The rubber track chassis comprises wheels and tracks, wherein the wheels are provided with wheel axles, the wheels are covered with anti pulleys, and the anti pulleys are fixedly connected to the wheels through locking buckles. The locking buckles are provided with several and evenly distributed on the inner ring of the anti pulleys, and the outer ring of the anti pulleys is provided with gear teeth; The outer side of the wheel is equipped with a triangular support frame composed of telescopic rods, and at each of the three vertices of the triangular support frame, there is a driven wheel shaft arranged parallel to the wheel axis. Each driven wheel shaft is hinged with a driven wheel. The present invention utilizes the driven wheels hinged at the three vertices of the triangular support frame to enable the wheel to have better walking ability when encountering uneven ground; The use of anti slip wheels on the wheels can prevent the vehicle from slipping; Wheeled vehicles can be transformed into tracked vehicles through the use of tracks that cooperate with anti-skid pulleys. This not only surpasses the agility and maneuverability of general tracked vehicles, but also improves the vehicle's ability to pass through
