What is the requirements for gearbox shift fork production?

　　The gearbox shift fork is more unfamiliar to us, in fact it is a U-shaped fork, we can distinguish it very well through appearance. What is the requirements for the fork production process? Let's take a look at it.

　　The transmission shift fork is pushing the sliding gear. There is a loop in the sliding gear, and the fork is riding in this loop. When the car driver pushes the shift lever, the shift lever will drive a good The fork shaft, then the fork shaft has the continuing to drive the fork, the fork is pushed to push the gear, so that the purpose of shifting can be achieved.

　　Although the gearbox replacement fork is special, but the structure is simple, it belongs to a typical forked part. In order to achieve shift, variable speed, its fork shaft holes and variable speed strips need well, so the machining accuracy is high.

　　The on-end faces need to withstand the impact load in operation, in order to enhance its wear resistance, the surface requires high frequency quenching treatment, the hardness is 48-58 hrc; in order to ensure the force of the fork shift; required fork two The verticality requirements of the end face to the hole φ22 are required to be 0.07 mm.
