All of a sudden mastering Fast (AT) AT transmission

On December 8th, 2014, Xi'an Shuangte Intelligent Transmission Co., Ltd. held a Fast Test Test Drive at the high-tech plant of Xi'an Hi-tech Factory. activity. Let the intimate Xiao Bian below to introduce to you what the Fast special AT transmission is worth showing and recommending.

Fast (AT) AT transmission model naming rules

According to the China Truck Network reporter, Xi'an Shuangte's 6-speed heavy-duty automatic transmission is up to the international advanced level. Its main products are FC6A80/100, FC6A140/180, and FC6A/210/250, which can be widely used in 600N torque. · M---3000N·m city vehicles, terminal tractors, mining dump trucks, luxury buses, and special vehicles.

Faster (Shuangte) Transmission Nomenclature

First of all, let's take a look at the naming rules of the product model. From the above figure, we can easily see that FC is an acronym for FAST and Caterpillar, and 6 for the forward gear. The number, A, stands for a hydraulic automatic transmission, and the number behind it is multiplied by ten as the maximum output torque.

Make commercial vehicle driving easier

I believe that many friends who have driven a car can appreciate the difference between AT (automatic transmission) and MT (manual transmission). MT needs us to shift gears according to different road conditions, especially in places where the city traffic is relatively heavy, and the MT transmission The car is a headache for many novices, but AT is different, easy to operate, easy to control the speed of the throttle, easy to learn. Commercial vehicles are actually very similar. For long-distance drivers, the skilled control of the levers can be said to be very important, but some trucks have 12 or more stalls. We only hear so many stalls. Feeling very troublesome, not to mention the actual operation of the driver friends.

The Fast (AT) AT transmission solves this problem for the driver's friends. The biggest difference is that the torque converter replaces the traditional clutch. The main box adopts a planetary gear structure and can also provide more torque. , The torque that can be reached by manual 12 gear generally, can be realized as long as 6 gears on AT gearbox, it is more easy to operate, the shift is more quick and smooth, even novice can also be familiar with.

Unique rear power take-off

The biggest characteristic of the Fast (AT) AT transmission is that it uses a unique rear-mounted power take-off device. Different power take-off positions and different power take-off gears have different speeds. The power take-off is generally divided into front. Positioning, side mounting, rear mounting, and front mounting are widely used for auxiliary power devices with high power requirements, while the side-mounted applications are relatively small, and are used in some less demanding models, and the rear power take-off With the most advantages, it can not only effectively reduce the size of the transmission, improve fuel economy and work efficiency, but also improve the acceleration performance and load capacity of the truck. However, the requirements for design are particularly high. A transmission equipped with a rear power take-off can be called The highest level in the heavy-duty transmission.

After a detailed introduction by Xiao Bian, whether or not everyone suddenly understood the unique charm of the Fast (AT) AT transmission, its emergence can be said to achieve a major breakthrough in domestic heavy-duty hydraulic transmission, and also to break the long-term dependence of domestic automatic transmissions. The passive situation of imports.
