Vehicle steering column has two axially engaging column bodies connected to safety device having compressible and incompressible media communicating with each other to apply resetting force in event of crash

摘要

The steering column comprises two axially inter-engaging steering column bodies (1, 2) of which at least one is connected to a safety device (11) comprising an incompressible medium (hydraulic fluid 8) and a compressible medium (air 7) which can communicate with each other and can apply a resetting force opposite the direction of movement of the column bodies in the event of crash. The safety device can comprise a partially filled stroke chamber, movable piston (6) and piston rod as well as a compensating container.
