Abstract
The utility model discloses a pivot bracket vibrating signal collecting base, which is provided with a base with the steps inside. The base is fastened with a close shaft in the inside. Between the base and the close shaft, a bearing is coupled with a shaft sleeve which is coupled with the close shaft, wherein the close shaft is connected with the shaft sleeve through a screw thread. One end of the bearing is opposite to the step inside the base, while the other end is provided with a bearing end cover and the two ends push against each other. The bearing end cover is coupled with the shaft sleeve and is constantly connected with one end of the base. A changeover panel is fastened on the other end of the base. A hole that is wider than the diameter of the close shaft in width is formed in the changeover panel. One end of the close shaft passes through the hole and projects out of the changeover panel. The other end of the close shaft projects out of the shaft sleeve. The base with the structure can make the sensor collect the information about the vibrating signal of the wheel along the three coordinate directions with reliability and efficiency, and meanwhile will not make the signal line of the collecting set inside the car be interwoven by the wheel.
