Steering Column: Description and Operation
Steering Column: The upper steering column with crash element can be compressed telescopically by 70 mm when the steering column is subject to load in the event of a crash. This telescopic action is controlled by a crash element made of fiber glass reinforced plastic.
The compression movement begins when the three plastic pins shear under an axial force of approximately 3 kN.
The telescopic adjustment splines inter-slide allowing compression when the crash element is deformed over a defined length (at a force of 3 to 7 kN).
