Synchronising device

A synchronising device for synchronising a first rotatable part with a second rotatable part adjacent to the first rotatable part, wherein the synchronising device comprises:

• a first rotatable part provided with an engaging sleeve, and
• a second rotatable part provided with a synchroniser ring, wherein the engaging sleeve is
• provided with a first set of internal teeth enabling a rotationally fix and axially displaceable arrangement upon the first rotatable part,
• provided with a first conical friction surface, and
• is adapted to be positioned in a first and a second axial position, wherein in the first axial position the first set of internal teeth engages only with the first rotatable part and in the second axial position, the first set of internal teeth engages with both the first and the second rotatable part, wherein the synchroniser ring is
• provided with a mating conical friction surface, wherein the first conical friction surface and the mating conical friction surface are adapted to interact with each other in order to synchronise the engaging sleeve and the synchroniser ring of the first and second rotatable parts,
• provided with a second set of internal teeth enabling an arrangement upon the second rotatable part, wherein the second set of internal teeth is provided with a first blocking surface adapted to interact with a corresponding second blocking surface upon the second rotatable part,
• adapted to be positioned in a first and a second axial position, wherein in the first axial position the blocking surfaces can interact with each other and the second axial position enables engagement of the engaging sleeve with the second rotatable part, and
• adapted to be positioned in a first and a second rotational position relative to the second rotatable part, wherein the first rotational position enables the blocking surfaces to interact with each other and the second rotational position enables an axial displacement of the synchroniser ring, wherein
• the synchronising device further comprises at least an axial positioning resilient member arranged relative to the synchroniser ring and the second rotatable part such that the axial positioning resilient member exerts a force upon the synchroniser ring in a direction towards the first axial position of the synchroniser ring,
• wherein the axial positioning resilient member acts upon an axial reaction surface of the second rotatable part, and the axial reaction surface is provided upon a first external tooth of the second rotatable part.
