Definitions
- the invention relates to a dual-mass flywheel for internal combustion engines with a drive-side flywheel and an output-side flywheel, which are mounted concentrically to one another and connected to one another via a torque-transmitted torsion spring and can be rotated relative to one another to a limited extent, and to an electric starter generator, the rotor of which is connected to the flywheel.
- Flywheels of motor vehicles with manual transmissions and a high level of comfort are usually designed as dual mass flywheels, the drive-side flywheel rigidly connected to the crankshaft of the engine and the drive-side flywheel forming part of the motor vehicle clutch being connected to one another via at least one torsion spring.
- the torsion spring usually consists of a plurality of helical compression springs arranged in the circumferential direction; it serves to isolate vibrations in the drive train of the motor vehicle.
- Such a two-mass flywheel is known (DE 36 21 997 A1).
- the relatively high weight is perceived as disadvantageous, which is essentially determined by the two flywheels.
- the drive-side flywheel is designed to be as inert as possible and the torsion spring is made as soft as possible.
- electric starter generators Compared to electric starters, which are mechanically coupled to the flywheel only for the starting process of the internal combustion engine, electric starter generators have the essential advantage that the mechanical starting energy is transmitted without contact and thus without wear. In addition, the starting process does not cause any additional noise, so that an automatic start-stop system with frequently required starting processes can be implemented.
- the rotor is connected directly to the flywheel or to the drive-side flywheel of the dual-mass flywheel and is therefore in direct drive connection with the crankshaft.
- the mass of the flywheel is increased overall, which in turn leads to an increase in the total weight of the Internal combustion engine with its drive train and thus to an undesirable increase in the vehicle weight, but on the other hand also to an increase in the rotating mass of the internal combustion engine, which results in greater inertia against rapid speed changes.
- the object of the invention is therefore to design a two-mass flywheel for internal combustion engines of the type mentioned in such a way that the disadvantages mentioned, in particular an increase in the flywheel mass, are avoided by using the electric starter generator.
- This object is achieved in that the rotor of the starter generator is connected to the flywheel on the output side.
- the flywheel ring on the output side For effective torsional vibration damping in a two-mass flywheel, it is necessary for the flywheel ring on the output side to have a sufficiently large mass. If the rotor of the electric starter generator is connected according to the invention to the flywheel on the output side, its mass can be reduced to the same extent that its mass is increased by the attachment of the rotor.
- the total mass of the component consisting of the flywheel ring on the output side and the rotor of the starter generator can therefore be selected to be approximately as large as that of a flywheel ring on the output side without a rotor.
- the rotor of the starter generator does not have to contribute to increasing the mass of the internal combustion engine.
- torsional vibrations caused by the internal combustion engine do not lead to nonuniformity of the rotor rotation, because these torsional vibrations are largely eliminated during the torque transmission from the drive-side flywheel to the output-side flywheel.
- the flywheel mass requirement on the motor side is usually sufficiently covered by the primary inertia of the dual-mass flywheel, so that the arrangement of the inertia of the armature of the electric machine on the secondary side allows the drive train to settle to a much greater extent.
- the higher torsional inertia on the secondary side of the dual-mass flywheel enables the use of a stiffer torsion spring between the primary and secondary flywheel mass and thus a stiffer coupling between the engine and vehicle with improved longitudinal dynamics.
- the starting height can also be significantly reduced and the mass and the inertia on the primary side can be reduced.
- the substantially ring-shaped rotor of the starter generator is mounted laterally on the peripheral edge of the drive-side flywheel ring, preferably on the side of the drive-side flywheel ring on the drive-side flywheel ring. This results in a space-saving arrangement for the starter generator.
- the starter generator and the drive-side flywheel are arranged radially one inside the other.
- the rotor of the starter generator is arranged radially outside the circumference of the drive-side flywheel. This contributes in particular to a space-saving arrangement, taking into account that it is sufficient for reasons of torsional vibration damping, the drive-side flywheel with a relatively low mass and thus smaller diameter than the flywheel ring on the output side. The difference in diameter of the two flywheel rings resulting from this consideration is used here to provide space for the arrangement of the starter generator
- the torsion spring of the dual-mass flywheel can be designed to be bridgeable, for example by an electromechanical device. This creates the possibility of establishing a direct, largely torsionally rigid connection from the starter generator to the crankshaft for the starting process
- the drawing shows an axial section of a two-mass flywheel 1 in a driveline of a motor vehicle, only the parts above the axis of rotation 2 being shown in section
- An anti-flywheel ring 3 is connected to the crankshaft (not shown) of the motor vehicle engine and is flanged, for example, to the flange of the crankshaft by means of screws 4
- a torsion spring 7 is arranged between the drive-side flywheel 3 and the driven-side flywheel 5.
- a clutch disc 12 is connected to a transmission input shaft 14 of the motor vehicle by means of a splined hub 13.
- the clutch disc 12 is arranged between a clutch surface 14 of the drive-side flywheel 5 and a movable pressure plate 15, which is acted upon in the axial direction by a pressure spring 16 designed as a plate spring.
- the pressure spring 16 is movably mounted on pins 17 on a clutch cover 18 connected to the drive-side flywheel 5 and is actuated by a disengaging sleeve 19 via a thrust bearing 20 designed as a roller bearing.
- the internal combustion engine on the crankshaft of which the dual-mass flywheel 1 is attached, is equipped with an electric starter generator 21, which is designed, for example, as an electrical asynchronous machine and is used both for generating the required electrical energy and for starting the internal combustion engine.
- an electric starter generator 21 which is designed, for example, as an electrical asynchronous machine and is used both for generating the required electrical energy and for starting the internal combustion engine.
- the starter generator 21 has a starter 22 connected to the (not shown) housing of the internal combustion engine, which essentially consists of a stator winding 23 and a stator laminated core 24.
- the starter generator 21 has a rotor 25, the rotor winding 26 and the rotor laminated core 27 are attached to a support ring 28, which is attached laterally to the drive-side flywheel 5 by means of fastening screws 29.
- the essentially ring-shaped rotor 25 of the starter generator 21 is attached to the drive-side flywheel 5 on the side facing the drive-side flywheel 3 and surrounds the circumference of the drive-side flywheel ring 3.
- the drive-side flywheel 3 is designed with a much smaller diameter than the output-side flywheel 5.
- the resultant annular step laterally next to the peripheral edge of the drive-side flywheel 5 and outside the circumference of the drive-side flywheel 3 is essentially filled by the starter generator 21, so that there is only an insignificantly higher space requirement for this.
