  • the output shaft (6) extends correspondingly far into the hollow damper hub (3), so that the front bearing (16) partly overlaps with the vibration damper (12).
  • the central hub (4) is formed correspondingly shorter compared to the example shown in Fig. 1.
  • a modified geometry of the central hub (4) and / or the housing (1) on a bearing between the central hub (4) and damper hub (3) are dispensed with and they are independently supported on the housing (1) and the output shaft (6).
  • the bearing (8.3) is also designed in this embodiment as a ball bearing to accommodate both radial and axial bearing forces can.
  • the bearing (8.3) is also arranged axially further away from the internal combustion engine compared to the other embodiment shown. As a result, overlaps the bearing (8.3) only slightly with the bearing (7) between damper hub (3) and housing (1).
  • the bearing (10.1) between the central hub (4) and the output shaft (6) is also located axially further away from the engine, which is why it still partially overlaps with the bearing (8.3) between the central hub (4) and damper hub (3), however no longer with the bearing (7) between damper hub (3) and housing (1).

Abstract

L'invention concerne un module hybride comprenant un moyeu d'amortissement (3) relié à un moteur à combustion interne, un carter (1), un embrayage (11), un moteur électrique (2) comprenant un rotor (2.2) et un stator (2.1) relié au carter (1), un convertisseur de couple (5) comportant un boîtier de convertisseur (5.1) relié à un moyeu central (4) et un arbre de turbine (5.2), ainsi qu'un arbre de sortie (6), le rotor (2.2) du moteur électrique (2) étant relié au moyeu central (4), au boîtier de convertisseur (5.1) ou au moyeu d'amortissement (3), l'arbre de turbine (5.2) étant relié solidaire en rotation à l'arbre de sortie (6), l'embrayage (11) étant agencé entre le moyeu d'amortissement (3) et le convertisseur de couple (5), et le moyeu d'amortissement (3) étant relié au moteur à combustion interne par l'intermédiaire d'un amortisseur de vibration (12). Cette invention est caractérisée en ce qu'un palier antérieur (8.1 ; 16) du moyeu d'amortissement (3) est prévu de manière à assurer un support dans la direction radiale, et en ce que ce palier antérieur (8.1 ; 16) est agencé de manière chevauchante, au moins partiellement avec l'amortisseur de vibration (12).
