I'll introduce or transmission which is related to the clutch or the like , which is also the one of the best part of when driving a car or selectively used depending on the situation the power of a motor vehicle in this chapter . Technology of mechanical engineering because it is condensed transmission and I'll be very excited lol
That aside , it can be seen from the transmission , but I will do what exactly ? When I explained that since it may think , transmission is one of the power transmission device , it is a device according to the running state , to change torque optimal manually or automatically , to the rotational speed . The torque that is the ability to rotate in the part which pedaling A good analogy is by bicycle .
It is reason to be just right and is allowed to speed when it is I wanna weakened slightly if , for example, when you go down the hill , and rotation power obtained in the engine . I hope you can grasp the image .
And there can be can be classified into two major , and ( saying Nantes automatic or AT also say well for short) is then automatic transmission (MT for short) manual transmission.
MT(please think of such lever like a UFO catcher in the side of the driver's seat to operate Innovation Get) is a shift lever (it is the pedal that is in the side of the brake pedal.. See below for a description of the terms of clutch) clutch and it is a thing that can select any gear own driver by operating. Should Some people sometimes as an example, I watched the scene Ttoyaru Get the shift lever, such as foreign film.

MT is the very best part of driving a car ! ( ※I've ever driven car because of high school students )
However , the era of the MT are becoming sadly end in Japan now . AT is equipped with passenger car of more than 90% in Japan .
The ride to the MT , it is becoming a trend and not even only those who ride in traffic light and mania and the elderly . AT lists even after , but it is what made me automatically shift change due to the evolution of electronic control . It becomes addicted to one use seems to be addictive to AT Apparently , it can not return to MT anymore! And I have to migrate quickly from the 1990s by people who occurred frequently . It is like a smartphone , you can not return to the other Garake I have switched to once ! Recent description Let me aside , it is whether a mechanism what easily and oh ... It is terrible all the world I think you even climate people Garake is a fool .
Engine→cluch→transmission→wheels
When you press the clutch pedal to the previous driving, it will be in the state of N (Neutral). The N that is the state that cut the power from the engine by cutting off the power from the engine. So it is possible to recombinant gear of the transmission, the transmission torque is not transmitted to the wheels temporarily by doing so.
In response to it and the gear on the engine side , there is a gear on the side to tell the wheels In a nutshell the gear in a transmission . I'd like grabbed the image , but it is expressed in what 's called the degree of the shift that gear ratio . The state of the gear ratio is large is that the rotational speed is reduced torque is increased , the force that is, advance is small. I will be in that rotation that indicates that the number increased torque is reduced if the gear ratio is small in reverse . It is the force that is, advance is large . Gear I'll not go too much But ( torque ) and lighter pedal to one when you I also and are described in that example of the bicycle so often used in the description of these , and do you think of availabling for gear change up to 1-6 ? It is a thing ( rotational speed has decreased ) gear ratio is large this is . I'll go more and more instead of pedal is heavy and to 6 gear as well . That is that the gear ratio is small . At the same the same thing . By the way, I every morning late last moment I'm rowing in a small gear ratio at all times . . . sweat
(This photo which I taken my dad's bike's transmission.)
Gear ratio will come determined by the number of teeth of the gear on the side where the remedy for a gear on the engine side ( gear drive ) .
Transmission ratio can be calculated by the gear to the number of teeth of the gear drive ÷ the receiving end .
If side = 40 for receiving and to assign the numbers appropriately , was driving side = 20 , it is the speed ratio is 4 2 adjacent side = 40 for receiving the gear ratio 's drive side 10 . Force of progress gear ratio the larger the ratio of the number of teeth of the side that receives the drive side whch is large is reduced. It is that you may be reduced this ratio when the force of progress , such as when climbing a hill want . That's it lol
I 'm the number that is appropriate to the running state torque and speed make the gear ratio make gear changes in the transmission within smoothly in the state N ( neutral) to use the clutch , as I wrote earlier !
Because I become an expert on MT and everyone who has read this and touch mechanism to fine any more you should make to this side mechanism lol
In addition , those that most synchromesh mechanism in MT of modern automobiles have been used .
This is intended to allow to change gear smoothly , helping to reduce the burden on the driver and the like to shift at once . For example, as to be synchronized gently to oblate in different gear reduction ratio , such as the 4-speed from the second , you will see a shift change and comfortably Howan .
Is called a non- synchronous transmission of those not employing the same , and need techniques experienced ( car can much however it is less current ) such as a double clutch , so must tune gently technology yourself when a gear you have become . It comes out in a movie called " Fast and the Furious ".
※ What is clutch? - It is a device for transmitting rotational torque of the engine. It is possible to shut out temporarily the power from the engine When you press the clutch pedal. I will not be performed smoothly become skinny rotational speed of the receiving side and the drive side at the time of gear change and there is no this is no longer fit. Therefore, it is a device very important.

Finally , familiar to everyone , automatic presence of specific smartphone came out , not the Garake . I also called automatic transmission . This is a great transmission that it will automatically changing the gear ratio to match the rotation of the engine and the speed of the vehicle . The biggest advantage would be convenient to me made automatically shift change also . Is not it really useful . There are two methods of typical in AT ( I've never driven car because of only high school student lol) is a continuously variable transmission with automatic transmission and multi-speed transmission with automatic transmission (CVT). Can be divided automatically controlled manual transmission to (AMT) torque converter -type automatic transmission (AT) multi-speed k ... In addition , it is a brief introduction to the torque converter s ... that is installed in almost all the cars AT this time I think it is , and try to explain in some detail the CVT.
A combination (gear that looks as if I circumference of planets around the sun) of planetary gear apparatus and convey the power of the engine with the oil of the torque converter, It is a thing to be speed automatically controlled by hydraulic pressure. It is like a donut, appearance I guess would be close to the old-fashioned. In addition, it has become a cause for the occurrence of phenomena such as "Ganoderma! Advanced car with no and etc. for no stepping on the accelerator" and creep phenomenon torcueconv.... By the way, I use a dedicated oil automatic transmission fluid that (ATF) oil.
Thus, I think I would like to introduce the star of CVT when it was making noise, such as CM, especially a few years ago now. It is the transmission of a very simple structure and very referred to as what they are like, and turn over the belt pulley to (pulley). The engine side, the other is located in the tire side one. It has become a mechanism that can be widely or you can reduce the width of the form in the disk, such as connecting two.
(from Wikipedia)Diameter will increase the diameter of the pulley. It is narrowed to reverse decreases If you increase the width of the pulley .
I wrote about how the transmission at the MT , but it is a smart cookie quite person who rang a bell and indeed to hear how this CVT now lol Because it may be increased gear ratio if you want to slow , it is preferable to increase the diameter of the pulley of the tire side to reduce the diameter of the pulley on the engine side , and is sufficient to reduce the gear ratio if you want to fast it becomes the opposite . Automatic normal has transmission using the magnitude of the gear . In contrast, in order to shift according to the diameter of the pulley , the continuously without any step , CVT I can smooth shift . For example , the engine is too much around in second gear in the automatic normal when going up the hill , but even when the power is too strong this time the rotation of the engine is too low that ... CVT When you select a 3 -speed gear so it is possible that the engine speed is not too high it is possible to produce a shift state as of 2.5 speed , it is possible to exert properly yet , climb comfortably slope . Will it do an excellent Nantes . It is Yutorisedaitoha large difference . Lol
That speed well , easy to exert the engine efficiency is available at all times , without a shock , such as when the gear is switched automatic , can be accelerated smoothly It is advantage of CVT.
But there is also a fact that adoption has not been much in the large displacement cars CVT because it transmits power by the pressure of the belt and pulley . The friction is generated between the belt and pulley , there are a lot of issues with clean lubricant as well as further required , but also take note of the future because it hides the possibility that you can wipe out the problem of AT so far I want to check it.
