SHOCK ABSORBING MECHANISM
1. Primary impact
When the vehicle collides with something and there is a load
added to the shaft sub assembly from the gearbox, the shaft
sub assembly slides above the pipe sub assembly to absorb
the shock load. This prevents the steering column from
moving backwards during the impact.
2. Secondary impact
(1) When the driver falls against the developed air bag, the
tilt bracket(A) moves forwards by shearing the polyacetal
resin, causing the steering column assembly to move
forward.
