Steering Column; Yield Point Fastening - Alfa Romeo 159 Training Material

STEERING

7.1.4 Steering column

With telescopic sleeves, the column ensures:
vertical rotation with a stroke of ± 2°
axial adjustment with 45 mm total stroke.
The fastening lever under the upper sleeve in the specific compartment under the lower upholstery complies with the
most recent EUNCAP safety indications.
The standard electrical steering column lock is housed in the lower steering sleeve near the anchoring bracket to the
dashboard crossmember. In this way, it is away from the knee area, according to current EUNCAP requirements. In
compliance with current European standards, the device locks the steering column with a specific Rencol clutch
bushing that allows rotation at torque comprised in the range from 100 to 240 Nm to prevent damage to mechanical
parts of the steering system in the event of attempt to steal the car.
The steering column has a controlled energy absorption collapsing device with an axial stroke of 45 mm in addition to
the adjustment stroke.
The high handling comfort objective is expressed on steering column design by its high structural stiffness by using a
metal structure that does not penalise weight. Similarly, a new intermediate shaft design has been adopted with a
high decoupling torsional damper capable of filtering the vibrations from the steering box without compromising
handling accuracy and preventing the feeling of lightness in the middle.
