The invention discloses a novel steering mechanism capable of realizing partial steer-by-wire function. The novel steering mechanism comprises a
steering wheel, an electromagnetic contracting
brake, asun gear, a plurality of planetary gears, a gear ring, a planetary carrier, a worm and a decoupling driving mechanism, wherein the
steering wheel is fixedly connected with a
steering column; the electromagnetic contracting
brake is coaxially and fixedly connected with the
steering column; the sun gear is coaxially and fixedly connected with the electromagnetic contracting
brake; the planetary gears are circumferentially and uniformly arranged on the outer side of the sun gear and are in meshed transmission with the sun gear; the gear ring is arranged concentric with the sun gear, the inner ring is in meshed transmission with the planetary gears, and the outer ring is provided with worm gear teeth; the planetary carrier is rotationally connected with gear shafts of the planetary gears in the circumferential direction, and a tubular
column structure vertically extends from the center of one side, away from the
steering wheel, of the planetary carrier and is used for being connected witha steering gear; the worm is in meshed transmission with the worm gear teeth of the outer ring of the gear ring; and the decoupling driving mechanism is connected with the worm and is used for driving the worm to rotate. A control method of the novel steering mechanism capable of realizing the partial steer-by-wire function is further provided.
