Abstract:To improve the tire performance of puncture-proof, explosion prevention and safety, a new mechanical elastic wheel used for offroad vehicle was proposed with main innovation of nonpneumatic elastic structure in wheel. The structure and the working principle of new mechanical elastic wheel were analyzed in detail. According to the loading experiment under wheels driving and braking work conditions, the results show that the moving relationship of each component in the wheel is basically the same with working principle. Under the driving and braking work conditions of new mechanical elastic wheels, the mechanical analyses of inner-wheel and outer-wheel were respectively conducted to obtain the mechanical transmission relationship of internal structure in wheel. The mechanical transmission dynamic simulation under driving and braking work conditions was conducted by ADAMS software, and the simulation results were also analyzed. The results show that the new wheel has effective mechanical transmission characteristics to ensure normal driving of car.
