- the powertrain 10 is formed of a set of modules, here the motor 12, the inverter 13 and the gearbox 14, which are rigidly connected to each other.
- the powertrain 10 forms a together solidarity that is likely to be carried a block.
- the powertrain 10 is generally supported by at least one structural element 34 of the motor vehicle, for example by a cradle, through a plurality of support devices 36 rigid.
- a first end of the rigid support 36 is fixed to the power unit 10 while an opposite end is fixed to a suspension pad (not shown) of the support member 36 via a damping member 38, generally a ring of elastomeric material also known as "silentbloc".
- a damping member 38 generally a ring of elastomeric material also known as "silentbloc".
- the powertrain 10 is here arranged so that the long transmission shaft 22 is arranged longitudinally opposite a suspension stud of the structural element 36. As a result, it is not easy to arranging a support device 36 on the wall vis-à-vis the powertrain without interfering with the passage of the shaft 22 long transmission.
- the invention proposes the support device 40 which is illustrated in FIGS. 2 to 4.
- the support device 40 includes a support arm 42 which extends here in a longitudinal direction from a rear end to a front end.
- the support arm 42 here has a transverse width less than its vertical height.
- the support device 40 also comprises a fastening flange 44 which is arranged at a first end of the support arm 42, here at the front end.
- the sole plate 44 has the form of a transverse vertical plate whose opposite face to the arm 42 is intended to be plated longitudinally against an associated face of the powertrain 10, as will be explained in more detail later.
- the sole 44 is intended to be fixed rigidly to the power unit 10.
- the sole 44 is here crossed by several orifices. 46 fixing, here three in number, which are intended to receive a threaded rod, for example a screw or a stud.
- a transverse main axis suspension ring 48 "A" which is arranged at a second end, here the rear end, of the support arm 42.
- the ring is intended to be hooked to a stud (not shown) for suspending the structural element with the interposition of a damping member 50, here a ring comprising elastomeric material.
- the support device 40 is thus intended to be fixed to the vehicle structural element by interlocking the ring 48 with the associated suspension stud.
- the support device 40 is made in one piece. This means that the arm 42, the sole 44 and the ring 48 are made in one piece.
- the device is here made in one piece by molding and machining of said part.
- the support device 40 is for example made of a metallic material such as steel, cast iron or aluminum.
- the support arm 42 comprises a bearing 52 relay which is intended to be traversed by the shaft 22 of long transmission to support it.
- the relay bearing 52 is designed to house a guide bearing (not shown) of the transmission shaft 22 of the powertrain 10.
- the relay bearing 52 is formed by an orifice made in an intermediate portion 54 of the arm 42.
- the orifice is delimited by a closed inner cylindrical wall 56 of main axis "B" which is here transverse.
- the relay bearing is open radially with an opening large enough to insert the transmission shaft longitudinally. The opening is then intended to be closed by a reported cap.
- the main axis "A" of the suspension ring 48 is here parallel to the main axis "B" of the relay bearing 52.
- the intermediate portion 54 is interposed longitudinally between the sole 44 and a longitudinal end section which comprises the suspension ring 48. As is particularly visible in Figure 2, the relay bearing 52 is arranged longitudinally closer to the sole 44 than the ring 48 suspension.

- the flange 44 is here fixed by means of three fixing screws 61 passed through the orifices 46 and screwed into corresponding threads of the wall 60 of the engine 12.
- the long transmission shaft 22 is arranged along said wall 60, a longitudinal space being reserved between the transmission shaft 22 and the wall 60 to allow rotation of the shaft 22.
- a guide bearing (not shown) is mounted around the long transmission shaft 22.
- the long transmission shaft 22 is inserted transversely into the relay bearing 52 in the direction of the differential of the gearbox 14, until the guide bearing is housed in the relay bearing 52.
- the inner wall 56 of the relay bearing 52 has an annular shoulder 62 against which an outer ring of the guide bearing is intended to abut transversely.
- An annular cover 64 is then fixed, here by screwing, on the arm 42 of the support device 40 to close the relay bearing 52 and thus prevent the guide rolling out.
- an accessory here the charger 13 is supported in part by the upper rib 58A of the device 40 support.
