Device for supporting ball nut of ball screw mechanism for motor vehicle power steering, has flexible spring regions, each joining housing and inner race attachment regions of outer race of receiving element

摘要

A receiving element (13) includes an outer race (14) mounted to a mechanism housing through circumferentially spaced attachment regions (16), and an inner race (15) supporting the bearing (12) of the ball nut (9) and joined to the outer race through integral, circumferentially spaced attachment regions (17). A flexible spring region (18) is integral between each housing side attachment region (16) and each inner race attachment region (17).
