Toothed rack for use with push rod in electric power-assisted steering system of car, has toothed zone whose width is greater than outside diameter of body, where plane of top part of teeth in zone is moved relative to axis of body

摘要

The rack (2) has a toothed zone (3) extending over fraction of length of a rack body and placed on a side of a cylindrical elongated body (7) e.g. rod, and a tube with circular section, where width (L) of the toothed zone is greater than outside diameter (d) of the elongated body. The toothed zone is welded against the elongated body and designed as an insertion plate. A tooth is formed directly on the side of the elongated body away from the toothed zone. A plane of a top part of teeth (8) in the toothed zone is radially moved relative to a longitudinal axis of the elongated body.
