Signalling device for limiting speed of vehicle

The utility model discloses a signalling device for limiting speed of vehicle, comprising a pulse generator fixedly mounted on the left cover of the engine and close to the outer cover of the clutch. The signal output line of the pulse generator crosses the left cover and connects with the igniter through a cable. The outer cover edge of the clutch is provided with a lug. The mounting position of the pulse generator which is on the left cover of the engine enables the clutch lug to cut the magnetic force line of the pulse generator when the device working, and thus generates pulse signals. The device can directly get the actual signal of the speed of vehicle from the rotating speed of the clutch. Owing to the precise signalling, the device can genuinely achieve the goal of limiting the top speed of the motorcycle, and solve the problems of low speed triggering and overproof emission caused by the former speed-limiting signalling methods which have strong impact on the performance of motorcycle. The utility model can be widely applied to four wheelers such as motorcycle, dune buggy, carriage for children, and golf carriage, etc., which adopt belt driving and stepless speed changing engine.
