Definitions

  • the invention relates to a hybrid transmission and a drive train for a motor vehicle according to the preamble of claim 1 and claim 9.
  • Hybrid drive assemblies are known from the prior art, which have under the most diverse designs of hybrid transmissions.
  • Hybrid drive arrangements generally include an internal combustion engine and a hybrid transmission with a clutch device and at least one electrical rotary machine's.
  • Some such hybrid drive arrangements can realize a purely electric ferry operation.
  • a known configuration of a hybrid drive arrangement is referred to as a so-called P2 parallel hybrid.
  • This works with an electric rotary machine arranged in the torque transmission path between an internal combustion engine and a transmission.
  • a separating clutch enables the internal combustion engine to be coupled and uncoupled, so that when the internal combustion engine is decoupled, purely electric ferry operation can be carried out using the electric rotary machine.
  • EP 2 146 855 B1 discloses a hybrid drive system with such a configuration.
  • the hybrid drive systems that are also known also include those that have a dual-clutch transmission with two sub-transmissions for shifting.
  • This double-clutch transmission then comprises at least two partial clutches as clutch arrangements, with which the torque, starting from the internal combustion engine or from the rotary machine (electric machine), is routed via one of the two partial transmissions.
  • An example of such a hybrid drive system is known, for example, from WO 2019/242 795 A1.
  • a double clutch with a separating clutch is housed together in one housing in order to connect either a rotary machine or an internal combustion engine to the (partial) drive trains.
  • the Rota tion machine is radially spaced from the clutches and a gear train with the output side of the separating clutch to the internal combustion engine and the connected to both input sides of the respective clutch devices for coupling to the sub-transmissions.
  • WO 2019/242 795 A1 presents what is known as a triple clutch, in which all clutch units are provided in a common housing
  • WO 2005/085674 A1 discloses a dual clutch transmission to be constructed in such a way that the Coupling device of a sub-transmission is located on one axial side of the transmission, while the other coupling device is arranged on the axially opposite side of the transmission.
  • the object of the present invention is therefore to propose a hybrid transmission that can be assembled as simply as possible and a correspondingly simply assembled drive train for a motor vehicle, comprising a separating clutch, an electric rotary machine, a first clutch device and an output device of the hybrid transmission, which are connected or can be connected to one another in series are, wherein the first clutch device is arranged in a first torque transmission path and the hybrid transmission also has a second clutch device, which is also connected to the output device of the hybrid transmission, and in a parallel to the first torque transmission path second torque transmission path is arranged, wherein the first clutch device is spatially separated from the second clutch device and translation stages axially between the first clutch device and the second hitch be device ang are arranged, the separating clutch is arranged axially on the same side of the gear ratios as the first clutch device and the separating clutch and the first clutch device are provided in a common space of the hybrid transmission.
  • the separating clutch is, for example, a friction clutch for coupling an internal combustion engine to the transmission, while the rotary machine is in particular an electric machine or electric motor. Both the rotating machine and the internal combustion engine can transmit torque to an output device via the two clutch devices, optionally via gear ratios of a first and/or second sub-transmission. Wheels, axles or differentials, for example, can be considered as output devices.
  • the torque is routed via two parallel torque paths through two sub-transmissions with different ratios, which makes shifting under load possible, in particular.
  • the torque paths can also share transmission components such as spur gear teeth or planetary gear sets, but have at least sections that are assigned exclusively to at least one of the torque paths, ie partial transmissions.
  • gear ratios When gear ratios are discussed more generally here, they can be respective spur gear teeth, gear sets or planetary gear sets of one or more sub-transmissions.
  • the second clutch device for the gear ratios which can be assigned to a sub-transmission of a double hitch transmission, for example, is located here on one axial side of the gear ratios, while the other, first clutch device is on the other side of the gear ratios.
  • the transmission stages can also only be parts of respective partial transmissions, so that the second clutch device can be arranged axially between different transmission stages.
  • the first clutch device and the separating clutch for coupling to an internal combustion engine for example, are located in a common construction space, for example within a separate housing component that can be an integral part of a transmission housing, or is connected to it. This can in particular be a clutch bell.
  • the first clutch device is nested radially within the separating clutch, ie arranged such that this clutch system consisting of the separating clutch and the first clutch device can be manufactured as a testable subassembly and then finally plugged into counter-toothings on the part of the transmission. This enables a correspondingly simple assembly of this clutch system with the transmission.
  • the actuation means for the separating clutch and the first clutch device can then be arranged axially next to one another without the actuation means of one actuation means having to reach through the other actuation means.
  • the first clutch device has an input side and an output side
  • the separating clutch has an input side and an output side
  • the output side of the separating clutch at least partially represents the input side of the first clutch device and both the output side of the separating clutch and the input side of the first clutch device is connected or can be connected to a rotor of the rotary machine.
  • this connection can be made by means of a tooth system.
  • the toothing e.g. as a permanently connected gear wheel, can be an integral part of the clutch system and the clutch system can be installed by contacting this toothing with a counter-toothing.
  • the separating clutch and the first clutch device are multi-plate clutches, preferably wet multi-plate clutches, and the inner plate carrier of the separating clutch is the outer plate carrier of the first clutch device and forms a common plate carrier. In this way, a compact clutch system for installation in the Ge gear can be realized.
  • the separating clutch has an output side which is or can be connected to the second clutch device, preferably via a solid shaft.
  • This connection can also be made via gearing on the solid shaft and, for example, a driver ring on the part of the clutch system.
  • gearing on the solid shaft and, for example, a driver ring on the part of the clutch system.
  • a final connection of the clutch system to the transmission and the shaft arranged within the transmission on the input side of the second clutch device can be established.
  • the output side of the first clutch device can then further have a clutch hub with internal teeth, which is pushed onto external teeth of an egg ner, the solid shaft enclosing the hollow shaft for connection to translations in the transmission.
  • the clutch system can then be connected in a simple manner as a subassembly to the transmission.
  • the common disk carrier is coupled to a clutch rotor, which is connected or can be connected to the rotor of the rotary machine via a gear wheel.
  • the clutch rotor and gear wheel then represent components of the clutch system, which have one of the teeth for connection to the transmission.
  • the toothing can be used to contact an off-axis, i.e. radially offset gear wheel which is in contact with the rotor of the rotary machine, i.e. the electric motor.
  • the rotary machine itself is then arranged radially offset from the clutch rotor.
  • the hybrid transmission can also be designed in such a way that the separating clutch is actuated by means of a first piston and the first clutch device by means of a second piston, and the first piston, the second piston and the gear wheel are nested axially, so that the first piston lies axially between the second piston and the gear and is arranged axially between the separating clutch and the first hitch be device on the one hand and the gear on the other hand.
  • the pressure chamber of the first piston is formed between the first piston and the common disk carrier, while the pressure chamber of the second piston is formed between the second piston and an axial side of the gear wheel.
  • a Kupplungssys system can be formed in which the actuating forces are each performed via the common disk carrier and closed within the clutch system.
  • a sealing element for sealingly closing the pressure chamber of the first piston is placed between the gear wheel and the first piston Piston is provided.
  • a sealing running surface or a seal with a static sealing lip on the gear wheel side and a dynamic sealing lip on the piston side can be provided as the sealing element.
  • the gear wheel can have a groove on its radially inner side to accommodate the static part of the seal. This ensures a particularly simple construction of the clutch system.
