All-terrain vehicle based on four-connecting-rod deformable principle

Abstract

The invention relates to an all-terrain vehicle based on a four-connecting-rod deformable principle, which is an all-terrain vehicle according to a deformable principle. The all-terrain vehicle adopts a modularized design and can adapt to a plurality of terrains. A first module is in a front wheel structure; related mechanical design knowledge is used for designing a four-connecting-rod type front wheel structure; a rack of four connecting rods is mounted on a vehicle body; a front wheel is fixed on connecting rods; and a steering engine is fixed on the connecting rods to control the direction. In order to increase the friction force between the front wheel and the ground, stretched springs are mounted in opposite angle directions of the four connecting rods so that the front wheel is prevented from leaving away from the ground. A second module comprises wheels on two sides of the vehicle body; the two sides of the vehicle body adopt symmetrical structures and adopt four-connecting-rod structures; wheels are fixed on two cranks, and the connecting rods and the rack are fixed on the vehicle body; and meanwhile, the vehicle body can rotate freely. According to the all-terrain vehicle, the front wheel and the wheels on the two sides adopt the four-connecting-rod structures so that the all-terrain vehicle has the characteristics of strong adaptive capacity, high stability, simple and reliable structure, reasonable overall layout, simple and beautiful appearance, prominent movement performance, simple and efficient control and the like.

Description

technical field [0001] The invention belongs to the technical field of all-terrain vehicles, and in particular relates to a structural design and a device capable of realizing all-terrain movement through the deformable principle of four links. Background technique [0002] The crawler or 4-wheel mobility of traditional all-terrain vehicles has been widely used. With the increasing complexity of the environment, the requirements for the adaptability of all-terrain vehicles are constantly increasing, and they can adapt to a variety of complex terrains. To a certain extent, the stability of the vehicle body is guaranteed, and the all-terrain vehicle with unmatched maneuverability by ordinary all-terrain vehicles will have better development prospects. At present, most all-terrain vehicles at home and abroad adopt light crawler type, and the front and rear car bodies are driven by power and linked by hydraulic articulation. And the longitudinal passing radius is smaller than t...
