Abstract
An agricultural working machine, method, and power take-off transmission are provided. The agricultural working machine includes an internal combustion engine, at least one power take-off, and an arrangement for dynamically adjusting at least one of a speed and a torque of the PTO. The arrangement includes an electric machine and a transmission summing the driving force of the internal combustion engine and the electric machine. The transmission includes at least two gear elements that are magnetically coupled.
Claims14
An agricultural working machine with an internal combustion engine and an auxiliary drive, the agricultural working machine comprising:
- at least one power take-off;
- an arrangement for dynamically adjusting at least one of a speed and a torque of the PTO;
- wherein the arrangement comprises an electric machine and a transmission summing the driving force of the internal combustion engine and the electric machine;
- and
- wherein the transmission comprises at least two gear elements that are magnetically coupled.
A method of operating a magnetic transmission with a power take-off transmission, the method comprising:
- dynamically adjusting a speed and a torque of a power take-off shaft in an agricultural machine, wherein the power take-off transmission comprises at least two transmission elements magnetically coupled to each other.
A power take-off transmission for transmitting drive torque to a power take-off, the power take-off transmission comprising:
- an arrangement for dynamically adjusting at least one of a speed and a torque of the power take-off with an electric machine configured to be connected to an electrical network;
- and
- at least three transmission elements, wherein one of the at least three transmission elements is configured to be connected to an input stage and another of the at least three transmission elements is connected to the electric machine such that a third transmission stage sums initiated torque, wherein at least two of the at least three transmission elements are magnetically coupled to each other.
