Abstract

A generator unit is provided for attachment to an agricultural work vehicle with a gear module and a generator module. The gear for the driving of the generator module is connected in a drive system with the generator module, and the gear module and the generator module are hydraulically connected with one another via an integrated cooling and lubricating agent circuit.

First claim

The invention claimed is:

1. A generator unit for attachment to an agricultural work vehicle, comprising:
a generator module coupled to a gear module, the generator module and gear module configured to be removably actively coupled to a PTO shaft of the work vehicle at a first coupler location;
an electric power consumer removably passively coupled to the work vehicle at a second coupler location and connected to the generator module; and
a power electronics system operably controlling an operation of the generator module and the electric power consumer.

2. The generator unit of claim 1 , further comprising a cooling circuit for cooling the power electronics system.

3. The generator unit of claim 2 , wherein the cooling circuit comprises a water circuit.

4. The generator unit of claim 2 , wherein the cooling circuit comprises an oil circuit.

5. The generator unit of claim 4 , further comprising an integrated cooling and lubricating agent circuit wherein the integrated cooling and lubricating agent circuit of the generator module, the gear module, and the cooling circuit of the power electronics system comprise one circuit.

6. The generator unit of claim 1 , wherein at least one interface for the delivery of an alternating voltage and at least one interface for the delivery of a direct voltage are provided to the electric power consumer.

7. A work vehicle system, comprising:
a work vehicle having a PTO and a first coupler location and a second coupler location;
an electric power consumer removably passively coupled to the work vehicle at the first coupling location; and
a generator unit having a power electronics system, the generator unit being removably passively coupled to the work vehicle at the second coupling location;
wherein, the generator unit is removably actively coupled to the PTO to provide power to the power electronics system;
further wherein, the power electronics system selectively controls the electric consumer.

8. The work vehicle system of claim 7 , further wherein the generator unit further comprises a frame that is removably coupled to the agricultural work vehicle via a three-point suspension.

9. The work vehicle system of claim 8 , further wherein the generator unit further comprises a generator module coupled to the frame.

10. The work vehicle system of claim 8 , further wherein a ballast weight is removably coupled to the frame.

11. The work vehicle system of claim 7 , further wherein the electric power consumer is removably electrically coupled to the generator module with a pluggable interface and an electric conductor.

12. The work vehicle system of claim 7 , further herein, the electric consumer is an electric motor that drives an axle of an attached device.

13. The work vehicle system of claim 7 , further wherein the power electronics system has both high voltage and control cable connections coupled thereto.

14. The work vehicle system of claim 7 , further wherein the generator unit further comprises an integrated cooling and lubricating agent circuit having a first heat exchanger.

15. The work vehicle system of claim 14 , further comprising a second heat exchanger, wherein the first heat exchanger is fluidly coupled to a generator module and a gear module and the second heat exchanger is fluidly coupled to the power electronics system.
