Product Details:

1. Applicable Vehicles and Systems: Designed specifically for the M015 12-speed transmission of HINO 700 series heavy-duty commercial vehicles (including tractors, dump trucks, and concrete mixer trucks); - As the input gear shaft for the 3rd/6th gear of the transmission, it engages with the output gear and synchronizer, and is a core component for power transmission.

2. Optimizes shifting smoothness, reduces power interruption time, and improves power response speed during vehicle starting and climbing.

3. Suitable for high-frequency heavy-duty operating conditions such as intercity heavy-duty transportation, construction site material transfer, and cold chain logistics; compatible with diesel/natural gas powered vehicles, meeting the power system matching requirements under China VI (Euro VI) emission standards, and can operate stably for extended periods in operating scenarios with annual mileage ≥ 200,000 kilometers.

4. Structural Design: The shaft body and gear teeth are integrally formed, with no assembly gaps, and a transmission efficiency of ≥98.5%.

5. Material and Process: Made of 20CrMnTi low-carbon alloy steel, processed through carburizing and quenching, and precision grinding: the tooth surface hardness reaches 60-62 HRC, and the core toughness remains at 24-36 HRC, providing both wear resistance and impact resistance; the internal fiber structure is distributed along the tooth profile, and the fatigue strength is increased by more than 50% compared to ordinary machined gear shafts.
