Description

Technical Field

[0001] The utility model relates to the technical field of leaf spring connection equipment, in particular to a leaf spring hanging bracket. Background Art

[0002] Automobile leaf springs are composed of main leaves and auxiliary leaves. The main leaves are used to connect the axle and the frame, and to bear the supporting force, traction, braking force and lateral force exerted by the axle on the frame, thereby reducing the impact of the vehicle during driving. The longest leaf in the main leaf spring has its ends bent to form ears, with bushings installed inside, and is hinged to the hanging bracket on the frame using spring pins. The supporting force, traction, braking force and lateral force exerted by the axle on the frame will be transmitted to the hanging bracket through the leaf spring.

[0003] For example, the publication number CN219467487U disclosed a front leaf spring hanging ear bracket on August 4, 2023, comprising a hanging ear body and a main body, a frame mounting portion being provided on the top of the main body, hanging ear connecting portions being symmetrically provided on both sides of the bottom of the main body, connecting tubes being fixed inside the hanging ear connecting portions on both sides, a support member being fixedly connected to the top of the connecting tube axis center, connecting shafts being provided at both ends of the connecting tube, and a rotational connection between the connecting shaft and the hanging ear body, the main body cross-section being an inverted isosceles trapezoidal structure, and the edges and corners being chamfered, a gasket being provided on the top of the frame mounting portion, and the support member and the main body being connected and fixed by welding. When the hanging bracket disclosed above is installed on the vehicle body, it is only connected to the lower end of the longitudinal beam of the vehicle body. The installation of the hanging bracket is not stable enough and is prone to falling off, resulting in poor practicality. Summary of the Invention

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0027] like Figure 1-5 As shown, the leaf spring suspension bracket includes a main board 1 and side boards 2. The main board 1 and the side boards 2 are connected to the longitudinal beams of the vehicle body. The side boards 2 are arranged on both sides of the main board 1. A notch 3 is provided at the connection position between the side boards 2 and the main board 1. Specifically, two side boards 2 are provided, and the side boards 2 are symmetrically arranged on both sides of the length direction of the main board 1.

[0028] When in use, the bottom of the vehicle body longitudinal beam is welded to the main board 1, and the side of the vehicle body longitudinal beam is welded to the side panel 2, so as to achieve stable installation of the hanging bracket, thereby improving the ability of the entire bracket to resist vertical and lateral impact loads, thereby achieving stable installation of the leaf spring connected to the hanging bracket.

[0029] The main board 1 and side panel 2 are sheet metal stamping and bending parts. The integrated sheet metal stamping and bending is used to eliminate the influence of welding defects, and the reliability is high. The slope of the side panel 2 and the vertical direction is 5°. The setting of the slope facilitates the demolding of the entire bracket after stamping.

[0030] The side panel 1 and the two side panels 2 are combined into a box body. A bushing mounting hole 4 is provided on one side panel 2. The bushing mounting hole 4 is used to install the leaf spring ear bushing. The box body structure has extremely high structural rigidity, which can effectively resist the supporting force, traction, braking force and lateral force of the axle acting on the frame, and prevent the hanging bracket from deforming under the above loads. The slot 3 provided between the side panel 2 and the main board 1 prevents the side panel 2 from interfering when bending, thereby realizing convenient forming of the hanging bracket and higher practicality. The slot 3 is provided at the lowest position of the main board 1, so that the liquid can flow out along the slot 3, preventing the liquid from being retained for a long time and causing corrosion of the bracket.

[0031] The main board 1 includes a base plate 101, support plates 102 are provided at both ends of the base plate 101, and a first welding plate 103 welded to the vehicle body longitudinal beam is provided on the support plate 102. The two first welding plates 103 are welded to the vehicle body longitudinal beam, thereby realizing the connection of the entire hanging bracket, so that the support plate 102 supports the first welding plate 103. Specifically, the side panels 2 are arranged on both sides of the base plate 101, and the two support plates 102 are arranged at both ends of the base plate 101, and the two first welding plates 103 are arranged on the support plate 102, thereby ensuring that the side panels 2, the base plate 101, the support plate 102 and the first welding plate 103 form a box body, thereby performing a stably connected work with the vehicle body longitudinal beam.

[0032] There is an inclination between the support plate 102 and the bottom plate 101, and there is an inclination between the support plate 102 and the first welding plate 103. The first welding plate 103 and the bottom plate 101 are parallel to each other, so as to ensure that when the vehicle body longitudinal beam is overlapped on the two first welding plates 103, a triangular structure is formed between the two support plates 102 and the vehicle body longitudinal beam. The triangular structure has good impact resistance and can effectively resist impact loads when the vehicle is running under harsh working conditions. Specifically, the end of the bottom plate 101 is bent upward by 45° to form the support plate 102, and the support plate 102 is bent downward by 45° to form the first welding plate 103.

[0033] The first welding plate 103 is provided with a positioning hole 5 , which is a positioning hole when the leaf spring hanger bracket is welded to the vehicle frame to ensure the correctness of the welding position. Specifically, the positioning hole 5 is set in the middle position of the first welding plate 103 .

[0034] A first reinforcing rib 6 is provided between the support plate 102 and the base plate 101, and a second reinforcing rib 7 is provided between the support plate 102 and the first welding plate 103. Through the structure of the first reinforcing rib 6 and the second reinforcing rib 7, the structural rigidity of the main board 1 is increased, and the ability of the entire bracket to resist vertical impact loads is improved.

[0035] The side panel 2 is Z-shaped and is provided with a second welding plate 8 welded to the vehicle body longitudinal beam. The second welding plate 8 is welded to the vehicle body longitudinal beam, thereby realizing the welding of the side panel 2 and the vehicle body longitudinal beam, thereby improving the ability to resist lateral loads. Specifically, there are two second welding plates 8, and the two second welding plates 8 are symmetrically arranged on the two side panels 2, and an inclination is provided between the second welding plate 8 and the side panel 2, thereby realizing the Z-shape of the entire side panel 2.

[0036] The second welding plate 8 is provided with ribs 9, which improve the structural rigidity of the side plate 2 and prevent the side plate from deforming when subjected to a lateral load. Specifically, two ribs 9 are provided, and the two ribs 9 are symmetrically arranged on the second welding plate 8.

[0037] A lap plate 10 is provided on the side panel 2, which is overlapped with the support plate 102 and connected by argon arc welding to improve the torsional resistance of the side panel 2. Specifically, each side panel 2 is provided with two lap plates 10, and the four lap plates 10 are welded together with the support plate 102 on the bottom plate 1.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
