Abstract
A synchronizing device for a transmission has a sliding sleeve comprising an internal toothing with a plurality of sliding sleeve teeth and a clutch body of a gear wheel, comprising n external toothing with a plurality of clutch body teeth formed without meshing bevel at their axial tooth end close to the sliding teeth, into which the internal toothing of the sliding sleeve can engage. A synchronizing unit is provided which can block axial movement of the sliding sleeve, until the speeds of the sliding sleeve and clutch body are adapted. During operation, an axial force of the sliding sleeve against the clutch body is built up and a speed difference between the sliding sleeve and the clutch body is produced, so that the end faces of the sliding sleeve teeth and the clutch body teeth slide along each other, and the sliding sleeve teeth finally are meshed between the clutch body teeth.
