Description

Roller-type external leaf spring Technical Field

[0001] This utility model relates to the field of leaf spring technology, and in particular to a leaf spring with an externally attached coiled ear. Background Technology

[0002] Leaf springs are commonly used cushioning materials in automobiles. Externally mounted leaf springs with rolled lugs involve bending both ends of the leaf spring into an arc shape to provide a suspension mounting method, thus improving the ease of installation. While typical externally mounted leaf springs use suspension to fix the leaf spring, the rolled lugs themselves have openings, which affects the stability of the leaf spring. Furthermore, after prolonged use, impurities easily accumulate at the openings of the rolled lugs. Although the leaf spring may not detach, the accumulated impurities increase the difficulty of disassembling and assembling the suspension, affecting the practicality of the leaf spring. Summary of the Invention

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a rolled-ear external hanging leaf spring, which increases the stability of the hanging leaf spring after installation by using a docking wrapping method, while making it easier for workers to apply external force to the wrapping parts and improving the convenience of removing the rolled-ear hanging leaf spring.

[0004] This utility model also provides a leaf spring with the above-mentioned externally mounted coiled lugs, comprising: a leaf spring body, with arcuate coiled lugs respectively provided on the left and right sides of the leaf spring body; a mounting block fixedly connected to the surface of the leaf spring body; two mating sealing plates slidably connected to the surface of the leaf spring body, the two mating sealing plates being located on the left and right sides of the mounting block; the side of the mating sealing plate away from the mounting block engaging with the arcuate coiled lugs; a spring fixedly connected between the mounting block and the mating sealing plates; a winding rod rotatably connected to the surface of the mounting block, and a groove provided on the upper surface of the mounting block; the winding rod passing through the groove; a wear-resistant rope fixedly connected to the end of the mating sealing plate near the mounting block; the end of the wear-resistant rope away from the mating sealing plate wrapping around the surface of the winding rod; and a weighted tube provided on the surface of the wear-resistant rope near the mounting block and the mating sealing plate.

[0005] According to the externally mounted leaf spring of this utility model, the surface of the arc-shaped rolled ear and the side opposite to the docking sealing plate are respectively provided with a magnetic locking block and a magnetic locking groove. When installing the leaf spring, the magnetic locking block is located inside the magnetic locking groove. This improves the stability of the docking sealing plate during operation.

[0006] According to the externally mounted leaf spring of this utility model, an elastic rope is fixedly connected to the upper surface of the leaf spring body, and the upper end of the elastic rope is fixedly connected to the surface of the weight tube. This improves the effect of the weight tube.

[0007] According to the externally mounted leaf spring of this utility model, the front surface of the mounting block is provided with a receiving groove, and when the leaf spring is installed, the front end of the winding rod is located inside the receiving groove. This improves the flatness of the mounting plate surface.

[0008] According to the externally mounted leaf spring of this utility model, the front end of the winding rod is fixedly connected to a socket rod, and when installing the leaf spring, the socket rod engages with the mounting block. This improves the stability of the winding rod.

[0009] Beneficial effects:

[0010] Compared with existing technologies, this externally mounted leaf spring uses a mounting block, a connecting plate, a slot, a wear-resistant rope, and a winding rod to seal the opening of the eyelet through a snap-fit ​​method, which improves the stability of the leaf spring after suspension. In addition, the wear-resistant rope makes it easy to apply external force to the connecting plate, thus improving the convenience of removing the hanging leaf spring. Attached Figure Description

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Referring to Figures 1-4, the embodiment of this utility model, a leaf spring with externally mounted coiled ears, includes: a leaf spring body 1, with arc-shaped coiled ears 2 respectively provided on the left and right sides of the leaf spring body 1; a mounting block 3 is fixedly connected to the surface of the leaf spring body 1; and two mating sealing plates 4 are slidably connected to the surface of the leaf spring body 1, located on the left and right sides of the mounting block 3. The side of the mating sealing plate 4 away from the mounting block 3 engages with the arc-shaped coiled ears 2. The mating sealing plates 4 are used to close the opening of the arc-shaped coiled ears 2, forming a fully enclosed suspension structure, which improves the stability of the leaf spring after suspension. The surface of the arc-shaped coiled ears 2 opposite to the mating sealing plates 4 is provided with a magnetic locking block 10 and a magnetic slot 11 respectively. When the leaf spring is installed, the magnetic locking block 10 is located inside the magnetic slot 11, and the magnetic slot 11 cooperates with the magnetic locking block 10 to increase the stability when the mating sealing plates 4 are in action.

[0020] Specifically, after the leaf spring is hung in the designated position, the docking sealing plate 4 is pushed close to the arc-shaped lug 2. After the docking sealing plate 4 is close to the arc-shaped lug 2, the magnetic attraction further assists the docking plate 4 and the arc-shaped lug 2 to engage. After the docking sealing plate 4 and the arc-shaped lug 2 engage, the docking sealing plate and the arc-shaped lug 2 wrap around the suspension point, thereby improving the stability of the leaf spring after suspension.

[0021] A spring 6 is fixedly connected between the mounting block 3 and the mating sealing plate 4. The spring 6 applies a thrust close to the arc-shaped lug 2 to the mating sealing plate 4. A winding rod 12 is rotatably connected to the surface of the mounting block 3. A receiving groove 13 is provided on the front surface of the mounting block 3. When installing the leaf spring, the front end of the winding rod 12 is located inside the receiving groove 13. The front end of the winding rod 12 is fixedly connected to the socket rod 14. When installing the leaf spring, the socket rod 14 engages with the mounting block 3. A groove 5 is provided on the upper surface of the mounting block 3. The winding rod 12 passes through the groove 5. A wear-resistant rope 7 is fixedly connected to one end of the sealing plate 4 near the mounting block 3. The wear-resistant rope 7 cooperates with the winding rod 12 to limit the range of motion of the spring 6. The end of the wear-resistant rope 7 away from the sealing plate 4 is wrapped around the surface of the winding rod 12. A weight tube 8 is provided on the surface of the wear-resistant rope 7 near the mounting block 3 and the sealing plate 4. An elastic rope 9 is fixedly connected to the upper surface of the leaf spring body 1. The upper end of the elastic rope 9 is fixedly connected to the surface of the weight tube 8. The elastic rope 9 and the weight tube 8 cooperate to limit the range of motion of the wear-resistant rope 7 after breakage.

[0022] Specifically, before installing the leaf spring, first pull the winding rod 12 out of the storage groove 13, then rotate the winding rod 12 to wind the wear-resistant rope 7. Since the length of the wear-resistant rope 7 is fixed, during the winding process, the connecting sealing plate 4 gradually approaches the mounting block 3 while the spring 6 is compressed. After winding, push the winding rod 12 into the storage groove 13 and use the socket rod 14 to restrict the rotation of the winding rod 12. Then hang the leaf spring in the designated position and cut the wear-resistant rope 7. At this time, the spring 6 lacks external force to restrict its extension and restores itself, thereby driving the connecting sealing plate 4 to approach the arc-shaped coil ear 2 until the magnetic card block 10 enters the magnetic card slot 11. At the moment the taut wear-resistant rope 7 is cut, the elastic rope 9, which is in a stretched and taut state, contracts and, together with the gravity of the weight tube 8, restricts the range of motion of the wear-resistant rope 7.

[0023] Working principle: Before installing the leaf spring, the spring 6 is first compressed using the winding rod 12. After the leaf spring is installed, the deformation stress of the spring 6 is used to bring the mating sealing plate 4 close to the arc-shaped lug 2 and engage with it by cutting the wear-resistant rope 7. During this process, the wear-resistant rope 7 is a consumable item. When the leaf spring needs to be removed, the wear-resistant rope 7 connected to the mating sealing plate 4 needs to be found. By pulling the wear-resistant rope 7 outward, a force is applied to the mating sealing plate 4 to separate it from the arc-shaped lug 2. After the restraint of the mating sealing plate 4 is removed, the leaf spring can be removed. After the leaf spring is removed, the cut wear-resistant rope 7 needs to be manually reconnected, and the wear-resistant rope 7 can be reused repeatedly.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
