[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A limiting mechanism for an automobile leaf spring comprises: a leaf spring body and a fixed base plate, wherein the fixed base plate is movably mounted on the bottom of the leaf spring body, a limiting block is fixedly mounted on the top of the fixed base plate, a first pad is fixedly mounted on the top of the limiting block, a second pad is movably mounted on the top of the leaf spring body, and a buffer block is fixedly mounted on the top of the second pad.

[0007] As a preferred solution of the utility model, limiting grooves are provided on both sides of the top of the buffer block, anti-skid pads are arranged inside the limiting grooves, and U-shaped bolts are movably installed on the top of the anti-skid pads.

[0008] As a preferred solution of the utility model, the number of the U-shaped bolts is 2, and the two U-shaped bolts are symmetrically arranged.

[0009] As a preferred solution of the utility model, the U-shaped bolt is connected to the fixed base plate through a first fastening nut, and first mounting holes are provided at four corners of the top of the fixed base plate.

[0010] As a preferred solution of the utility model, a second mounting hole is opened in the middle portion of the top of the fixed base plate.

[0011] As a preferred solution of the utility model, a connecting sleeve is provided at the middle portion of the top of the buffer block.

[0012] As a preferred solution of the utility model, a central bolt penetrating to the bottom of the second mounting hole is movably installed in the inner cavity of the connecting sleeve, and second fastening nuts are respectively threadedly connected at both ends of the central bolt.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] This solution can effectively reduce the direct friction between the leaf spring body and the limit block and the buffer block by arranging the first pad and the second pad on the top of the limit block and the top of the leaf spring body, thereby achieving the purpose of extending the service life of the limit mechanism. When the wear reaches a certain amount, the first pad and the second pad can be replaced without replacing the entire limit mechanism, which can effectively improve the wear resistance of the product. Since the limit mechanism is affected by vibration, it may shift over time. The first pad and the second pad can also prevent this from happening, making the automobile chassis highly stable, greatly enhancing the use effect and stability of the limit mechanism, and reducing failures and maintenance costs.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] like Figures 1 to 4 As shown, the utility model provides a limiting mechanism for an automobile leaf spring, comprising: a leaf spring body 1 and a fixed base plate 2, the fixed base plate 2 is movably mounted at the bottom of the leaf spring body 1, a limiting block 3 is fixedly mounted on the top of the fixed base plate 2, a first pad 4 is fixedly mounted on the top of the limiting block 3, a second pad 5 is movably mounted on the top of the leaf spring body 1, and a buffer block 6 is fixedly mounted on the top of the second pad 5.

[0024] refer to Figure 2 , Figure 3 and Figure 4 Limiting grooves 7 are provided on both sides of the top of the buffer block 6, and anti-slip pads 8 are provided inside the limiting grooves 7. U-bolts 9 are movably installed on the top of the anti-slip pads 8. Two U-bolts 9 are provided, and the two U-bolts 9 are symmetrically arranged. The U-bolts 9 are connected to the fixed base plate 2 through first fastening nuts 10, and first mounting holes 11 are provided at the four corners of the top of the fixed base plate 2.

[0025] By adopting the above scheme: through the setting of the first mounting hole 11, two U-shaped bolts 9 can be passed through the first mounting hole 11 and fixed in the limiting groove 7 on the top of the buffer block 6, and the anti-slip pad 8 in the limiting groove 7 can increase the friction force of the U-shaped bolt 9, further ensuring the stability between the U-shaped bolt 9 and the buffer block 6, the leaf spring body 1 and the fixed base plate 2.

[0026] refer to Figure 2 , Figure 3 and Figure 4 A second mounting hole 12 is provided in the middle part of the top of the fixed base plate 2, and a connecting sleeve 13 is provided in the middle part of the top of the buffer block 6. A central bolt 14 penetrating to the bottom of the second mounting hole 12 is movably installed in the inner cavity of the connecting sleeve 13, and second fastening nuts 15 are respectively threadedly connected at both ends of the central bolt 14.

[0027] The above solution is adopted: by setting the central bolt 14 to fix the main plate and the auxiliary plate in the leaf spring body 1, the misalignment thereof can be prevented.

[0028] Working principle: When in use, the first pad 4 and the second pad 5 on both sides of the leaf spring body 1 are subjected to direct friction between the leaf spring body 1 and the limit block 3 and the buffer block 6 when the vehicle is running, so as to avoid direct damage to the limit block 3 and the buffer block 6. When the wear of the first pad 4 and the second pad 5 reaches a certain amount, the U-bolt 9 and the center bolt 14 can be removed, and the first pad 4 and the second pad 5 can be replaced without replacing the entire limit mechanism, thereby effectively improving the wear resistance of the product, thereby effectively improving the service life of the limit mechanism and reducing maintenance costs.
