[car home] I don’t know if everyone has seen it just now. Six mainstream hard-core off-road vehicles with different prices on the market competed in several projects, showing their off-road strength and different characteristics. Well, I’ve seen them competing in the same field. The graphic content focuses on the comprehensive performance of each bicycle in all events. If you happen to want to buy a hard-core off-road vehicle recently, I believe the following contents will help you choose to buy it. The protagonist of this article is (|). In addition, we have also produced a detailed analysis article of tank 300 four-wheel drive, and interested friends can click to watch it.
Tank 300 2.0T Conqueror is a mid-equipped model in the whole department. In the original factory state, the approach angle is 33, the departure angle is 34, the longitudinal passing angle is 23.1, the minimum ground clearance is 224mm and the maximum wading depth is 700mm, so the congenital conditions are good. The 2.0T engine has a maximum power of 227Ps and a maximum torque of 387N·m, matching the 8AT gearbox.
Tank 300 2.0T Conqueror adopts part-time 4wd structure, and also has two differential locks at the front and rear. The torque of low-speed four-wheel drive mode can be enlarged by 2.48 times, and it has its own tank turning and crawling mode. It is also one of the only two cars with front locks in this cross-evaluation, and it should be said that it is relatively strong in hardware.
K&C is called Kinematics and Compliancs in English, where K stands for geometric kinematics characteristics of suspension, and C stands for elastic kinematics characteristics of suspension. K&C characteristics jointly determine the posture and position of the wheel when it jumps, as well as the driving performance of the vehicle. K&C experiment is an important link to ensure the handling, stability and driving experience of the vehicle in the process of vehicle development.
Five kinds of sensors are used in this experiment, including front and rear seat cushion sensors, sound pressure sensors of front and rear seat cushions, and multiple unidirectional and three-directional acceleration sensors installed on the steering wheel and the guide rail under the seat respectively, in order to avoid the interference of the seat cushion and simply look at the chassis performance.
We will simulate three different bumpy road conditions, A, B and C, in which A road condition is equivalent to an asphalt road that has been in disrepair for a long time, B road condition can be regarded as a vehicle passing through cobblestone roads, and C road condition is basically a bad unpaved road that is often encountered during long-distance crossing.
Let’s draw a conclusion directly. After several rounds of tests and calculations, in the interior noise test, the performance of Tank 300 can be ranked second among the six models, second only to Beijing BJ40. In the ride comfort test to measure the human vibration evaluation index, from the data obtained by the sensors on the front and rear seats and the seat guide rail, several cars did not open the obvious gap, which was far below the safety threshold. From the vibration data measured at the steering wheel position, the performance of Tank 300 can rank fourth among the six cars.
In the tension test, we can see the tension values obtained by four wheels, two wheels or even a single wheel in different four-wheel drive modes through the data. In the actual off-road situation, if a wheel loses its grip, you can also know more clearly what mode can make it easier for you to get out of trouble.
When the full-wheel tension of tank 300 in 4H mode is 2362kg, the tire will break through the grip and slip, resulting in data decline. Using the 4L mode with greater torque will only make the tire break through the grip limit earlier, and the performance has not improved again. In the front axle tension test, the difference between 4H and 4L modes is very small, which is 1281kg and 1284kg respectively. The difference is that 4L mode is more likely to break through the tire grip limit. In the rear axle tension test, the tension in 4L mode is slightly higher than that in 4H, which is 1398kg and 1326kg respectively, which is slightly higher than that in the front axle as a whole.
In the cross-axle test, the power output will be limited when using the 4-hour mode, and the rotation speed will be limited to 1100rpm, and the tension will be 864kg； when the rotation speed limit is lifted after the rear lock. The effect of using 4L mode is obvious, and the tension value increases to 1052kg. However, if the rear differential lock is locked at this time, although the power output is more direct, the wheel will instantly break through the grip, so the measured data will be lower, which is 824kg. The mode that can get the maximum pulling force in the cross axle test is 4L+ front and rear locks, at which time the vehicle can get the pulling force of 1285kg.
In the single-wheel tension test, there is no doubt that the tension when the single rear wheel has adhesion is greater than that when the single front wheel has adhesion. Whether in 4H or 4L mode, the tension of the single front wheel is 250kg, while that of the single rear wheel is basically 400-500kg. After locking the differential lock, the situation has been greatly improved. In the mode of 4L+ front and rear lock, the pulling force of the single front wheel can reach 816kg, which can basically reach the same level as that of the single rear wheel 4H padlock, while the single rear wheel has the largest data of 895kg when it is 4L padlocked.
Field cross-country is the best way to test the comprehensive quality of a hard-core SUV. We still came to the Kaiser cross-country venue to see their performance.
The 80% ramp is just an appetizer for the tank 300. Under the condition that the tires have adhesion, it can be easily climbed to the top only by using the 4H standard mode, and the engine speed is only 2000rpm in the whole process. There was no accident in the performance of 66% side slope, and there was no sign of downward sliding of the vehicle during the whole process.
In the Big Butterfly Valley project, the standard mode is still 4H, and the vehicle can easily pass through with the throttle stabilized. During the whole process, the electronic limited slip intervention is quick after the wheel loses adhesion, and there is not too much invalid idling, and the vehicle is relatively stable when the center of gravity shifts. However, because the suspension setting of the tank 300 is soft, some "seesaw" effects are easy to appear when the vehicle reaches the top.
The height of each steamed bread bag crossing the shaft on the difficult level is 45cm, which not only examines the slip-limiting ability of vehicles, but also puts forward certain requirements for passing. In this link, the tank 300 directly uses the low-speed four-wheel drive+rock mode. At this time, the vehicle will close the ESC and lock the rear differential. In this case, the tank 300 has no difficulty in passing, and the basic idle crawling state can pass the test.
The most difficult project this time is the 80% uphill cross axle, which is a comprehensive test of the off-road ability of vehicles. Power, passability, four-wheel drive distribution ability and even vehicle weight will affect the passing effect of vehicles. The tank 300 still uses the 4L+ rock mode. In addition to hanging the rear lock, the driver manually locked the front differential this time. In the whole climbing process, the challenge can be completed only by stepping on the accelerator deeply when crossing the shaft. However, when climbing to the top, the side pedal of the vehicle will rub against the ground. On the whole, the performance of the tank 300 in this field cross-country can be said to be excellent.
It’s not unreasonable for Tank 300 to be the best-selling hard-core SUV in the market at the level of 200,000 yuan at present. In addition to its pleasing retro square box appearance, its four-wheel drive performance can stand the test. Excluding the influence of vehicle configuration on off-road performance, the approach angle and departure angle of the tank 300 ensure its passability, and the calibration of the electronic system is also very mature, which are its advantages. In addition, many mature modification cases and parts on the market provide great convenience for the owner’s later upgrade, which is also related to its huge user base, so it is basically still one of the most worthwhile off-road vehicles at this price.
