Abstract

The disclosure relates to an electric power steering system having a rack and a pinion shaft. The pinion shaft meshes with a row of teeth of the rack in an assembled state. To facilitate initial assembly and prevent disengagement during subsequent repair. the rack has an assembly portion at one end of the row of teeth. This portion transitions from the operational teeth and is configured to guide the pinion shaft into engagement. The row of teeth includes first teeth with a first tooth height for normal operation, while the assembly portion has second teeth with a second tooth height that is less than the first tooth height.
