Title: Corrugated support sleeve for steering column - with controlled wall thickness for rotational strength
Inventor: BURK GERHARD
IPC: B62D1/19
Filed: 1974-08-22
Abstract: The steering column has an impact absorbing section formed by a corrugated wall tube to absorb axial forces and transmit steering forces. In order to strengthen the tube, so that it does not rupture with abnormally high steering forces such as are experienced when driving up a kerb, or when parking on difficult ground, the tube is formed from two half shells joined by two longitudinal seams, with sets of holes to weaken it for axial thrusts. The corrugations are produced by expanding the tube outwards into moulds so that the tops and bottoms of the corrugations have maximum wall thickness. The prepared length of the tube is the same, or longer than the unmodified length. The tube is produced economically with maximum steering strength.
