Urgent.. Would like to ask about car question 20

After the car engine is started, the power is transmitted through the drive shaft to the gears of the gearbox (there are several sets of gears for several gears), and then to the drive shafts of the wheels through the gears, so that the vehicle can drive. The speed of the vehicle is formed by separating the drive shaft of the machine from the gearbox and closing the gears of different sizes by the clutch.

No, the engine power is transmitted to the gearbox through the clutch, through different gear ratios, it is decided whether the speed increases or decreases, and then it is transmitted to the drive axle, and after the main reduction of the drive axle decelerates and increases torque, it is transmitted to two half shafts, the half shaft is connected to the wheel hub, and the wheel hub is connected to the tire, and finally to the tire... That's how the whole drivetrain is...

In fact, you don't need to understand these relationships to learn to drive, and I still don't understand it, but I can drive it anyway.

The force of the engine is transmitted first to the gearbox and then to the wheels. The function of the clutch is to smoothly combine and disengage the force of the engine and the force of the gearbox.

The engine produces a certain amount of power (related to the number of cylinders and the amount of displacement).

The gearbox is geared of different diameters to turn a certain amount of power into a different rate.

The clutch controls the engagement and disengagement of the gears of the transmission. That is to say, when changing gears, the clutch is detached from the two sets of gears, the gear is jumped to the appropriate position, the clutch is released, the gears are engaged, and the wheels gain forward momentum.

None of them act directly on the wheels. The power of the engine is transmitted to the gearbox, then to the drive axle, which is decelerated and torsioned by the main reduction of the drive axle, and then transmitted to the two half shafts, which are connected to the wheel hub, which is then connected to the tires, and finally transmitted to the wheels.

According to your requirements, the recommended models are arranged in the following order: 1. Chery A3; Ten thousand; 2. Mazda, Jinxiang; 10,000 3, sign 207; Ten thousand; 4, Southeast V3 Ling Yue;; The arrangement of several cars is comprehensively evaluated from several aspects such as body performance, actual use, ride, driving, handling, energy consumption, and cost performance; Each has its own characteristics in this price range, which should be the best; At the same time, these models are relatively generous, especially suitable for family use.

The shape and interior of the car are the opinions of the benevolent and the wise, and you can choose according to your own preferences; However, the technical indicators and overall performance should be comprehensively evaluated and considered as a whole.

The purchase of a car should consider comprehensive factors, the purchase of a car is definitely different from other commodities, in addition to its own products to be good, but also to take into account other factors; In the process of using the vehicle, the purchase cost is only just a quarter of the cost; Most of the expenses are in the later use, repair, and maintenance process.

Therefore, when purchasing a vehicle, in addition to the performance of the car itself, it should also be considered from the following aspects:

1. First of all, look at your own use (don't say it's 'on');Is it used as a means of transportation, or is it used for business?

2. Budget and price; Too high or too low should not be; driving and riding comfort, practicality;

3. The performance of the vehicle; safety, control, energy consumption, maintenance costs, etc.;

4. Manufacturer, this mainly depends on the strength of the manufacturer; Don't be like some domestic companies, do it for n years and disappear, and the unlucky ones are naturally consumers (at present, several cars here have no worries);

5. Daily expenses for repair and maintenance; 3. Filters and common parts and accessories; technical strength and convenience of maintenance;

6. Market share; Some products themselves are good things, but the market share is extremely low, other products are okay, and cars are definitely not good (Poussin and Jetta models are outdated, but they can still sell well, which is an example); Because it is not a three-year-old or two-year-old consumable, and after five years, a car that can't find accessories for personal use, let alone a used car, can't even sell a used car at a high price.
