The invention discloses a disconnected type steer-by-wire mechanism which comprises a steering wheel and a shell, a motor is fixedly installed on the shell, the output end of the motor is located in the shell, an output shaft of the motor is connected with a transmission mechanism, and the transmission mechanism can drive wheels to steer; the transmission mechanism comprises a worm and a ball screw, the worm is in key connection with an output shaft of the motor, a lead screw seat of the ball screw is fixedly sleeved with a gear ring meshed with the worm, the lead screw seat of the ball screw is fixedly sleeved with two bearings, the two bearings are located on the two sides of the gear ring respectively, and the two bearings are connected with the gear ring in a sleeved mode. And the bearing is arranged in the shell. According to the invention, 100% Ackerman rate can be realized at any turning angle, the tire is in pure rolling and has no sideslip during steering, the tire wear is greatly reduced, and the spatial arrangement of the steering mechanism can be effectively optimized.
