Abstract
A self-propelled work machine, in particular a mobile crane, comprises an undercarriage configured for moving the work machine, a superstructure which is rotatably mounted on the undercarriage, and a drive device comprising a drive motor. The drive device comprises a moment transmission which is formed between the superstructure and the undercarriage and configured to transmit power outputted by the drive motor between the superstructure and the undercarriage in the form of a moment. At least one and, in particular, all of the elements to be driven receive a moment about an axis which extends in the region of a rotary bearing of the superstructure and the undercarriage, in particular about the rotational axis of the superstructure.

A self-propelled work machine, comprising an undercarriage configured for moving the work machine, a superstructure which is rotatably mounted on the undercarriage, and a drive device comprising a drive motor, wherein the drive device comprises a moment transmission which is formed between the superstructure and the undercarriage and configured to transmit power outputted by the drive motor between the superstructure and the undercarriage in the form of a moment, wherein at least one element to be driven receives a moment about an axis which extends in a region of a rotary bearing of the superstructure and the undercarriage characterised in that the moment transmission comprises a shaft which extends between the superstructure and the undercarriage and does not extend parallel to a rotational axis of the superstructure.
A self-propelled work machine comprising:
- an undercarriage configured for moving the work machine;
- a superstructure rotatably mounted to the undercarriage, the superstructure configured to rotate about a rotational axis;
- a rotary bearing connected to the undercarriage and the superstructure;
- a drive device that includes:
- a drive motor that outputs power;
- a moment transmission positioned between the superstructure and the undercarriage and configured to transmit the power in the form of a moment between the superstructure and the undercarriage, wherein the moment transmission comprises a shaft which extends between the superstructure and the undercarriage and does not extend parallel to the rotational axis of the superstructure;
- and
- a pump configured to receive the moment about an axis that extends about the rotational axis of the superstructure.
