The invention relates to a method to manufacture electric power steering systems (10). First, an electric motor (20) having a drive shaft (24), a coupling device (26), and a worm gear (12) having a worm shaft (16) are provided. Then, an adjusting sleeve is provided, and an individual axial position of each adjusting sleeve in its associated opening is determined in order to achieve a specific axial preloading force on the worm shaft. The adjusting sleeve (34) is press-fitted into the axial opening (32) in the determined axial position, and a spring element (44) is installed in the adjusting sleeve (34) so that the spring element is supported on one end axially on the drive shaft and on its other end it is supported axially on the adjusting sleeve (34), and said spring element acts upon theworm shaft with the preloading force in the axial direction via the adjusting sleeve. In addition, also described is an electric power steering system.
本发明涉及一种用于制造电动助力转向系统(10)的方法。首先,提供具有驱动轴(24)的电动机(20)、联接装置(26)和具有蜗杆轴(16)的蜗轮蜗杆传动机构(12),蜗杆轴在其配设给电动机的端部上具有轴向开口(32)。提供调节套筒并且确定每个调节套筒在其配设的开口(32)中的单独的轴向位置,以便实现在蜗杆轴上作用预定的轴向预压紧力。将调节套筒(34)压入轴向开口(32)中的规定位置中并且将弹簧元件(44)安装到调节套筒(34)中,使得弹簧元件在其一个端部上轴向支撑在驱动轴上并且在其另一端部上轴向支撑在调节套筒上,并且弹簧元件通过调节套筒(34)以预压紧力沿轴向方向加载蜗杆轴。此外,描述了一种电动助力转向系统。
