The invention relates to a four-wheel independent steering robot chassis which comprises a frame, a driving mechanism, a suspension mechanism, a steering mechanism and a control mechanism, wherein thedriving mechanism, the suspension mechanism, the steering mechanism and the control mechanism are all connected to the frame, and the steering mechanism and the driving mechanism are both connected with the suspension mechanism; the suspension mechanism comprises a lower suspension, an upper suspension, a steering knuckle, a plurality of knuckle bearings, a lower suspension shaft, a shock absorber shaft, an upper suspension shaft and a shock absorber; the lower suspension and the upper suspension are connected to the frame; the lower suspension shaft and the shock absorber shaft are connectedto the lower suspension; the upper suspension shaft is connected to the upper suspension; and the lower end of the shock absorber is connected with the shock absorber shaft. According to the four-wheel independent steering robot chassis, independent driving, independent steering and independent suspension of the four wheels are achieved, the robot chassis can rotate in situ, multiple operation modes such as front wheel steering and rear wheel driving and four-wheel steering and four-wheel driving are achieved, and the robot chassis is compact in structure, free in movement mode, high in movement speed, stable in movement and high in obstacle avoidance capacity.

    本发明涉及一种四轮独立转向的机器人底盘,包括车架、驱动机构、悬挂机构、转向机构以及控制机构,所述驱动机构、悬挂机构、转向机构和控制机构均连接在车架上,所述转向机构和驱动机构均与悬挂机构连接;所述悬挂机构包括连接在车架上的下悬架和上悬架、转向节、若干个关节轴承、连接在下悬架上的下悬架轴和减震器轴、连接在上悬架上的上悬架轴以及减震器,所述减震器的下端与减震器轴连接。该四轮独立转向的机器人底盘,四轮实现独立驱动、独立转向和独立悬挂,使得机器人底盘能原地旋转,具有前轮转向后轮驱动、四轮转向四轮驱动等多种运行方式,机器人底盘结构紧凑,运动方式自由,移动速度快,运动平稳,避障能力强。
