Embodiment Construction

[0018] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, the chassis of an all-round mobile platform vehicle with stepless wheelbase adjustment provided by the present invention adopts a modular design concept and includes four modules. Among them, the structure of module 1 and module 2 is symmetrical, the structure of module 3 and module 4 is symmetrical, the structure of module 3 is completely consistent with that of module 1, and the structure of module 4 is completely consistent with that of module 2. The modular design is convenient for mass production and processing. It is not necessary to produce the entire platform chassis. It only needs to produce modules 1 and 2 in batches, and then connect the four modules through ball screws to form a platform chassis.

[0020] Such as figure 1 and figure 2 As shown, module 1 includes Mecanum omnidirectional wheel ...

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...
