摘要： A two speed transmission includes an input shaft; a lay shaft spaced from the input shaft; a first gear train connecting the input shaft to the lay shaft; a second gear train connecting the lay shaft to an output shaft the gear train including a one way clutch or similar; and a clutch for engaging the input shaft with the output shaft. The transmission is arranged such that when the output shaft is disengaged from the input shaft power is transmitted to the output shaft via the first and second gear trains and the lay shaft. When the clutch is disengaged, power is transmitted from the input shaft via the gear trains and the lay shaft via the one way clutch to the output shaft which typically provides first or low gear for use in low speed maneuvering or where greater torque is required. With the clutch engaged, power may be transmitted from the input shaft directly to the output shaft to provide a second gear for when the watercraft is cruising. This transmission system has the advantage of being extremely compact and since, it requires only a single clutch, provides reduced drag compared with transmission systems incorporating more than one clutch. Advantageously, the default for the transmission has the one way clutch or similar in the first or lower gear, with the clutch normally on, so that if the system fails, it is always possible for the boat owner to get the boat home albeit at a slower speed.
摘要翻译：双速变速器包括输入轴; 与输入轴间隔开的副轴; 将输入轴连接到副轴的第一齿轮系; 将所述副轴连接到输出轴的第二齿轮系，所述齿轮系包括单向离合器或类似物; 以及用于将输入轴与输出轴接合的离合器。变速器布置成使得当输出轴与输入轴分离时，动力经由第一和第二齿轮系和副轴传递到输出轴。当离合器分离时，动力通过单向离合器经由齿轮系和副轴从输入轴传递到输出轴，输出轴通常提供用于低速操纵的第一或低档，或者需要更大的扭矩。随着离合器接合，动力可以从输入轴直接传递到输出轴，以便在船只巡航时提供第二档。该传动系统具有非常紧凑的优点，并且由于与仅包含多个离合器的传动系统相比，仅需要单个离合器就可以减少阻力。有利的是，传动装置的默认值在第一或下部齿轮中具有单向离合器或类似装置，其中离合器通常处于接通状态，使得如果系统失效，则船主总是可以将船返回到原地速度较慢
