Power steering apparatus for motor car, has drive unit that is movable in translation relative to steering column when drive unit reaches maximum fixing force that is parallel to longitudinal axis of steering column

摘要

The apparatus has a torque electric drive unit (2) with a specific initiating fixed to move to a seat (6) against a predetermined fixing force due to a particular accidental external force (4) from an operating position to a crash position. The drive unit is fixed by a fixing element that extends in a longitudinal axis (5) of a steering column (1). The drive unit is movable in translation relative to the steering column when the drive unit reaches maximum fixing force that is parallel to the longitudinal axis of the steering column.
