Sheet steering wheel - has skeleton formed by one or more separating steps combined with deformation producing no chips to produce final shape

摘要

The sheet steering wheel (1) has a hub (2), spokes (3) and a crown (4). It is made in one piece from a single sheet cutout (5), brought to its final shape by one or more separating steps combines with deformation, producing no chips. - The hub region has a cone (6) on the vehicle side. There are borings (7), through stampings (8) or screw holes (9) in the spokes, which run upwards and outwards. An airbag module may be fitted by means of these borings. A nut can be pressed in a through stamping. The hub zone can be strengthened by doubling the material.
