Overview
Rawsuns E-Axle Gearbox Assemblies (Selection Catalog 26V1) are engineered to seamlessly integrate with our RFD series flat-wire motors. Covering models from R136 to R272, this portfolio delivers a disc-thin, high-torque solution for modern electric mobility. With vehicle load capacities ranging from 1.2T to 6T, these gearboxes support diverse configurations, including options with or without axle housing and brake systems.
Core Advantages
- High Torque & Speed: Supports motor peak speeds up to 12,000 r/min with max output torque reaching 6,750 Nm (R272), ensuring robust performance for heavy-duty cycles.
- Flexible Gear Ratios: Extensive ratio options (e.g., six ratios for R192, 1:16.08 for R272) tailored for specific speed-torque requirements.
- Compact & Lightweight: Optimized axial flux geometry and flange designs (3-hole/4-hole) reduce overall drivetrain volume.
- Precision Engineering: Standardized spline parameters (Input Shaft & Differential) with strict accuracy grades (e.g., 6f GB/T3478.1-2008) for seamless OEM integration.
- Scalable Platform: Proven S9 continuous duty cycle, compatible with 144V–630V architectures, bridging light commercial to extreme heavy-duty applications.
