Power servo electric drive system

Abstract

The invention provides a power servo electric drive system composed of a power assembly, a force sensing mechanism, a steering system and a suspension system. The power assembly is fixedly connected with a wheel base and connected with a guide rail base through two crossed roller guide rails. The force sensing mechanism comprises a force sensor used for receiving tension or pressure generated by sliding of the guide rails when wheels move. The steering system comprises a rotary speed reducer, a speed reducer, a steering motor and an absolute value encoder. The suspension system is used for adjusting the number of springs and the compression amount according to different loading conditions so as to enhance ground adaptability of the system. Compared with the prior art, the system is simple in overall structure, convenient to operate, stable in output power and high in synchronism.

Description

technical field

[0001] The invention relates to the technical field of automation, in particular to a force servo electric drive system. Background technique

[0002] With the rapid development of modern industry and logistics industry, casters are widely used, not only in factories, supermarkets, airports and warehouses, but also in homes. In the prior art, casters mainly include fixed casters and movable casters. Among them, the fixed caster has no rotating structure and cannot rotate horizontally but can only rotate vertically; the movable caster is also called universal wheel, and its structure allows horizontal 360-degree rotation. Generally speaking, different application fields have different requirements for universal wheels. At present, there are several professional universal wheel manufacturers in China. Their product development strives to be flexible and convenient to use, durable, and wear-resistant in different occasions. , Impact resistance, chemical corros...
