Longqing DT14 gearbox is the second generation of heavy-duty multi-speed gearbox in the industry. It has the characteristics of high reliability, high transmission efficiency, super strong load-bearing capacity, light weight, small speed ratio difference, etc. It is suitable for heavy-duty traction, engineering, cargo and other vehicles.

Reliability

DT14 adopts full helical gear + planetary auxiliary box structure, with low noise and strong load-bearing capacity. The synchronizer friction material has the leading domestic ability in terms of pressure resistance and overheat resistance.

Convenience

Single H double switch operation principle, clear gear position, convenient operation, self-amplifying double cone synchronizer, the shifting force is 2-3 times less than the synchronizer of the same level, the shifting is easier, and the feel is like a family car;

High efficiency

The dual lubrication method of active lubrication + splash lubrication is used to lubricate key parts such as bearings, synchronizers, and gears, which ensures more complete lubrication and lower friction losses. An independent external oil cooling system is used to avoid the problem of excessive temperature of the transmission assembly under special road conditions (climbing long slopes), ensuring stable operation of components and higher transmission efficiency, while extending the oil change mileage and transmission service life.
