Novel wheel speed sensor mounting and positioning structure

The utility model relates to the technical field of automobile parts, and discloses a novel wheel speed sensor mounting and positioning structure. The wheel speed sensor comprises a bottom plate, a through hole is formed in the side, close to the induction gear ring, of the bottom plate, a fixing ring is fixedly connected to the outer surface of the wheel speed sensor and penetrates through the through hole of the bottom plate, a clamping groove is formed in the lower surface of the fixing ring, and a limiting block is slidably connected into the clamping groove of the fixing ring. A groove is formed in the side, away from the bottom plate, of the limiting block, a clamping block is inserted into the groove of the limiting block, the fixing circular ring is inserted into the through hole of the bottom plate, the limiting block is pulled out of the clamping groove of the fixing circular ring by pulling the limiting block, and one side of the limiting block abuts against the side, close to the induction gear ri
