STEERING SHAFT AND COLUMN







  • A collapsible intermediate shaft prevents the steering column from entering the passenger compartment during initial impact.
  • A system for energy absorption is provided by the breakaway steering column which has a one-way capsule.
  • A tilt steering mechanism enables the driver to obtain an optimum driving position.
    The tilt steering mechanism is essentially the same as a conventional one.

SHOCK ABSORBING MECHANISM



PRIMARY IMPACT




When the vehicle is in a collision and there is a force applied to the steering column assembly from the gearbox, the intermediate shaft is contracted to absorb the impact load. This prevents the steering column from moving backwards during the impact.

SECONDARY IMPACT



1.When the driver’s body falls against the deployed air bag, the tilt bracket (A) moves forward by crushing the one way capsule, causing the steering column assembly to move into the engine compartment.

2.In the fitted portions of the steering shaft and pipe, the polyacetal resin pieces of the pipe pressed onto the steering shaft are broken, and the impact load is absorbed as the pipe slides.
