The output shaft of the power is also different. One output shaft realizes the power output at the low speed, the other shaft realizes the power output of the high speed and the reverse gear, and the power of the two output shafts is linked with the final output shaft of the transmission. Together, the power is delivered to the wheels. In addition, the conventional arrangement is not used in the arrangement of the shifting gear sets. The shifting gears are not arranged in the order of the gear positions, so that the gears of the adjacent two gears are arranged. There will be no more sharing of a synchronizer, which provides a technical guarantee for seamless delivery of power. The structural arrangement is shown in Figure 5. work process When the car is hung up in the first gear, the clutch 1 that controls the odd gear input is turned on, so that the solid input shaft connected to the odd gear is rotated, and the first gear synchronizer automatically meshes with the first gear on the low speed output shaft to realize the low speed. The output shaft of the gear is linked. The power transmission path is shown by the solid line and the arrow in Fig. 6(a). At the end of the low speed output shaft, there is a helical gear, and the helical gear is used to output the power to the differential and then to the final output shaft. While the first-speed synchronizer and the first-speed gear are engaged, the two-speed synchronizer is also engaged with the second-speed gear under the control of the electronic control component, and is in a work standby state. Looking at the power transmission route of the second gear, when the transmission is engaged in the first gear, the clutch 2 that controls the even gear input shaft is separated, and thus is in a state of being completely disconnected from the engine power, as shown in Fig. 6(a). The line indicated by the dotted line and the arrow. At this time, the sleeve (hollow) input shaft connected to the even gear is rotated by the second gear, but it is completely rotated by the gears following other odd gears. The output of the power is only prepared for the next upshift. Therefore, the input shaft of the even gear will not interfere with the power of the odd gear input shaft, and the output shaft of the high gear will follow the rotation, but it is also in the idling state, without any power output, so there is no power output. Any power interferes with each other. When the transmission enters the 2nd gear, when the first gear is stepped out and the first gear is released, the clutch 2 is connected, and the 2nd gear is hung as shown by the solid line and the arrow in Fig. 6(b). At the same time, the 3rd gear is pre-combined. As indicated by the dashed lines and the arrows in Fig. 6(b), the continuous operation is such that the transmission has no gap at all when it is engaged and unlocked. Therefore, in the working process of the DCT transmission, there are always two gears combined, one is working, and the other is ready for the next step. The clutch that controls the even-numbered gear is combined with the power output end of the engine under the control of the electronic control unit, and the clutch that controls the odd-numbered input shaft is disconnected from the output end of the engine, thereby completing the power switching of the input shaft, in the process, The two clutches are fully synchronized, and no longer have a power interruption when the clutch is disconnected from the power output of the engine, as in a conventional single clutch transmission. At the same time that the second-speed power switching is completed, the third-speed synchronizer is also meshed with the third-speed shifting gear box under the control of the electronic control unit, so that the third-speed transmission gear is in a standby state. In addition to the upshift, the DSG will make the higher gear position outside the standby state. In the overspeed mode, it can also achieve the standby state for the downshift and speed up the downshift time. Analysis of the prospects of DCT in the domestic market Since the DCT is based on the development of a parallel-shaft manual transmission, it inherits the advantages of high transmission efficiency, compact installation space, light weight and low price, as well as automatic transmission start and shift quality. Characteristics, with broad development prospects and significant advantages in promotion and application, mainly in the following aspects: DCT is almost independent of the transfer power and can be widely used in various vehicles. The production cost of DCT is low. Since DCT is based on the development of manual transmission, power transmission still relies on clutches and gears. At the end of complexity, domestic gear transmission parts manufacturing technology is relatively mature, and most transmission manufacturers have a certain technical foundation. Provided conditions for the development of DCT technology. The production unit of DCT can be used by slightly modifying the existing manual transmission transmission line. Therefore, the manual upgrade process has a short period of new product upgrade process and less investment inheritance. Due to the wide range of transmission requirements, the application of DCT technology (gear transmission technology + automatic control technology) will not only be limited to automotive transmissions, but also in other transportation machinery industries. China's automobile industry started late, and the production line at this stage is mainly based on the production of manual transmissions. In the high-growth period of automatic transmissions, the automatic transmissions of domestically produced vehicles are mainly relying on imports, so the development of DCT products is improving China. The independent development capability of automatic transmissions will certainly have a positive impact. At the same time, it is also compatible with China's industrial base.
