Abstract
The invention discloses an initiative guiding method and an initiative guiding device of a railway vehicle wheel pair, and relates to the steering technique of a railway vehicle. An independent wheel pair is fixedly arranged at one end of an axle; two left and right sets of planetary gear trains are respectively arranged on the inner side of the axle; a sun gear of each planetary gear train is fixed together with the axle of the independent wheel pair; a planet wheel of each planetary gear train is fixed together with a planet carrier through a bearing on a planet axle; the planet carrier is linked with the axle through the sun gear meshed with the planet wheel; the end face is fixed together with a shell through a connecting shaft and a bearing; external gear rings meshed with driving gears fixed at the two ends of a transmission shaft are arranged on the external circle of the planet carrier; two left and right sets of planetary gear trains are linked on the inner side of the independent wheel pair through the transmission shaft; an internal gear ring of a differential gear train on the left side is linked with the shell through the bearing; a worm gear-worm rod pair is arranged on the external gear ring, and is linked with a differential motor through a speed reducer; the internal gear ring of an ordinary gear train on the right side is fixed together with the shell. The initiative guiding method provided by the invention is mainly used for manufacturing a bogie of the railway vehicle.
