- the invention relates to a hybrid module for a hybrid drive of a vehicle, in which a conventional drive is combined with an electric machine.
- Hybrid drives are known in the prior art. Hybrid drives with an electrical machine arranged coaxially to the drive shaft are widespread. The prior art is also known in which the arrangement is axially parallel. Examples of this are DE 102017 110606 A1 or DE 102010003442 A1.
- the object of the invention is to provide a hybrid module that has a small axial installation space, for example, to be easily applicable to existing vehicle concepts, and has a needs-based lubrication concept. Further tasks are to improve security and usability.
- a hybrid module for arrangement between an internal combustion engine, an electric machine and a transmission, the hybrid module having an input shaft which is connected to a torsional damper attached to the internal combustion engine, an output shaft running coaxially with the input shaft being provided , which is connected to the transmission, wherein the output shaft is connected to the output side of an Anfahrele element, wherein the electrical machine is arranged axially parallel to the input shaft and output shaft, and wherein the electrical machine is connected to egg nem traction drive with the starting element, thereby characterized in that the hybrid module is divided into at least three separate oil spaces, that at least one of the oil spaces is designed as a dry space, that the torsion damper is provided in the dry space, that a bearing plate is provided which is arranged directly adjacent to the torsion damper is that at least two of the oil spaces are designed as wet spaces and separate from one another, and that a housing of the starting element forms one of the wet spaces.
- the hybrid module is arranged in the drive train between an internal combustion engine and a transmission and also has a connection to an electrical machine.
- the electrical machine is axially parallel to the ko axially arranged input shaft and output shaft or gear shaft. The axially parallel arrangement saves installation space in the axial direction.
- a torsional damper is connected to the internal combustion engine and is also non-rotatably connected to the input shaft, for example via a spline.
- a starting element is provided between the input shaft and output shaft or transmission shaft in order to enable torque transmission between the drive and the transmission even at different speeds.
- the axially parallel electrical machine is connected to the approach element via a traction drive.
- the traction drive is preferably designed as a chain drive with corresponding chain wheels on the electrical machine and starting element.
- the hybrid module is divided into at least three separate oil chambers in order to enable different lubrication and cooling conditions.
- at least one of the oil chambers is designed as a drying chamber, with components in the drying chamber that require little or no lubrication, such as the torsional damper, which is usually lubricated via its own grease chamber.
- a bearing plate is provided, which is arranged in the axial direction on the output side next to the torsion damper.
- the end shield takes on other tasks, which means that components can be saved.
- At least two of the further oil spaces are designed as wet spaces and are separate from one another, the wet spaces being able to differ in particular in terms of the lubricant or coolant and / or the degree of filling.
- One of the wet areas is formed by a housing of the starting element.
- the driving element is preferably completely filled with an oil.
- Preferred embodiments of a hybrid module are characterized in that the housing of the starting element is designed as a closed wet space on the drive side. Another wet space is preferably formed in the area of the traction drive, which is preferably lubricated via an oil mist, splash lubrication and / or a targeted oil supply. The further wet area is limited, for example, by the bearing plate and a housing of the hybrid module or a gear cover.
- Embodiments of a hybrid module are characterized in that the wet area in the housing of the starting element is connected to an oil circuit of the transmission. Due to the spatial proximity, the oil supply to the starting element is advantageously carried out via the oil circuit of the transmission, in particular since the output shaft of the starting element is connected to the transmission or a transmission shaft extends into the starting element.
- Hybrid modules according to embodiments are characterized in that the traction mechanism drive is connected to the housing of the starting element.
- a space-saving connection of the traction drive can be achieved, for example, by attaching the chain wheel directly to the housing of the starting element.
- the traction mechanism drive can also overlap with the housing in the axial direction.
- Embodiments of a hybrid module are characterized in that the central train drive is connected to the output side or to the input side of the starting element.
- the traction drive can be connected to the input or output side. If the starting element is used, for example, generally to improve the flow of force along the drive train, a connection to the input side is advantageous. If, on the other hand, the starting element can also be used to separate the internal combustion engine from the rest of the drive train, the traction drive and thus the electrical machine are connected to the The output side is advantageous because a separate disconnect clutch for purely electric travel can be omitted.
- Hybrid modules according to embodiments are characterized in that a separating clutch is provided between the torsional damper and the starting element.
- a separating clutch can be provided in order to separate the internal combustion engine from the rest of the drive train and to enable a purely electric drive via the electric machine.
- Preferred embodiments of a hybrid module with a separating clutch are characterized in that the separating clutch is designed as a claw clutch.
- a safe connection or disconnection can easily be achieved via a claw coupling.
- Another advantage of a claw coupling lies in the simple structure and the small installation space.
- Embodiments of a hybrid module are characterized in that the actuation of the separating clutch is arranged on the end shield.
- the actuation of an optional separating coupling is advantageously attached to the end shield, as a result of which supply and fastening of the actuation is simplified.
- a preferred claw coupling essentially comprises a sliding sleeve which produces the torque connection between the input shaft and the starting element via internal and external teeth.
- the actuation takes place, for example, via a ferromagnetic tie rod, which is axially fixed to the sliding sleeve, but can rotate relative to the sliding sleeve, and an electromagnetic coil that can pull the tie rod in the direction of the end shield.
- a ferromagnetic tie rod which is axially fixed to the sliding sleeve, but can rotate relative to the sliding sleeve, and an electromagnetic coil that can pull the tie rod in the direction of the end shield.
- actuation can also take place via a hydraulically actuated piston, in particular a special ring piston.
- One aspect of the invention is a hybrid module for arrangement between an internal combustion engine, an electric machine and a transmission, the hybrid module having an input shaft which can be connected to a torsional damper attached to the internal combustion engine, a starting element being provided, the The input shaft is connected to the input side of the starting element, a gear shaft being ver bindable to the output side of the starting element, the electric machine being axially parallel to the input shaft, and the electric machine being connected to a traction drive with the output side of the starting element , characterized in that a bearing plate is provided which is net angeord directly adjacent to the torsion damper, that a housing of the starting element has an axial section coaxially encompassing the input shaft, and that in the area of the bearing plate a plurality of coaxial seals ang is arranged to form a multi-stage sealing system.
- seals are preferably provided, which are arranged coaxially.
- the housing of the starting element advantageously has an axial section which runs coaxially with the input shaft and which can be used for guiding and receiving seals and / or for storage.
- Embodiments of a hybrid module are characterized in that between tween the end shield and the axial section of the housing of the starting element, a bearing is provided which supports the axial section in the radial direction, preferably in the radial and axial direction.
- a bearing is provided which supports the axial section in the radial direction, preferably in the radial and axial direction.
- the bearing is preferably also used for a bearing in an axial direction.
- a bearing in the axial direction has the advantage that any inflation of the starting element during operation takes place mainly on the transmission side, whereby an axial displacement of the traction drive, which is attached to the housing on the drive side, is avoided or minimized as far as possible. This can reduce a negative influence on the traction mechanism drive.
- the axial storage advantageously take place on the transmission side and the bearing on the bearing shield are only carried out radially supported.
- Embodiments of a hybrid module are characterized in that the starting element is designed as a hydrodynamically cooled clutch.
- a hydrodynamically cooled clutch is a multi-disc clutch in a fully felt oil chamber, in which an internal cooling oil flow is generated within the starting element, in particular via the disc shape and / or grooves in the friction surfaces.
- One advantage of the hydrodynamically cooled clutch is that it can be used flexibly on the one hand as a classic start-up element in conventional drives, as well as a disconnect clutch for purely electric driving and as a starter clutch to start (turn on) the combustion engine while driving. This saves additional corresponding components and the associated manufacturing and assembly costs and installation space.
- Embodiments of a hybrid module with a hydrodynamically cooled clutch are characterized in that the input shaft is connected to an inner disc carrier, and that the output shaft is non-rotatably connected to the housing of the starting element, which includes an outer disc carrier.
- the inner disk carrier represents the input side of the starting element and the traction mechanism can easily be connected to the housing as the output side.
- hybrid modules are characterized in that the sealing system has a first seal between the input shaft and the axial section in order to form an intermediate space that is depressurized compared to a filled wet space in the housing of the starting element, and that the sealing system has a second seal between the end shield and the input shaft has to seal the gap against a dry space, and that a third seal is provided between the end shield and the axial portion to the To seal the gap against another wet area in which the traction drive is arranged.
- this wet space has a higher pressure than the surrounding space. Since a relative movement can occur between the input shaft and the housing, or its axial section, of the starting element, a direct seal is difficult. A first seal is therefore provided, by means of which an unpressurized intermediate space is formed, in which there is no longer any increased pressure, but in which oil can still leak from the start-up element.
- a second seal is provided, which is preferably arranged between the bearing plate and the input shaft. This second seal can prevent any leakage oil from escaping from the space.
- a radial sealing ring for example, can be used as the second seal.
- a third seal between the end shield and an axial section of the housing of the starting element seals off a further wet area in which the traction mechanism is arranged from the gap.
- Embodiments of a hybrid module are preferably characterized in that the third seal is designed as a radial shaft sealing ring that seals in both directions.
- the third seal is designed as a radial shaft sealing ring that seals in both directions.
- Hybrid modules are characterized in that the input shaft has at least one relief opening in the region of the space in order to divert leakage oil radially inward, in particular via the transmission shaft, to a transmission sump. This avoids a pressure build-up in the intermediate space, which improves the function of the sealing system.
- Another aspect of the invention is a hybrid module for arrangement between an internal combustion engine, an electric machine and a transmission, the hybrid module having an input shaft which can be connected to a torsional damper attached to the internal combustion engine, a starting element being provided, with a Transmission shaft can be connected to the output side of the starting element, the electric machine being arranged axially parallel to the input shaft, and the electric machine being connected to the starting element with a traction drive, characterized in that a bearing plate is provided which is directly adjacent to the torsion damper is arranged that a separating clutch is seen between the input shaft and the starting element, and that the separating clutch is designed as a claw clutch.
- Embodiments of a hybrid module are characterized in that the starting element is designed as a torque converter.
- a hydrodynamic torque increase can be represented by a torque converter, which improves the starting performance of the starting element.
- the torque converter preferably has a bridging clutch in order to enable a direct connection between the input side and the output side after starting.
- an additional optional torsional damper can also be provided in the lock-up clutch in order to further dampen any torsional vibrations from the internal combustion engine and to increase driving comfort.
- the additional torsional damper can alternatively be dispensed with.
- Embodiments of a hybrid module with a torque converter are characterized in that a seal is provided between the end shield and the input shaft to seal another wet area from the dry area, and that the wet area of the housing of the starting element is closed on the drive side.
- a seal is provided to the further wet room in which the The traction drive is arranged to seal against the drive-side drying chamber. In terms of its arrangement, this corresponds to the second seal described above in a hydrodynamically cooled coupling, with the seal not taking place against an intermediate space but directly against the further wet space.
- the housing is completely closed on the drive side and represents the input side of the starting element. This means that only a transmission shaft or a non-rotatable area for a stator of the torque converter needs to be sealed.
- Embodiments of a hybrid module are characterized in that a housing of the hybrid module is made in one piece with a housing of the electrical machine. For precise positioning with respect to one another and to reduce the number of individual parts, the housing of the hybrid module can also accommodate the electric machine. Another advantage is that the additional wet space for the traction mechanism is located in a defined interior.
- Hybrid modules are characterized in that a housing of the hybrid module is designed separately from a housing of the electrical machine and these housings can be connected to one another. Due to a separate design, the size and complexity of the housing is reduced and, in addition, different electrical machines can be more easily connected to the uniform hybrid module, which makes different variants easier to implement.
- Embodiments of a hybrid module with separate housings for the hybrid module and the electric machine are characterized in that the relative position of the housings of the hybrid module and the electric machine can be changed via adjustment means in order to tension the traction mechanism.
- Tensioning means for the traction drive can be omitted if the housings are made separately and can be connected via adjustment means.
- the position of the electrical machine can be changed relatively via the setting means, so that the traction mechanism drive can be tensioned.
- the setting means can be designed via adjustable spacer sleeves or screws with or without a one-sided articulated connection of the housing or insertable intermediate elements.
- Embodiments of a hybrid module are characterized in that the housing of the hybrid module is formed separately from a housing of the transmission. This keeps the component size smaller. Another advantage is that a hybrid module can be connected to different transmission variants.
- Hybrid modules are characterized in that the housing of the hybrid module is designed in one piece with a housing of the transmission.
- the one-piece design of the housing reduces the number of components and makes installation in the vehicle easier.
