I want you to know the chassis knowledge you need to know about a special vehicle (1) heavy haul rollover Trailer.

When it comes to special vehicles, we have to think of their special equipment. That is why special vehicles have become the indispensable major equipment for transportation and special operations in the national economy. The chassis, as the basic part of the special vehicle, is also the relative core part, which plays a vital role in the special performance and function of the special vehicle.

Chassis structure

The basic composition of the chassis is relatively simple, generally including the transmission system, driving system, steering system and braking system, but each part of the function and mutual cooperation is more complex, the follow-up will be gradually unveiled for everyone.

Classification of chassis

The classification of chassis is mainly based on the classification of special vehicles, and according to the provisions of GB/T17350-2009, the classification of special vehicles can be divided into the following categories:

Special cars also include skeleton cars and heavy load rollover trailers.

Conventional van, tank car, special dump truck and so on usually adopt the second kind of automobile chassis refitting design; passenger car, passenger and freight car, van truck and so on usually adopt the third kind of automobile chassis refitting design.

The specific classification of chassis is as follows: one, two, three and four chassis.

A chassis is the vehicle in general sense, which includes all the vehicle systems.

Class II chassis lacks carriage system assembly, but has driving area, front instrument, operating system and so on, can run normally. Most of the special vehicles need special tools, so the second type chassis provides a natural basis for special vehicles, becoming the most used type of chassis.

Class III chassis has no body, but has engines, transmission, front and rear axles, steering gear, suspension, wheels, braking systems, etc., can not be used.

The four kind of chassis without molding part is basically the parts of the entire chassis system of the vehicle.

In fact, one to four types of chassis can also be called a class I, class II, class III and four types of automobiles, in the field of special vehicles, the concept of chassis is used more.

Chassis naming

Chassis naming rules are similar to the domestic automobile model rules, which are divided into the first part, the middle part and the tail part, and the rules of each part are basically the same. Taking Chusheng brand CSC5256GJBS concrete mixer as an example, the chassis model of "SX5256GJBDR404" is used. Through comparison, it can be seen that, except for the first enterprise name code and the tail enterprise self-designated code, the code of the special vehicle information of "5256GJB" is the same. If necessary, you can refer to http://news.chinacar.com.cn/newsview113644.html.

The code for chassis related enterprises is as follows:

Chassis enterprise code

Chassis drive mode

Chassis drive form largely determines the vehicle's passing capacity, the more drive, the stronger the vehicle's passing capacity, but the more complex the structure, complete quality and manufacturing costs also increase accordingly.

At present, there are 4 * 2, 4 * 4, 6 * 2, 6 * 4, 6 * 6, 8 * 4, 8 * 8, 10 * 4 automotive driving forms, the first digit represents the total number of automotive wheels, the last digit represents the number of driving wheels. According to the use and quality requirements of special purpose vehicles, we can choose the appropriate drive form, the general 4 * 2 drive form, simple structure, low manufacturing cost, more widely used.

As a basic part of the car, the structure of the chassis is relatively complex, using more knowledge and principles, and troublesome, this time we have a basic understanding of the classification, naming and driving form of the chassis, I believe that with the deepening of understanding, we will have a new understanding of the chassis.
