This paper put forward the solution of the wheel side deceleration electric drive system of double trailing arm suspension, through the combination of the trailing arm suspension and the electric drive system of wheel side deceleration. And the geometric mathematical model of the double trailing arm suspension based on the four-bar mechanism was established. MATLAB executable file and the program interface was compiled, which quickly located the motor center layout position under the given conditions. When the wheel jumps, the center distance between the motor and the wheel remains unchanged. According to the reasonable parameters of the trailing arm structure provided by MATLAB, CATIA three-dimensional modeling was carried out, and ADAMS was imported for kinematics simulation, which verified the feasibility of the design scheme of the double trailing arm suspension and the MATLAB program.
