What is Car Suspension?

1 Answers

07/29/25 8:55pm

Car suspension refers to the entire support system composed of springs and shock absorbers between the body and the tires. The main function of the suspension is to transmit all forces and moments acting between the wheels and the body, such as supporting force, braking force, and driving force, while mitigating the impact loads transmitted from uneven road surfaces to the body, dampening the resulting vibrations, ensuring passenger comfort, and reducing the dynamic loads on cargo and the vehicle itself. The suspension elastically connects the frame to the wheels and is related to various performance aspects of the vehicle, making it one of the three most important assemblies in a car. Structurally, car suspension consists of simple components such as rods, tubes, and springs, but it is a very challenging assembly to perfect. This is because the suspension must meet both the vehicle's handling stability requirements and comfort requirements, which are often contradictory to each other.

Where is the cigarette lighter in the Roewe RX5 Plus?

The cigarette lighter in the Roewe RX5 Plus is located under the left dashboard cover. Here are the specific details about the car cigarette lighter: 1. Heating: The voltage of the car cigarette lighter is usually 12V, 24V, or 48V, with 12V being the most common. The central elastic head of the lighter is the positive pole, while the side clips are the negative poles. The car cigarette lighter requires about 10 seconds to heat up, and it will not pop out until the heating process is complete. 2. Function: The car cigarette lighter is similar to a multi-socket power source for household use, designed to allow car owners to smoke. 3. Aging: If the cigarette lighter is frequently inserted or removed, it can accelerate aging and reduce its lifespan.

What Causes a Car to Shake After Starting?

The reasons for a car shaking after starting are: 1. Severe carbon deposits in the engine cylinders, which can cause spark plug blockage and valve blockage; 2. Unstable oil pressure, which easily leads to unstable concentration of the air-fuel mixture; 3. Aging engine mounts; 4. Issues with the ignition coil or the spark plugs failing to fire for some reason. If the car shakes when first started but stops shaking after the engine warms up, this could be due to the lubrication system not fully lubricating during a cold start, causing rough operation, or the engine not yet reaching the appropriate operating temperature, resulting in incomplete fuel combustion and knocking. If the car shakes upon starting, it is recommended that the owner promptly take it to a 4S shop for inspection and repair. Do not take it lightly; it is important to identify the source of the shaking promptly, as it could otherwise lead to more significant issues.

How to distinguish between dry and wet Volkswagen dual-clutch transmissions?

To distinguish between dry and wet Volkswagen dual-clutch transmissions, you can check the car's rear emblem. If the rear of the Volkswagen car is labeled with 230 or 280, it uses a dry dual-clutch transmission; if it is labeled with 330 or 380, it uses a wet dual-clutch transmission. The clutch plates in a dry dual-clutch transmission are not immersed in transmission oil, whereas those in a wet dual-clutch transmission are immersed in transmission oil. Taking the Volkswagen Magotan as an example, the car has a length, width, and height of 4866mm, 1832mm, and 1464mm respectively, with a wheelbase of 2812mm. The extensive use of chrome accents and dual horizontal lines on the front face exudes a noble and distinguished kingly temperament.

How to Reverse Park a Car?

The method for reverse parking is: 1. Park your car in front of the second parking space next to the target spot, aligning your left rearview mirror with the center of the second parking space while maintaining a distance of approximately 1.5 meters; 2. Turn the steering wheel fully to the right, shift into reverse gear, and let the car slowly back up; 3. When the car body is basically parallel with the parking space, straighten the steering wheel and reverse into the space. Precautions for reverse parking include: 1. Before reversing, check the situation behind the car, plan the reversing route, and ensure the front of the car won't hit any obstacles during the process; 2. Try to choose to reverse from the left side; 3. Point the front of the car towards an open area with room for maneuvering to better observe moving people or vehicles; 4. Gently press the accelerator to control the speed; 5. Ensure the safety behind the car and pay attention to the distance between obstacles and the car body.

What to Do If the Production Dates of the Front and Rear Glass of a New Car Are Inconsistent?

It is normal for the production dates of the front and rear glass of a new car to be inconsistent, as there can indeed be discrepancies between the glass production dates and the vehicle during assembly. This is because it is impossible for all the glass to be produced at the exact same time, and it has no bearing on whether the car itself has any issues. If there are quality problems with the glass, such as cracking, the inconsistent production dates can serve as valid evidence of glass quality issues, but they cannot prove that the car itself has any problems. Different components in various locations are manufactured separately by the automaker's suppliers and then assembled into a new car by the manufacturer. It is possible for different parts of the vehicle to have different manufacturing dates, and this is nothing to worry about. Such inconsistencies do not indicate that the car has been in an accident or has other issues.

What to Do When a Tire Blows Out While Driving?

Solutions for a tire blowout while driving: 1. Front tire blowout: Firmly grip the steering wheel to adjust the car's direction, avoid repeatedly jerking the steering wheel or slamming on the brakes. Wait for the vehicle speed to gradually decrease before gently steering; 2. Rear tire blowout: Hold the steering wheel steady and lightly press the brake pedal to shift the car's center of gravity forward, allowing the intact front tires to bear more weight and reduce pressure on the blown-out rear tire; 3. Place a warning triangle 50 to 150 meters behind the vehicle. Daily tire maintenance: 1. Regularly check if the tread wear indicators are reached; 2. Check tire pressure at least every two months; 3. Frequently inspect tires for damage, such as punctures or cuts, and repair or replace damaged tires promptly; 4. Remove stones from the tread grooves to prevent deformation of the tire crown; 5. Regularly perform four-wheel alignment checks on the vehicle and correct any misalignment immediately if detected.
