1. A synchronizer hub for a gearbox synchronization device of a manual gearbox, said synchronizer hub comprising
a base body, which comprises a radially outer peripheral surface and two axial end faces, which adjoin the peripheral surface, an external tooth system arranged on the peripheral surface with teeth pointing radially outwards, at least one recess in the peripheral surface and interrupting the external tooth system, an annular groove arranged in a first axial end face of the two axial end faces and radially inward of the external tooth system, the annular groove also being interrupted by the at least one recess, and a plurality of segments on the first axial end face, said segments being arranged next to the at least one recess and extending in a radial direction into an area of the annular groove and partly overlapping the annular groove, wherein a first tooth of the teeth is disposed next to the at least one recess, wherein on the peripheral surface between the at least one recess and the first tooth a first tab is arranged which forms an axial stop for a sliding sleeve, wherein in a first direction a radial height of the first tab forming a raised area relative to the external tooth system is at least partly higher than a tooth height of the teeth of the external tooth system in the first direction, wherein the raised area of the first tab only extends partly over a width of the external tooth system in an axial direction, and wherein a remaining part of the first tab forms a partial tooth of the external tooth system. |
