The three major types of transmissions are AT, CVT, and dual-clutch transmissions. Below are the relevant introductions: AT Transmission: Hydraulic automatic transmissions achieve automatic shifting through a combination of hydraulic transmission and planetary gears. They generally consist of components such as a torque converter, planetary gear mechanism, shift execution mechanism, shift control system, and shift operation mechanism. CVT Transmission: Continuously Variable Transmissions differ from traditional automatic transmissions in that they do not have a gearbox composed of a set of gears, meaning they lack interlocking gears. The most common type of CVT operates on an ingeniously designed pulley system that provides infinite variability between the highest and lowest gears without discrete steps or shifts. Dual-Clutch Transmission: Dual-clutch transmissions combine the advantages of manual and automatic transmissions. Instead of using a torque converter, they employ two sets of clutches that alternate to achieve seamless shifting.

What is the reason for the car key not turning?

The reasons why the car key cannot be turned are: Steering wheel lock: The owner should gently turn the key with the right hand while lightly rotating the steering wheel with the left hand, and the steering wheel will naturally unlock, allowing the car to start smoothly; Another reason is that the key is not inserted properly, the lock body is damaged, or the gear is not in neutral. A car remote key refers to a key that can remotely open and lock the door without inserting the key into the keyhole, regardless of day or night, without the need to locate the keyhole, allowing for convenient remote locking and unlocking. A weak radio wave is emitted from the owner, received by the car antenna, identified by the electronic controller ECU, and then executed by the system's actuator to perform the locking and unlocking actions. The system mainly consists of a transmitter and a receiver.

How to Use the Battery Correctly?

The correct usage methods of the battery: 1. Regularly clean the dust and dirt on the surface of the battery; 2. Do not use the starter continuously, each starting time should not exceed 5 seconds. If it fails to start at the first attempt, pause for more than 15 seconds before the second attempt. If it fails to start after three consecutive attempts, identify the cause and fix the issue before starting the engine again; 3. When installing or moving the battery, handle it gently and avoid knocking or dragging it on the ground. The battery should be securely fixed in the vehicle to prevent vibration and displacement during driving; 4. When using the battery in winter, pay special attention to keeping it fully charged to prevent the electrolyte from freezing due to reduced relative density; 5. For batteries in parked vehicles, perform a supplementary charge every two months.

How to Determine if the Brake Master Cylinder is Faulty?

Methods to determine if the brake master cylinder is faulty: 1. Soft brakes: When pressing the brake pedal, if the braking feels noticeably soft, it may indicate poor piston sealing in the master cylinder; 2. Sudden brake failure: This suggests severe oil leakage in either the master cylinder or the wheel cylinders, requiring immediate repair; 3. Brake pulling: If the vehicle pulls to one side and steering becomes difficult to control, it may be due to piston expansion in the master cylinder, necessitating prompt repair; 4. Brake pedal not returning or slow to return: Check for damage to components in the master cylinder or wheel cylinders. The brake master cylinder is a critical component of the vehicle's braking system. If any issues with the braking system are noticed during daily driving, it is advisable to visit a corresponding 4S shop or auto repair shop for inspection and repair.
