Abstract

A generator unit for tractors (1) has a housing (4), which can be non-rotationally mounted on a component of the tractor (1). An input shaft is rotationally supported in the housing (4) and connectable to a power take-off shaft (2) of the tractor (1). An electrical generator (6) is coupled with the housing. The electrical generator (6) has a stator and a rotor, which is drive-wise connected to the input shaft and is driven by the same. The electrical generator (6) serves to driver electrical loads of the tractor 1 or of an agricultural device.

Claims

1. A generator unit for tractors comprising:

a housing non-rotationally being connectable to a component of a tractor;

an input shaft being rotationally supported in the housing, said input shaft connectable to a power take-off shaft of the tractor;

an electrical generator including a stator and a rotor, said rotor is drive-wise connected to and driven by the input shaft, said electrical generator coupled with the housing; and

the electrical generator driving electrical loads of the tractor or of an agricultural device;

an output shaft being drive-wise connected to the input shaft and connectable to the drive shaft of an agricultural device.

2. The generator according to claim 1, wherein the input shaft and the output shaft are formed as a unified component.

3. The generator according to claim 1, wherein the output shaft has an end which can be connected to an agricultural device, which has a profile same as the power take-off shaft of the tractor.

4. The generator unit according to claim 1, wherein a gear is provided between the input shaft and the rotor of the electrical generator.
