Transmission on Car Meaning
Definition
The transmission is a part of the car’s drivetrain that transfers power from the engine to the wheels. It allows the car to move forward and backward, and to change speeds.
Types of Transmissions
There are two main types of transmissions: manual and automatic.
- Manual transmissions require the driver to shift gears manually. This type of transmission is typically found in sports cars and performance vehicles.
- Automatic transmissions shift gears automatically, making them easier to drive. This type of transmission is typically found in passenger cars and SUVs.
Parts of a Transmission
A transmission consists of a number of different parts, including:
- Gears: The gears are the part of the transmission that actually transfer power from the engine to the wheels. They are made of metal and have different sizes and shapes.
- Shafts: The shafts are the part of the transmission that connect the gears to each other. They are made of metal and are typically hollow.
- Bearings: The bearings are the part of the transmission that allow the gears and shafts to rotate smoothly. They are made of metal and are typically lubricated.
- Synchronizers: The synchronizers are the part of the transmission that prevents the gears from grinding when they are shifted. They are made of metal and are typically coated with a friction material.
How a Transmission Works
When the driver shifts gears, the transmission uses the gears, shafts, bearings, and synchronizers to transfer power from the engine to the wheels. The gears are arranged in a specific order, and the driver selects the appropriate gear for the desired speed and driving conditions.
The shafts rotate the gears, and the bearings allow the gears to rotate smoothly. The synchronizers prevent the gears from grinding when they are shifted.
Transmission Problems
A number of different problems can occur with a transmission, including:
- Slipping gears: This occurs when the transmission does not properly transfer power from the engine to the wheels. It can be caused by a number of factors, including worn gears, damaged shafts, or low fluid levels.
- Grinding gears: This occurs when the gears are not properly synchronized and grind against each other when they are shifted. It can be caused by a number of factors, including worn synchronizers, damaged gears, or low fluid levels.
- Noisy transmission: This occurs when the transmission makes excessive noise, such as whining, grinding, or rattling. It can be caused by a number of factors, including worn gears, damaged shafts, or low fluid levels.
Transmission Maintenance
Regular transmission maintenance is important to keep it running properly and to prevent problems. Some of the most important maintenance tasks include:
- Changing the transmission fluid: The transmission fluid lubricates the gears, shafts, and bearings, and it helps to prevent wear and tear. It should be changed according to the manufacturer’s recommended schedule.
- Inspecting the transmission: The transmission should be inspected regularly for leaks, damage, or other problems. Any problems should be repaired as soon as possible.
Conclusion
The transmission is an important part of the car’s drivetrain. It allows the car to move forward and backward, and to change speeds. Regular transmission maintenance is important to keep it running properly and to prevent problems.
