Zusammenfassung:A gearbox includes a planetary gearset and a first input shaft coupled to a sun gear of the planetary gearset. A second input shaft is coupled to a ring gear of the planetary gearset, and an output shaft is coupled to planet gears of the planetary gearset via a carrier. The gearbox further includes a second coupling path between the first input shaft and the second input shaft that is separate from the planetary gearset. The second coupling path includes a clutch that engages and disengages in response to a speed differential between the first input shaft and the second input shaft
