[0037] The leaf spring bracket 1 according to an embodiment of the present invention will be described below with reference to the drawings.

[0038] As Figures 1 - 4 shown, a leaf spring bracket 1 according to an embodiment of the present invention is provided, which is characterized by including: a vehicle frame mounting portion 100, a leaf spring connecting portion 200, and a post-treatment mounting plate 300.

[0039] The frame mounting portion 100 is configured with a plurality of frame mounting hole portions 110 and upper connecting ribs 120 connecting the frame mounting hole portions 110. The frame mounting hole portions 110 are arranged in multiple rows and columns. The upper connecting ribs 120 connect the frame mounting hole portions 110 to form a rectangular first hollow hole 11. The leaf spring connecting portion 200 is configured with a leaf spring connecting hole portion 210 and a plurality of lower connecting ribs 220. The plurality of lower connecting ribs 220 are connected to the frame mounting hole portions 110 and the leaf spring connecting hole portion 210. The plurality of lower connecting ribs 220 are arranged at intervals, and a triangular second hollow hole 12 is formed between the plurality of lower connecting ribs 220. The aftertreatment mounting plate 300 is adapted to mount the aftertreatment assembly. The aftertreatment mounting plate 300 includes a main body portion 310 and an upper connecting arm 320, a first lower connecting arm 330, and a second lower connecting arm 340 connecting the main body portion 310. The upper connecting arm 320 is connected to the upper connecting rib 120. The first lower connecting arm 330 and the second lower connecting arm 340 are located below the upper connecting arm 320. The first lower connecting arm 330 and the second lower connecting arm 340 are respectively connected to the front and rear sides of the main body portion 310 and are respectively connected to one of the lower connecting ribs 220.

[0040] For example, the frame mounting hole portion 110 and the leaf spring connecting hole portion 210 are configured as cylinders. The axes of the plurality of frame mounting hole portions 110 and the leaf spring connecting hole portion 210 all extend in the horizontal direction. The frame mounting hole portion 110 is provided with a bolt for mounting on the frame. The leaf spring connecting hole portion 210 is rotatably mounted with a sling 40, and a leaf spring 20 is mounted at the bottom of the sling 40. Among them, a bushing 30 is provided inside the leaf spring connecting hole portion 210, and one end of the leaf spring is kept mounted through the sling 40 inside the bushing 30. The plurality of frame mounting hole portions 110 are arranged in an array, and the intervals in each row and each column are equal. The upper connecting ribs 120 connect the frame mounting hole portions 110 in each row and each column to form a neat rib structure. The aftertreatment mounting plate 300 extends outwardly from the side surfaces of the frame mounting portion 100 and the leaf spring connecting portion 200 perpendicular to the frame longitudinal beam 10, and the aftertreatment assembly (not shown in the figure) is mounted outside the frame.

[0041] The leaf spring bracket 1 according to an embodiment of the present invention connects the upper connecting rib 120 to the vehicle frame mounting portion 100 and the lower connecting rib 220 to the leaf spring connecting portion 200. Without setting an additional strengthening structure, the structure is lighter and more beautiful. Moreover, the upper connecting rib 120 and the lower connecting rib 220 are connected to the aftertreatment mounting plate 300 through the upper connecting arm 320, and the lower connecting rib 220 is connected to the aftertreatment mounting plate 300 through the first lower connecting arm 330 and the second lower connecting arm 340. The front and rear sides of the upper vehicle frame mounting portion 100 and the lower leaf spring connecting portion 200 are both connected to the aftertreatment mounting plate 300. The first lower connecting arm 330 and the second lower connecting arm 340 are respectively connected to both sides of the front and rear aftertreatment mounting plates 300 and form a U-shaped structure. The first lower connecting arm 330 and the second lower connecting arm 340 are arranged at intervals front and rear, so that the upper connecting arm 320, the first lower connecting arm 330 and the second lower connecting arm 340 form a three-point stable connection structure, ensuring the firm connection of the aftertreatment mounting plate 300. The leaf spring bracket 1 mounts the leaf spring 20 through the leaf spring connection hole portion 210 at the lower part and mounts the aftertreatment assembly through the aftertreatment mounting plate 300, having the function of integrally mounting the leaf spring 20 and the aftertreatment assembly (not shown in the figure), and ensuring a firm structural strength.

[0042] Therefore, for the leaf spring bracket 1 according to an embodiment of the present invention, a hollow structure is formed by the upper connecting rib 120 and the lower connecting rib 220, and the upper connecting rib 120 and the lower connecting rib 220 are respectively connected to the aftertreatment mounting plate 300 through the upper connecting arm 320, the first lower connecting arm 330 and the second lower connecting arm 340, with more stable force, and having the advantages of beautiful appearance, high degree of light weight and high force strength.

[0043] In some specific embodiments of the present invention, as Figure 2 shown, the main body portion 310 includes an aftertreatment upper mounting arm 311 and an aftertreatment lower mounting arm 312. The aftertreatment upper mounting arm 311 and the aftertreatment lower mounting arm 312 are connected on the side facing the vehicle frame mounting portion 100 and the leaf spring connecting portion 200, and the aftertreatment upper mounting arm 311 and the aftertreatment lower mounting arm 312 are arranged at intervals up and down on the side away from the vehicle frame mounting portion 100 and the leaf spring connecting portion 200.

[0044] The main body portion 310 forms a U-shaped structure, and the upper connecting arm 320 is connected to the side of the main body portion 310 facing the vehicle frame longitudinal beam 10, and the first lower connecting arm 330 and the second lower connecting arm 340 are connected to the lower side. The middle part of the main body portion 310 is spaced apart, minimizing the material used for the aftertreatment mounting plate 300, thereby reducing the weight.

[0045] The post-treatment upper mounting arm 311 and the post-treatment lower mounting arm 312 are both provided with bolts for mounting the post-treatment assembly. The bolts of the post-treatment upper mounting arm 311 are arranged at intervals along the length direction of the post-treatment upper mounting arm 311, and the bolts of the post-treatment lower mounting arm 312 are arranged at intervals along the length direction of the post-treatment lower mounting arm 312.

[0046] In some specific embodiments of the present invention, as Figure 3 shown, the thickness of each lower connecting rib 220 gradually increases from the vehicle frame mounting hole portion 110 to the leaf spring connecting hole portion 210.

[0047] Specifically, the opposite side surfaces of the lower connecting rib 220 in the thickness direction of the leaf spring connecting portion 200 gradually approach each other in the direction of the leaf spring connecting hole portion 210. The opposite side surfaces of the lower connecting rib 220 in the thickness direction of the leaf spring connecting portion 200 can both form arcs, and the lower connecting rib 220 forms an arc transition at the connection with the leaf spring connecting hole portion 210, preventing stress concentration and ensuring the stability of the force on the leaf spring bracket 1.

[0048] In some specific embodiments of the present invention, as Figure 4 shown, the leaf spring connecting portion 200 is configured with a reinforcing portion 230 that partially fills the second hollow hole 12. The reinforcing portion 230 is connected to the lower connecting rib 220 and the leaf spring connecting hole portion 210 on the side adjacent to the leaf spring connecting hole portion 210.

[0049] For example, the outer contour of the third hollow hole forms a triangle, and the reinforcing portion 230 partially fills the third hollow hole to form a quadrilateral hollow structure. The thickness of the reinforcing portion 230 is less than the thickness of the lower connecting rib 220. For example, one side surface of the reinforcing portion 230 is flush with the lower connecting rib 220 with a smaller middle thickness, and the lower connecting rib 220 on the other side of the reinforcing portion 230 extends beyond the side surface of the reinforcing portion 230. By partially filling the third hollow hole with the reinforcing portion 230, a reinforcing structure can be formed on one side of the leaf spring connecting hole portion 210, improving the structural strength of the lower connecting rib 220, and further improving the overall structural strength of the leaf spring bracket 1.

[0050] In some specific embodiments of the present invention, as Figure 4 shown, the vehicle frame mounting hole portion 110 includes: a first hole portion 111, a second hole portion 112, a third hole portion 113, a fourth hole portion 114, and a fifth hole portion 115;

[0051] The first hole portion 111 and the second hole portion 112 are located in the first row, the third hole portion 113, the fourth hole portion 114, and the fifth hole portion 115 are located in the second row, and the connecting lines of the first hole portion 111, the second hole portion 112, the third hole portion 113, the fourth hole portion 114, and the fifth hole portion 115 are configured as a rectangle.

[0052] Specifically, the first hole portion 111, the second hole portion 112, the third hole portion 113, the fourth hole portion 114, and the fifth hole portion 115 are arranged in two rows and three columns. The first hole portion 111 and the third hole portion 113 are in the first column, the second hole portion 112 and the fourth hole portion 114 are in the second column, and the fifth hole portion 115 is in the third column. Each frame mounting hole portion 110 is arranged in an array, and the intervals between the frame mounting hole portions 110 in each column and each row are equal, so that a plurality of frame mounting hole portions 110 are arranged to form a neat structure.

[0053] The connecting lines of the first hole portion 111, the second hole portion 112, the third hole portion 113, the fourth hole portion 114, and the fifth hole portion 115 form a rectangle. Specifically, the connecting lines of the center points of the first hole portion 111, the second hole portion 112, the third hole portion 113, the fourth hole portion 114, and the fifth hole portion 115 form a right trapezoid. The upper connecting rib 120 passes through this connecting line, forming a framework structure between adjacent frame mounting hole portions 110, which has a high degree of light weight while having high structural strength.

[0054] Furthermore, as Figure 4 shown, the upper connecting rib 120 includes a transverse connecting rib 121 and a longitudinal connecting rib 122.

[0055] The transverse connecting rib 121 is connected to the first hole portion 111 and the second hole portion 112. The longitudinal connecting rib 122 is connected to the first hole portion 111 and the third hole portion 113, connected to the second hole portion 112 and the fifth hole portion 115, and connected to the transverse connecting rib 121 and the fifth hole portion 115.

[0056] In some specific embodiments of the present invention, as Figure 4 shown, the connecting lines of the third hole portion 113, the fourth hole portion 114, the fifth hole portion 115, and the leaf spring connecting hole portion 210 are configured to form a triangle.

[0057] The third hole portion 113, the fourth hole portion 114, and the fifth hole portion 115 are all connected with a lower connecting rib 220, and the lower connecting ribs 220 connecting the third hole portion 113, the fourth hole portion 114, and the fifth hole portion 115 are all connected to the frame mounting hole portion 110. The lower connecting ribs 220 adjacent to each other and the upper connecting rib 120 above surround to form a triangle. By using the stability of the triangle, the lower connecting ribs 220 on both sides form a strengthening structure to ensure the stability of the leaf spring bracket 1.

[0058] According to some specific embodiments of the present invention, as Figure 2As shown, the thickness between the top surface and the bottom surface of the upper connecting arm 320 gradually increases in the direction from the vehicle frame mounting portion 100 to the main body portion 310. Specifically, the bottom surface of the upper connecting arm 320 extends in the horizontal direction, and the top surface of the upper connecting arm 320 is inclined upward in the direction from the main body portion 310 to the main body portion 310. It adapts to the shapes of the upper connecting rib 120 and the main body portion 310 to ensure the firmness of the connection of the upper connecting arm 320.

[0059] In some specific embodiments of the present invention, the leaf spring bracket 1 is a ductile iron casting. Further, the leaf spring bracket 1 can be selected from grades such as QT500, QT600, QT700, QT800, etc. according to the load-bearing requirements.
