What is the function of the car s drivetrain

The role of a car's drivetrain is to transmit the power emitted by the engine to the driving wheels on the car.

The automobile transmission system is mainly to transmit the power sent by the engine to the driving wheels on the car, so as to generate driving force, so that the car can drive normally, generally composed of clutch, transmission, universal transmission device and differential, when the driving wheel gets the torque given by the engine, a forward reaction force is generated, so as to form a driving force to drive the car.

Its composition and arrangement are also changed according to the type of engine and the installation position, for the common front-wheel drive model, its drive train is less than other models of the drive shaft, and for the four-wheel drive model to increase the transfer case and other assembly.

Precautions for automotive drivetrains:

1. Ensure the normal driving of the car: as the function of deceleration, speed change, reversing, interruption of power, inter-wheel differential and inter-axle differential of the drive train, it cooperates with the power given by the engine, so as to ensure the normal driving of the car under various working conditions, and also has good power and fuel economy for the car.

2. Interrupt power transmission: For the car, the power of the body should be disconnected when starting, and when changing gears and emergency braking, in order to reduce the impact on the owner, the power must be disconnected, which is actually the role played by the drive train.

The transmission system is generally composed of a clutch, a transmission, a universal transmission, a final reducer, a differential and a half shaft. Its basic function is to transmit the power emitted by the engine to the driving wheels of the car, generating driving force so that the car can drive at a certain speed.

The composition and arrangement of the drive train varies depending on the type of engine, the location of the installation, and the purpose of the car. For example, off-road vehicles mostly use four-wheel drive, so an assembly such as a transfer case is added to its drive train. For front-wheel drive vehicles, there are no transmission shafts and other devices in its drive train.

Functions of the transmission system:

1) deceleration and torque increase, the power output of the engine has the characteristics of high speed, small torque, can not meet the basic needs of the car driving, through the main reducer of the transmission system, can achieve the purpose of deceleration and torque increase, that is, the power transmitted to the driving wheel is lower than the power speed of the engine output, and the torque is large.

2) variable speed and torque change, the optimal working speed range of the engine is very small, but the speed of the car and the resistance that needs to be overcome are changed in a large range, through the transmission of the transmission system, it can meet the needs of the large change in the driving speed of the car and overcome various driving resistance under the condition that the working range of the engine does not change much.

3) To achieve reversing, the engine can not be reversed, but the car in addition to moving forward, but also reverse, in the transmission to set the reverse gear, the car can achieve reversing.

4) Interrupt the power transmission of the transmission system when necessary, start the engine, in the process of shifting gears, stop for a short time during driving (such as waiting for traffic lights), and the car slides at low speed, etc., all need to interrupt the power transmission of the transmission system, and the power transmission can be interrupted by using the neutral gear of the transmission.

5) Differential function, in the case of automobile steering, etc., two drive wheels are required to be able to rotate at different speeds, and the differential function can be realized through the differential in the drive axle.

The role of the car's drivetrain is to generate power, as follows:

1. It is generally composed of clutch, transmission, universal transmission device and differential;

2. The system mainly transmits the power emitted by the engine to the driving wheels on the car, so as to generate driving force and allow the car to drive normally;

3. When the driving wheel gets the torque given by the engine, a forward reaction force is generated, so as to form a driving force to drive the car.

Generally, most automobiles use a mechanical drive train, which consists of a clutch, a transmission, a rotating shaft with a universal joint, and a drive axle with a reducer, a differential, and a half-shaft drive axle. Function: Transmit the power of the engine to the drive wheels. The function of the clutch:

1. Ensure the smooth start of the car, 2. Ensure the smooth change speed, 3. Prevent the transmission mechanism from being overloaded. Functions of the transmission:

1. Adapt to the change of the driving resistance of the car, and change the traction and speed of the car.

2 Without changing the direction of rotation of the engine crankshaft, the car can be reversed.

3. When the clutch is engaged, it can ensure that the engine idles and does not transmit the power of the engine to the driving wheels.

4. If necessary, the power can be transmitted to other institutions through the power take-off. The function of the universal joint: the transmission shaft can smoothly transmit the power of the transmission (or transfer case) to the reducer gear under various different angles, and can avoid the damage of the transmission shaft parts.

The function of the reducer: change the direction of the axis of rotation of power transmission, and at the same time reduce the speed and increase the torque. Functions of the differential:

When the car is driving in a turn or on an uneven road, it can automatically make the speed of the two driving wheels different. Some multi-axle drive cars also have differentials in the transfer case or between the axles of the transfer case to the drive axle, and its function is to produce a difference between the front and rear drive wheels when the car turns or drives on uneven roads. The function of the half shaft:

The torque from the differential is transferred to the wheels, which is used to drive the wheels to rotate and propel the car to drive.

The functions of the automobile drive train are: 1. It ensures that the car has the necessary traction and speed under various driving conditions, and ensures the coordinated change between traction and vehicle speed, so that the car has good power and fuel economy; 2. It also ensures that the car can drive and reverse, and the left and right drive wheels can adapt to the differential demand, and the power transmission can be smoothly combined or completely and quickly separated according to the need. A powertrain system is a device that transmits power between the engine and the wheels of an automobile.

The basic function of the drive train is to receive the power of the engine and transmit it to the drive wheels.

The basic function of the automobile drive train is to transmit the power emitted by the engine to the driving wheels, and the primary task of the automobile drive train is to work with the automobile engine to ensure that the car can drive normally under different use conditions, and has good power and fuel economy. The power emitted by a car's engine is transmitted to the driving wheels by the drive train. The drive train has the functions of deceleration, speed change, reversing, interrupting power, inter-wheel differential and inter-axle differential, etc., and works with the engine to ensure the normal driving of the car under various working conditions, and has good power and economy.

1. It ensures that the car has the necessary traction and speed under various driving conditions, as well as the functions of coordinating changes between traction and vehicle speed, so that the car has good power and fuel economy;

2. It also ensures that the car can drive and reverse, and the left and right drive wheels can adapt to the differential requirements, and the power transmission can be smoothly combined or completely and quickly separated according to the needs.

It is mainly to transmit the power sent by the engine to the driving wheels on the car, so as to generate driving force, so that the car can drive normally, generally composed of clutch, transmission, universal transmission device and differential, when the driving wheel gets the torque given by the engine, it produces a forward reaction force, so as to form a driving force to drive the car.

The function of the drive train of the car is to make the car have a good degree of power and fuel economy.

The transmission system of the car is divided into hydraulic, mechanical, silent night history and electric is the vehicle we buy, especially the fuel of the private car, most of which are front-mounted mechanical drive, and now there are many. New energy vehicles are electric, rear-drive, braking or four-wheel drive.
