Structural Characteristics

1. Combined Main/Auxiliary Box Design: Main box manually operated (6 gears), auxiliary box pneumatically operated (2 ranges)

2. Twin Counter Shaft Drive: Power split design with a floating main shaft and main shaft gears.

3. Fine-Pitch Gearing: Ensures smooth meshing and reduced noise.

4. Optimized Gear Design: Main and auxiliary box gears feature large-radius fillet roots and quasi-involute tooth profiles. Precision controlled via scientific K-diagrams; gears undergo shot peening for enhanced load capacity.

5. Full Synchronizer System: Light and flexible shifting. Main box uses high-capacity double-cone synchronizers; auxiliary box employs reinforced inertial lock-pin synchronizers with non-metallic friction materials for reliable operation.

6. Customizable Options: Clutch housing and release mechanism assembly can be supplied according to customer requirements.

7. Compact & Robust: Short axial dimensions, lightweight construction, high load capacity, reliable performance, and easy maintenance.

8. Optimized Gear Ratios: Reasonable gear progression with small ratio steps. Features a large first gear ratio (15.53) for exceptional heavy-load climbing capability.

9. Precise & Flexible Shifting: Clear gear engagement, flexible shifting operation. Compatible with single-H, double-H, single-stick, double-stick, and cable shift controls.
