A 360-degree rotatable independent suspension

Abstract

The application provides an independent suspension capable of 360-degree rotation. In the field of radiation imaging inspection equipment, mobile radiation imaging inspection equipment has been separated from steel rails and can walk on ordinary roads, and such equipment is referred to as self-walking radiation imaging inspection equipment in the industry. The biggest feature of the self-walking radiation imaging inspection equipment is that it can be transferred to different places for deployment. Because the radiation imaging inspection equipment is large in size, a large turning radius is required when turning, and the equipment is heavy in weight, so the impact force on the equipment is large due to inertia during operation. At present, there is no real suspension device on the self-walking radiation imaging inspection equipment, and only a simple device for driving and turning is provided, which has the problems of large turning radius, inflexible overall direction changing, poor damping effect and inability to meet the equipment transfer under complex road conditions. Therefore, the purpose of the application is to provide an independent suspension capable of 360-degree rotation, which can be used for equipment transfer under complex road conditions.
