The ZL30J drive bridge, produced by Jiangxi Fenyi Drive Bridge Co., Ltd, consists of a bridge housing, main transmission, half‑shafts, wheel‑side planetary reducer, and disc brake. Its planetary reducer and dual spiral bevel gears change power direction, reduce speed, and increase torque before delivering power to the driven wheels.
