Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a primary filter bracket assembly and a dump truck. Background Art

[0002] A primary filter is a filtering device used to intercept large particles to improve the air quality or oil quality entering the subsequent filter, reduce the maintenance cycle of the subsequent filter and extend its service life. The primary filter is generally installed on the vehicle frame through a bracket to match different vehicle models. However, the primary filter bracket generally does not have a protection structure. When the working environment is harsh, the primary filter is easily damaged by flying stones, soil blocks, etc.

[0003] Currently, there has emerged a primary filter with a protection structure (such as the publication number CN214420215U). The primary filter includes a fuel primary filter protection cover, a fuel primary filter protection cover bracket, a hinge and a buckle. The fuel primary filter protection cover bracket and the fuel primary filter protection cover are connected by a hinge. The primary filter is installed on the fuel primary filter protection cover bracket, so that the fuel primary filter is in a closed state for a long time. When the vehicle is running, since the protection cover surrounds the fuel primary filter on all sides, the fuel primary filter can be protected from the impact of flying objects to ensure the normal operation of the primary filter.

[0004] Since the vehicle frame includes a vehicle frame cross beam, in order to avoid the vehicle frame cross beam and improve the layout flexibility, most of the existing primary filter brackets with protection covers are provided with transition brackets. The protection cover bracket is connected to the transition bracket by bolts and is connected to the vehicle frame by using the transition bracket. The setting of the transition bracket results in a complex overall structure of the primary filter bracket and inconvenient installation and use. Summary of the Utility Model

[0026] In order to make the purpose, features, and advantages of the present invention more obvious and understandable, the technical solutions in the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this patent.

[0027] Example 1

[0028] In a typical implementation of the present utility model, as Figures 1 - 3 shown, a coarse filter bracket assembly is proposed, including: a mounting bracket 2 and a shield 6. The mounting bracket 2 is used for detachably mounting on the vehicle frame 1. The mounting bracket 2 has a mounting portion 8 for mounting the coarse filter 5. The shield 6 is detachably mounted on the mounting bracket 2 to cover and protect the coarse filter 5.

[0029] As Figure 2 shown, the mounting bracket 2 is a Z-shaped structure. The mounting bracket 2 includes two parallel and non-coplanar connecting surfaces. The two connecting surfaces are arranged vertically, and a plurality of through holes are provided on the connecting surfaces for connecting with the vehicle frame 1, the coarse filter, and the shield 6. The Z-shaped structure is convenient for avoiding structures such as vehicle frame crossbeams, ensuring the flexibility of the layout of the mounting bracket 2.

[0030] Specifically, the mounting bracket 2 includes a fixing portion 7 and a mounting portion 8. Both the fixing portion 7 and the mounting portion 8 are plate-like structures. The connecting surfaces are arranged on the fixing portion 7 and the mounting portion 8. The fixing portion 7 is located at the rear side below the mounting portion 8, so that the fixing portion 7 is located below the mounting portion 8. The fixing portion 7 is parallel to the mounting portion 8, and the fixing portion 7 and the mounting portion 8 are in different vertical planes. The fixing portion 7 and the mounting portion 8 are fixedly connected by an inclined plate. The inclined plate is fixedly connected to the fixing portion 7 and the mounting portion 8 by means of bending, welding or integral forming. The corners of the fixing portion 7 and the mounting portion 8 are rounded structures to reduce the risk of scratching, and can reduce stress concentration generated by collision at the corners, thereby reducing the risk of sheet metal breakage and enhancing its durability and service life.

[0031] A plurality of mounting through holes are provided on both the fixing portion 7 and the mounting portion 8 for the installation of bolts. Specifically, a plurality of first through holes 9 are provided on the fixing portion 7, and the fixing portion 7 can be fixedly connected to the vehicle frame 1 by bolts; a plurality of second through holes 10 and a plurality of third through holes 11 are provided on the mounting portion 8. Among them, there are two groups of second through holes 10, and the two groups of second through holes 10 are arranged oppositely. The third through holes 11 are located between the two groups of second through holes 10. The second through holes 10 are used for the installation of the shield 6, and the third through holes 11 are used for the installation of the coarse filter 5.

[0032] The design of the Z-shaped mounting bracket 2 eliminates the use of a transition bracket, reduces the number of overall components of the shield bracket, simplifies the complexity of the overall structure, and while ensuring the flexibility of the bracket layout, also facilitates the installation and use of the bracket.

[0033] To further improve the installation flexibility of the bracket, the center line of the fixing part 7 and the center line of the installation part 8 are located in the same vertical plane, and the size of the fixing part 7 is smaller than that of the installation part 8, so as to reduce the installation area of the fixing part 7 and reduce the limitation of the installation space for the fixing part 7, which is convenient for adjusting the installation position of the fixing part 7.

[0034] As Figure 3 shown, the shield 6 is an arc-shaped cover structure. An ear plate is fixedly provided on each side of the upper end of the shield 6. A fourth through hole 12 is formed in the ear plate, and the fourth through holes 12 correspond to the second through holes 10 one by one, so as to fixedly connect the shield 6 and the installation part 8 together by bolts, and cover and protect the coarse filter 5 through the shield 6.

[0035] In this embodiment, both the upper and lower ends of the shield 6 are open structures to facilitate the pipeline to pass through. In other embodiments, the lower end of the shield 6 can also be set to a semi-closed state, that is, a baffle is fixedly provided, and a hole for the pipeline to pass through is formed in the baffle, so as to ensure the shielding protection of the lower end of the coarse filter 5 while avoiding the obstruction of the pipeline layout.

[0036] To improve the service life of the installation bracket 2 and the shield 6, the surfaces of the installation bracket 2 and the shield 6 are treated with an electrophoretic process to fixedly set a paint film layer on their surfaces, and the thickness range of the paint film layer is 30-35 mm.

[0037] Embodiment 2

[0038] In another typical implementation manner of the present utility model, as Figure 1 shown, a dump truck is proposed, which adopts the coarse filter bracket assembly mentioned in Embodiment 1. The dump truck further includes a vehicle frame 1. A long circular hole 13 is formed in the longitudinal beam of the vehicle frame 1 for the penetration of the pipeline of the coarse filter 5. A urea tank 3 is fixedly installed on the vehicle frame 1. The coarse filter 5 is fixedly installed on the vehicle frame 1 through the bracket assembly, and the coarse filter 5 is located in front of the urea tank 3 (with reference to the vehicle traveling direction).

[0039] There is a gap between the coarse filter 5 and the adjacent wheel 4. Specifically, when the wheel 4 is in a steering state, the minimum gap between the wheel 4 and the adjacent coarse filter 5 is ≥50 mm to avoid collision interference between the coarse filter 5 and the wheel 4.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
