　　　 [XCAR Information Original]　

　　　　As we all know, engine, gearbox and chassis are the three key components of an automobile, and they are also the core technologies that a vehicle manufacturer must master. In the last article, we talked about the achievements of independent brands in engine research and development. In the early stage, independent manufacturers mostly used imitation and purchase to obtain engine technology. Compared with engines, the lack of self-owned brands in automatic gearbox technology is more obvious. The research and development of automatic gearbox is difficult, with high technical content, and it is difficult to imitate in a short period of time, which makes it impossible for self-owned brands to develop automatic gearboxes that can be applied on a large scale at present.

Technical blockade! Automatic gearbox inventory of dozens of autonomous vehicles

　　　　There is a great demand for automatic gearbox in the market, and the demand is still growing, which makes independent brands can only obtain automatic gearbox by purchasing. However, the lack of their own technology and the restrictions of foreign gearbox manufacturers also lead to the limited choice of automatic gearbox for independent brands, and most of the products they carry do not have much technical advantage. Today, what we are going to introduce to you are several automatic gearboxes that are common in our own brand models.

　　　● AT gearbox

　　　　Manual gearbox is mainly composed of gears and shafts, which produce variable speed and torque through different gear combinations; The automatic gearbox AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, which realizes variable speed and torque by means of hydraulic transmission and gear combination.

　　　　Hydraulic torque converter is the most characteristic component of AT gearbox, which is composed of pump wheel, turbine and guide wheel, and directly inputs engine power to transmit torque and clutch action. Pump wheel and turbine are a pair of working combinations, which are like two fans placed opposite each other. The wind from one active fan will drive the blades of the other passive fan to rotate, and the flowing air — — Wind becomes the medium of kinetic energy transfer.

　
Hydraulic torque converter of conventional automatic gearbox

　　　　If air is replaced by liquid as the medium to transfer kinetic energy, the pump wheel will drive the turbine to rotate through the liquid, and then a guide wheel is added between the pump wheel and the turbine to improve the transfer efficiency of the liquid. Because the range of automatic speed change and torque change of hydraulic torque converter is not large enough and the efficiency is low, several rows of planetary gears are connected in series behind the turbine to improve the efficiency, and the hydraulic control system will automatically control the planetary gears with the change of engine work, thus realizing automatic gear shift.

　　　　Self-owned brand AT gearbox provider 1: Aisin Seiki

　　　　Manufacturer profile:Japan Aisin Seiki Co., Ltd. is one of the world’s top 500 enterprises and the ninth largest auto parts manufacturer in the world. Founded in 1949, the company is the main supplier of Toyota auto parts, and its auto parts manufacturing technology is world-famous.

Other AT gearbox suppliers

　　　●　continuously variable transmission

　　　　CVT has no specific gear, and its operation is similar to that of automatic gearbox, but the change of speed ratio is different from the trip stop process of automatic gearbox, but continuous, so the power transmission is continuous and smooth.

　　　　The advantages of CVT are as follows: First, the power output of CVT gearbox is linear, and the shifting frustration caused by it also disappears, which is very smooth in actual driving. Secondly, the transmission system of CVT can have infinitely many gears in theory, and the gear ratio, speed ratio and the balance of performance, fuel consumption and exhaust emission in the traditional transmission system are easier to achieve. Finally, the mechanical efficiency and fuel economy of CVT transmission are much better than ordinary automatic transmission, second only to manual transmission, and the fuel economy is much better.

continuously variable transmission

　　　　So CVT has no shortcomings? The answer is no, first of all, when starting or accelerating, CVT steel belt or belt is prone to slip, which will affect the power transmission, thus affecting the acceleration feeling. Secondly, CVT steel belt or belt material requirements are relatively high. Although CVT has a simple structure, if it fails, it is generally not a minor problem. This will affect the use of car owners and increase maintenance costs.

Self-owned brand models equipped with CVT gearbox

　　　　●AMT gearbox

　　　　Automatic mechanical transmission (AMT) is a new type of transmission that electronically controls the traditional dry clutch and manual gear transmission to realize automatic shifting, and its control process basically simulates the driver’s operation. According to the driver’s intention, the electronic control part of AMT gearbox can automatically control the clutch and shift process. More complicated, we don’t need to go into details. In fact, we can imagine the shift process of AMT in this way. His clutch and shift mechanism are controlled by electronic parts, and the shift will be automatic naturally.

　
Electric control device and hydraulic actuator of AMT

　　　　The biggest advantage of AMT gearbox is that it does not need to make too much changes to the existing manual gearbox, and its technical structure is relatively simple, and the cost is not too high for manufacturers. In fact, AMT is a manual gearbox with electronically controlled clutch and shift program, so it is the same dry clutch as manual transmission, so the transmission force is more direct and the fuel consumption is more economical. The ordinary AT gearbox adopts hydraulic "clutch", which will have some losses in energy transmission and slightly higher fuel consumption.

AMT is somewhat similar to an automatic manual transmission.

　　　　Of course, AMT has obvious shortcomings, that is, the shift quality is not high and it is prone to frustration. If you don’t step on the accelerator, the car won’t move forward even if you shift into D gear. This is somewhat different from the ordinary AT gearbox.

　　　　AMT gearbox supplier: Ma Ruili.
