Abstract
A passive sensor device of hub bearing unit used in non-drive wheels, which comprises a shell, a coil winding and a magnetic body. The utility model is characterized in that a fixing frame which is inlayed inside the shell is hollow, with one end open and the other end closed. A junction pole is arranged on a confining surface, and the shape of the fixing frame meshes with the inside part of the shell. The cross section of the lateral wall of the fixing frame is s-shaped, and from the bottom to the port a ring-shaped groove 1 and a ring-shaped groove 2 is formed on the outside and inside of the lateral wall respectively. A magnetic steel is inlayed inside the groove 1, and the coil winding is intertwined inside the groove 2 and a bush is arranged on the groove 2. A ferrule which is buttoned on the outside wall of the fixing frame clips the coil winding therebetween. The utility model has the advantages of simple and reasonable structure, low manufacturing cost, and convenient positioning.
