[0031] Reference below Figure 1-Figure 5 The axle mounting assembly 100 according to the embodiment of the utility model is described. By setting the connecting component 3, the connection between the axle 1 and the X-type thrust rod 2 can be realized, and the possibility of hole deviation problem when the axle 1 and the X-type thrust rod 2 are connected can be reduced, thereby reducing the difficulty of assembly.

[0032] like Figure 1 As shown, an axle mounting assembly 100 according to an embodiment of the utility model includes: an axle 1, an X-shaped thrust rod 2 and a connecting assembly 3.

[0033] Among them, the axle 1 is used to transmit the forces and moments in various directions between the frame 200 (or the load-bearing body) and the wheels, which has an important impact on the vehicle's dynamics, stability, carrying capacity and other performances; the X-type thrust rod 2 is used to connect the frame 200 and the axle 1 to transmit traction, braking force, lateral force and their corresponding reaction moments. At the same time, the X-type thrust rod 2 can also provide anti-roll moment and is an important component of the vehicle suspension.

[0034] The connecting assembly 3 includes a stud 31 and a connecting nut 32. The stud 31 includes a first threaded section 311 and a second threaded section 312. The first threaded section 311 is threadedly connected to the axle 1. The second threaded section 312 passes through the X-shaped thrust rod 2. The second threaded section 312 is threadedly connected to the connecting nut 32 on the side of the X-shaped thrust rod 2 facing away from the axle 1.

[0035] Specifically, Figure 2-Figure 5 As shown, a first thread segment 311 and a second thread segment 312 are respectively provided at both ends of the stud 31, that is, the first thread segment 311 and the second thread segment 312 are coaxially provided, wherein the first thread segment 311 is threadedly connected to the axle 1, that is, an external thread is provided on the first thread segment 311, and an internal thread is provided at a position on the axle 1 that cooperates with the first thread segment 311, and the first thread segment 311 of the stud 31 is connected to the axle 1 through the cooperation between the external thread and the internal thread.

[0036] At the same time, the second threaded section 312 passes through the X-shaped thrust rod 2, so that one end of the X-shaped thrust rod 2 can be pressed against the axle 1. The position where the second threaded section 312 passes through the X-shaped thrust rod 2 can be constructed as a through hole, and the inner diameter of the through hole of the X-shaped thrust rod 2 can be larger than the radial size of the second threaded section 312, so that the second threaded section 312 can pass through the X-shaped thrust rod 2. In addition, an external thread can be set on the second threaded section 312, and the second threaded section 312 is connected to the connecting nut 32 on the side of the X-shaped thrust rod 2 away from the axle 1 through the cooperation between the external thread and the internal thread of the connecting nut 32. The other end of the X-shaped thrust rod 2 can be pressed against the connecting nut 32, so that the X-shaped thrust rod 2 is connected to the stud 31, and the connection between the axle 1 and the X-shaped thrust rod 2 can be achieved.

[0037] It should be noted that the first thread segment 311 and the second thread segment 312 are respectively arranged at the two ends of the stud 31, and the first thread segment 311 can be arranged at any end of the stud 31, and the second thread segment 312 is arranged at the other end opposite to the first thread segment 311, and neither affects the connection of the stud 31 to the axle 1 and the X-shaped thrust rod 2, and the thread specifications of the first thread segment 311 and the second thread segment 312 can be the same or different, and can be flexibly set according to actual conditions.

[0038] Therefore, when the axle 1 and the X-type thrust rod 2 are connected, the two ends of the stud 31 are respectively constructed as the first threaded section 311 and the second threaded section 312, and the first threaded section 311 is firstly threadedly connected to the axle 1 to realize the assembly of the stud 31 and the axle 1, and then the axle 1 is slowly hoisted so that the second threaded section 312 penetrates the X-type thrust rod 2 and is connected to the connecting nut 32 on the side of the X-type thrust rod 2 away from the axle 1, so that the axle 1 and the X-type thrust rod 2 can be connected through the connecting assembly 3. In this process, it is not necessary to align the holes of the axle 1 and the X-type thrust rod 2 and then penetrate them with bolts as in the traditional design, which well avoids the situation that the holes of the axle 1 and the X-type thrust rod 2 are offset due to factors such as the accuracy of the parts themselves and assembly errors, and greatly reduces the difficulty of assembling the X-type thrust rod 2 and the axle 1.

[0039] According to the axle mounting assembly 100 of the embodiment of the utility model, by connecting the first threaded section 311 to the axle 1 and utilizing the cooperation of the second threaded section 312 and the connecting nut 32 to connect the X-shaped thrust rod 2 to the stud 31, the axle 1 and the X-shaped thrust rod 2 can be connected through the connecting component 3, and the possibility of hole deviation when connecting the axle 1 and the X-shaped thrust rod 2 can be reduced, thereby reducing the difficulty of assembly.

[0040] In some embodiments, the stud 31 further includes an intermediate polished rod section 313, which is connected between the first threaded section 311 and the second threaded section 312, and the intermediate polished rod section 313 is inserted into the X-shaped thrust rod 2. In other words, the stud 31 further includes the intermediate polished rod section 313 in addition to the first threaded section 311 and the second threaded section 312.

[0041] Specifically, the middle polished rod section 313 is arranged between the first threaded section 311 and the second threaded section 312, that is, the first threaded section 311 and the second threaded section 312 are respectively arranged at the two ends of the middle polished rod section 313 and are separated by the middle polished rod section 313, and the middle polished rod section 313 is passed through the X-shaped thrust rod 2, that is, the stud 31 can be passed through the X-shaped thrust rod 2 from the end where the second threaded section 312 is located until the middle polished rod section 313 is passed through the X-shaped thrust rod 2, and then the second threaded section 312 is connected to the connecting nut 32 on the side of the X-shaped thrust rod 2 away from the axle 1, so that the X-shaped thrust rod 2 can be connected to the stud 31.

[0042] It should be noted that when the X-shaped thrust rod 2 is connected to the stud 31, the second threaded section 312 can play a guiding role to improve the reliability of inserting the intermediate smooth rod section 313 into the X-shaped thrust rod 2, and can reduce the possibility of hole deviation when connecting the axle 1 and the X-shaped thrust rod 2, thereby reducing the difficulty of assembly.

[0043] In some embodiments, the radial size of the first thread segment 311 and the radial size of the second thread segment 312 are both smaller than the radial size of the middle polished rod segment 313. In other words, the radial size of the first thread segment 311 is smaller than the radial size of the middle polished rod segment 313, and the radial size of the second thread segment 312 is also smaller than the radial size of the middle polished rod segment 313, that is, the stud 31 is constructed as a structure with a thick middle and thin ends.

[0044] Specifically, the first threaded section 311 is used to cooperate with the internal thread of the axle 1, and the radial dimension of the first threaded section 311 is constructed to be smaller than the radial dimension of the intermediate polished rod section 313. The intermediate polished rod section 313 can be used to limit the axle 1 to avoid that the cooperation length between the stud 31 and the axle 1 is too large, thereby causing the stud 31 to be unable to connect with the connecting nut 32, resulting in the X-shaped thrust rod 2 being unable to be connected to the stud 31. At the same time, the second threaded section 312 passes through the X-shaped thrust rod 2. The middle polished rod segment 313 is passed through the X-shaped thrust rod 2, and the radial dimension of the second threaded segment 312 is constructed to be smaller than the radial dimension of the middle polished rod segment 313, so that the X-shaped thrust rod 2 can pass through the second threaded segment 312 until the middle polished rod segment 313 is passed through the X-shaped thrust rod 2, and the second threaded segment 312 can also play a guiding role to improve the reliability of the X-shaped thrust rod 2 being sleeved outside the middle polished rod segment 313, and reduce the possibility of hole deviation when the axle 1 and the X-shaped thrust rod 2 are connected.

[0045] In some embodiments, a first guide segment 314 is disposed between the first threaded segment 311 and the intermediate polished rod segment 313 , and a radial dimension of the first guide segment 314 is configured to gradually increase from an end connected to the first threaded segment 311 to an end connected to the intermediate polished rod segment 313 .

[0046] Specifically, a first guide section 314 can be provided between the first threaded section 311 and the intermediate polished rod section 313, and the radial dimension of the first guide section 314 can be set to gradually increase from the end connected to the first threaded section 311 to the end connected to the intermediate polished rod section 313, so that the radial dimension of the end of the first guide section 314 connected to the intermediate polished rod section 313 is larger than the radial dimension of the end connected to the first threaded section 311, and the first guide section 314 can be used to guide and limit the axle 1 to avoid that the connecting portion of the axle 1 on the stud 31 is too long, resulting in the stud 31 being unable to connect with the connecting nut 32.

[0047] And / or, a second guide segment 315 is provided between the second threaded segment 312 and the middle polished rod segment 313 , and a radial dimension of the second guide segment 315 is configured to gradually increase from an end connected to the second threaded segment 312 to an end connected to the middle polished rod segment 313 .

[0048] Specifically, a second guide section 315 can also be set between the second threaded section 312 and the intermediate polished rod section 313, which is conducive to the X-type thrust rod 2 moving from the position of the second threaded section 312 to the position of the intermediate polished rod section 313, so as to guide the X-type thrust rod 2 and improve the reliability of the X-type thrust rod 2 being sleeved outside the intermediate polished rod section 313. The radial dimension of the second guide section 315 is constructed to gradually increase from the end connected to the second threaded section 312 to the end connected to the intermediate polished rod section 313, so as to further guide the X-type thrust rod 2, so that the X-type thrust rod 2 can move from the second threaded section 312 along the second guide section 315 to the intermediate polished rod section 313, effectively improving the reliability of the X-type thrust rod 2 being sleeved outside the intermediate polished rod section 313.

[0049] In some embodiments, a tool-retracting groove 316 is formed at the connection between the first thread segment 311 and the first guide segment 314 and / or at the connection between the second thread segment 312 and the second guide segment 315. That is, the tool-retracting groove 316 is formed at the connection between the first thread segment 311 and the first guide segment 314, or at the connection between the second thread segment 312 and the second guide segment 315, or at the connection between the first thread segment 311 and the first guide segment 314 and at the connection between the second thread segment 312 and the second guide segment 315.

[0050] Specifically, the tool withdrawal groove 316 is used to facilitate the tool withdrawal when machining threads, and can be used to control the cutting depth. Figure 2-Figure 5 In the illustrated embodiment, a tool withdrawal groove 316 is formed at the connection between the first thread segment 311 and the first guide segment 314 and at the connection between the second thread segment 312 and the second guide segment 315. The two tool withdrawal grooves 316 can be used to control the thread lengths of the two thread segments and facilitate the withdrawal of the turning tool when processing the first thread segment 311 and the second thread segment 312.

[0051] In some embodiments, a through hole is provided on the X-shaped thrust rod 2, and the middle polished rod section 313 is inserted into the through hole of the X-shaped thrust rod 2 in a pin-hole matching manner.

[0052] Specifically, when the stud 31 is connected to the X-shaped thrust rod 2, the stud 31 can be inserted into the X-shaped thrust rod 2 from the end where the second threaded section 312 is located until the middle polished rod section 313 is inserted into the X-shaped thrust rod 2, wherein a through hole can be provided at a position on the X-shaped thrust rod 2 that matches with the stud 31, so that the second threaded section 312 can be inserted from the through hole, and the middle polished rod section 313 can be inserted into the through hole and connected to the X-shaped thrust rod 2 in a pin-hole matching manner, which can improve the X-shaped thrust rod 2 and The reliability of the cooperation of the middle bare rod section 313 is improved. At the same time, the X-shaped thrust rod 2 is fixed by the threaded cooperation between the second threaded section 312 and the connecting nut 32 to prevent the X-shaped thrust rod 2 from escaping from the stud 31 and being unable to connect with the axle 1. In addition, the first threaded section 311 of the stud 31 is connected to the axle 1, so that the axle 1 and the X-shaped thrust rod 2 can be connected by using the connecting assembly 3, and the possibility of hole deviation when connecting the axle 1 and the X-shaped thrust rod 2 can be reduced, thereby reducing the difficulty of assembly.

[0053] In some specific embodiments, the axial length of the first thread segment 311 and the axial length of the second thread segment 312 are both greater than the axial length of the middle polished rod segment 313 .

[0054] Specifically, the stud 31 includes a first threaded section 311, a second threaded section 312 and an intermediate polished rod section 313, and the first threaded section 311 and the second threaded section 312 are respectively connected to the two ends of the intermediate polished rod section 313, the first threaded section 311 is used to cooperate with the internal thread of the axle 1, and the second threaded section 312 is used to penetrate the X-shaped thrust rod 2 so that the X-shaped thrust rod 2 can cooperate with the intermediate polished rod section 313, and the axial length of the first threaded section 311 is set to be greater than the axial length of the intermediate polished rod section 313 to ensure that the connection length between the first threaded section 311 and the axle 1 is long enough, thereby ensuring the connection strength between the first threaded section 311 and the axle 1, and the axial length of the second threaded section 312 is set to be greater than the axial length of the intermediate polished rod section 313. The length is set to be greater than the axial length of the middle polished rod section 313, so that when the X-shaped thrust rod 2 is matched with the middle polished rod section 313, the X-shaped thrust rod 2 can be completely sleeved on the outside of the middle polished rod section 313, or partially sleeved on the outside of the middle polished rod section 313, and partially sleeved on the outside of the second threaded section 312, so as to avoid that the connecting nut 32 cannot be pressed against the X-shaped thrust rod 2, so that the X-shaped thrust rod 2 cannot be fixed, and the length of the second threaded section 312 extending out of the X-shaped thrust rod 2 can be long enough, thereby ensuring the connection length between the second threaded section 312 and the connecting nut 32, that is, ensuring the connection strength of the X-shaped thrust rod 2 to the stud 31, and thereby ensuring the connection strength between the axle 1 and the X-shaped thrust rod 2.

[0055] In some embodiments, the second thread segment 312 is formed with a screwing portion 317 at one end away from the first thread segment 311, and the screwing portion 317 is used to cooperate with a screwing tool. That is, the end of the second thread segment 312 facing the first thread segment 311 is connected to the middle polished rod segment 313, and the end away from the first thread segment 311 is provided with the screwing portion 317.

[0056] Specifically, the stud 31 includes a first threaded section 311 and a second threaded section 312. The first threaded section 311 is used to cooperate with the internal thread of the axle 1. A screwing portion 317 is provided at one end of the second threaded section 312 away from the first threaded section 311. The screwing portion 317 can be used to conveniently screw the first threaded section 311 into the internal thread of the axle 1 to achieve the connection between the two. When the second threaded section 312 is connected to the connecting nut 32, the stud 31 can be fixed by fixing the screwing portion 317, and then the second threaded section 312 and the connecting nut 32 are tightened by rotating the connecting nut 32, which can avoid damaging the internal thread of the axle 1. In addition, by providing the screwing portion 317, the first threaded section 311 can be screwed into the internal thread of the axle 1 by using the screwing tool and the screwing portion 317 to reduce the difficulty of operation and improve installation efficiency.

[0057] Among them, Figure 1-Figure 5 As shown, the screwing portion 317 may be constructed as an external hexagonal structure, and it should be noted that the screwing tool may be an electric tool or a pneumatic tool.

[0058] In some embodiments, the X-shaped thrust rod 2 includes a connecting arm 21, the connecting arm 21 extends above the axle 1, and the connecting arm 21 is connected to the axle 1 through at least one connecting assembly 3. In other words, the connection between the axle 1 and the X-shaped thrust rod 2 is achieved by connecting the connecting arm 21 to the axle 1.

[0059] Specifically, when the X-shaped thrust rod 2 is connected to the axle 1, the connecting arm 21 on the X-shaped thrust rod 2 can be extended above the axle 1, and the connecting arm 21 can be connected to the axle 1 in the up and down directions through the connecting component 3, so that the connection between the X-shaped thrust rod 2 and the axle 1 can be realized, and the connecting arm 21 can be connected to the axle 1 through at least one connecting component 3, that is, the axle 1 can be connected to the connecting arm 21 through one, two or more connecting components 3. As the number of connecting components 3 increases, the connection strength and connection reliability between the axle 1 and the connecting arm 21 can be improved, that is, the connection strength and connection reliability between the axle 1 and the X-shaped thrust rod 2 can be improved.

[0060] In some embodiments, there are two connecting arms 21 , and the two connecting arms 21 are spaced apart in the lateral direction, and at least one connecting component 3 is disposed on both lateral sides of each connecting arm 21 .

[0061] Specifically, two connecting arms 21 are provided in the X-shaped thrust rod 2, and the two connecting arms 21 are spaced apart in the transverse direction, that is, the two connecting arms 21 can be respectively connected to the axle 1 in the transverse direction, which can improve the connection reliability between the two, and at least one connecting component 3 is provided on both sides of each connecting arm 21 in the transverse direction, that is, the connecting arm 21 is connected to the axle 1 by at least one connecting component 3 on both sides of each connecting arm 21, which can improve the connection strength and connection reliability between the connecting arm 21 and the axle 1, and can balance the force, thereby reducing the fracture failure of the connecting component 3 due to stress concentration.

[0062] In such Figure 1 In the illustrated embodiment, a connecting component 3 is provided on both lateral sides of each connecting arm 21, that is, four connecting components 3 are provided in the axle mounting assembly 100 to connect the two connecting arms 21 with the axle 1, that is, each connecting arm 21 can be connected to the axle 1 through the connecting components 3 on both sides, respectively, which can improve the connection strength and connection reliability between the axle 1 and the X-type thrust rod 2, and can balance the forces on both sides of each connecting arm 21.

[0064] And, it should be noted that if Figure 4-Figure 5 As shown, a gasket 4 is further provided on the side of the connecting nut 32 close to the X-shaped thrust rod 2. The gasket 4 is sleeved outside the second threaded section 312 to protect the X-shaped thrust rod 2, so as to reduce the possibility of wear of the X-shaped thrust rod 2 under the action of the connecting nut 32, and to prevent the connecting nut 32 from being screwed into the X-shaped thrust rod 2, resulting in the inability to connect the X-shaped thrust rod 2 to the stud 31.
