A drive arrangement for auxiliary equipment of an engine includes an epicyclical gear having a sun gear, a ring gear and a planet carrier. A first component is connected to the engine, a second component is connected to a first electric machine, and a third component is connected to the auxiliary equipment. The first component is guided in rotation on the engine block and includes a rigid assembly which supports the other two components. The stator of the first electric machine is fixed on a holder. The holder is guided in rotation directly or indirectly on the first component rigid assembly, and the first component is guided in rotation on the engine block independently from the holder.

1. Drive arrangement at least one auxiliary equipment of an internal combustion engine having an engine block and a rotating output member, wherein the drive arrangement comprises an epicyclical gear having three main components comprising a sun gear, a ring gear and a planet carrier, and wherein: a first component of the components adapted to be connected to the engine rotating output member,a second component of the components adapted to be connected to the rotor of a first electric machine having also a stator, anda third component of the components adapted to be connected to the at least one auxiliary equipment, wherein the first component is guided in rotation by a strict pivot connection on the engine block and comprises a rigid assembly which supports the other two components,wherein the stator of the first electric machine is fixed on a holder, the holder being guided in rotation by a strict pivot connection directly or indirectly on the first component rigid assembly, and the first component is guided in rotation on the engine block independently from the holder, and wherein the holder is mounted indirectly on the rigid assembly through another component of the epicyclical gear, the strict pivot connection of the holder on that other component being located axially substantially together with, and around, the strict pivot connection of that other component on the rigid assembly. 2. Drive arrangement according to claim 1, wherein the second and third main components are each mounted directly or indirectly on the first component rigid assembly through a strict pivot connection. 3. Drive arrangement according to claim 2, wherein the second and/or the third main component is/are mounted directly on the first component rigid assembly through a strict pivot connection. 4. Drive arrangement according to claim 1, wherein the holder is locked in rotation around the main axis by a link connected to a static part. 5. Drive arrangement according to claim 4, wherein the holder is locked in rotation around the main axis by a link connected directly or indirectly to the engine block, and in that the link connection is less rigid than the direct or indirect pivot connection of the holder to the engine block. 6. Drive arrangement according to claim 1, comprising a second electric machine which is connected to the third coupling. 7. Drive arrangement according to claim 6, wherein the second electric machine comprises a stator which is fixed on the same holder which carries the stator of the first electric machine. 8. Drive arrangement according to claim 1, wherein the rigid assembly of the first component is directly attached as an extension to the engine output shaft. 9. Drive arrangement according to claim 1, wherein the planet carrier has at least one radial extension which carries at least one planet gear, in that the sun gear and ring gear are guided in rotation with respect to the planet carrier through a respective strict pivot portion, and in that the strict pivot portions of the sun gear and of the ring gear are respectively substantially located axially on one side and on the other side of the radial extension of the planet carrier. 10. Drive arrangement according to claim 1, wherein the rigid assembly comprises a part in the form of a shaft extending along an axis on which are formed pivot connection portions for supporting directly or indirectly all the other components of the drive assembly in a strict pivot connection. 11. Drive arrangement according to claim 1, wherein the at least one auxiliary equipment comprises an engine cooling fan. 12. Drive arrangement for at least one auxiliary equipment of an internal combustion engine having an engine block and a rotating output member, wherein the drive arrangement comprises an epicyclical gear having three main components comprising a sun gear, a ring gear and a planet carrier, and wherein: a first component of the components adapted to be connected to the engine rotating output member,a second component of the components adapted to be connected to the rotor of a first electric machine having also a stator, anda third component of the components adapted to be connected to the at least one auxiliary equipment, wherein the first component is guided in rotation by a strict pivot connection on the engine block and comprises a rigid assembly which supports the other two components,wherein the stator of the first electric machine is fixed on a holder, the holder being guided in rotation by a strict pivot connection directly or indirectly on the first component rigid assembly, and the first component is guided in rotation on the engine block independently from the holder,wherein the second component is provided with a mechanical lock which can be controlled to lock the rotation of the second component around the axis of the epicyclical gear. 13. Drive arrangement according to claim 12, wherein the mechanical lock locks the second component to the holder on which the stator of the first electric machine is fixed.
