STEERING COLUMN SYSTEM


  1. CONSTRUCTION


    1. Models with Manual Tilt and Manual Telescopic Steering Column


      1. The steering intermediate shaft assembly and steering column assembly each contain an energy absorbing mechanism.

    2. Models with Power Tilt and Power Telescopic Steering Column


      1. The steering intermediate shaft assembly and steering column assembly each contain an energy absorbing mechanism.

      2. The column tube is of double tube construction with the 2 tubes connected via a tolerance ring.

  2. OPERATION


    1. Models with Manual Tilt and Manual Telescopic Steering Column


      1. Primary Collision


        • The steering intermediate shaft assembly contracts during a primary collision (vehicle to another object) to reduce the possibility of the steering column assembly and the steering wheel assembly protruding further into the cabin.

      2. Secondary Collision


        • The steering column assembly contracts during a secondary collision (driver and vehicle) in order to absorb impact. The breakaway pin on the lower housing shears and disengages the telescopic lock hook to move the steering wheel assembly toward the front of the vehicle. As the steering column assembly contracts, the column tube slides on the inner surface of the lower housing, generating friction and absorbing the energy of the collision.

      2. Secondary Collision


        • The column tube of the steering column assembly contracts during a secondary collision (driver and vehicle) in order to absorb impact. As the column tube contracts, the inner tube is pushed out of the tolerance ring and further into the outer tube, generating friction and absorbing the energy of the collision.
