Abstract
A pivotal boat drive having a transmission unit (1) which is driven by a drive engine via a connection point (A). The connection point has an input shaft (11) of a drive device (10) that is rotatably positioned around a first rotational axis (5) and an output shaft (3) that is coupled with the input shaft (11) and rotatable around a second rotational axis (6). The rotational axes (5, 6) are neither parallel nor concentrically positioned with respect to one another. At least one additional connection point (B, C) is provided at the transmission unit (1), at which an additional drive device (20), driven by an additional drive engine, can be positioned to drive the output shaft (3).
Claims11
A pivotable boat drive comprising:
- a transmission unit (1) having an input shaft (11) at a first connection point (A), and the input shaft (11) of a first drive device (10) being positioned, rotatable around a first rotational axis (5), and being drivable by a drive engine;
- an output shaft (3) being coupled with the input shaft (11) and rotatable around a second rotational axis (6);
- the first and the second rotational axes (5, 6) are neither parallel nor concentrically positioned with respect to one another;
- the transmission unit (1) having second and third additional connection points (B, C) so that two additional drive devices (20), each driveable by an additional drive engine, can provide drive to the output shaft (3) of the transmission unit (1);
- and
- the transmission unit (1) thus having three different installation connection points (A, B, C) at which different drives can provide drive to the output shaft (3), the boat drive being pivotable about a pivot axis.
A transmission unit (1) of a pivotable boat drive, the transmission unit (1) comprising:
- a first connection point (A) for connecting a drive motor to the transmission unit (1), the first connection point (A) comprising a drive device (10) with an input shaft (11) that is that is supported adjacent the first connection point (A) by a bearing for rotation about a first rotational axis (5);
- the input shaft (11) being rotationally fixed to a first bevel gear (13);
- a second connection point (B) for connecting an additional drive motor to the transmission unit (1), the second connection point (B) comprising a drive device (20) with a hollow shaft (21) that is rotatably supported at the second connection point (B) by a bearing for rotation about a second rotational axis (6);
- the hollow shaft (21) being rotationally fixed to a second bevel gear (23), the hollow shaft (21) being drivable by the additional drive motor;
- an output shaft (3) being coaxially supported within and rotationally fixed to the hollow shaft (21);
- the first bevel gear (13) engaging the second bevel gear (23) for transmitting drive from the input shaft (11) to the output shaft (3);
- and
- a third connection point (C) for connecting a further drive motor to the transmission unit (1), the third connection point (C) comprising a drive device (30) that is axially aligned along the first rotational axis (5), and the first rotational axis (5) is neither parallel to nor concentrically aligned with the second rotational axis (6).
