Abstract

A rack-and-pinion steering system, in particular for a motor vehicle, has a steering housing and a pinion which is inserted into the steering housing If. A rack whose toothing engages with the pinion is mounted so as to be axially displaceable in the steering housing. The rack-and-pinion steering system has a circulation lubrication system with lubricating oil, an arrangement for conveying lubricating oil from a lubricating-oil reservoir conveying lubricating oil to the toothing engagement location between the rack and the pinion.
