High transmission efficiency and long oil change interval, saving money and being free from worry. The use of forced lubrication and low friction coefficient bearings makes the transmission efficiency increase by more than 1% compared with the previous generation products. At the same time, the special fully synthetic lubricant, no need for first warranty, oil change intervals up to 800,000 km under road application. "Smart"! TCU integrates slope sensor, which can sense the slope and calculate the vehicle weight intelligently, making the gear shift more intelligent and adaptable. Meanwhile, with the upcoming new generation TCU, it can realize full-function UDS diagnosis, OTA program online upgrade, ISO26262 functional safety and other functions.

Application

It can cover 22t-55t for regional transportation, urban construction, port traction, in-plant reverse short and other scenario applications.
