Parámetros básicos del producto
Part OE No.: AZ220310000019 (Replacement)
WG2203100244)
Product Name: Low Gear Taper Assembly (Transmission Range Low Gear
齿毂)
Applicable models: Sinotruk 70 mine dump truck, Howo, Steyr,
Shankaka F Series Speedbox
Installation location: High and low speed switchingmechanism for transmission auxiliary box. Materialprocess: 40Cr alloy steel integrated forging, overallcarburizing and hardening, precision gear grindingprocessing
Ventajas principales del producto
1. Original factory drawing mold opening and full matching of dimensions
Strictly align with original factory data, internalsplines, external teeth, installation conical surfaceaccuracy, seamless assembly, no need for grindingor modification, and higher maintenance efficiencyat the repair shop.
2. Alloy steel carbon quenching, heavy-duty wear resistance, and durable
Overall forging + deep carburizing heat treatmentprovides high tooth surface hardness. Frequentlow-speed gear shifting during heavy loads in minesand construction sites is less likely to cause toothdamage and wear, significantly extending service life.
3. Smoothly switch to high and low speeds, resolvingcommon transmission faults. Combine with thesynchronizer to achieve high and low speed switching inthe auxiliary box, effectively improving issues such aslow-speed gear shifting, lag during gear shifting,abnormal noise during high and low speed switching,and weak slope climbing.
4. Impact resistance to harsh operating conditions, suitablefor heavy-duty mining vehicles. Optimized for the heavy-loadoperating conditions of 70 mine dump trucks, the conical millstructure offers higher strength and is less likely to deformand crack under heavy-load road conditions
5. Sufficient stock available, domestic wholesale + fullcontainer supply for foreign trade. Jinan heavyequipment warehouse maintains regular inventory,supplying repair shops and auto parts wholesalersnationwide; it can also provide export packagingdocuments and support shipments from FOB Qingdaoand Tianjin ports.
Itis recommended to replace the fault scenario.
1. The auxiliary box of the vehicle shifts duringlow-speed driving and automatically shifts tohigh-speed gear.
2. Severe lag and abnormal tooth noise whenswitching to high speed.
3. Gearbox disassembly reveals wear, toothchipping, and loose splines.
4. Poor power connection and gear shifting failure when climbing heavy-duty slopes in the mine vehicle
5.Major overhaul of the transmission auxiliary box and complete maintenance and replacement of the high and low speed mechanisms
