Definitions

  • the invention relates to a hybrid module for a drive train of a motor vehicle, such as a car, a truck, bus or other commercial vehicle, with an input shaft that can be connected to an output shaft of an internal combustion engine, an electrical machine, a carrier rotatably coupled to a rotor of the electrical machine, a Acting between the input shaft and the carrier is a set separating clutch, the separating clutch with several friction elements being arranged ra dial within a sleeve-shaped torque transmission area of the carrier coupled to the rotor, as well as two each with one of their coupling components rotatably connected to the carrier forming a double clutch Ending partial clutches, both a first partial clutch and a second partial clutch having a plurality of friction elements arranged radially within the torque transmission area.
  • the hybrid module according to the preamble is implemented as a unit that has an electric motor with three clutches (separating clutch and partial clutches).
  • the invention also relates to a drive train equipped with this hybrid module.
  • Hybrid modules of the generic type are already sufficiently known from the prior art.
  • WO 2019/015714 A1 discloses a hybrid module with a rotary leadthrough.
  • This design makes it possible to equip the separating clutch with thinner friction elements or even with a smaller number of friction elements than before. This in turn enables a significantly more compact axial structure of the hybrid module.
  • an inner diameter of the rotor namely an inner diameter of a laminated rotor core forming the rotor, as it is fastened on a radia len outer side of the torque transmission area, is greater than 182 mm, more preferably greater than 200 mm. This achieves a clever compromise between axial compactness and radial compactness, since the individual friction elements for transmitting particularly high torques are designed to be as large as possible with regard to their diameter.
  • the friction elements of all clutches are all located in the axial direction within the rotor and are thus arranged in the axial direction at the level of the torque transmission area.
  • the friction elements of the separating clutch and the first partial clutch are covered as a whole in the axial direction by the torque transmission area.
  • the friction elements of the second partial clutch are also all covered radially from the outside axially by the torque transmission area.
  • the friction elements of the separating clutch are arranged at the same radial height as the friction elements of the first partial clutch. This is because the torque transmission area is particularly easy to produce.
  • At least one first friction element (preferably several first friction elements) of the separating clutch which is (are) received on a (first) toothing area of a first disk carrier, as well as several second friction elements of the first partial clutch, which are received on a (second) toothed area of a second disk carrier, is arranged at the same radial height.
  • the separating clutch has a smaller number of friction elements than the first partial clutch and / or than the second partial clutch, it can be adapted particularly skillfully to the respective torques to be transmitted while realizing the smallest possible axial installation space.
  • the number of friction elements of the separating clutch is less than half the number of friction elements of the first partial clutch and / or less than half the number of friction elements of the second partial clutch development.
  • the separating clutch has at least one first friction element (preferably several first friction elements) and at least one second Rei element (preferably several second friction elements).
  • the separating clutch includes a first clutch component comprising at least one first friction element (preferably several first friction elements), which is non-rotatably connected to the input shaft, as well as at least one second friction element (preferably several second friction elements) second clutch component attached to the carrier / torque transmission area.
  • this first partial clutch has a first clutch component comprising a plurality of first friction elements, which is connected non-rotatably to the carrier / torque transmission area, and a plurality of second friction elements comprising the second clutch component, which preferably has is further connected to a transmission input shaft.
  • the at least one first friction element of the separating clutch and the second Reibele elements of the first partial clutch are advantageously designed as identical parts.
  • the at least one second friction element of the separating clutch and the first friction elements of the first partial clutch are also advantageously designed as identical parts. This further reduces the manufacturing effort.
  • the at least one first friction element of the separating clutch is arranged at the same radial height as the second friction elements of the first partial clutch, it is furthermore useful if a (first) disk carrier of the first clutch component is part of the separating clutch and a (second) disk carrier of the second clutch component of the first partial clutch are dimensioned identically with regard to their toothed areas that hold the corresponding friction elements in a rotationally fixed manner.
  • a (first) disk carrier of the first clutch component is part of the separating clutch and a (second) disk carrier of the second clutch component of the first partial clutch are dimensioned identically with regard to their toothed areas that hold the corresponding friction elements in a rotationally fixed manner.
  • the formation of both toothing areas with the same diameter / pitch circle diameter is ideal. Due to the identical toothing, the same roller burnishing tool can be used when making Her, which also reduces the Her alternating effort.
  • the manufacturing effort is reduced if the separating clutch and the first partial clutch each have a pressure ring and these pressure rings of the separating clutch and the first partial clutch are implemented as identical parts. Also, locking rings, which each support one of the pressure rings, are preferred as identical parts. This further reduces the manufacturing effort.
  • the axi ale compact design is further improved.
  • the invention relates to a drive train for a motor vehicle, with the sem hybrid module according to the invention according to at least one of the embodiments described above.
  • the inventive arrangement of a three-way clutch is used to reduce axial installation space in particular.
  • a first partial clutch and a second partial clutch, which together form a double clutch, are nested radially with respect to one another; a separating clutch is arranged axially next to the first partial clutch.
  • the separating clutch is therefore relatively large in the radial direction and requires relatively few friction elements / friction plates / friction plates to transmit a high torque, which results in a significant reduction in the axial installation space.

  • the number of friction elements 14a, 14b of the first partial clutch 11 is higher than the number of friction elements 8a, 8b of the separating clutch 7.
  • a total of six first friction elements 14a are provided.
  • Six second friction elements 14b are also provided.
  • the friction elements 14a, 14b of the first partial clutch 11 are arranged between a second pressure plate 27b and a second pressure ring 28b.
  • the second pressure ring 28b is axially supported by means of a second securing ring 29b.
  • the first and second pressure rings 28a and 28b are implemented as identical parts.
  • the two locking rings 29a and 29b are also implemented as identical parts.
  • it is advantageous if the first friction elements 8a of the separating clutch 7 and the two th friction elements 14b of the first partial clutch 11 are implemented as identical parts.
  • the second friction elements 8b of the separating clutch 7 and the first Rei belemente 14a of the first partial clutch 11 are implemented as identical parts.

  • the clutches K1 (first partial clutch 11) and K2 (second partial clutch 12) are nested radially and the K0 (separating clutch 7) is arranged axially next to the K1.
  • the K0 which typically needs to transmit a lower torque than the two partial clutches K1, K2, only requires a few friction plates (first and second friction elements 8a, 8b) to transmit the torque, which leads to a significant reduction in the axial space requirement .
  • All clutches 7, 11, 12 are arranged inside the E-machine rotor 5.
  • the clutch K2 is arranged radially inside the clutch K1.
  • the actuation of the two clutches K1, K2 is located radially within the hitch K2.
  • the radial nesting of the clutches K1 and K2 has the advantage that, as in the case of radially nested double clutches, during the manufacture of the disks 14a, 14b; 15a, 15b an internal waste use becomes possible:
  • the punching waste from the production of the K1 (/ the friction elements 14a, 14b) is used for the K2 (/ the friction elements 15a, 15b).
  • K1 and K2 can be cooled with the same cooling oil flow.
  • the axial arrangement of the K0 next to the K1 not only has the above-mentioned advantage of increasing axial installation space but also makes it possible to use identical parts:
  • the steel plates of the K1 and the K0 (second friction elements 8b and first friction elements 14a) are identical.
  • the lining disks of the K1 and the K0 are also of identical design.
  • the inner disk carrier 17, 18 of the K1 and the KO can possibly use the same roller burnishing tool.
  • the pressure rings 28a, 28b of the K1 and KO are identical.
  • the retaining rings 29a, 29b of the K1 and KO are identical.
