Description

Technical Field

[0001] This utility model relates to the field of leaf spring clamp technology, and in particular to a composite clamp for automotive leaf springs that does not require riveting. Background Technology

[0002] Leaf springs are the most widely used elastic element in automotive suspensions. They are elastic beams of approximately equal strength, composed of several alloy spring leaves of equal width but unequal length. The two ends of the leaf spring are fixed under the vehicle body. When the leaf spring is under force, it uses its own elasticity to buffer the pressure. Currently, leaf springs in domestic commercial vehicles mostly use clamps as limiting devices to prevent the leaves from moving laterally.

[0003] Existing composite clamps for leaf springs require rivet connections during use. However, rivet connections involve numerous parts, and the loss of any part can affect assembly and installation. This prevents the integrated and rapid clamping of leaf springs, reducing operational efficiency during production. Utility Model Content

[0004] The purpose of this utility model is to provide a riveting-free composite clamp for automotive leaf springs. The threaded rod and threaded hole achieve threaded fastening, and the upper and lower clamping bodies are matched to achieve an integrated structure, which firmly clamps the leaf spring. At the same time, the limiting plate limits the connecting lugs, which increases the firmness and makes it less likely to come off.

[0005] To achieve the above objectives, a riveting-free composite clamp for automotive leaf springs is provided, comprising: an upper clamp body and a lower clamp body, wherein one end of the upper clamp body and the lower clamp body are fixedly connected to a connecting lug, both ends of the upper clamp body are fixedly connected to protrusions on both sides of the bottom of the connecting lugs, and both ends of the lower clamp body are provided with grooves, wherein the protrusions and grooves are inserted into each other.

[0006] The groove is provided with a threaded rod, the bottom end of which is rotatably fitted with a limiting plate, and the limiting plate and the two ends of the lower clamp are fixedly connected.

[0007] According to the aforementioned riveting-free composite clamp for automotive leaf springs, one end of the threaded rod is fixedly connected to a knob.

[0008] According to the aforementioned composite clamp for automotive leaf springs that requires no riveting, a threaded hole is provided in the middle of the protrusion, and the threaded hole and the threaded rod are threadedly engaged.

[0009] According to the aforementioned composite clamp for automotive leaf springs that requires no riveting, both the connecting lugs and the protrusions are made of rigid materials.

[0010] Beneficial effects:

[0011] 1. This utility model is provided with an upper clamping body, a lower clamping body, connecting ears, and grooves. The two protrusions on both sides of the connecting ears at the bottom of the upper clamping body are inserted into the grooves on both sides of the connecting ears at the top of the lower clamping body. The insertion and engagement of the protrusions and grooves can keep the upper and lower clamping bodies vertically and horizontally fixed, and it is not easy for lateral displacement to occur. Through the insertion and fixing structure, the connection is stronger and more secure.

[0012] 2. This utility model is equipped with a threaded rod, a threaded hole, and a connecting lug. By rotating the knob, the threaded rod and threaded hole are threadedly fastened, and the upper and lower clamping bodies cooperate to achieve an integrated connection structure, which firmly clamps the steel leaf spring. At the same time, the limiting plate limits the connecting lug, increasing the firmness and making it less likely to detach. It achieves an integrated and convenient connection. The complexity of fixing without using riveting methods can be eliminated by manually rotating the knob.

[0021] 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.

[0022] Reference Figure 1-4 This utility model discloses a riveting-free composite clamp for automotive leaf springs, comprising an upper clamp body 1 and a lower clamp body 5. Each end of the upper clamp body 1 and the lower clamp body 5 is fixedly connected to a connecting lug 2. The upper clamp body 1 is fitted onto the top of the leaf spring, and then the lower clamp body 5 is fitted onto the bottom of the leaf spring. The two protrusions 3 on both sides of the connecting lug 2 at the bottom of the upper clamp body 1 are then inserted into the two grooves 4 on both sides of the connecting lug 2 at the top of the lower clamp body 5. Both the connecting lug 2 and the protrusions 3 are made of rigid material, which provides strong resistance. With enhanced strength and stability, both ends of the upper clamping body 1 are fixedly connected to the bottom sides of the connecting ears 2, and both ends of the lower clamping body 5 are provided with grooves 4. The insertion and engagement of the protrusions 3 and grooves 4 can keep the upper clamping body 1 and the lower clamping body 5 vertically and horizontally fixed, and it is not easy for lateral displacement to occur. The protrusions 3 and grooves 4 are inserted and engaged, and a threaded hole 9 is provided in the middle of the protrusion 3. The threaded connection between the threaded hole 9 and the threaded rod 8 makes it less likely to loosen or fall off, and it is more practical. The threaded hole 9 and the threaded rod 8 are threadedly engaged.

[0023] The groove 4 has a threaded rod 8 inside. By rotating the knob 6, the threaded rod 8 and the threaded hole 9 are threaded together. The upper clamping body 1 and the lower clamping body 5 are engaged to achieve an integrated structure, which firmly clamps the leaf spring. The bottom end of the threaded rod 8 rotates and engages with the limiting plate 7. The limiting plate 7 limits the connecting ear 2, increasing the firmness and preventing it from easily dislodging. This achieves an integrated and convenient connection. The limiting plate 7 and the connecting ears 2 at both ends of the lower clamping body 5 are fixedly connected. One end of the threaded rod 8 is fixedly connected to the knob 6, which is easy to operate. At the same time, a cross groove is opened inside the knob 6 to facilitate the use of tools to tighten it.

[0024] Working principle: In use, the upper clamp 1 is first placed on the top of the leaf spring, and then the lower clamp 5 is placed on the bottom of the leaf spring. The two protrusions 3 on both sides of the bottom connecting ear 2 of the upper clamp 1 are then inserted into the two grooves 4 on both sides of the top connecting ear 2 of the lower clamp 5. This insertion fit between the protrusions 3 and the grooves 4 keeps the upper clamp 1 and the lower clamp 5 vertically and horizontally fixed, preventing lateral displacement. Then, by rotating the knob 6, the threaded rod 8 and the threaded hole 9 are tightened, and the upper clamp 1 and the lower clamp 5 are connected in an integrated structure, which firmly clamps the leaf spring. At the same time, the limiting plate 7 limits the connecting ear 2, increasing the firmness and preventing it from falling off, thus achieving a convenient integrated connection.
