## Abstract

A support structure of a wind turbine and a method of manufacturing the support structure is provided. A support structure of a wind turbine is disclosed, whereby the support structure includes a first end to connect to a rotor of a wind turbine, and a second end to be connected to a tower of a wind turbine. The support structure includes an intermediate part that connects the first end to the second end, and that the intermediate part includes the form of an elbow-shaped tube. The support structure is divided into at least two segments whereby the segments are transportable individually from a manufacturing site to a construction site. The segments are connectable in a way that the support structure is capable of transferring forces from the rotor to the tower.

## Claims

### Claim 1

A support structure of a wind turbine comprising:
a first segment having an end that defines a first end of the support structure, the end of the first segment configured to connect to a rotor of the wind turbine;
a second segment defining a second end of the support structure, the end of the second segment configured to connect a tower of the wind turbine; and
an intermediate part that connects the first segment to the second segment, the intermediate part including a form of an elbow-shaped tube;
wherein the intermediate part is divided into two segments, the two segments being transportable individually from a manufacturing site to a construction site, and connectable in a way that the support structure is capable of transferring forces from the rotor to the tower.

### Claim 2 (depends on 1)

The support structure according to claim 1, wherein the first segment comprises at least two parts that are configured to connect to the rotor and to the second segment.

### Claim 3 (depends on 1)

The support structure according to claim 1, wherein the first segment, the second segment or the intermediate part of the support structure is made of casted material.

### Claim 4 (depends on 1)

The support structure according to claim 1, wherein the support structure is prepared and arranged in a way to connect a generator of a direct driven wind turbine to the support structure.

### Claim 5 (depends on 4)

The support structure according to claim 4, wherein the first end is prepared and arranged in a way to connect the generator of the direct driven wind turbine to the support structure.
