DEVICE FOR A HYBRID VEHICLE WITH A DUST RING BETWEEN AN ELECTRIC MACHINE AND A REACTION PLATE

摘要

The invention relates to a device for a motor vehicle transmission assembly, comprising: - an electric machine (3) comprising a rotor (9) able to rotate about an axis X and a stator (8), the rotor (9) being arranged inside the stator (8), separated from the stator (8) by an annular air gap space (300), - a clutch (2) coaxial with the electric machine comprising a reaction plate (10), the reaction plate (10) rotating as one with the rotor (9) and being positioned an axial distance from said rotor (9) in order to leave space between the electric machine (3) and the reaction plate (10), said assembly being fitted with a dust ring (301) positioned axially in the space between the electric machine (3) and the reaction plate (10) and extending radially far enough to cover the annular air gap space (300).
