A first gear drive includes a first one-way clutch engaging the input shaft with the first intermediate shaft and allowing the first intermediate shaft to overrun. A second gear drive includes a jaw clutch for engaging the input shaft with the second intermediate shaft, and also includes a second one-way clutch engaging the second intermediate shaft with the input shaft and allowing the input shaft to overrun. A third gear drive includes another jaw clutch for engaging the first intermediate shaft with the output shaft, and also includes a third one-way clutch engaging the output shaft with the first intermediate shaft and allowing the first intermediate shaft to overrun. A fourth gear drive includes a fourth one-way clutch engaging the second intermediate shaft with the output shaft and allowing the output shaft to overrun. |
