A synchronization device for a manual transmission has a sliding sleeve (112), which has an inner toothing with a plurality of sliding sleeve teeth (118), and a coupling body of a gear wheel, which has an outer toothing with a plurality of coupling body teeth (120), into which the inner toothing of the sliding sleeve (112) can engage. The invention relates to a synchronization unit which is designed to block an axial movement of the sliding sleeve (112), the coupling body teeth (120) having no oblique meshing portion at the axial tooth end (130) close to the sliding sleeve teeth (118). During shifting, the rotational speed of the sliding sleeve (112) and that of the coupling body are adjusted to each other. An axial force (F) of the sliding sleeve against the coupling body builds up and a rotational speed difference between the sliding sleeve (112) and the coupling body is produced so that the end faces (136, 134) of the sliding sleeve teeth (118) and of the coupling body teeth (120) glide along each other, and the sliding sleeve teeth (118) eventually mesh with the coupling body teeth (120). |
