How does the car move?

1, one. Transmission system: The power emitted by the car engine is transmitted to the driving wheels by the transmission system. The transmission system has functions such as deceleration, variable speed, reversing, interrupting power, inter-wheel differential and inter-axle differential. It works with the engine to ensure the normal operation of the car under various working conditions, and has good dynamics and economy.

2. Powered by the engine, the transmission speed change and the main deceleration are transmitted to the wheels through the semi-axle. Hope to adopt.

3. Sit in the car, light the car, and step on the accelerator to set off. This is what a rare thing we usually do. However, I'm afraid many people don't know much about the process of car engines from static start to operation.

4. Continue to turn the key to oN (If the key can't be turned, it is likely that the steering wheel is locked. Just turn the steering wheel gently and squee it), and then stop waiting for 6-10 seconds to let the oil pump relay absorb. Start the engine, and then observe whether the indicator light of the instrument is normal.

5. The power of the car is transmitted to the main reducer and differential through the transmission of the engine, and then to the drive wheel through the semi-axle. Give the car a forward thrust through the friction between the driving wheel and the ground. The car started to move. The purpose of the teaching can be to understand the basic working principle of cars.

How to start the right way to start the car

Start smoothly and have the correct posture. When starting normally, it is required to be stable, safe and fuel-efficient. At the same time, you should have a correct driving posture, look far and near, always look at the road and traffic conditions ahead, and do not look down at the parts. When starting, try to avoid forward rush, shaking, shutdown, intermittent arching and other phenomena. Only a smooth start can save fuel.

Adjust the seat after getting on the car. If our legs can't be flexed and stretched freely, it will be very tiring to control the throttle and clutch for a long time.

The starting method of the car is to step on the foot brake and pull the gear to N gear; turn the key, turn half a turn, and start the engine; wait for the engine to turn for about 1 minute, listen to the sound of the engine turning and turn less, step on the foot brake, pull the gear to D gear, release the handbrake; master the steering wheel, slowly release the foot brake, and the car will start automatically. .

After the self-test is completed, turn on the power and start. Step on the brake and hang the D gear. Release the handbrake.

How does the car move?

Engine burningThe expansion of the material combustion gas pushes the piston to make the wheel rotate. Because the wheel has a backward (basically backward) force on the ground, the friction force between the ground and the car is generated, and the car also moves.

The original car was a rack car. Its power depends on manpower, and the rack car is still in use. Later, carriages and donkey carts appeared, and their power was horses and donkeys. In modern times, cars appeared, and their power was diesel and gasoline.

The clutch is located in the flywheel shell between the engine and the gearbox. The clutch assembly is fixed on the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox.

First, start the vehicle switch, and then rely on the battery to supply the power, and let the starter drive the engine crankshaft and piston to start the engine.The kinetic energy generated by the motive is transmitted to the drive wheel through the clutch fitting and the gearbox at the transmission ratio of the corresponding gear. The drive wheel begins to rotate, and the vehicle begins to move or backward. The car began to move.

How to start the car

1. Ignition switch The ignition switch is the last step to start the car. When operating, the ignition switch should be turned to the "start" position. Because the position of the ignition switch is generally high, you should pay attention to Exactly, otherwise an accident may happen.

2. Manual transmission car: Before getting on the car, you need to check the surrounding environment to ensure safety. After getting on the car, put the gear in neutral gear and step on the brake and clutch at the same time. Then turn the key to on gear and wait for the engine self-inspection to start the car.After waiting for 30 seconds, check the dashboard for any faults. If there is no abnormality, you can leave.

3. How to start the car is as follows: 1. Automatic gearshift car: The automatic gearshift car needs to look around the vehicle, open the door after confirming the safety, confirm that the gear is in front of the parking gear, step on the brake, and then press the button to start the button. The car will idle for about 30 seconds, check whether the indicator light on the dashboard is abnormal, check whether it is in D gear, and prepare to drive.

4. Before starting the car, hang the idle gear and shake it left and right to make sure it is in the idle position. The specific method is shown in the figure below. When starting, step on the clutch with your left foot and step on the foot brake with your right foot. Turn the ignition switch to the right with your right hand. After the circuit is turned on, the light on the dashboard will turn on.

5. The correct order to start the car: turn the key to the connection position.Step on the foot brake and pull the gear from P gear to N gear. Release the foot brake, turn the ignition key to the ignition gear, and start the engine. Step on the foot brake, release the handbrake, and pull the gear from N to D.

6. Steps to start the car correctly: 1. After getting on the car, adjust the seat to suit you, and then fasten the seat belt. Start the car, then step on the clutch with your left foot and hang the first gear. Turn on the left turn signal and signal with the horn.
