What are the types of continuously variable transmissions?

Types of continuously variable transmissions: 1. Mechanical type: There are various forms, with the common one being the cone-block metal V-belt drive, used in automobiles; 2. Hydraulic transmission type: Used in engineering vehicles and agricultural machinery; 3. Electric type: Used in electric vehicles. The starting devices for automotive continuously variable transmissions come in the following three forms: 1. Electromagnetic clutch type: Large in mass and size, with low thermal load capacity; 2. Electronically controlled wet friction plate type: Compact in structure, fast response, and low energy loss; 3. Hydraulic torque converter type: High starting torque, excellent hill-start performance, easy driving, good creep performance, and capable of reducing vibrations and shocks caused by uneven engine torque.

How Many Degrees Should the Steering Wheel Be Turned for Lane Changing?

When changing lanes, the steering wheel should be turned between 3 to 10 degrees. While driving on the road, it is important not to turn the steering wheel abruptly in emergency situations, as this can easily lead to traffic accidents. Generally, slight adjustments are sufficient. The steering wheel is typically composed of a skeleton and foam, forming a simple structure. Modern steering wheels often come with various switch settings, such as buttons for answering phone calls, accelerating or decelerating the car, and cruise control. When driving on bumpy roads, it is essential to hold the steering wheel firmly with both hands to prevent loss of control. Misalignment of the steering wheel may be related to the tire pressure, the degree of tire wear, wear and tear on the car's chassis components, and the vehicle's four-wheel alignment. Adjusting the tire pressure and then measuring the four-wheel alignment values may be necessary.

What does it mean when the transmission is not shifted into P gear?

Transmission not shifted into P gear means the gear lever is not in the P position, and such a prompt will appear when stopping and opening the door, which is a safety measure. There are two things to note when parking an automatic transmission car: first, do not shift into P gear while the engine is running, and second, apply the handbrake first, then shift into P gear, so that the force acts on the handbrake rather than the transmission. The correct parking method: 1. When the car stops, first slow down, press the brake, and shift into N gear. The reason for not directly shifting to P gear and then turning off the engine is to prevent the transmission from passing through R gear while the engine is running, thereby reducing one impact; 2. Turn off the engine. At this time, the power will not be cut off because the P gear is not engaged, and the key cannot be removed; 3. Tighten the handbrake and release the foot brake.

What Are the Precautions for Driving in the Rain?

Precautions for driving in the rain include ensuring the vehicle's mechanical systems are functioning properly and reducing speed; promptly turning on fog lights, and continuously monitoring the wipers, brake system, headlights, taillights, and tire pressure. If the rainfall is heavy and visibility is less than 100 meters, all lights should be turned on, and if possible, pull over to the side of the road. If stopping is not an option, proceed at a low speed while avoiding acceleration and braking, and strictly avoid changing lanes. Resume normal driving only when the rain eases. Rain can easily lead to water accumulation, especially in areas like underpasses, where standing water can cause significant damage to the vehicle. It is advisable to avoid severely waterlogged sections of the road whenever possible. If driving through water is unavoidable, check the water depth beforehand and proceed only if it is safe to do so.

When Does a Vehicle Start to Be Considered as Scrap?

The scrap age of a vehicle varies depending on the type: commercial vehicles, motorcycles, full trailers, semi-trailers for hazardous goods transportation, and other motor vehicles are calculated based on their service life. However, vehicles that reach a certain mileage are also guided to be scrapped. Small and micro non-commercial passenger vehicles, as well as large non-commercial cars, have no service life limit and can be used as long as they pass the annual inspection. The so-called scrap vehicle refers to a vehicle that has reached a certain service life or has been severely damaged or has poor technical conditions due to other reasons, cannot be repaired, and is compulsorily scrapped according to government regulations. Due to the poor mechanical performance and aging parts of scrap vehicles, coupled with drivers who, in order to carry passengers, haul goods, or make money, arbitrarily reassemble, modify, or damage the balance and stability of the vehicle structure, if the vehicle continues to be used when its technical condition does not meet the requirements, it will lead to various failures, directly affecting driving safety and inducing traffic accidents.

How many points are deducted for not yielding to a school bus?

Not yielding to a school bus results in a 6-point deduction. The correct method to yield when encountering a stopped school bus: On a road with only one lane in the same direction: When a school bus stops on a road with only one lane in the same direction, vehicles behind must stop and wait, and are not allowed to overtake. On a road with two or more lanes in the same direction: When a school bus stops on a road with two or more lanes in the same direction, vehicles in the same lane behind and in adjacent lanes must stop and wait, while vehicles in other lanes should slow down and pass. When riding a school bus, always fasten your seatbelt; otherwise, you may suffer collision injuries during braking. Eating or drinking is prohibited while the school bus is in motion to avoid food or beverages entering the respiratory tract during sudden braking or accidental collisions, which could cause harm or endanger life safety.
