Track induction device of track-laying vehicle

The invention discloses a track induction device of a track-laying vehicle. The track induction device comprises a plurality of track shoes, and each track shoe is provided with a track pin. The track induction device is characterized in that every two adjacent track pins are connected through an induction part, each induction part comprises an induction tooth, a tooth guiding cover and a connecting part for connecting the induction tooth and the tooth guiding cover, and two semi-circular arcs are arranged on the two sides of each induction tooth and the corresponding tooth guiding cover in a matched mode and respectively connected with the corresponding track pins. Detachable induction is achieved, the induction tooth structures are independent, a forging technology can be adopted, and reliability of parts after forging can be improved substantially. A hollow structure is adopted for the induction teeth so that the purpose of reducing weight can be achieved, and at the request of the same weight, the height of the induction teeth can be increased appropriately by the adoption of the structure, so that the induction performance is more reliable.
