Description

Technical Field

[0001] The utility model relates to a wide-body vehicle, in particular to an integral crossbeam support suspension structure for a cab platform of a pure electric wide-body vehicle. Background Art

[0002] Currently, the rear end of the cab platform is connected to the crossbeam structure near the front suspension position by bolts, such as the crossbeam bracket assembly for wide-body vehicles and engineering machinery disclosed in Chinese Patent Publication No. CN 219619216 U. The crossbeam bracket assembly includes a left bracket configured to be cantilevered and fixed to the left longitudinal beam of the wide-body vehicle frame, a right bracket configured to be cantilevered and fixed to the right longitudinal beam of the wide-body vehicle frame, and an intermediate crossbeam, the intermediate crossbeam being overlapped and connected to the left and right brackets at both ends. The crossbeam bracket adopts a segmented crossbeam structure, and the crossbeam itself is an open "U"-shaped welded structure. On the one hand, it is to increase the vertical space of the frame longitudinal beam to ensure that there is sufficient space for the arrangement of related equipment. On the other hand, the left and right frames are connected by the crossbeam structure to form a ring beam structure to increase the overall rigidity of the frame. The segmented crossbeam structure is a frame-type welded structure with a large amount of welding, and its structure itself is relatively easy to deform. At the same time, considering that different equipment will inevitably be installed on both sides of the frame connected by the crossbeam, when the segmented crossbeam is subjected to force, the cross-section of the crossbeam structure and the cross-section of the structure on both sides of the beam are quite different, resulting in inconsistent deformation of the overall structure, thereby increasing the comprehensive force on the connecting bolts, which may cause the crossbeam connecting bolts to break under extreme working conditions. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an integral crossbeam support and suspension structure for the cab platform of a pure electric wide-body vehicle. By adopting the integral crossbeam structure, the overall equipment layout is more reasonable, and the material specifications are reduced as a whole, thereby reducing material costs. The main structure is symmetrical and complies with the equal strength design principle. The integral support and suspension structure deforms evenly after being subjected to force.

[0004] In order to solve the above technical problems, the technical solution of the present utility model is: an integral crossbeam support and suspension structure for the cab platform of a pure electric wide-body vehicle, comprising an integral crossbeam, fenders arranged at the bottom of both ends of the integral crossbeam, and crossbeam mounting seats for connecting to the vehicle frame arranged on the left and right sides of the middle bottom of the integral crossbeam; a cab mounting seat is provided at the top of the left end of the integral crossbeam, an electrical cabinet mounting seat is provided at the middle top of the integral crossbeam, a valve group mounting seat is provided at the middle bottom of the integral crossbeam, a water-cooling unit mounting seat is provided at the top of the right end of the integral crossbeam, a platform mounting seat is provided on the right end side of the integral crossbeam, and platform mounting holes are provided on the platform mounting seat and on the integral crossbeam. Principle of the present utility model: the use of an integral crossbeam structure makes the overall equipment layout more reasonable, and reduces the material specifications and reduces the material cost as a whole; the main structure is symmetrical and complies with the equal strength design principle, and the integral support and suspension structure deforms evenly after being subjected to force.

[0005] As an improvement, the integral crossbeam is a U-shaped bent crossbeam with its notch facing.

[0006] As an improvement, a middle crossbeam cover plate is welded to the middle bottom of the integral crossbeam, and the crossbeam mounting seat and the valve group mounting seat are fixed on the middle crossbeam cover plate.

[0007] As an improvement, a first reinforcing rib plate is provided between the middle crossbeam cover plate and the side surface of the integral crossbeam.

[0008] As an improvement, the crossbeam mounting seat is L-shaped, comprising a cross plate and a vertical plate, the vertical plate being connected to the frame longitudinal beam by bolts, and the cross plate being connected to the middle crossbeam cover plate by bolts.

[0009] As an improvement, end crossbeam covers are welded to the bottoms of both ends of the integral crossbeam, and the fenders are fixed to the end crossbeam covers by bolts.

[0010] As an improvement, a second reinforcing rib plate is provided between the end crossbeam cover plate and the integral crossbeam.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The integral U-shaped bent beam with uniform cross section and the segmented beam cover are welded together to form an integral beam support suspension structure. The main structure is symmetrical, in line with the equal strength design principle. The integral support suspension structure deforms evenly after being subjected to stress.

[0013] 2. The use of an integral beam structure makes the overall equipment layout more reasonable, reduces the overall material specifications and reduces material costs;

[0014] 3. The integral beam support suspension structure adopts the form of welding U-shaped bent beams and segmented beam covers, which not only ensures the structural strength and rigidity, but also reduces the weld length and effectively avoids deformation caused by welding;

[0015] 4. The integral crossbeam support suspension structure adopts the form of welding U-shaped bent crossbeam and segmented cover plate, and adopts the middle part to change the two longitudinal beams across the frame, thus forming a ring beam structure with the frame. At the same time, it forms a structural redundancy design with the original front ring beam structure, effectively increasing the overall torsional stiffness and structural strength of the frame, and increasing the service life of the frame structure.

[0019] like Figure 1 、 2 As shown, a fully electric wide-body vehicle cab platform integral crossbeam support and suspension structure comprises an integral crossbeam 1, fenders 2 disposed at the bottom ends of the integral crossbeam 1, and crossbeam mounting brackets 3 disposed on the left and right sides of the center bottom of the integral crossbeam 1 for connecting to the vehicle frame. A cab mounting bracket 4 is provided at the top of the left end of the integral crossbeam 1, an electrical cabinet mounting bracket 5 is provided at the center top of the integral crossbeam 1, a valve assembly mounting bracket 6 is provided at the center bottom of the integral crossbeam 1, a water-cooling unit mounting bracket 7 is provided at the top of the right end of the integral crossbeam 1, and a platform mounting bracket 8 is provided on the side of the right end of the integral crossbeam 1. Platform mounting holes are provided on the platform mounting bracket 8 and on the integral crossbeam 1. The use of the integral crossbeam 1 structure makes the overall equipment layout more reasonable, reduces material specifications, and reduces material costs. The main structure is symmetrical, conforming to the principle of equal strength design, and the integral support and suspension structure deforms evenly when subjected to force. The left side of the integral crossbeam 1 supporting the suspension structure is the installation position of the cab assembly, which is connected to the integral crossbeam 1 by bolts and is equipped with a vibration reduction mechanism; the middle is the installation position of the integral electrical cabinet, which is connected by bolts and is equipped with a vibration reduction mechanism; the valve group installation position is below the integral crossbeam 1, and the valve group mounting seat 6 and the middle crossbeam cover are welded to form a whole, and the valve group is connected to the mounting seat by bolts; the right side is the installation position of the platform and the integrated water-cooling unit, which are connected to the crossbeam by bolts and are also equipped with a vibration reduction mechanism.

A central crossbeam cover plate 9 is welded to the middle bottom of the integral crossbeam 1, to which the crossbeam mounting seat 3 and valve assembly mounting seat 6 are fixed. A first reinforcing rib 10 is provided between the central crossbeam cover plate 9 and the side of the integral crossbeam 1. End crossbeam covers 11 are welded to the bottom of each end of the integral crossbeam 1, to which the fender 2 is bolted. A second reinforcing rib 12 is provided between the end crossbeam covers 11 and the integral crossbeam 1. The integral crossbeam 1 is welded together by welding a U-shaped bent crossbeam and a central crossbeam cover plate 9. The first reinforcing rib 10 is added at the mounting position, forming a frame structure in the middle of the frame longitudinal beam. This ensures the structural strength and torsional rigidity of the integral crossbeam 1 while increasing the mounting area for the crossbeam mounting seats 3 on both sides of the frame. The fender 2 and the end cross beam cover 11 have the same thickness and are disconnected in the middle. The fender 2 and the end cross beam cover 11 are combined to form a segmented cover of a U-shaped bent cross beam.

The vertical plate is bolted to the frame longitudinal beam 13, and the horizontal plate is bolted to the central crossbeam cover plate 9. The integral crossbeam 1 is bolted to the crossbeam mounting base 3 on both sides of the frame. The crossbeam mounting base 3 is a welded structure, formed by welding an L-shaped bent plate and two vertical plates. The left and right crossbeam mounting bases 3 are bolted to the frame longitudinal beams, forming a ring beam structure with the frame longitudinal beams.
