No.1017E 2020Special Edition on Automotive Technologies High Efficiency Hub Unit

Category NEW PRODUCT
Author West JAPAN Technical Center, Bearings Business Unit
Abstract In order to respond to the recent trends of strengthening CO2 emission restrictions, further torque reduction is required to wheel hub units for fuel consumption improvement. However low friction torque and high reliability (sealing performance) are incompatible, and diffi cult to satisfy both performance at the same time. JTEKT has developed and mass-produced a high efficient hub unit with low friction torque and high reliability in order to respond to the market demand, by adopting JTEKT’s original low friction torque technology, HUB_LFT® (Low Friction Torque). This report presents the development results of low friction torque and high reliability hub unit.
