Description

Technical Field

[0001] The present invention relates to a hybrid drive system for a motor vehicle, comprising an electric motor having a rotor and an input shaft of a downstream drive system device effectively connected to the rotor, wherein a connecting device connected to the rotor is rotatably coupled and axially floatingly connected to the input shaft. Background Technology

[0002] Hybrid drive systems of the same type have an internal combustion engine and an electric motor, which are connected to each other directly or via an intermediate disengagement clutch. Downstream of the electric motor rotor is a drive unit, such as a transmission with an input shaft. For example, as known from publications DE 10 2014 222 644 A1 and DE 10 2016 217 220 A1, a connecting device is provided to connect the rotor to the input shaft, which is rotatably connected to both the rotor and the input shaft and is axially floating on the input shaft. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to improve a hybrid drive system of the same type. In particular, the technical problem to be solved by the present invention lies in providing a hybrid drive system that is easy to install and capable of axial tolerance compensation.

[0004] The solution to the aforementioned technical problem provided by this invention is the technical solution of claim 1. The dependent claims of claim 1 describe advantageous embodiments of the technical solution of claim 1.

[0005] The proposed hybrid drive system is specifically for motor vehicles and includes an internal combustion engine and an electric motor that can be coupled directly to the internal combustion engine or via a disengagement clutch. The disengagement clutch, depending on the situation, can be positioned upstream or downstream of a torsional vibration damper (e.g., a dual-mass flywheel) between the crankshaft of the internal combustion engine and the rotor of the electric motor.

[0006] A drive system is located downstream of the rotor, such as a multi-stage transmission that can be engaged or automatically switched, like a dual-clutch transmission or a continuously variable transmission (CVT), connected between the rotor and the drive wheels. The drive system may include a friction clutch, a dual clutch, a torque converter, etc., effectively connected to the rotor. In this case, the rotor is effectively, for example, rigidly torsional (anti-torsional) or elastically torsionally connected to the input shaft of the drive system to transmit the applied torque. For this purpose, a connecting device is used, which is rotationally engaged and axially floating with the input shaft.

[0007] To improve the connection of an electric motor or a hybrid head unit consisting of an internal combustion engine and an electric motor to the input shaft, enabling compensation for misalignment between the rotation axis of the hybrid head unit and the input shaft, and facilitating installation between the hybrid head unit and the downstream drive system, the connecting device is accommodated on the input shaft by means of a spring effectively arranged between the connecting device and the input shaft, axially preloaded relative to a stop on the rotor. This indicates that the connecting device is torsionally accommodated, for example, on the internal teeth of the rotor and is axially preloaded relative to the rotor after the rotor or hybrid head unit is connected to the input shaft. This means that it is unnecessary or only necessary to pre-fix the connecting device axially to the rotor to prevent detachment, thereby saving axial structural space by eliminating the stop in both axial directions, thus saving both axial structural space and installation costs.

[0008] Axial preload between the connecting device and the input shaft is achieved using spring components (such as helical compression springs, disc springs, diaphragm springs, etc.). These spring components provide axial support to the connecting device on one hand, and directly or indirectly to the input shaft on the other. Multiple identical spring types or combinations of these spring types can be connected in series and / or parallel to form the spring components. For example, linear, decreasing, or increasing characteristic curves can be formed through axial preload of the spring components.

[0009] The spring element can be arranged directly between the input shaft and the connecting device, for example, in an axially preloaded manner. For this purpose, a surrounding axial stop, such as an annular edge, can be provided on the input shaft, and the spring element is supported on this surrounding axial stop. Alternatively, the spring element can be accommodated on a diameter that is smaller than the diameter of the input shaft, wherein the spring element is supported on a boss designed between the diameters. On the opposite side, the spring element is supported on the connecting device. Here, the connecting device can axially overlap the spring element in a sleeve-like manner.

[0010] Alternatively, the pressure member acting on the connecting device can be housed on the input shaft in an axially movable and pre-loaded manner. This pressure member can be housed on the input shaft in a preventable disengagement manner, for example, by means of a stop, in an axially restricted manner. In this case, the spring member is arranged between the stop on the input shaft and the pressure member. Here, the pressure member acts axially rigidly on the connecting device.

[0011] In an advantageous embodiment of the proposed hybrid drive system, the connecting device can be designed as a torsional vibration damper, having an input component rotatably connected to the rotor, an output component rotatably connected to the input shaft, and a spring device acting axially between the input component and the output component. The spring device may include, for example, helical compression springs or groups of helical compression springs arranged circumferentially on one or more diameters to form single-stage or multi-stage characteristic curves. The torsional vibration damper can be designed as a disc damper, wherein the input component and the output component each correspond to at least one disc-shaped component with a spring window that is rotatably rotatable about a rotational axis, in which the helical compression spring is housed. For example, two axially spaced and connected disc-shaped components may be provided on the input or output side, wherein at least one of the input-side disc-shaped components, or the design connecting it to the disc-shaped component, can be rotatably connected to the internal teeth of the rotor, and the other disc-shaped component can form an axial stop for the input component with the rotor (e.g., the end face of the rotor facing the transmission side). The output-side disc-shaped component may include an output hub integrally or separately, the output hub being housed on the external teeth of the input shaft in a rotationally engaged and axially movable manner by means of internal teeth.

[0012] The preload of the connecting device designed as a torsional vibration damper can be set relative to the input component of the torsional vibration damper. This indicates that the pressure member, preloaded directly or preferably by the spring member, acts axially on the input component and axially preloads the input component relative to the rotor. In the case where the input component consists of two axially spaced disc-shaped components, the disc-shaped component axially acted upon by the spring member can, for example, be preloaded relative to the rotor, while the other disc-shaped component forms a rotationally engaged connection with the rotor. In an alternative embodiment of a hybrid drive system with a connecting device designed as a torsional vibration damper, the output component can be axially preloaded relative to the input shaft.

[0013] The input and output components of the torsional vibration damper can be axially pre-tightened relative to each other in order to position, for example, two axially spaced disc-shaped components connected to each other and a disc-shaped component arranged between the two disc-shaped components.

[0014] In an alternative embodiment of a hybrid drive system with a connecting device designed as a torsional vibration damper, the connecting device is designed in a torsional (rigidly torsional) manner. In this case, the connecting member is designed, for example, as a disc-shaped component with an integral or separate output hub, wherein the disc-shaped component is radially externally connected to the rotor in a rotational fit and is axially preloaded relative to the rotor (e.g., relative to a retaining ring) by a spring member.

[0015] However, in order to incorporate a device on the anti-torsional connection for isolating torsional vibrations remaining after passing through an upstream torsional vibration damper if necessary, the centrifugal pendulum can be integrated into the anti-torsional connection. Here, the connection serves as a pendulum mass support, on which the oscillatingly suspended pendulum masses are suspended in a circumferentially distributed manner in the centrifugal force field of a rotor rotating about a rotation axis. The pendulum mass support can be designed as a pendulum flange having pendulum masses arranged on both sides, wherein axially opposing pendulum masses are connected to each other by means of connectors (e.g., spacer bolts, intermediate members, etc.) passing through recesses in the pendulum flange. The self-aligning bearing generating the oscillation capability can consist of raceways arranged on the pendulum masses and the recesses of the pendulum flange, on which pendulum rollers roll. Alternatively, the self-aligning bearing can consist of raceways radially stacked in a plane on the recesses of the pendulum flange and the intermediate members passing through the recesses, and pendulum rollers rolling on the raceways. For each pendulum mass unit consisting of two axially opposed pendulum masses, two self-aligning bearings can be provided, arranged circumferentially around the center of gravity of these pendulum mass units at a certain distance.

[0016] In an alternative embodiment of the connecting device with an integrated centrifugal pendulum, the connecting device may consist of two axially spaced and interconnected disc-shaped components, which serve as pendulum mass supports and house pendulum masses arranged in a circumferential manner. In this embodiment, the self-aligning bearings are respectively formed in axially opposite recesses of the disc-shaped components and in raceways machined on the pendulum masses, between the pendulum rollers that pass through the recesses and roll on the raceways.

[0017] A circumferentially acting friction device may be provided between the rotor and the input shaft to dampen circumferential clearances, for example, in rotary-fit connections (e.g., the engagement between the rotor and the connecting device and / or the input shaft and the connecting device). For example, a friction engagement may be designed at the frictional contact between the spring or pressure member and the connecting device (e.g., the input or output component of a torsional vibration damper, the pendulum mass support of a centrifugal pendulum, or a disc-shaped component designed in an anti-torsional manner). This friction engagement acts circumferentially within the circumferential clearance (e.g., backlash) during relative rotation, thereby preventing or at least reducing the impact of hard metals, such as clanging noise or load shocks, when the direction of the applied torque changes. This friction engagement may be designed as a metal-to-metal friction pair, and preferably, a friction ring may be inserted, for example, between the spring or pressure member and the connecting device to stabilize the friction engagement. Furthermore, this friction engagement may be torsionally arranged on one of the components that can rotate relatively relative to each other with limited capacity. Attached Figure Description

[0027] Figure 1 This is a partially shown cross-sectional view of the upper part of the hybrid drive system 1, arranged around the rotation axis d. The hybrid head unit 2 is arranged between an internal combustion engine (not shown) and a transmission (not shown) extending downstream to the drive wheels. Shaft 3 connects the hybrid head unit 2 to the internal combustion engine, and input shaft 4 connects this hybrid head unit to the transmission.

[0028] The hybrid head unit 2 includes a motor 5 having a stator 6 and a rotor 7. A disengagement clutch 8 and a connecting device 9, which is designed here as a torsional vibration damper 10, are arranged radially inside the rotor 7.

[0029] The housing 11 of the hybrid head unit 2 is securely connected to the housing of the internal combustion engine and houses the stator 6. The rotor 7 is rotatably and axially fixed on the housing 11 by means of a bearing structure 12. The disengagement clutch 8 is arranged between the shaft 3 and the rotor as a wet-operated and pressed multi-plate clutch, and is hydraulically operated by means of an operating device 13.

[0030] The connecting device 9 forms a connection between the rotor 7 and the input shaft 4. In the illustrated embodiment, the input shaft 4 is designed to be elastically torsionally operated by means of a torsional vibration damper 10 integrated into the connecting device 9.

[0031] The input component 14 consists of two disc-shaped components 15 and 16, axially spaced apart and connected to each other by means of a spacer bolt 17. The output component 18 consists of a disc-shaped component 19 axially arranged between the two disc-shaped components 15 and 16. This disc-shaped component has an output hub 20 integrally formed therein in the radial direction. This output hub is connected to the input shaft 4 by means of internal teeth 21 in a rotatable and axially movable manner. The disc-shaped components 15, 16, and 19 have spring windows 22 distributed on the circumference. In these spring windows, the helical compression springs 24 of the spring device 23, which acts circumferentially between the input component 14 and the output component 18, are arranged circumferentially and are subjected to circumferential force when the input component 14 and the output component 18 rotate relative to each other.

[0032] The disc-shaped component 15 is connected to the disc-shaped drive component 25, for example by riveting, which is radially externally housed in the internal teeth 26 of the rotor 7 in an axially movable and torsion-resistant manner.

[0033] To axially fix the torsional vibration damper 10 or connecting device 9 relative to the rotor 7, the input component 14 is axially preloaded relative to the input shaft 4, such that the radially extending disc-shaped component 16 of the input component 14 forms an axially preloaded stop, such as an axial stop 28, on the end face 27 of the rotor. This preload is achieved by means of a pressure member 29 arranged around the input shaft 4. The pressure member 29 contacts the disc-shaped component 16 and is axially preloaded relative to the input shaft 4 by means of a spring member 30. For this purpose, the spring member 30 is axially preloaded between the pressure member 29 and the stop 31 of the input shaft 4.

[0034] To axially position the output component 18 relative to the input component 14, the spring 32 is axially preloaded between the disc-shaped components 15 and 19, such that the disc-shaped component 19 abuts against the protrusion 33 of the disc-shaped component 16. When the hybrid head device 2 is not engaged, the locking ring 34 arranged on the input shaft 4 forms an anti-disengagement device for the pressure component 29 and the spring 30.

[0035] When relative rotation occurs between the input component 14 and the output component 18, friction occurs at friction point 35 between the pressure component 29 and the disc-shaped component 16. This friction can be configured as the frictional hysteresis of the torsional vibration damper 10. Furthermore, the backlash and frictional torque located between the drive component 25 and the rotor 7, and, depending on the situation, between the output hub 20 and the input shaft 4, can be superimposed to eliminate or at least reduce any clanging and impact noise that may occur during torque reversal.

[0036] The hybrid drive system 1 is preferably installed such that the hybrid head unit 2 is fixed to the housing of the internal combustion engine. In this case, the hybrid head unit 2 includes a connecting device 9 with a torsional vibration damper 10. This allows the transmission to be visibly engaged with the input shaft 4 and simplifies the installation of the transmission by engaging an invisible connection between the rotor 7 and the connecting device. By means of this engagement process, the connecting device 9 is axially fixed by forming a stop between the rotor 7 and the disc-shaped component 16, specifically, the disc-shaped component 16 is axially loaded by a preloaded pressure member 29 achieved by means of a spring member 32.

[0037] Reference Figure 1 , Figure 2 The relative connection device 9a is shown. Figure 1 The modified pre-tightened upper part, this connecting device can replace Figure 1 The connecting device 9 is used in the hybrid drive system 1. In this case, the pressure member 29, which is axially acted upon by the spring member 30, preloads the output hub 20a via the disc-shaped member 19a of the output member 18a of the torsional vibration damper 10a. The prestress is transferred by the spring member 32a to the disc-shaped member 16a of the input member 14a of the torsional vibration damper 10a, which forms a stop for the rotor 7. This spring member transfers the displacement of the disc-shaped member 19a to the disc-shaped member 15a and from there to the disc-shaped member 16a, which is firmly connected to the disc-shaped member 15a.

[0038] and Figure 1 and Figure 2 The pre-tightening of the connecting devices 9 and 9a is different. Figure 3 The direct preload of the connecting device 9b, modified by a pressure member, is shown in cross-sectional detail. For this purpose, a member 36b, such as a disc-shaped component of the input part of the output hub or the torsional vibration damper of the connecting device 9b, is arranged on a shoulder 37b with a smaller diameter around the rotation axis d of the input shaft 4b. A spring member 30b, such as a helical compression spring 38b, axially preloads the member 36b and supports it on a stop 39b of the input shaft 4b. The member 36b can overlap the spring member 30b in a sleeve-like manner.

[0039] Figure 4 Showing relative Figure 2The upper part of the connecting device 9c is modified from the connecting device 9a. The output component 18c of the torsional vibration damper 10c of the connecting device 9c is axially acted upon by the pressure member 29 in a manner similar to that of the connecting device 9a. Unlike the connecting device 9a, the axial prestress is transferred from the output hub 20c, which has the disc-shaped component 19c, to the disc-shaped component 15c of the input component 14c through direct contact with the disc-shaped component 19c. In this case, the disc-shaped component 16c, which is firmly connected to the disc-shaped component 15c, is obtained by means of... Figure 1 The rotor of the motor forms an axial stop. After the axial stop is formed between the disc-shaped component 16c and the rotor, the disc-shaped components 15c, 16c, and 19c are axially positioned relative to each other by means of the force-balanced spring components 32c and 30.

[0040] Figure 5 For relative Figure 2 A detailed cross-sectional view of the modified connecting device 9d compared to the connecting device 9a. Unlike the connecting device 9a, a friction ring 40d is centrally arranged on the output hub 20d between the pressure member 29 and the disc-shaped member 19d. The friction ring 40d is set with a predetermined friction torque to reduce gear noise. Since there is no relative rotation between the input and output components of the torsional vibration damper, no hysteresis covering this torsional vibration damper is provided.

[0041] Reference Figure 1 , Figure 6 The replacement of the connecting device 9e is shown in cross-sectional detail. Figure 1 The axial stop 28e is designed for the axial stop 28. For this purpose, on the internal teeth 26e of the rotor 7, the locking ring 41e is axially preloaded relative to the disc-shaped part 15e of the input part 14e of the torsional vibration damper 10e by a spring 30 that is radially internally disposed on the input shaft 4.

[0042] Reference Figure 1 , Figure 7 and Figure 8 The upper parts of the connecting devices 9f and 9g, which are used in the hybrid drive system 1 and are used as alternative connecting devices 9, are shown in cross-sectional view. The connecting devices 9f and 9g are designed to resist torsion between the rotor 7 and the input shaft 4 and are pre-tensioned axially relative to the rotor 7 by means of the pressure member 29 and the spring member 30 axially supported on the input shaft 4, in the case of forming axial stops 28 and 28e.

[0043] To adapt to the rotational speed and isolate torsional vibration, the connecting devices 9f and 9g have centrifugal pendulums 41f and 41g.

[0044] Figure 7The connecting device 9f includes two disc-shaped components 15f and 16f fixed to the output hub 20f at an axial distance. These two disc-shaped components together constitute the pendulum mass support 42f of the centrifugal pendulum 41f. For this purpose, the disc-shaped components 15f and 16f accommodate pendulum masses 43f arranged circumferentially therebetween and form two self-aligning bearings 44f circumferentially spaced for each pendulum mass. The self-aligning bearings 44f are composed of axially opposite recesses 45f and 46f with raceways 47f and 48f, on which the pendulum roller 49f rolls.

[0045] The disc-shaped component 15f is connected to the internal teeth 26 of the rotor 7 in a rotational fit, while the disc-shaped component 16f forms an axial stop 28 for the rotor 7.

[0046] Figure 8 The connecting device 9g includes an output hub 20g that meshes with the input shaft 4. This output hub has a disc-shaped component 15g, which is designed as a pendulum flange-shaped pendulum mass support 42g and has pendulum masses 43g arranged circumferentially on both sides. The axially opposite pendulum masses 43g are connected together by a connector 50g passing through the disc-shaped component 15g to form pendulum mass units. Self-aligning bearings (not shown) are provided between these pendulum mass units and the pendulum mass support 42g.

[0047] The disc-shaped component 15g is radially externally connected to the internal teeth 26 of the rotor in a rotational engagement manner and is axially pre-tightened relative to the locking ring 41e by means of the pressure member 29 in the case of forming an axial stop 28e.
