Wheel track stepless regulation type omnibearing mobile platform truck chassis

Abstract

The invention provides a wheel track stepless regulation type omnibearing mobile platform truck chassis for industrial and agricultural transport. Modular design concept is adopted in the wheel track stepless regulation type omnibearing mobile platform truck chassis. The whole car chassis comprises four modules, structures of a module 1 and a module 2 are in a bilaterally symmetrical type, a module 3 and the module 1 are identical in structure, and a module 4 and the module 2 are identical in structure. The module 1, the module 2, the module 3 and the module 4 are connected through ball screws in sequence, and the module 4 is connected with the module 1 through another ball screw. In each module, a direct-current servo motor drives a small synchronous wheel to rotate, a synchronous cog belt transfers power to a large synchronous wheel to drive an axle to rotate, and Mecanum omnidirectional wheels are driven to rotate. By means of the wheel track stepless regulation type omnibearing mobile platform truck chassis, a platform truck can move forwards, move transversely and perform pivot steering, transport under the conditions of lack of space is achieved effectively, and stepless regulation can be performed on the wheel track of the platform car according to the width of the road and the volume of loads.

Description

technical field [0001] The invention relates to a chassis of a mobile platform vehicle used in industrial and agricultural transportation, in particular to a chassis of an all-round mobile platform vehicle with stepless adjustment of wheelbase. Background technique [0002] With the development of society and economy, in the fields of medical care, logistics, facility agriculture, aerospace and other fields, in order to reduce the intensity of human work and improve efficiency and reliability, a large number of auxiliary, autonomous transport vehicles and robots are needed. The mobile mechanism of the platform vehicle, which is the foundation of robots and transport vehicles, has attracted much attention. At present, the ground mobile platform vehicles have various forms such as wheel type, crawler type, and leg type, among which the wheel type mobile system is the most reliable and widely used. Compared with other forms of mobile systems (crawler type, snake type, etc.), t...

Problems solved by technology

[0003] However, ordinary wheeled moving mechanisms require a certain turning radius. If the working space is narrow, it will not be able to turn or move laterally.

Moreover, the wheel base of ordinary wheeled mobile platform vehicles is fixed, cannot be adjusted, and cannot adapt to different road conditions and load sizes.
