On trucks, we can often see some parameters such as "4x2, 6x2...", or hear people talk about "the first four after eight", although some people may know that these parameters represent the driving form of the vehicle. However, it is still unclear how to explain it. Therefore, it is necessary for everyone to popularize what is the 6x4 driver, what is the term 4x2 driver, and after understanding the advantages and disadvantages of different drive forms, it can also help everyone in the purchase of trucks have a more sensible choice.
What does "4x2, 6x2..." mean?
4x2, 6x2, 6x4, and 8x4 These combinations of “multiply by several†are not just random calls. The preceding numbers and the following numbers have specific meanings. The number before the "x" sign indicates the number of tires (groups), and the number after the "x" sign indicates the number of drive wheels (groups). For example, the 4x2 model means that the car has 4 sets of wheels, of which 2 sets of wheels have a driving force; 6x4 models indicate that the car has 6 sets of wheels and 4 sets of wheels have a driving force. Do not confuse the two numbers before and after, and come up with strange words such as 4x6 and 2x4.
It should be noted that truck driveshafts are generally designed with double tires installed. That is, each tire on the side of the driveshaft is fitted with two tires. How should this be calculated? As long as two tires are put together, they will count one tire group. For example, in the 6x4 model, there are 10 tires in total. There are 2 steering shafts and 8 drive shafts. Each of the 2 wheels is mounted together. We can only count 4 groups of tires. We cannot simply use the number of tires as the driving format. Otherwise, the 6x4 model will become 6x8.
Strong off-road vehicles are generally all-wheel-drive, and life should also be able to see some cars marked with "4x4" or something. Trucks also have all-wheel-drive 6x6, 8x8 and other drive forms applied to some special vehicles. In most cases, the greater the number of drive wheels, the stronger the driving force of the vehicle and the better adaptability to the road conditions. This time can easily sum up the advantages and disadvantages of the tractor 4x2 and 6x4 drive.
Simple understanding of the advantages and disadvantages of the drive format
One, 4x2 drive form
Advantages: Because there are only 2 axles, the axle distance is short, the vehicle is flexible, and the weight is light. Small number of tires, better fuel economy, more fuel economy, and low cost of purchase.
Disadvantages: The number of driving wheels is small and the driving force is weak. In a slightly bad road condition, it may be difficult to get out of difficulty. With the help of various advanced electronic assistance systems, it can play a certain role in improving.
Second, 6x4 drive form
Advantages: There are 4 driving wheels, and the driving force and road adaptability are relatively strong, especially the wet and slippery road vehicles such as winter rain and snow have better stability and are not easy to slip out of control.
Disadvantages: The 6x4 drive is a bit wasteful when the road is in good condition, and the tire wear and fuel consumption are relatively large. The weight and structure of the drive shaft are also heavier and more complex than the load-bearing shaft, and the vehicle has a large weight and high purchase cost.
The 5XZC-L laboratory seed cleaner & grader is precision equipment for particulate material cleaning and grading. It is suitable for separation of all seed types, as grain, grass seeds, flower seeds, vegetable seeds, herb seeds and so on.
Working principle:
Lab seed cleaner is mainly used for all kinds of seed processing characteristics test and research. It is also widely used for quantity high-value seeds cleaning and size classification. The seed cleaner is air screen structure. It has former and rear dust separating air pipes, so you can clean the dust, light impurities and blighted seeds from good ones. Vibrating sieve trunk is installed 3 sieve layers in the upper, middle and lower part. First sieve layer is used to separate large impurity & large seeds. Second sieve layer is used to separate small impurity & small seed. The rest seeds are qualified seeds and they go to main discharge outlet. By adjusting the frequency converter button, you can control the sieve trunk vibration and control material running speed on sieve screen surface. There are also several air volume adjusting handles to help you get the suitable air suction. So you can well manage the seed cleaning effect by adjust trunk vibration frequency and air volume. At bottom of the sieve trunk, there is an air filter. Dusty air produced after winnowing will be discharged after filtering. This is environmental protection design.
Feature:
Lab seed cleaner & grader is two air screens structure. The front and rear part both has one air cleaning system. In air cleaning procedure, it removes dust, light impurities and unfilled seeds. Vibration sieve trunk is equipped with three sieve layers which used to separate large impurity, and small impurity. After whole cleaning processing, qualified seeds are separated from impurity.
