It mainly transmits power to the wheels through cooperation with the gearbox, drive axle, etc. to achieve the engagement and separation of all forward gears.

[0003] The auxiliary positioning device for automobile fork shaft processing is a device or tool used to provide accurate positioning and stable support during the processing of automobile fork shafts.
