The bidirectional overrunning clutch can bidirectionally drive the driven end when the driving end of the bidirectional overrunning clutch is used as a driving source, and can be automatically in a separation state when the driven end of the bidirectional overrunning clutch is used as the driving source. It can be understood that, under the condition that the first motor 100 works normally, the first motor 100 as a driving source to drive the first overrunning bidirectional clutch 50 can drive the first gear 41; when the first motor 100 fails, the first motor 100 cannot generate enough power, and if the first gear 41 is driven by the second gear 42 to rotate continuously, the first overrunning bidirectional clutch 50 does not transmit the power of the first gear 41 to the first motor 100 in a reverse direction, but is automatically in a disengaged state when the first gear 41 is used as a driving source, so as to isolate the first motor 100 from a failure. Similarly, under the condition that the second motor 200 works normally, the second motor 200 as a driving source to drive the second overrunning bidirectional clutch 60 can drive the third gear 43; when the second motor 200 fails, the second motor 200 cannot generate enough power, and if the third gear 43 continues to rotate under the driving of the second gear 42, the second overrunning bidirectional clutch 60 does not transmit the power of the third gear 43 to the second motor 200 in the reverse direction, but is automatically in a disengaged state under the condition that the third gear 43 serves as a driving source, so as to isolate the second motor 200 from the failure.

Referring to fig. 1 and 2, an embodiment of the second aspect of the present application provides a steering engine system, which includes a first electric motor 100, a second electric motor 200, a dual-redundancy transmission device provided in an embodiment of the first aspect of the present application, and an output actuator 500.
According to the steering engine system provided by the embodiment of the second aspect of the present application, when the first motor 100 and the second motor 200 both work normally, the power flow output by the first motor 100 and the power flow output by the second motor 200 can be converged to the second gear 42 by using the three-gear mechanism 40, and is transmitted to the output actuator 500 through the transmission shaft of the second gear 42; when the first motor 100 fails, the second motor 200 drives the third gear 43 through the second bidirectional overrunning clutch 60, the third gear 43 is meshed with the second gear 42, the power flow output by the second motor 200 is transmitted to the output execution mechanism 500 through the second gear 42, the second gear 42 is meshed with the first gear 41, the first gear 41 is used as a driving source to drive the first bidirectional overrunning clutch 50 under the driving of the second gear 42, and the first overrunning clutch 50 is automatically in a separation state under the condition that the driven end of the first overrunning clutch 50 is used as the driving source, so that the fault isolation of the first motor 100 is realized; similarly, the second bi-directional overrunning clutch 60 may automatically fault isolate the second motor 200 in the event of a failure of the second motor 200. It can be seen that, with the steering engine system that this application embodiment provided, when arbitrary motor broke down and resulted in unable positive drive rather than the two-way freewheel clutch who is connected, this two-way freewheel clutch was in the disengagement state promptly automatically to carry out fault isolation to this motor, need not the manual work and cut off the power supply to trouble motor etc. and operate, degree of automation is higher and whole transmission reliability is higher.

Therefore, the motors and the output executing mechanism 500 of the steering engine system are connected with the position sensors, so that the steering engine system can be automatically controlled.
