Design and Obstacle Crossing Performance Analysis of a New Type Wheeled Walking Self-adjusting Chassis

For the turbulence problems of mountain or uneven ground transport vehicle, the traditional rigid chassis does not adapt to the development of new engineering transport vehicles. For solving this problem, a new type of wheeled walking self-adjusting mobile chassis is designed for power transmission and transportation engineering in this paper. A new double wishbone independent suspension structure is designed as the chassis to achieve support and obtain the balance. The overall structure of the chassis is introduced and the motion model of the chassis is also constructed to explain work principle. Additionally, the principle of bottom plate drive and steering motion are analyzed. In addition, the obstacle crossing ability of the mobile chassis is also analyzed, and the walking stability of the chassis during obstacle crossing is studied. The results show that the mobile chassis can maintain a stable motion posture during obstacle crossing and has good road adaptive ability and obstacle crossing performance.
