It consists of one-way clutch, driving gear and shifting fork. Its function is to make the driving gear mesh with the non-gear ring gear when starting the engine and transmit the torque of the starter. After the engine is started, the driving gear can be automatically separated from the flywheel. In the process of their separation, when the engine flywheel drags the driving gear backward, the one-way clutch makes it idle, preventing the flywheel from driving the starter shaft to rotate.
R&D history:
1740, the first motor was a simple electrostatic device invented by andrew gordon, a Scottish monk. 1827, Hungarian physicist Anyouxi Jedlik (? NyosJedlik) began to try to do experiments with electromagnetic coils. After solving some technical problems, Jedlik called his equipment "electromagnetic dumper".
Although it is only used for teaching purposes, the first Jedlik equipment already contains three main components of today's DC motor: stator, rotor and commutator.
1836, Thomas Davenport, an American blacksmith, manufactured the world's first applied motor that can drive a small tram, and applied for a patent in 1837. Davenport went bankrupt because of the high cost of main battery and commercial failure. Some inventors continue to develop and apply motors, but they all encounter the same problem of battery power generation cost.
