What is the basic principle of car driving?

The basic principle of car driving is that the torque of the engine applies driving torque to the driving wheel through the transmission system, trying to make the driving wheel rotate.The principle of car driving is as follows: Resistance: If a car wants to move, it must overcome the total resistance. When the resistance increases, the driving force of the car must also increase to reach a certain balance range with the resistance.

The basic principle of automobile driving is as follows: Chassis: The function of the chassis is to support the body to receive the power generated by the engine and ensure that the car can run normally. The chassis itself can be divided into four parts: transmission system, driving system, steering system and braking system.

Gasoline engines convert the energy of gasoline into kinetic energy to drive the car. The easiest way is to obtain kinetic energy by burning gasoline inside the car engine. Therefore, the car engine is an internal combustion engine - combustion occurs inside the engine.

The simple understanding of the principle of the car is that the engine forces the four wheels through the transmission system, and then the whole car moves.At present, there are two mainstream engines: turbocharged engine and naturally aspirated engine. The body structure of a car is divided into two types: load-bearing body and non-load-bearing body.

Chassis: The function of the chassis is to support the car body, accept the power generated by the engine, and ensure that the car can run normally. The chassis itself can be divided into four parts: transmission system, driving system, steering system and braking system.

According to the principle of force and reaction force, the ground will also apply a reaction force Ft equal to the size of F0 and opposite direction to the driving wheel. Ft is the driving force that makes the car run, or traction. The driving force acts on the driving wheel, and then it is transmitted to the body through the axle, suspension, frame and other driving systems to make the car run.

Car driving movement law

When the car is driving, the movement of the wheels and body is as follows: When the car is driving, the wheels rotate with the wheel axle as the center, which is a rotating movement. ; The body moves from back to front on the ground, which is a translation movement.

Front and rear bounce movement: When the car passes through an uneven road surface or carries heavy objects, the wheels will constantly bounce back and forth, which also affects the driving condition and riding feeling.

When turning the steering disc, it can drive the pinion gear to rotate. This pinion gear coincides with a rack, driving the left and right linear movement of the rack, and pushing the steering wheel to swing left and right, so as to realize the steering function. The gear is not a simple flat gear, but a special spiral shape, which can improve the suppleness when steering.

The driving speed of the car

1. The maximum speed of small passenger vehicles on the highway shall not exceed 120 kilometers per hour, other motor vehicles shall not exceed 100 kilometers per hour, and motorcycles shall not exceed 80 kilometers per hour. Kilometer.

2. Driving speed. The maximum speed of ordinary small cars is less than 180 yards, high-end imported cars can run at a speed of 250 yards, and high-end imported sports cars can race with high-speed rail up to 350 yards.In China, due to the highway - the speed limit is less than 120 yards, it is of little practical significance for the car to run fast.

3. On the highway, it is generally 80-120 kilometers per hour. When the speed of the car is driving in the urban area, because there are more cars and more people, the speed should not be too fast. When the car is driving on the highway, because the road surface is relatively smooth and the highway is a fast lane, the driving speed should not be too slow.

4. Article 78 Expressways shall indicate the driving speed of the lane. The maximum speed shall not exceed 120 kilometers per hour, and the minimum speed shall not be less than 60 kilometers per hour.

5. The speed of the car should be driven according to the speed under the road speed limit standard. Most of the high-speed speed limits in China are 120 km/h.The speed limit of the national highway is generally 80-60 km/h. Streets are generally 40-30 km/h.

6. The speed of the car should be 30-60 kilometers per hour when driving in urban areas, 80-120 kilometers per hour on highways, and about 60-80 kilometers per hour in ordinary urban areas. When cars are driving in urban areas, it is generally maintained at 4 due to the large number of cars. Just drive at a constant speed of 0km.

What is the reason why the car shakes while driving

1. There are many reasons for the body shaking when the vehicle is driving. These include tire dynamic balance, hub balance block shedding, hub mud on the hub, aging of chassis rubber parts, and large differences in front bundle and inclination data, loose chassis suspension, road feedback, etc.

2. (2) Tire imbalance: Some car owners unbalance the tire movement after removing the tire, which will cause high-speed steering wheel to shake. Generally, go to the tire store to balance the tire movement can solve the problem; (3) Tire deformation: carefully touch the four tire treads of the car with their hands.

3. The main reason for idling jitter: serious engine carbonization: cars always have the problem of carbon accumulation, including cylinder carbonization, throttle valve carbonization, spark plug carbonization, intake carbonization, etc.
