Product Description:

Adopting 6×2driving type, equipped with Weichai WP10 series diesel engine with High-pressure & Common rail with 336PS, various models of FAST gearbox, Pengxiang 6.5T 457 dual front axle & Hande single/double reduction rear axle, Dayun tractor truck CGC4222 achieves domestic first-class level and also enjoys comfort of Euro-type cab.


1、European driving cab
The European large cab is ergonomically designed and comfortable. It enables the cab to bear over 50% impact by means of
adopting all-metal frame, bird's nest structure design, domestic pioneering energy-absorbing bumper and four-point suspension structure. The designs all enable the cab’s safety and comfort.

2、Spacious and comfortable sleeper design
Spacious sleeper in the cab and thickened sleeper pad enable the cab to be more comfortable for rest. Good sleeper fabric
texture makes it more dirt resistant and durable. The fixing structure of upper bunk becomes more reasonable, the sleeper support and safety protection device are increased and the fixed mode of the sleeper sunshade is also improved.

3、Multi-bit precise-controlled instrument panel
An adjustable LED five-level circulation background lamp is used. The indicator indicates precise reading and self-testing
can guarantee smooth operation.

4、Automatic Cruise Control System
The user can freely set driving speed and keep driving at fixed speed. The intelligent setting can reduce oil consumption
and enhance driving stability.


1、Weichai Power
Weichai engine is designed with the new bypass valve pressurizer, to improve the working efficiency under low speed. The
new engine can increase the low-speed torque by about 12% and reduce the oil consumption by 10%-15% with the oil calibration of the oil spraying pump in the low-speed area. Weichai engine has reliable quality and long lifetime, which make driving more comfortable in effective and economical way.

2、Hande axle
Shaanxi Hande axles are fully optimized. The axle housing is completely thickened and its work section height is increased.
A new quenching technology is applied to the whole half housing, so the whole bending-resistance capability of the driving axle is improved by about 30%. The new quenching technology can enhance gear strength and eliminate possible gear collision.

3、Fast gearbox
Equipped with the heavy automobile transmission which applied American Eaton technology from Shaanxi Fast. Its novel and
advanced design eases gear switching and also improves the bearing capability which is more stable than its predecessor.

4、Drive shaft with Benz technology
The optimized Benz commercial car drive shaft improves the gear shape of the spline and strengthens the gear root. The
sliding fork is upgraded and improved. The spline shaft is optimized to match the spline cover. The new end gear drive improves bearing on the connection flange. The new nylon painting technology improves the bearing status of the working drive shaft, reduces drive impact and completely reduces internal wearing loss.

Dayun automobile is equipped with the equal-work section and high-break work section twist-resisting and bending-resisting frame. The bending-resisting capability of the truck’s longitudinal beam and round girder is also strengthened by using the Stery technology.

Q:Traction brake system
When the brake pedal is disconnected, the micro switch control circuit, brake lights, the brake cable brake drum brake shoe with the brakes, and vehicle braking. Release the pedal, the motor control circuit is switched on, and the brake shoe is contracted. At this time, if the accelerator pedal is lowered, the vehicle can walk.
Q:What are the criteria for heavy vehicle classification?
Heavy duty vehicles: class M and class N vehicles with a maximum mass greater than 3500Kg. An automobile train consisting of a heavy tractor and a heavy trailer. Large cargo for carrying size and weight over highway traffic regulations.
Q:Is the hang (all - or - half) car behind the tractor capable of driving?
In front of the driving ability of the front is called a tractor, there is no traction behind the ability to drive vehicles called trailers, trailers are towed by tractor. There are two kinds of connection mode of the tractor and the trailer: the first one is the front half of a trailer traction saddle in the tractor rear section on the top of the back of the car bridge under traction Trailer part weight, which is half hanging; second is the front end of the tractor trailer even the rear of the towing vehicle only provide forward force, dragging the trailer go, but does not bear the weight down trailer, this is the whole hanging. But no matter hanging or hanging, trailers are not driving capacity. Electric vehicle engine via a clutch transmission drive shaft, finally transmitted to the drive axle around again assigned half shaft drive wheel, power transmission, in this way, the drive axle is the final assembly of the utility model is mainly composed of reducer and differential.
Q:Which is the main drive of the dual drive tractor?
Specific depends on what kind of model you buy, and different models of torque output is different (engine torque is the engine output torque from the crankshaft end. Under the condition of fixed power and engine speed is inversely proportional to the speed, the faster the torque is small, and vice versa. It reflects the load capacity of the automobile within a certain range, with high speed and low speed, high speed and low speed running fast, running slow. )
Q:What's the difference between a large truck and a tractor?
The truck, truck needs, so with hopper, is a whole.Tractors are tow goods. They can be goods shelves, cargo racks, cylinder racks, etc.. A mechanical device that provides power only and does not have the goods in place.
Q:Germany X3000 6*2 tractor sleeper Longxin widened 430 horsepower and 480 horsepower, which do not take the high-speed fuel, which to buy
In fact, this is not absolute, generally speaking: to avoid long engine idling, as far as possible to avoid the emergency brake. Reasonable use of high and low gear, to maintain the proper speed. Generally speaking, at the speed of 88.5 kilometers per hour, the most fuel-efficient, speed increased to 105 kilometers per hour, fuel consumption will increase by 15%, while 110 to 120 kilometers per hour will increase by 25%. Keep the vehicle low wind resistance, try not to load on the roof or make improper alterations.
Q:Why are big horsepower tractors all 6*4?
But considering the length of the transmission shaft, and the differential problem, 6 x 4 horsepower is large, but with the improvement in technology, in recent years China out of the new, improved bridge 6 x 2, 440480 or even 540 is also equipped with a large horsepower, for example, to supply fresh vegetables. Fruit, livestock and goods of high efficiency, 6 x 2 and 6 x 4 HP gap will be more and more small, what do not understand can ask, code is not easy, landlord to praise.
Q:Are trailers the same as trailers?
The one that pulls the container is the trailer. Tractors are powered by power and can be used by another sport. A locomotive is a tractor
Q:When all the trains are turned back, it is necessary to avoid a larger angle between the tractor and the trailer. Why is it wrong?
The car and the trailer are 180 degrees in a straight line, and if you bend the car a little bit, the angle will be greater than 180 degrees, of course, the maximum is not even 360 degrees. Unless they are separated and together, it is 360 degrees, avoiding larger angles!
Q:What is a tractor?
The difference between a truck and a truck:"Three short short beam, short wheelbase, rear suspension (rear axle extending after the short part);There are more gear stalls, some from low to high speed with 12 stalls;The tank is bigger and usually double tank;Compressed air storage tank has more capacity;
