Description

Technical Field

[0001] The utility model relates to the field of a rear leaf spring rear lifting ear bracket for a light truck, in particular to a rear leaf spring rear lifting ear bracket. Background Art

[0002] A leaf spring, also known as a leaf spring, is a flat spring composed of at least one sheet of spring steel stacked together. Commonly used in wheeled vehicle suspensions, leaf springs were originally called laminated or bracket springs, and sometimes semi-elliptical or cart springs. They are one of the oldest spring types, dating back to the Middle Ages. In light truck suspension systems, leaf spring lug brackets serve as mounting points for the leaf springs. Existing leaf spring lug brackets are cast in one piece, and during installation, connecting posts are used to connect the lug brackets and leaf springs through holes. This connection method lacks stability and can cause the posts to fall off, resulting in low safety. Furthermore, existing installation methods rely solely on connecting posts, which have weak compressive strength and are prone to breakage. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a rear leaf spring rear hanging ear bracket.

[0004] According to the technical solution provided in the embodiment of the present application, the rear leaf spring and rear lifting ear bracket include a lifting ear connecting plate, the two lifting ear connecting plates are connected by an upper connecting column and a lower connecting column, and an adjustable connecting column is provided on the lifting ear connecting plate. The adjustable connecting column can be raised and lowered on the lifting ear connecting plate through an adjusting device to adjust the distance between the lifting ear and the lower connecting column.

[0005] Furthermore, one end of the upper connecting column and the lower connecting column is fixedly connected to a lifting ear connecting plate, and the other end of the upper connecting column and the lower connecting column passes through another lifting ear connecting plate and is fixed by bolts, which facilitates the disassembly and installation of the upper connecting column and the lower connecting column.

[0006] Furthermore, a hole is provided on the lifting ear connecting plate, one end of the adjustable connecting column is movable through the hole through a limiting ring, and the other end is fixed to the lifting ear connecting plate by a bolt, so as to facilitate the up and down adjustment of the adjustable connecting column.

[0007] Furthermore, the adjusting device includes a stud and a fixed arc plate. The fixed arc plate is located in the hole. The stud passes through the lower end of the ear connecting plate through a thread and is connected to the fixed arc plate, so that the adjustable connecting column can be fixed while being raised and lowered.

[0008] Furthermore, the end surface of the fixed arc plate abuts against the adjustable connecting column.

[0009] Furthermore, a mounting base is provided on the lifting eye connecting plate to strengthen the connection between the lifting eye connecting plate and the vehicle body.

[0010] To sum up, the beneficial effects of the present application are: the device of the present application is connected to the leaf spring ear through the lower connecting column, and an adjustable connecting column is arranged below the connecting column, which together with the lower connecting column bears the vibration force from the leaf spring, making the connection between the ear bracket and the leaf spring more stable.

[0016] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] Rear leaf spring rear hanging eye bracket, such as Figure 1 and Figure 2 As shown, the right end faces of the upper connecting column 2 and the lower connecting column 3 are fixed to the lifting ear connecting plate 1 located at the right end, and the lifting ear connecting plate 1 located below the lower connecting column 3 is provided with an adjustable connecting column 4, and the right ends of the upper connecting column 2, the lower connecting column 3 and the adjustable connecting column 4 are different after passing through the lifting ear connecting plate 1 located on the right side and are fixed by bolts, and the right end parts of the upper connecting column 2, the lower connecting column 3 and the adjustable connecting column 4 are provided with threads;

[0019] like Figure 1 、 Figure 2 and Figure 3As shown, a hole 11 is provided at the lower end of the lifting ear connecting plate 1, and the right and left ends of the adjustable connecting column 4 are movable through the hole 11. A limiting ring is fixedly provided on the right end surface of the adjustable connecting column 4. The diameter of the limiting ring is larger than the width of the hole 11. The left end of the adjustable connecting column 4 is fixed to the lifting ear connecting plate 1 by a bolt.

[0020] At the lower end of the lifting ear connecting plate 1, the stud 51 on the adjusting device 5 is threaded through the lifting ear connecting plate 1 and connected to the fixed arc plate 52 located in the hole 11. In order to prevent the fixed arc plate 52 from rotating with the stud 51 when the stud 51 rotates, the stud 51 is fixedly connected to the fixed arc plate 52 through a bearing.
