The invention discloses a multi-connecting-rod rear suspension system, a chassis and a vehicle, and relates to the technical field of vehicles. The multi-link rear suspension system includes: an auxiliary frame; the steering knuckle is configured to be connected with a wheel; the rear wheel steering gear is connected with the auxiliary frame and is arranged close to the suspension main pin; the two ends of the upper control arm assembly are connected with the steering knuckle and the auxiliary frame respectively; the two ends of the lower control arm assembly are connected with the steering knuckle and the auxiliary frame respectively; the two ends of the toe-in control arm are connected with the steering knuckle and the output end of the rear wheel steering gear respectively; the lower end of the air spring is connected with the lower control arm assembly, the upper end of the air spring can be connected with a vehicle body, and the air spring is connected close to the steering knuckle; the lower end of the shock absorber is connected with the steering knuckle, the upper end of the shock absorber is configured to be connected with a vehicle body, and the shock absorber and the air spring are independently arranged. The large wheel turning angle can be achieved under the same stroke of the rear wheel steering gear, and the turning diameter of the whole vehicle is reduced.
本发明公开一种多连杆后悬架系统、底盘及车辆,涉及车辆技术领域;多连杆后悬架系统包括:副车架;转向节,被配置为能与车轮连接;后轮转向器,与副车架连接,并靠近悬架主销设置;上控制臂组件,其两端分别与转向节和副车架连接;下控制臂组件,其两端分别与转向节和副车架连接;前束控制臂,其两端分别与转向节和后轮转向器的输出端连接;空气弹簧,其下端与下控制臂组件连接,其上端被配置为能与车身连接,空气弹簧靠近转向节连接;减振器,其下端与转向节连接,其上端被配置为能与车身连接,减振器与空气弹簧分别独立设置。本发明可以在后轮转向器的相同行程下实现更大的车轮转角,减少整车的转弯直径。
