Abstract
A motor vehicle steering gear with a gear rack and a drive pinion that meshes with it, which drive pinion comprises a rigidly attached drive projection in a rotational bearing that is on a front face and eccentric to the pinion teething for coupling a motor vehicle steering spindle, said rotational bearing being guided in a direction transverse and parallel to a diametrical plane formed by the pinion teething, such that when the pinion is rotating, compensation strokes for the rotational bearing are specified in a direction transverse to the gear rack, said compensation strokes being caused by the eccentric attachment of the drive projection, a retaining projection rigidly attached at a front face concentrically to the pinion teeth, the retaining projection being rotatably in engagement with the retaining piece that is guided within a gear housing parallel to the gear rack teeth, is and that during pinion rotation compensation strokes parallel with and at a constant distance to the gear rack teeth are specified, which compensation strokes are caused by the eccentric attachment of the driving projection.
