Problems solved by technology

This axial continuity of the elements of the transmission line does not meet the current market demand for compactness
[0007] Devices are also known in which the fluid supply for cooling and / or actuating the clutch, in particular the input clutch, is on the gearbox side, in particular via one of the input shafts of the gearbox, but this increases the complexity of the gearbox manufacture sex

Embodiment Construction

[0050] figure 1 A torque transmitting device 1 is shown comprising:

[0051] - a first torque input element 2, rotating about an axis of rotation X, rotatably coupled to the crankshaft of an internal combustion engine (not shown),

[0052] - a first torque input element 4,

[0053] - a second torque output member 6, rotatably coupled to the first input shaft 6a of the gearbox,

[0054] - a third torque output member 7, rotatably coupled to the second input shaft 7a of the gearbox, and

[0055] Within the meaning of the invention, the second torque input element 5 is rotatably coupled to the first torque output element 4 and is arranged between the torque output element 2 and the second and third torque output elements 6 , 7 .

[0056] In the example considered, the third output element 7 is arranged parallel to the second output element 6 in the direction of torque transmission. Each of these elements rotates about the axis of rotation X of the device.

[0057] The second...

Abstract

Disclosed is a torque transmission device (1), in particular for a motor vehicle, comprising: - a first torque input element (2) rotating about an axis X, capable of being coupled to rotate with a crankshaft of a heat engine, comprising a rear portion (2a) and a front portion (2b), - a first torque output element (4), - an input clutch (10) selectively coupling, by friction, the torque input element (2) and torque output element (4), - an actuating system (20) associated with the input clutch (10) comprising a pressure chamber (21) and an axially movable piston (22), - a protective casing (27) designed to at least partially enclose the torque input element (2), the torque output element (4), the input clutch (10) and the actuating system (20), the casing (27) comprising an inner wall (28) extending axially around the axis X and a fluid passage network (80) designed to supply fluid to the actuating system (20), wherein said rear portion (2a) is arranged radially outside and inside the internal wall (28).

Description

technical field [0001] The invention relates to the field of transmissions for motor vehicles. The invention relates in particular to a torque transmitting device intended to be arranged in a drive train of a motor vehicle, between an internal combustion engine and a gearbox. [0002] The invention relates in particular to a torque transmission device for a hybrid vehicle in which a rotating electrical machine is arranged in a drive train. Background technique [0003] It is known in the prior art that a hybrid vehicle comprises a torque transmitting device arranged between an internal combustion engine and a gearbox, a rotating electric machine, and a clutch for operating the clutch to rotatably connect the crankshaft of the internal combustion engine to the rotor of the rotating electric machine. Components that are joined or disjointed. Therefore, it is possible to switch off the internal combustion engine every time the vehicle stops and restart the vehicle using the r...
