Has been mass produced! Dongfeng DT14 manual gearbox parallel Voith hydraulic retarder

"On January 6, 2019, 15 transmissions with integrated hydraulic retarders were dispatched, 40 on January 7, 2019, 30 on January 9, 2019, and 20 on January 10, 2019..." On January 6, 2019, Li Yang, the production management division planner of Dongfeng Commercial Vehicle Company's powertrain factory, immediately received the customer's order and immediately organized the VT workshop assembly line to carry out production and prepare materials in advance. The intensive order mark marks the new gearbox gradually entering the mass production phase.

DT14 manual gearbox

It is understood that the gearbox of this integrated hydraulic retarder is the DT14 manual gearbox parallel to the Voith hydraulic retarder , mainly equipped with Dongfeng Tianlong series heavy truck to enhance the power, climbing strength and safety of the series. force. From the 3rd of January, the gearbox gradually ushered in a small climax, with 187 units scheduled for the first week.

New gearbox ready to go

The gearbox is still the gearbox, but the DT14 gearbox with the hydraulic retarder is the downhill artifact! Why do you say that?

As we all know, heavy trucks are frequently braked on highways or long downhill sections of mountain roads. The frequent friction between brake pads and brake discs will generate huge heat. When “heat decay” occurs, the vehicles will easily stall and get out of control.

The DT14 gearbox with the hydraulic retarder is the downhill artifact

For a long time, the domestic heavy-duty truck driver should respond to the overheating of the brake disc caused by continuous braking, that is, install a water sprinkler and use the brake disc to pour water to physically cool the brake disc. The addition of the hydraulic retarder can better solve the brake failure phenomenon when the slope is long, and the driver can even realize the downhill without stepping on the brake.

VOITH hydraulic retarder

Performance parameters of Voith hydraulic retarder

In the match with the whole vehicle, the powertrain factory and Voith also made great efforts to ensure that the data meet the design requirements and driving needs. At present, the DT14 gearbox with integrated hydraulic retarder has been market-proven and entered the mass loading phase.
