Dongfeng Tianlong GX
Dongfeng Commercial Vehicle's Tianlong flagship model has always had an unshakable position in the domestic high-end heavy-duty truck market, with the update and iteration and improvement of the vehicle, Dongfeng launched a truck specifically for trunk logistics, green pass cold chain, express delivery and other high-efficiency working conditions, but also Dongfeng's current highest combat strength of a tractor - Dongfeng Tianlong GX.
North American power chains with excellent performance:
The engine used on the Tianlong GX heavy truck is currently the most powerful Z14 series model in Dongfeng Cummins, which retains the original design of the North American Cummins, with a maximum displacement of 13.48L, a horsepower segment covering 480ps - 600ps, the highest output torque of up to 2750N .m, and the maximum torque speed range of this engine is between 900rpm and 1400rpm, from speed to cruising, can ensure a high torque output.
Dongfeng Tianlong GX engine not only has superior performance, in terms of design and technology is second to none, Dongfeng Cummins Z14 machine through low friction power cylinder, high efficiency supercharger, low intake and exhaust loss camshaft, high thermal efficiency bowl piston and small piezoresistive double thermostat and other 5 innovative fuel saving technology, to ensure ultra-low fuel consumption. The in-cylinder braking technology adopts Cummins' patented technology Inter-brake, which increases the braking power by 25% while significantly reducing vehicle maintenance costs and making it safer and more reliable.
The Denon GX Tractor incorporates automatic gearing into the standard, and its matching gearbox is the Winning AMT Series 12-speed automatic transmission from Eaton Cummins. The structure of this transmission is an overspeed gear structure with a maximum gear ratio of 0.77 and a maximum input torque of 2750 N.m. The box adopts dual intermediate shaft, full synchronizer and silent helical design, and the oil change interval can reach 600,000 kilometers, which comprehensively improves the gear life and extends the transmission time. On this gearbox is also equipped with an intelligent shift system, which can shift gears according to whether the car is in a ramp, how much weight the car weighs, engine torque and the current throttle opening, and can also be "jumped" like manual operation, and it also has a variety of driving modes to choose from, adaptability and maneuverability are greatly enhanced.
Tianlong GX can also be equipped with Voith's hydraulic retarder, which is connected in parallel at the rear of the gearbox, which can provide continuous braking to achieve the effect of slowing down the speed of the car during long downhills, avoid the phenomenon of overheating of the brakes, reduce the driving danger, and engage in the Yunnan-Guichuan special line is very suitable.
The front and rear axles of the vehicle are Dongfeng Dana Bridge, and the rear drive axle is a 13-ton single-stage deceleration bridge with axle speed ratio of 3.08, with transverse stabilizer bar and longitudinal stabilizer bar, and the brake uses ventilated disc brakes.
So the whole vehicle power chain is Dongkang Z14 high horsepower engine + win AMT transmission (speed gear) + Dana 3.08 speed ratio rear axle, this set of power combination in the economic speed is very dominant, from 80km / h - 112km / h are economic speed, in line with the needs of efficient and express vehicles.

And the circulating oil lubrication structure can also cool the bearings, which is very suitable for long-distance trunk vehicles.
All wheel rims use aluminum alloy rims, which can reduce the self-weight by about 150kg compared to traditional steel rims, and the heat dissipation of aluminum alloy rims on disc brakes is also slightly effective.
Tianlong GX's 4X2 chassis is a long wheelbase specification, so the layout of the fuel tank can be appropriately increased, in order to ensure that long-distance trunk logistics can have a good endurance, Tianlong GX tractor on both sides of the girder set up an aluminum alloy fuel tank, the total capacity of up to 1250L, most of the long-distance lines in the case of full oil do not need to be replenished.
The chassis layout is compact, in order to improve the utilization of space, dongfeng Tianlong GX's urea storage tank is arranged above the fuel tank, using an aluminum alloy platform for fixing.
The suspension of the vehicle is a combination of the first 2 pieces of steel plate + the rear 4 airbags, in addition to the basic shock absorption effect, there is also electronic control technology from Knorr-Bremse, which can adjust the height of the airbags arbitrarily, suitable for connecting trailers, platforms and other scenarios, which greatly reduces the difficulty of hanging transportation and makes the operation more efficient.
The stunning appearance of the same color body is lovely:
From the earliest Tianlong flagship to the current Tianlong GX, the appearance is always so stunning at first sight, and the all-white body color matching adds a bit of nobility and elegance to this car, and the visual effect is comparable to the top-class modified heavy truck in Europe. On Tianlong GX, users can also choose the "Canglong Qing" color, which is also a main color number, and the visual effect is equally shocking.
The configuration of the headlights should be relatively ceiling-level, Tianlong GX uses a main lighting lamp of xenon headlights + dual lenses, and the illumination of far and near lights has been greatly improved, and the best lighting effect can be obtained in different environments. The vehicle's turn signals and daytime running lights are LED light sources, and there will be a running water effect when the turn signals are turned on.
On the side of its body, there is a dragon pulling flower, which echoes the angle of the side window line, and of course symbolizes that the Tianlong GX has a noble and honorable identity like a dragon.
