Abstract
In a planetary gear (1) with an axially displaceable ring wheel (24), which can be coupled together with coupling rings (10,19) on either side of the planetary gear (1), synchronization rings (16,23) are arranged with external locking teeth. The ring wheel (24) is designed at its axial ends with a number of recesses (30), each accommodating locking bodies (31) which are spring-loaded in the radial direction and which bear against the synchronization rings (16,23) and which, during gear change movements, come to bear against shoulders (38) on the synchronization rings (16,23) in order to transmit axial force action to the synchronization ring (16,23) in question.
