DETAILED DESCRIPTION

[0033] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0034] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" generally refer to the upper and lower parts of the steering assembly in space when the steering assembly is in use. "Inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order or importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0035] According to a first aspect of the present disclosure, a ball pin assembly is provided, referring to Figures 1 to 6 As shown, the ball-pin assembly comprises a pin shaft 1, a ball head 3, a limiting portion 4 and an adjusting member 7, wherein the pin shaft 1 is used to be connected to the steering knuckle 2; the ball head 3 is detachably sleeved on the pin shaft 1; the ball head 3 has the above-mentioned limiting portions 4 at both opposite ends along the axial direction of the pin shaft 1, and the ball head 3 is used to be connected to the steering tie rod 5 or the swing arm 6; at least one limiting portion 4 is provided with at least one adjusting member 7 on the side axially away from the ball head 3, and the adjusting member 7 is used to be arranged between the steering knuckle 2 and the limiting portion 4 adjacent to the adjusting member 7, so as to adjust the position of the ball head 3 relative to the steering knuckle 2.

[0036] Through the above technical solution, that is, the ball pin assembly provided by the present disclosure, the ball pin assembly is detachably sleeved on the pin shaft 1 for connecting the steering knuckle 2, and the ball head 3 is provided with a limiting portion 4 at both opposite ends of the axial direction of the pin shaft 1 for limiting and fixing, so that the ball head 3 for connecting the steering tie rod 5 or the swing arm 6 can be stably connected to the pin shaft 1 and stably connected to the steering knuckle 2 through the pin shaft 1, with high reliability and simpler overall structure, which is convenient for on-site disassembly and assembly. In addition, at least one limiting portion 4 is provided with at least one adjusting member 7 on the side away from the ball head 3 along the axial direction of the pin shaft 1, and the adjusting member 7 is arranged between the steering knuckle 2 and the limiting portion 4, so that the position of the ball head 3 relative to the steering knuckle 2 can be adjusted by the adjusting member 7, that is, it can be understood that the position of the hard point (the ball center of the ball head 3) of the ball head 3 for connecting the steering tie rod 5 or the swing arm 6 can be adjusted to ensure that the whole vehicle has high maneuverability, stability and comfort, etc., and effectively improve the performance of the whole vehicle.

[0037] In some embodiments, reference Figures 3 to 6 As shown, at least one of the two limiting parts 4 is detachably sleeved on the pin shaft 1, so as to facilitate the disassembly and assembly of the ball head 3 located between the two limiting parts 4. The structure is simple and easy to operate.

[0038] For example, Figure 3As shown, the two limiting parts 4 may include a sleeve 410, and the sleeve 410 is sleeved on the pin shaft 1, that is, it can be understood that the two limiting parts 4 constructed as sleeves 410 can be detachably sleeved on the pin shaft 1, and the sleeve 410 may include a first bearing section 411 and a first stop section 412, and the ball head 3 is sleeved on the two first bearing sections 411 of the two sleeves 410, and is located between the two first stop sections 412 of the two sleeves 410. The reliability is high and by arranging the ball head 3 on the first bearing sections 411 of the two sleeves 410, when the steering rod 5 or the swing arm 6 connected to the ball head 3 pulls the ball head 3, the structural stiffness and tensile strength can be improved by the sleeve 410.

[0039] Among them, Figure 3 As shown, the two first stop sections 412 are each provided with an adjusting member 7 on one side facing away from the ball head 3. Exemplarily, the adjusting member 7 may include an annular gasket 710 sleeved on the pin shaft 1. Thus, the position of the two limit portions 4 constructed as a sleeve 410 can be adjusted by adjusting the number of annular gaskets 710 on both sides, thereby achieving position adjustment of the ball head 3 arranged on the sleeve 410, so as to achieve the purpose of changing the position of the ball head 3 relative to the steering knuckle 2, that is, to achieve adjustment of the position of the hard point (the center of the ball head 3) of the ball head 3 used to connect the steering rod 5 or the swing arm 6, so as to ensure that the whole vehicle has higher maneuverability, stability and comfort, etc., and effectively improve the performance of the whole vehicle.

[0040] It should be noted that the specific method of adjusting the number of annular gaskets 710 located on both sides can be, for example, by increasing the number of annular gaskets 710 arranged on one side and correspondingly reducing the number of annular gaskets 710 arranged on the other side, so as to achieve the purpose of changing the position of the sleeve 410 and the ball head 3 thereon relative to the steering knuckle 2.

[0041] In addition, if Figure 3 As shown, the end of the first stop section 412 adjacent to the adjusting member 7 may be provided with a first annular protrusion 413 extending radially outward, and the first annular protrusion 413 has a first stop surface 4131 for fitting against the adjusting member 7, which helps to increase the contact area and improve the stability and safety of the connection between the ball pin assembly and the steering knuckle 2.

[0042] It should be noted that the present disclosure does not specifically limit the specific structure of the two limit parts 4 configured as the sleeve 410, and those skilled in the art can design it adaptively according to actual application requirements, for example Figure 3 In the figure, it is shown that the two limiting parts 4 can be constructed as sleeves 410 with the same outer shape structure, and the limiting installation and fixation of the ball head 3 are realized by two sleeves 410 with the same outer shape structure. Alternatively, in other embodiments, as Figure 6As shown, the two limiting parts 4 can also be constructed with different external structures, for example, one of the two limiting parts 4 is constructed to include a sleeve 410, and the other limiting part 4 is constructed to include a retaining ring 431, and the sleeve 410 includes a first bearing section 411 and a first stop section 412, and the retaining ring 431 includes a second bearing section 4311 and a second stop section 4312. In this way, by setting the ball head 3 on the first bearing section 411 of the sleeve 410 and the second bearing section 4311 of the retaining ring 431, and by the first stop section 412 and the second stop section 4312 located on both sides of the ball head 3 to achieve limiting fixation, the ball head 3 located between the sleeve 410 and the retaining ring 431 can also be fixed by limiting installation. The present disclosure is not limited to this.

[0043] In addition, the above-mentioned specific embodiment in which both the two limiting parts 4 are detachably sleeved on the pin 1 is exemplary. In other embodiments, refer to Figure 4 As shown, the two limiting parts 4 may also include a first limiting part 420 and a second limiting part 430, the first limiting part 420 includes a limiting section 421 constructed as an integral part with the pin shaft 1, and the second limiting part 430 includes a retaining ring 431 sleeved on the pin shaft 1, that is, it can be understood that one of the two limiting parts 4 (for example, the first limiting part 420) can be exemplarily constructed as an integral part with the pin shaft 1, and the other limiting part 4 (for example, the second limiting part 430) can be detachably sleeved on the pin shaft 1, so as to facilitate the disassembly and assembly of the ball head 3, and the limiting section 421 and the retaining ring 431 are stopped on both sides of the ball head 3 to achieve limiting fixation, with a simple structure and high reliability.

[0044] Among them, Figure 4 As shown, an adjusting member 7 may be provided on the side of the limiting section 421 facing away from the ball head 3. For example, the adjusting member 7 may include an annular gasket 710 sleeved on the pin shaft 1. In this way, the position of the pin shaft 1 integrally constructed with the limiting section 421 can be adjusted by adjusting the number of annular gaskets 710 (for example, increasing or decreasing the number of annular gaskets 710). Then, the position of the ball head 3 arranged on the pin shaft 1 can be adjusted to achieve the purpose of changing the position of the ball head 3 relative to the steering knuckle 2, that is, to achieve the adjustment of the position of the hard point (the center of the ball head 3) of the ball head 3 used to connect the steering rod 5 or the swing arm 6, so as to ensure that the whole vehicle has higher maneuverability, stability and comfort, etc., and effectively improve the performance of the whole vehicle.

[0045] In addition, if Figure 4 As shown, the end of the limiting section 421 facing away from the ball head 3 can be provided with a second annular protrusion 422 extending radially outward, and the second annular protrusion 422 has a second stop surface 4221 that fits against the adjusting member 7, which helps to increase the contact area and improve the stability and safety of the connection between the ball pin assembly and the steering knuckle 2.

[0046] In addition, if Figure 4 As shown, the pin shaft 1 may include a shaft section 110 arranged adjacent to the limiting section 421, and a fastening section 120 connected to the shaft section 110 and away from one end of the limiting section 421, the fastening section 120 is connected to a fastener 8 (such as a locking nut), the ball head 3 is sleeved on the shaft section 110, and the retaining ring 431 is located between the ball head 3 and the fastener 8, so that the ball head 3 is limitedly installed and fixed by the limiting sections 421 and the retaining ring 431 located at the opposite ends of the ball head 3 along the axial direction of the pin shaft 1, and the ball head 3 and the retaining ring 431 can also be locked by the fastener 8 (such as a locking nut) to avoid axial movement, which is convenient for disassembly and assembly and can also improve the connection reliability.

[0047] Optionally, Figure 4 It is exemplarily shown that the outer diameter of the fastening section 120 can be smaller than the outer diameter of the shaft section 110, and the retaining ring 431 includes a second bearing section 4311 and a second stop section 4312. In this way, when the retaining ring 431 is exemplarily sleeved on the fastening section 120, the outer diameter of the second bearing section 4311 of the retaining ring 431 is the same as the outer diameter of the shaft section 110, so as to facilitate the sleeve connection of the ball head 3 on the shaft section 110 and the second bearing section 4311 and to be located between the limiting section 421 and the second stop section 4312, so as to achieve the purpose of limiting the installation and fixing of the ball head 3. The structure is simple and easy to operate.

[0048] It should be noted that the present disclosure does not specifically limit the specific arrangement number of the above-mentioned annular gaskets 710 and the size and material of each annular gasket 710. Those skilled in the art can adaptively adjust according to actual application requirements. The purpose is to ensure that the annular gasket 710 has a high structural strength and to be able to adjust the position of the ball head 3 relative to the steering knuckle 2 by increasing or decreasing the number of corresponding annular gaskets 710.

[0049] In addition, the specific embodiment in which the above-mentioned adjusting member 7 may include an annular gasket 710 sleeved on the pin shaft 1 is exemplary. In other embodiments not shown in the figure, the above-mentioned adjusting member 7 may also be constructed to, for example, include a nut arranged between the steering knuckle 2 and the limiting portion 4. The present disclosure does not specifically limit this type of deformation mode. Those skilled in the art can adaptively design it according to actual application requirements, with the purpose of being able to adjust the position of the ball head 3 relative to the steering knuckle 2.

[0050] According to a second aspect of the present disclosure, a steering assembly is provided, comprising a steering knuckle 2 and the ball pin assembly provided in the first aspect. The steering assembly can adjust the position of the ball head 3 relative to the steering knuckle 2, improve the performance of the whole vehicle, and has the advantages of simple structure and high reliability. In addition, the steering assembly also has all the beneficial effects of the ball pin assembly provided in the first aspect, which will not be repeated in this disclosure.

For example, as shown in FIG. Figure 3 As shown, the two first mounting portions 210 are formed on the steering knuckle 2 to extend outward and are arranged side by side as a first convex rib 212 and a second convex rib 213, the first convex rib 212 and the second convex rib 213 are respectively formed with the above-mentioned first mounting holes 211, the pin 1 may include a first bolt 130, the bolt head of the first bolt 130 is directly or indirectly (for example, an elastic gasket is provided between the bolt head and the first convex rib 212) abuts against the first convex rib 212, the end of the first bolt 130 opposite to the bolt head passes through the first convex rib 212, the ball head 3 provided between the first convex rib 212 and the second convex rib 213, the two limiting portions 4 and the adjusting member 7, and the second convex rib 213 and then is threadedly connected to the first nut 9, the structure is simple, easy to install and has high connection reliability.

[0052] It should be noted that when the position of the ball head 3 connected to the steering tie rod 5 relative to the steering knuckle 2 needs to be adjusted, Figure 3 As shown, the position of the two limit portions 4 constructed as a sleeve 410 can be adjusted by adjusting the number of annular gaskets 710 located on both sides, and then the position of the ball head 3 arranged on the sleeve 410 can be adjusted to achieve the purpose of changing the position of the ball head 3 relative to the steering knuckle 2. At the same time, since there is no need to adjust the position of the first bolt 130 relative to the steering knuckle 2, the position of the ball head 3 relative to the steering knuckle 2 can be adjusted by only changing the positions of the two sleeves 410 for installing the ball head 3, which occupies less space and provides a larger design space for the subsequent design of the entire vehicle.
