[0022] 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 should not be understood as limiting the present invention.

[0023] The independent suspension 100 of a vehicle 1000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings. Figure 1-Figure 6 As shown, the independent suspension 100 of the vehicle 1000 according to the embodiment of the present invention includes a first mounting portion 11 , a second mounting portion 12 , a half beam 2 and a trailing arm 3 .

[0024] The first mounting portion 11 and the second mounting portion 12 are spaced apart along a first direction. When the independent suspension 100 is mounted on the vehicle 1000, the first direction is consistent with the width direction of the vehicle 1000. The half beam 2 is rotatably mounted on the first mounting portion 11 and the second mounting portion 12, and the rotation axis of the half beam 2 extends along the first direction. The trailing arm 3 is connected to the half beam 2.

[0025] Since the half beam 2 is rotatably arranged and the longitudinal arm 3 is connected to the half beam 2, the longitudinal arm 3 can also rotate around the rotation axis of the half beam 2. Therefore, during the driving process of the vehicle 1000, the longitudinal arm 3 and the half beam 2 can buffer the vertical impact force of the road on the vehicle 1000 under the cooperation of the elastic element and the shock absorber, thereby preventing the vertical impact force of the road on the vehicle 1000 from being transmitted to the body of the vehicle 1000, so as to improve the driving stability and riding comfort of the vehicle 1000.

[0026] Whether the vehicle 1000 is traveling or stationary, the gravity of the vehicle 1000 acts on the wheel through the elastic element, the longitudinal arm 3 and the wheel axle in turn, thereby causing the wheel to generate a reaction force. Since the elastic element's point of application does not coincide with the wheel's point of application, a lever arm is formed, and then the reaction force and the lever arm generate a torque. The longitudinal arm 3 and the half beam 2 can bear the component torque of the torque in the vertical direction, and can transfer the component torque to the chassis of the vehicle 1000 through the first mounting portion 11 and the second mounting portion 12. Specifically, under the action of the component torque, one of the first mounting portion 11 and the second mounting portion 12 is subjected to pressure, and the other of the first mounting portion 11 and the second mounting portion 12 is subjected to tension.

[0027] The elastic element application point may be the connection point between the elastic element and the longitudinal arm 3. The center line of the wheel axle is located in the first horizontal plane, and the intersection of the projection of the midline of the wheel in the first direction on the first horizontal plane along the vertical direction and the center line of the wheel axle may be the wheel application point.

[0028] Moreover, by rotatably arranging the half beam 2 at the first mounting portion 11 and the second mounting portion 12, that is, performing two-point movable mounting and positioning of the half beam 2, the half beam 2 and the longitudinal arm 3 are sufficient to bear the horizontal force generated by the wheels when the vehicle body rolls (for example, when turning), the vehicle body shakes horizontally, and brakes. Furthermore, the half beam 2 and the longitudinal arm 3 transmit the horizontal force to the chassis of the vehicle 1000 through the first mounting portion 11 and the second mounting portion 12.

[0029] That is to say, since the first mounting portion 11 and the second mounting portion 12 are both mounted on the chassis of the vehicle 1000, the first mounting portion 11 and the second mounting portion 12 are substantially located in the same horizontal plane, and thus the half beam 2, the longitudinal arm 3, the first mounting portion 11 and the second mounting portion 12 can bear forces in any direction (e.g., front, back, left, and right) on the horizontal plane.

[0030] Therefore, the independent suspension 100 according to the embodiment of the present invention does not need to set multiple directional links or various complex arms, and has the advantages of simple and reliable structure, small space occupation, easy layout, easy maintenance, and low manufacturing cost.

[0031] like Figure 1-Figure 6 As shown, the vehicle 1000 according to the embodiment of the present invention includes a chassis, a first independent suspension, a second independent suspension, a first wheel 210 and a second wheel 220. Both the first independent suspension and the second independent suspension can be the independent suspension 100 according to the embodiment of the present invention. The first mounting portion 11 and the second mounting portion 12 of the first independent suspension are arranged on the chassis, and the first mounting portion 11 and the second mounting portion 12 of the second independent suspension are arranged on the chassis. The first wheel 210 is connected to the longitudinal arm 3 of the first independent suspension, and the second wheel 220 is connected to the longitudinal arm 3 of the second independent suspension. The chassis can be a part of the body of the vehicle 1000.

[0032] The first independent suspension and the second independent suspension are arranged in a row along a first direction, the first wheel 210 and the second wheel 220 are arranged at intervals along the first direction, and the first direction is consistent with the width direction of the vehicle 1000 .

[0033] like Figure 1-Figure 6 As shown, the independent suspension 100 includes a first mounting portion 11 , a second mounting portion 12 , a half beam 2 and a trailing arm 3 .

[0034] The first mounting portion 11 and the second mounting portion 12 are spaced apart on the chassis along the first direction. In a specific example of the present invention, the first mounting portion 11 and the second mounting portion 12 are directly disposed on the chassis. For example, the first mounting portion 11 and the second mounting portion 12 are directly welded to the chassis, or the first mounting portion 11 and the second mounting portion 12 are mounted on the chassis by bolts.

[0035] In another specific example of the present invention, the independent suspension 100 further includes a base plate 4, the base plate 4 is provided on the chassis, the first mounting portion 11 and the second mounting portion 12 are provided on the base plate 4, that is, the first mounting portion 11 and the second mounting portion 12 are provided on the chassis through the base plate 4. For example, the base plate 4 can be welded to the chassis or mounted to the chassis by bolts, and the first mounting portion 11 and the second mounting portion 12 can be welded to the base plate 4 or mounted to the base plate 4 by bolts.

[0036] The half beam 2 is rotatably disposed on the first mounting portion 11 and the second mounting portion 12 , and the rotation axis of the half beam 2 extends along the first direction. The longitudinal arm 3 is connected to the half beam 2 .

[0037] like Figure 1 As shown, the half beam 2 extends along the first direction, and has a first end 21 and a second end 22 opposite to each other in the first direction, the first end 21 is rotatably disposed on the first mounting portion 11, and the second end 22 is rotatably disposed on the second mounting portion 12. This can make the structure of the independent suspension 100 simpler and more reasonable.

[0038] Specifically, the first mounting portion 11 has a first mounting hole, which passes through the first mounting portion 11 along the first direction, and at least a portion of the first end portion 21 is rotatably fitted in the first mounting hole. The second mounting portion 12 has a second mounting hole, which passes through the second mounting portion 12 along the first direction, and at least a portion of the second end portion 22 is rotatably fitted in the second mounting hole.

[0039] like Figure 1 As shown, the independent suspension 100 further includes a first limiting portion 51 and a second limiting portion 52, and the first limiting portion 51 and the second limiting portion 52 are arranged on the half beam 2. The first mounting portion 11 and the second mounting portion 12 are located between the first limiting portion 51 and the second limiting portion 52 in the first direction, or the first limiting portion 51 and the second limiting portion 52 are located between the first mounting portion 11 and the second mounting portion 12 in the first direction.

[0040] The first limiting portion 51 cooperates with the first mounting portion 11, and the second limiting portion 52 cooperates with the second mounting portion 12. Thus, the first limiting portion 51 and the second limiting portion 52 can be prevented from moving in the first direction, thereby further preventing the half beam 2 and the trailing arm 3 from moving in the first direction, so as to make the structure of the independent suspension 100 more reasonable and stable.

[0041] Optionally, the first limiting portion 51 may be a limiting nut or a limiting pin, and the second limiting portion 52 may be a limiting nut or a limiting pin.

[0042] For example, the first direction is the left-right direction. Figure 1 As shown by arrow A in FIG. 1 , the first end 21 of the half beam 2 is the left end of the half beam 2 , and the second end 22 is the right end of the half beam 2 .

[0043] like Figure 1 As shown, the first limiting portion 51 is provided at the first end portion 21 of the half beam 2, the first limiting portion 51 is located on the left side of the first mounting portion 11, and the right side surface of the first limiting portion 51 abuts against or is adjacent to the left side surface of the first mounting portion 11. The second limiting portion 52 is provided at the second end portion 22 of the half beam 2, the second limiting portion 52 is located on the right side of the second mounting portion 12, and the left side surface of the second limiting portion 52 abuts against or is adjacent to the right side surface of the second mounting portion 12. In this way, the half beam 2 and the trailing arm 3 can be further prevented from moving along the first direction, so that the structure of the independent suspension 100 is more reasonable and stable.

[0044] like Figure 1 As shown, the end 31 of the trailing arm 3 is connected to the first portion of the half beam 2, and the first portion of the half beam 2 is located between the first end 21 and the second end 22 of the half beam 2 in the first direction. In other words, the connection between the trailing arm 3 and the half beam 2 is located between the first end 21 and the second end 22 of the half beam 2 in the first direction.

[0045] like Figure 2 As shown, the end 31 of the longitudinal arm 3 is connected to the second end 22 of the half beam 2, and the second mounting portion 12 is located between the longitudinal arm 3 and the first mounting portion 11 in the first direction. As a result, the first mounting portion 11 can be adjacent to the middle of the body (the chassis) of the vehicle 1000 relative to the second mounting portion 12 in the first direction, and the second mounting portion 12 can be adjacent to the edge of the body of the vehicle 1000 or located on the outside of the body of the vehicle 1000 in the first direction, so that the longitudinal arm 3 is located on the outside of the body of the vehicle 1000. As a result, when the vehicle 1000 is impacted by the ground, the upward swing (rotation) amplitude of the longitudinal arm 3 will not be limited by the body (the chassis) of the vehicle 1000, so that the longitudinal arm 3 has a larger swing amplitude, so that the longitudinal arm 3 and the half beam 2 can buffer the greater vertical impact force of the road on the vehicle 1000, further improving the driving stability and riding comfort of the vehicle 1000.

[0046] like Figure 3As shown, the independent suspension 100 further includes a mounting rod 61, which extends along the first direction. The half beam 2 includes a beam body 23, a first support beam 24 and a second support beam 25, wherein a first end 241 of the first support beam 24 is connected to the beam body 23, a first end 251 of the second support beam 25 is connected to the beam body 23, and the trailing arm 3 is connected to the beam body 23.

[0047] In one embodiment of the present invention, the mounting rod 61 is fixed to the first mounting portion 11 and the second mounting portion 12. The mounting rod 61 is fixed to the first mounting portion 11 and the second mounting portion 12, which means that the mounting rod 61 cannot rotate relative to the first mounting portion 11 and the second mounting portion 12 around the rotation axis of the half beam 2. The second end 242 of the first support beam 24 is rotatably mounted on the mounting rod 61, and the second end 252 of the second support beam 25 is rotatably mounted on the mounting rod 61. The second end 242 of the first support beam 24 and the second end 252 of the second support beam 25 are spaced apart along the first direction. In this way, the structures of the independent suspension 100 and the vehicle 1000 can be made more reasonable.

[0048] Since the rotation axis of the half beam 2 extends along the first direction, the rotation axis of the first support beam 24 and the rotation axis of the second support beam 25 both extend along the first direction, and the rotation axis of the first support beam 24 and the rotation axis of the second support beam 25 substantially coincide with each other.

[0049] In another embodiment of the present invention, the mounting rod 61 is rotatably disposed on the first mounting portion 11 and the second mounting portion 12, and the rotation axis of the mounting rod 61 extends along the first direction. The second end 242 of the first support beam 24 is sleeved on the mounting rod 61, and the second end 252 of the second support beam 25 is sleeved on the mounting rod 61. In this way, the structures of the independent suspension 100 and the vehicle 1000 can be more reasonable.

[0050] like Figure 3 As shown, the beam body 23 extends along the first direction, or the angle between the extending direction of the beam body 23 and the first direction is less than or equal to a preset value. The beam body 23 has a first end 231 and a second end 232 opposite to each other in the length direction thereof, that is, the beam body 23 has a first end 231 and a second end 232 opposite to each other in the first direction. The end 31 of the longitudinal arm 3 is connected to the first end 231 of the beam body 23, the first end 241 of the first support beam 24 is connected to the first end 231 of the beam body 23, and the first end 251 of the second support beam 25 is connected to the second end 232 of the beam body 23. In this way, the structures of the half beam 2 and the independent suspension 100 can be more reasonable.

[0051] The second end 242 of the first support beam 24 is adjacent to the first mounting portion 11 in the first direction, and the second end 252 of the second support beam 25 is adjacent to the second mounting portion 12 in the first direction. This can further prevent the half beam 2 and the trailing arm 3 from moving along the first direction, thereby making the structure of the independent suspension 100 more reasonable and stable.

[0052] like Figure 3 As shown, the independent suspension 100 further includes a first limiting portion 51 and a second limiting portion 52, and the first limiting portion 51 and the second limiting portion 52 are arranged on the mounting rod 61. The first mounting portion 11 is located between the first limiting portion 51 and the second end portion 242 of the first support beam 24 in the first direction, and the second mounting portion 12 is located between the second limiting portion 52 and the second end portion 252 of the second support beam 25 in the first direction. In this way, the mounting rod 61, the half beam 2 and the trailing arm 3 can be further prevented from moving in the first direction, so that the structure of the independent suspension 100 is more reasonable and stable.

[0053] Optionally, the extension direction of the first support beam 24 is perpendicular to the first direction, and the extension direction of the second support beam 25 is perpendicular to the first direction. The right side surface of the first limiting portion 51 abuts against or is adjacent to the left side surface of the first mounting portion 11, and the left side surface of the second end portion 242 of the first support beam 24 abuts against or is adjacent to the right side surface of the first mounting portion 11. The right side surface of the second end portion 252 of the second support beam 25 abuts against or is adjacent to the left side surface of the second mounting portion 12, and the left side surface of the second limiting portion 52 abuts against or is adjacent to the right side surface of the second mounting portion 12. In this way, the installation rod 61, the half beam 2 and the trailing arm 3 can be further prevented from moving along the first direction, so that the structure of the independent suspension 100 is more reasonable and stable.

[0054] like Figure 4 and Figure 5 As shown, the half beam 2 includes a beam body 23, a first support beam 24 and a second support beam 25, and the longitudinal arm 3 is connected to the beam body 23. The first end 241 of the first support beam 24 is connected to the beam body 23, and the second end 242 of the first support beam 24 is rotatably disposed on the first mounting portion 11, and the rotation axis of the second end 242 of the first support beam 24 extends along the first direction.

[0055] The first end 251 of the second support beam 25 is connected to the beam body 23, and the second end 252 of the second support beam 25 is rotatably disposed on the second mounting portion 12. The rotation axis of the second end 252 of the second support beam 25 extends along the first direction. The rotation axis of the second end 242 of the first support beam 24 coincides with the rotation axis of the second end 252 of the second support beam 25. Since the first mounting portion 11, the second mounting portion 12, the second end 242 of the first support beam 24, and the second end 252 of the second support beam 25 are small in size in the first direction, only a small installation space is required to install on the chassis, so that the independent suspension 100 has the advantages of small installation space, easy installation, and no interference with other components.

[0056] Optionally, the beam body 23 extends along a first direction (eg Figure 5 ), or the angle between the extension direction of the beam body 23 and the first direction is less than or equal to a preset value (such as Figure 4 As shown in FIG. 1 ). The beam body 23 has a first end 231 and a second end 232 opposite to each other in the length direction thereof, that is, the beam body 23 has a first end 231 and a second end 232 opposite to each other in the first direction. The end 31 of the trailing arm 3 is connected to the first end 231 of the beam body 23, the first end 241 of the first supporting beam 24 is connected to the first end 231 of the beam body 23, and the first end 251 of the second supporting beam 25 is connected to the second end 232 of the beam body 23. In this way, the structures of the half beam 2 and the independent suspension 100 can be more reasonable.

[0057] like Figure 4 As shown, the independent suspension 100 includes two first mounting portions 11 and two second mounting portions 12, the two first mounting portions 11 are spaced apart in the first direction, and the two second mounting portions 12 are spaced apart in the first direction. The independent suspension 100 further includes a first mounting shaft 62 and a second mounting shaft 63. The first mounting shaft 62 is provided at the two first mounting portions 11, and the second end portion 242 of the first support beam 24 is sleeved on the first mounting shaft 62. The second mounting shaft 63 is provided at the two second mounting portions 12, and the second end portion 252 of the second support beam 25 is sleeved on the second mounting shaft 63.

[0058] Thus, the second end 242 of the first support beam 24 can be more stably and easily mounted on the first mounting portion 11, and the second end 252 of the second support beam 25 can be more stably and easily mounted on the second mounting portion 12. It can be understood that the first mounting axis 62 and the second mounting axis 63 both extend along the first direction.

[0059] Optionally, the first mounting shaft 62 is fixed to the two first mounting parts 11, and the second end 242 of the first support beam 24 is rotatably sleeved on the first mounting shaft 62. Alternatively, the first mounting shaft 62 is rotatably mounted on the two first mounting parts 11, and the second end 242 of the first support beam 24 is sleeved on the first mounting shaft 62.

[0060] Optionally, the second mounting shaft 63 is fixed to the two second mounting parts 12, and the second end 252 of the second support beam 25 is rotatably sleeved on the second mounting shaft 63. Alternatively, the second mounting shaft 63 is rotatably mounted on the two second mounting parts 12, and the second end 252 of the second support beam 25 is sleeved on the second mounting shaft 63.

[0061] like Figure 4 As shown, the second end 242 of the first support beam 24 is located between the two first mounting portions 11 in the first direction, and the second end 252 of the second support beam 25 is located between the two second mounting portions 12 in the first direction. This can further prevent the half beam 2 and the trailing arm 3 from moving along the first direction, thereby making the structure of the independent suspension 100 more reasonable and stable.

[0062] like Figure 4 As shown, the independent suspension 100 further includes a first limiting portion 51, a second limiting portion 52, a third limiting portion 53 and a fourth limiting portion 54. The first limiting portion 51 and the third limiting portion 53 are arranged on the first mounting shaft 62, and the two first mounting portions 11 are located between the first limiting portion 51 and the third limiting portion 53 in the first direction. The second limiting portion 52 and the fourth limiting portion 54 are arranged on the second mounting shaft 63, and the two second mounting portions 12 are located between the second limiting portion 52 and the fourth limiting portion 54 in the first direction. In this way, the first mounting shaft 62, the second mounting shaft 63, the half beam 2 and the trailing arm 3 can be further prevented from moving in the first direction, so that the structure of the independent suspension 100 is more reasonable and stable.

[0063] Optionally, the right side surface of the first limiting portion 51 abuts against or is adjacent to the left side surface of one first mounting portion 11, and the left side surface of the third limiting portion 53 abuts against or is adjacent to the right side surface of another first mounting portion 11. The right side surface of the fourth limiting portion 54 abuts against or is adjacent to the left side surface of one second mounting portion 12, and the left side surface of the second limiting portion 52 abuts against or is adjacent to the right side surface of another second mounting portion 12. In this way, the first mounting shaft 62, the second mounting shaft 63, the half beam 2 and the trailing arm 3 can be further prevented from moving in the first direction, so that the structure of the independent suspension 100 is more reasonable and stable.

[0064] like Figure 5As shown, the independent suspension 100 includes two first mounting portions 11 and one second mounting portion 12, and the two first mounting portions 11 are spaced apart in the first direction. The independent suspension 100 further includes a first mounting shaft 62 and a second mounting shaft 63. The first mounting shaft 62 is provided at the two first mounting portions 11, and the second end portion 242 of the first support beam 24 is sleeved on the first mounting shaft 62. The second mounting shaft 63 is provided at the second end portion 252 of the second support beam 25 and the second mounting portion 12, and the second mounting portion 12 is located between the second end portion 252 of the second support beam 25 and the first mounting portion 11 in the first direction.

[0065] Thus, the second end 242 of the first support beam 24 can be more stably and easily mounted on the first mounting portion 11, and the second end 252 of the second support beam 25 can be more stably and easily mounted on the second mounting portion 12. It can be understood that the first mounting axis 62 and the second mounting axis 63 both extend along the first direction.

[0066] Optionally, the first mounting shaft 62 is fixed to the two first mounting parts 11, and the second end 242 of the first support beam 24 is rotatably sleeved on the first mounting shaft 62. Alternatively, the first mounting shaft 62 is rotatably mounted on the two first mounting parts 11, and the second end 242 of the first support beam 24 is sleeved on the first mounting shaft 62.

[0067] Optionally, the second mounting shaft 63 is fixed to the second mounting portion 12, and the second end 252 of the second support beam 25 is rotatably sleeved on the second mounting shaft 63. Alternatively, the second mounting shaft 63 is rotatably disposed on the second mounting portion 12, and the second end 252 of the second support beam 25 is sleeved on the second mounting shaft 63.

[0068] like Figure 5 As shown, the second end 242 of the first support beam 24 is located between the two first mounting portions 11 in the first direction. This can further prevent the half beam 2 and the trailing arm 3 from moving along the first direction, thereby making the structure of the independent suspension 100 more reasonable and stable.

[0069] like Figure 5 As shown, the independent suspension 100 further includes a first limiting portion 51, a second limiting portion 52 and a third limiting portion 53. The first limiting portion 51 and the third limiting portion 53 are arranged on the first mounting shaft 62, and the two first mounting portions 11 are located between the first limiting portion 51 and the third limiting portion 53 in the first direction. The second limiting portion 52 is arranged on the second mounting shaft 63. The second mounting portion 12 is located between the second limiting portion 52 and the second end portion 252 of the second support beam 25 in the first direction. In this way, the first mounting shaft 62, the second mounting shaft 63, the half beam 2 and the longitudinal arm 3 can be further prevented from moving along the first direction, so that the structure of the independent suspension 100 is more reasonable and stable.

[0070] Optionally, the right side surface of the first limiting portion 51 abuts against or is adjacent to the left side surface of one first mounting portion 11, and the left side surface of the third limiting portion 53 abuts against or is adjacent to the right side surface of another first mounting portion 11. The right side surface of the second limiting portion 52 abuts against or is adjacent to the left side surface of the second mounting portion 12, and the left side surface of the second end portion 252 of the second supporting beam 25 abuts against or is adjacent to the right side surface of the second mounting portion 12. In this way, the first mounting shaft 62, the second mounting shaft 63, the half beam 2 and the trailing arm 3 can be further prevented from moving in the first direction, so that the structure of the independent suspension 100 is more reasonable and stable.

[0071] The independent suspension 100 may further include an elastic element and a shock absorber. One end (e.g., upper end) of the elastic element is connected to the lower body (e.g., chassis) of the vehicle 1000, and the other end (e.g., lower end) of the elastic element is connected to the longitudinal arm 3; one end (e.g., upper end) of the shock absorber is connected to the lower body (e.g., chassis) of the vehicle 1000, and the other end (e.g., lower end) of the shock absorber is connected to the longitudinal arm 3.

[0072] like Figure 6 As shown, the independent suspension 100 further includes a mounting rod 61, the half beam 2 is tubular, and each of the mounting rod 61 and the half beam 2 extends along a first direction. The mounting rod 61 is fixed to the first mounting portion 11 and the second mounting portion 12, and the half beam 2 is rotatably sleeved on the mounting rod 61.

[0073] Alternatively, the mounting rod 61 is rotatably disposed on the first mounting portion 11 and the second mounting portion 12, and the rotation axis of the mounting rod 61 extends along the first direction. The half beam 2 is sleeved on the mounting rod 61. This can make the structure of the independent suspension 100 simpler and more reasonable.

[0074] like Figure 6 As shown, the independent suspension 100 further includes a first limiting portion 51 and a second limiting portion 52, and the first limiting portion 51 and the second limiting portion 52 are arranged on the mounting rod 61. The first mounting portion 11 and the second mounting portion 12 are located between the first limiting portion 51 and the second limiting portion 52 in the first direction. In this way, the mounting rod 61 can be further prevented from moving along the first direction, so that the structure of the independent suspension 100 is more reasonable and stable.

[0075] Optionally, the first limiting portion 51 is located on the left side of the first mounting portion 11, and the right side surface of the first limiting portion 51 abuts against or is adjacent to the left side surface of the first mounting portion 11. The second limiting portion 52 is located on the right side of the second mounting portion 12, and the left side surface of the second limiting portion 52 abuts against or is adjacent to the right side surface of the second mounting portion 12. In this way, the mounting rod 61 can be further prevented from moving along the first direction, so that the structure of the independent suspension 100 is more reasonable and stable.

[0076] like Figure 6As shown, the half beam 2 is located between the first mounting portion 11 and the second mounting portion 12 in the first direction. This can further prevent the half beam 2 and the trailing arm 3 from moving along the first direction, thereby making the structure of the independent suspension 100 more reasonable and stable.

[0077] Optionally, the left side of the half beam 2 abuts against or is adjacent to the right side of the first mounting portion 11, and the right side of the half beam 2 abuts against or is adjacent to the left side of the second mounting portion 12. This can further prevent the half beam 2 and the trailing arm 3 from moving in the first direction, thereby making the structure of the independent suspension 100 more reasonable and stable.
