At the beginning of the year, QJMOTOR unveiled the much-talked-about "Flash 300 automatic transmission version", which attracted enthusiastic reports and attention from many media. Recently, Xiaobian got some new news about QJ-automatic transmission, you might as well learn about it first.
QJ-Automatic Transmission Technology
For the first time, QJMOTOR has adopted a technology called QJ-automatic transmission on the flash 300 model, which is an automatic transmission technology developed specifically for motorcycles, which should be designed using a principle similar to that of an AMT automatic transmission. Although the AMT transmission is a kind of automatic transmission, it can also be called an automatic manual transmission, and it is an automatic transmission based on the manual transmission, which is an automatic transmission with upgraded technology.
According to the information currently available, the QJ-automatic transmission equipped with the flash 300 automatic transmission replaces some operations of the traditional manual transmission with the TCU controller, electric shift actuator and clutch actuator, so as to achieve the purpose of automatic shifting. Through the cooperation between the TCU controller and the clutch and shift actuators, this system simulates the gear shift action of the motorcycle we usually operate, while also retaining the function of manual gear shifting.
1. The traditional gear shift lever is replaced by a gear selection mechanism driven by a motor, which is composed of a drive motor, a reduction gear mechanism and a drive output end, and is installed at the position where the traditional gear lever is connected with the engine. This mechanism can completely replace the operation of the shift lever controlled by the feet of a real person, and the motor drive will respond faster, only 0.3 seconds to complete the shift operation, no mud and water, and no misoperation.
2. The traditional clutch pull rod is replaced by the clutch actuator, which is composed of motor, transmission rack mechanism and drive output end, and the whole structure is installed above the clutch side cover, and also completely replaces the traditional clutch cable. Under the control of the TCU, this structure will accurately control the timing of the clutch cutting and disengagement, and complete the clutch's clutching/closing action.
3. ECU we all know is to control the ignition, fuel injection and temperature control of the engine, and many friends of the TCU controller have not heard of it, in fact, TCU (Transmission Control Unit) is the control unit of the automatic transmission, that is, the core center of the entire automatic transmission gearbox, responsible for controlling the decision-making and execution of the entire automatic transmission system, which is equivalent to replacing our human brain to give orders to the entire set of gear shifting actions.
QJMOTOR's automatic transmission, although the traditional shift pedal and clutch lever have been canceled, have not lost the function of manual shifting. If you want to manually change gears, you can use the new paddles next to the handlebar buttons, and you can switch back and forth between automatic and manual shifts at will, and enjoy the comfort brought by the "automatic hand" gearbox.
How fragrant an automatic transmission motorcycle is
Whether it is in the automobile circle or in the motorcycle circle, we can often hear old drivers complain about automatic transmission, which roughly means that automatic transmission has lost the fun of control. But there must be two sides to everything, many people only see the fun of automatic transmission, and ignore the huge advantages of not having to change gears, and now the automotive industry in the automatic transmission occupies the mainstream, manual transmission is reduced to a niche is enough to explain the problem. In the motorcycle circle, for novices, the attraction of automatic transmission models will actually be greater, and automatic transmission models will be more fragrant, don't believe you look down.
First of all, because the shift pedal and rear brake pedal are eliminated, the area of the driver's pedal can also be made wider and more comfortable, which greatly improves the comfort of riding. Of course, this is only a small aspect, and you can see that without the gear lever, not only is it easier to operate, but also there is more room for feet.
Then, the friends who often ride motorcycles are very clear that international motorcycles need to be "hooked" operation, that is to say, they need to be upshifted like the picture above, so many shoes will also be dyed black and dented, especially white shoes and light-colored shoes. For this reason, many riders dare not wear too expensive shoes to ride, indeed because they are too wasteful. For riders who don't like to wear cycling shoes to go out, and even for riders who like to wear light-colored shoes, the design without a gear lever solves a major pain point, and completely saves the "little white shoes", and there is no need to worry about what shoes to wear when riding a bicycle in the future.
In addition, for novices, the biggest problem facing the gear bike is the oil/departure coordination, and it is because of this that many people give up their motorcycle dreams. The benefits of automatic transmission at this time are apparent, just give the oil and go, no need to worry about stalling, ride a motorcycle by riding an electric car, directly eliminate the threshold of the gear car, and the motorcycle dream is close at hand.
Then, another advantage of not changing gears is that it can greatly solve the misoperation caused by the unskilled operation of novices, including the wrong timing of gear shifting, the dead fire situation caused by poor throttle control, and even the misuse of neutral gear and clutch, resulting in the loss of engine braking power, and then because of poor brake control, resulting in crashes, in-situ reversing accidents. In other words, this automatic transmission transmission can also bring a function similar to "hill descent", which improves the sense of safety.
At the same time, the improvement of riding comfort without changing gears is also very obvious, whether it is in the daily city commute or in the process of long-distance cycling. Whether it is a congested street or a frequent traffic light, it is necessary to shift gears back and forth, which will inevitably lead to sore hands and feet, which greatly reduces the operation steps of cycling, and can really make riding a kind of enjoyment.
Automatic transmission may become a trend
Although the biggest pain point of the current flash 300 automatic transmission cruise model is actually to solve the problem of novice riding difficulty, with the maturity and advancement of technology, automatic transmission is also expected to appear in various displacements and various types of models. QJMOTOR may also gradually form a new "automatic" model series, and automatic transmission motorcycle will also become a new trend in the development of the industry.
