Detailed ways

The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

The specific embodiment of the present invention is as follows: as shown in Figures 1-6, a transmission sleeve includes a transmission shaft 1, and one end of the transmission shaft 1 is provided with a signal plate 2, and the signal plate 2 is used to obtain the engine cam phase signal, The end face of the other end of the transmission shaft 1 is axially protruded with a transmission tooth 12 for transmitting power. The transmission shaft 1 is provided with a positioning hole 11 arranged through both ends of the transmission shaft 1. The positioning hole 11 plays a positioning role to ensure that the transmission shaft 1 Quick connection with the external structure to improve assembly efficiency; the transmission sleeve adopts an integrated design, and the transmission shaft signal plate is integrally formed, which reduces the number of parts of the internal combustion engine, and conforms to the concept of lightweight design and lean design; the assembly process is good, The assembly efficiency is improved. After the integrated design is adopted, the bolt transition connection between the parts is reduced, and the reliability is good; moreover, the integral molding structure has compact structure, small space occupation, high structural strength and stable torque transmission.
