Abstract

The utility model provides a device for improving the off-road capability of a wheeled vehicle, which comprises a ground stepping device extending along the radial direction of the wheel, wherein the ground stepping device can rotate along with a tire and always faces the ground, the ground stepping device contacts the ground when being in a low position in the rotation process, and a dynamic supporting point is formed and a reaction force is generated in the rotation period of the wheel, so that the wheel is helped to be lifted. The device relies on the natural rotation of the wheels to trigger the ground pedaling action, thereby helping the wheels to lift or span obstacles so as to overcome the road section where the vehicles stagnate due to the skidding and the trapping of the driving wheels, the design can enhance the off-road capability of the traditional wheeled vehicle, is particularly suitable for uneven terrain, skidding positions or the scenes needing climbing, and improves the off-road capability of the wheeled vehicle on viscous, loose, damaged, unpaved and other difficult-to-pass road surfaces. The device is simple to use and easy to install, does not need other special tools, and can be easily operated by even people without technology or expert knowledge.
