Abstract: A composite tubular housing for an automotive steering system, preferably an electronic power assist steering system, is formed of seamless metal tube section welded into an integral component. The housing includes a rack section and a pinion section having an opening that is welded to the rack section. A yoke section is formed of a tube having an end that is welded to the rack section opposite the pinion section. The pinion section may contain a drive pinion coupled to a steering wheel of the vehicle. The housing may also include sections for an assist pinion coupled to an electric motor, and a yoke which are attached to the rack section apart from the drive pinion.

Abstract translation: 用于汽车转向系统的复合管状壳体，优选地是电子助力转向系统，由无缝金属管段形成，焊接成一个整体部件。 壳体包括齿条部分和具有焊接到齿条部分的开口的小齿轮部分。 轭部由具有焊接到齿条部的与小齿轮部相对的端部的管形成。 小齿轮部分可以包含联接到车辆的方向盘的驱动小齿轮。 壳体还可以包括用于耦合到电动机的辅助小齿轮的部分和连接到与驱动小齿轮隔开的齿条部分的轭。
