Ring Gear Carrier AZ9981340020 AC16 for Howo Sinotruk Heavy Duty Truck Axle

This ring gear carrier (also known as齿圈支架 or planetary ring gear carrier) with part number AZ9981340020 is specially designed for the AC16 heavy duty axle used on Howo Sinotruk trucks. It is a critical component of the wheel hub planetary reduction system, providing the structural housing that supports the ring gear and houses the planetary gears at the wheel end.

The ring gear is bolted or pressed into this carrier, and together they work with the sun gear and planetary gears to provide torque multiplication and speed reduction at the wheel hub. Made of high-strength ductile iron casting with precision machining, it features excellent structural integrity, wear resistance, and long service life. The precision-machined internal gear mounting surface and bearing journals ensure proper alignment and smooth operation of the planetary gear set. The robust construction is specifically engineered to withstand the extreme torque forces encountered in heavy duty on-road and off-road applications.
