摘要： Parking detent pawls are known which are suitable for securely holding a vehicle in a parked state. The aim of the invention is to provide a detent pawl for a parking lock which is characterized by a high degree of operational reliability. For this purpose, a method is proposed for producing a detent pawl with a latching section for engaging into a locking toothing, a support section for rotatably supporting the detent pawl about a rotational axis, and a locking section for resting against a locking bolt which can be moved along the detent pawl, having the following steps: providing a detent pawl blank; providing a shaping tool with a shaping contour, said shaping contour having a load section and a guide section; and shaping the detent pawl blank in a shaping direction by means of the shaping tool, wherein a depression for receiving the locking bolt is produced on the locking section, the load section defines a load region of the depression for supporting the locking bolt in a locking position, and the guide section defines a guide region of the depression for guiding the locking bolt during an actuation movement.

摘要： 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.
