The function of the horns at the front of a car
Steering Knuckle, also known as "sheep's horn", is one of the important parts in the steering axle of a car, which can enable the car to drive stably and sensitively transmit the driving direction.
The function of the steering knuckle is to transfer and bear the load at the front of the vehicle, support and drive the front wheels to rotate around the main pin, thereby steering the vehicle. When a car is in motion, it is subjected to variable impact loads, so it is required to have very high strength
Damage to the front knuckle (steering knuckle) of a car can lead to the following problems
Abnormal driving
Youdaoplaceholder0 Tire uneven wear : Inaccurate four-wheel alignment causes abnormal tire wear (commonly known as "tire wear"), accelerating tire aging.
Youdaoplaceholder0 direction deviation : The steering accuracy of the front wheels decreases, and the vehicle is prone to deviate from the predetermined trajectory.
Youdaoplaceholder0 Heavy steering : The resistance of the steering system increases, and the steering wheel feels heavy when operated.
Mechanical failure
Youdaoplaceholder0 Abnormal noise and vibration : You may hear a "buzzing" sound or abnormal vibration of the steering wheel while driving.
Youdaoplaceholder0 Brake shake : The steering wheel or the vehicle body shakes when braking.
Youdaoplaceholder0 suspension damage : Long-term lack of maintenance may lead to a decline in the overall performance of the suspension system.
Basis for judgment
Youdaoplaceholder0 Visual inspection : Deformation or oxidation and peeling of sheep 's horns can cause abnormal appearance.
Youdaoplaceholder0 Mechanical testing : After removing the steering bolt, observe whether the hole position is deformed or rusted.
Youdaoplaceholder0 Abnormal four-wheel alignment data : The typical features are the main pin rearward tilt and the front wheel outward tilt Angle being inaccurate.
It is recommended that timely maintenance be carried out upon discovering the above symptoms to avoid greater losses.
Youdaoplaceholder0 Rusting of the front horns (steering knuckles) of a car is a normal phenomenon in most cases, mainly caused by environmental factors. However, it is necessary to determine whether it is abnormal based on the degree of rusting : slight surface rusting usually does not require concern, while severe rusting may affect safety and needs to be dealt with promptly.
The basis for judging the normality of rusting is
The front knuckle of a car (also known as the steering knuckle) is a core component of the steering axle, responsible for the front load and steering functions. It is usually made of cast iron or steel. Whether its rusting is normal needs to be analyzed comprehensively based on the following factors:
Youdaoplaceholder0 under normal circumstances :
Minor surface rust (such as floating rust) is commonly seen in long-term exposure to damp, rainy or salt spray environments. It is a natural oxidation process of metals and does not affect structural strength.
Minor rust on a new car in the short term (such as due to thin paint at the weld points) is usually not a quality issue but is related to the material and manufacturing process.
Youdaoplaceholder0 abnormal situation :
Overall rusting or deep rusting (large rust area, uneven metal) may be caused by insufficient rust prevention measures, long-term damp environment or metal fatigue, and should be taken seriously.
Severe rust on a new car may indicate factory defects or improper maintenance.
Youdaoplaceholder0 Effects of rusting and treatment suggestions
The degree of rusting is directly related to safety risks and maintenance measures
Youdaoplaceholder0 potential impact :
Slight rust: Generally does not affect performance, but may accelerate the aging of components.
Severe rust: It causes inflexible steering, shaking, noise, and in extreme cases, it may break, leading to out-of-control accidents.
Youdaoplaceholder0 handling and maintenance of :
Minor rust: After cleaning, grind off the rust and apply anti-rust paint or anti-rust oil.
Severe rust: Professional repair shop is required for inspection. If necessary, replace the steering knuckle.
Preventive measures: Regularly inspect the chassis, avoid long-term parking in damp environments, and consider spraying chassis armor.
Youdaoplaceholder0 user notes
Youdaoplaceholder0 Self-inspection method : Observe the area of rust (small areas are normal), touch depth (light rust can be dealt with by yourself), and test the flexibility of turning (jamming requires maintenance).
Youdaoplaceholder0 Priority action : If rust is accompanied by abnormal steering noise or poor handling, it should be sent for inspection immediately to avoid potential safety hazards.
