What are the main components of the actuator? What role does it play?

The power transmission device between the engine and the driving wheels of an automobile is called the driveline of the automobile.

It should ensure that the car has in a variety of driving conditions necessary traction , speed, as well as to ensure that the traction and speed of the coordinated changes between the function, so that the car has good power and fuel economy; should also ensure that the car can be reversed, as well as the left and right drive wheels to adapt to differential speeds. Requirements, and so that the power transmission can be based on the need to combine smoothly or thoroughly and quickly separated

Transmission system includes clutch , transmission, drive shafts, the main reducer, differential and half-axle and other parts. The power transmission device between the automobile engine and the drive wheels is called the automobile's driveline.

Composition of the driveline

Mechanical driveline generally consists of clutch, transmission, universal drive (universal joints and drive shafts), drive axle (main reducer, differential, and half-shafts) and so on.

What are the components of an automotive drivetrain?

Transmission

Functions: ① realize the variable speed torque. ② realize the car reverse. ③Interrupt power transmission when necessary. ④To realize power output.

As the transmission is divided into MT, AT, AMT, DCT, CVT and other forms, in accordance with the manual and automatic classification of the two cases, the manual transmission is the most common, the automatic transmission has been more common and has a tendency to replace the manual transmission. Although the types are different, the components are different. But the function is almost the same. Obviously, the automatic transmission structure is more complex, higher technical content, easier to operate, more expensive, more inconvenient maintenance.

Differential

The role of the differential is to change the turning radius of the car, so that the speed of the left and right sides of the driving wheel is not the same, to ensure smooth turning. For rear-drive vehicles, the differential is prone to rattling.

Universal transmission device

Function: in the automobile any pair of inter-axle angle and relative position often change between the rotary axis transmission power.

Drive Axle

The drive axle distributes the power from the universal drive (or transmission) to the left and right drive wheels after reducing speed and increasing torque and changing the direction of power transmission (when the engine is longitudinally mounted) to drive the automobile and allow the left and right drive wheels to rotate at different speeds. The drive axle is the last assembly of the driveline, which consists of the main reducer, differential, half-shaft and axle housing.
