[0001] The present invention relates to the technical field of commercial vehicles. Specifically, it relates to an integrated layout structure for a tractor and the tractor thereof. Background Art

[0002] With the development of the economy and the continuous improvement of transportation efficiency, the demand for the driving range and lightweight of tractors is increasing day by day. The dual fuel tank and lightweight requirements have become an inevitable trend in the development of tractors. However, with the implementation of the National VI emission regulations, the size and weight of the after-treatment have increased significantly compared with those of the National V. Due to the current wheelbase limitation and accessory layout of tractors, it can no longer meet the space requirements of the dual fuel tank. Therefore, it is urgent to arrange accessories such as the battery box and air storage tank in other positions of the vehicle to meet the chassis space requirements of the dual fuel tank. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides an integrated layout structure for a tractor, which fixedly connects the battery box to the rear part of the frame longitudinal beam and fixedly connects the air storage tank to the bottom of the battery box, effectively saving the layout space.

[0004] The present invention adopts the following technical solutions to solve the technical problems:

[0005] An integrated layout structure for a tractor includes a frame longitudinal beam, a tail beam assembly, a battery box and an air storage tank. The tail beam assembly is fixedly connected to the rear end of the frame longitudinal beam. The battery box is fixedly connected to the rear part of the frame longitudinal beam. The tail beam assembly, the battery box and the frame longitudinal beam enclose a closed rigid body. The air storage tank is fixedly connected to the bottom of the battery box.

[0006] Further, the tail beam assembly includes a tail beam main body and connection structures symmetrically arranged at both ends of the tail beam main body. The connection structures are fixedly connected to the frame longitudinal beam. The connection structure includes a first connection plate, a second connection plate and a third connection plate fixedly arranged on the tail beam main body. The first connection plate has an upper connection surface and a side connection surface. The upper connection surface is fixedly connected to the upper wing surface of the longitudinal beam. The side connection surface of the first connection plate, the second connection plate and the third connection plate are all fixedly connected to the web surface of the longitudinal beam. The structure is reliable, ensuring the stable force at the rear of the frame.

[0007] Further, the connection structure is fixedly connected to the frame longitudinal beam by rivets or bolt-nut assemblies. The total number of connection points between the side connection surface, the second connection plate and the third connection plate and the web surface of the longitudinal beam is at least 8. Preferably, the connection points between the side connection surface and the web surface of the longitudinal beam are arranged in two rows, reducing the stress at the rear end of the frame longitudinal beam and avoiding the risk of fatigue fracture of the frame longitudinal beam.

[0008] Further, the upper connection surface is parallel to the lower wing surface of the tail beam, and the lower wing surface of the tail beam is fixedly connected to the lower wing surface of the longitudinal beam, making the connection of the tail beam assembly stable and reliable.

[0009] Further, the upper connecting surface is connected to the upper wing surface of the tail beam through an inclined surface, and the upper connecting surface is higher than the upper wing surface of the tail beam; the inclined surface and the upper connecting surface have an included angle Φ. Preferably, the included angle Φ is 8°-10°, so as to avoid interference with the vehicle frame during the front and rear roll of the trailer.

[0010] Further, the tail beam assembly is an integral structure, and the tail beam assembly is integrally formed, reducing the weight of the vehicle frame.

[0011] Further, the battery box is connected to the longitudinal beam of the vehicle frame through two symmetrically arranged front brackets and two symmetrically arranged rear brackets, making the battery box firmly fixed.

[0012] Further, the top plate of the battery box includes a flat part and a slope part. The flat part is parallel to the upper wing surface of the longitudinal beam, lower than the upper wing surface of the longitudinal beam, and does not exceed the rear edge of the upper connecting surface of the first connecting plate. The slope part is lower than the inclined surface of the first connecting plate, meeting the layout requirements of the battery box and avoiding interference during the roll of the trailer.

[0013] Further, the bottom plate of the battery box is stepped, with the front side of the step higher than the rear side; the air storage tank includes a first air storage tank and a second air storage tank. The first air storage tank and the second air storage tank are respectively fixed to the front side and the rear side of the step, meeting the air consumption needs of the whole vehicle and meeting the requirements of the departure angle of the whole vehicle and the space for the rear axle to jump.

[0014] Further, a tractor includes the integrated layout structure described above.

[0026] The present invention provides an integrated layout structure for a tractor, in combination with Figure 1 and Figure 2As shown in the figure, it includes the longitudinal frame beam 1, the tail beam assembly 2, the battery box 3 and the air storage cylinder. The tail beam assembly 2 is fixedly connected to the rear end of the longitudinal frame beam 1. The battery box 3 is fixedly connected to the rear part of the longitudinal frame beam 1. The tail beam assembly 2, the battery box 3 and the longitudinal frame beam 1 enclose to form a closed rigid body. The air storage cylinder is fixedly connected to the bottom of the battery box 3. The battery box 3, the air storage cylinder and the tail beam assembly 2, as the tail module, effectively save the overall vehicle layout space, provide enough space for arranging double fuel tanks after the post-treatment is increased in the National VI standard, solve the problem that double fuel tanks cannot be arranged due to limited layout space, thereby improving the vehicle's cruising range and enhancing the product competitiveness. The battery box 3, the longitudinal frame beam 1 and the tail beam assembly 2 form a closed rigid structure, improving the stiffness and strength of the frame tail, and the overall structure is reliable.

[0027] Specifically, referring to Figures 1 - 3 As shown in the figure, the tail beam assembly 2 includes a tail beam main body and connection structures symmetrically arranged at both ends of the tail beam main body. The connection structures are fixedly connected to the longitudinal frame beam 1. The connection structures include a first connecting plate 24, a second connecting plate 25 and a third connecting plate 26 fixedly arranged on the tail beam main body. The first connecting plate 24 has an upper connecting surface 241 and a side connecting surface 242. The longitudinal frame beam 1 includes a longitudinal beam upper wing surface 11, a longitudinal beam web surface 12 and a longitudinal beam lower wing surface 13. The upper connecting surface 241 is fixedly connected to the longitudinal beam upper wing surface 11. The side connecting surface 242 of the first connecting plate 24, the second connecting plate 25 and the third connecting plate 26 are all fixedly connected to the longitudinal beam web surface 12. The longitudinal frame beam 1 is of a trough type, and the connection structures as a whole form a trough type. During assembly, the connection structures at both ends are respectively inserted into the troughs of the longitudinal frame beams 1 on both sides, the upper connecting surface 241 is fixedly connected to the longitudinal beam upper wing surface 11, and the side connecting surface 242, the second connecting plate 25 and the third connecting plate 26 are all fixedly connected to the longitudinal beam web surface 12, so that the tail beam assembly 2 can be reliably fixed on the longitudinal frame beam 1, with a stable and reliable structure, and can ensure stable force at the frame tail. It can be understood that the fixed connection includes fixed connection methods such as welding and riveting, and also includes detachable connection methods such as threaded connection.

[0028] When the connecting structure is fixedly connected to the longitudinal beam 1 of the vehicle frame by rivets 6 or bolt-nut assemblies 7, the total number of connection points between the side connection surface 242, the second connecting plate 25, and the third connecting plate 26 and the web surface 12 of the longitudinal beam is at least 8. For example, it can be set to 8, 9, 10, 11, 12, etc. Specifically, the connection points are through holes provided corresponding to the vehicle frame longitudinal beam 1 and each connection surface for the rivets 6 and bolts to pass through. Preferably, the side connection surface 242 is relatively wide and long, and the connection points between the side connection surface 242 and the web surface 12 of the longitudinal beam are arranged in two staggered rows, with 3 through holes arranged horizontally in each row. The second connecting plate 25 can be provided with 2 through holes longitudinally, and the third connecting plate 26 can be provided with 3 through holes horizontally. Correspondingly, 11 through holes are provided on the web of the vehicle frame longitudinal beam 1. In addition, through holes are also provided corresponding to the upper connection surface 241 and the upper wing surface 11 of the longitudinal beam, and the upper connection surface 241 is fixedly connected to the upper wing surface 11 of the longitudinal beam by rivets 6 or bolt-nut assemblies 7. In this way, by setting multiple connection points, the tail beam assembly 2 is fixedly connected to the vehicle frame longitudinal beam 1, which can reduce the stress at the rear end of the vehicle frame longitudinal beam 1 and avoid the risk of fatigue fracture of the vehicle frame longitudinal beam 1. More preferably, the upper connection surface 241 is arranged parallel to the lower wing surface 23 of the tail beam, and the lower wing surface 23 of the tail beam is fixedly connected to the lower wing surface 13 of the longitudinal beam, making the connection of the tail beam assembly 2 more stable and reliable.

[0029] The tail beam body includes a tail beam upper wing surface 21, a tail beam web surface 22, and a tail beam lower wing surface 23. The front end of the tail beam assembly 2 is higher than the rear end. The upper connection surface 241 is connected to the tail beam upper wing surface 21 through an inclined surface 243, and the upper connection surface 241 is higher than the tail beam upper wing surface 21; the inclined surface 243 and the upper connection surface 241 have an included angle Φ. Preferably, the included angle Φ is 8° - 10°, which can avoid interference with the vehicle frame during the front and rear roll of the trailer and fully ensure the swing space of the trailer.

[0030] The tail beam assembly 2 can be integrally formed by integral stamping. The tail beam upper wing surface 21, the tail beam web surface 22, and the tail beam lower wing surface 23 are stamped into a trough shape. The first connecting plate 24 extends backward from the tail beam upper wing surface 21 and then bends downward. The second connecting plate 25 bends backward and extends from the tail beam web. The third connecting plate 26 bends upward and extends from the tail beam lower wing surface 23, making the tail beam assembly 2 form an integral structure. The integral forming of the tail beam assembly 2 has a simple structure, reduces the weight of the vehicle frame, and the weight is reduced by about 42% compared with the traditional split product, improving the lightweight level of the whole vehicle.

[0031] Reference Figure 1 and Figure 2As shown, the battery box 3 is connected to the longitudinal frame beam 1 through two symmetrically arranged front brackets 41 and two symmetrically arranged rear brackets 42. Preferably, the front brackets 41 and the rear brackets 42 are the same. The battery box 3 is connected to the longitudinal frame beam 1 through four front and rear brackets, making the battery box 3 firmly fixed and reliable, and reducing the types of brackets, which is convenient for assembly.

[0032] The top plate 31 of the battery box 3 includes a flat part 311 and a slope part 312. The flat part 311 is parallel to the upper wing surface 11 of the longitudinal beam and lower than the upper wing surface 11 of the longitudinal beam, and does not exceed the rear edge of the upper connection surface 241 of the first connecting plate 24. The slope part 312 is lower than the inclined surface 243 of the first connecting plate 24. The rear part of the battery box 3 is parallel to the outer boundary of the rear end of the longitudinal frame beam 1 and does not exceed the outer boundary of the rear end of the longitudinal frame beam 1. In this way, the battery box 3 is arranged between the two longitudinal frame beams 1 and the tail beam assembly 2, meeting the layout requirements of the battery box 3 and avoiding interference during the roll of the trailer, and fully ensuring the swing space of the trailer.

[0033] Reference Figure 1 and Figure 4 As shown, the front side of the battery box 3 is high and the rear side is low. Correspondingly, the bottom plate 32 of the battery box 3 can be set in a stepped shape, with the front side of the step higher than the rear side of the step. The battery box 3 is integrally in an L shape, which can meet the installation needs of the battery inside the box. The air storage tank includes a first air storage tank 51 and a second air storage tank 52. The first air storage tank 51 and the second air storage tank 52 are fixedly arranged on the front side and the rear side of the step in sequence. For example, the first air storage tank 51 and the second air storage tank 52 can be detachably hung on the front side and the rear side of the step through a hoop band 53. The front and rear steps of the bottom plate 32 of the battery box 3 hang two air storage tanks, which can meet the air consumption requirements for the vehicle braking and meet the requirements of the vehicle departure angle and the space for the rear axle bounce. The layout form of arranging the battery box 3 at the rear and fixing the air storage tank at the bottom of the battery box 3 constitutes a modular integrated structure, effectively saving the chassis layout space, and the battery box 3 and the air storage tank can be assembled onto the whole vehicle at one time, with convenient installation and disassembly, improving the assembly efficiency of the whole vehicle.
