Is It Normal for a Car Steering Knuckle to Rust?
1 Answers
If there is slight rust under the steering shaft, it is a normal phenomenon. The steering column is generally not covered with paint for anti-oxidation protection, so after using the steering column for a period of time, a layer of rust will appear on it, which can be dealt with accordingly. Extended content: 1. Principle: The steering shaft is a transmission component connecting the steering wheel and the steering gear. The steering column tube is fixed to the car body, and the steering shaft passes through the steering column tube, supported by bearings and bushings inside the column tube. During a collision, the steering column tube and steering shaft at the front of the car move backward toward the driver's chest, while the driver, affected by inertia, moves toward the steering wheel. Part of the energy is absorbed by the restraint system, and the other part is transmitted to the steering wheel and steering column tube. A good car steering system should ensure that the driver is minimally injured in the event of a collision. 2. Function: The application of energy-absorbing steering columns in car steering systems plays a significant role in energy absorption. The role of the energy-absorbing steering column during a collision demonstrates that this structure reduces the rearward movement of the steering wheel during a frontal collision, decreases the degree of secondary injuries to occupants, and improves the passive safety performance of the car.
