ZF 16-speed transmission ring gear 16S151 16S181 16S221 16S2230 16S2530
1. Rear Auxiliary Section Planetary Carrier Internal Gear (1315 332 041)
A large, heavy-duty internal gear located in the rear auxiliary section (GP unit) of the transmission; it works with planetary gears to facilitate high/low range shifting.
2. Gear Shift Synchronizer Gear Ring / Synchronizer Ring (1312 315 002 / 1268 304 494)
A conical external gear ring (commonly known as a gear ring) located within the synchronizer assemblies for various gears in the main transmission (e.g., 1st/2nd gear, 3rd/4th gear) or in the front/rear auxiliary transmissions; it is used to synchronize rotational speeds during gear shifting.
3. Main/Auxiliary Shaft Gear Engagement Ring 1312 304 124
A short external-toothed ring press-fitted onto the side of a specific gear on the main shaft; it engages with the synchronizer sleeve to lock the gear in place and directly transmit torque.
