DETAILED DESCRIPTION

[0047] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description in conjunction with the accompanying drawings and preferred embodiments.

[0048] The invention provides an independent suspension and a vehicle having the same. The independent suspension can conveniently adjust the castor angle of the vehicle without overall disassembly.

[0049] First embodiment

[0050] Figures 1 to 14 FIG. 2 shows the related structure of the independent suspension provided by the first embodiment of the present invention. Figures 1 to 5As shown, in this embodiment, the independent suspension includes a steering knuckle 10, a connecting ball head 20, a lower swing arm assembly 30, a first adjusting device 41 and a second adjusting device 42, and the first adjusting device 41 and the second adjusting device 42 are connected to both ends of the steering knuckle 10 through a connecting ball head 20. The end of the first adjusting device 41 away from the steering knuckle 10 is used to be connected to the vehicle body 50, such as connected to the longitudinal beam of the vehicle. The end of the second adjusting device 42 away from the steering knuckle 10 is connected to the lower swing arm assembly 30.

[0051] The first adjustment device 41 and the second adjustment device 42 both include a horizontal adjustment mechanism 43 and an angle adjustment mechanism 44. The horizontal adjustment mechanism 43 is used to change the fixed position of the two ends of the steering knuckle 10 in the vehicle X direction (i.e., the front-rear direction of the vehicle). Specifically, it can be reflected in the combination position of the two ends of the steering knuckle 10 and the corresponding connecting ball head 20 in the vehicle X direction. The angle adjustment mechanism 44 is used to change the angle between the axis of the connecting ball head 20 and the perpendicular line of the axis of the driving half shaft in the vehicle XZ plane. Specifically, it can be reflected in changing Figure 3 The angle represented by α.

[0052] When the caster angle of the independent suspension provided in this embodiment needs to be adjusted, the connection between the steering knuckle 10 and the first adjusting device 41 and the second adjusting device 42 can be removed first, and then the fixed position of the two ends of the steering knuckle 10 can be changed by the horizontal adjustment mechanism 43, and the angle between the axis of the connecting ball head 20 and the vertical line of the driving half-shaft axis can be changed by the angle adjustment mechanism 44. Finally, the first adjusting device 41 and the second adjusting device 42 are respectively connected to the two ends of the steering knuckle 10 through the corresponding connecting ball heads 20, and the caster angle of the vehicle can be completed, that is, Figure 3 Adjustment of the α angle.

[0053] In this embodiment, Figure 3 The angle α in the figure can roughly reflect the size of the caster angle. When making adjustments, if the positions of the connection points at both ends of the steering knuckle 10 are changed in the vehicle's X direction, the inclination angle of the steering knuckle 10 will change. At this time, it is necessary to adjust the angle between the axis of the connecting ball head 20 and the perpendicular line of the driving half-shaft axis to adapt to the above changes to ensure the stability of the connection between the connecting ball head 20 and the steering knuckle 10. By adjusting the above position and angle, the caster angle of the vehicle can be adjusted more conveniently without disassembling the entire vehicle.

[0054] It should be noted that in this embodiment, without changing the distance between the vehicle body 50 and the ground, after changing the positions of the two ends of the steering knuckle 10 in the vehicle X direction, the effective length of the steering knuckle 10 and the connecting ball head 20 as a whole will change. At this time, the effective length change of the steering knuckle 10 and the connecting ball head 20 can be adapted by changing the combined length of the connecting ball head 20 and the steering knuckle 10, that is, the length of the connecting stud part between the ball head part of the connecting ball head 20 and the connecting nut. Furthermore, the axes of the connecting ball heads 20 at the two ends of the steering knuckle 10 may not be on the same straight line, as long as the connection between the steering knuckle 10 and the connecting ball head 20 can be ensured to be stable and not subject to shear force sufficient to affect the safety of the vehicle.

[0055] Please refer to Figures 4 to 7 , the horizontal adjustment mechanism 43 includes an adjustment washer 431. In this embodiment, mounting holes 432 adapted to the adjustment washer 431 are provided at both ends of the steering knuckle 10, and the adjustment washer 431 is disposed in the mounting holes 432. A connecting hole 433 is formed on the adjusting washer 431, and the connecting stud of the connecting ball head 20 passes through the connecting hole 433 and is connected to the connecting nut to achieve the connection between the connecting ball head 20 and the steering knuckle 10. The end of the connecting ball head 20 away from the steering knuckle 10 is connected to the angle adjustment mechanism 44 (see FIG. Fig.11 ) are connected.

[0056] In this embodiment, the adjusting gasket 431 can have multiple models, and in each model, the position of the connecting hole 433 on the adjusting gasket 431 is different. By replacing the adjusting gasket 431 of different models, the fixed positions of the two ends of the steering knuckle 10 in the vehicle X direction can be changed.

[0057] Figure 7 In the figure, the solid line connection hole 433 represents the position of the connection hole 433 on the adjustment gasket 431 in one type of adjustment gasket 431, and the dotted line connection hole 433 represents the position of the connection hole 433 on the adjustment gasket 431 in another type of adjustment gasket 431.

[0058] Furthermore, if Figure 6 and Figure 7 As shown, in this embodiment, the adjusting gasket 431 is a waist-shaped gasket when viewed from the length direction, and is in an arc shape as a whole when viewed from the side, with its upper and lower surfaces both being arc-shaped surfaces, and the center of curvature of the arc-shaped surface facing the side where the middle of the steering knuckle 10 is located. The shape of the mounting hole 432 may correspond to the adjusting gasket 431. By setting the arc-shaped mounting hole 432 and the adjusting gasket 431, the adjusting gasket 431 can adapt to the needs of the angle adjustment mechanism 44 while changing the fixed positions of the two ends of the steering knuckle 10.

[0059] Please continue to refer to Figure 8 and Fig. 9 In order to ensure that the adjusting gasket 431 can be stably arranged in the mounting hole 432, a step surface (not shown in the figure) can be formed in the mounting hole 432, that is, the size of the bottom of the mounting hole 432 is smaller than the size of the top, and the diameter of the connecting nut is larger than the width of the bottom of the mounting hole 432. It should be noted that the top and bottom of the above-mentioned mounting hole 432 are based on the installation direction of the adjusting gasket 431. The top refers to the side of the mounting hole 432 away from the middle of the steering knuckle 10, and the bottom refers to the side of the mounting hole 432 close to the middle of the steering knuckle 10.

[0060] When installing the adjusting gasket 431 at the upper end of the steering knuckle 10, the adjusting gasket 431 is put into the mounting hole 432 from the top, the connecting bolt connecting the ball head 20 passes through the adjusting gasket 431 from top to bottom, and the connecting nut is tightened with the connecting bolt from the bottom of the mounting hole 432. At this time, the connecting nut will abut against the end surface of the bottom of the mounting hole 432. When the vehicle is running, the gravity of the vehicle will press the adjusting gasket 431 into the mounting hole 432.

[0061] When installing the adjusting gasket 431 at the lower end of the steering knuckle 10, the adjusting gasket 431 is placed upward into the mounting hole 432 from the bottom, and the connecting bolt of the connecting ball head 20 passes through the adjusting gasket 431 from top to bottom. The connecting nut is tightened with the connecting bolt from the top of the mounting hole 432, that is, from the bottom of the mounting hole 432. At this time, the connecting ball head 20 can provide an upward pulling force to the adjusting gasket 431, so that it is fastened in the mounting hole 432.

[0062] Please refer to Figures 10 to 14In this embodiment, the angle adjustment mechanism 44 includes a first fixed block 441, a second fixed block 442 and a fixed shaft 443. One end of the fixed shaft 443 is fixedly connected to the housing of the connecting ball head 20, and the other end is detachably clamped between the first fixed block 441 and the second fixed block 442. On the outer surface of one end of the fixed shaft 443 connected to the first fixed block 441 and the second fixed block 442, a plurality of first protrusions and first recesses arranged along the circumference thereof are provided, and these first recesses are formed between adjacent first protrusions. A semi-cylindrical groove 444 for accommodating the fixed shaft 443 is formed on each of the first fixed block 441 and the second fixed block 442, and a second recess and a second protrusion adapted to the first protrusion and the first recess are formed on the inner surface of the groove 444. When the fixed shaft 443 is sandwiched between the first fixed block 441 and the second fixed block 442, the second protrusion and the second depression in the groove 444 are respectively combined with the first depression and the first protrusion on the fixed shaft 443 to fix the fixed shaft 443 in the circumferential direction, so that the shell of the connecting ball head 20 and the first fixed block 441 and the second fixed block 442 do not rotate relative to each other. It can be understood that the positions of the first depression and the first protrusion on the fixed shaft 443 that match the second protrusion and the second depression change, that is, when the first depression and the first protrusion that match the second protrusion and the second depression are switched from the first depression and the first protrusion at the first position to the first depression and the first protrusion at the second position, the shell of the connecting ball head 20 has different combination postures relative to the first fixed block 441 and the second fixed block 442, and the angle between the axis of the connecting ball head 20 and the perpendicular line of the axis of the driving half shaft can be adjusted.

[0063] In this embodiment, a plurality of gear teeth 445 are formed on the outer surface of the fixed shaft 443 and the inner surface of the groove 444. It can be understood that the gear teeth 445 themselves can be the first protrusion or the second protrusion, and the first depression or the second depression can be formed between two gear teeth 445.

[0064] Further, the second fixing block 442 may be directly or indirectly connected to the corresponding vehicle body 50 or the lower swing arm assembly 30. The first fixing block 441 is detachably fixed to the second fixing block 442.

[0065] More specifically, Fig.10 As shown, in this embodiment, the first adjusting device 41 also includes a first connecting arm 45, which is fixed to the vehicle body 50 in a manner that it can swing up and down relative to the vehicle body 50, and the second fixed block 442 in the angle adjustment mechanism 44 is fixed to the first connecting arm 45, thereby fixing the first adjusting device 41 to the vehicle body 50.

[0066] In the second adjusting device 42 , the second fixing block 442 can be directly fixed on the lower swing arm assembly 30 to achieve fixation of the second adjusting device 42 and the lower swing arm assembly 30 .

[0067] Please continue to refer to Figures 11 to 14 In this embodiment, the first adjusting device 41 and the second adjusting device 42 are basically the same. The difference between the two in details can be reflected in the specific structure of the first fixing block 441 and the second fixing block 442, and the connection method between the first adjusting device 41 and the second adjusting device 42 and the vehicle body 50 and the lower control arm assembly 30.

[0068] Second embodiment

[0069] Please continue to refer to Figures 15 to 19 The independent suspension provided by the second embodiment of the present invention is basically the same as the first embodiment, and the difference between the two is that the structure and connection method of the horizontal adjustment mechanism 43 are different.

[0070] In the second embodiment of the present invention, the horizontal adjustment mechanism 43 also includes an adjustment pad 431, and the adjustment pad 431 is also provided with a connection hole 433. The adjustment pad 431 can also have multiple models, and in each model, the position of the connection hole 433 on the adjustment pad 431 is different. Fig.17 As shown in the figure, the connection hole 433 shown by the solid line is the position of the connection hole 433 in one model of the adjusting gasket 431, and the connection hole 433 shown by the dotted line is the position of the connection hole 433 in another model of the adjusting gasket 431.

[0071] The second embodiment is different from the first embodiment in that the mounting hole 432 is no longer disposed on the steering knuckle 10 , that is, the adjusting gasket 431 is no longer disposed on the steering knuckle 10 .

[0072] At the upper end of the steering knuckle 10, a mounting hole 432 is directly opened on the vehicle body 50, and the adjusting gasket 431 is arranged in the mounting hole 432 on the vehicle body 50. The horizontal adjustment mechanism 43 also includes a first connecting bolt 434, which passes through the connecting hole 433 on the adjusting gasket 431 to fix the first connecting arm 45 directly on the vehicle body 50.

[0073] At the lower end of the steering knuckle 10, a mounting hole 432 is directly opened on the second fixing block 442, an adjusting gasket 431 is arranged in the mounting hole 432, and a first connecting bolt 434 directly passes through a connecting hole 433 on the adjusting gasket 431 from below the second fixing block 442 to fix the second fixing block 442 to the lower swing arm assembly 30.

[0074] In this embodiment, the mounting hole 432 at the upper end of the steering knuckle 10 is set on the vehicle body 50, the mounting hole 432 at the lower end of the steering knuckle 10 is set on the second fixing block 442, and different types of adjustment gaskets 431 are used, so that the positions of the upper and lower ends of the steering knuckle 10 in the X direction of the vehicle can also be adjusted. Accordingly, this embodiment also needs to be equipped with an angle adjustment mechanism 44 to adapt to the position adjustment of the upper and lower ends of the steering knuckle 10 in the X direction of the vehicle. The specific structure of the angle adjustment mechanism 44 in this embodiment is the same as that in the first embodiment, and will not be repeated here.

[0075] It should be noted that in this embodiment, two connection holes 433 can be set on the same adjustment gasket 431 of the first adjustment device 41 at the same time. When connecting, two first connection bolts 434 are used at the same time to connect the parts, which can ensure the strength of the connection. Correspondingly, in multiple different types of adjustment gaskets 431, the positions of the two connection holes 433 are different, but the distance between the two connection holes 433 in various types of adjustment gaskets 431 should be consistent. That is, Fig.17 The distance between the two connecting holes 433 should be β.

[0076] Furthermore, in this embodiment, the adjusting gasket 431 may be waist-shaped as a whole, and may be flat-plate-shaped when viewed from the side. The structure of the mounting hole 432 is adapted to the adjusting gasket 431 .

[0077] Correspondingly, in the present embodiment, only one circular hole matching with the connecting bolt of the connecting ball head 20 is provided at the end of the steering knuckle 10 .

[0078] Compared with the first embodiment, the second embodiment adopts flat adjustment gaskets at both ends of the steering knuckle 10, and the connection method thereof is also changed. However, it should be noted that in the first embodiment, the second embodiment and each of the following embodiments, although both the first adjustment device 41 and the second adjustment device 42 need to be adjusted by the horizontal adjustment mechanism 43 and the angle adjustment mechanism 44, the specific implementation of each adjustment mechanism can be mixed in the methods of each embodiment. For example, in one embodiment, the first adjustment device 41 at the upper end of the steering knuckle 10 can adopt the first adjustment device 41 in the first embodiment, and the second adjustment device 42 at the lower end of the steering knuckle 10 can adopt the second adjustment device 42 in the second embodiment. In other words, under the premise of the basic concept of the present invention, there is no restriction on the selection of the first adjustment device 41 and the second adjustment device 42 between the various embodiments.

[0079] Third embodiment

[0080] like Fig. 20 and Fig.21As shown, the independent suspension provided by the third embodiment of the present invention is basically the same as the first two embodiments, except that, in the present embodiment, in the second adjusting device 42, a connecting plate 4421 is provided on the second fixing block 442 of the angle adjusting mechanism 44, one end of the connecting plate 4421 is connected to the second fixing block 442, and the other end extends upward and away from the first fixing block 441. In other words, the connecting plate 4421 extends upward obliquely toward the lower swing arm assembly 30. The above-mentioned mounting hole 432 is formed on the connecting plate 4421, and the adjusting gasket 431 can be installed into the mounting hole 432 from the side of the connecting plate 4421 away from the second fixing block 442, and the first connecting bolt 434 is installed into the connecting hole 433 of the adjusting gasket 431 from between the connecting plate 4421 and the first fixing block 441, so as to fix the second fixing block 442 to the lower swing arm assembly 30.

[0081] The shape of the adjusting pad 431 may be the same as that in the second embodiment. The first adjusting device 41 in this embodiment may be the same as the corresponding structure in the first embodiment or the second embodiment.

[0082] Fourth embodiment

[0083] like Figures 22 to 24 As shown, the independent suspension provided by the fourth embodiment of the present invention is basically the same as the first three embodiments, except that, in the present embodiment, in the first adjustment device 41, a mounting hole 432 is formed on the second fixing block 442 of the angle adjustment mechanism 44, and the adjustment gasket 431 is disposed in the mounting hole 432. The first connecting bolt 434 passes through the connecting hole 433 to fix the second fixing block 442 of the angle adjustment mechanism 44 to the first connecting arm 45.

[0084] The shape of the adjusting gasket 431 can be as shown in the second embodiment. The second adjusting device 42 in this embodiment can be the same as the corresponding structure in the first embodiment, the second embodiment or the third embodiment.

[0085] Fifth embodiment

[0086] like Figures 25 to 27 As shown, the independent suspension provided by the fifth embodiment of the present invention is basically the same as the first four embodiments, except that, in the first four embodiments, at each end of the steering knuckle 10, there is one mounting hole 432 and one adjusting gasket 431. In this embodiment, for the first adjusting device 41, a mounting hole 432 can be provided at the upper end of the steering knuckle 10 and on the vehicle body 50, and an adjusting gasket 431 can be provided in each mounting hole 432. It can be understood that in order to adapt to the surrounding structure, the mounting hole 432 on the steering knuckle 10 can be the same as the first embodiment, that is, it is arc-shaped when viewed from the side; while the mounting hole 432 provided on the vehicle body 50 can be flat when viewed from the side.
