In China, if it is customary to install sedans or automatic transmissions on cars, it is rare to be able to install this equipment on large trucks. Sinotruk and WABCO have collaborated for more than two years in the development of SMARTSHIFT, a smart shift manual transmission, and matched with the new product HOWO A7, opening a gorgeous chapter for the domestic heavy truck industry. Heavy truck HOWO A7 tractor Classic appearance international trend On the test track, eight Chinese heavy-duty trucks equipped with AMT transmissions lined up in a row, and their posture was spectacular. At this point, HOWO A7, who ranked first, caught my eye. When I first arrived, although the cold in the north was not very accustomed to me as a southerner, the mighty posture of the A7 made me enthusiastic. I was eager to urge me to make a comprehensive analysis of it. As the saying goes: To evaluate a thing, the first impression is most important. HOWO A7 has that feeling of love at first sight. A7 poses mighty A friend who is familiar with the car may not be unfamiliar with the reference to "Giorgio Rodriguez". It is a famous Italian design company and has designed cars for dream cars such as Maserati and Bugatti. With its original design concept, "Georgia Romano" provides capital for each car to show its own personality. Sinotruk cooperated with Georgian Luo Design Company to design a classic shape with an international trend. In particular, the newly designed combined headlight assembly integrates the light and fog lights. The staggered layout makes the novelty and aesthetic appearance, and the visual effect is simple and neat. In addition, a pair of combination lights is attached to the top of the windshield to provide good visibility for night driving. The bright side of the car comes from an aluminum alloy tank with a combination pedal, which is designed to make it easier for maintenance personnel to board the rear of the car for maintenance work. Newly designed combined headlamp assembly The installation position of the engine assembly of the HOWO A7 is improved by about 10 cm from the original HOWO series installation position, which improves the vehicle's passability. The interior of the cab has been modified from the commonly used imitation mahogany dashboard with warm-coloured trims. Between luxury and warmth, for commercial vehicles, I believe most people will choose to be warm. A7 takes full account of the driver's rest environment. The space inside the cab can not only accommodate a 180cm adult walking upright, but also the lower berth can be split into two seats and a small dining table. This kind of cab is rarely found in domestic heavy trucks. . A7 cab Newly designed sleeper and lounge Smart shift speed agility HOWO A7 uses a lot of humanized design concepts. Usually the driver is troubled by the small distance between the steering wheel and the seat when entering the driver's cab, and A7 solves this puzzle. After the driver stops, the driver can enter and exit the cab simply by pressing the pedal on the lower left side and adjusting the steering wheel to an orientation perpendicular to the ground. SMARTSHIFT-AMT also provides economy, power and climbing modes Can finally try "smart shift". SMARTSHIFT is an automatic mechanical transmission (AMT), which is based on mechanical transmissions and dry clutches, through the electronic control unit to control the selection, shifting and clutch operation. AMT is different from the structure of an AT that is usually used in cars. The latter is a mode in which the hydraulic oil is driven by the turbine and the hydraulic oil drives the mechanical device. The efficiency loss of the hydraulic oil drive is often large, so the fuel consumption also increases. It should be said that AMT's manipulation is similar to that of AT, and the structural principle is similar to that of MT, which weighs the respective characteristics of the two. In addition, this transmission has 4 built-in reverse gears, which is very easy to operate and can meet the traffic requirements under various operating conditions. Adjust the seat back to the most comfortable position, press and hold the "F (function)" key on the transmission and push it forward. The accelerator pedal is then depressed, and the A7 takes a big step forward in the sound of a high-pitched engine. . Because it is empty driving, the driver can force upshifts through manual intervention. In any case, this transmission is not its name, smart understanding of the driver's driving intention, timely upshifts, effectively reducing the driver's physical power consumption caused by the shift step clutch, so that they can fully observe the road conditions. Heavy truck A7 Only after a while, the A7 would speed up to about 80km/h unconsciously, at this time the engine speed was maintained at 1500r/min, close to the maximum torque speed. The windshield in front of the cab and the large area of ​​electrically adjustable rear-view mirrors on both sides provide excellent visibility. As the test drive site was arranged on the airstrip, the nearly-quick-drive A7 pulled a strong body like the plane took off! However, the high-speed running A7 did not bring much noise, thanks to the good noise reduction performance of the D12 engine and other assemblies. This engine adopts a new generation of electronically controlled common rail system of Denso Co., Ltd., and the spray atomization degree is more precise. Braking sensitive and safe As an A7 positioned in high-end heavy trucks, security performance cannot be ignored. A7 adopts "front and rear drum" configuration with ABS to optimize vehicle stability. Disc brakes are also the standard configuration of the world's high-end heavy trucks. Compared with drum brakes, they have high-speed, heavy-duty, and high-speed brake efficiency. . When the speed is increased to 80km/h, at the end of the test runway, I step on the brake pedal without delay. The body does not significantly lean forward under a strong inertial force, nor does it produce brakes and brakes. The phenomenon of dynamic deviation, but in a slow, gentle gesture to slow down. In addition, the body strength of the A7 is at the leading position in China, and a large number of body uses a non-sharp angle design and flame retardant materials. The frontal collision cabin can instantly move back 20cm, and passive safety is also quite outstanding. It is both a challenge and an opportunity 2008 was an extraordinary year, and this year was a year of ups and downs for commercial vehicles. However, Sinotruk resisted the pressure in the contrarian situation and made new achievements. It has made no small achievements. The work in 2009 is both a challenge and an opportunity for China National Heavy Duty Truck. At present, SINOTRUK has established 104 regional branches, 150 4S stores, 1102 dealership modification units, and 1,045 maintenance service stations. These historical figures fully prove that CNHTC has established a nationwide marketing network system. I believe that as long as we have confidence and capital, China National Heavy Duty Truck will certainly be able to seize the opportunity. The launch of HOWO A7 has met the needs of high-end users at home and abroad. Developing countries that are less affected by the financial crisis are the key markets for heavy-duty trucks' exports. If the domestic users are looking for more convenient, safer, more fuel-efficient and cost-effective heavy trucks, the A7 is also a good choice.

I vaguely remember that when I was learning a car a few years ago, I was struggling to step on the clutch and hold the gear. I accidentally extinguished the car, and I married the master's jealousy. Today's changes in the times and people's demanding driving efficiencies have made carmakers even more human-oriented, and automatic transmissions are also increasingly on the stage.

Tungsten carbide grits are often used as abrasives in cutting tools, grinding wheels, and sandpaper. They can also be used as an additive in metal alloys to improve their hardness and wear resistance. Additionally, tungsten carbide grits are used in the mining and drilling industry for rock drilling and excavation.
These grits are available in different sizes and shapes, such as spherical or irregular particles, depending on the specific application. They are typically produced through a process called sintering, where Tungsten Carbide Powder is heated and compressed to form a solid material.
Overall, tungsten carbide grits are highly valued for their hardness, durability, and resistance to wear, making them essential in various industries where high-performance materials are required.
