How are the six gears of a 6 speed automatic transmission represented? Thank you very much 5

123456 forward gear Specifically, the dashboard has changed from D1 at the beginning to D6 after 80

1. Manual automatic integration is AMT gearbox, which adopts a semi-manual and semi-automatic combination of operation mode, which combines the advantages of automatic transmission and manual transmission respectively, and reduces the damage to the transmission system to a certain extent. It is possible to switch back and forth between automatic and manual transmissions. You can change gears at will, and the driving feeling is relatively smooth.

2. Dual-clutch dual-clutch transmission is referred to as DCT transmission. It is different from other transmissions that are similar to automatic transmissions such as ATs. It is based on a manual transmission (MT) but also an automatic transmission (AT), which has the flexibility of a manual transmission with the comfort of an automatic transmission and provides uninterrupted power delivery.

3. The automatic integration of the fuel consumption hand is a combination of manual and automatic clutch, but it is more inclined to automatic transmission, although the driving is relatively easy, but the loss of fuel is larger. The dual-clutch transmission, on the other hand, is similar to a clutch with two automatic transmissions, and the fuel consumption is not as high as that of a manual transmission.

1.The automatic manual transmission is divided into automatic and manual mode, while the 8-speed automatic manual is the 8-speed transmission of the car, and when the car switches to manual mode, 8th gear is the highest gear.

2.To explain in detail, according to the order of gears from top to bottom, the car of automatic transmission is marked as: P parking gear, R reverse gear, N neutral gear, D forward gear, S acceleration gear, + - is to switch to manual analog plus or minus gear.

The 8th gear reduces engine speed at high speeds, significantly improving comfort while reducing fuel consumption and emissions. Note: The 8-speed gearbox is generally only available on luxury cars.

It's not the same, the 6-speed manual automatic can switch to the manual gear, depending on the driving habits.

The smoother the shift with more gears, the lower the number of revolutions at the same speed, and the more fuel-efficient. The four-speed gearbox is smaller and cheaper, but it should have been eliminated a long time ago, and the ZF has an eight-speed gearbox; The more gears there are, the denser the gears are, and the easier it is to convey the amount of effort required by the engine to the wheels. But the question is 4, 5, 6....

Five gears and six gears.

Reverse gear stage: When the vehicle needs to retreat, the input shaft clutch is disengaged, the reverse sliding gear is meshed with the reverse intermediate gear through the fork, and the reverse intermediate gear is meshed with the input shaft reverse drive gear.

At the same time, the reverse gear variable shaft is linked with the toggle shaft of the locking clutch sleeve, so that the locking clutch sleeve locks the front section of the output shaft and the rear section of the output shaft together through the spline in the locking clutch sleeve in it, and realizes the rotation of the rear section of the output shaft.

The reasons for this are as follows:

1) The clutch is not completely disengaged and cannot completely cut off the power. Specifically, it is manifested in two aspects:

First, due to improper manipulation, the pedal did not step to the end, resulting in incomplete separation and difficulty in gearing. This phenomenon is common in novices, due to unskilledness, often the pedal is not stepped to the end and the gear is in gear, and the gear is not in gear;

the second is the difficulty of hanging gear caused by the poor technical state of the clutch;

2) The tooth ends of individual meshing teeth of the new car are rough, which makes it difficult to hang the gear;

3) The shift fork is loose and bent, the shift fork shaft is bent and corroded, and it is difficult to move, and when the locking screw of the fork shaft fixing the fork is loose, it will also cause difficulty in hanging the gear;

4) The length of the reverse gear lever on the gear lever is not adjusted properly, and when the reverse gear is hung, the rising height of the lock plate is not enough, and it cannot smoothly enter the reverse gear position.

Different models of gearboxes have different gear ratios, and it is impossible to judge by the number of gears alone.

The gear meshing gear of the automatic transmission is similar to that of a manual transmission, and each gear has a corresponding gear ratio, intuitively speaking, the more gears there are, the smoother the gear shift, and the finer the gear corresponding to the vehicle speed, the more economical the fuel consumption; For example, a 4-speed transmission, the engine input and output ratios are: first gear, second gear, third gear, fourth gear, and a 6-speed gear are: first gear, second gear, third gear, fourth gear, fifth gear, six gears, (Generally speaking, the speed ratio is that the engine is input to the transmission rotation, through the transmission gear meshing difference, transmitted to the half-shaft tire for 1 revolution) From the above comparison, it can be seen that when the 4-speed transmission crosses the 1-2-3 gears, the speed ratios are different, so the frustration of shifting gears when starting to speed up is more obvious. In order to ensure the power of the vehicle, the engine must stay in a certain gear for a long time at high speed; The 6-speed transmission, although the difference between the first gear and the second gear is relatively large, but the others are subdivided a lot, the engine speed is slightly higher to match the corresponding gear, the frustration is small and the fuel consumption is economical, especially at high speed The fuel consumption is lower; Like the 8-speed transmission configured in the Q7, you can cruise in 8th gear at speeds above 70 per hour; Of course, the gears of the transmission are not as much as possible, excessive refinement brings about the rise of manufacturing costs, strict processing and assembly and environmental requirements, and the follow-up maintenance costs are expensive, so the ordinary family car generally has a 6-speed transmission is enough; Automatic transmission also has a continuously variable speed, due to the use of hydraulic, electro-hydraulic, mechanical and other ways of propulsion and module control, although there is also a corresponding speed ratio, but under the control of the computer, within a certain speed range, can be continuous, arbitrary speed change, so that the speed is more smooth.

Different models of gearboxes have different gear ratios, and it is impossible to judge by the number of gears alone.

Some large construction vehicles have more than 10 forward gears, and the difference in speed ratio can be imagined.

6-speed manual means that the vehicle's gearbox has 6 forward gears and one reverse gear. We often see in the market that most of them are equipped with manual transmissions.

The vehicles are basically 5 forward gears.

There are very few vehicles equipped with 6 forward gears. The manual gear is also called the MT gear, which is also used to distinguish the automatic gear.

The 6-speed manual transmission system has one more gear than the 5-speed manual transmission, so it will be more fuel-efficient than the 5th gear when running at high speeds. Because the more gears, the smaller the transmission gear inside the gearbox, the gear ratio.

It's big, too. So the advantage in speed is even more obvious.

The more gears there are, the less frustration the gearbox will be when refueling and defueling sharply, so the 6-speed manual transmission still has a lot of advantages over the 5-speed gearbox. Of course, there are advantages and disadvantages, the disadvantage of the 6-speed manual gearbox is that the internal structure of the gearbox is complex, and after the problem, the maintenance cost will be much higher than that of the 5-speed gearbox.

Yes, six forward gears, the transmission ratio is not the same, [the car has a problem, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Car Automatic Transmission Gear Explanation:

1. Generally speaking, the gears of the automatic transmission of automatic transmission vehicles are divided into P, R, N, D, 2 (or S), L (or 1), etc.;

2. P is used for parking, and it is the use of mechanical devices to lock the rotating part of the car, so that the car can not move. As long as the gear lever is in the driving position when the engine is running, the automatic transmission car can easily walk. When parking, the gear selector lever must be pulled into the P position, so that the output shaft is locked by the parking brake device inside the transmission, and the hand brake is tightened to prevent the car from moving.

When the car needs to stay in a fixed position for a long time, or before leaving the vehicle after stopping, the hand brake should be applied and the paddle lever should be pushed into the "P" position. It should be noted that the vehicle must be completely stopped before using the P gear, otherwise the mechanical part of the automatic transmission will be damaged.

When you don't use the park, the gear is here, and the wheels are in a mechanical locking state to prevent slipping. In addition, the neutral shift start switch is installed on the automatic transmission car, so that the car can only start the engine in the "P" or "N" gear, so as to avoid making the car suddenly move forward when starting by mistake in other gears;

3. R is used when reversing. Automatic transmission cars do not use semi-linkage like manual transmission cars, so special attention should be paid to the control of the accelerator pedal when reversing. It is usually necessary to press the safety button on the lever to move the lever to the "R" position.

It should be noted that when the vehicle has not completely stopped, it is absolutely not possible to forcibly turn into "R" gear, otherwise the transmission will be seriously damaged;

4. The n position refers to the neutral gear, which can be used when starting or when the trailer is temporarily stopped (such as a red light); In order to prevent the vehicle from slipping on the slope, be sure to press the brakes when in neutral; With the number of levers buried in the "n" gear, the power between the engine and the transmission has been cut off and separated; If you stay for a short time, you can put the lever in this gear and pull the hand brake lever, and the right foot can be removed from the brake pedal for a short rest; When waiting for a signal or in a traffic jam, the gear selector lever is often kept in the D position, and the brake is pressed at the same time; This is allowed if the time is short, but it is best to switch into the n position and tighten the hand brake if the stop time is long.

The six-speed gearbox and the five-speed gearbox here 6 and 5 do not include reverse gears, that is, there are 6 forward gears and five forward gears respectively, the difference is of course that the former has one more forward gear than the latter.

Whether it's an automatic transmission or a manual transmission, a 7-speed dual-clutch transmission, or a 6-speed automatic manual transmission, or an 8-speed transmission. 9-speed manual, the few speeds here are talking about how many gears there are forward, including the analog gears in the continuously variable gear.

The increase in gears does not mean that the forward speed is increased, but the coordination of the vehicle's speed and the speed of the vehicle is more subdivided, in other words, the vehicle is controlled with a more accurate shift time, so that the vehicle is smoother and more fuel-efficient. To put it simply, if the gears are increased wirelessly, it is called continuously variable gear, and the output curve of the gearbox becomes extremely smooth and without frustration.

Theoretically, the more gears, the more fuel-efficient and smooth.

The difference is that for different number of gears, there are several sets of gear meshing.

Inside the gearbox, several sets of gears mesh with each other, and each set of gears can transfer the kinetic energy of the engine to the tires for propulsion. The number of teeth of each gear is different, and the number of revolutions of each gear is different when it rotates after meshing, so that different speeds and torques can be distinguished.

Different manufacturers have designed different gear sets according to their own engines and vehicle conditions when designing, and if the forward gear is set up with 4 groups, 5 groups, and 6 groups of gears, it will form 4 gears, 5 gears, 6 gears, and 8 gears and 9 gears for high-end cars. The higher the number of gears, the higher the manufacturing precision and complexity.

The more gears, the more active gear shifts, the speed does not need to be a large span and the accelerator does not need to be stepped on a lot, the higher the number of gears, the more fuel-efficient.

The number of gears is divided according to the range of transmission ratios, that is, according to the minimum speed to the maximum speed.

Under a certain range of gear ratios, the more gears, the smaller the interval between the gear ratios, the smaller the impact of shifting, and the most important thing is that there are more gears, large selectivity, and fuel saving. But the more gears there are, the more complex the transmission becomes, and the more expensive it is.

With the development of automatic transmissions in automobiles, there are more and more gears in the forward gears of the gearbox.

The oldest model [1st generation automatic wave] has three gears, and with the continuous maturity of automatic wave technology, the number of gears is increasing. The more forward gears, the better the car's power and economic performance, and the current highest gear has 9 front speeds.

The more gears, the more upscale the handlebars, in general.

With the exception of the continuously variable transmission, the number of gears for both manual and automatic transmissions is limited. At present, we know that the highest in the sedan is 8 gears, that is, 8 forward gears. The lowest on the sedan also has 4 forward gears.

At present, the most common use of 5-speed transmissions, both manual and automatic.

The number of gears has an impact on the power performance, comfort, and fuel consumption of the car. The power output from the engine crankshaft passes through the clutch and is directly fed to the input end of the transmission. At this time, the speed is higher, and the torque is smaller, and the wheel cannot be driven directly, and the wheel must be reduced through a series of rotations, and the torque must be increased at the same time to push the wheel forward.

The function of the transmission is to reduce the high revs of the engine.

In fact, the difference between 4th gear and 6th gear lies in the gear ratio, that is, the speed ratio of input and output.

Introduction: Automatic transmission, as the name suggests, does not need the driver to manually shift gears, the vehicle will automatically choose the appropriate gear according to the speed and traffic conditions. There are six gears on a typical automatic car, from top to bottom:

p、r、n、d、s、l。

Principle: The power of the engine is transmitted through the gearbox to the automatic gearbox, the gearbox is also a key indicator of fuel consumption, generally speaking, the fuel consumption of automatic transmission is more than 10% higher than that of manual transmission. Whether it's a manual or automatic transmission, the more gears you have, the more fuel-efficient.

Point-and-shoot cars: Like point-and-shoot cameras, automatic transmission cars are often thought of as point-and-shoot cars that don't require any driving skills. In fact, if the automatic transmission car is not operated properly, it will also increase the probability of automatic transmission failure, and the correct use of automatic transmission can not only extend the service life of the transmission, but also reduce fuel consumption. There is also automatic driving suitable for women and serious traffic jams in the city, slow acceleration because after all, he is mechanical, although the automatic transmission has S mode when accelerating sharply, but the speed is fixed, generally 3000-4000 conversion gear, the maximum torque of the general naturally aspirated engine must reach 5755-8988 rpm to play the highest torque, and the automatic transmission in order to reduce the roar of the engine and the vibration of the gearbox, take 4000 conversion gear, which makes the acceleration very slow!

However, the automatic transmission of high-end cars is already faster than the manual H gear, for example, the Ferrari California automatic is faster than the manual transmission, and with the advancement of technology such as Tip Tronic, DSG, dual clutch transmission, etc., the automatic transmission has long surpassed the manual H gear).
