Abstract

See full text

An electromechanical steering system may include a reduction gearbox where a worm gear is mounted in first and second bearings rotatably about a longitudinal axis. Rolling elements are disposed between inner and outer rings of the bearings. The inner rings are rotationally fixed on a shaft driven by the worm gear. A spring element is disposed between the inner ring of the second bearing and the worm gear. The spring element has an at least partially annular main body that when installed extends coaxially with the longitudinal axis. Spring arms in a circumferential direction are spaced apart from the longitudinal axis emanating from an external circumferential side of the main body. A first spring arm has a first leg that points away from the longitudinal axis and a second leg on which a free end is disposed, with the second leg running at least partially parallel to the longitudinal axis.
