To eliminate abnormity wear of tires in double-front-axle system of heavy truck, the kinematics and dynamics analysis method is set forth. On the base of the results for heavy double-front-axle truck load distributing and manipulate stability, tire uniformity load condition and deficiency steering characteristic condition of heavy double-front-axle truck are put forward. Steering trapezia space movement formula, double-swing-arm space movement formula and double-swing-arm movement formula in actual status of heavy double-front-axle truck are fetched. Optimization models of steering trapezia and double-swing-arm are founded and optimization arithmetics of transmission system in double-front-axle steering are compiled.
