Description

Technical Field

[0001] The utility model relates to the technical field of tank truck frames, in particular to a tank truck frame beam structure. Background Art

[0002] In the field of special-purpose vehicle industry, the problem of high center of gravity height of tank vehicles has always existed. The GB7258 standard limits the roll stability angle of tank vehicles to within 23 degrees. In the field of transportation, there are indeed many tank vehicles that are prone to rollover due to the height of the center of gravity.

[0003] At present, when the roll stability angle still does not meet the standard after taking most measures, car companies generally reduce the diameter of the circular tank to solve the problem of the roll stability angle not meeting the standard due to the high center of gravity. However, due to the limitation of vehicle length, the length of the tank will also be limited, resulting in the problem of small tank volume. Utility Model Content

[0004] The purpose of the utility model is to provide a frame beam structure of a tank truck to overcome the above-mentioned defects in the prior art.

[0005] A frame beam structure of a tank truck includes a frame longitudinal beam, a frame cross beam and a suspension bracket. A plurality of frame cross beams are evenly distributed between two frame longitudinal beams. The suspension brackets are provided with a plurality of and are vertically arranged at the bottom of the frame longitudinal beams. A plurality of air spring fixing plates are also provided at the bottom of the frame longitudinal beams.

[0006] Preferably, the frame longitudinal beam is a "Z"-shaped structure.

[0008] Preferably, the folded edge is connected to the frame longitudinal beam by fixing bolts.

[0009] Preferably, a plurality of weight-reducing circular holes are provided in the transverse portion of the bent plate.

[0010] The utility model has the following advantages:

[0011] This patent realizes a novel structure of the tank truck frame beam through innovation, a Z-shaped frame longitudinal beam and a variable-section frame cross beam. Compared with the conventional structure, without increasing the cost or reducing the strength of the frame structure, the upper tank body can be arranged at a significantly lower height. This frame beam structure is particularly suitable for tank trucks with round tank bodies. It can effectively reduce the center of gravity height, increase the roll stability angle of the tank truck, and improve the driving stability and safety of the tank truck. It has a good market application prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The specific implementation methods of the utility model are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model.

[0017] like Figure 1-3 As shown, the utility model provides a frame beam structure of a tank truck, including a frame longitudinal beam 1, a frame cross beam 2 and a suspension bracket 3. The frame longitudinal beam 1 is a "Z"-shaped structure, and the upper wing surface of the frame longitudinal beam 1 is located outside the longitudinal plane of the frame, so that the height of the tank body can be reduced, and holes can be drilled on the upper wing surface or the vertical web of the frame longitudinal beam 1 to cooperate with the supporting components of the upper tank body.

[0018] A plurality of frame cross beams 2 are evenly distributed between the two frame longitudinal beams 1. A plurality of suspension brackets 3 are vertically arranged at the bottom of the frame longitudinal beams 1. A plurality of air spring fixing plates 4 are also arranged at the bottom of the frame longitudinal beams 1. The welded suspension brackets 3 and air spring fixing plates 4 can be used to connect the frame with the lower suspension.

[0019] It should be noted that the frame crossbeam 2 includes a bent plate 21 and an arc plate 22, and an arc plate 22 is welded between the tops of the two bent plates 21, thereby increasing the torsional resistance of the frame crossbeam;

[0020] The transverse part of the bending plate 21 adopts an arc-shaped variable cross-section structure to facilitate the sinking arrangement of the tank body. Both sides of the bending plate 21 are provided with folding edges 23, and the folding edges 23 are connected to the frame longitudinal beam 1 through fixing bolts 24;

[0021] A plurality of weight-reducing circular holes 25 are provided in the transverse portion of the bending plate 21 to reduce the weight of the bending plate 21 .

[0022] In summary, this patent uses a Z-shaped frame longitudinal beam 1 and a variable-section frame cross beam 2, which, compared with conventional structures, achieves that the upper tank body can be arranged at a significantly lower height without increasing costs or reducing the strength of the frame structure. This frame beam structure is particularly suitable for tank trucks with round tank bodies, can effectively reduce the center of gravity height, increase the roll stability angle of the tank truck, and improve the driving stability and safety of the tank truck, and has good market application prospects.

[0023] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
