The invention discloses a double-motor type electric direct-drive steering gear comprising a driving motor I, a planetary roller lead screw, a fan-shaped gear, an output shaft and a driving motor II.An output shaft of the driving motor I is connected with one end of the planetary roller lead screw, the other end of a lead screw of the planetary roller lead screw is connected with an output shaftof the driving motor II, the planetary roller lead screw is connected with the fan-shaped gear in a meshed mode through a gear, and the fan-shaped gear is installed on the output shaft. The working efficiency is high, noise pollution is small, and the phenomena of air leakage and liquid leakage do not exist; on the basis of the double-motor structure, the reliability of the whole system is improved; when a large steering force is needed, the two driving motors can be used at the same time, so that the steering force is increased, and the flexibility of the whole mechanism is enhanced; the complexity of the steering mechanism can be simplified, the boundary dimension can be reduced, and the service life can be prolonged.
