13, the temporarily required energy to be deducted. Furthermore, it can also be determined in conjunction with the loading module 14 where the delivered power is to be delivered as an actual generator in the course of a later operation of the generator.
- the auxiliary energy storage 13 can in this case be constructed so that it allows extremely high charging currents.
- the auxiliary memory 13 may be formed, for example, as a gold or supercap capacitor system.
- the auxiliary memory 13 is thus particularly suitable for receiving electrical power in a so-called regenerative operating mode, ie an operating mode in which the generator 3 taps power from the crankshaft 8 "pushed" via the transmission 2.
- the system according to the invention can be prepared as a self-matched module that includes the special generator's own control electronics and possibly also the auxiliary energy storage device 13.
- the signals required for the temporary operation of the generator 3 as itself akzelleherendes system can be provided as a simple 1/0 signals via the magnetic switch 15 of the starter 16 or the engine electronics 12 available.
- a pulser system can be provided by which speed information can be provided directly in the region of the generator by which an overtaking of the rotor of the generator can be adjusted.
- the freewheel 4 is arranged between the generator pulley 6 and the generator shaft.
- the invention expressly also includes such embodiments in which the freewheel 4 is arranged between the crankshaft 8 and the crankshaft pulley 7.
- the entire traction mechanism including the seated on the crankshaft 8 crankshaft pulley can be pre-accelerated.
- This special concept makes it possible to use the generator 3 for a short time to drive auxiliary equipment such as a power steering pump so that a steering assistance function is provided even when the internal combustion engine is switched off. By sitting on the crankshaft freewheel driving a same is avoided.
- the power electronics 10 is preferably designed so that it handles both the generator operation, as well as the temporary engine operation.
