## Abstract

A planetary axle for a planetary gearbox can be constructed analogously to a transverse link axle and/or a thrust/flexural link axle and/or a longitudinal link axle for use in the automotive industry. The planetary axle includes a clamping area for clamping of the planetary axle in a side of a planetary carrier, a bearing seat area for receiving a planetary bearing, and a link area disposed between the clamping area and the bearing seat area.

## Claims

### Claim 1

A planetary axle for a planetary gearbox for use in the automotive industry, said planetary axle comprising:
a clamping area for clamping of the planetary axle in a side of a planetary carrier;
a bearing seat area for receiving a planetary bearing; and
a link area disposed between the clamping area and the bearing seat area,
wherein the planetary axle is embodied analogously to a transverse link axle and defines a central axis, said link area including at least one through opening which extends at a right angle to the central axis, and at least two transverse link arms which connect the clamping area and the bearing seat area.

### Claim 2

A planetary axle for a planetary gearbox for use in the automotive industry, said planetary axle comprising:
a clamping area for clamping of the planetary axle in a side of a planetary carrier;
a bearing seat area for receiving a planetary bearing; and
a link area disposed between the clamping area and the bearing seat area,
wherein the planetary axle is embodied analogously to a longitudinal link axle, said link area defining a centroidal axis which extends eccentrically with respect to a centroidal axis of the bearing seat area and/or to a centroidal axis of the clamping area.

### Claim 3

A planetary gearbox stage, comprising a planetary axle for use in the automotive industry, said planetary axle comprising a clamping area for clamping of the planetary axle in a side of a planetary carrier, a bearing seat area for receiving a planetary bearing, and a link area disposed between the clamping area and the bearing seat area, wherein the planetary axle is embodied analogously to a transverse link axle and defines a central axis, said link area including at least one through opening which extends at a right angle to the central axis, and at least two transverse link arms which connect the clamping area and the bearing seat area.

### Claim 4 (depends on 3)

The planetary gearbox stage of claim 3, wherein the through opening is aligned at a right angle to a circular path of the planetary axle.

### Claim 5

A planetary gearbox stage, comprising a planetary axle for use in the automotive industry, said planetary axle comprising a clamping area for clamping of the planetary axle in a side of a planetary carrier, a bearing seat area for receiving a planetary bearing, and a link area disposed between the clamping area and the bearing seat area, wherein the planetary axle is embodied analogously to a longitudinal link axle, said link area defining a centroidal axis which extends eccentrically with respect to a centroidal axis of the bearing seat area and/or to a centroidal axis of the clamping area.

### Claim 6 (depends on 5)

The planetary gearbox stage of claim 5, wherein the centroidal axis of the link area is embodied eccentrically with respect to a central axis of the planetary axle and spans together with the central axis a plane of random alignment.

### Claim 7 (depends on 6)

The planetary gearbox stage of claim 6, wherein the plane is aligned tangentially or at a right angle with respect to a circular path of a planet.
