This paper introduces the steering mechanism structure of heavy equipment carrier and 5 steering modes. The wheel shaft must be designed mechanically and independently each other to realize these 5 steering modes, the independent and multi - wheel steering mechanism can use electric driving control mode only. The paper analizes tile requirements and features of electric driving steering system, make an optimized design of driving connecting rod mechanism and achieved a better design result, this can provide...
