The invention relates to the technical field of individual tracked vehicles, in particular to a double continuously variable transmission steering mechanism. The steering mechanism comprises a speed reduction box, a left output shaft, a right output shaft and a main transmission shaft, the left output shaft, the right output shaft and the main transmission shaft are arranged in the speed reduction box, the speed reduction box is formed by oppositely combining two shells, the main transmission shaft is in transmission connection with the left output shaft and the right output shaft through two belted continuously variable transmission mechanisms, and the rotation speed ratio of the left output shaft to the right output shaft is 1:4-4:1. In the steering process, the larger left and right displacement of a speed regulation wheel disc is, the larger the width difference of two driving belt wheels is, the larger the steering angle of the left output shaft and the steering angle of the right output shaft are, and therefore the large and small radius cornering control function is achieved. The steering mechanism is suitable for small tracked vehicles under various road condition environments; by means of specific rotation speed differences, steering flexibility of the vehicles can be guaranteed at a low speed, security can also be guaranteed when the vehicles turn a corner at a high speed, side turn caused by overhasty cornering is prevented, safety is high, and practicability is high.
