Reducer for B class and above vehicles, including commercial vehicles, with an oil cooled design and integrated electronic oil pump and cooler.
Forced lubrication and an optimized flow channel design keep the unit efficient under sustained high load, even in extreme operating conditions.
ET450 integrates an electronic oil pump, oil cooler, and a reserved parking interface into a single compact layout, sized for B class and above vehicles, including commercial applications. Forced lubrication of the reducer bearings addresses oil flow distribution during low temperature startup, a common challenge in this class of unit, improving adaptability to extreme operating conditions.
An optimized system layout and tank flow channel design reduce high speed oil agitation losses by 20%, improving overall assembly efficiency. Gearing uses a fine, tall tooth profile with a high contact ratio for strong NVH performance at both low and high speeds. Replaceable filter elements improve maintainability and extend service life.
