Intelligent ball head, application method and vehicle

The invention discloses an intelligent ball head, an application method and a vehicle, according to the road surface condition evaluation method, a magnetic sensor is arranged in a ball head joint and used for monitoring the rotation condition of the ball head, so that the movement condition of vehicle wheels can be analyzed, and when the wheels run to a raised road surface or a pit road surface, the wheel movement condition can be analyzed; under the action of the shock absorber, the wheels can quickly move upwards or downwards, so that the scheme performs data acquisition on the movement of the ball head to reversely deduce the road condition, has the characteristics of reasonable structure, simple operation and accurate feedback, realizes the marking operation of the road condition defects of various roads under a large amount of data records, and improves the working efficiency. Maintenance reminding operation can be provided for departments such as road administration, or marking points can be provided f
