Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile suspension, in particular to a suspension structure and an automobile. BACKGROUND

[0002] The suspension structure is one of the important components of a vehicle. The function of the steel plate spring is to connect the vehicle frame and the vehicle axle together in a suspended form. The steel plate spring is between the vehicle frame and the vehicle axle, bears the load impact of the wheels on the vehicle frame, reduces the violent vibration of the vehicle body, and maintains the stability of the vehicle in driving and the adaptability to different road conditions. During the assembly process of the steel plate spring suspension, some parts are prone to errors due to assembly errors, such as an excessively large wheelbase between the vehicle axles or an excessively large wheelbase on the left and right sides of the vehicle.

[0003] Because the suspension structure itself has a large volume and a complex internal structure, it increases the difficulty of improving the positional relationship between the vehicle axle and the vehicle frame by using the suspension structure. SUMMARY

[0039] The suspension structure 100 is an important assembly of the automobile, which is used to elastically connect the vehicle frame 300 and the vehicle wheel together. The suspension structure 100 can be roughly divided into two categories: independent suspension structure 100 and non-independent suspension structure 100. For example, the leaf spring suspension is a kind of non-independent suspension structure 100. It uses the leaf spring as the elastic element of the non-independent suspension, which can simplify the suspension structure 100.

[0040] When the leaf spring suspension and other suspension structures 100 are assembled on the automobile body, the following problems can easily occur between the automobile leaf spring suspension axle 200 (front axle 200a or rear axle 200b) and the vehicle frame 300 due to assembly errors.

[0041] For example, when the front axle 200a and the rear axle 200b are both assembled on the vehicle frame 300, the front axle 200a and the rear axle 200b can be arranged non-perpendicularly relative to the vehicle frame 300, that is, the included angle between at least one of the front axle 200a and the rear axle 200b and the vehicle frame 300 is an acute angle or an obtuse angle. Alternatively, the distance between the front axle 200a and the rear axle 200b along the extension direction of the vehicle frame 300 is not equal to the preset distance, and the like.

[0042] Any of the above situations needs to adjust at least one of the front axle 200a and the rear axle 200b. In order to facilitate the adjustment of the position of the axle 200 assembled on the vehicle frame 300, some embodiments of the present application provide a suspension structure 100.

[0043] Please refer to Figure 1 and Figure 2The suspension structure 100 comprises a back plate 10, a mounting bracket 20 and an adjusting assembly 30. The back plate 10 is configured to be fixed to the vehicle frame 300. The mounting bracket 20 is configured to mount the axle 200 (e.g. the front axle 200a). The mounting bracket 20 has a first end 21 and a second end 22 oppositely arranged in the first direction X. The first end 21 is rotatably connected to the back plate 10. The adjusting assembly 30 is arranged at the second end 22 and is connected to the back plate 10. The adjusting assembly 30 is configured to adjust the relative position of the back plate 10 in the first direction X.

[0044] It is to be noted that the suspension structure 100 is arranged at each of the axles 200. For example, as shown in FIG. 1, when the vehicle comprises the front axle 200a and the rear axle 200b, the front axle 200a and the rear axle 200b are arranged in the first direction X and extend in the second direction Y. The second direction Y is perpendicular to the first direction X. When the front axle 200a and the rear axle 200b are in the normal assembly state, the front axle 200a and the rear axle 200b are perpendicular to the vehicle frame 300. The front axle 200a and the rear axle 200b are both provided with the suspension structure 100. Figure 1

[0045] The working principle of the suspension structure 100 will be described below by taking the problem of the assembly of the front axle 200a to the vehicle frame 300 as an example.

[0046] In some examples, it is assumed that the initial state of the assembly of the front axle 200a and the rear axle 200b to the vehicle frame 300 is that the angle between the front axle 200a and the vehicle frame 300 is an acute angle, the angle between the rear axle 200b and the vehicle frame 300 is a right angle, and the distance between the front axle 200a and the rear axle 200b is equal to the preset distance.

[0047] At this time, the adjusting assembly 30 can be operated to move the mounting bracket 20, so as to deflect the front axle 200a relative to the vehicle frame 300 through the mounting bracket 20, thereby increasing the angle between the front axle 200a and the vehicle frame 300. When the angle between the front axle 200a and the vehicle frame 300 is close to a right angle, the operation of the adjusting assembly 30 can be stopped. In this way, the front axle 200a is adjusted to be perpendicular to the vehicle frame 300.

[0048] Of course, when the angle between the front axle 200a and the vehicle frame 300 is an obtuse angle, the front axle 200a can be deflected in the opposite direction through the adjusting assembly 30, so as to decrease the angle between the front axle 200a and the vehicle frame 300, until the angle between the front axle 200a and the vehicle frame 300 is a right angle.

[0049] ​In some examples, the initial state of the front axle 200a and the rear axle 200b when assembled on the vehicle frame 300 is that the front axle 200a and the rear axle 200b are both vertically arranged relative to the vehicle frame 300, the rear axle 200b is installed at the preset position, and the distance between the front axle 200a and the rear axle 200b is greater than the preset distance.

[0050] At this time, the mounting bracket 20 can be moved towards the rear axle 200b by adjusting the adjusting assembly 30, so that the front axle 200a is moved towards the rear axle 200b as a whole by the mounting bracket 20, so as to shorten the distance between the front axle 200a and the rear axle 200b. When the front axle 200a reaches the preset position, the adjusting assembly 30 can be stopped, and the distance between the front axle 200a and the rear axle 200b is substantially equal to the preset distance. In this way, the front axle 200a is adjusted to the preset position.

[0051] It can be understood that when the front axle 200a and the rear axle 200b are both vertically arranged relative to the vehicle frame 300, the rear axle 200b is installed at the preset position, and the distance between the front axle 200a and the rear axle 200b is less than the preset distance, the front axle 200a can be moved away from the rear axle 200b as a whole by the adjusting assembly 30 until the distance between the front axle 200a and the rear axle 200b is equal to the preset distance, and then the adjusting assembly 30 is stopped.

[0052] In some other examples, the initial state of the front axle 200a and the rear axle 200b when assembled on the vehicle frame 300 is that the rear axle 200b is at the preset position and is vertically arranged relative to the vehicle frame 300, and the front axle 200a is not at the preset position, the distance between the front axle 200a and the rear axle 200b is greater than the preset distance, and the included angle between the front axle 200a and the vehicle frame 300 is an acute angle.

[0053] For the above case, the mounting bracket 20 can be first moved by the adjusting assembly 30, so that the front axle 200a is deflected relative to the vehicle frame 300, and when the included angle between the front axle 200a and the vehicle frame 300 is close to a right angle, the adjusting assembly 30 can be temporarily stopped. Then, the mounting bracket 20 is moved by the adjusting assembly 30 at the front axle 200a, so that the front axle 200a is moved towards the rear axle 200b as a whole, and when the distance between the front axle 200a and the rear axle 200b is equal to the preset distance, the adjusting assembly 30 can be stopped. In this way, the front axle 200a is adjusted to the preset position and is vertically arranged relative to the vehicle frame 300.

[0054] It should be noted that when the rear axle 200b has a similar situation as the front axle 200a, the rear axle 200b can be deflected or moved by the adjusting assembly 30 at the rear axle 200b, so that the rear axle 200b is at the preset position and is vertically arranged relative to the vehicle frame 300.

[0055] In summary, when the front axle 200a, the rear axle 200b and the like are not perpendicular to the frame 300 at the initial assembly, or the distance between the front axle 200a and the rear axle 200b is not equal to the preset distance, the adjusting assembly 30 installed at each axle 200 can drive the axle 200 to move relative to the frame 300, so that the final state of the axle 200 assembled on the frame 300 is in the preset state.

[0056] In this way, the flexibility and convenience of the adjusting assembly 30 are improved, and each axle 200 can be adjusted individually in different situations. Moreover, when the vehicle is in the off-line state, each axle 200 can also be adjusted so that the axle 200 is assembled on the frame 300 in the preset state.

[0057] As shown in Figure 2 and Figure 3 In some embodiments, at least one first adapter 40 is configured on one of the back plate 10 and the adjusting assembly 30, and at least two second adapters 50 are configured on the other. For example, a buckle assembly can be used as the first adapter 40 and the second adapter 50.

[0058] Please refer to Figure 4 and Figure 5 The at least two second adapters 50 and the at least one first adapter 40 can be arranged in the first direction X. The adjusting assembly 30 has a plurality of adjusting positions relative to the back plate 10 in the first direction X, and when the back plate 10 is in any adjusting position, the at least one first adapter 40 is matched with the at least one second adapter 50.

[0059] For example, when the back plate 10 is assembled in the No. 1 adjusting position of the adjusting assembly 30, the X-1 first adapter 40 can be matched with the Y1 second adapter 50, or the X-2 first adapter 40 is matched with the Y2 second adapter 50 at the same time, and so on, which is not limited here.

[0060] In addition, when the back plate 10 is assembled in different adjusting positions of the adjusting assembly 30, the matched first adapter 40 and the second adapter 50 are also different. For example, when the back plate 10 is assembled in the No. 1 adjusting position of the adjusting assembly 30, the X-1 first adapter 40 can be matched with the Y1 second adapter 50. When the back plate 10 is assembled in the No. 2 adjusting position of the adjusting assembly 30, the X-1 first adapter 40 can be matched with the Y2 second adapter 50, or the X-3 first adapter 40 can be matched with the Y2 second adapter 50, and so on.

[0061] The above arrangement not only simplifies the connection between the adjustment assembly 30 and the back plate 10, but also enables the adjustment assembly 30 to be quickly assembled at any adjustment position of the back plate 10. Because the first and second matching portions 40 and 50 are different at different adjustment positions, when the adjustment assembly 30 is moved in the first direction X, the distance of a single movement of the adjustment assembly 30 relative to the back plate 10 is predictable, which facilitates the user to adjust other components associated with the adjustment assembly 30 according to the adjustment distance of the adjustment assembly 30.

[0062] For further reference Figure 4 and Figure 5 In some embodiments, the back plate 10 is provided with first hole positions, and the adjustment assembly 30 is provided with second hole positions. One of the first and second hole positions can form the first matching portion 40, and the other can form the second matching portion 50. The first and second hole positions can be connected by the fastener 60.

[0063] For example, as shown in Figure 3 a bolt and a nut can be used as the fastener 60. One end of the bolt can pass through a first hole position and a second hole position in sequence and be connected with the nut.

[0064] The structures of the first and second matching portions 40 and 50 are both set as through holes, which not only facilitates the production and processing of the first and second matching portions 40 and 50, but also facilitates the disassembly of the fastener 60 from the first and second matching portions 40 and 50. In addition, it can also improve the connection stability when the first and second matching portions 40 and 50 are assembled together.

[0065] In some embodiments, the first and second matching portions 40 and 50 are each provided with at least two. In the first direction X, the distance between adjacent two first hole positions is L1, and the distance between adjacent two second hole positions is L2, wherein L1>L2.

[0066] For example, as shown in Figure 4 the back plate 10 is provided with a plurality of first matching portions 40. As shown in Figure 5 the adjustment assembly 30 is provided with a plurality of second matching portions 50. The first matching portion 40 forms a first hole position, and the second matching portion 50 forms a second hole position. Assuming that when the axle 200 is initially assembled on the frame 300, the X0 first hole position of the back plate 10 and the 0 second hole position of the adjustment assembly 30 are connected together, at this time, the included angle formed between the front axle 200a and the frame 300 can be an acute angle.

[0067] The first hole positions are distributed on the side close to the rear axle 200b and on the side away from the rear axle 200b. The distance between two adjacent first hole positions is L1.

[0068] Similarly, the adjusting assembly 30 is provided with a plurality of second hole positions. The second hole positions are distributed on the side close to the rear axle 200b and on the side away from the rear axle 200b. The distance between two adjacent second hole positions is L2.

[0069] In different adjusting positions, if the same second hole position of the adjusting assembly 30 is matched with different first hole positions of the back plate 10, the moving distance of the adjusting assembly 30 relative to the back plate 10 in the first direction X is a multiple of L1. If different second hole positions of the adjusting assembly 30 are matched with the same first hole position of the back plate 10, the moving distance of the adjusting assembly 30 relative to the back plate 10 in the first direction X is a multiple of L2. Therefore, the above arrangement can improve the accuracy of the movement of the adjusting assembly 30 relative to the back plate 10.

[0070] In some embodiments, all the first engaging portions 40 can be arranged in pairs corresponding to all the second engaging portions 50. For each adjusting position, only one pair of the first engaging portion 40 and the second engaging portion 50 are matched, and the first engaging portion 40 and the second engaging portion 50 matched in each adjusting position are different from each other.

[0071] For example, as shown in FIG. 1, the back plate 10 can be provided with a plurality of first engaging portions 40, and the first engaging portions 40 form the first hole positions. The adjusting assembly 30 can be provided with a plurality of second engaging portions 50, and the second engaging portions 50 form the second hole positions. Figure 4 The first engaging portions 40 are distributed on the side close to the rear axle 200b and on the side away from the rear axle 200b. The second engaging portions 50 are distributed on the side close to the rear axle 200b and on the side away from the rear axle 200b.

[0072] If the first mating part 40 (X-1) and the second mating part 50 (Y-1) can be connected together, then the front axle 200a can move a certain distance relative to its initial position toward the rear axle 200b. Since the distance between two adjacent first mating parts 40 is L1, and the distance between two adjacent second mating parts 50 is L2, the actual distance the front axle 200a moves toward the rear axle 200b relative to the frame 300 is L1 - L2.

[0073] Similarly, when the first mating part 40 of X-2 and the second mating part 50 of 2 are connected, the front axle 200a can move 2 (L1-L2) relative to the frame 300 in the direction of the rear axle 200b, and so on.

[0074] Similarly, when the first mating part 40 (X-1) and the second mating part 50 (Y-1) are connected, the front axle 200a can move L1-L2 relative to the frame 300 in a direction away from the rear axle 200b. Likewise, when the first mating part 40 (X-2) and the second mating part 50 (Y-2) are connected, the front axle 200a can move 2 (L1-L2) relative to the frame 300 in a direction away from the rear axle 200b, and so on. The specific distance and direction of movement of the front axle 200a relative to the frame 300 can be determined based on the actual situation.

[0075] For example, in Figure 3 In the specific example shown, the backplate 10 may have 10 positions, that is, five first mating parts 40 are arranged at intervals on each side of the first mating part 40 of X0. Similarly, the adjustment assembly 30 may also have 10 positions. Taking the first mating part 40 of X0 as the origin, the movement distance of the adjustment assembly 30 relative to the backplate 10 is between -5(L1-L2) and 5(L1-L2). It can also be understood that the movement distance of the front axle 200a relative to the frame 300 in the first direction X is between -5(L1-L2) and 5(L1-L2).

[0076] Compared to setting the spacing between two adjacent first mating parts 40 and the spacing between two adjacent second mating parts 50 to be equal, the above setting improves the movement accuracy of the adjustment component 30 along the first direction X between two adjacent adjustment positions.

[0077] like Figure 4 As shown, in some embodiments, the back plate 10 may be provided with a first connecting portion 11. The adjustment assembly 30 is provided with a second connecting portion 31, and the connection position of the first connecting portion 11 and the second connecting portion 31 in the first direction X is variable. It can also be understood that when the adjustment assembly 30 is connected to the back plate 10 in different adjustment positions, that is, when the adjustment assembly 30 moves relative to the back plate 10, the first connecting portion 11 and the second connecting portion 31 are always in a connected state, but the connection points of the two are changed.

[0078] Exemplarily, when the adjusting assembly 30 is in the first adjusting position and connected with the backboard 10, the second connecting part 50 of the adjusting assembly 30 and the first connecting part 40 of the backboard 10 are connected together, and the second connecting part 31 of the adjusting assembly 30 and the first connecting part 11 of the backboard 10 are also connected together.

[0079] When it is needed to change the adjusting position of the adjusting assembly 30, the first connecting part 40 and the second connecting part 50 can be first separated, and then the first connecting part 11 and the second connecting part 31 can be adjusted. For example, a sliding groove and a sliding block can be used as the first connecting part 11 and the second connecting part 31. Therefore, during the adjustment of the adjusting assembly 30 from the first adjusting position to the second adjusting position, the first connecting part 11 and the second connecting part 31 can be always in the connected state.

[0080] Thus, during the assembly of the adjusting assembly 30 in different adjusting positions of the backboard 10, because the first connecting part 11 and the second connecting part 31 can always connect the adjusting part and the mounting part, the first connecting part 11 and the second connecting part 31 can preliminarily limit and guide the adjusting assembly 30. The user only needs to move the adjusting assembly 30 to the preset position, and then connect the first connecting part 40 and the second connecting part 50 together, thereby accelerating the switching speed of the adjusting assembly 30 between different adjusting positions.

[0081] In some embodiments, a buckle assembly can also be used as the first connecting part 11 and the second connecting part 31, which will not be listed one by one here, as long as the first connecting part 11 and the second connecting part 31 can move along the first direction X.

[0082] Specifically, please refer to Figure 5 In some embodiments, the backboard 10 can be provided with a first through hole as the first connecting part 11, and the adjusting assembly 30 can be provided with a second through hole as the second connecting part 31. One of the first through hole and the second through hole can extend along the first direction X and be in a strip shape. Exemplarily, in Figure 5 the second through hole can extend along the first direction X and be in a strip shape.

[0083] The first through hole can be connected with the second through hole through a locking part 70. The locking part 70 can be a bolt and a nut used in pairs. One end of the bolt can pass through the first through hole and one of the second through holes in sequence and be connected with the nut. When the adjusting assembly 30 is initially assembled with the backboard 10, the fastening part 60, the first connecting part 11 and the second connecting part 31 are tightly connected together.

[0084] When adjusting the position of the adjusting component 30, first remove the fastener 60 connecting the first and second holes from the first and second holes. Then, loosen the locking member 70, ensuring that the locking member 70, the first connecting part 11, and the second connecting part 31 remain connected. Next, drive the adjusting component 30, which in turn moves the locking member 70 along the second through hole to a preset position. Once the adjusting component 30 reaches the preset position, tighten the locking member 70 to fix the adjusting component 30 to the back plate 10. Afterward, the fastener 60 can be used to connect the first and second holes together.

[0085] The above configuration not only simplifies the structure of the first connecting part 11 and the second connecting part 31, making them easier to manufacture and process, but also improves the connection stability between the adjusting component 30 and the back plate 10.

[0086] It is understood that in some embodiments, the first through hole and the second through hole can be simultaneously configured as strip-shaped structures extending along the first direction X. Since their working principles are similar, they will not be described in detail here.

[0087] For further information, please refer to [link / reference]. Figure 5 Along the first direction X, the total length of movement of the adjusting component 30 relative to the back plate 10 is L3. The extension length of the strip-shaped first through hole and the second through hole along the first direction X can be equal to L3.

[0088] For example, in Figure 5 In the example shown, the second through hole has a strip-shaped structure. Both the adjustment assembly 30 and the back plate 10 have 10 positions. Because the distance between two adjacent positions is L1-L2, the total length of the adjustment assembly 30 that can move relative to the back plate 10 along the first direction X is 10(L1-L2). That is, L3 equals 10(L1-L2), and the length of the second connecting portion 31 is at least greater than 10(L1-L2).

[0089] This design minimizes the material used in the second through hole without affecting its function, thereby reducing the production cost of the second through hole.

[0090] Understandably, the length of the second through hole can be determined based on the total length that the adjusting component 30 can move. Of course, in some examples, the length of the second through hole can also be greater than L3, and no specific limitation is made here.

[0091] like Figure 6 As shown, in some embodiments, the back plate 10 further includes a third through hole 12. The third through hole 12 may be located on one side of the first mating portion 40 and extends along the first direction X in a strip shape. Figure 5 As shown, the adjustment component 30 is provided with a fourth through hole 32.Figure 3 As shown, the third through hole 12 and the fourth through hole 32 can be connected by the locking member 70. For example, a bolt and a nut are used as the locking member 70, so as to connect the third through hole 12 and the fourth through hole 32 together.

[0092] When the adjusting assembly 30 is initially assembled to the back plate 10, the locking member 70 can connect the third through hole 12 of the back plate 10 and the fourth through hole 32 of the adjusting assembly together. When it is needed to adjust the adjusting position of the adjusting assembly 30, the locking member 70 can be loosened, but the locking member 70, the third through hole 12 and the fourth through hole 32 are always connected. Then, the adjusting assembly 30 can be driven to move together with the locking member 70 along the third through hole 12 to a preset position. When the adjusting assembly 30 reaches the preset position, the locking member 70 can be tightened, so as to fix the adjusting assembly 30 to the back plate 10.

[0093] The above arrangement not only can guide the adjusting assembly 30 by the third through hole 12, so that the adjusting assembly 30 and the locking member 70 can quickly and accurately move to the preset position along the third through hole 12, but also can improve the connection stability between the adjusting assembly 30 and the back plate 10, so that the probability of the adjusting assembly 30 deflecting relative to the back plate 10 during the process of changing the adjusting position can be reduced, and the efficiency of the adjusting assembly 30 moving to the preset position during the process of changing the adjusting position can be further improved.

[0094] Further, as shown in some embodiments, Figure 6 The length of the third through hole 12 extending along the first direction X can be equal to L3.

[0095] For example, in the example shown, Figure 3 In the example shown, the adjusting assembly 30 and the back plate 10 can be provided with 10 gears, and because the interval between two adjacent gears is L1-L2, the total length of the adjusting assembly 30 moving relative to the back plate 10 along the first direction X is 10(L1-L2). That is, L3 is equal to 10(L1-L2), and the length of the third through hole 12 is at least greater than 10(L1-L2).

[0096] In this way, the material of the third through hole 12 can be reduced as much as possible without affecting the function of the third through hole 12, so that the production cost of the third through hole 12 can be reduced.

[0097] In addition, the suspension structure 100 is applied to a vehicle, and the vehicle can include a vehicle body and the suspension structure 100, and the suspension structure 100 is installed in the vehicle body. Because the vehicle includes the suspension structure 100, the vehicle has the functions and advantages of the suspension structure 100 provided by the above embodiments, which will not be described here.

[0098] Further, please refer toFigure 1 In some embodiments, the axle 200 is equipped with a suspension structure 100 arranged at intervals along the second direction Y. The second direction Y intersects the first direction X.

[0099] For example, in Figure 2 In the example shown, the first direction X and the second direction Y are perpendicular. Each axle 200 is fitted with a suspension structure 100 at both ends; that is, the front axle 200a is fitted with two suspension structures 100 spaced apart along the second direction Y, and the rear axle 200b is also fitted with two suspension structures 100 spaced apart along the second direction Y. Thus, the user can adjust the mounting position of the front axle 200a relative to the frame 300 via the two ends of the front axle 200a, and adjust the mounting position of the rear axle 200b relative to the frame 300 via the two ends of the rear axle 200b.

[0100] Because the axle 200 extends along the second direction Y, a suspension structure 100 is provided at each end of the axle 200, which can adjust the two ends of the axle 200 respectively, thereby adjusting the axle 200 more precisely so that the axle 200 can quickly deflect or move relative to the frame 300.

[0101] Of course, in some embodiments, each axle 200 may also be equipped with 3 suspension structures 100. This is not specifically limited here and can be determined according to the actual situation.

[0102] like Figure 1 As shown, in a specific example, a front axle 200a and a rear axle 200b are mounted on the frame 300, and a suspension structure 100 is mounted at both ends of the front axle 200a and the rear axle 200b.

[0103] The following is combined Figure 1 The example shown illustrates the working principle of the suspension structure 100.

[0104] like Figure 7 and Figure 8 As shown, the back plate 10 at the rear axle 200b can be fixedly connected to the frame 300, and the back plate 10 is also fixedly connected to a mounting plate 80. The mounting plate 80 and the back plate 10 can be connected by welding. In addition, the mounting plate 80 is provided with first holes spaced apart along the first direction X, and the distance between two adjacent first holes is L1.

[0105] Each mounting bracket 20 can be connected to one end of the front axle 200a via a U-bolt 90, wherein one end of each mounting bracket 20 is connected to the mounting plate 80 via an adjustment assembly 30, and the other end of each mounting bracket 20 can be hinged to the back plate 10.

[0106] It should be noted that in the present example, the adjusting assembly 30 can be an adjusting plate, and the adjusting plate can be provided with second hole positions which are spaced apart along the first direction X, and the spacing between two adjacent second hole positions is L2, and L1>L2. The second hole positions and the first hole positions are connected by bolts and nuts.

[0107] At different adjusting positions of the adjusting plate, different first hole positions and different second hole positions are connected, for example, at an initial adjusting position, the X0 first fitting part 40 is fitted with the Y0 second fitting part 50; at another adjusting position, the X1 first fitting part 40 is fitted with the Y1 second fitting part 50; at another adjusting position, the X-1 first fitting part 40 is fitted with the Y-1 second fitting part 50, and so on.

[0108] Secondly, the mounting plate 80 is further provided with a first connecting part 11 which can be located at one side of the first hole position close to the front axle 200a. The adjusting plate is provided with a second connecting part 31 which can extend along the first direction X and is in a strip shape, and is located at one side of the second hole position close to the front axle 200a. The adjusting plate is further provided with a plurality of fourth through holes 32, and the back plate 10 is provided with a plurality of third through holes 12. Each third through hole 12 extends along the first direction X and is in a strip shape.

[0109] Among them, the first connecting part 11 and the second connecting part 31 are connected by bolts, and the third through hole 12 and the fourth through hole 32 are also connected by bolts.

[0110] It should be noted that each suspension structure 100 assembled at the front axle 200a is similar to the suspension structure 100 at the rear axle 200b.

[0111] When the spacing between the front axle 200a and the rear axle 200b is not equal to the preset distance, but the front axle 200a and the rear axle 200b are both perpendicular to the vehicle frame 300, the suspension structure 100 at the corresponding position can be adjusted according to the actual situation, so as to drive the front axle 200a and / or the rear axle 200b to move as a whole.

[0112] When the spacing between the front axle 200a and the rear axle 200b is not equal to the preset distance, and at least one of the front axle 200a and the rear axle 200b is not perpendicular to the vehicle frame 300, that is, the spacing between the two ends of the front axle 200a and the rear axle 200b is not equal, that is, L3 is not equal to L4. According to the actual measured values of L3 and L4, the required adjusting axle 200 and the specific operation suspension structure 100 can be determined.

[0113] In Figure 8In the shown example, each of the front axle 200a and the rear axle 200b is provided with 10 adjustable gears, and when the front axle 200a is in the above-mentioned situation, the actual adjustment range of the suspension structure at the front axle 200a in the first direction X is between -5(L1-L2)L6 / L5~5(L1-L2)L6 / L5. When the rear axle 200b is in the above-mentioned situation, the actual adjustment range of the suspension structure at the rear axle 200b in the first direction X is between -5(L1-L2)L7 / L5~5(L1-L2)L7 / L5. In this way, the user can quickly and accurately adjust the front axle 200a and the rear axle 200b according to the actually measured data.

[0114] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but it should be considered that any combination of the technical features is within the scope of the present disclosure as long as the combination does not result in contradictions.

[0115] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
