Wheel, first bearing, second bearing, the first lead screw shaft, the first feed screw nut, 5th bearing and 6th bearing are coaxially connected, described
Second screw gear, 3rd bearing, fourth bearing, the second lead screw shaft, the second feed screw nut, 7th bearing and 8th bearing are coaxial
Connection.
6. a kind of appearance according to claim 1 blocks differential type dual-redundancy steering engine, which is characterized in that by changing output shaft
With the structure size for being coupled form and output shaft of mounting base, the dual-redundancy steering engine can be used as dual-redundancy actuator, this
When, output shaft substitutes rudderpost, and the remaining yaw motion of rudderpost becomes the redundancy linear-motion of output shaft.
