Abstract

A planetary carrier includes an input-side hub, an input-side outer leg, an output-side leg including an output-side axle seat for receiving an output-side end of a planetary axle, a web connecting the input-side outer leg with the output-side leg and an input-side inner leg arranged in parallel to the input-side outer leg. The input-side inner leg includes an input-side axle seat for receiving an input-side end of the planetary axle.

Claims (12)

1. A planetary carrier, comprising:

an input-side hub;

an input-side outer leg;

an output-side leg including an output-side axle seat for receiving an output-side end of a planetary axle;

a web connecting the input-side outer leg with the output-side leg; and

an input-side inner leg arranged in parallel to the input-side outer leg, said input-side inner leg including an input-side axle seat for receiving an input-side end of the planetary axle.

2. The planetary carrier of claim 1 , wherein the input-side inner leg is fastened to the input-side hub and/or to the input-side outer leg and/or to the web.

3. The planetary carrier of claim 1 , wherein a torsional stiffness of an inner load path, which leads from the input-side hub to the input-side axle seat, is adjusted to a torsional stiffness of an outer load path, which leads from an output-side hub to the output-side axle seat, such that under load a defined distortion of the input-side axle seat is established relative to the output-side axle seat.

4. The planetary carrier of claim 1 , wherein the planetary carrier is assembled from a number of individual parts.

5. The planetary carrier of claim 4 , wherein the individual parts of the planetary carrier are assembled by welded connections or screw connections.

6. The planetary carrier of claim 1 , wherein the planetary carrier is assembled from a number of individual parts by welded connections, with relief notches being arranged along a partial length of the welded connections.

7. The planetary carrier of claim 1 , wherein the web is formed by a pipe with cutouts for planet wheels of the planetary carrier.
