The invention relates to the technical field of traffic transportation, and discloses a mobile platform which comprises N chassis and N+1 drive axles, and N is a positive integer larger than or equal to 1. Each drive axle comprises a drive axle support and wheels rotationally connected to the drive axle support, chassis hinge connecting pieces are arranged on the two sides of the chassis respectively, the N chassis and the N+1 drive axles are sequentially arranged at intervals, and the drive axle supports are hinged to the chassis hinge connecting pieces through coaxial hinges or double-shaft hinges. Two ends of each drive axle support are rotationally connected with wheels, the angles of the wheels relative to the drive axle supports are unchanged, and the wheels are provided with wheel driving mechanisms for driving the wheels to rotate. Compared with the prior art, steering is achieved through the differential speed of a left wheel and a right wheel of the vehicle, a complex steering mechanism is omitted, the cost and the weight of the vehicle can be reduced, and meanwhile the vehicle has the expansion capacity.
本发明涉及交通运输技术领域,公开了一种移动平台,包括底盘、驱动桥,底盘个数为N个,驱动桥个数为N+1,N为大于等于1的正整数;驱动桥包括驱动桥支架以及转动连接于驱动桥支架的车轮,底盘两侧分别设置底盘铰链连接件,N个所述底盘与N+1个驱动桥依次间隔设置,且驱动桥支架与底盘铰链连接件通过共轴铰链或双轴铰链铰接;驱动桥支架两端转动连接有车轮,车轮相对所述驱动桥支架角度不变,所述车轮上设有驱动其转动的车轮驱动机构。与现有技术相比,本发明利用车辆的左右轮差速实现转向,省掉复杂的转向机构,可以降低车辆自身成本和重量,同时车辆还具备扩展的能力。
