What is the Principle of Car Movement?

For a car to move and travel at a certain speed, an external driving force must be applied along the direction of travel to overcome various resistances encountered during movement. The driving force is obtained by transmitting the engine's torque through the transmission system to the drive wheels. For a stationary car to start moving, it must overcome four types of resistances, as described below: 1. Rolling Resistance: Rolling resistance is primarily caused by the relative deformation between the tires and the ground due to the car's weight. The magnitude of this resistance is directly related to the car's total weight, tire structure and pressure, as well as the condition and grade of the road surface. 2. Air Resistance: Air resistance arises from the friction between the car's surface and the air during movement, as well as the pressure of the oncoming airflow at the front of the car and the vacuum created by the air vortex at the rear. The magnitude of this resistance is influenced by the car's frontal projected area, aerodynamic shape, and speed, with speed having the greatest impact. 3. Uphill Resistance: Uphill resistance depends on the car's total weight and the steepness of the slope. The greater the car's total weight and the steeper the road, the higher the uphill resistance, and vice versa. Conversely, downhill slopes can become a driving force for the car. 4. Inertial Resistance: Inertial resistance only occurs during the car's variable-speed motion. According to the principle of inertia, when the car accelerates, the inertial resistance acts opposite to the direction of travel. When the car decelerates, the stored kinetic energy attempts to maintain the original speed, causing the car to coast forward.

At What Extent of Wheel Rim Damage Should It Be Replaced?

Here is the relevant information about when to replace a wheel rim: 1. A piece is missing from the outermost edge of the wheel rim: This may affect the airtightness. Even if there is no immediate air leakage, the strength to maintain airtightness is insufficient, which could lead to a tire blowout under extreme conditions. Car tires do not have inner tubes, only outer tires. After inflating the tire, the tire expands outward, and the edge just fits into the rim edge, relying on the tight fit between the tire and the rim to maintain airtightness. 2. The edge of the wheel rim is not chipped but deformed: Regardless of how the wheel rim is damaged, whether it needs to be replaced depends on the location of the damage. If the edge is damaged, it must be replaced; if the edge is not damaged, it does not need to be replaced. A wheel rim is not cheap and is significantly more expensive than a tire, so it should be repaired if possible and replaced if it cannot be repaired. 3. The wheel rim is subjected to significant external force, causing deformation: Minor deformations are not visible to the naked eye and can only be detected through dynamic balancing. When the wheel rotates on the balancing machine, if it wobbles severely from side to side, and the balancing values show a significant deviation from the standard, sometimes differing by more than 100 grams or even 200 grams, this is caused by wheel deformation. Adding balancing weights usually cannot achieve balance, so it is best to replace the rim. Although minor wheel rim deformation will not cause a blowout, it can lead to severe steering wheel vibration at high speeds, which is dangerous and provides a poor driving experience.

What is the tire size of the GS4?

The GS4 has two tire sizes: 225/60R17 and 225/55R18. In 225/60R17, the first number 225 represents the tire width of 225MM, 60 indicates the aspect ratio of the tire section is 60%, meaning the section height is 60% of the width, 17 stands for the rim diameter of 17 inches, and the letter "R" in the middle denotes a radial tire. In 225/55R18, the first number 225 represents the tire width of 225MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, 18 stands for the rim diameter of 18 inches, and the letter "R" in the middle denotes a radial tire. The GS4 tires feature a five-spoke wheel rim design, giving a more powerful appearance, and are matched with Giti Comfort-F50 tires. The spare tire is non-full size. If you want to replace the tires yourself, you can follow these steps: Take out the spare tire and jack, place the jack under the vehicle frame near the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car, the jack should be positioned under the vehicle, check and ensure the jack is at a right angle to the ground; Remove the hubcap, loosen the nuts counterclockwise, do not fully loosen them, just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts turn, not the tire; Turn the nuts counterclockwise until they are loose, repeat this step for all lug nuts, then completely remove the nuts; Place the new tire on the hub, carefully align the tire rim with the wheel bolts, install the lug nuts, and tighten them by hand until all nuts are snug. At this point, the tire replacement is complete. In addition to the model, the tire also has the following common data marked on it: Tire cord material: Indicated by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under specified conditions. Letters A to Z represent the certified speed ratings of tires from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Indicates the rim specification compatible with the tire. For practical use, such as "Standard rim 5.00F".

What are the symptoms of a broken gearbox?

The symptoms of a broken gearbox include: inability to engage gears, failure to move when in D gear, jerking, etc. The gearbox is what is commonly referred to as the transmission. Transmissions are divided into manual transmissions and automatic transmissions. Manual transmissions generally do not experience many faults; automatic transmissions include torque converter transmissions, CVT transmissions, dual-clutch transmissions, and AMT transmissions. Manual transmissions mainly consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque changes through hydraulic power transmission and gear combinations.

What is power steering oil?

Power steering oil is a special fluid used in the car's power steering pump. Through hydraulic action, it can make the steering wheel lighter, similar to automatic transmission fluid, brake fluid, and shock absorber fluid. To prevent the power steering oil from becoming dirty or deteriorating, it should be replaced every 2 years or 30,000 kilometers. Precautions for using power steering oil include: 1. Power steering oil contains carcinogenic substances; if it comes into contact with the skin, it should be washed off immediately. 2. For cars equipped with hydraulic power steering systems, avoid holding the steering wheel at full lock for extended periods, as this can burn out the power steering pump over time.

What are the reasons for the failure of car auto-locking?

Car auto-locking failure is caused by poor wire contact or door lock damage, and it may also be a program malfunction issue, requiring inspection and repair at a service center. The purpose of the auto-locking function is theft prevention, allowing the doors to lock quickly after driving to prevent door-pull robberies during traffic jams or at red lights, providing a certain level of security. The car auto-locking function, also known as speed-sensing auto-lock, is an electronic device that automatically presses the lock button on the door when the vehicle speed reaches a computer-set value, preventing accidental door opening. The set value is generally factory-set, usually between 10 to 20 kilometers per hour.
