[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0028] like Figure 1 As shown, the suspension stand 100 of the embodiment of the utility model comprises a base 1, a connecting seat 2, a sub-frame bracket 3 and a shock absorber bracket 4, and the connecting seat 2 is connected to the base 1 through a connecting member 5. The base 1 is provided with a slide groove 111 extending along its height direction, and the connecting member 5 is slidably arranged in the slide groove 111 along the height direction of the base 1. The sub-frame bracket 3 is connected to the base 1, and the shock absorber bracket 4 is connected to the connecting seat 2. The sub-frame bracket 3 is provided with a sub-frame connecting portion, and the shock absorber bracket 4 is provided with a shock absorber connecting portion.

[0029] When the suspension test bench 100 of the embodiment of the utility model is used for suspension performance test research, the sub-frame of the suspension is connected to the sub-frame connection part of the sub-frame bracket 3, and the shock absorber of the suspension is connected to the shock absorber connection part of the shock absorber bracket 4, so that the suspension is installed and fixed on the suspension bench 100, and then the suspension performance test research can be carried out. The connecting seat 2 is connected to the base 1 through the connecting member 5, and the base 1 is provided with a slide groove 111 extending along its height direction. When the connecting member 5 slides along the height direction of the base 1, the relative position of the connecting seat 2 and the base 1 can be adjusted along the height direction of the base 1, thereby adjusting the relative position between the shock absorber and the sub-frame, thereby realizing the adjustment of the suspension posture, realizing the performance research of the suspension under different postures, and improving the adaptability of the suspension bench. For example, the suspension bench 100 can be used to study the effect of the suspension posture on the suspension mode and VTF (vibration transfer function).

[0030] In addition, by arranging the connecting member 5 in the slide groove 111 and utilizing the slide groove 111 to cooperate with the connecting member 5, not only can the slide groove 111 be used to guide the moving direction of the connecting member 5 to avoid deflection of the connecting seat 2 during movement, thereby improving the adjustment stability of the connecting seat 2; but also the continuous adjustment of the position of the connecting seat 2 can be achieved, thereby achieving continuous adjustment of the suspension posture and improving the adjustment accuracy.

[0031] Alternatively, if Figures 2 to 4 As shown, the orthographic projection of the slide groove 111 along the height direction of the base 1 and the orthographic projection of the connector 5 along the height direction of the base 1 are both T-shaped. In other words, the slide groove 111 is a T-shaped groove, and the connector 5 is a T-shaped connector.

[0032] For example, the connector 5 is a T-bolt, the bolt head of which is disposed in the slide groove 111 and can slide along the extension direction of the slide groove 111. The screw of the T-bolt is threadedly connected to the nut, and the nut is used to press the connection seat 2 onto the base 1 to achieve the connection between the connection seat 2 and the base 1. When the position of the connection seat 2 needs to be adjusted along the height direction of the base 1, the nut is screwed to release the pressing effect of the nut on the connection seat 2, and at this time, the bolt head of the T-bolt can slide along the extension direction of the T-slot.

[0033] By setting the slide groove 111 as a T-shaped groove and the connecting member 5 as a T-shaped connecting member, the guiding effect of the slide groove 111 on the connecting member 5 can be improved, and the adjustment stability of the connecting seat 2 can be further improved.

[0034] Alternatively, if Figure 3As shown, the length of the slide groove 111 is 400 mm, and the slide groove 111 includes a first width section 1111 and a second width section 1112. The width K1 of the first width section 1111 is 40 mm, and the length C1 of the first width section 1111 is 16 mm; the width K1 of the second width section 1112 is 22 mm, and the length C2 of the second width section 1112 is 24 mm. The length of the slide groove 111 is the size of the slide groove 111 in the height direction of the base 1.

[0035] Optionally, the connecting member 5 is a T-shaped bolt, the diameter of the screw of the T-shaped bolt is 20 mm, and the length of the screw of the T-shaped bolt is less than or equal to 50 mm.

[0036] In some embodiments, Figure 2 and Figure 4 As shown, the base 1 includes a column 11, and a slide groove 111 is provided on the column 11. Figure 5 As shown, the connecting seat 2 includes a cross beam 21 , the cross beam 21 is connected to the column 11 through a connecting piece 5 , and the shock absorber bracket 4 is connected to the cross beam 21 .

[0037] By configuring the base 1 to include a column 11 and the connecting seat 2 to include a crossbeam 21 , the structures of the base 1 and the connecting seat 2 are simplified, and the processing and manufacturing of the base 1 and the connecting seat 2 are facilitated, which is beneficial to reducing the manufacturing cost of the suspension stand 100 .

[0038] Alternatively, if Figure 1 As shown, the suspension stand 100 includes a plurality of column groups, the plurality of column groups are arranged at intervals along a first direction, each column group includes a plurality of columns 11, and the plurality of columns 11 in the same column group are arranged at intervals along a second direction. There are a plurality of crossbeams 21, the plurality of crossbeams 21 are arranged at intervals along the first direction, and the crossbeams 21 extend along the second direction. The crossbeams 21 correspond to the column groups one by one, and each crossbeam 21 is connected to the plurality of columns 11 in the corresponding column group. The first direction and the second direction are both perpendicular to the height direction of the column 11, and the first direction is perpendicular to the second direction.

[0039] In order to make the technical solution of the present invention easier to understand, the following example is used to further describe the technical solution of the present invention, in which the height direction of a column 11 is consistent with the up-down direction, the first direction is consistent with the left-right direction, and the second direction is consistent with the front-back direction. Figure 1 , Figure 2 and Figure 5 As shown, the left-right direction and the front-back direction are Figure 1 , Figure 2 , Figure 4 and Figure 5 shown.

[0040] For example, Figure 1As shown, the suspension stand 100 includes two column groups, the two column groups are arranged at intervals in the left-right direction, each column group includes two columns 11, and the two columns 11 in the same column group are arranged at intervals in the front-back direction. There are two cross beams 21, the cross beams 21 extend in the front-back direction, and the two cross beams 21 are arranged at intervals in the left-right direction. The cross beam 21 on the left side is connected to the two columns 11 on the left side, and the cross beam 21 on the right side is connected to the two columns 11 on the right side. A subframe bracket 3 is provided on the side of each column 11, and each cross beam 21 is connected to two shock absorber brackets 4.

[0041] By configuring the suspension stand 100 to have the above structure, the structure of the suspension stand 100 can be simplified and the cost of the suspension stand 100 can be reduced while ensuring the structural strength of the suspension stand 100 .

[0042] Alternatively, if Figure 5 As shown, the connection seat 2 further includes a connection plate 22, which is disposed at the end of the cross beam 21 and connected to the cross beam 21. The cross beam 21 and the connection plate 22 can be welded. The connection plate 22 has a first surface facing the cross beam 21 and a second surface facing the column 11, the orthographic projection of the cross beam 21 on the first surface is located within the first surface, and the second surface is connected to the column 11.

[0043] For example, both ends of the cross beam 21 are connected with connecting plates 22 , and a portion of the connecting plate 22 located outside the edge of the cross beam 21 is provided with a through hole, and the connecting member 5 passes through the through hole to achieve the connection between the cross beam 21 and the column 11 .

[0044] By providing a connecting plate 22 at the end of the crossbeam 21, connecting it to the column 11 via the connecting plate 22, and setting the orthographic projection of the crossbeam 21 on the first surface to be located within the first surface, it is beneficial to increase the connection area between the crossbeam 21 and the column 11, improve the connection reliability between the crossbeam 21 and the column 11, and thereby improve the reliability of the suspension stand 100.

[0045] Optionally, the base 1 further includes a bottom plate 12 , and the bottom ends of the upright posts 11 and the sub-frame bracket 3 are both connected to the bottom plate 12 .

[0046] For example, Figure 1 As shown, the lower end of the column 11 and the lower end of the sub-frame bracket 3 are both connected to the bottom plate 12. The column 11 and the bottom plate 12 can be welded; the sub-frame bracket 3 and the bottom plate 12 can be welded.

[0047] By connecting the column 11 and the sub-frame bracket 3 to the bottom plate 12, the sub-frame bracket 3 is connected to the column 11 using the bottom plate 12, which facilitates the connection between the sub-frame bracket 3 and the base 1, thereby facilitating the processing and manufacturing of the base 1, which is beneficial to reducing the manufacturing cost of the suspension stand 100.

[0048] Optionally, the orthographic projection of the column 11 on the surface of the bottom plate 12 facing the column 11 is located within the surface of the bottom plate 12 facing the column 11. In other words, the surface area of ​​the column 11 facing the bottom plate 12 is smaller than the surface area of ​​the bottom plate 12 facing the column 11.

[0049] It is understandable that when performing a suspension performance test, the base plate 12 needs to be placed on the test platform and connected to the test platform to achieve the fixation of the suspension test bench 100 .

[0050] By setting the orthographic projection of the column 11 on the surface of the base plate 12 facing the column 11 to be located within the surface of the base plate 12 facing the column 11, it is beneficial to increase the connection area between the suspension test bench 100 and the test platform and improve the connection reliability between the suspension test bench 100 and the test platform.

[0051] Alternatively, if Figure 2 and Figure 4 As shown, the cross-sectional area of ​​the column 11 gradually increases in the direction approaching the bottom plate 12. The cross-sectional area of ​​the column 11 refers to the cross-sectional area of ​​the column 11 cut by a plane perpendicular to the height direction of the column 11.

[0052] For example, the cross-sectional area of ​​the pillar 11 gradually increases from top to bottom.

[0053] It is understandable that when conducting a suspension performance test, the bottom end of the column 11 will be subjected to a greater load. By setting the cross-sectional area of ​​the column 11 to gradually increase in the direction approaching the bottom plate 12, when the overall volume of the column 11 is relatively small, it is beneficial to increase the structural strength of the bottom end of the column 11 and improve the reliability of the suspension test bench 100.

[0054] Alternatively, if Figure 2 and Figure 4 As shown, the base 1 includes a first reinforcing rib 13, and the bottom plate 12 and the column 11 are both connected to the first reinforcing rib 13. The thickness of the first reinforcing rib 13 may be greater than or equal to 20 mm.

[0055] For example, the first reinforcing rib 13 is a first reinforcing plate, the lower surface of the first reinforcing plate is connected to the bottom plate 12, and the side of the first reinforcing plate facing the column 11 is connected to the column 11. The first reinforcing rib 13 and the bottom plate 12 can be welded, and the first reinforcing rib 13 and the column 11 can be welded.

[0056] By providing the first reinforcing rib 13 connected to the bottom plate 12 and the column 11, it is beneficial to improve the overall strength and rigidity of the base 1, and provide sufficient installation rigidity for the suspension. In the process of studying the suspension performance, it will not be affected by the characteristics of the suspension stand 100 itself, and the evaluation accuracy of the suspension characteristics is improved.

[0057] Alternatively, if Figure 2and Figure 4 As shown, there are multiple first reinforcing ribs 13 , and the multiple first reinforcing ribs 13 are arranged at intervals along the circumference of the column 11 .

[0058] For example, the column 11 is a rectangular column, and two first reinforcing ribs 13 are disposed on each side of the column 11 .

[0059] The provision of a plurality of first reinforcing ribs 13 is beneficial for further improving the overall strength and rigidity of the base 1 and further improving the accuracy of evaluating the suspension characteristics.

[0060] Alternatively, if Figure 2 and Figure 4 As shown, the base 1 includes a second reinforcing rib 14 , and the bottom plate 12 and the sub-frame bracket 3 are both connected to the second reinforcing rib 14 .

[0061] For example, the second reinforcing rib 14 is a second reinforcing plate, the lower surface of the second reinforcing plate is connected to the bottom plate 12, and the side of the second reinforcing plate facing the sub-frame bracket 3 is connected to the sub-frame bracket 3. The second reinforcing rib 14 and the bottom plate 12 can be welded; the second reinforcing rib 14 and the sub-frame bracket 3 can be welded. The thickness of the second reinforcing rib 14 can be greater than or equal to 20 mm.

[0062] The second reinforcing rib 14 connected to the bottom plate 12 and the sub-frame bracket 3 is provided to improve the strength and rigidity of the sub-frame bracket 3 and provide sufficient installation rigidity for the sub-frame. In the process of studying the suspension performance, the suspension test bench 100 will not be affected by its own characteristics, thereby improving the accuracy of evaluating the suspension characteristics.

[0063] Alternatively, if Figure 2 and Figure 4 As shown, there are multiple second reinforcing ribs 14 , and the multiple second reinforcing ribs 14 are arranged at intervals along the circumferential direction of the sub-frame bracket 3 .

[0064] For example, the sub-frame bracket 3 is cylindrical, and the plurality of second reinforcing ribs 14 are evenly spaced along the circumference of the sub-frame bracket 3 .

[0065] The provision of a plurality of second reinforcing ribs 14 is beneficial for further improving the strength and rigidity of the sub-frame bracket 3 and further improving the accuracy of evaluating the suspension characteristics.

[0066] Alternatively, if Figure 2 and Figure 4 As shown, the sub-frame bracket 3 includes a column 31 and a boss 32, the column 31 extends in the height direction of the base 1, the bottom end of the column 31 is connected to the bottom plate 12, and the boss 32 is arranged at the top end of the protruding body and is connected to the column 31. The boss 32 is provided with a threaded hole 321 extending in the height direction of the base 1, and the threaded hole 321 forms a sub-frame connection portion.

[0067] The diameter of the column 31 may be greater than 150 mm, and the height of the column 31 may be 250 mm.

[0068] For example, the sub-frame bracket 3 is cylindrical, the column 31 is arranged below the boss 32, the lower end of the column 31 is connected to the base plate 12, and the threaded hole 321 extends in the up-down direction. A bushing is connected to the sub-frame, and the bushing is threadedly connected to the threaded hole 321 through a bolt. The cross-sectional area of ​​the column 31 is larger than the cross-sectional area of ​​the boss 32, the end of the column 31 away from the boss 32 is connected to the base plate 12, and the end of the boss 32 away from the column 31 is used to connect to the sub-frame. Among them, the cross-sectional area of ​​the column 31 refers to: the cross-sectional area of ​​the column 31 cut by a plane perpendicular to the height direction of the base 1; the cross-sectional area of ​​the boss 32 refers to: the cross-sectional area of ​​the boss 32 cut by a plane perpendicular to the height direction of the base 1.

[0069] This is beneficial for further improving the rigidity of the subframe bracket 3 and further improving the accuracy of evaluating the suspension characteristics.

[0070] In some embodiments, the shock absorber bracket 4 is detachably connected to the connecting seat 2 .

[0071] For example, the shock absorber bracket 4 is connected to the connecting seat 2 by bolts.

[0072] By arranging the shock absorber bracket 4 to be detachably connected to the connecting seat 2 , the shock absorber bracket 4 can be replaced, so that the shock absorber bracket 4 can match shock absorbers of different structural forms, thereby improving the versatility of the suspension stand 100 .

[0073] Alternatively, if Figure 5 As shown, the shock absorber bracket 4 is provided with a connecting hole 41, and the shock absorber is connected to the connecting hole 41 by bolts. The connecting hole 41 forms a shock absorber connecting portion.

[0074] For example, the shock absorber bracket 4 is provided with three connection holes 41 , and the shock absorber is connected to the shock absorber bracket 4 by three bolts.

[0075] This facilitates the connection and disassembly between the shock absorber and the shock absorber bracket 4 .

[0076] Optionally, the height of the shock absorber bracket 4 is greater than 20 mm.

[0077] Optionally, the base 1 is formed by welding steel plates, and the thickness of the steel plates is greater than or equal to 40 mm.

[0078] Thereby, the base 1 is ensured to have sufficient strength and rigidity, and the evaluation accuracy of the suspension characteristics is further improved.

[0079] In some embodiments, the suspension test bench 100 further includes a test platform and a support frame, the bottom end of the base 1 is connected to the test platform, the bottom surface of the support frame is in contact with the test platform, and the top surface of the support frame forms a support surface for supporting the wheel. The test platform can be an iron plate or a steel plate.

[0080] When conducting suspension performance test research, the wheel is placed on the supporting surface of the support frame, and the contact point between the wheel and the supporting surface is the wheel grounding point.

[0081] Optionally, the support frame includes a plurality of support sub-frames, and the plurality of support sub-frames are stacked along the height direction of the base 1 .

[0082] By setting the support frame to include a plurality of support sub-frames, the height of the support frame can be increased or decreased by increasing or decreasing the number of support sub-frames, thereby adjusting the position of the shock absorber connection part and the wheel grounding point, so as to load different preload forces on the suspension, and realize the study of the effect of preload force on suspension performance. For example, the seismic isolation performance of the bushing under different preload forces and the change of suspension characteristics are studied.

[0083] Optionally, the supporting subframe is a supporting plate.

[0084] Optionally, there are multiple support frames, and the heights of any two support frames are different.

[0085] By increasing the number of support frames to multiple and making the heights of any two support frames different, the height of the support frames can be changed by replacing different support frames, thereby adjusting the position of the shock absorber connection part and the wheel grounding point to load different preload forces on the suspension, thereby realizing the study of the effect of preload force on suspension performance.

[0086] Optionally, the suspension stand 100 is made entirely of steel.

[0087] The suspension stand 100 of the embodiment of the utility model has low cost, simple structure, and is easy to maintain and disassemble; by sliding the connecting member 5 along the extension direction of the slide groove 111, the suspension posture can be adjusted, and the effect of the suspension posture on the suspension performance can be studied; by replacing the support frame or adding or reducing the support sub-frame, the relative position of the shock absorber connection part and the wheel grounding point can be controlled, and different preload forces can be loaded on the suspension, which is helpful to study the influence of the preload force on the suspension performance; by replacing the shock absorber bracket 4, the suspension stand 100 can be suitable for shock absorbers of different structures, thereby improving the versatility of the suspension stand 100.

[0088] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
