Abstract
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.
Claims13
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, and
- a 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.
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, and
- a 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.
