STEERING SHAFT AND COLUMN





The steering shaft and column, which informs the EPS-ECU of steering effort on the steering wheel, consist of a torque sensor and motors, etc. They are designed to improve safety, and has the following features:


IMPACT-ABSORBING MECHANISM



PRIMARY COLLISION



When a vehicle crash occurs and the intermediate shaft is loaded from the gearbox side, the intermediate shaft (A) is forced into the intermediate shaft (B) to absorb an impact load. By this, a rearward outthrusting of steering column is prevented.

SECONDARY COLLISION



When the driver’s body falls against the steering wheel via the deployed air bag, the column bracket moves forwards by deforming the rivet pin of the one-way capsule.
