Problems solved by technology

[0003] Most of the existing robot chassis use two-wheel drive plus one or more driven wheels, and the steering is through differential steering. This steering method will rub the wheels, resulting in a greatly shortened service life of the wheels. Insufficient obstacle avoidance ability, once some obstacles are encountered, it is easy to cause the entire chassis to topple

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of robot chassis, in particular to a robot chassis with four-wheel independent steering. Background technique [0002] The robot chassis is used to support the whole vehicle components, and can control the forward, backward, turning and other traveling modes of the robot. The range of turning radius can rotate in situ. [0003] Most of the existing robot chassis use two-wheel drive plus one or more driven wheels, and the steering is through differential steering. This steering method will rub the wheels, resulting in a greatly shortened service life of the wheels. The ability to avoid obstacles is insufficient, and once some obstacles are encountered, it is easy to cause the entire chassis to topple. Contents of the invention [0004] The purpose of the present invention is just to provide a kind of simple in structure, a kind of four-wheel independent steering robot chassis of reasonable design in order...
