Abstract

An axial mounting of the planetary gearwheels of a planetary gearset having a sun gear that meshes with at least one planetary gearwheel mounted on a planetary bolt that is supported on the planetary carrier. The at least one planetary gearwheel meshes with a ring gear. At least one check-plate, which has a hole for the planetary bolt and which is positioned on one side of the planetary gearwheel between the planetary gearwheel and the planetary carrier, is associated with each planetary gearwheel. The check-plate is completely flat and is axially symmetrical relative to its longitudinal and transverse axes. The at least one check-plate has two wings that extend in the longitudinal direction, which are positioned in recesses formed in the planetary carrier, when the check-plate is in the installed condition, to secure the check-plate against rotation. The check-plate is fixed relative to the planetary carrier.
