The invention relates to the technical field of robot driving chassis, in particular to a wheel type driving system and a chassis. The wheel type driving system comprises a base body; a roller; the first cantilever is connected to the base body; the mounting seat is rotatably connected to the first cantilever in the horizontal direction, and the roller is mounted on the mounting seat; the first connecting rod comprises a first connecting end and a second connecting end, and the first connecting end is hinged to the mounting base; the steering transmission part is rotatably arranged on the base body in the horizontal direction, and the steering transmission part is hinged to the second connecting end; the driving mechanism is used for driving the steering transmission part to rotate so as to push the mounting seat to rotate through the first connecting rod to steer the roller; and the steering transmission part, the first connecting rod, the mounting seat and the first cantilever form a parallelogram connecting rod mechanism. According to the technical scheme, the mounting base is kept parallel to the steering transmission part, so that the posture of the roller is kept unchanged in the up-down shaking process, the problem of accidental deflection of the roller is solved, and the positioning walking accuracy is improved.
本申请涉及机器人驱动底盘技术领域,具体涉及一种轮式驱动系统及底盘。轮式驱动系统包括:基体;滚轮;第一悬臂,连接于基体;安装座,在水平方向上可转动地连接于第一悬臂,滚轮安装于安装座;第一连杆,包括第一连接端和第二连接端,第一连接端与安装座铰接;转向传动件,在水平方向上可转动地设置于基体,转向传动件与第二连接端铰接;驱动机构,用于驱动转向传动件转动,以通过第一连杆推动安装座转动,使滚轮转向;其中,转向传动件、第一连杆、安装座和第一悬臂构成平行四边形连杆机构。本申请技术方案中,安装座在保持与转向传动件平行,使得滚轮的姿态在上下抖动过程中保持不变,从而消除滚轮意外偏转的问题,提高定位行走精确度。
