Advantage | Technical Details | Industry Impact |
---|---|---|
Ultra-Quiet Operation | - Helical tooth design with 15° modified lead angle - Surface finish: Ra 0.4μm (grinding after milling) - Dynamic balance: G2.5 (ISO 1940) |
Reduces cabin noise to <55dB at 8,000 RPM (vs. 70dB for standard gears), aligning with xEV luxury brand requirements (e.g., Tesla, BYD Yangwang). |
EV-Grade Durability | - Material: Powder-metallurgy 20CrMnTiH (grain size 10-12ASTM) - Heat treatment: Plasma nitriding (550HV surface hardness, 1.2mm case depth) |
Passed 2,000-hour salt spray test and 10 million-cycle fatigue test (ISO 6336-5:2003), 30% longer lifespan than cast gears. |
Precision Milling Innovation | - 5-axis CNC milling with diamond-coated tools - Tooth profile correction: 0.02mm crowning & tip relief |
Eliminates backlash (<0.05mm) and ensures 100% contact ratio, critical for seamless one-speed gearbox integration (e.g., Porsche Taycan's 2-speed e-drive). |
Lightweight Design | - Hollow-web structure with FEA-optimized ribs - Weight: 2.1kg (15% lighter than forged counterparts) |
Contributes to 0.15kWh/100km energy savings in xEVs, aligning with EU's 2035 carbon-neutral goals. |
