Abstract

The invention discloses a transportation robot. Under the control of an electric control module, torque output by a steering assembly is transmitted to an inner shaft sleeve, the inner shaft sleeve transmits the torque to a sliding column, a driving wheel is driven by the sliding column to steer, and therefore, independent steering control over all wheels is achieved, and steering is flexible; each driving wheel is provided with an independent suspension mechanism, the suspension mechanisms are located over the driving wheels, so that the effective action distance of the suspension mechanismsis increased, and the lateral rigidity is good; the load state and the speed are designed in a matched mode, so that it is guaranteed that the robot can rapidly run in a no-load state, and good obstacle crossing capacity is achieved; when the robot is in full load, the robot operates at a low speed, and all the driving wheels have good ground attaching performance, so that the suspension phenomenon is avoided, it is ensured that the robot has sufficient power performance; and the robot has good stability and accurate positioning performance when the robot is in full load.

Description

technical field [0001] The invention relates to AGV equipment, in particular to a transport robot. Background technique [0002] At present, AGV (Automated Guided Vehicle, referred to as AGV) has been widely used in logistics warehousing and transportation, material transportation, industrial production enterprises and assembly lines. Moreover, the suspension mechanism does not have the function of overcoming obstacles, so the applicability is not strong on uneven roads or poor venues, and slipping or overhead phenomena often occur. Due to the limited installation space of the chassis structure of the traditional AGV, and the complex structure of the suspension of the driving wheel, some products on the market are equipped with a simple suspension device on the driving wheel. This suspension device can solve the problem of the driving wheel hanging and slipping to a certain extent. , but in the process of AGV heavy load start and stop, the chassis shakes obviously, which is...
