A driving simulator steering device with rack limit and displacement measurement, which includes a steering wheel, a rotating shaft, first and second bearings, bearing sleeves, bearing sleeve fixing plates, first, second, and third gears, steering Device frame front plate, bottom plate, left side plate, right side plate, rack, sensor connector, motor, displacement sensor. The front plate, bottom plate, left side plate, and right side plate of the steering gear frame are used to form the main body of the steering gear frame, and the bearing sleeve, the bearing sleeve fixing plate and the first and second bearings are used to install the rotating shaft, and the rotating shaft is sequentially fitted with The steering wheel, the first gear, and the third gear are connected. The second gear is installed on the front shaft end of the motor and meshes with the first gear. The rack is arranged under the third gear and meshes with the third gear. One end of the rack is connected through a sensor. Connect the displacement sensor. The third gear and the rack realize the limit, the motor realizes vibration and return to alignment, and the displacement sensor is used for angle measurement.
