STEERING COLUMN SYSTEM


  1. CONSTRUCTION


    1. Manual Tilt and Telescopic Mechanism


      1. The manual tilt and telescopic mechanism allows adjustment of the steering wheel position in the vertical and longitudinal (extending and retracting) directions through lever operation. This provides the driver with the most comfortable driving position.

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

      3. The tilt adjustment range is 30 mm (1.18 in.).

      4. The telescopic adjustment range is 40 mm (1.57 in.).

    2. Energy Absorbing Mechanism


      1. The energy absorbing mechanism mainly consists of a breakaway bracket, main shaft, column tube and steering intermediate shaft.

      2. The steering column assembly is mounted on the instrument panel reinforcement via the breakaway bracket. The steering column assembly and the steering gear assembly are connected with a contractile steering intermediate shaft.

      3. When the steering gear moves during a collision (primary collision), the steering intermediate shaft contracts, thus helping reduce the possibility of the steering column and the steering wheel protruding into the cabin.

      4. When a collision impact is transmitted to the steering wheel (secondary collision), the steering wheel and the driver's airbag help absorb the impact. In addition, the breakaway bracket separates, and the main shaft and column tube contracts. At this time, the friction resistance of the sliding portion absorbs the energy. This sequential energy absorbing mechanism helps absorb the impact of the secondary collision.
