As a relatively small car manufacturer, Mazda has always adhered to its own philosophy and created its own signature with its ingenious design and Chuangchi Blue Sky engine technology. Since Mazda positions itself as a manufacturer with leading technology, in addition to Chuangchi Blue Sky Technology, which is in charge of the engine, its accomplishments in gearboxes are also very outstanding.
Mazda’s 6AT gearbox is said to have the ability to allow drivers to “unify men and women” and enjoy the joy of driving, from the A-class Envision Sera to the B-class Atez, and even in the middle class. The CX-8, a large SUV, has a very good sense of control.
Even if some large groups face gearbox ramping problems, they are easily in trouble. As a small car company, Mazda has difficulty matching the size of some large companies due to its capital, patents, personnel and other reasons. However, Mazda is able to create different levels and types of transmissions in its own right that are comparable to those launched by major manufacturers.
Mazda’s 6AT gearbox, internally coded as FW6A-EL (horizontal 6AT), is a gearbox independently developed, designed and produced by Mazda. After test driving Mazda's models, many fans believe that Mazda's transmission is ahead of its class. So how good is the Mazda transmission?
First of all, in the structure of the Mazda 6AT gearbox, a transmission scheme consisting of two sets of Simpson planetary gears is used, combined with three free planetary mechanisms composed of three brakes and two clutches, through decoupling Achieve six forward gears. There are many similarities in the overall structure and layout of Mazda 6's AT gearbox and Toyota's A761E gearbox, so many senior car fans think that Mazda's 6AT gearbox is a special version of Aisin's 6AT gearbox, but this The point of view is actually very one-sided.
There is a fundamental difference between the 6AT gearboxes launched by the two manufacturers. The most significant difference is that the Toyota A761E gearbox is vertical, while the Mazda FW6A-EL is horizontal. Moreover, Mazda's FW6A-EL gearbox and Toyota's A761E gearbox are very different in structural design (the transmission method of the Aisin transverse 6AT gearbox is Repala's Czech planetary gear structure) and component arrangement, so the two The gearbox actually doesn't matter much.
Mazda’s 6AT gearbox is very unique in its overall mechanical design. It adopts the flat-plate hydraulic torque converter produced by Esidi. Even if three rows of stars, three brakes and a complete brake hydraulic system are incorporated into the gearbox, the radial controllability of the gearbox volume can be guaranteed, but it takes up more empty space inside the engine. Matched with a multi-disc locking clutch, the process is simpler, the structure is simpler than the Leplet type, and the efficiency is higher, making the locking range of the entire planetary gear set as high as 89. During the power transmission process, the contact and transmission of gears become more direct, and the damping performance is stronger, improving the transmission efficiency and response performance of the gearbox.
If we talk about the shortcomings of the AT gearbox in Mazda 6, then there are many layers of sleeve shafts in the center of the gearbox, which requires very high processing and assembly requirements for the manufacturer. Of course, when it comes to the production of gearboxes, there is no love letter from OMG (Mazda has two gearbox factories in Wuhan, Thailand and Fufang, Japan).
Mazda’s gearbox is different from the Aisin 6AT gearbox in its overall structure. Although it is a horizontal 6AT gearbox and has many competitors in the market, Mazda's 6AT gearbox has made a lot of efforts in setting the transmission ratio to meet the performance requirements of different models and enhance the competitiveness of its own brands in the market. .
In the gearbox design process, in addition to improving the hardware foundation of the gearbox, Mazda is also good at adjusting the TCU of the gearbox. In the process of adjusting this gearbox, Mazda must not only consider the mechanical quality of the gearbox itself, but also consider the different displacement engines and different models that need to be matched.
(Except for the Mazda MX5, which uses longitudinal rear drive, Mazda has no intention of developing a gearbox for this model, so it uses an Aisin longitudinal 6AT gearbox);
It adds a TCM self-learning function. This allows Mazda's gearbox to realize the idea of ??"male and female integration", that is, to collect the driver's driving habits, control data, etc. Through the self-learning module, the transmission can be optimized to change the shifting logic of the transmission, so that the upshifting of the transmission is closer to the driver's driving habits, allowing consumers to enjoy the fun of driving. This is a feature that other models of the same price and level currently on the market do not have, and it is also the reason why Mazda transmissions are highly praised in the market.
To sum up, Mazda’s FW6A-EL gearbox allows drivers to Feel the unique charm of the naturally aspirated engine, and at the same time let consumers know that even a senior B-class car like the Atez has impressive driving and control fun.
