Detailed ways

The present invention will be further described below in conjunction with accompanying drawing:

With reference to the accompanying drawings: the motorcycle racing engine in the present embodiment comprises left box body 1 and right box body 2, and left box body 1 is connected with right box body 2, and left box body 1 is provided with starter motor 3, left box body 1 The box body 1 and the right box body 2 are provided with a magneto stator 4 and a magneto rotor 5, the output end of the starter motor 3 is connected with the magneto rotor 5, and the magneto rotor 5 is connected with a crank connecting rod assembly 6, a crank The connecting rod assembly 6 is arranged in the left box body 1 and the right box body 2 .

Arranged in this way, a starter motor 3 is added on the engine, and the output end of the starter motor 3 is connected with the magneto rotor 5. When starting, the magneto rotor 5 is directly driven by the starter motor 3 to rotate and work, and the magneto rotor 5 is combined with the crank connecting rod 6 are directly connected to form the armature of the starter motor 3, and the crankshaft of the crank-connecting rod combination 6 is directly driven by the starter motor 3, thereby increasing the starting speed, high starting speed, strong performance, saving space, higher transmission efficiency, and low after-sales cost , Changed the previous structure that needs to drive the crankshaft through reduction gears, one-way clutches and other structures, reduces the use of parts, saves space, has high transmission efficiency, and reduces after-sales costs.

The shell magnet of starter motor 3 is the shell magnet of starter motor 4 made of rare earth material. Arranged like this, the magnet on the starter motor 3 housing is a rare earth material, and after the engine is started, it can also generate a large amount of electric energy to supplement the electric quantity of the engine storage battery.

The crank-rod combination 6 is sequentially connected with a piston 7, a driven gear 8, a clutch 6-1, a recoil start combination 9, a ratchet combination 10, a pedal combination 11, a piston 7, a driven gear 8, a clutch 6-1, The recoil starting combination 9 and the ratchet combination 10 are all arranged in the left casing 1 and the right casing 2, and the right casing 2 is provided with a right casing cover 12 outside, and the pedal lever assembly 11 is positioned outside the right casing casing 12.
