The following are the differences between non-independent suspension and independent suspension: 1. Different advantages: Advantages of independent suspension: Lightweight, reduces the impact on the vehicle body, and improves the ground adhesion of the wheels; Advantages of non-independent suspension: Simple structure, low cost, high strength, easy maintenance, and minimal changes in front wheel alignment during driving. 2. Different disadvantages: Disadvantages of independent suspension: Complex structure, high cost, and inconvenient maintenance. Disadvantages of non-independent suspension: Poor comfort and handling stability. 3. Different categories: Independent suspension includes MacPherson strut independent suspension, multi-link independent suspension (four-link, five-link independent suspension), and double-wishbone independent suspension. Non-independent suspension includes torsion beam non-independent suspension (Watt's linkage suspension) and trailing arm non-independent suspension (semi-independent torsion beam suspension).

I've driven several cars and noticed a significant difference between non-independent and independent suspensions. Non-independent suspensions typically connect the wheels to a single axle, like the old Japanese car I drove with a torsion beam rear suspension. When going over speed bumps or rough roads, the body shakes noticeably, and if one wheel hits a bump, the other is affected too, making it quite uncomfortable. Independent suspensions allow each wheel to move independently. For example, the German SUV I drive now handles rough roads effortlessly, with each wheel able to absorb shocks individually, providing a smooth and quiet ride. However, independent suspensions are more expensive. For daily city driving, they might not be necessary, but their advantages are obvious on long trips or uneven terrain. Considering both comfort and price, I recommend choosing a non-independent suspension for city commuting to save money, while an independent suspension is more worthwhile for frequent travel.

What is used to affix temporary license plates?

Temporary license plates can be affixed using ordinary tape, 3M electrical insulating tape, or double-sided tape. A temporary motor vehicle license plate is a paper license plate issued by the vehicle management department of the public security authority, allowing the vehicle to be driven on the road temporarily, usually valid for no more than 30 days. Temporary license plates are categorized into: 1. Temporary plates for use within the administrative jurisdiction; 2. Temporary plates for use across administrative jurisdictions; 3. Temporary plates for testing purposes; 4. Temporary plates for special-type motor vehicles. Temporary license plates should be affixed to the lower left or right corner of the front windshield inside the vehicle, in a position that does not obstruct the driver's view, to ensure driving safety. Temporary license plates refer to temporary vehicle movement permits issued by the vehicle management department of the public security authority before the vehicle is officially registered due to the processing of certain procedures.

What is the reason why the dash cam cannot detect the memory card?

The reasons why the dash cam cannot detect the memory card: the memory card is damaged or the card slot for installing the memory card on the dash cam is damaged. When the dash cam cannot detect the memory card, you can try replacing it with another memory card. If it still cannot be detected, the card slot may be faulty; if a different memory card can be detected, then the issue lies with the original memory card causing the dash cam to fail to detect it. A dash cam is an instrument that records images, sounds, and other related information during vehicle travel. After installing a dash cam, it can record the entire driving process in video and audio, providing evidence for traffic accidents.

How long can you drive without engine oil before cylinder scuffing occurs?

If a car idles without engine oil, it can run for about half an hour; if driven without oil on the road, it can last at most 15-20 minutes. Hazards of running without oil: Prolonged operation without engine oil can cause irreversible damage to the engine and even lead to complete engine failure. Causes of cylinder scuffing: Due to the high-speed operation of the car engine, the friction between the pistons and other metal parts inside the engine can reach working temperatures of 400 to 600 degrees Celsius. Without oil lubrication, dry friction occurs between components, and without effective cooling, driving without engine oil for just a few minutes can cause phenomena like bearing seizure and cylinder scuffing due to excessive temperatures. A slightly longer duration can even lead to seized cylinders and complete engine failure.

How long does it take for a beginner to drive on the highway?

Beginners can drive alone on the highway after one year. According to relevant regulations, a new driver's license has a 12-month probationary period. During this probationary period, drivers are not allowed to drive on the highway alone and must be accompanied by someone with more than three years of driving experience. This is based on safety considerations, as it is quite dangerous for beginners to drive on the highway due to the high speeds and numerous precautions that need to be taken. Precautions for beginners driving on the highway: 1. Maintain a good mindset, stay calm, and avoid panic; 2. Prepare adequately by checking for tire cracks or bulges, ensuring lights are functioning properly, planning the route in advance, and confirming sufficient fuel; 3. Stay focused; 4. Pay attention to warning signs; 5. Avoid driving while fatigued; 6. Maintain proper following distance and signal in advance.

Does a broken car taillight cover need to be replaced entirely?

When a car taillight cover is broken, it generally needs to be replaced entirely. The function of the car taillight is to alert vehicles behind during nighttime driving, indicating the presence of a vehicle ahead and showing the positional relationship between the two vehicles. Taillights are installed on both sides at the rear of the car. Car lights and their functions are categorized as follows: 1. Headlights: Illuminate the road and objects ahead to ensure driving safety; 2. Position lights (width indicators): Indicate the width of the vehicle to alert oncoming and following vehicles; 3. Fog lights: Help oncoming and trailing vehicles detect the vehicle more easily; 4. Brake lights: Inform following vehicles to slow down or stop; 5. Low beams: Provide clear visibility of the road surface ahead; 6. High beams: Allow viewing of distant road conditions; 7. License plate lights: Illuminate the vehicle's license plate at night.
