What is the working principle of continuously variable transmission?

1 Answers

The working principle of continuously variable transmission is: using a hydraulic torque converter to generate torques of different strengths, thereby transmitting torque to achieve continuously variable transmission. Types of continuously variable transmissions: 1. Mechanical: There are various forms, the most common being the cone-block metal V-belt type transmission, used in automobiles; 2. Hydraulic transmission type: used in engineering vehicles and agricultural machinery; 3. Electric type: used in electric vehicles. Starting devices for automotive continuously variable transmissions include: 1. Electromagnetic clutch type: large in mass and size, with low thermal load capacity; 2. Electronically controlled wet friction plate type: small in structural size, fast in response, and with low energy loss; 3. Hydraulic torque converter type: large starting torque, good hill-start performance, easy driving, good driving performance, and capable of reducing vibration and impact caused by uneven engine torque.

What Are the Models of Tubeless Tire Valves?

All tubeless tire valves have the same diameter, but the length and structure vary between large vehicles and small cars. Here is the relevant information: Tubeless Tires: Tubeless tires, also known as "low-pressure tires" or "inflatable tires," are pneumatic tires without an inner tube. They offer high elasticity, wear resistance, excellent traction, and heat dissipation. Note: Tubeless tires are made of high-quality rubber, providing good elasticity and flexibility, with a wide range of air pressure adaptability. Even at high pressure, they do not feel as rigid as conventional tires. Therefore, a pressure gauge must be used to check the tire pressure. Unless punctured, tubeless tires generally do not self-deflate. Thus, when inflating, always use a pressure gauge to check and maintain the specified pressure. Never rely on manual estimation, as with conventional tires, to decide whether to add air.

Will the insurance company fully compensate for a water-damaged car?

If you have purchased vehicle damage insurance and the no-deductible clause, the insurance will fully cover the claim in this situation. Here is the relevant information: Water-damaged car: A water-damaged car refers to a vehicle that has been submerged in water, typically meaning the engine and transmission have been soaked, with the water level exceeding the wheels and body seats, and the bottom components of the vehicle have been in prolonged contact with water. Such vehicles pose significant risks, as the electrical circuits are prone to short circuits and fires. Hazards: In reality, a repaired "water-damaged car" is like a "time bomb"—problems can arise at any moment, such as the engine suddenly stalling during high-speed driving, airbags failing to deploy in critical moments or deploying without reason. Although such cars may be cheap, they carry serious safety hazards in daily use, so consumers are advised not to purchase "water-damaged cars" just to save money.

What city does the license plate code Ji D belong to?

Ji D is the license plate code for Liaoyuan City in Jilin Province. The license plate codes for other regions in Jilin Province are as follows: Ji A is for Changchun City, Ji B is for Jilin City, Ji C is for Siping City, Ji E is for Tonghua City, Ji F is for Baishan City, Ji G is for Baicheng City, Ji H is for Yanbian Korean Autonomous Prefecture, Ji J is for Songyuan City, and Ji K is for Changbai Mountain. License plates, commonly referred to as vehicle plates, are panels affixed to the front and rear of vehicles, typically made of aluminum, sheet metal, plastic, or paper, and bear the vehicle's registration number, registration region, or other relevant information. License plates serve as a numbering and information registration system for vehicles, with the primary purpose of identifying the vehicle's region of registration and enabling the tracking of the vehicle's owner and registration details through the license plate.

Is it a violation to make a right turn from a straight lane? Will it be captured?

It is considered a violation to make a right turn from a straight lane, and it may be captured by electronic surveillance cameras. However, this depends on the specific setup of cameras at the intersection, as some intersections only monitor vehicles going straight from left or right lanes. Below is relevant information: Violation: A traffic violation (formerly known as a traffic offense, now referred to as a traffic infraction) generally refers to the act of motor vehicle drivers, non-motor vehicle riders, or pedestrians violating road traffic safety regulations, traffic management rules, or actions that affect traffic conditions. Additionally, a violation can also refer to handling matters contrary to standard procedures. Traffic Violations: Generally, there are two main types of traffic violation fines. One is an on-the-spot violation ticket, and the other is an electronic violation record. On-the-spot violation tickets are typically issued by traffic enforcement officers who provide evidence and issue a penalty decision.

What are the common failures of Nissan CVT?

Some common failure symptoms of Nissan CVT mainly include chain and sprocket damage, acceleration shudder, abnormal noises, and engine speed fluctuations. Failure causes: Steering wheel vibration is one of the most common vehicle issues in daily use. If it's only slight vibration, there should be no major problem as this is caused by engine resonance. If concerned, you can check whether the engine and transmission mounting brackets are secure, whether the support feet are reliable, whether the engine mounts are cracked, whether screws are loose, and whether the steering gear fixing screws are loose, etc. Inspection items: If the steering wheel vibrates during idle, then check whether the rubber bushings of the steering wheel transmission device are faulty and whether the bolts fixing the steering wheel transmission device are loose. Also check whether the steering wheel vibration is related to engine idle or steering gear. When the steering wheel is turned to full lock, vibration may occur sometimes accompanied by abnormal noises - this is mostly caused by steering gear pressure relief or air in the power steering fluid (mechanical type).

Do hybrid electric vehicles need to pay purchase tax?

Hybrid vehicles are exempt from vehicle purchase tax. According to the latest announcement from the Ministry of Finance, new energy vehicles are exempt from vehicle purchase tax. The types of new energy vehicles include pure electric vehicles, plug-in hybrid electric vehicles, and hydrogen fuel cell vehicles. It is advisable to consult in advance before purchasing. Hybrid vehicles are a combination of fuel engines and electric motors. The fuel engines use diesel or gasoline, and this type of vehicle belongs to the hybrid category. The electric motor is driven by batteries. These vehicles have excellent fuel efficiency and stronger driving performance. New energy vehicles use special license plates. Small and medium-sized vehicles use gradient green plates, while large vehicles use yellow-green dual-color plates. The version of the vehicle can be clearly distinguished from the license plate, thereby identifying the type of vehicle. Since new energy vehicles are not subject to traffic restrictions or license plate limitations, they can be easily distinguished.
