摘　　要：为了提高轮胎的防刺破、防爆胎及其安全性能,提出一种用于某型越野车的新型机械弹性车轮,其主要创新点在于车轮的无充气弹性结构.深入分析了车轮的系统构成及工作原理,通过对车轮驱动与制动2种工况下进行的装车试验,得出车轮结构中各部件的变形关系与其工作原理基本一致.在驱动与制动2种工况下,分别对新型机械弹性车轮内轮和外轮进行了力学分析,得出车轮内部结构的力学传递关系.最后通过ADAMS软件分别对车轮在驱动与制动2种工况下进行力学传递特性动态仿真,并对仿真结果进行了分析,验证了该新型车轮能够有效地进行力的传递,保证了汽车的正常行驶.To improve the tire performance of puncture-proof, explosion prevention and safety, a new mechanical elastic wheel used for off-road vehicle was proposed with main innovation of non-pneumatic e- lastic 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 condi- tions, 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 me- chanical 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 simu- lation results were also analyzed. The results show that the new wheel has effective mechanical transmis- sion characteristics to ensure normal driving of car.
