The function of installing brackets for automobiles
Car mounts are divided into two types: one is the mobile phone mount used inside the car, and the other is the mechanical component of the vehicle body, with significant differences in function.
What is the use of the mobile phone mount inside the car?
- Fixing the phone: Keeping the phone stable on the air outlet or dashboard to avoid distraction when holding it.
- Facilitating navigation viewing: Easily viewing the route while driving to enhance driving safety.
- Saving space: Not occupying other functional areas of the center console, maintaining clear vision.
What is the function of the mechanical mounts on the vehicle body?
- Engine mount: Fixing the engine on the frame, absorbing and distributing engine vibrations, reducing shaking transmitted to the driver's cabin.
-保险杠支架： Supporting and fixing the bumper assembly， transmitting and distributing collision energy during a collision.
- Chassis mount： Supporting the installation of the engine and various components， forming the overall shape of the car and ensuring normal driving.
Encyclopedia
The "car mounts" commonly referred to in daily life mostly refer to the mobile phone mounts inside the car. When purchasing accessories， it is necessary to pay attention to the distinction.
"Malfunction of vehicle installation mounts" requires first clarifying the specific part：
- Engine mount (engine foot glue) malfunction manifests as severe shaking， jerking when accelerating (especially in low gears with large torque)， and audible rubber friction or metal impact sounds during acceleration； severe cases may involve engine displacement.
- Suspension/chassis mounts malfunction often accompanies vehicle tilting， abnormal noise during driving， or malfunction indicator lights； mobile phone/interior mounts are mostly loose or脱落.
The causes and risks of different parts vary greatly and cannot be treated interchangeably.
Core symptoms and rapid judgment：
- Engine mount damage： The vehicle body visibly shakes during idle or air conditioning operation， accelerating (especially in low gears with large torque) has a "shaking" jerk sensation， audible rubber friction or metal impact sounds during acceleration， and severe cases involve engine displacement.
- Suspension/chassis mount malfunction： Abnormal noise when crossing uneven terrain， vehicle resonance， shaking of the steering wheel； if accompanied by the "suspension fault indicator light" on， it may involve shock absorber， control arm mount fracture or sensor false alarm， and immediate inspection and repair are required.
- Mobile phone/interior mount problems： The suction cup fails (aging/oil contamination/temperature)； the latch loosens or the structure deforms， mainly affecting convenience， without direct driving safety risks.
- Pedal mount loosening： Shaking when stepping on the pedal， abnormal noise during low-speed bumps， mostly due to screws not being tightened diagonally or uneven force due to mud and sand on the chassis.
Treatment suggestions and steps：
- Emergency self-check： Stop the vehicle to check if the vehicle body is tilted， if the rubber of the mount is cracked or fallen off， and if the screws are missing； if the fault indicator light is on and the vehicle body is abnormal， do not drive at high speed or make sharp turns.
- Differentiate between severity： Parts related to the powertrain (engine mount) or the walking system (suspension mount) must be sent for repair； mobile phone mounts can be cleaned of the suction cup， heated to restore adhesion， or replaced with a different mounting method (such as air outlet/glue).
- Professional repair： Engine mounts require lifting the vehicle to replace the original factory parts and recalibrate； suspension mounts require diagnostic equipment to read codes and troubleshoot sensors or mechanical damage； do not attempt to weld or use strong glue to repair the load-bearing structural components. Notes for Attention
Long-term failure of the engine bracket can affect the surrounding pipelines, exhaust pipes and gearbox, accelerating component wear.
If the suspension fault indicator lights up due to air suspension leakage or spring breakage, continued driving may cause the chassis to touch the ground.
When repairing, priority should be given to original factory or well-known brand parts. Inferior brackets are prone to fatigue and fracture again.
