What are the functions and uses of the car ingot beam
The car frame (also known as the subframe) is a core component of the chassis. Its main functions are to support the engine and transmission, connect the suspension system, block vibration and noise , and enhance driving stability and comfort. The following is a detailed description of its function and practical use:
Core function: Make cars more stable and quieter
The Yuanbao beam is like the "skeleton" of a car, undertaking the following key functions:
Youdaoplaceholder0 Support powertrain : Firmly secure the engine and transmission, reduce shaking during driving, and ensure smoother power output.
Youdaoplaceholder0 connection suspension system : By installing components such as control arms and stabilizer bars, the impact force on the road surface is dispersed, and the handling when cornering and on bumpy roads is improved.
Youdaoplaceholder0 Block vibration and noise : Use rubber bushings to absorb the vibration from the engine and the road surface, reducing noise transmission into the cabin by over 60%, making driving quieter.
Youdaoplaceholder0 Enhance chassis rigidity : The frame structure improves the torsional resistance of the vehicle body (about 15%-20%), reduces roll when taking high-speed turns, and avoids a loose feeling.
Youdaoplaceholder0 Collision protection : disperses the impact force in an accident (such as a 25% offset collision), prioritizes the impact, and protects key components such as the oil pan and engine.
Practical application: Value in different scenarios
Depending on the vehicle model and road conditions, the Yuanbao beam plays different roles:
Youdaoplaceholder0 Daily driving : Reduces bumps and noise, enhances comfort, and is especially suitable for urban commuting.
Youdaoplaceholder0 Complex road conditions : On sandy and gravel or off-road surfaces, enhance the rigidity of the chassis, prevent suspension deformation, and extend the lifespan of parts.
Youdaoplaceholder0 Safety protection : Absorbs energy in the event of a collision, reducing the risk of injury to occupants. The full-frame design performs even better.
Youdaoplaceholder0 Performance optimization : Luxury cars and sports models use it to enhance handling. For instance, the BMW M3 achieves precise cornering through a full-frame yuanbao beam.
Tips for selection and maintenance
Youdaoplaceholder0 Type selection : Full-frame (four-sided closed) has high strength but high cost, suitable for performance cars; The semi-section type (simple structure) has a low cost and is more commonly seen in family cars.
Youdaoplaceholder0 Pay attention to maintenance : The rubber bushing should be inspected every 40,000 to 60,000 kilometers. Aging can cause abnormal noise or reduced handling.
When the jade beam of a vehicle is damaged, the following symptoms may be manifested:
The driving stability of the vehicle will be affected, and the steering wheel may experience abnormal shaking. This could be due to the damage of the ingot beam causing a change in the vehicle's posture.
During driving, you may hear abnormal noises. This is because the ingot beam connects the vehicle body and the suspension system, and its damage may affect the normal operation of the suspension system.
The acceleration performance of the vehicle may decline, which is due to the deformation of the body caused by the failure of the Yuanbao beam, further affecting the stability of the vehicle.
The braking system may be affected, resulting in weakened braking effect or complete failure, which will pose a threat to driving safety.
The ride comfort may be reduced as the damage to the Yuanbao beam may cause problems with the suspension system. If you find that your vehicle shows the above symptoms, it is recommended that you check the condition of the Yuanbao beam in time. If necessary, it should be repaired or replaced. At the same time, regularly inspecting and maintaining the vehicle's Yuanbao beam is an important measure to ensure driving safety.
