Abstract
A planet carrier (2) for a gearbox, especially an automatic or power shift gearbox, is provided, including at least one planet gear (4) which is connected to a sun gear and a rotor wheel. The planet carrier is embodied in two parts and is made in two bodies (11, 12) which are formed with a step-like shape and which are arranged one within the other. The internal diameter of the axially extending segments of the external body (11) is adapted to the external diameters of the internal body (12). The bodies are positioned in a precise manner in relation to each other during construction. The individual components can be produced in a simple manner by shaping the sheet steel in a non-cutting manner.
