The structure and force of steering mechanism in walking tractor is analyzed and studied,the solution for heavy steering in large-power walking tractor is proposed,the four forces compositing the steering force are respectively calculated.

The "discount adhesion coefficient"which is taken to describe the driving force on the driving wheels is proposed,and the conditions of the automobiles with driving steering wheels for good steering capability are analysed as the automobiles are travelling or applying the brakes on smooth and direct or curved road.
