The vehicle body assembly is assembled from a number of parts, components, assemblies or accessories, including engines, transmissions, steering gears, etc.

The vehicle body assembly is an automobile component that is assembled from a number of parts, components, assemblies or accessories and has independent functions, such as engine, transmission, steering gear, front axle, rear axle, body , frame and cab, etc.

In automobile manufacturing, assembly or maintenance work, each assembly is usually organized as an independent structural unit to organize production. Some major automobile assemblies must undergo performance testing in accordance with certain technical specifications before being installed on the vehicle.

In automobile repair, the assembly exchange method is sometimes adopted, that is, an assembly is removed from the car and replaced with a new one or a repaired and inspected assembly, thereby shortening the length of the car. Repair downtime is reduced, and it is conducive to the organization of repair operations and the improvement of work quality.

To put it simply: an assembly is a general term for a system of parts and components that form a series of products into a whole to achieve a specific function. Assembly, which means a collection.

For example: the transmission shaft assembly on a car, that is, a collection of various transmission shaft related parts, which can realize power transmission.

The engine assembly refers to the overall synthesis, including the internal combustion engine, starter, oil pump, etc. It is a machine that can work completely, so it is called an assembly.

Notes on the car body assembly:

The bus body is an all-metal welded structure, which is welded from four parts: the chassis, side walls, roof and end wall. A metal floor is welded to the outside of the steel frame. The side wall panels, roof panels and end wall panels form a closed shell with a rounded upper part and a rectangular lower part, commonly known as a thin-walled cylindrical structure car body.

In addition to strengthening the interior of the shell with longitudinal rods, transverse beams and columns, wall panels are also used to replace some of the rods to enhance the strength and stiffness of the structure and form a reasonable overall load-bearing structure. .
