METHOD OF CONNECTING NON-SYMMETRICAL INSIDE DIAMETER VEHICLE SPINDLE TO STATIONARY HOUSING AND AXLE ASSEMBLY

摘要

A process for connecting a non-symmetrical inside diameter vehicle spindle to a stationary housing is provided. Low and high stress areas of the spindle are determined, where correspondingly reduced and increased material cross sections are provided or increased cross sections are located in an orientation relative to a spindle axis. Consequently, the low and high stress areas of the spindle are aligned with corresponding areas of the stationary housing. Then, the spindle and stationary housing are connected by way of friction welding. This in turn results in selecting a section modulus of the connection of the spindle to the stationary housing, thereby achieving the lowest weight to strength ratio for the connection.
