Detailed Description

In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.

As shown in fig. 1-6, the utility model discloses a drive sprocket for PHEV thoughtlessly moves automobile engine, including sprocket main part 1, the outside border of sprocket main part 1 is equipped with a plurality of sprocket teeth 2, the central point of sprocket main part 1 puts and is equipped with axle mounting hole 11, sprocket main part 1 is equipped with the supporting section of thick bamboo 3 of axle dress with the axle center with sprocket main part 1, sprocket main part 1 is equipped with the mounting groove 12 corresponding with the supporting section of thick bamboo 3 of axle dress, sprocket main part 1 is equipped with a plurality of laser etching lines 13 with axle mounting sleeve 3 assorted, the both sides of laser etching line 13 are equipped with lines arch 14, laser etching line 13 sets up around sprocket main part 1 center, sprocket main part 1 is equipped with a plurality of fretwork round holes 4, the centre of a circle of fretwork round hole 4 sets up around the center of sprocket.

In the embodiment, when the transmission chain wheel is used, the shaft is arranged in the shaft assembling sleeve 3 and is locked and fixed through the shaft mounting hole 11, and the friction coefficient of the mounting surface of the shaft can be realized through the design of the laser etching line 13, so that larger torque can be transmitted after the assembly; the line protrusions 14 can further increase the friction coefficient between the line protrusions and the shaft mounting surface; in addition, the hollow round hole 4 can reduce the weight of the chain wheel main body 1, so that the chain wheel is more convenient to use, and materials can be saved; and when special requirements are met, the hollowed-out round holes 4 can also be used as mounting holes.
