The auxiliary beam is a beam set above and close to the main beam, so as to evenly distribute the load on the main beam.
1. There are two channel steels under the carriage of the big truck, which are the girders from front to back.
2. Girder is the main load-bearing component of freight car, which bears almost all the weight of goods. The quality of the girder affects the service life and driving safety of the whole vehicle.
3. Girder, also called frame, is the matrix of automobile. Generally, it consists of two longitudinal beams and several cross beams, which are supported on the wheels through suspension devices _ front axle _ rear axle.
4. The car beam has enough strength and rigidity to bear the load of the car and the impact of the wheels.

Advantages of cars with crossbeams
1. The flexible rubber pad not only plays the role of cushioning and shock absorption for tires and suspension systems, but also plays the role of auxiliary cushioning, properly absorbs the torsional deformation of the frame and reduces noise, which not only prolongs the service life of the car body but also improves the ride comfort, and is widely used in limousines and some intermediate cars.
2. The chassis and the car body can be assembled separately and then assembled together, which can simplify the assembly process and facilitate the organization of specialization and cooperation.
3. There is a frame as the foundation of the whole vehicle, which is convenient for the installation of various assemblies and parts on the automobile, and it is also convenient for changing the vehicle type and refitting it into other vehicles.
5. The frame has a certain protective effect on the car body.
