However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0033] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0034] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0035] In the present application, unless otherwise clearly specified and limited, if there are terms such as "install", "connect", "couple", "fix", etc., these terms should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0036] In the present application, unless otherwise clearly specified and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

If present, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0038] A suspension system is a structure that connects the vehicle wheels to the frame or body, responsible for absorbing the impact from the road surface, maintaining the contact between the wheels and the ground, thereby improving the vehicle's handling and comfort. The main function of the suspension is to cushion the unevenness of the road surface and reduce the vibration received by the vehicle during driving. The suspension system consists of multiple moving parts, including elastic elements such as coil springs or leaf springs, shock absorbers, links, control arms, etc. In a suspension system using leaf springs, one end of the leaf spring is fixed to the longitudinal beam of the frame, while the other end is connected to the wheel or axle. When the vehicle is driving, the leaf spring bears the weight from the upper part of the vehicle through the longitudinal beam, and at the same time absorbs the road surface impact force and transmits it back to the overall structure of the vehicle through the longitudinal beam.

[0039] Among them, the longitudinal beam of the frame is the main load-bearing structure of the frame, usually distributed along the length direction of the vehicle, and is the "skeleton" of the vehicle. The longitudinal beam is responsible for bearing the main weight of the vehicle, including the weight of the body, engine, cargo, and passengers, and transmitting these loads to the wheels through the suspension.

[0040] The following will further elaborate on the embodiments of the present application in conjunction with the attached Figure 1 and Figure 2 drawings.

[0041] Figure 1 FIG. shows the structural schematic diagram of the leaf spring assembly auxiliary device in an embodiment of the present application. Figure 2 FIG. shows the cooperation schematic diagram of the leaf spring assembly auxiliary device and the leaf spring 5 in an embodiment of the present application. Refer to Figure 1 and Figure 2 FIGS., the leaf spring assembly auxiliary device provided in an embodiment of the present application includes a fixed seat 1; a telescopic assembly, which is disposed through the fixed seat 1 and is used to cooperate with the fixed seat 1 and abut against the longitudinal beam 4 of the frame to position the fixed seat 1; a clamping member 3, which is connected to the telescopic assembly and is used to clamp the leaf spring 5.

[0042] Among them, the telescopic component is adjustably arranged in the fixed seat 1. During the process of assembling the leaf spring 5 to the vehicle frame longitudinal beam 4, the telescopic component is adjusted until the fixed seat 1 cooperates with the telescopic component and abuts against the vehicle frame longitudinal beam 4 from both sides of the vehicle frame longitudinal beam 4, and the fixed seat 1 is fixed to the vehicle frame longitudinal beam 4. It can be understood that the position of the telescopic component passing through the fixed seat 1 and the clamping member 3 connected to the telescopic component relative to the vehicle frame longitudinal beam 4 is also determined. By adjusting the clamping state of the clamping member 3 to clamp the leaf spring 5, it is convenient for the assembler to assemble the leaf spring 5 to the vehicle frame longitudinal beam 4.

[0043] The above-mentioned leaf spring assembly auxiliary device includes: a fixed seat 1; a telescopic component passing through the fixed seat 1 and used for cooperating with the fixed seat 1 and abutting against the vehicle frame longitudinal beam 4 to position the fixed seat 1; a clamping member 3 connected to the telescopic component and used for clamping the leaf spring 5. In this embodiment, the positioning and assembly of the leaf spring 5 can be realized by the cooperation of the telescopic component and the fixed seat 1. By adjusting the clamping state of the clamping member 3 and the telescopic state of the telescopic component, the device can be disassembled conveniently and quickly, which can reduce the structural complexity of the leaf spring assembly auxiliary device and the complexity of the leaf spring 5 assembly process, and effectively improve the positioning accuracy and stability of the leaf spring 5, and avoid the displacement of the leaf spring 5 during the assembly process, resulting in an impact on the subsequent assembly process.

[0044] Continue to refer to Figure 1 , in a leaf spring assembly auxiliary device provided in an embodiment of the present application, the fixed seat 1 includes: a transverse support shaft 11; a first longitudinal support shaft 12 and a second longitudinal support shaft 13 arranged in parallel and respectively connected to the first end and the second end of the transverse support shaft 11; a reinforcing plate 14 respectively connected to the first longitudinal support shaft 12 and the second longitudinal support shaft 13.

[0045] Among them, the distance between the inner sides of the first longitudinal support shaft 12 and the second longitudinal support shaft 13 depends on the width of the vehicle frame wing surface, and an appropriate increase of 5-10 mm is made on this basis. In the application scenario of assembling the leaf spring 5 to the vehicle frame longitudinal beam 4, the distance between the inner sides of the first longitudinal support shaft 12 and the second longitudinal support shaft 13 is slightly larger than the thickness of the vehicle frame longitudinal beam 4.

[0046] Preferably, the reinforcing plate 14 is perpendicular to the first longitudinal support shaft 12 and the second longitudinal support shaft 13 respectively, that is, the reinforcing plate 14 is arranged in parallel with the transverse support shaft 11.

[0047] In a possible implementation manner, the telescopic component includes: a first telescopic member 21 passing through the first longitudinal support shaft 12 and the longitudinal support shaft and connected to the clamping member 3. In a possible implementation manner, the telescopic component further includes: a second telescopic member 22 passing through the second longitudinal support shaft 13 and used for abutting against the vehicle frame longitudinal beam 4.

[0048] In a possible implementation, first through holes of the same height are provided on the first longitudinal support shaft 12 and the second longitudinal support shaft 13 for the telescopic assembly to pass through. Specifically, in Figure 1 from the perspective of Figure 1 , the left longitudinal support shaft is the first longitudinal support shaft 12, and the right longitudinal support shaft is the second longitudinal support shaft 13. The first telescopic member 21 is inserted into the first through holes provided on the first longitudinal support shaft 12 and the second longitudinal support shaft 13, and the clamping member 3 is connected to the left end of the first telescopic member 21. Among them, the first through holes provided on the first longitudinal support shaft 12 and the second longitudinal support shaft 13 are arranged horizontally to limit the moving direction of the first telescopic member 21, that is, the first telescopic member 21 inserted into the first through holes can move horizontally under the limitation of the first through holes.

After the first telescopic member 21 is adjusted to a suitable position, it can be locked to prevent displacement. It can be understood that a locking structure is also provided between the second telescopic member 22 and the fixed seat 1. Optionally, the locking structure can be a threaded fastener. When the threaded fastener is in a relaxed state, the first telescopic member 21 can move horizontally. After the first telescopic member 21 is adjusted to a suitable position, the first telescopic member 21 is locked by rotating the threaded fastener, so as to fix the first telescopic member 21. Optionally, the locking structure can also be a structure locked by using a spring buckle, a wedge-shaped clamping block or a friction gasket. The locking structure between the first telescopic member 21 and the fixed seat 1 can be arranged around the first longitudinal support shaft 12; the locking structure between the second telescopic member 22 and the fixed seat 1 can be arranged around the second longitudinal support shaft 13. The two locking structures can be the same or different.

[0051] In a possible implementation, scale lines or a digital display device are provided on the first telescopic member 21. Optionally, the scale lines or the digital display device on the rod of the first telescopic member 21 can be provided only on the side away from the clamping member 3 for the assembly personnel to determine the adjustment position of the first telescopic member 21 in real time.

[0052] In a possible implementation, an anti-collision cushion block is provided on the outer surface of one side of the second telescopic member 22 close to the longitudinal beam 4 of the vehicle frame. Optionally, the anti-collision cushion block can be a nylon cushion block or a rubber cushion block. The anti-collision cushion block in this implementation has a certain elasticity, can absorb mechanical vibrations, play a role in shock absorption and anti-collision, and has good wear resistance, which can protect the second telescopic member 22 and the vehicle frame, avoid surface wear of the second telescopic member 22 and the vehicle frame due to long-term contact or movement, and thus extend the service life of the equipment.

[0053] In a possible implementation, the fixed seat 1 further includes a handle 15, which is arranged at the top of the transverse support shaft 11 for the assembly personnel to hold, so as to improve the convenience of using the leaf spring assembly auxiliary device.

[0054] Optionally, the first longitudinal support shaft 12, the second longitudinal support shaft 13, the transverse support shaft 11, the reinforcing plate 14 and the handle 15 that make up the fixed seat 1 can be fixedly connected together by welding or integrally formed.

[0055] During the assembly process of the leaf spring 5, the first longitudinal support shaft 12 and the second longitudinal support shaft 13 of the fixed seat 1 are respectively arranged on both sides of the longitudinal beam 4 of the vehicle frame, the reinforcing plate 14 is located at the top of the longitudinal beam 4 of the vehicle frame, the inner side of the first longitudinal support shaft 12 contacts the first side of the longitudinal beam 4 of the vehicle frame, the second longitudinal support shaft 13 and the second telescopic member 22 are arranged on the second side of the longitudinal beam 4 of the vehicle frame, the second telescopic member 22 is adjusted until the second telescopic member 22 abuts against the second side of the longitudinal beam 4 of the vehicle frame, and the inner side of the first longitudinal support shaft 12 abuts against the first side of the longitudinal beam 4 of the vehicle frame, so that the fixed seat 1 is fixed relative to the longitudinal beam 4 of the vehicle frame.

[0056] In this embodiment, through the cooperation between the first longitudinal support shaft 12, the second longitudinal support shaft 13 and the second telescopic member 22, the positioning of the fixed seat 1 and the leaf spring 5 can be realized on vehicle frames of different models, thereby expanding the application range of the leaf spring assembly auxiliary device.

[0057] Continue to refer to Figure 1 , the clamping member 3 in the leaf spring assembly auxiliary device provided in an embodiment of the present application includes: a top plate 31; a first clamping plate 32 and a second clamping plate 33 arranged in parallel, and the first clamping plate 32 and the second clamping plate 33 are adjustably connected to the top plate 31.

[0058] Wherein, the extending directions of the first clamping plate 32 and the second clamping plate 33 are perpendicular to the central axis of the first telescopic member 21, and a locking structure is provided between the first clamping plate 32 and / or the second clamping plate 33 and the top plate 31. After the distance between the first clamping plate 32 and the second clamping plate 33 is adjusted to a suitable position, it can be locked to prevent displacement.

[0059] In a possible implementation, a waist-shaped hole is provided on the top plate 31. The first clamping plate 32 and the second clamping plate 33 are respectively connected to the waist-shaped hole on the top plate 31 through bolts, and the distance between the first clamping plate 32 and the second clamping plate 33 is adjusted by adjusting the connection position.

[0060] In a possible implementation, the first clamping plate 32 and the second clamping plate 33 are respectively connected to the output ends of the cylinders. The cylinders are used to drive the first clamping plate 32 and the second clamping plate 33, so as to adjust the distance between the first clamping plate 32 and the second clamping plate 33.

[0061] In a possible implementation, in Figure 1 From the perspective of, the clamping plate on the left is the first clamping plate 32, and the clamping plate on the right is the second clamping plate 33. The second clamping plate 33 is fixedly connected to the top plate 31 and is also fixedly connected to the end of the first telescopic member 21. The first clamping plate 32 is adjustably connected to the top plate 31, and the distance between the first clamping plate 32 and the second clamping plate 33 is adjusted by adjusting the first clamping plate 32. Optionally, the second clamping plate 33 and the end of the first telescopic member 21 are fixedly connected by welding, so as to ensure the connection strength between the clamping member 3 and the first telescopic member 21.

[0062] In this embodiment, by using the adjustable clamping member 3 to clamp the leaf spring 5, the leaf spring 5 can be positioned, locked and disassembled conveniently and quickly, and it can adapt to leaf springs 5 of different sizes, reducing the operation complexity during the positioning process of the leaf spring 5.

[0063] In an embodiment of the present application, a leaf spring assembly auxiliary device is provided, which is applied to the general assembly link of a commercial vehicle with a double rear axle equipped with a leaf spring 5. Before assembly, the leaf spring 5 needs to be installed on the large bracket on the frame longitudinal beam 4, so that the leaf spring 5 is parallel to the frame longitudinal beam 4 and the distance meets the requirements of the assembled leaf spring spacing. In Figure 2 From the perspective of, Figure 2 The figure shows the use state of the leaf spring assembly auxiliary device placed at the rear position of the leaf spring 5.

[0064] The leaf spring assembly auxiliary device provided in this embodiment includes:

[0065] A fixed seat 1, including: a transverse support shaft 11; a first longitudinal support shaft 12 and a second longitudinal support shaft 13 arranged in parallel, which are respectively connected to the first end and the second end of the transverse support shaft 11; a reinforcing plate 14, which is respectively connected to the first longitudinal support shaft 12 and the second longitudinal support shaft 13. The first longitudinal support shaft 12 and the second longitudinal support shaft 13 are provided with first through holes at the same height for the telescopic assembly to pass through; a handle 15 is arranged on the top of the transverse support shaft 11.

[0066] The telescopic assembly is inserted through the fixed seat 1 and is used to cooperate with the fixed seat 1 and abut against the longitudinal beam 4 of the vehicle frame to position the fixed seat 1. The telescopic assembly includes: a first telescopic member 21 inserted through the first longitudinal support shaft 12 and the longitudinal support shaft and connected to the clamping member 3; a second telescopic member 22 inserted through the second longitudinal support shaft 13 and used to abut against the longitudinal beam 4 of the vehicle frame. A scale line or a digital display device is provided on the first telescopic member 21, and an anti-collision cushion block is provided on the outer surface of the side of the second telescopic member 22 close to the longitudinal beam 4 of the vehicle frame.

[0067] The clamping member 3 is connected to the telescopic assembly and is used to clamp the leaf spring 5. The clamping member 3 includes: a top plate 31; a first clamping plate 32 and a second clamping plate 33 arranged in parallel, and the first clamping plate 32 and the second clamping plate 33 are adjustably connected to the top plate 31.

[0068] Before assembling the leaf spring 5, place the fixed seat 1 on the longitudinal beam 4 of the vehicle frame and adjust the second telescopic member 22 to fix the fixed seat 1 relative to the longitudinal beam 4 of the vehicle frame. If it does not fit tightly, the fixed seat 1 can be appropriately lifted to slightly separate the reinforcing plate 14 from the upper wing surface of the longitudinal beam 4 of the vehicle frame to eliminate the situation where the inner side of the first longitudinal support shaft 12 cannot fit with the longitudinal beam 4 of the vehicle frame due to the non-perpendicularity between the upper wing surface and the side surface of the longitudinal beam 4 of the vehicle frame. This step is based on the side surface of the longitudinal beam 4 of the vehicle frame to fix the fixed seat 1 to the longitudinal beam 4 of the vehicle frame.

[0069] According to the specific leaf spring distance requirements, move the first telescopic member 21 and adjust the extended length of the first telescopic member 21. The extended length varies according to the assembly requirements of different vehicle models. The distance from the inner surface of the second clamping plate 33 to the side surface of the vehicle frame is calculated based on the distance between the leaf springs on both sides, the width of the vehicle frame, the width of the leaf spring, and the thickness of the auxiliary device for assembling the leaf spring. The moving position of the first telescopic member 21 is determined in real time through the scale line or the digital display device provided on the first telescopic member 21, avoiding conversion and measurement during each assembly and improving efficiency.

[0070] With the clamping member 3 in the relaxed state, move the to-be-assembled leaf spring 5 into the opening of the clamping member 3, adjust the first clamping plate 32 and / or the second clamping plate 33, and contract until it clamps the leaf spring 5. The first clamping plate 32 and the second clamping plate 33 are arranged in parallel to ensure the distance and parallel relationship of the leaf spring 5 relative to the vehicle frame.

[0071] After clamping the leaf spring 5, the leaf spring 5 can be tightened. After the leaf spring 5 is tightened, loosen the clamping member 3 and the telescopic assembly, and withdraw the auxiliary device for assembling the leaf spring to complete the assembly of the leaf spring 5.

[0072] In an embodiment of the present application, an auxiliary system for assembling the leaf spring 5 is provided, including: at least one set of the auxiliary device for assembling the leaf spring in the above embodiment.

[0073] Preferably, during the assembly of the leaf spring 5, two sets of the leaf spring assembly auxiliary devices in the above embodiments are used and are respectively arranged at both ends of the leaf spring 5. If only one set of the leaf spring assembly auxiliary device is used, it is arranged at the middle position of the leaf spring 5. Optionally, in the case of using one set of the leaf spring assembly auxiliary device, the contact area between the first clamping plate 32 and the second clamping plate 33 in the clamping member 3 is enlarged to improve the clamping stability. Optionally, the clamping stability can be improved by increasing the longitudinal width of the first clamping plate 32 and the second clamping plate 33.

For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
