The invention belongs to the technical field of unmanned driving, and relates to a drive-by-wire chassis system of a four-wheel independent steering unmanned vehicle, which comprises a vehicle body framework, a plurality of suspension systems and a plurality of steering systems arranged below the vehicle body framework, and each suspension system corresponds to one steering system. Each suspensionsystem comprises a linear bearing mechanism, a rotary damping mechanism and a spring buffer mechanism, the two ends of each rotary damping mechanism are fixed to the vehicle body framework and the steering system respectively, and the upper end and the lower end of the spring buffer mechanism are elastically connected to the upper end of the linear bearing mechanism and the top of the steering system respectively. Movement of the steering system can be restrained through the linear bearing mechanism, so that the steering system only moves in the vertical direction, the anti-rotation effect onwheels in the damping process is achieved, and the buffer spring and the rotary damping mechanism work at the same time so as to effectively absorb energy generated by shaking of the vehicle.

    本发明的一种四轮独立转向无人驾驶车辆的线控底盘系统,属于无人驾驶技术领域,包括车身骨架,还包括多个悬架系统和多个设置在车身骨架下方的转向系统,每个所述悬架系统均对应一个转向系统,悬架系统包括线性轴承机构、旋转阻尼机构和弹簧缓冲机构,旋转阻尼机构的两端分别固定于车身骨架和转向系统上,弹簧缓冲机构的上下两端分别弹性连接于线性轴承机构的上端和转向系统的顶部。本发明通过线性轴承机构能够对转向系统的移动进行约束,使转向系统仅在上下方向进行移动,来实现对车轮在减震过程中的防转作用,并且本发明通过缓冲弹簧以及旋转阻尼机构同时工作,以有效吸收车辆抖动产生的能量作用。
