| Abstract: | The analysis method of automobile dynamics is used to analyze the relation between the wheelbase of the heavy-duty automobile with the double front axle and the load of the tires.The differential equation of planar motion of the automobile is established.The expressions of the steady state yaw rate gain and the stability factor are given.Also presented are the condition under which the average load of the tires can be achieved and the condition under which the whole vehicle has the performance of deficient turning.An application example is shown.The results provide a theoretical basis for the reasonable design of the wheelbase of heavy-duty automobiles with the double front axle. |
| Keywords: | heavy-duty automobile with the double front axle wheelbase deficient turning |
