The invention discloses a suspension system of an electric vehicle platform, a chassis system and a vehicle, the suspension system comprises a first beam body, a first connecting piece and a second connecting piece, and the first connecting piece can rotate at the two ends of the first connecting piece around the axis extending in the length direction of a vehicle frame; the second connecting piece can rotate on the first connecting piece around the axis extending in the width direction of the vehicle frame, the number of unsprung components is reduced, abnormal sound is reduced, the NVH performance is improved, the overall structure reduces occupied arrangement space, disassembly and assembly operation is facilitated, meanwhile, the arrangement space of a chassis battery is increased in a disguised mode, the endurance mileage of the vehicle is increased, and the service life of the vehicle is prolonged. In the complex form working condition, the first connecting piece is connected with the vehicle frame through the first beam body and the second connecting piece, through relative motion compensation formed by the first connecting piece, the difficulty of adaptive control over the wheels arranged on the first connecting piece is lowered, the flexibility and stability of the vehicle are improved, and changes of the camber angle and the toe-in angle of the wheels are reduced; the dynamic stability is improved.

    本发明公开了一种电动车平台的悬架系统、底盘系统及车辆,悬架系统包括第一梁体、第一连接件以及第二连接件,第一连接件可绕以车架长度方向延伸的轴线在第一连接件两端转动,第二连接件可绕以车架宽度方向延伸的轴线在第一连接件上转动,减少簧下部件数量,减少异响,提升NVH性能,而且整体结构降低对布置空间的占据,便于拆装作业的同时,还变相增加底盘电池的布置空间,增加车辆续航里程,在复杂的形式工况中,第一连接件分别通过第一梁体、第二连接件与车架连接,并通过第一连接件所形成的相对运动补偿,降低对装设在第一连接件上车轮适应性控制的难度,提高车辆灵活性和稳定性,降低车轮外倾角及前束角的变化,提高动态稳定性。
