What is the function of the transmission? What is the function of a transmission?

1.Change the transmission ratio to meet the needs of traction under different driving conditions, so that the engine can work under favorable working conditions as much as possible to meet the possible driving speed requirements. Change the magnitude of the car's driving speed and the magnitude of the torque on the car's driving wheels over a wide range.

Due to the different driving conditions of the car, the speed of the car is required.

2.Realize reversing driving, which is used to meet the needs of backward driving of automobiles. To realize the reverse driving of the car, the engine crankshaft can generally only turn in one direction, and the car sometimes needs to be able to drive backwards, therefore, the reverse gear set in the gearbox is often used to realize the reverse driving of the car.

3.Interrupt power transmission to the drive wheels when the engine is starting, idling, changing gears, or when the car needs to be stopped for power take-off.

4.Achieve neutral, when the clutch is engaged, the transmission can not output power. For example, the driver can be guaranteed to release the clutch pedal to leave the driver's seat when the engine does not turn off.

The function of the transmission is to change the speed and torque, and it allows the vehicle to reverse and idle the park.

What is the function of a car transmission?

1. Change the transmission ratio: One of the functions of the transmission is to change the transmission ratio, so as to change the driving speed of the car and the torque on the driving wheels of the car, so that the engine works in the most favorable situation.

2. Realize reversing driving: The second role of the transmission is to realize reversing driving.

3. Interrupt power transmission and realize neutral gear: The third function of the transmission is to interrupt power transmission and realize neutral gear.

It's good to make the speed fast or slow.

The main functions of the transmission are:

1. Change the transmission ratio to meet the needs of traction under different driving conditions, so that the engine can work as much as possible under favorable conditions to meet the driving speed requirements.

2. Realize reversing driving, which is used to meet the backward driving of the car.

3. Interrupt the power transmission, interrupt the power transmission to the drive wheels when the engine starts, idles the operation, changes gears or needs to stop.

4. Realize neutral, when the clutch is engaged, the gearbox stops outputting power.

Extended information: simple transmission has the advantages of high efficiency, simple structure and convenient use, but the number of gears is small, and the range of change is small (traction, speed range is small), and it is only suitable for some lathes with few gears. If the range of i is increased, the size of the transmission is increased, the shaft span is increased, and in order to increase the number of gears without making the shaft span too large, a constitutive transmission can be used.

The so-called component transmission is usually composed of two simple transmissions, of which the more gears are called the main transmission, and the less is called the auxiliary transmission.

1. Change the transmission ratio to meet the needs of traction under different driving conditions;

2. Realize reversing driving, which is used to meet the needs of reversing driving;

3. Interrupt power transmission;

4. Achieve neutral gear. Transmission, also known as gearbox, is a mechanism used to change the speed and torque from the engine, and can fix or shift to change the transmission ratio of the output shaft and the input shaft.

Transmissions are divided into:

1. Step-by-step transmission: gear transmission is adopted, with several fixed-value transmission ratios;

2. Continuously variable transmission: the transmission system of any transmission ratio in the transmission range can be continuously obtained.

The transmission is a mechanism used to change the speed and torque from the engine, which can change the output shaft and input shaft transmission ratio in fixed or divided gears, also known as the gearbox. The transmission is composed of two parts: the transmission mechanism and the transmission control mechanism, which is an important spare part of the whole vehicle.

Gearbox, also known as transmission, is an auto part used to change the speed and torque from the engine, and can fix or bind to change the transmission ratio of the output shaft and the input shaft.

The automobile transmission is a set of transmission devices, which functions as follows: 1. Coordinate the speed of the engine and the actual driving speed of the wheels; 2. Give full play to the best performance of the engine. Transmissions can create different gear ratios between the engine and the wheels while the car is in motion.

Variable speed and torque change, reverse driving, interrupt power transmission.

The function of the transmission and the precautions for operation can realize multiple transmission ratios to expand the range of torque and speed of the car to adapt to different driving conditions.

The functions of the gearbox are: 1. Change the transmission ratio and expand the range of torque and speed of the driving wheel. 2. Under the condition that the direction of rotation of the engine remains unchanged, the car can drive backwards.

3. Use neutral gear to interrupt power transmission, so that the engine can start and change gears, and facilitate the transmission to shift gears or carry out power output. 4. The transmission is composed of a transmission mechanism and a control mechanism, and a power take-off can also be installed when necessary.

Automobile gearbox: divided into manual and automatic two, manual gearbox is mainly composed of gears and shafts, through different gear combinations to produce variable speed and torque; The automatic transmission AT is composed of a hydraulic torque converter, planetary gears and a hydraulic control system, which achieves variable torque through hydraulic transmission and gear combination.

Manual transmission, also known as manual transmission, is to change the gear meshing position in the transmission by hand, change the transmission ratio, so as to achieve the purpose of shifting. When the clutch is pressed, the gear lever can be activated. If the driver is skilled, a car with a manual transmission can accelerate and overtake faster than an automatic transmission, and it is also fuel-efficient.

AMT gearbox is a kind of manual gearbox, its advantage is fuel saving, cheap, the disadvantage is that there are few application models, and the technology is not mature enough. If the "manual automatic" is to make the ordinary automatic transmission have the feeling of manual transmission, then the AMT transmission is just the opposite, it is based on the manual gearbox, by changing the shift control part, in the overall structure of the same under the condition of the installation of automatic control system to achieve the automation of gear shifting, just like a robot for you to complete the operation of the clutch and the two actions of gear selection.

An automatic transmission uses a planetary gear mechanism to shift gears automatically depending on the degree of accelerator pedal and vehicle speed changes. The driver only needs to control the speed of the vehicle by manipulating the accelerator pedal.

1) Change the transmission ratio, expand the range of torque and speed of the driving wheel, so as to adapt to the often changing driving conditions, and at the same time make the engine work under the most favorable working conditions.

2) Under the condition that the direction of rotation of the engine remains unchanged, the car can be reversed.

3) Use neutral gear to interrupt power transmission so that the engine can start, idle, and facilitate the transmission to shift gears or carry out power output.

1. Coordinate the speed of the Muchan engine and the actual driving speed of the family's durable wheels; 2. Give full play to the best performance of the engine. The transmission can produce different gear ratios between the engine and the wheels while the car is moving.

1. Change the transmission ratio.

Expand the range of torque and speed of the drive wheel to adapt to the often changing driving conditions, and at the same time make the engine work under favorable conditions (higher power and lower fuel consumption).

2. Under the condition that the direction of rotation of the engine remains unchanged, the sleepy car can drive backwards.

3. Use neutral gear to interrupt power transmission, so that the engine can start and idle, and facilitate the transmission to shift gears or carry out power output.

The functions of the transmission are: 1. Change the transmission ratio: expand the range of torque and speed of the drive wheel to adapt to the frequently changing driving conditions, such as starting, accelerating, uphill, etc., so that the engine can work under favorable working conditions.

2. Under the premise that the rotation direction of the engine remains unchanged, the car can drive backwards. 3. Use neutral gear to interrupt power transmission so that the engine can start, idle, and facilitate the transmission shift or power output.

The function of the transmission: 1. Change the transmission ratio. 2. Interrupt the power transmission and realize neutralization. 3. Realize reversing driving.

A transmission is a set of transmission devices used to coordinate the rotational speed of the engine with the actual driving speed of the wheels, and is used to give full play to the best performance of the engine.

Change the gear ratio: Change the gear ratio, thereby changing the speed of the car and the magnitude of the torque on the car's drive wheels, so that the engine works in the most favorable situation. When the car is driving, due to the different surrounding environment, its engine needs to work in different states to meet the needs of the environment.

Interrupt power transmission and neutralize: When the clutch is engaged, the transmission does not output power, and when the clutch is not engaged, but placed in neutral, the transmission can also do not output power. This function of the transmission allows the driver to leave the driver's seat even when the car is not turned off.

The transmission is also required to interrupt power transmission when the engine is started, the car is shifting gears, or when it needs to be stopped.

Realize reversing driving: In real life, it is often necessary to make the car drive backwards, but the crankshaft of the engine can only turn in one direction, because there is a reverse gear set in the transmission, so we can make the car drive backwards.

Interested friends can learn about this problem, and we hope it will be helpful to you. The function of the transmission is to change the speed and torque, and it can enable the vehicle to achieve the function of reversing and idling. The gearbox is an important part of the car, just as important as the engine.

Including manual transmission and automatic transmission, automatic transmission includes AT transmission, DCT transmission, CVT transmission and AMT transmission. Specifically: Gearbox:

This gearbox is the earliest automatic transmission, and the structure is no different from the manual transmission, except that a set of control mechanisms is added on the basis of the manual transmission, which can shift gears and control the clutch. Gearbox: This kind of gearbox, also known as torque converter gearbox, is currently the most mature and widely used gearbox.

The AT gearbox shifts smoothly and durably. Gearbox: This kind of gearbox is also called dual-clutch gearbox, which is the most popular gearbox nowadays.

The structure of the dual-clutch gearbox is very different from that of the manual transmission, except that it has two sets of clutches that control odd and even gears. The dual-clutch gearbox has high transmission efficiency and fast gear shifting. Gearbox:

This type of gearbox is also called continuously variable gearbox. The CVT gearbox is lightweight and small in size. Cars equipped with a CVT gearbox are generally more fuel-efficient.
