Description
Technical Field
The invention belongs to the technical field of frame assemblies, and particularly relates to an assembled type truck frame assembly.
Background
Most modern automobiles have a frame as a full vehicle skeleton. Most components and assemblies of the vehicle are secured by the frame, such as the engine, drive train, suspension, steering system, cab, cargo box and associated operating mechanisms. The frame plays a role in supporting and connecting various parts of the automobile and bears various loads from the inside and the outside of the automobile.
A truck (Wagon) is a commercial vehicle designed and equipped primarily for carrying cargo, whether or not it can tow a trailer.
Cargo vehicles, commonly referred to as trucks, also known as lorries, refer to vehicles primarily used for transporting cargo, and sometimes to vehicles that can tow other vehicles, and are a category of commercial vehicles. Generally, the vehicle can be divided into a heavy vehicle and a light vehicle according to the weight of the vehicle. Most trucks use a diesel engine as a power source, but some light trucks use gasoline, petroleum gas, or natural gas.
The frame is designed to meet the requirements of the overall arrangement of the motor vehicle. During complex driving of the automobile, interference between assemblies and components fixed on the automobile frame should not occur. When the automobile runs on a rugged road, the frame may generate torsional deformation and bending deformation in a longitudinal plane under the action of load; the entire frame may also twist into a diamond shape when one of the wheels encounters an obstacle. These deformations will change the relative position of the components mounted on the frame and thus affect its proper operation. Therefore, the frame should also have sufficient strength and appropriate rigidity. In order to improve the light weight level of the whole automobile, the mass of the frame is required to be as small as possible. In addition, the frame should be arranged close to the ground, so that the center of gravity of the automobile is lowered, and the driving stability of the automobile is improved. This is particularly important for trucks.
