Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a vehicle suspension control arm structure with adjustable stiffness. Background Technology

[0002] In a vehicle's suspension system, the control arm is a key component connecting the wheels and the vehicle body, and its performance directly affects the vehicle's handling stability, comfort, and safety.

[0003] Traditionally, the ball joint connector at the end of a control arm is typically a non-removable integral structure with the control arm body or is assembled by pressure. When the ball joint wears down due to long-term use, the clearance increases, or it becomes stuck due to mud and sand intrusion, maintenance and replacement become extremely inconvenient. Usually, the entire control arm assembly needs to be replaced, which is not only complex and time-consuming but also results in significant material waste and increased maintenance costs. Therefore, this invention provides an adjustable stiffness vehicle suspension control arm structure to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a vehicle suspension control arm structure with adjustable stiffness to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adjustable stiffness vehicle suspension control arm structure includes a control arm frame, with a rubber sleeve and a locking component installed at both ends of the control arm frame. A ball head is movably installed on the locking component. A reinforcing groove is formed on the side wall of the control arm frame, and connecting holes are formed through the interior of the reinforcing groove at intervals. The locking component includes two sets of clamping plates, and the ball head is installed in the two sets of clamping plates. Inserts and fasteners are installed on the two sets of clamping plates, and one end of the fastener is fixedly installed on the control arm frame. The inserts and fasteners are movably connected to each other. A bolt assembly is installed on the end of the two sets of clamping plates away from the control arm frame.

[0007] As a further embodiment of the present invention, the insert includes a connecting groove, which is formed on the side wall of two sets of clamping plates near the swing arm frame, and the connecting grooves on the two sets of clamping plates at one end are interconnected. A connecting rod is movably installed on the side wall of one set of clamping plates, and a thread is provided on the side wall of one end of the connecting rod. A push ring is installed on the side wall of the connecting rod away from the threaded end. The fastener is installed in the two sets of connecting grooves, and the push ring is movably installed on the fastener.

[0008] As a further embodiment of the present invention, the fastener includes a clamping block and a clamping plate. There are two sets of clamping blocks, and the two sets of clamping blocks are respectively installed in the connecting grooves of the two sets of clamping plates. The clamping blocks are "L" shaped blocks, wherein the clamping block near the threaded end of the connecting rod is fixedly installed in the connecting groove, and the clamping block away from the threaded end of the connecting rod is movably installed in the connecting groove. The two sets of clamping blocks are provided with movable grooves corresponding to the positions of the connecting rod.

[0009] As a further embodiment of the present invention, a clearance groove is provided inside one of the clamping plates.

[0010] As a further embodiment of the present invention, a pushing groove is provided on the inner wall of the clamping block on one side of the clearance groove, and the pushing ring is snapped into the pushing groove.

[0011] As a further embodiment of the present invention, the card plate is fixedly installed on the side wall of the swing arm frame near the two sets of clamping plates, and the inside of the card plate is provided with a card slot that penetrates the side wall of the card plate.

[0012] As a further embodiment of the present invention, a liquid groove is provided inside the clamping plate, and the liquid groove penetrates the inner side wall of the clamping plate and communicates with the inner ring position of the clamping plate. An injection hole is installed on the outer wall of the clamping plate, and the output end of the injection hole is communicated with the inside of the liquid groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. When the structure of the present invention is in use, the modular assembly structure consisting of two sets of clamping plates, inserts and fasteners allows for quick replacement or repair when the ball head is damaged or needs to be replaced, without replacing the entire swing arm assembly. Only the bolt assembly and connecting rod need to be disassembled to separate the clamping plate from the ball head, which greatly simplifies the maintenance process and reduces maintenance time and cost.

[0015] 2. When using the structure of the present invention, by setting a liquid tank inside the clamp plate that communicates with the injection hole, the user can directly inject lubricant or cleaning fluid into the joint between the ball head and the clamp plate. This allows for the effective removal of impurities such as mud and sand and lubrication of the ball head during continuous disassembly of the assembly, significantly extending the service life of the ball head and improving the maintenance convenience and overall reliability of the swing arm.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-3 In this embodiment of the invention, the adjustable stiffness vehicle suspension control arm structure includes a control arm frame 1. Rubber sleeves 2 and mounting brackets are respectively installed at both ends of the control arm frame 1. A ball joint 6 is movably installed on the mounting bracket. A reinforcing groove 3 is formed on the side wall of the control arm frame 1. Connecting holes 4 are formed through and spaced within the reinforcing groove 3. The reinforcing groove 3 and connecting holes 4 are used to install replaceable reinforcing plates or reinforcing ribs. By selecting reinforcing parts of different stiffness materials or adjusting the installation position, the stiffness of the control arm can be adjusted. The mounting bracket includes two sets of clamps. The plate 5 and the two sets of clamping plates 5 can be assembled and separated. The ball head 6 can be installed in the two sets of assembled clamping plates 5. The two sets of clamping plates 5 are equipped with inserts and fasteners. One end of the fastener is fixedly installed on the swing arm frame 1. The inserts and fasteners are movably connected to each other. By adjusting the inserts, the fasteners can be adjusted accordingly, so that the two sets of clamping plates 5 can be installed on the swing arm frame 1. The ends of the two sets of clamping plates 5 away from the swing arm frame 1 are equipped with bolt assemblies 7, which fix the two sets of clamping plates 5.

[0022] The insert includes a connecting groove 10, which is formed on the side wall of two sets of clamping plates 5 near the swing arm frame 1. The connecting grooves 10 on the two sets of clamping plates 5 are connected to each other at one end. A connecting rod 8 is movably installed on the side wall of one set of clamping plates 5. The end of the connecting rod 8 near the clamping plate 5 extends into the connecting groove 10 on the two sets of clamping plates 5 and slides through the side wall of the other set of clamping plates 5 to the other end. The connecting rod 8 can move within the connecting groove 10. A thread is provided on the side wall of one end of the connecting rod 8. A push ring 12 is installed on the side wall of the connecting rod 8 away from the threaded end. The fastener is installed in the two sets of connecting grooves 10, and the push ring 12 is movably installed on the fastener. The movement of the connecting rod 8 can drive the push ring 12 to move, thereby driving the fastener to perform fastening installation.

[0023] The fastener includes clamping blocks 11 and clamping plates 14. There are two sets of clamping blocks 11, each installed in a connecting groove 10 on one of the two clamping plates 5. Each clamping block 11 is L-shaped. The clamping block 11 near the threaded end of the connecting rod 8 is fixedly installed in the connecting groove 10, while the clamping block 11 away from the threaded end of the connecting rod 8 is movably installed in the connecting groove 10. The clamping blocks 11 can be adjusted within the connecting groove 10. Each set of clamping blocks 11 has a movable groove 17 corresponding to the position of the connecting rod 8. The inner diameter of the movable groove 17 matches the outer diameter of the connecting rod 8. The connecting rod 8 is inserted into the movable slot 17. One set of clamping plates 5 has a clearance slot 13 inside. The clearance slot 13 corresponds to the clamping block 11 that can move in the connecting slot 10. A pushing slot 18 is provided on the inner wall of the clamping block 11 on the side corresponding to the clearance slot 13. The pushing slot 18 is located in the movable slot 17, and the inner diameter of the pushing slot 18 is adapted to the outer diameter of the pushing ring 12. The pushing ring 12 is snapped into the pushing slot 18. Through the pushing ring 12 and the pushing slot 18, the connecting rod 8 can drive the clamping block 11 to move and adjust in the clearance slot 13.

[0024] The clamping plate 14 is fixedly installed on the side wall of the swing arm frame 1 near the two sets of clamping plates 5. The clamping plate 14 is a "T" shaped block. The "T" shaped end of the clamping plate 14 corresponds to the "L" end of the clamping block 11 on the two sets of clamping plates 5. The clamping plate 14 has a clamping groove 15 inside. The clamping groove 15 penetrates the side wall of the clamping plate 14. The clamping plate 14 can be clamped onto the side wall of the connecting rod 8 in the two sets of connecting grooves 10 through the penetrating end of the clamping groove 15.

[0025] By adjusting the connecting rod 8, one set of clamping blocks 11 moves within the clearance groove 13, thereby widening the distance between the two sets of clamping blocks 11. At this time, the two sets of clamping plates 5 are clamped into the clamping plate 14 on the swing arm frame 1 through the distance between the two sets of clamping blocks 11, so that the clamping plate 14 is snapped onto the connecting rod 8. Then, by adjusting the connecting rod 8 in the opposite direction, the two sets of clamping blocks 11 move closer to each other, and together with the clamping plate 14, the connecting rod 8 is clamped and fixed. At this time, the threaded end of the connecting rod 8 will protrude from the clamping plate 5, and the connecting rod 8 can be fixed by installing the appropriate nut.

[0026] It should be noted that the "T"-shaped end of the clamping plate 14 and the "L"-shaped ends of the two sets of clamping blocks 11 prevent the clamping plate 14 and the clamping blocks 11 from rotating within the connecting groove 10 of the two sets of clamping plates 5. Therefore, after installation, the two sets of clamping plates 5 will not rotate on the swing arm frame 1.

[0027] The clamping plate 5 has a liquid groove 16 inside, and the liquid groove 16 penetrates the inner side wall of the clamping plate 5 and is connected to the inner ring of the clamping plate 5. The outer wall of the clamping plate 5 is equipped with a liquid injection hole 9, and the output end of the liquid injection hole 9 is connected to the inside of the liquid groove 16. Lubricating fluid or cleaning fluid can be injected into the liquid groove 16 through the liquid injection hole 9, so that the lubricating fluid or cleaning fluid will lubricate or clean the ball head 6 on the inner ring of the clamping plate 5, which can effectively improve the maintenance effect of the swing arm.

[0028] The working principle of this invention is:

[0029] When using this invention, if the ball head 6 is damaged or malfunctions and cannot be used normally, the swing arm 1 is removed from the suspension and placed in a convenient operating position such as a workbench. The condition of the ball head 6 is observed and selectively repaired. If there is a blockage, cleaning fluid is injected into the injection hole 9 to clear the blockage between the ball head 6 and the clamping plate 5. After clearing, lubricating fluid is injected into the injection hole 9 to complete the repair. If the blockage is more serious or the ball head 6 is damaged, the nuts on the bolt assembly 7 and the connecting rod 8 are removed to separate the two sets of clamping plates 5. At this time, depending on the damage, the clamping plates 5 and the ball head 6 can be replaced or repaired. After the repair is completed, the intact (or new) clamping plates 5 and the ball head 6 are installed. The connecting rod 8 is adjusted so that the two sets of clamping plates 5 are assembled and installed on the swing arm 1 through the clamping block 11 and the clamping plate 14. The nuts on the bolt assembly 7 and the connecting rod 8 are then installed to complete the maintenance work.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
