The invention discloses a vehicle and a suspension structure thereof, the vehicle comprises a front axle suspension and a rear axle suspension, at least one of the front axle suspension and the rear axle suspension comprises steering suspensions symmetrically arranged on the left side and the right side of a vehicle body, each steering suspension comprises a steering stand column, a steering rod set and an anti-overturning rod set, the connecting part is used for connecting the steering column with a vehicle body to adapt to steering actions of wheels; the anti-overturning rod set is connected to the steering stand column and the vehicle body, comprises a swinging piece, an elastic connecting piece, an offset distance connecting rod and a push-pull rod and is used for driving the vehicle body to incline towards the bent inner side in a self-adaptive mode when the vehicle turns. According to the suspension structure, when the vehicle turns, the height of the mass center of the vehicle body relative to the walking datum plane of the wheels can be reduced, meanwhile, the wheel distance of the wheel on the side away from the turning center of the vehicle body relative to the mass center of the vehicle body can be increased, then the rollover resistance of the suspension structure is improved, and an active rollover resistance suspension such as a rollover resistance electronic system does not need to be added; and the cost and the energy consumption are greatly reduced.
本发明公开了一种车辆及其悬架结构,包括前轴悬架和后轴悬架,前轴悬架和后轴悬架这两者中的至少一者包括对称布置于车体的左右两侧的转向悬架,转向悬架包括转向立柱、转向杆组和抗翻杆组,其中,转转向杆组,用于连接转向立柱与车体,以适配车轮的转向动作;抗翻杆组连接于转向立柱与车体,且包括摆转件、弹性连接件、偏距连杆和推拉杆,用于车辆转弯时以自适应的方式带动车体向弯内侧倾斜。该悬架结构,在车辆转弯时不仅能够降低车体的质心相对车轮的行走基准面的高度,同时能够远离车体转弯中心一侧的车轮相对车体的质心的轮距,继而提升了悬架结构抗侧翻能力,且不需要增加抗侧翻电子系统等主动抗侧翻悬架,大大降低了成本和能耗。
