How to distinguish the number of axles of the truck, how to distinguish the tonnage of the rear axle

Generally speaking, a truck with several rows of tires under the trunk is a multi-axle vehicle, a row of tires is a single-axle vehicle, two rows are a double-axle vehicle, and so on. A few bridges are a few axles, that is, there are several rows of wheels. The steering wheel set that includes the front axle and the rear drive load-bearing wheel set at the rear are the rear axle.

Common appellations often refer only to the number of rear axles, such as single axles for trucks, double axles at the rear, triple axles at the rear, etc. The axle, also known as the axle, is connected to the frame (or load-bearing body) by suspension, and the wheels are installed at both ends, and its function is to transmit the force and torque in all directions between the frame (or load-bearing body) and the wheels. According to the role of the wheels on the axle, the axle is divided into:

Drive axle, steering axle, steering drive axle, support axle. Among them, the steering axle and the support bridge belong to the driven bridge"Single-axle and double-axle vehicles"of"Bridges"Refers to the drive axle, the double-axle car is a car with 2 drive axles, and the single-axle car is a car with one drive axle. Axles can also be divided into two types: integral and disconnected according to different suspension structures.

Extended information: According to the Measures of the People's Republic of China for the Registration of Motor Vehicles, trucks can be divided into four categories: heavy, medium, light and miniature. Among them, heavy and medium-sized trucks are issued with large truck number plates, that is, large vehicles (commonly known as yellow plates); Light and mini trucks are issued with number plates for minivans, i.e. small vehicles (commonly known as blue plates).

According to the provisions of the driving license, the single-axle car of the meter can be loaded with 5 tons of goods, the double-axle car of the meter can be loaded with 15 tons, and the meter trailer of the three axles can be loaded with about 20 tons.

This is very simple, standing on the side of the car, you can see that a few wheels are a few bridges, two-wheeled ones are counted as single wheels, at least two bridges, generally, up to seven bridges, Steyr.

A lot of series,

Look at how many wheels are the easiest to identify.

According to the number of axles in the truck, a single-axle car is a vehicle with a single drive axle and a single directional wheel.

Double-axle cars are dual-axle, single-direction wheels, or two-way wheels, single-drive axles.

The three-axle car is a single-machine or single-drive single-wheel tow + rear double-axle semi-trailer with double drive axle and two-way wheels.

The four-axle car is a tractor with a single drive and a single directional wheel + a semi-trailer with a rear three-axle or a double-drive axle + two-way wheel + a single drive with a floating axle + a tractor with a single drive and a single wheel at the rear three axles.

The six-axle car is a double-drive single-direction wheel tow + rear three-axle semi-trailer or single-drive two-way wheel tow + rear three-axle semi-trailer.

According to the Terminology of Motor Vehicle Construction, vans are classified as automobiles and are divided into eight categories.

1. Ordinary trucks: trucks with steeplechase structures in the cargo parts, excluding trucks with automatic dumping devices.

2. Van truck: the structure of the cargo part is a cargo truck with a closed envelope and independent of the cab.

3. Closed truck: the structure of the cargo part is a closed envelope and is integrated with the cab, and the body structure is a van truck.

4. Tank truck: the structure of the cargo part is a truck with a closed tank.

5. Flatbed truck: the floor of the cargo part is a flatbed structure and a truck without a steeplechase plate.

6. Container van: the cargo part is a frame structure and has no floor, and it is a cargo truck specially designed to transport container compartments.

7. Dump truck: a truck with an automatic dumping device at the cargo part.

8. Special structure truck: the cargo part is a special structure, which is a cargo truck specializing in transporting specific items. For example, a double-layer structure truck transporting a car, and a multi-layer structure truck transporting live livestock.

The bridge refers to the shaft used as the drive, the single axle refers to one drive axle, the double axle refers to two, and the third bridge also refers to the double bridge in some places, because he counts one front axle, adding up to three, and the four axle refers to the front two rows of guide wheels and the rear two drive axles, a total of four axles

The number of bridges is directly proportional to the length and load capacity of the truck.

The more bridges, the greater the length and load capacity.

There are many bridges and many cargo. It's also very cool to drive in the bridge.

There are five parts to the content of the vehicle code: 1. The enterprise name code; 2. Vehicle class code; 3. Main parameter code; 4. Product serial number; 5. The company sets its own code.

1. The enterprise name code is indicated by 2-digit Chinese pinyin. For example, CA stands for FAW, EQ stands for Second Automobile, BJ stands for Beijing, and NJ stands for Nanjing.

2. The vehicle class code is represented by 1-digit Arabic numerals. 1 is used to represent trucks; 2 indicates off-road vehicles; 3 indicates dumping trucks; 4 indicates a tractor; 5 indicates a special vehicle; 6 indicates passenger cars (large, medium and small); 7 means car; 8 means trailer; 9 means semi-trailer and extended cargo trailer.

3. The main parameter code is represented by 2-digit Arabic numerals. In trucks, these two digits represent the total mass of the vehicle (the sum of the vehicle's weight and carrying capacity); In cars, these two digits indicate the car's displacement in liters; These two digits in passenger cars indicate the length of the body (unit:

m）。4. The serial number of the product is represented by 1 Arabic numeral. Alterations and modifications of the model are indicated by .

5. The company sets its own code.

The first automobile factory enterprise self-determined code: A - with air conditioning B - dump C - super luxury or tractor chassis diesel car D - bus chassis E - high steeplechase K - diesel car K2 = Dalian diesel engine, K1 = German Deutz engine, K4 = Wuxi diesel engine P - flat head car P = two wiper blades flat head two wiper blades flat head cab FK cab. P1 = three wiper blades flat-head cab, nearly 200mm wider than P FP cab.

P2 = widened type three wiper blade flat-head cab, nearly 312mm FM cab wider than P1. If the custom part of the enterprise has P or P1 and H at the same time, the cab is widened by one level on the basis of P or P1 R - with sleeper S - fuel truck chassis T - double axle drive L - long wheelbase Y - right direction Z - export car H - wide-body cab Example: CA 1 09 0 K2L2 1 2 3 4 5 1 - enterprise name code 2 - vehicle category code 3 - main parameter code 4 - product serial number 5 - enterprise self-determined code.

There are two main technical parameters for the rear axle, the load level and the speed ratio.

1. The bearing level is the maximum bearing mass of the rear axle design. In tons, such as six tons, ten tons, eleven tons, etc., domestic roads exceeding thirteen tons are prohibited.

2. Speed ratio: the gear transmission ratio of the main drive axle in the automobile drive axle, simply put, how many times the transmission shaft rotates and the tires turn once. For example, the speed ratio of a car is, that is, the transmission shaft turns and the tires turn once;

Generally, the rear axle of the truck is marked, the higher the speed ratio of the engine, the larger the speed ratio is suitable for pulling heavy goods or climbing the mountain road, the vehicle is strong but the fuel consumption is high, the speed ratio is small for light trucks to run, and the fuel consumption is low but not suitable for running mountain roads.

Fundamentals of work

Power is transmitted from the engine to the gearbox, through which it is transferred to the large chainring on the rear axle. The differential is a whole, inside is: there is a small chainring up and down, there is a cross post in the middle with two asteroid gears on it, which plays the role of turning speed regulation The differential is placed vertically, there are two small round holes on both sides, and there are sliders on it, and the half column we often say is inserted in this, and the cross column does not move when walking in a straight line, and the cross column moves to adjust the speed of the tires on both sides when turning, so as to improve the maneuverability of the car when turning!

Wait a minute. Look at the model number on the plate. The two digits in the middle of the truck nameplate are the total mass of the car, which is the total weight of the self-weight and the allowable load, and 09 means that the total mass is 9 tons.

The fourth digit indicates the series of different models of the same tonnage of the manufacturer). The total mass is the total tonnage of the front and rear axles, and the front axle is generally about half of the weight of the rear axle.

Questions. The 325h rear axle is a multi-ton bridge.

According to the load, it is divided into nine tons, ten tons, thirteen tons and sixteen tons; According to the drive form, it is divided into single reduction axle and wheel side reduction axle. Heavy truck axles will be marked with a sign.

Questions. <>

What kind of bridge is this.

Wrong. There is no uniform format for the manufacturer's numbering of the rear axle, mainly depending on the two parameters it provides.

The load level is the maximum load weight of the rear axle design, expressed in tons, such as: 6 tons, 10 tons, 11 tons, etc. Domestic roads over 13 tons are prohibited.

For example, it is the model of the truck (the first digit "1" represents the truck), the middle two digits are the total mass of the car, that is, the total weight of the self-weight and the allowable load, and "09" means that the total mass is 9 tons. The fourth digit indicates the series of different models of the same tonnage of the manufacturer). The total mass is the total tonnage of the front and rear axles, and the front axle is generally about half of the weight of the rear axle.

As follows:

The micro-cargo model is generally .

Light trucks and dump engineering trucks are available.

The latter two types of Hande and Steyr belong to the special use of heavy trucks, and there are also lengthened, shortened, and standard types in these models.

Care attention. The maintenance of new cars should be done sufficiently, most car owners will go to the special service station to do maintenance in accordance with the manufacturer's regulations, because most car manufacturers have implemented the first warranty free oil change discount for new cars. For example, Shanghai GM will provide 4 free oil and oil filter replacement services during the warranty period.

However, there are also a small number of car owners who neither consult the staff nor read the "Maintenance Manual", so there are also examples of missing the first warranty. Because it is a new car, the owner misses the first insurance, and it is only the oil that becomes black and dirty, which will not cause any serious consequences.
