Definitions
- the invention relates to a torsion damper arrangement for a motor vehicle with a housing, wherein the housing includes a wet space.
- Torsionsdämpferanssenen for example, dual-mass flywheels, found in the drive train of a motor vehicle for damping torsional vibrations. These can be combined with centrifugal pendulums, it can also be used several torsion damper in a drive train.
- a swing start clutch arrangement is arranged in the housing of the torsion damper arrangement.
- the torsion damper assembly receives the flystart clutch assembly.
- the torsion damper assembly may be formed as a dual mass flywheel.
- a dual-mass flywheel differs from other torsion damper arrangements in particular in the ratio of the masses of primary and secondary side.
- the flywheel start clutch assembly may include a friction clutch and a dog clutch.
- the friction clutch may be designed so that it can lift only a part of these negative moments, and thus allows a smooth edge change of the dog teeth.
- the friction clutch can advantageously be designed so that it alone can transmit the entire negative torque in the pulling direction and the dog clutch can take over the remaining torque in the pulling direction.
- the friction clutch can lift it alone or be designed, for example, to 700 Nm, so that a safety reserve is available.
- the dog clutch is designed so that it can transfer 1,400 Nm. The positive torque in the pulling direction is therefore transmitted together when the 700 Nm is exceeded by both clutches, while the negative torques can be taken over by the friction clutch alone. As a result, in particular rattling noises on the dog clutch can be avoided.
- the friction clutch is designed with negative torque of 600 Nm to 400 Nm or 500 Nm, the dog clutch must take over the remaining negative moments, but then rattle noise of the dog clutch are excluded here, because the edge change of the claw, damped by the parallel friction clutch becomes.
- the flywheel clutch assembly may include an actuator having at least two actuating pistons.
- the swing start clutch Arrangement accordingly has a wet-running operation. Since the clutch or clutches of the flywheel clutch assembly are arranged in the wet space of the torsion damper assembly, the clutches are accordingly also wet running.
- actuating piston As a piston are basically understood all parts of the operation that follow the pressure chamber.
- An actuating piston can therefore be designed in several parts. Preferably, however, it is designed in one piece.
- the flywheel clutch assembly comprises at least one clutch, which may be basically wet or dry running.
- the use of two pistons results only when using at least two clutches.
- the embodiment or combination of a friction clutch and a dog clutch is a preferred embodiment, for example, a friction clutch and a freewheel or other variations are conceivable.
- a jaw member of a dog clutch may be formed on one of the pistons. Accordingly, one of the clutches is designed as a dog clutch. Due to the design of the claw element on the piston, two functions can be combined on one component, whereby a compact design can be realized.
- a friction surface of the friction clutch may be formed on one of the pistons.
- the other piston is formed as part of the coupling, which in turn a plurality of functions are formed on a single component.
- the number of components can already be reduced at these points. This can be done independently of the design of the other piston.
- the actuating device may have a single supply line. This is the case even if the flywheel clutch assembly has multiple clutches. These are namely not independent of each other to operate, but yes, the couplings are the positive torques in the pulling direction transferred together. Accordingly, the actuation takes place, with normally-opened clutches the engagement and with normally-closed clutches the disengagement, according to a predeterminable pattern. Accordingly, the pressurized areas of the actuating pistons may have a predetermined ratio that is selected in dependence on at least one biasing element. In normally-opened couplings, biasing elements may be present to bring the couplings into a defined home position. When engaging, this biasing force is overcome. This can be designed differently for the individual clutches.
- engagement conditions can be selected in which the respective other clutch is engaged.
- the friction clutch may be engaged first. If it then already transmits a defined torque in slip mode, the dog clutch is engaged. This moment can be precisely defined by the selection of the pressure surfaces. Thus, therefore, the dog clutch can be engaged depending on the engagement state of the friction clutch.
- the friction clutch is the one that remains closed longer. This is advantageous because it allows a jerk-free disengagement.
- a friction surface, in particular a friction cone, of the friction clutch can be formed on one of the pistons.
- This piston may preferably be used or arranged on the output side of the friction clutch.
- On the input side of the friction clutch may advantageously be arranged a friction element that is connected to one or the input hub.
- the friction element may be a lamella.
- the friction clutch preferably has a single lamella. Then the friction clutch is formed as a kind of single-disc friction clutch, the clutch disc is extremely simple.
- the friction surface on the piston is cone-shaped. Accordingly, the friction element, in particular the lamella, is then arranged obliquely.
- a part of the housing of the torsion damper assembly is a friction surface of the friction clutch.
- this part of the housing can be located on the output side of the friction clutch and at the same time belong to the primary side of the Torsionsdämpferaniser.
- the actuating device can have a single supply line. This makes it possible that the actuator is charged via the transmission input shaft with oil. As a result, expensive lines for the oil of the actuator can be avoided.
- the pistons can be mounted on an intermediate wall of the torsion damper arrangement.
- the oil supply can also be formed on this intermediate wall.
- the additional partition is connected to the Torsionsdämpferanssen.
- connecting to the hub or hubs on the input side would only increase the weight of the flywheel clutch assembly. But so the flywheel can be increased.
- the intermediate wall between the primary side and the secondary side may be arranged. At this point, the most space-saving installation is possible.
- the intermediate wall can be supported on an input hub.
- the support can be done via two radial shaft seals. Then, at this point, the supply of oil in the partition can be done.
- the intermediate wall may have at least one passage opening for oil. Then cooling oil of the couplings can be forwarded.
- the at least one passage opening is preferably arranged radially outside the clutch or couplings of the fly-starting clutch arrangement. Then the oil is guided by the prevailing centrifugal forces to the openings.
- the pistons can be arranged on the same side of the torsion damper arrangement, in particular on the same side of the intermediate wall.
- the engagement movement can take place towards the housing or towards the interior of the torsion damper arrangement. Preferably, a movement towards the housing. This results in an extremely space-saving design.
- the pistons may be arranged on different sides of the intermediate wall.
- the input hub in two parts, whereby the friction clutch and the dog clutch can be decoupled. This is possible with an arrangement of both pistons on the same side with less effort.
- the intermediate wall is preferably connected to the primary side of the torsion damper arrangement. More preferably, the fly-starting clutch arrangement is preferably arranged between the primary side and the secondary side of the torsion damper arrangement. In this case, the primary side of the torsion damper assembly form part of the housing of the torsion damper assembly.
- the intermediate wall can be supported on an input hub.
- the support can via two sealing elements, in particular radial shaft seals or rectangular sealing rings, done. Then, at this point, the supply of oil in the partition can be done.
- the actuating device can have a single pressure chamber.
- the engagement of the clutches can be designed via the design of the pressurized surfaces. Then a single pressure chamber is sufficient, so valves for controlling the pressure chambers can be omitted.
- the torsion damper assembly may have two input hubs.
- the couplings can thereby be decoupled.
- the entire torque can be transmitted via the fly-starting clutch arrangement.
- the torsion damper assembly is installed and transmits torque.
- the structure is such that the entire torque is transferable via the fly-start clutch arrangement.
- the actuating arrangement of the fly-starting clutch arrangement can form part of the flywheel mass of the torsion damper arrangement.
- the storable rotational energy can be increased. This results, for example, when the intermediate wall of the primary side of the torsion damper assembly is connected and the actuating arrangement is formed in the intermediate wall.
- the primary side of the torsion damper assembly may be supported on an input hub of the flywheel clutch assembly.
- the primary side forms part of the housing of the torsion damper assembly, which again space is saved in the axial direction.
- the dog clutch may be formed as a radial claw clutch. This means that the teeth of the dog clutch point in the radial direction.
- at least one clutch of the flywheel clutch assembly may be formed as a normally-opened clutch.
- both clutches of the flywheel clutch assembly may be formed as normally-opened clutches. This is advantageous when the motor vehicle is approached via the electric motor and accordingly emits no moment at the start of the motor vehicle, the engine. Then there is no actuating pressure available to open the clutches. Thus, an additional pumping device can be avoided.
- the invention relates to a motor vehicle with a Torsionsdämpferan Aunt.
- the motor vehicle is characterized in that the torsion damper arrangement is designed as described.
- FIG. 2 shows a torsion damper arrangement in a first embodiment
- FIG. 3 shows a torsion damper arrangement in a second embodiment.
- FIG. 1 shows a drive train 1 with an internal combustion engine 2, a
- Flywheel clutch assembly 3 a flywheel device 4, a clutch 5, an electric motor 6 and a transmission 7.
- the electric motor 6 can be configured as a single electric motor or as series-connected electric motors, it is essential here that the electric motor 6 in front of the transmission 7 on the drive train attacks.
- the flywheel clutch assembly 3 is characterized by its position in front of the flywheel device 4. This is due to the particular function of the flywheel clutch assembly 3, which is merely the high travel of the combustion Serving motor 2 is used and otherwise transmits the torque of the engine 2.
- the flywheel clutch assembly 3 separates the engine 2 from the remainder of the drive train in purely electronic operation, the electric motor 6 thus drives the flywheel device 4 as an energy store in purely electric motor operation.
- the additional power which the electric motor 6 has to apply for this purpose in purely electromotive operation, however, is less than the power reserve that would be required if the electric motor 6 had to accelerate not only this but also the flywheel device 4 for starting the internal combustion engine.
- the fly-starting clutch assembly 3 is not a starting clutch since it is not used to move the motor vehicle. Regardless of whether or not the motor vehicle is already in motion, the fly-starting clutch assembly 3 merely serves to start the engine 2. It is therefore interpreted by the interpretation forth, for example, in relation to the removal of heat differently interpretable as a starting clutch. In this respect, the different function, for example, in the amount of material of the pressure plate noticeable.
- FIG. 2 shows a torsion damper arrangement 8 as a flywheel device 4.
- the flywheel start coupling arrangement 3 is arranged inside the torsion damper arrangement 8 and therefore also inside the flywheel device 4.
- the swing start clutch arrangement 3 comprises a friction clutch 9 and a dog clutch 10. Parts of the flywheel clutch assembly 3 a part of the flywheel assembly 4. This consists of the torsion damper assembly 8 and parts of the flywheel clutch assembly. 3
- two input hubs 12 and 14 By the input hubs 12 and 14, the torque can be divided and thus the dog clutch 10 are protected against torque changes.
- the input hubs 12 and 14 can be screwed to the crankshaft 16 as shown in FIG. 2, but they can also be positively connected to the crankshaft via a serration.
- the input hubs 12 and 14 may be connected to the crankshaft via a plate assembly. In this case, the crankshaft can be screwed to a first plate and this with a second, which in turn is connected to the two input hubs. This results in an axially elastic connection between the crankshaft and the input hubs 12 and 14.
- the input hub 12 With the input hub 12 is connected as a friction member 18, a blade. This is attached to a hub shield of the input hub 12.
- the input side of the friction clutch 9 accordingly includes the input hub 12 with hub shield and the blade 18th
- the housing part 22 is at the same time the primary part of the torsion damper arrangement 8.
- the friction surface 24 can be arranged on the housing part 22 in the oblique part, in particular on a crank 26.
- the actuating piston 20 comprises a friction cone 28, which is also arranged on the output side.
- the friction clutch 9 is accordingly designed as a single-disc friction clutch, wherein the clutch disc as a disc le is formed and the output side friction partners are formed on the one hand on the actuating piston 20 and the other on the housing part 22. Accordingly, the output side of the friction clutch 9 is realized exclusively by already existing on the torsional damper or on the actuator components.
- the input hub 14 forms the input of the dog clutch 10, wherein the actuating piston 30 is also the jaw member of the dog clutch 10.
- the jaw clutch 10 is designed as a radial claw clutch, which is why the teeth 32 and 34 are formed in the radial direction.
- the counter teeth 36 and 38 are on the one hand on the input hub 14 and on the output hub on the intermediate wall 40.
- the intermediate wall 40 supports the actuating piston 20 and 30, while it is connected to the housing part 22.
- a portion of the supply line 42 passes through the intermediate wall 40, wherein both pistons 20 and 30 are actuated by the single supply line 42.
- the pressurized surfaces 44 and 46 are selected as a function of the biasing elements 48 and 50, so that the engagement of the dog clutch 10 can be done for example in a defined engagement state of the friction clutch 9.
- the actuating surface 44 of the friction clutch 9 is larger and, for example, the force of the biasing member 48 is smaller, so that the friction clutch 9 is first engaged. Only when a defined engagement state of the friction clutch 9, the force of the biasing member 50 is then overcome, so that the dog clutch 10 is engaged.
- the biasing elements 48 and 50 are preferably designed as tension springs, so that the friction clutch 9 and the dog clutch 10 are formed as normally-opened couplings.
- the intermediate wall 40 and the actuating piston 20 and 30 form part of the flywheel device 4. So they belong to the rotational energy storing mass, which is held rotating by the electric motor 6, while the engine is decoupled. Only the input hubs 12 and 14 and the friction element 18 are connected to the crankshaft 16 and thus to the engine 2. Only these parts are therefore not part of the flywheel device 4.
- the torsion damper arrangement 8 On the secondary side, the torsion damper arrangement 8 has a secondary element 52 which also forms the output of the torsion damper arrangement 8. This is enclosed by the housing part 54, which is connected to the housing part 22.
- the housing part 22 is supported by means of a bearing 56 on the input hub 12. Further thrust bearings 58 separate the intermediate wall 40 from the input hubs 12 and 14.
- the housing parts 22 and 54 enclose a wet space, wherein the torsion damper assembly 8 and the friction clutch 9 and the dog clutch 1 0 are designed to run wet.
- a centrifugal pendulum is arranged at the output of the torsion damper assembly 8.
- a second torsion damper arrangement also follows before the separating clutch 5. These are therefore arranged in the diagram according to FIG. 1 between the flywheel mass device 4 and the separating clutch 5.
- FIG. 3 shows a further embodiment of the torsion damper arrangement 8.
- the actuating pistons 20 and 30 are arranged on the same side of the intermediate wall 40, which is why only a single input hub 16 is present. But the intermediate wall 40 is still connected to the housing part 22 and thus to the primary side and a part of the friction clutch 9 is formed by the housing part 22 and by the actuating piston 20 as already described for Figure 2.
