Rawsuns READ42000Z: Two-Gear Electric Axle for 13t Heavy-Duty TrucksIntroducing the READ42000Z (Heavy-Duty Truck E-Axle 1.6 Generation)—a two-gear electric drive axle built for 13t axle load, tailored to 6x4/4x2 heavy trucks, delivering industry-topping power for commercial e-mobility.
Core Highlights & Key Specs
* Unmatched Torque: 200/320kW motor power (366/650N·m torque) + 4 gear ratios → 42000N·m wheel-end torque (dominant traction for heavy payloads).
* Optimized Design: 110km/h max speed, stamped-welded axle housing, and 985kg total weight (with air suspension accessories), plus adjustable spring pitch for flexible chassis fit.
* Reliable Safety: Drum brakes (φ410×220) + 2×18000N·m braking torque, ensuring stable stopping power for high-capacity operations.
Ideal for 6x4/4x2 heavy e-trucks, the READ42000Z combines two-gear versatility, 40000N·m peak torque, and robust engineering to elevate heavy commercial electric vehicle performance.
