STEERING COLUMN SYSTEM DETAILS


  1. CONSTRUCTION


    1. Manual Tilt Mechanism


      1. The manual tilt mechanism allows adjustment of the steering wheel position in the vertical direction through lever operation. This provides the driver with the most comfortable driving position.

      2. The manual tilt mechanism is locked using the tilt lever.

    2. Energy Absorbing Mechanism


      1. The energy absorbing mechanism in the steering column consists of a lower bracket, an energy absorbing plate, a breakaway bracket, a steering sliding with coupling yoke sub-assembly and a No. 2 steering intermediate shaft sub-assembly.

      2. The steering column is mounted onto the instrument panel reinforcement via the lower bracket and the breakaway bracket. The steering column and the power steering link assembly are connected by the contractile No. 2 steering intermediate shaft sub-assembly.

      3. When the power steering link assembly moves during a collision (primary collision), the No. 2 intermediate shaft sub-assembly contracts, thus helping to reduce the amount that the steering column and the steering wheel protrude into the cabin.

      4. When an impact is transmitted to the steering wheel in a collision (secondary collision), the steering wheel helps absorb the impact. In addition, the breakaway bracket and the lower bracket separate, causing the entire steering column to move forward. At this time, the energy absorbing plate becomes deformed and the steering sliding with coupling yoke sub-assembly contracts to help absorb the impact of the secondary collision.
