Embodiment Construction

[0042] In the description and claims, the terms "outer," "inner," "front," "rear," and the orientations "axial" and "radial" will be used to designate transmissions according to the definitions given in the description. The components of the component.

[0043] By convention, the "radial" orientation is at right angles to the axis X that determines the rotation of the "axial" oriented assembly. The "circumferential" or "tangential" orientation is at right angles to the axis X of the assembly, and at right angles to the radial direction.

[0044] The terms "outer" and "inner" are used to define the relative position of one element with respect to another, according to the radial direction, with reference to the axis X, and elements closer to the axis are thus considered inner, with respect to being positioned radially Outer elements on the perimeter. The terms "front" and "rear" are used to define the relative position of elements with respect to each other in the axial direc...

Abstract

The invention relates to a transmission assembly for a motor vehicle, intended to be arranged between an internal combustion engine and a gearbox and capable of transmitting torque between the crankshaft of the internal combustion engine and the input shaft of the gearbox, said assembly comprising: an electric motor (3), comprising an outer stator (8) and an inner rotor (9), which are separated by an annular air gap space (300); and two dry clutches (1, 2), the two Dry clutches are arranged axially on both sides of said electric machine (3) on the engine side and on the gearbox side respectively; the clutch (1) on the engine side is arranged such that when in the engaged position it is in the Torque is transferred between the crankshaft of the internal combustion engine and the rotor (9) and the clutch (2) on the gearbox side is arranged such that when in the engaged position it is transferred between the rotor (9) and the input shaft of the gearbox Torque; where the rotor (9) is fitted with permanent magnets mounted on the outer periphery of the rotor (9) and introduced into the annular air gap space (300).

Description

technical field [0001] The invention relates to the field of transmission components for motor vehicles. In particular, the invention relates to a transmission assembly designed to be arranged between an internal combustion engine and a gearbox of a motor vehicle. [0002] In particular, the invention relates to a transmission assembly for a motor vehicle of the hybrid type, in which an electric machine is arranged in the drive train between the engine and the gearbox. Background technique [0003] A transmission assembly for a hybrid motor vehicle is known, comprising two clutches and an electric machine arranged between the vehicle's internal combustion engine and its gearbox. An assembly of this type is described, for example, in document FR 2830589 . Each clutch includes a friction disc, a clutch stop, a reaction plate and a clutch mechanism including a pressure plate mounted relative to the reaction plate with the friction disc clamped between the pressure plate and t...
