This paper discusses the change in vehicle parameters when moving from a conventional internal combustion engine to electric motor. It discusses the impact on the wheel end bearings. Typically these include higher GAWRs (Gross Axle Weight Rating) at lower center of gravity heights. These changes require bearings to handle higher loads. Typically, larger loads will increase the bearing size and with it the mounting interface dimensions to auxiliary components. Timken demonstrates an alternative bearing design that can handle higher vehicle GAWRs but would allow for continuity in the surrounding brake corner components – saving OEMs significant design costs and delays.
