Automatic synchronous clutch with high-speed pawl mechanism and low-speed pawl mechanism

The utility model discloses an automatic synchronous clutch with a high-speed pawl mechanism and a low-speed pawl mechanism. An input shaft and a sliding assembly are connected through outer spiral teeth and inner spiral teeth, and outer driving teeth of the sliding assembly are connected with inner driving teeth of an output toothed ring through a gear in a meshed mode. A low-speed ratchet wheel is arranged on the outer circle of the sliding assembly, and a low-speed pawl is arranged at the position of an inner hole of the output toothed ring. A high-speed ratchet wheel is arranged at the position of an inner hole of the other end of the output toothed ring, and a high-speed pawl is arranged on the outer circle of the sliding assembly. The input shaft and the sliding assembly are connected through the outer spiral teeth and the inner spiral teeth, when the input shaft and the sliding assembly rotate in place in one direction relatively, the inner driving teeth are meshed with the outer driving teeth in a connected mode, and when the input shaft and the sliding assembly rotate in place in the other direction, the inner driving teeth and the outer driving teeth are disengaged from each other to be not meshed. Due to the fact that a conventional automatic synchronous clutch is changed into the automatic synchronous clutch with the high-speed pawl mechanism and the low-speed pawl mechanism, the using safety is improved, and the maintaining cost is lowered.
