Definitions
- the invention relates to a coupling device for a hybrid module comprising an electric machine and a connectable internal combustion engine, comprising a first, a second and a third partial clutch, the first partial clutch for switching on the internal combustion engine and the second and the third partial clutch for sharing one over the Internal combustion engine or the electric machine introduced torque to various gear stages of a downstream gear, as well as a gear wheel that can be driven via the electric machine, is arranged adjacent to a wall of a gearbox housing and is non-rotatably connected to a rotor, which is coupled to all partial clutches, and via a roller bearing is mounted on a housing bottom of the transmission housing.
- Such a coupling device also called a triple clutch, is used in a known manner for the temporary production of a torque-transmitting force circuit between a drive shaft of an internal combustion engine or an electric motor and an output shaft running to a transmission.
- So-called hybrid modules are increasingly being used in modern motor vehicles, which means that two drive units are provided, one in the form of an electric machine, the other in the form of an internal combustion engine. Both machines can be coupled selectively or cumulatively with a downstream transmission via the coupling device.
- the clutch device has a total of three partial clutches, a first partial clutch, usually called the K0 clutch, serves to couple the internal combustion engine to the downstream transmission, with the individual gear stages then selectively via the second or third partial clutch, usually K1 and Called K2 clutch.
- the electric machine is coupled to a gearwheel of the clutch device, which is also coupled to the second partial clutch and the third partial clutch via a rotor, so that the torque introduced via the electric machine can also be distributed to the downstream gear stages.
- the first partial coupling i.e. the K0- Coupling
- the K0- Coupling also to couple the electrical machine directly with the internal combustion engine in order to turn it on for starting.
- Each partial clutch comprises a corresponding disk pack with outer and inner disks as well as an outer disk carrier and an inner disk carrier, on which the corresponding outer and inner disks, which engage in one another per partial clutch, are axially displaceably guided.
- Each disk pack can be axially compressed separately in a known manner via a separate pressure element, usually a pressure pot, so that a force or frictional connection can be achieved by compressing the respective disk pack, which enables an introduced torque to be passed on from the respective drive machine.
- the electric machine is coupled to a gear of the clutch device.
- the electrical machine has a corresponding pinion on its output shaft that meshes with the gear.
- the gear itself is non-rotatably connected to a Ro tor, which in turn is non-rotatably connected to corresponding parts of the three coupling devices, usually one of their disk carriers, so that the torque delivered by the electrical machine is transmitted to the individual partial clutches via the gear and the rotor which rotate accordingly with the respective coupled disk carrier and the disks arranged thereon, while the other part of the respective partial clutch is at rest. Only when the respective partial clutch is actuated via the pressure element, i.e. the pressure pot, and the disk pack is axially compressed, the torque is passed on via the respective partial clutch.
- the pressure element i.e. the pressure pot
- the gear is mounted radially and axially via a correspondingly designed roller bearing on a housing bottom of the gearbox housing, for which the housing bottom übli chweise has a corresponding axial flange with a radially outer bearing seat on which the inner ring of the roller bearing is supported.
- the gearwheel extends, viewed radially, adjacent beard and as close as possible to a wall of the gearbox housing.
- the gear housing is made in two parts in this area, that is, the bearing wall in this area has a lower section that virtually forms part of the housing bottom, on which the roller bearing is fixed, and a section that extends radially further outward that continues the gearbox. Both housing parts are firmly connected to one another via screw connections. Although this leads to a stable, rigid housing design, it is, however, difficult to construct.
- the invention is based on the problem of specifying a comparatively improved coupling device.
- the housing wall and the housing boom are a one-piece gear housing part.
- the previously two-part housing structure be made in one piece in the area of the bearing of the gear or the gear stage, that is, a direct bearing support of the gear bearing on the gear housing bottom, which merges in one piece into the radially extending gear housing wall.
- This configuration is structurally much simpler, also from the manufacturing and assembly point of view, since only a one-piece housing component is Herge and has to be installed. So there are no two separate housing components that define this housing area, and which are to be provided with appropriate fasteners such as bores or internally threaded holes, etc. and are to be screwed together using appropriate fasteners, to produce and assemble.
- the one-piece design also results in an axial compacting option, since there are no axial overlap areas serving to fasten two components to one another.
- an axially extending ring flange with a radially outer bearing seat on which the roller bearing is mounted is on the gear housing part. is taken, provided.
- the inner ring of the roller bearing sits on this radial bearing seat, with the corresponding diameter being able to be selected so that a corresponding press fit results, which enables the bearing to be securely fixed.
- the housing wall is expediently provided at the same time as a stop for the inner ring of the roller bearing, that is, it is pushed axially until it runs against the housing wall, over which the roller bearing has reached its axial end position.
- a locking screw ring is expediently provided, which axially fixes the roller bearing or the inner ring on this side.
- wet clutches and this is what the clutch device according to the invention is, are usually carried out with a fully hydraulic clutch actuation.
- an actuating fluid i.e. an oil
- a fluid serving as such for cooling the clutch device usually again an oil
- Rotary feedthroughs are used to supply the respective fluid.
- circumferential grooves are expediently formed on the outer circumference of the rotor in a further development of the invention, of which channels lead into the area of the partial couplings, and which are sealed via respective sealing elements to the housing base extending across the rotor, with corresponding channel sections on the housing base are provided, at least one of which opens into a circumferential groove.
- a rotary feedthrough is al so formed via a rotor-side, radially outer circumferential groove, the order of the circumferential groove being encompassed by the housing base.
- Corresponding sealing elements ie suitable sealing rings, seal the circumferential groove from the housing base.
- the rotor can of course be rotated towards the fixed housing base, which means that the tiata also rotate, but nevertheless seal.
- At least one channel runs from the respective circumferential groove on the rotor side into the area of the partial clutches, where the respective fluid is either to be fed to the respective partial clutch for shifting or to cool the clutch device as a whole.
- at least one Kanalab section opening into a circumferential groove. Fluid supplied from outside the housing bottom can be guided into the circumferential groove via these channel sections and passed on from there.
- a plurality of circumferential grooves are now preferably provided in this area between the rotor and the housing base, that is to say that the rotary feedthroughs are as compact as possible in relation to one another and are also on the same radius.
- a particularly advantageous development of the invention provides that four circumferential grooves are formed axially one behind the other on the outer circumference of the rotor are, namely one each for supplying an actuating fluid to a partial clutch and one for supplying a cooling fluid to the partial clutches. This means that all four required circumferential grooves are formed in an axial row one behind the other on the outer circumference of the rotor and are sealed against the radially encompassing housing base by means of appropriate sealing elements.
- At least four separate channel sections are formed in the housing bottom, at least one of which opens into a circumferential groove so that the respective fluid can be selectively supplied to each circumferential groove.
- all four required rotary feedthroughs are therefore implemented in a very compact design in the area between the rotor and the housing base on the same radius or circumference in a very space-saving, axial arrangement, which leads to further compacting, as well as to a simplified construction, since the four circumferential grooves on the rotor outer circumference can beaded det in a simple manner, as well as the corresponding rotor-side channels and the corresponding channel sections in the housing base in the form of simple branch channels.
- the arrangement of the circumferential grooves should be such that it is avoided that a fluid introduced under pressure into a circumferential groove can flow into another circumferential groove due to leakage. Since the sealing elements or sealing rings allow a certain leakage due to the concept, such a transition can possibly be given, which can lead to losses in overall efficiency. To avoid this, either the distance between the circumferential grooves can be dimensioned accordingly. However, in order to keep this as small as possible, i.e. to maintain the axial compacting as much as possible, it is expedient if the circumferential groove, which is used to supply the cooling fluid, is between two circumferential grooves, which each serve to supply an actuating fluid to a partial clutch, is provided.
- the cooling fluid is supplied with significantly less pressure than the actuating fluid. This means that there is hardly any significant fluid transfer into one of the adjacent circumferential grooves that supply an actuating fluid.
- a small amount of leakage overflows into the circumferential groove supplying the cooling fluid is harmless, since this is only used for cooling, but not for building up a defined switching pressure.
- a collecting groove to be provided between two adjacent circumferential grooves which are used to supply an actuating fluid, which lungs via one or more discharge bores with one of the supply of cooling fluid in the area of the partial couplings serving channel is coupled.
- a leakage problem can also be eliminated via such a collecting groove connected between two circumferential grooves. If there is a slight leakage when an actuating fluid penetrates into a circumferential groove, the leakage fluid collects in the collecting groove, from where it is fed to the cooling fluid via the relief bores. Any leakage is therefore unproblematic here as well, with the collecting groove being able to be made correspondingly narrow, so that there is no noticeable axial extension of the groove arrangement.
- two circumferential grooves carrying an actuation fluid are preferably always separated via an intermediate groove, the intermediate groove being either a collecting groove or a further circumferential groove serving to guide the cooling fluid.
- the following circumferential groove sequence results: circumferential groove for actuating fluid collecting groove circumferential groove for actuating fluid circumferential groove for cooling fluid circumferential groove for actuating fluid.
- a specific embodiment of the invention provides that, viewed from the side of the partial couplings, first the circumferential groove assigned to the second partial clutch, then optionally the collecting groove, then the circumferential groove assigned to the first partial clutch, then the circumferential groove carrying cooling fluid and then the one assigned to the third partial clutch Circumferential groove is provided.
- the sequence can also be selected the other way round or differently.
- an expedient development of the invention provides that the second and third partial clutches are nested radially one inside the other and have a common disk carrier on which the inner disks of the second partial clutch radially on the outside and radially on the inside the outer disks of the third partial clutch are axially guided.
- a single disk carrier component is used to form the inner disk carrier of the second partial clutch and the outer disk carrier of the third partial clutch, which has corresponding outer and inner toothed sections in which the corresponding disks are rotatably but axially movable. This leads to further compaction, since, unlike in most cases, no two separate lamellar support components need to be installed.
- the figure shows a coupling device 1 according to the invention for a hybrid module comprising an electric machine that can be coupled and an internal combustion engine that can be coupled.
- the clutch device 1 comprises three separate partial clutches, namely a first partial clutch 2, usually called a K0 clutch, a second partial clutch 3, usually called a K1 clutch, and a third partial clutch 4, usually called a K2 clutch.
- Each of the partial clutches 2, 3, 4 has in itself
- the respective slats are axially movably guided and by means of a pressure element 20, 21, 22, which is each axially movable, against an abutment 23, 24, 25 axially movable to bring the respective lamella pack into frictional engagement.
- a pressure element 20, 21, 22 which is each axially movable, against an abutment 23, 24, 25 axially movable to bring the respective lamella pack into frictional engagement.
- the outer disc carrier 10 of the partial clutch 4 and the inner disc carrier 15 of the partial clutch 2 are formed on a common component.
- the first partial clutch 2 is used to switch on the internal combustion engine, which is not shown here, but is connected with its drive shaft to a stub axle 26, which stub axle 26 is coupled to the outer plate carrier 8 of the first clutch 2 part.
- the inner disk carrier 14 of the first partial clutch 2 is connected in a rotationally fixed manner to a rotor 27. If, accordingly, the disk set 5 and thus the first partial clutch 2 is closed via the pressure element 20, the torque introduced on the engine side is given to the rotor 27 via the partial clutch 2.
- the inner disk carrier 14 engages with the section running to the rotor 27, which has corresponding fingers, through corresponding recesses in the common disk carrier of the second and third partial clutches 3, 4, which defines the outer disk carrier 10 and the inner disk carrier 15, so that inevitably running a rotation of the inner disk carrier 14 of the first partial clutch 2 also leads to a rotation of this common disk carrier and thus a partial rotation of the second and third partial clutches 3, 4.
- the internal combustion engine torque transmitted via the rotor 27 can be transmitted via the respective partial clutch 3, 4 by corresponding actuation of the second partial clutch 3 or the third partial clutch 4 via the corresponding actuating element 21 or 22 and the frictional circuit of the respective disk pack 6, 7 are passed on.
- the torque is switched to the outer disk carrier 9, which is connected via a toothed hub 28 to a first drive shaft (not shown in more detail) running to the gearbox (not shown), which drive shaft is coupled to the first gear stage of the gearbox.
- the internal combustion engine torque introduced via the rotor 27 is passed to the inner disc carrier 16, which is connected via a toothed hub 29 to a two-th output shaft, not shown, which is connected to a second gearbox of the transmission, not shown is coupled.
- the torque introduced on the engine side can be switched to either the first or second transmission input shaft by respective switching of either the second partial clutch 3 or the third partial clutch 4.
- the partial clutch 2 must always be actuated, and one of the partial clutches 3 or 4.
- gearwheel 30 with which the electrical machine, not shown here, is coupled with a pinion arranged on its drive shaft, respectively.
- the gear 30 is mounted and supported on a gear housing component 32 via a roller bearing 31.
- the gear housing component 32 is made in one piece and has a first section 33 which forms the housing bottom 34 or egg NEN part of the housing bottom.
- the gear housing part 32 furthermore has a second partial section 35 which forms a radially extending housing wall 36, adjacent to which the gear wheel 30 extends radially.
- the gear housing part 32 has an axially extending annular flange 37 on which a radially outer bearing seat 38 is formed, on which the inner ring 39 of the roller bearing 31, which is divided here, rests.
- the inner ring 39 is axially supported on the housing wall 36, which has a corresponding stop 40 for this purpose, so that an axial securing is provided on this side.
- the axial locking takes place by means of a locking screw ring 41.
- the gear 30 itself is non-rotatably connected to the rotor 27, for example via a positive connection on the circumferential surface or end face of the gear, for example via a toothed section 42, so that a torque supplied by the electric machine and introduced via the gear 30 is applied to the rotor 27 . This therefore rotates when the electric machine is in operation. If this electric machine torque is now to be given to the transmission, either the second partial clutch 3 or the third partial clutch 4 is actuated so that the torque is passed on to the desired gear stage, as already described above for the internal combustion engine torque, which ben as described is also distributed via the rotor 27 and the partial couplings 3, 4. In contrast to the internal combustion engine, the partial clutch 2 does not have to be actuated in order to forward the electric machine torque.
- the internal combustion engine is to be turned on, for example in the event of an emergency, only the first partial clutch 2 can be closed without actuating the partial clutches 3, 4, so that a torque delivered by the electric machine via the gear 30, the rotor 27 and the first partial clutch 2 and the stub axle 26 is given to the coupled internal combustion engine for turning the same.
- the transmission housing part 32 is a one-piece housing part on which both a section 33 of the housing bottom 34 and a part section 35 of a transmission housing wall 36 is formed. It is therefore a simply designed, one-piece component that can be made sufficiently rigid.
- an actuating fluid supplied under pressure to the respective partial clutch is used, which is introduced into a corresponding annular chamber and builds up a corresponding switching pressure in this, which causes the respective pressure element 20 , 21 or 22, so the corresponding pressure pot, is axially displaced and presses against the respective Lamel lenvers 5, 6 or 7 to bring this into frictional engagement.
- This respective actuating fluid is supplied from outside, specifically via the gear housing part 32 or via the subsection 33 which forms the gear housing bottom 34.
- a cooling fluid is also supplied via this, which is generally conveyed into the area of the partial clutches 2, 3, 4 in order to carry out cooling in particular in the area of the respective lamellae and to dissipate the heat generated there.
- a total of four rotary feedthroughs 43, 44, 45, 46 are provided, each of which is in the form of circumferential grooves 47, 48, 49, 50 on the outer circumference of the rotor 27.
- the area of these circumferential grooves 47, 48, 49, 50 is encompassed by the transmission housing component 32, that is, its cylindrical inner lateral surface 51 extends radially adjacent to the circumferential grooves 47, 48, 49, 50.
- channel sections 54, 55, 56, 57 are provided on the gear housing part 32 and in the area of the housing bottom, which are shown here only in dashed lines, each one of the channel sections 54, 55, 56, 57 in one of the circumferential grooves 47, 48, 49, 50 opens.
- an actuation or cooling fluid can be directed into the respective assigned circumferential groove and either the respective partial clutch 2, 3, 4 can be switched in a targeted manner or the cooling fluid can generally be supplied.
- the arrangement is, for example, of the type that the circumferential groove 47 and the duct section 54 convey the actuating fluid for the second partial coupling 2, while the circumferential groove 48 and the duct section 55 convey the actuating fluid for the first partial coupling 2 hand off.
- the circumferential groove 49 and the associated channel section 56 convey the cooling fluid, while the circumferential groove 50 and the channel section 57 convey the actuating fluid for the third partial clutch 4.
- the individual circumferential grooves 47, 48, 49, 50 are connected to the corresponding rotor-side channels via corresponding radial bores, such a bore 58 being shown as an example, which connects the circumferential groove 49 to the channel 53.
- a relief groove 59 is provided between the circumferential grooves 47 and 48, from which one or more relief bores 60 here in the loading rich of channel 53 lead.
- Appropriate actuating fluid leaking from one of the adjacent circumferential grooves 47 or 48 is collected via this collecting groove and fed into the cooling fluid area, so that it is ensured that any leaked fluid does not get into an adjacent circumferential groove used for switching a partial clutch, which leads to a change the overall efficiency.
- Sufficiently good sealing of the individual circumferential grooves to one another is of course ensured via the corresponding sealing elements 52, nevertheless, due to the concept, there is a low leakage in this area, which, however, is not critical if such a collecting groove 59 is interposed.
