從自動變速箱的發(fā)展來看，優(yōu)化傳動效率、減少動力損失的一部分工作則會在液力變矩器部分進行。比如增設的單向鎖止離合器可使動力的傳遞由原先的液力傳遞過渡為硬性連接，從而減少動力的損失，當然，這是在保證行駛舒適性的前提下進行的。
From the development of automatic transmission, part of the work of optimizing transmission efficiency and reducing power loss will be carried out in the hydraulic torque converter. For example, the additional one-way lock up clutch can make the power transmission transition from the original hydraulic transmission to hard connection, so as to reduce the power loss. Of course, this is carried out on the premise of ensuring driving comfort.
改變齒比的工作由行星齒輪機構(gòu)完成，通過改變太陽輪、行星輪以及齒圈之間相互的運動關(guān)系可實現(xiàn)不同傳動齒比的切換，從而在不同的車速以及駕駛路況的情況下選擇適合的擋位行駛。
The work of changing the gear ratio is completed by the planetary gear mechanism. By changing the movement relationship between the sun gear, the planetary gear and the ring gear, the switching of different transmission gear ratios can be realized, so as to select the appropriate gear for driving at different speeds and driving conditions.
液壓控制系統(tǒng)以及電子控制系統(tǒng)則是負責統(tǒng)籌換擋進程的關(guān)鍵，電子控制系統(tǒng)就像人的大腦，在接收到來自發(fā)動機、輪速的信息后，通過計算并下達換擋指令，而液壓控制系統(tǒng)則好比人的神經(jīng)，將大腦發(fā)出的指示傳遞至相應部位并使其動作，為典型的要屬在換擋時，行星齒輪機構(gòu)的變化以及內(nèi)部離合器的控制。
The hydraulic control system and the electronic control system are the key to the overall planning of the shift process. The electronic control system is like a human brain. After receiving the information from the engine and wheel speed, it calculates and issues shift instructions. The hydraulic control system is like a human nerve, which transmits the instructions sent by the brain to the corresponding parts and makes them act. It is a typical shift, Change of planetary gear mechanism and control of internal clutch.
In addition, Jinan automatic transmission maintenance personnel believe that we should also understand the advantages of the transmission itself, such as:
1、油耗更低。由于增加了檔位，使得變速器的齒比更密，這樣可以讓車輛在更合理的檔位行駛，降低發(fā)動機轉(zhuǎn)速，從而減少燃油消耗。
1. Lower fuel consumption. As the gear is increased, the gear ratio of the transmission is denser, which can make the vehicle drive in a more reasonable gear, reduce the engine speed and reduce fuel consumption.
2、加速更快。自動變速箱因為有了更高的整體齒輪比，從而提高了自身的加速度值。
2. Faster acceleration. The automatic transmission has a higher overall gear ratio, which improves its own acceleration value.
3、承受更高的扭矩。變速箱可謂是集輕型元件與革新性齒輪組理念于一身的新式變速箱，另外其增加的兩個齒輪可傳輸更大的扭矩，同時具有元件更少且重量不變的特點。
3. Withstand higher torque. The gearbox can be described as a new type of gearbox integrating light components and innovative gear set concept. In addition, the two additional gears can transmit greater torque. At the same time, it has the characteristics of fewer components and constant weight.
4、更低阻力損失以及更高的機動效率。所攜的的四個齒輪組只有五個換檔元件，每次換檔時只打開其中兩個元件，而且與軸向平行的新滑片泵可提高傳動效率，能量損失降至很低水平。
4. Lower drag losses and higher maneuver efficiency. The four gear sets carried only have five shift elements, and only two of them are opened during each shift. Moreover, the new sliding vane pump parallel to the axial direction can improve the transmission efficiency and reduce the energy loss to a very low level.
