Wheel-caterpillar alternative type all-terrain vehicle

Abstract

The invention discloses a wheel-caterpillar alternative type all-terrain vehicle and belongs to the technical field of all-terrain vehicles. The provided wheel-caterpillar alternative type all-terrainvehicle with a high movement speed and a great obstacle crossing capability aims at overcoming defects of all-terrain vehicles of wheel structures and defects of all-terrain vehicles of caterpillar structures. On the basis of the all-terrain vehicles of the caterpillar structures, four lifting wheels are added, lifting movement mechanisms are designed by using connecting rods and driven by stepping motors, ascending and descending of the four lifting wheels can be achieved, and wheel-caterpillar alternative or cooperative work is achieved. When the all-terrain vehicle passes through muddy land and a desert, four triangular caterpillars are driven separately; when the all-terrain vehicle crosses a trench and climbs stairs and steps, the four triangular caterpillars and two rear lifting wheels are driven; the four lifting wheels are driven to run on a flat road separately. The all-terrain vehicle is more suitable for complex and varied terrains and has high practicality.

Description

technical field [0001] The invention belongs to the technical field of all-terrain vehicles. Background technique [0002] Different application fields and application requirements of all-terrain vehicles have considerable differences in their structural forms. Generally, it can be divided into wheeled all-terrain vehicles, footed all-terrain vehicles, and tracked all-terrain vehicles. Compared with wheeled all-terrain vehicles, the footed all-terrain vehicle has the advantage of lower requirements on the terrain, can easily cross obstacles, and walk through special roads such as sand and swamps, but the disadvantage is that the control system is extremely complicated and the development cycle is long. Wheeled all-terrain vehicles have higher movement speed and efficiency, while controlling the drive is relatively simple, and the radius of activity is far more than that of footed all-terrain vehicles. Therefore, it has wider application prospects. In practical application...

Problems solved by technology

However, it is difficult for wheeled all-terrain vehicles to pass through harsh road conditions such as sandy land, tidal flats, ice and snow, etc.

Tracked all-terrain vehicles have good obstacle-crossing performance and strong passability, and can well adapt to harsh road environments such as sandy land, tidal flats, ice and snow that wheeled all-terrain vehicles are not capable of. Its disadvantages are low driving speed and poor maneuverability
