Independent suspension capable of rotating by 360 degrees

Abstract

The invention provides an independent suspension capable of rotating by 360 degrees. In the field of radiation imaging inspection equipment, mobile radiation imaging inspection equipment gets rid of a steel rail, can walk on a common road surface, and is called as self-walking radiation imaging inspection equipment in the industry. The biggest characteristic of the self-walking radiation imaging inspection equipment is that the self-walking radiation imaging inspection equipment can be transferred and deployed at different places. Due to the fact that radiation imaging inspection equipment is large in size, a large turning radius is needed during turning, and due to the fact that the equipment is heavy in weight, impact force on the equipment is large due to the inertia effect in the running process. At present, self-walking radiation imaging inspection equipment is not provided with a real suspension device, is only a set of simple device for driving and steering, and has the defects of large turning radius, inflexible overall direction change, good damping effect and incapability of meeting equipment transition under complex road conditions. Therefore, the invention aims to provide an independent suspension capable of rotating by 360 degrees, and equipment transition can be carried out under complex road conditions.
