Description

Technical Field

[0001] This utility model relates to a vehicle suspension system; in particular, it reveals an innovative structural form of an adjustable positioning structure for the control arm ball joint of a vehicle suspension system. Background Technology

[0002] The control arm in a vehicle suspension system primarily connects the wheels to the chassis and controls the position and angle of the wheels as they move up and down. As a car tire moves, it bounces up and down due to road undulations. The control arm, much like a joint in a human arm, allows the tire to move smoothly up and down while ensuring it remains in the correct position without wobbling.

[0003] The control arm mainly consists of the control arm body (usually A-shaped), ball joint, and bushing.

[0004] In order to achieve more precise adjustment of vehicle tire alignment parameters, the industry has developed some ball joint adjustment technologies to achieve precise adjustment of wheel camber, correct tire wear, or cooperate with suspension modification.

[0005] However, looking at the currently available well-known ball joint adjustable positioning structures, they generally use a combination of through holes, bolts, and nuts for locking. Practical experience has shown that this well-known structure is prone to insufficient locking force, leading to slippage. If the screws are not tightened, or loosen due to prolonged vibration, the positioning may shift, affecting driving stability and safety. Furthermore, under aggressive driving or high stress, the screws and nuts may slip due to force, causing changes in positioning parameters. This is indeed an important technical issue that deserves the attention and breakthroughs of the relevant industry. Utility Model Content

[0006] The main objective of this utility model is to provide an adjustable positioning structure for the control arm ball joint of a vehicle suspension system. The technical problem it aims to solve is to explore and innovate a new type of control arm ball joint adjustment positioning structure for a vehicle suspension system that is more ideal and practical.

[0007] Based on the aforementioned objectives, the purpose of this utility model is achieved as follows:

[0008] The adjustable positioning structure of the control arm ball joint of the vehicle suspension system includes: a control arm body, comprising two projecting arms extending to opposite sides, and a mounting section between the two projecting arms, the ends of the two projecting arms forming sleeve portions, the sleeve portions defining the X-axis at intervals, and the mounting section defining the Y-axis, such that the Y-axis is orthogonal to the X-axis, and the mounting section includes a front and a back; an elongated hole, formed in the mounting section of the control arm body and extending through the front and back, the elongated hole including two elongated ends, with the elongated ends corresponding to the Y-axis; and a ball joint, including a seat and a universal kingpin connector. The assembly includes a seat portion comprising a relatively distant assembly end and a protruding end. The threaded component protrudes from the assembly end, and the universal kingpin is pivotally assembled to the protruding end, allowing the threaded component to pass through an elongated hole and be locked in place by a nut on the back of the mounting section. A toothed engagement unit includes a toothed block and an engagement pad, wherein the toothed block is integrally formed around the elongated hole on the back of the mounting section of the control arm body, and the engagement pad includes a toothed abutment surface, a pressure surface, and a through hole. The engagement pad is assembled to the threaded component through the through hole, allowing the toothed abutment surface to engage with the toothed block, while the pressure surface is pressed against by the nut.

[0009] The outstanding and beneficial technical effects of this utility model compared with the prior art are: it can achieve a significant increase in locking force with simple components, and achieve practical progress and better industrial utilization benefits in effectively improving the robustness and durability of the control arm ball head adjustment and positioning structure.

[0010] Another objective of this invention is achieved through a technical feature that allows for a Y-axis misalignment between the universal kingpin connector of the ball head and the screw-in component. This enables the ball head to change the X-axis position of the universal kingpin connector by rotation before the adjustment is locked, thereby achieving the advantages and practical advancements of multi-adjustment to meet diverse usage needs.

[0011] Another objective of this utility model is to further improve the design by having multiple elongated holes spaced apart, with the ball head seat forming two lugs, each lug having a through hole aligned with the elongated holes, so that the screw connection is composed of two locking bolts, which pass through the aligned through holes and elongated holes and are locked in place by a nut.

[0012] Another objective of this invention is to increase the versatility of ball head adjustment by making the perforations of each lug elongated along the X-axis, so that the ball head seat has a displacement adjustment function along the X-axis before positioning. Attached Figure Description

[0023] Please see Figures 1 to 5 The diagram shows a preferred embodiment of the adjustable positioning structure of the control arm ball joint of the vehicle suspension system of this utility model. However, these embodiments are for illustrative purposes only and are not limited to this structure in the patent application.

[0024] The adjustable positioning structure of the control arm ball joint of the vehicle suspension system includes the following components: a control arm body 10, including two protruding arms 11 extending to opposite sides, and a mounting section 12 between the two protruding arms 11. The ends of the two protruding arms 11 form two sleeve portions 13, which define an X-axis at intervals. The mounting section 12 defines a Y-axis, making the Y-axis orthogonal to the X-axis. The mounting section 12 includes a front side 121 and a back side 122. An elongated hole 20 is formed in the mounting section 12 of the control arm body 10 and extends through the front side 121 and the back side 122. The elongated hole 20 includes two elongated ends 21, which correspond to the Y-axis. A ball joint 30 includes a seat 31, a universal kingpin connector 32, and a screw connection component 33, wherein the seat... 31 includes a set of relatively distant connecting ends 312 and a protruding end 314. A threaded component 33 protrudes from the connecting end 312, and a universal kingpin connector 32 is pivotally connected to the protruding end 314. The threaded component 33 passes through the elongated hole 20 and is locked in place on the back side 122 of the mounting section 12 by a nut 40. A toothed engagement unit 50 includes a toothed block 51 and an engagement pad 52. The toothed block 51 is integrally formed around the elongated hole 20 on the back side 122 of the mounting section 12 of the control arm body 10. The engagement pad 52 includes a toothed abutment surface 521, a pressure surface 522, and a through hole 523. The engagement pad 52 is connected to the threaded component 33 through the through hole 523, and the toothed abutment surface 521 is engaged with the toothed block 51. The pressure surface 522 is pressed against by the nut 40.

[0025] Therefore, when the nut 40 is loosened, the toothed section 51 and the engaging washer 52 are disengaged and released (as shown in the image). Figure 6 As shown), this allows the screw-in component 33 to be adjusted along the Y-axis (as indicated by arrow L1); conversely, when the nut 40 is tightened (as shown...), the screw-in component 33 can be adjusted along the Y-axis (as indicated by arrow L1); Figure 5 As shown in the figure, the toothed block 51 and the meshing pad 52 are engaged, thereby making the screwed part 33 achieve a tight fixed position.

[0026] like Figures 1 to 5 As shown, in this example, the elongated hole 20 is arranged in a single quantity, and the screw-in component 33 is a single stud protruding from the assembly end 312. The screw-in component 33 extends through the elongated hole 20 and is locked in place by a nut 40 on the back side 122 of the mounting section 12.

[0027] like Figure 1 and Figure 5 As shown, in this example, the universal kingpin connector 32 of the ball head 30 and the screw connection component 33 have a Y-axis misalignment relationship (e.g. Figure 5(As shown in H). The advantage of the configuration shown in this example is that, before the ball joint 30 is locked, the position of the universal kingpin joint 32 corresponding to the X-axis can be changed by rotation, thereby achieving the advantage of multiple adjustments to meet multiple usage needs.

[0028] like Figures 8 to 10 As shown, in this example, the elongated holes 20 are arranged in a plurality of spaced configurations. The seat 31 of the ball head 30 is fitted with two lugs 34, each lug 34 having a through hole 35 that aligns with each elongated hole 20. The threaded component 33B is composed of two locking bolts 60, which pass through the aligning through holes 35 and elongated holes 20 and are locked in place by nuts 40. (Note: In this example, two locking bolts 60 replace the aforementioned single threaded component 33, representing a simplified substitution embodiment of the equivalent component.)

[0029] Furthermore, the perforations 35 of each ear piece 34 are elongated along the X-axis, so that the ball head 30 seat 31 has the function of displacement adjustment along the X-axis before positioning, thereby increasing the versatility of ball head 30 adjustment.

[0030] Based on the above-described structural composition and technical features, the adjustable positioning structure of the control arm ball joint of the vehicle suspension system disclosed in this utility model, when actually installed on the vehicle suspension system 70, is as follows: Figure 7 As shown, the universal kingpin connector 32 of its ball joint 30 is used to assemble with the wheel bracket 71 of the vehicle suspension system 70. Utilizing the adjustable positioning structure of the control arm ball joint of this invention as described above, the tire positioning parameters of the vehicle can be precisely adjusted, thereby achieving precise adjustment of wheel camber, correction of tire wear, or modification of the suspension. Furthermore, this invention incorporates a toothed engagement unit 50, which, when the nut 40 is loosened, disengages the toothed block 51 from the engagement pad 52 (e.g., ...). Figure 6 As shown), this allows the screw-in component 33 to be adjusted along the Y-axis (as indicated by arrow L1); conversely, when the nut 40 is tightened (as shown...), the screw-in component 33 can be adjusted along the Y-axis (as indicated by arrow L1); Figure 5 As shown), the toothed block 51 and the meshing pad 52 are engaged, thereby making the screwed part 33 achieve a tight and fixed position, effectively preventing the problem of loosening and displacement after adjustment; in this way, the locking force can be greatly improved with simple components, achieving the advantages and practical progress of effectively improving the robustness and durability of the control arm ball head adjustment and positioning structure.
