Embodiment Construction
[0017] see figure 1 The magneto-acoustic valve device for exhaust system tailpipe noise control of the present invention comprises an exhaust pipe 1, a valve plate 2, a rotating shaft 3, a steel wool bushing 4, a magnet 5, and a magnet protection cover 6; Holes are opened on the side, the steel wool bushings are respectively fixed in the holes, the rotating shaft is fixed in the steel wool bushings, the valve plate is welded on the rotating shaft, and the magnet is welded directly below the valve plate through the magnet protection cover.
[0018] The working principle of the present invention combines figure 1 described as follows:
[0019] The restoring force required by the valve plate is provided by the magnetic force of the magnet 5 and the gravity of the valve plate 2 itself to replace the function of the spring. At low speed, the torque and power required by the car are relatively low, and the back pressure requirement is also relatively low, but The requirements for...
