There are generally two types of steering load-bearing axles on the current market: a steering axle actively deflects wheels at an angle using mechanical force. Another is that as the vehicle moves forward, the resistance of the tires will cause the axle to steer or "self-steer" automatically in response to the vehicle turning. For the self-steering bearing axle, when the advancing direction is changed into the opposite direction, the steering function of the self-steering axle needs to be locked, and the direction of the tire needs to be automatically corrected, however, when the self-steering bearing axle runs in the opposite direction, the steering of the tire can not be adjusted in response to the turning of the vehicle, the steering resistance of the vehicle is increased inevitably, the service life of the tire is shortened, and a certain damage effect is caused to the running road surface and the self vehicle body.
Because the existing self-steering bearing axle in the market and the steering vertical shaft are positioned at the front end position of the central axis of the self-steering bearing beam, the structure must generate torque with radial destructive effect, and further the capacity of bearing weight of the existing self-steering axle in the market is limited.
