What is a Steering Column?
2 Answers
Steering column is the component that connects the steering wheel and the steering gear in the steering system. Through the steering column, the driver transmits torque to the steering gear to achieve steering. Common types of steering columns include hydraulic power steering column, electro-hydraulic power steering column, and electric power steering column, each with different systems. The steering column is a device located on the car's steering wheel, allowing the driver to control the direction. If the steering column is damaged, the vehicle will be difficult to control, and steering deviations are likely to occur. Therefore, any issues with the vehicle should be inspected and repaired immediately. The energy-absorbing steering column reduces the rearward displacement of the steering wheel during frontal collisions, minimizing secondary injuries to occupants and improving the vehicle's passive safety performance.
As a seasoned mechanic who works on cars all day, the steering column is essentially the skeleton of a car's steering wheel. It connects the steering wheel to the steering gear system, transmitting your steering inputs to the wheels. This component must be sturdy and reliable—no room for carelessness. Typically made of steel, it includes bushings and universal joints to prevent breakage. I've seen many cases where an aging steering column causes steering wheel looseness, creaking noises during turns, or even compromised handling safety. If your steering wheel shakes excessively or makes unusual noises while driving, it could signal a steering column issue, requiring prompt inspection and part replacement—otherwise, it could lead to serious accidents at high speeds. During maintenance, ensure proper lubrication of the bearings and keep dust out to extend its lifespan. In modern cars, the steering column is also linked to the airbag system, designed to collapse during a collision to protect the driver—showing increasingly user-friendly engineering.
