12JSD160T-1707030
Sinotruk HOWO
| Attribute | Description |
|---|---|
| Part Name | Auxiliary Box Drive Gear / High-Speed Drive Gear |
| OE Number (Original Equipment) | 12JSD160T-1707030 |
| Common Name | Overdrive Input Gear / High-Range Driving Gear |
| Tooth Count (Z) | Typically 40 teeth or 46 teeth – exact count depends on final drive ratio configuration; must be verified per application |
| Gear Type | Helical gear (for smooth engagement and reduced noise) |
| Material | High-strength alloy steel (e.g., 20CrMnTi or equivalent) |
| Heat Treatment | Carburized, quenched, and tempered for high surface hardness and core toughness |
| - Surface Hardness | HRC 58–63 (Rockwell C scale) |
| - Core Toughness | Optimized to resist shock loading and fatigue |
| Weight | Approx. 4 kg (varies slightly based on tooth count and design) |
| Function | Transmits power from the main shaft to the auxiliary gearbox output in high-range mode, enabling higher-speed operation with reduced engine RPM |
| Location | Installed in the auxiliary (sub) gearbox of dual-stage transmissions |
| Speed Ratio Role | Part of a gear set that defines the high/low range split, typically contributing to an overdrive ratio (~0.79–0.83 depending on model) |
