摘要

A suction excavator pump transmission (2) of a suction excavator (1), with a driveshaft (5), to which a drive motor (4) can be coupled, with an output shaft (6) to which a pump impeller of a 5 suction excavator pump (3) can be coupled, wherein on the driveshaft (5) drive-side gearwheels (7, 8) are rotatably mounted, wherein on the output shaft (8) output-side gearwheels (9, 10) are mounted in a rotationally fixed manner, and wherein a clutch (13, 14) interacts in each case with each drive-side gearwheel (7, 8) in such a manner that in particular when the respective clutch (13, 14) is closed, the respective drive-side gearwheel (7, 8) is coupled to the driveshaft (5) in a 10 rotationally fixed manner, Whereas in particular when the respective clutch (13, 14) is opened, the respective drive-side gearwheel (7, 8) is freely rotatable (1)relative to the driveshaft (5).
