Research on heavy truck's unsymmetrical equalizing type of suspension

This paper increase adhesive power of tire by enhancing load on drive axle,and improve the climbing capacity of entire truck.In this paper we proof the reliability of suspension's key parts of the heavy truck that the distance's ratio of drive axle's center and equalizing type of suspension's center with rear axle's center and equalizing type of suspension's center is 4:6.And we produce a heavy truck provide the kind of equalizing type of suspension by this principle.We verify the trial vehicle's dynamical capability is improved than the double rear axle and one drive axle heavy truck with symmetrical equalizing type of suspension by the climbing trial.
