Description

A well-shaped combined tray embedded vehicle frame

technical field

The utility model relates to a well-shaped combined tray inlaid vehicle frame.

Background technique

At present, the transport semi-trailers on the market have changed with the change of the transport owner's business philosophy. The vehicles are required to be light in weight, resistant to bending, strong in carrying capacity, beautiful in structure and easy to maintain. When marble, roll paper and other materials are used, the position of the standing column between the second and third railings from the front of the frame appears to collapse, and the rear of the frame has a slump phenomenon. After the vehicle is loaded, the wave shape is obvious, which affects the aesthetics. As a result, the actual center of mass position of the vehicle and the axle load of the vehicle are different after the same loading of the vehicle, and even tire grinding and gnawing occur during the operation of the vehicle, and even local structural parts crack, which greatly reduces the carrying capacity and greatly reduces the load capacity of the vehicle. Safety, life cycle, and operating costs all pose varying degrees of concern. And these are contrary to the concept of safety, economy, durability, ease of use, and matching vehicle demand advocated by the society.

Utility model content

The purpose of this utility model is to overcome the above deficiencies, and develops a well-shaped combined tray embedded vehicle frame of the utility model. The technical problem to be solved is: to install a built-in well-shaped welding tray through the variable section section of the gooseneck of the frame To enhance its bending resistance and load-bearing capacity, solve the problem of waist collapse and collapse of the neck and tail due to the installation of materials, and at the same time use the anti-deformation of the girder to compensate for the load-bearing deflection problem of the middle part of the vehicle, so that the frame has a good performance after loading goods. Straightness or upper deflection, in order to achieve the above object, the technical solution of the utility model is:

A well-shaped combined tray-inserted vehicle frame, including girders, is characterized in that: middle beams are arranged between the girders, side beams are arranged outside the girders, side beams are arranged between the girders and the side girders, and the front and rear sides of the girders are There are front end beams and rear end beams, and well-shaped trays are installed inside the necks of the two girders. The well-shaped trays are composed of trough-shaped longitudinal beams and middle beams. .

The top surface of the groove-shaped longitudinal beam of the well-shaped tray is on the same plane as the top surface of the girder.

The middle part of the girder is provided with a number of flanging round holes, and the tail is in an arc-shaped upturned structure. The girder includes a web, the upper side of which is the upper wing plate, and the lower side is the lower wing plate. Strengthen the slanted column.

The middle beam and the side beam are disconnected structures, and the side beam and the middle beam are provided with lightening holes.

The lower part of the rear end of the channel-shaped stringer is provided with reinforced connecting braces, and the slots of the channel-shaped stringer face each other and keep a distance.

Pre-join the two whole longitudinal beams of the cold-formed trough type and about five whole beams into a multi-combined well-shaped pallet frame assembly for use, and combine several punched beams with punched and flanged girders, side beams, and the aforementioned wells The glyph pallet frame assembly is spliced and welded into a vehicle frame with the help of tooling tires. A reinforced connection brace is set at the lower part of the two longitudinal beams of the pallet to weld the pallet and the rear cold-formed middle beam together, and the top of the two grooved longitudinal beams of the pallet The surface and the top surface of the longitudinal beam of the frame are on the same plane, and then accessories such as traction devices and suspension devices are welded on the frame to form the frame assembly of the semi-trailer. The beneficial effect of the utility model is that the strength and bending deflection of the weak link of the neck of the frame are greatly increased by setting the built-in well-shaped anti-bending and torsion-resistant tray on the neck of the frame, which improves the anti-bending performance of the frame when loading special goods. The deformation characteristics make the load distribution of each axle within the design range, enhance the aesthetics of the vehicle after loading goods, prolong the service life cycle of the vehicle, and reduce the user's maintenance and operation costs. Decomposing and moving forward obliquely reduces the collapse problem caused by the bending of the rear of the beam, making the vehicle more usable. The structural design can effectively reduce the section height of the girder neck under the condition of ensuring the front rigidity and bending resistance characteristics, that is, the height of the vehicle's bearing surface can be minimized under the condition of the same traction installation joint surface height, and the vehicle is strengthened. driving stability and safety. Compared with the neck structure, it adopts side plate reinforcement and three I-shaped longitudinal beams plus disconnected beam structure. Lighter and stronger.
