Embodiment Construction

[0069] In a non-limiting way and for ease of understanding, the remainder of the description and claims will use the terms "front" or "rear" according to the direction relative to the axial orientation determined by the main axis of rotation O of the transmission of the motor vehicle and the terms "inner / inner" or "outer / outer" relative to the axis O and in a radial orientation orthogonal to said axial orientation.

[0070] Figures 1 to 2 A first embodiment of a disc holder for a wet double clutch mechanism 1 is shown. The wet double clutch mechanism 1 has a main axis of rotation O.

[0071] A wet dual clutch mechanism 1 for a torque transmission system comprises at least one input member 2 about an axis O, which is connected in rotation to a drive shaft (not shown). The input element 2 is located behind the wet double clutch mechanism 1 .

[0072] In a first embodiment, the generally “L” shaped input element 2 comprises a radially oriented portion formed by the input web ...

Abstract

The invention concerns a disc holder for a wet clutch, comprising: a cylindrical hub (131, 231) with axis of rotation O, a disc support (132, 232) having a shape rotationally symmetric about the axisO, the disc support (132, 232) being in axial contact with the hub (131, 231), the hub (131, 231) and the disc support (132, 232) being assembled by means of friction welding.

Description

technical field [0001] The present invention relates to a disc holder for a wet clutch, and to a wet clutch mechanism including the disc holder, and more particularly to a wet double clutch mechanism including the disc holder. The invention also relates to a method for manufacturing such a disc holder. Background technique [0002] Such a wet clutch mechanism is intended to form part of a torque transmission system, in particular for motor vehicles or vehicles known as industrial vehicles, such as heavy goods vehicles, public transport or agricultural vehicles. [0003] Patent application WO2015 / 000482A1 discloses a wet dual clutch mechanism for a motor vehicle comprising a torque input device intended to be coupled to a crankshaft, a first torque output disc retainer connected to a first gearbox shaft, a first torque output disc retainer connected to a second A second torque output disc holder for the two gearbox shafts, an axial bearing arranged between the torque input d...
