Dongfeng Commercial Vehicle AMT, Hydraulic Retarder Gearbox New Product Promotion Seminar
Since May 2018, the DA14 gearbox (automatic transmission) and the DT14 gearbox with integrated hydraulic retarder have been put on the market. In the early trial stage, there have been certain experience customers, in order to further listen to the customer's voice, the total power Chengcheng invited the first batch of verification vehicle customers to conduct in-depth exchanges with Dongfeng commercial vehicle manufacturing, commercial enterprises, R&D and sales personnel to bring greater value and enhance customer experience. At the same time, it will further promote the efficient coordination of new core powertrain R&D, manufacturing, marketing and service, and enhance the product strength of key assemblies, thereby enhancing the value of the whole vehicle.
Participants at the exchange meeting enthusiastically spoke, and everyone was full of praise for the changes brought about by the new products, but why is it easy to use? What are the hidden functions of the whole vehicle? The technical experts at the scene answered the questions patiently.
Reliable project verification
The gearbox development project was officially launched in 2015 and lasted for three years, achieving the first automatic transmission SOP in June 2018.
The design fully considers the complex working conditions, usage environment and user habits of the Chinese truck market, and adapts to the user's various working conditions. The shift selector actuator passed the 2.1 million bench shift test and the life of the B10 reached 1.2 million kilometers.
The vehicle equipped with the DA14 assembly completed road conditions in mountainous areas, hills and plains, as well as high-temperature, high-altitude, alpine environment verification and 1 million-kilometer user test. The index of this automatic transmission has reached the domestic leading position. Level.
Introduction to 14-speed automatic transmission
Dongfeng's self-developed, self-propelled automatic transmission assembly is an Add-on automatic transmission developed on the basis of the Dongfeng 14-speed manual box. The maximum allowable input torque is 2800N·m and the maximum power is 560KW.

3 hidden features are revealed!
1. After a long time of parking, the automatic return to neutral function will stop for a few minutes. Even if the shift lever does not return to the N position, the gear will automatically return to the air, step on the throttle, automatically hang into the starting gear and start; the shift lever does not return to N. After the gear is detected, the gear will automatically return to the air.
2. Neutral coasting function When the vehicle speed is at 10-80Km/h, the throttle is released. After the clutch is opened for 5s, the gear position is returned to the neutral position. When the neutral is sliding, the throttle is stepped on, the auxiliary brake is opened, the brake is applied, and the transmission is geared. Will be put into the appropriate gear.
3, KICKDOWN function throttle to step on the end, the gearbox will downshift to provide power, when the engine speed exceeds 2000rpm, will be upshift; should avoid a large throttle and then loose operation, avoid cyclic shift.
Match 14-speed automatic transmission product advantage
Matching hydraulic retarder gearbox merchandise advantage
After fully understanding the project background, technical features, matching models and sales planning of the two new gearboxes, customer representatives, dealers and suppliers, accompanied by company experts, visited the VT workshop of the powertrain factory.
