Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle beams, and in particular relates to a vehicle beam structure. Background Art

[0002] The automobile beam is a vital component of its parts. It is the base of the car and is usually composed of longitudinal beams and cross beams. The beam is usually located at the front axle and rear axle and supported on the wheels. On a large truck, it usually runs from one end of the car to the other. These are the beam structures, also known as the frame.

[0003] The beam is very important in automobiles, especially in large trucks, as it supports almost all the weight of the cargo on board. The quality of the beam directly affects the cargo capacity, service life, and safety of large trucks. The beam of a large truck is very easy to be damaged when it is under great pressure, especially at the position where other functional components are integrated. After a large amount of damage accumulates for a long time, it will cause the problem of breakage. Utility Model Content

[0004] In order to solve the technical problem in the background technology that the vehicle beam is easily damaged by huge pressure, the purpose of the utility model is to provide a vehicle beam structure that can solve the above problem.

[0005] The technical solution for achieving the purpose of the utility model is: a vehicle beam structure, including a longitudinal beam, a cross beam and a reinforcing beam, a plurality of cross beams are fixed on two longitudinal beams, and the reinforcing beam is also fixed on one end of the longitudinal beam, and the reinforcing beam is located on the end of the beam close to the front of the vehicle.

[0006] The reinforcing beam is located at the head of the beam, where it needs to be connected to the front of the vehicle. There are many functional components, and the vehicle will also set up a mechanism to support the tilting of the car body, so the beam here is at a greater risk of damage. The reinforcing beam is fixed between the two longitudinal beams here to enhance the bearing capacity and resistance to shear and deformation. After strengthening, it can not only withstand greater prestress, but also other functional components can be installed with confidence, and the connection performance with the front of the vehicle is also strengthened, the safety factor is improved, and the service life is longer.

[0007] Further, the reinforcing beam includes a reinforcing longitudinal beam and a reinforcing cross beam, the two reinforcing longitudinal beams are respectively fixed on the two longitudinal beams, and the reinforcing cross beam is connected between the reinforcing longitudinal beams. Similar to the connection between the longitudinal beam and the cross beam, the reinforcing longitudinal beam is fixed on the longitudinal beam, and the reinforcing cross beam is symmetrically connected to the end of the reinforcing longitudinal beam, so as to improve the reinforcing performance and strength of the reinforcing beam and play a reinforcing role of the reinforcing beam.

[0008] Furthermore, the reinforcing beam is welded to the longitudinal beam, which can prevent problems such as loosening in the later stage and affect the function of the reinforcing beam compared with bolt connection.

[0009] Furthermore, the end of the cross beam extends to the outside of the longitudinal beam, and a hinge seat is provided on the end of the cross beam for hinged connection with the vehicle box body. It can play the role of hinged connection when fixing the box body, and secondly, it is convenient to separate from the car body when the car body needs to be overturned, and both disassembly and installation are relatively convenient.

[0010] Furthermore, an oblique support plate is installed between the end of the cross beam and the longitudinal beam, and the oblique support plate is connected under the cross beam to improve the supporting force of the cross beam. Even if the end of the cross beam extends to the outside of the longitudinal beam, a larger pressure can be supported due to the existence of the oblique support plate.

[0011] Furthermore, a hydraulic telescopic rod for driving the carriage to rise is arranged on the reinforcing beam, and the reinforcing beam is located at one end of the longitudinal beam. The hydraulic telescopic rod is arranged here to lift the carriage toward the rear of the vehicle, so as to facilitate the rapid unloading of the goods in the carriage. Due to the existence of the reinforcing beam, the pressure-bearing performance here is stronger, and functional components such as the hydraulic telescopic rod can be installed with confidence.

[0012] Furthermore, it also includes a rotating seat and a connecting frame, wherein the rotating seat is installed between the end of the longitudinal beam and the connecting frame, and the connecting frame is installed on the front axle of the vehicle and connected to the front of the vehicle. The rotating seat is rotatable, that is, the connecting frame and the longitudinal beam are rotatable. When the front of the large truck and the car body rotate, due to the connection of the rotating seat, the front of the truck and the car body can be rotated at a more flexible angle, and can also be flexibly rotated in a smaller space.

[0013] Furthermore, the rotating seat is located at the position of the reinforcing beam and is welded to the longitudinal beam and the reinforcing beam respectively. Specifically, the rotating seat is welded and installed below the reinforcing beam, and can withstand a large driving force when the front of the vehicle pulls the carriage. The existence of the reinforcing beam ensures the strength and the beam will not be damaged.

[0015] (1) A reinforcing beam is welded at the end of the vehicle beam to improve the bearing capacity of the beam, and other functional components can be installed here;

[0016] (2) The reinforcement beam is fixed by welding and includes a reinforcement longitudinal beam and a reinforcement transverse beam to ensure the reinforcement effect of the reinforcement beam;

[0017] (3) The ends of the cross beams extend outside the longitudinal beams and are provided with hinged seats to facilitate hinged connection with the vehicle;

[0018] (4) A hydraulic telescopic rod and a rotating seat are respectively arranged at the position of the reinforcing beam to realize the unloading of the truck and the rotation of the front and the carriage, thereby ensuring the supporting strength of the end of the beam and allowing more functional components to be installed with confidence.
