Abstract:
1. A rotational power transmission apparatus comprising: a first input shaft; a differential engine coupled to the first input shaft, a first one-way bearing coupled to the first output shaft; a first torque converter coupled to the first one-way bearing, the first one-way bearing transmitting power, between the first output shaft and the first torque converter, when the first one-way bearing is driven by the first output shaft rotating in a first direction or when the first output shaft is driven by the first one-way bearing to rotate in a second direction opposite the first direction; a second one-way bearing coupled to the first output shaft; a second torque converter coupled to the second one-way bearing, the second one-way bearing transmitting power, between the first output shaft and the second torque converter, when the first one-way bearing is driven by the first output shaft rotating in the second direction or when the first output shaft is driven by the first one-way bearing to rotate in the first direction; and a first output coupler coupled to output from the first torque converter, output from the second torque converter and a second output shaft.
