Abstract
A securing arrangement for planet bolts in planetary gear change-speed transmissions, especially those for motor vehicles, in which all planet bolts are secured against axial displacement on one side by means of a common sheet metal locking plate adapted to be fixed at the planet gear carrier. Each planet bolt is provided on its side facing the locking plate with an annular groove for mounting therein a securing ring while the bores in the planet gear carrier intended for the accommodation of the planet bolts are enlarged on the side facing the locking plate into an axial groove open toward the outside so that after the insertion of the bolts together with the securing rings, the locking plate can be mounted axially over all bolts.
