Brogen OESTEA16500ZB is the two-speed version of the 13T bus and trailer electric drive axle platform, designed for applications requiring both strong low-speed torque and efficient highway cruising. It delivers up to 16,500 N·m wheel-end torque through a two-speed gearbox with 33:1 low and 13:1 high ratios, optimizing performance across varied driving conditions.

Powered by a 100/218 kW (rated/peak) motor with up to 500 N·m torque output, it provides reliable traction and stable power delivery for passenger and freight duty cycles. The two-speed architecture enhances drivability while maintaining the same output level as the single-speed ZA variant.

Built on a shared platform housing with the ZA and ZC models, the ZB variant ensures high parts commonality across the product family, simplifying OEM integration and reducing system complexity. With 600A inverter compatibility, it is suited for standard EV drivetrain architectures.

Disc or drum brake options and an 1837 mm wheel track support flexible vehicle integration across bus and trailer platforms.
