Here is an introduction to the types of automotive suspension systems: 1. Non-independent suspension system: The structural feature of a non-independent suspension system is that both wheels are connected by an integral frame, and the wheels, along with the axle, are suspended under the frame or body via an elastic suspension system. Non-independent suspension systems offer advantages such as simple structure, low cost, high strength, easy maintenance, and minimal changes in front-wheel alignment during driving. 2. Independent suspension system: In an independent suspension system, each wheel is individually suspended under the frame or body via an elastic suspension system. Its advantages include: lightweight, reducing the impact on the body, and improving the ground adhesion of the wheels; the use of softer springs with lower stiffness enhances ride comfort; and it allows for lowering the engine position. (1) MacPherson suspension system: The MacPherson suspension system also involves wheels sliding along the kingpin, but it differs from the candle suspension system in that the kingpin can swing. The MacPherson suspension system is a combination of the swing-arm and candle suspension systems. (2) Transverse arm suspension system: The transverse arm suspension system refers to an independent suspension system where the wheels swing within the transverse plane of the vehicle. It is further divided into double-wishbone and single-wishbone suspension systems based on the number of transverse arms. (3) Multi-link suspension system: The multi-link suspension system consists of (3–5) rods combined to control the positional changes of the wheels. It allows the wheels to swing around an axis at a certain angle to the vehicle's longitudinal axis, serving as a compromise between transverse and longitudinal arm suspension systems. (4) Leaf spring non-independent suspension system: Leaf springs are used as the elastic elements in non-independent suspensions. Since they also function as guiding mechanisms, the suspension system is greatly simplified. This type of suspension is widely used in the front and rear suspensions of trucks. (5) Active suspension system: The active suspension system is a new type of suspension system developed in recent decades and controlled by a computer. It integrates knowledge from mechanics and electronics and is a relatively complex high-tech device.

Will crossing the line on the highway definitely be captured by cameras?

Not necessarily. There are fixed traffic routes where lane changes and crossing the line are prohibited and monitored, but not all instances will be captured. When changing lanes, pay attention to the following: Do not change lanes in solid line sections, do not cross multiple lanes at once, do not start turning before the vehicle has completely passed the stop line, and do not proceed against the signal after passing the stop line. Relevant regulations: Article 51 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates: After entering a guiding lane, motor vehicles must proceed through the intersection in the direction indicated by the guiding arrows and must not change lanes or direction. If a vehicle changes lanes after entering a guiding lane, it constitutes the act of "crossing the white line," and changing lanes by crossing a solid line is penalized as "failing to follow traffic signal instructions."

Can the emergency lane be temporarily opened for driving?

Emergency lanes cannot be temporarily opened for driving. Purpose of emergency lanes: Emergency lanes are specially designated for prevention and emergency purposes. Under normal circumstances, they are only for vehicles such as medical ambulances, police vehicles on official duty, fire rescue vehicles, and engineering emergency rescue vehicles. Temporary opening of emergency lanes: In the event of an emergency, the emergency lane is opened for the above-mentioned vehicles to pass through, so that these emergency vehicles can quickly and smoothly reach the scene of the incident. Therefore, it is best for civilian vehicles not to drive or stop on the emergency lane to avoid delaying rescue, causing inconvenience to others, and posing safety risks to themselves.

Can vehicle inspection be done during National Day holiday?

According to the national statutory holidays, there is a unified holiday. The vehicle management office will not be open, so annual inspection cannot be conducted. Introduction to annual inspection: Vehicle annual inspection refers to a mandatory test for all vehicles that have obtained official license plates and registration certificates, equivalent to an annual physical examination for vehicles according to the "Technical Conditions for Motor Vehicle Operation Safety". Relevant policies for annual inspection: There are relevant regulations in documents such as the "Implementation Regulations of the Road Traffic Safety Law" regarding vehicle annual inspections. Some preparatory work is required before the inspection (such as knowing relevant information, online appointment, procedures, vehicle precautions, etc.) to ensure normal and smooth passage. There are initial and regular annual inspections, as well as some related policies.

What brand is LANVIGATOR tires?

LANVIGATOR is a tire brand under Lavit Tires. Lavit Tires is a tire brand produced by Shandong Haohua Tire Co., Ltd. The Lavit tire product line includes: CATCHGREGP100, CATCHPOWER (PCR), COMFORT, MILEMAX, TOURINGMAX, CATCHPOWER (SUV), PERFORMAX, PRIMETOUR, CATCHFORSA/T, CATCHFORSM/T, CATCHSNOW, SNOWPOWER, etc. Shandong Haohua Tire Co., Ltd. is a professional tire manufacturer. The company is one of the larger private tire manufacturers in China. The company has two all-steel factories and one semi-steel factory, with four brands under different product lines: LANVIGATOR, APLUS, COMPASAL, and ROYALBLACK. Each brand covers more than 700 models, including TBR, LTR, A/T, H/T, M/T, VAN tire, PCR tire, winter tires, and all-season tires. The characteristics of Lavit tires: excellent handling performance and steering stability. The unique shoulder design prevents tire side slipping, providing outstanding handling and steering performance. The excellent formula design enhances tire performance and helps extend mileage. The continuous shoulder tread pattern effectively avoids abnormal wear and reduces noise generated by the shoulder tread. The advanced structural design can effectively prevent abnormal stability during high-speed driving. Methods for maintaining Lavit tires: Increase awareness of tire safety and inspect tires regularly. Regularly correct wheel balance; unbalanced wheels can cause high-frequency oscillations during high-speed driving, leading to uneven tire wear. Perform regular tire rotation. To ensure even wear on all tires of the same vehicle, rotate the tires every 5,000 kilometers. In daily use of Lavit tires, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves gradually become shallow. If the tread is worn flat, it will lose its drainage and anti-skid functions, significantly reducing the vehicle's performance. Small cracks can be potential hazards for tire blowouts at high speeds. Additionally, promptly remove pebbles from the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park the vehicle near or in contact with petroleum products, acids, or other materials related to rubber deterioration. After parking, the driver should not turn the steering wheel, as this operation will accelerate tire wear. Do not splash water to cool down. In hot weather or during high-speed driving, tires are prone to overheating, and tire pressure increases. In such cases, stop to allow the tires to cool naturally. Never release air to reduce pressure or splash water to cool down, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent and sudden braking to prevent accelerated tread wear caused by dragging between the tires and the ground.

Why is there no air coming from the car air conditioner?

Reasons for no air coming from the car air conditioner: blower failure, clogged air filter. Blower failure: The car blower is a crucial component for air output in the car air conditioning system. If the air conditioning compressor fails during operation, the car air conditioner will definitely not blow air. Overheating damage to the internal coils of the blower or capacitor failure are significant causes of blower malfunction. You can turn the car air conditioner to its maximum setting and listen for the blower's sound. If the blower is confirmed to be faulty, it needs to be addressed at a 4S shop as it's difficult to resolve on your own. Clogged air filter: The air filter is a common and major reason for no air output from the air conditioner. During operation, the car air conditioner absorbs many impurities from the air, leading to a clogged air filter. If there's no air coming from the air conditioner, you can remove the air filter to check if it's clean. If the air filter is too dirty, it needs to be replaced promptly. You can go to a 4S shop or a repair shop, or you can replace it yourself.
