are different: automatic transmission does not need the driver to manually shift gears, and the vehicle will automatically select the appropriate gear according to the speed of driving and traffic conditions. Manual transmission is a transmission device used to change the speed and torque transmitted by the engine to the drive wheel.
Transmission principle Manual transmission is mainly composed of gears and shafts, which generate variable speed and torque through different gear combinations; while automatic transmission AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, which achieves variable speed and torque through hydraulic transmission and gear combination.
The working principle of automobile automatic transmission is to use the planetary gear mechanism to change speed. The power of the engine is transmitted through the gearbox, and the gearbox is also a key indicator to measure fuel consumption.Generally speaking, the fuel consumption of automatic transmission is more than 10% higher than that of manual transmission. Whether it is a manual or an automatic transmission, the more gears, the more fuel-efficient it will be.
Therefore, the biggest difference between manual transmission and automatic transmission is the difference in comfort. One requires manual selection, and the comfort of one more operation steps will be relatively poor. The other is automatic gear shift, which frees the hands of car owners and makes driving easy and comfortable.
Automatic does not require the use of clutch pedals. Its clutch has the function of automatic clutch, so there are only accelerator pedals and brake pedals, but no clutch pedals. The gear is only the starting gear and the driving gear.
The difference between automatic gear and manual gear is that automatic gear is transmitted by hydraulic oil, while manual gear is transmitted by mechanical gears. Because the automatic gear relies on the size of the trottle to control the speed, the fuel consumption is relatively high!It is not conducive to environmental protection. The so-called automatic gear is a car that the driver can drive away without a clutch.
Clutch, as the name implies It is the combination or separation of the power that controls the engine and the transmission system that drives the wheels.It is not combined like a gear, but a disc-shaped wear-resistant plate is combined by friction. Step on the clutch pedal, slowly release the pedal, and gradually combine by friction.

Generally speaking, the fuel consumption of automatic transmission is more than 10% higher than that of manual transmission. Whether it is a manual or an automatic transmission, the more gears, the more fuel-efficient it will be.
In the process of driving, the car will use different gears, and the gear shift is generally a gear shift or other gear mechanism, so that one gear vice of the original gear can be pushed out for transmission, and then the gear vice of the other gear can work.
Change the transmission ratio (tooth ratio) of the meshing gear by tuning the fork, and then change the driving torque to adapt to different working conditions. Move the sliding gear in the gearbox below to slide it to the corresponding gear, so that the main gear and the gear mesh to output power to drive the car.
The speed reduction principle of gear transmission is mainly applied in automobile gears. Simply put, there are multiple groups of gear vices with different transmission ratios in the gearbox, and the gear shifting behavior when the car is driving, that is, the different gear vices in the gearbox work through the control mechanism.
Clutch, the parts used to connect the engine and the gearbox. After the clutch is connected, the engine and the gearbox "bite", and the engine runs with the gearbox. After the clutch is separated, the connection between the engine and the gearbox is disconnected. At this time, it is stepping on the accelerator, and the engine is just idling.
Motorcycles are actually the same as cars. In low gears, the speed is slow, but the torque is large. In high gears, the speed is fast, but the torque is small. This is like a reducer with a clutch, because the engine will rotate all the time as long as there is a little fire, and the rotation speed is also Not low.
Now the motorcycle engine has a lot of horsepower, and the fifth gear is to speed up and save fuel. If the 70 motorcycle has five gears and runs less than 100 miles, the engine can't keep up. The wind and resistance are too great. Generally, motorcycles are in cyclical gear, and each one is one hook two.
Fourth and fifth gears should be used, and sometimes third gears can be used if the speed is too slow.Even if the speed is the same, there may be differences in different gears at different moments, and the power situation of different models of motorcycles is not the same in each gear. In short, if you feel that there is plenty of power, you can increase the gear, and on the contrary, if you feel that there is insufficient power, you should reduce the gear.
There are five gears for motorcycles, and the usage method is as follows: one gear, starting gear, and the gear for starting the car. Compared with the reverse gear, the performance is basically the same, so it is not suitable for continuous high-speed operation. Generally, the car can be changed to the second gear after inertia.
The emergence of high-speed and low-speed gears can better meet the requirements of vehicle speed and power under different road conditions, so each gear has its own potential role.
The principle of car gear shift is to achieve gear shift by changing the transmission gear.There are gears in different gears on the wheel hinge. When gears of different sizes are combined with engines, due to different sizes, the circumferential speed of the large gear is less than that of the small gear, so as to achieve the change of speed.
Car gear principle: When the gear is joined, the input shaft changes, transmitted by the intermediate shaft, and finally output to the differential in the output shaft. When the differential moves, the tires also move.
The principle of automobile gear forward gear D gear is the forward gear. Its principle is to meggge all the energy through the transmission to produce the transmission ratio of forward movement. This transmission ratio is generally between 3-9.
Car gear principle: gear shift, input shaft change, output shaft output to differential, differential movement, tire movement. Active gear (connected to the engine through the clutch) connectionReceive the power of the engine and drive the driven gear (connected to the wheel through the main reducer and the drive shaft), thus driving the rotation of the wheel.
The speed reduction principle of gear transmission is mainly applied in automobile gears. Simply put, there are multiple groups of gear vices with different transmission ratios in the gearbox, and the gear shifting behavior when the car is driving, that is, the different gear vices in the gearbox work through the control mechanism.

1. In the first case, the heating resistance and insulation resistance are connected in series. When the insulation resistor is short-circuited, only the heating resistor is working. At this time, it is a high-temperature gear, and the heating power is P=U2/R plus. When two resistors are connected in seriesAt the same time, it is a high-temperature gear, and the insulation power P=U2/(R plus + R protection) is the second case, and the two resistors are connected in parallel.
2. Different gears have different resistance sizes. Electric heating appliances are usually designed with "high-temperature gear" and "low-temperature gear". According to the electric power formula P=U2/R, it can be seen that when U is constant, the greater the resistance, the smaller the electric power; the smaller the resistance, the greater the electric power, so the total resistance of the high-temperature gear is the smallest, and the low temperature The total resistance of the gear is the largest.
3. The automatic transmission adds the electronic valve control principle. The car shift diagram has the following two parts: nut tightening indication: the distance from the center of the nut to the end of the wrench is 0.1 meters, and the force required to turn the wrench is 2 Newtons. According to the formula M=F*L, the torque of screwing this screw is 0.2N/m.
4. When gearing, the blue small gear is connected to the green large gear.The following figure is a cross-sectional view. It can be seen that the blue gear rotates once, and the green gear only rotates half a lap. The wheels it drives roll quite slowly, and the speed is relatively slow. At this time, the force point is at the left arrow, and the red double arrow line is the length of the force arm.

When gears of different sizes are combined with engines, due to different sizes, the circumferential speed of the large gear is less than that of the small gear, so as to achieve the change of speed.
The principle of automobile gear: hang the gear, the input shaft is changed, and through the transmission of the intermediate shaft, the output shaft is finally output to the differential. When the differential moves, the tire also moves.

Whether it is a manual or an automatic transmission, the more gears, the more fuel-efficient it will be.
The principle of overspeed OD is to allow the automatic transmission to overload. If the automatic gear is turned off, its gear will automatically drop under hard acceleration. As long as not all upward gearing OD gears are disabled, its available gears are constantly increasing their power.
