The invention discloses a double-trailing-arm type electric control suspension chassis and a control method thereof, and belongs to the field of electric control suspensions. The chassis comprises a frame, an electric driving wheel and a double trailing arm assembly, the electric driving wheel is connected to the frame through the double trailing arm assembly, and the double trailing arm assemblycomprises a knuckle arm, an upper trailing arm, a lower trailing arm, a torsion bar support frame, an upper torsion bar, a lower torsion bar, a support frame, a lower torsion bar synchronous pulley, an upper torsion bar synchronous pulley and a synchronous belt. The fixing angle of the torsion bar, the rigidity of the suspension and the height of the vehicle body are changed through a suspension adjusting motor so as to meet the requirements for smoothness and operation stability under various working conditions, all the suspensions are controlled in real time through cooperation of the electric control system so as to ensure that the vehicle body is stable, simpler and more scientific, and the current design requirements are met.

    本发明公开了一种双纵臂式电控悬架底盘及其控制方法,属于电控悬架领域,包括:车架、电动行驶轮和双纵臂总成,所述电动行驶轮通过双纵臂总成连接在所述车架上,所述双纵臂总成包括:转向节臂、上纵臂、下纵臂、扭杆支撑架、上扭杆、下扭杆、支撑架、下扭杆同步带轮、上扭杆同步带轮和同步带。本发明通过悬架调整电机改变扭杆的固定角度,改变悬架的刚度以及车身高度,以适应各种工况下平顺性及操纵稳定性的要求,通过电控系统的配合,对各个悬架进行实时控制,以保证车身的平稳,更加简单科学,符合现在设计要求。
