Latest update date: February 24, 09

Drive system includes main components such as transmission, driveshaft, differential, and other components such as coupling, direction changer, and transmission mechanism. Each component plays an important role in ensuring the efficient transmission of power from the engine to the wheels, helping the vehicle move smoothly and safely.

In addition, advanced technologies such as four-wheel drive system (4WD/AWD), clutch torque control system (torque vectoring), and electric drivetrain system have been integrated. into the drive system of many modern car models. These technologies contribute to improving the vehicle's road holding ability, ability to operate on many different terrains, and fuel efficiency.

Understanding drivetrain systems is not only important for engineers and automakers, but also helps consumers better understand how their vehicles work, so they can make informed choices. Choose and use vehicles more effectively and safely.

In this article, Thanh Phong Auto will provide important information about the car's steering system.

What is Automotive Shaft?

1. Concepts

The automobile crankshaft has a cylindrical shape, belonging to the automobile transmission system with the task of driving from the car gearbox or differential to the wheel axles for the car to move.

2. Classification

Automotive drive shafts are divided into two main types:

  • Single shaft: usually made of aluminum or steel with high strength, light weight; used on 4-wheel vehicles with a small distance between the engine and the axle.
  • Two-three-piece crankshaft: used for 4-wheel vehicles with a large distance between the shaft and the engine.

3. Structure

The driveshaft of a car is composed of 9 main parts:

  1. Center shaft: the main part of the moving shaft and the articulating shaft linked to the housing on the center bearings.
  2. Tubular shaft: the part that helps to correct the gear ratio and the rear axle.
  3. Tube: maintains the rear position of the vehicle when accelerating or braking.
  4. Center bearing – middle bearing: links the 2 parts of the crankshaft, maintaining the position of the transmission.
  5. Flange: connect the shaft to the transmission, gearbox, differential...
  6. Coupling (U-joint): connects the rotating axles of the vehicle, drives the wheels to move the vehicle.
  7. Stopper: reduce vibration and noise when the vehicle accelerates.
  8. Slide pin: connect with drive shaft, move outside the transfer box to supply power.
  9. Pipe pin: rotates around the coupling and drive shaft.

In addition, the car drive system has a number of other components such as anti-lock braking system, torsion damper, etc.

Common Problems With Steering Wheels In Cars

1. Rusted shaft gears

Signs: the car starts up with a loud, jerky and sluggish sound than usual.

Cause: the car moves in the rain, in a flooded area or improperly cleaning the car causes water to overflow and collect in the compartment - not dried in time, so the gears are oxidized.

2. Worn transmission gears and speed joints

Worn gears and synchronous joints will reduce transmission power, if prolonged, it can break, chipped gears, making cars unable to move.

Signs: appear "pop" sound when hugging a crab.

Cause: gears, synchronous joints are affected by friction, so it is difficult to avoid wear and damage after a long time of operation; especially when it is not lubricated or the lubricant is contaminated with dirt.

3. The stick is broken

Appears croaking and louder when running straight.

4. Lubrication of the axle shaft

Grease in the crankshaft must be of a special type used for the crankshaft, if used incorrectly, it will flow out through the rubber door slot.

5. The shaft cover is torn

Because it is made of rubber, the shaft cover can be torn by rubbing during vehicle operation. It is necessary to replace this part as soon as there are signs of tearing to avoid sand and dirt getting in and abrading the parts inside the bearing.

As an important part in the operation of a car, the power steering system needs to be checked and maintained periodically to promptly detect and fix problems - to avoid affecting vehicle quality and safety. safety of occupants and costly repair costs.

Frequently Asked Questions (FAQ)

1. What is the average lifespan of a car steering system?

The lifespan of the drive system depends on many factors such as component quality, operating conditions, and maintenance regime. In general, under normal use conditions, the tire system can operate well for about 150.000 - 300.000 km.

2. How often is the recommended frequency of maintenance of the drive system?

Manufacturers often recommend maintenance of the drive system every 20.000 - 30.000 km or every 12 - 18 months depending on usage conditions. Regular maintenance helps detect damage early and prolong the life of the system.

3. What are the signs that the drive system is having problems?

Some common signs include:

  • Strange noises and unusual vibrations appear when the vehicle moves
  • Oil leaks from joints and shafts
  • The car jerks when accelerating or shifting gears. See details in the article: Countless cars jerk while driving – Causes & most effective solutions are updated on the website.
  • The powertrain error light illuminates on the dashboard

4. What is the average cost of repairing and replacing a car's drive system?

The cost of repairing and replacing the roof system ranges from several million to several tens of millions of VND depending on the level of damage and component prices of each vehicle model. For example:

  • Replacing the driveshaft joint: 2-5 million VND
  • Replacing the driveshaft: 5-15 million VND
  • Gearbox replacement: 20-80 million VND

5. What mistakes when using the vehicle can cause the steering system to fail faster?

Mistakes that cause the drive system to fail quickly include:

  • Let the vehicle start and move immediately without warming up the engine
  • Shift gears suddenly, not gently
  • Brake, accelerate quickly
  • Carrying excess load
  • Driver collides with obstacles and potholes on the road

6. Do automatic and manual transmission cars have the same transmission system?

Basically, the tire systems on these two types of vehicles have the same function: transmitting power from the engine to the wheels. However:

  • Manual transmission cars use a mechanical clutch and transmission
  • Automatic transmission vehicles use automatic transmissions and hydraulic torque converters, so the structure and operating principles are somewhat different.

7. How is the drive system technology on electric cars different from traditional cars?

Electric cars use one or more electric motors to directly drive the wheels. This system has a simpler structure, including the following main parts:

  • Electric motor (instead of internal combustion engine)
  • Electronic control unit (ECU)
  • Gearbox (usually only 1 speed)
  • Propeller shaft Compared to the traditional drive system, the system on electric cars is lighter, more efficient, has less wear and tear but is more expensive.
