Description

Technical Field

[0001] This invention relates to the field of automotive suspension technology, specifically to a lower control arm with an adjustable ball joint mounting position. Background Technology

[0002] In a car's suspension system, the lower control arm is a crucial component. It plays a vital role in connecting the wheels to the vehicle body, significantly impacting the vehicle's handling, stability, and comfort. Typically mounted between the subframe and the wheel steering knuckle, its primary function is to transmit various forces and torques between the wheels and the vehicle body. During driving, when the wheels encounter uneven road surfaces and bounce, the lower control arm effectively transmits this vertical force to the vehicle body, ensuring the wheels follow a predetermined trajectory and maintaining the vehicle's straight-line stability. Furthermore, when the vehicle is cornering, the lower control arm works in conjunction with other suspension components to precisely control the wheel's camber and toe angles, ensuring sufficient contact area between the tire and the ground, providing good grip, and enabling the vehicle to smoothly and accurately complete steering maneuvers.

[0003] Traditional lower control arms have several drawbacks. Regarding ball joint adjustment, the ball joint design of traditional lower control arms presents significant limitations. In most cases, the ball joint is fixed. While this design might meet certain performance requirements in the early stages of vehicle manufacturing, with the diversification of the automotive market and the significant differences in suspension parameters between different models, fixed ball joints cannot flexibly adapt to these diverse suspension parameters. Furthermore, fixed ball joints struggle to achieve matching suspension geometry adjustments. In terms of wear prevention and lubrication, existing lower control arms employ extremely simplistic measures, typically involving only a thin layer of grease applied to key friction points such as the ball joint and dust cover. While this might provide some lubrication during initial vehicle use, the grease gradually depletes and deteriorates as mileage increases. The lack of an effective automatic lubrication mechanism prevents timely replenishment of grease, leading to increased friction between the ball joint and dust cover components. Prolonged friction not only generates harsh noise, affecting the driving experience, but also accelerates component wear, shortens the lower control arm's lifespan, and increases vehicle maintenance costs and downtime. Summary of the Invention

[0004] The purpose of this invention is to provide a lower control arm with an adjustable ball joint mounting position to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lower control arm with an adjustable ball joint mounting position, comprising:

[0006] The main shaft has a fixed bushing on its bottom surface and a main ball head on its top surface. The outer surface of the main ball head is covered with a dust cover. An adjustment mechanism is provided on the side surface of the main shaft. The adjustment mechanism includes an adjustment component and an anti-wear component.

One end of the small screws is provided with a fixing side rod. One side surface of the fixing side rod is connected to one side surface of the main rod body. Two fixing nuts are also engaged on the surface of the small screws. The two fixing nuts are respectively located on the two side surfaces of the side plates. The gap between the main rod body and the movable clamping rod is a central sliding groove. A sliding block is provided inside the central sliding groove. The main ball head is provided on one side surface of the sliding block. One side surface of the dust cover is also connected to one side surface of the sliding block.

[0009] Furthermore, internal secondary grooves are provided on both sides of the inner sliding groove. An adjustment knob is provided at one end of the locking side rod. A double-axis screw is provided on one side of the adjustment knob. Two meshing plates are engaged on the surface of the double-axis screw. A side plate that restricts the meshing plates is also provided inside the locking side rod. A locking block is provided on one side surface of the meshing plate. The locking block cooperates with the internal secondary groove inside the side sliding groove.

[0010] Furthermore, the upper surface of the mating plate is provided with two support rods, one side surface of each support rod is provided with a heat-conducting support rod, one side surface of each support rod is provided with an mounting block, and the inside of the rotating clamp is provided with an internal heat-conducting rod, which is connected to the heating main plate, the heat-conducting support rod, and the arc-shaped heat-conducting sheet.

[0011] Furthermore, a top storage box is provided between the two mounting blocks. The upper surface of the top storage box is fitted with a lid via a hinge. A conveying pipe is provided on the bottom surface of the top storage box. A carrying strainer is provided inside the top storage box. Two bottom heat transfer plates are provided on the bottom surface of the top storage box. The bottom surface of the bottom heat transfer plates is in contact with the upper surface of the heating main plate. Multiple heat transfer connecting rods are provided on the upper surface of the bottom heat transfer plates. The top surface of the heat transfer connecting rods is connected to the bottom surface of the carrying strainer.

[0012] Furthermore, a liquid grease receiving frame is provided at the center of the bottom surface of the top storage box, and side connecting pieces are provided on both sides of the liquid grease receiving frame. A connecting spring is provided on the bottom surface of the side connecting piece, and the bottom surface of the connecting spring is connected to the bottom surface of the top storage box. Multiple lower drain ports are opened on the side surface of the liquid grease receiving frame, and an internal isolation plate is provided inside the delivery pipe.

[0013] Furthermore, the internal partition plate divides the interior of the conveying pipe into an injection area and a heating area. The heating area is provided with multiple small heat-conducting strips, and each of the small heat-conducting strips has a side heat-conducting sheet at both ends. The side heat-conducting sheet is attached to the side surface of the heat-conducting support rod. The upper surface of the dust cover has an opening that communicates with the conveying pipe.

[0014] Furthermore, the adjustment mechanism also includes an additional component, which includes: two side plates, the two side plates being disposed on one side surface of the main rod, a connecting block being disposed between the two side plates, a rotating shaft being disposed between the two side surfaces of the connecting block and the inner side surfaces of the side plates, an additional bushing being disposed on the bottom surface of the connecting block, and a rotatable rotating pin being disposed on the upper surface of the connecting block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this solution, by setting up an adjustment component, the movable clamping rod can move flexibly relative to the main rod body through the cooperation of a small screw, a fixed nut and a movable clamping rod. With the help of the central sliding groove and the sliding block, the main ball head can slide precisely to the required position in the groove with the sliding block. The fixed nut is tightened to lock it securely, so that the position of the ball head can be flexibly adjusted according to the actual working conditions. This improves the versatility and adaptability of the lower control arm, provides more possibilities for the optimization of the vehicle suspension system, and effectively improves the vehicle's handling performance and driving stability.

[0017] 2. In this solution, an anti-wear component is installed. By rotating the adjustment knob, the dual-axis screw is rotated, allowing the locking side rod to be flexibly fixed and moved within the side sliding groove. This facilitates the inspection and replacement of internal components. Simultaneously, the heat generated by the friction of the main ball head is transferred to the top storage box via the arc-shaped heat-conducting plate and internal heat-conducting rod, melting the solid grease into a liquid state. The liquid grease is then precisely dripped into the dust cover through the liquid grease receiving frame and delivery pipe, achieving automatic lubrication. Furthermore, the internal isolation plate, small heat-conducting strip, and side heat-conducting plate ensure a suitable temperature within the delivery pipe, preventing the grease from solidifying. This effectively reduces component wear, extends the service life of the lower swing arm, and lowers maintenance costs.

[0018] 3. In this solution, by setting up additional components, two side plates are set on one side of the main rod, and the connecting block can be flexibly rotated by the rotating shaft, the angle of the additional bushing can be freely adjusted. The additional bushing adds an extra mounting point for the lower control arm, which can be used to install other related components, thus expanding the application range of the lower control arm. At the same time, the rotatable rotating pin can be locked between the two side plates after the additional bushing is rotated to a suitable angle, so as to firmly fix the position of the additional bushing and enable the lower control arm to better adapt to different vehicle models.

[0029] 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.

[0030] Example 1: Please refer to Figures 1 to 9 A lower control arm with an adjustable ball joint mounting position, comprising:

[0031] The main shaft 1 has a fixed bushing 8 on its bottom surface and a main ball head 5 on its top surface. A dust cover 13 is installed on the outer surface of the main ball head 5. An adjustment mechanism is provided on the side surface of the main shaft 1. The adjustment mechanism includes a positioning component and an anti-wear component. The positioning component includes a movable clamping rod 2 located on one side surface of the main shaft 1. Side plates 28 are provided on both sides below the movable clamping rod 2. Fixed plates 30 are provided on both sides below the main shaft 1. Small screws are provided on the side surfaces of the fixed plates 30. 31. A fixed side rod 9 is provided at one end of the small screw 31. One side surface of the fixed side rod 9 is connected to one side surface of the main rod body 1. Two fixed nuts 29 are also engaged on the surface of the small screw 31. The two fixed nuts 29 are located on the two sides of the side plate 28 respectively. The gap between the main rod body 1 and the movable clamping rod 2 is a central sliding groove 3. A sliding block 17 is provided inside the central sliding groove 3. The main ball head 5 is located on one side surface of the sliding block 17. One side surface of the dust cover 13 is also connected to the side surface of the sliding block 17.

[0032] When adjusting the installation position of the main ball head 5, the user can first loosen the two fixing nuts 29 on the small screw 31. Since one end of the small screw 31 is fixed to the fixed side rod 9, and the fixed side rod 9 is connected to the main rod body 1, the movable clamping rod 2 can move relative to the small screw 31 with the help of the side plate 28. The central sliding groove 3 between the movable clamping rod 2 and the main rod body 1 provides sliding space for the sliding block 17. The sliding block 17 connects the main ball head 5 and the dust cover 13. As the movable clamping rod 2 moves, the sliding block 17 loses its restrictive effect. At this time, the user can use the sliding block 17 to slide in the central sliding groove 3, thereby moving the main ball head 5 to the required position. After the adjustment is in place, tighten the two fixing nuts 29 so that they press tightly against both sides of the side plate 28, and fix the movable clamping rod 2 firmly on the main rod body 1, so as to achieve precise and stable adjustment of the position of the main ball head 5.

A limiting plate 10 that mates with the mating plate 25 is also fitted on the surface of the movable clamping rod 2. Two support rods 18 are provided on the upper surface of the mating plate 25. A heat-conducting support rod 37 is provided on one side surface of the support rods 18. An installation block 38 is provided on one side surface of the two support rods 18. The interior of the rotating clamp 16 is provided with... An internal heat-conducting rod 36 is connected to the heating main plate 39, the heat-conducting support rod 37, and the arc-shaped heat-conducting plate 35. A top storage box 19 is provided between the two mounting blocks 38. A box cover 27 is provided on the upper surface of the top storage box 19 via a hinge. A conveying pipe 26 is provided on the bottom surface of the top storage box 19. A carrying strainer 40 is provided inside the top storage box 19. Two bottom heat transfer plates 41 are provided on the bottom surface of the top storage box 19. The bottom surface of the bottom heat transfer plates 41 is attached to the upper surface of the heating main plate 39. Multiple heat transfer connecting rods 42 are provided on the upper surface of the bottom heat transfer plates 41. The top surface of the heat transfer connecting rods 42 is connected to the bottom surface of the carrying strainer 40. A heat transfer connecting rod 42 is provided at the center of the bottom surface of the top storage box 19. A liquid grease receiving frame 46 is provided. Side connecting pieces 47 are provided on both sides of the liquid grease receiving frame 46. A connecting spring 48 is provided on the bottom surface of the side connecting piece 47. The bottom surface of the connecting spring 48 is connected to the bottom surface of the top storage box 19. Multiple lower drain ports 49 are opened on the side surface of the liquid grease receiving frame 46. An internal isolation plate 43 is provided inside the conveying pipe 26. The internal isolation plate 43 divides the inside of the conveying pipe 26 into an injection area and a heating area. Multiple small heat-conducting strips 44 are provided inside the heating area. Side heat-conducting plates 45 are provided at both ends of the small heat-conducting strips 44. The side heat-conducting plates 45 are attached to the side surface of the heat-conducting support rod 37. An opening communicating with the conveying pipe 26 is opened on the upper surface of the dust cover 13.

[0034] During the use of the equipment, the anti-wear component achieves efficient anti-wear and lubrication through the coordinated action of multiple components. The locking side rod 12 can slide within the side sliding groove 11 of the movable clamping rod 2. When the user adjusts the adjustment component, in addition to the locking structure of the adjustment component itself, it is also necessary to remove the additional locking structure of the anti-wear component. By rotating the adjustment knob 20, the user drives the double-axis screw 22 to rotate. Because the meshing plate 23 is restricted by the side plate 21 to only move linearly, the rotation of the double-axis screw 22 causes the two meshing plates 23 to move towards or away from each other, thereby driving the locking block 24 to engage or disengage with the internal secondary groove inside the side sliding groove 11, thus realizing the locking side rod 12 in the side... The fixed and movable adjustment within the slide groove 11, and the rotating lever 16 on the movable frame 4 can drive the heat transfer outer ring 14 to rotate around the axis, thereby enabling the inspection and replacement of the inner main ball head 5 and dust cover 13 after long-term use. During normal use, if the grease in the dust cover 13 is consumed excessively after long-term use, the main ball head 5 will generate heat when rubbing against the inside of the dust cover 13. The heat generated will be transferred to the arc-shaped heat-conducting plate 35 on the heat transfer outer ring 14, and then transferred to the heat-conducting support rod 37, the arc-shaped heat-conducting plate 35, and the heating main plate 39 through the internal heat-conducting rod 36. This is because the top storage box 19 is pre-filled with... Solid grease is placed in a support tray 40 within the top storage box 19. The bottom heat transfer plate 41 transfers heat from the main heating plate 39 to the solid grease on the support tray 40 via the heat transfer connecting rod 42, causing it to melt from the bottom surface into liquid grease. Once formed, the liquid grease flows through the holes in the support tray 40 to the bottom of the top storage box 19, where it is finally collected by the liquid grease receiving frame 46. The liquid grease receiving frame 46 is held in a certain position by the connecting spring 48. When a certain amount of liquid grease accumulates inside, the liquid grease receiving frame 46 presses against the connecting spring 48 to descend, allowing the liquid grease to flow freely. After the grease carrier frame 46 descends into the interior of the delivery pipe 26, its side surface is no longer obstructed, and the liquid grease drips through the lower drain 49 into the interior of the dust cover 13 via the delivery pipe 26, thereby filling the interior of the dust cover 13. The internal partition plate 43 inside the delivery pipe 26 separates the filling area from the heating area. The small heat-conducting strip 44 and the side heat-conducting plate 45 transfer the heat inside the dust cover 13 through the internal heat-conducting rod 36, thereby ensuring that the temperature inside the delivery pipe 26 is maintained at a suitable temperature, ensuring that the liquid grease maintains normal flow during the delivery process and does not solidify, effectively extending the service life of the lower swing arm and reducing maintenance costs.

[0035] The adjustment mechanism also includes an additional component, which includes: two side plates 6, which are disposed on one side surface of the main rod 1, a connecting block 32 between the two side plates 6, a rotating shaft 33 between the two side surfaces of the connecting block 32 and the inner side surface of the side plate 6, an additional bushing 7 on the bottom surface of the connecting block 32, and a rotatable rotating pin 34 on the upper surface of the connecting block 32.

[0036] The additional components provide an extra mounting interface for the lower control arm, allowing the equipment to be adapted to more different vehicle models. The two side plates 6 are fixed to one side of the main rod 1. The connecting block 32 is connected to the side plates 6 through the rotating shaft 33, allowing the connecting block 32 to rotate flexibly around the rotating shaft 33. The additional bushing 7 is set on the bottom surface of the connecting block 32 and can be used to install other related components, increasing the mounting points of the lower control arm. When it is necessary to adjust the angle of the additional bushing 7 according to the actual installation situation, simply rotate the connecting block 32. At the same time, the rotatable rotating pin 34 set on the upper surface of the connecting block 32 can be rotated to a suitable angle and then rotated by the user to lock it between the two side plates 6, thereby fixing the position of the additional bushing 7.

[0037] The working principle of this invention is:

[0038] This solution mainly consists of a main rod body 1, an adjustment mechanism, and additional components. It features flexible adjustment of the position of the main ball head 5, efficient anti-wear lubrication, and compatibility with various vehicle models. The main ball head 5 is installed on one side of the sliding block 17. The sliding block 17 is located in the central sliding groove 3 formed by the main rod body 1 and the movable clamping rod 2. When the position of the main ball head 5 needs to be adjusted, the user needs to loosen the two fixing nuts 29 on the small screw 31. Since one end of the small screw 31 is fixed on the fixed side rod 9 and the fixed side rod 9 is connected to the main rod body 1, the movable clamping rod 2 can move relative to the small screw 31 with the help of the side plate 28. At this time, the restriction of the central sliding groove 3 on the sliding block 17 is weakened, pushing the sliding block 17 to slide in the central sliding groove 3, driving the main ball head 5 to the required position. After the adjustment is in place, tighten the two fixing nuts 29 to press the two sides of the side plate 28 tightly, and fix the movable clamping rod 2 firmly on the main rod body 1, so as to achieve precise and stable adjustment of the position of the main ball head 5.

[0039] The anti-wear component achieves efficient anti-wear and lubrication through the collaboration of multiple components. The locking side rod 12 can slide in the side sliding groove 11 of the movable clamping rod 2. Rotating the adjustment knob 20 drives the double-axis screw 22 to rotate. Because the meshing plate 23 is restricted by the side plate 21 to only move in a straight line, the rotation of the double-axis screw 22 causes the two meshing plates 23 to move towards or away from each other, driving the locking block 24 to engage or disengage with the sub-groove inside the side sliding groove 11, thereby realizing the fixing and movement adjustment of the locking side rod 12.

[0040] Heat is generated by the friction between the main ball head 5 and the dust cover 13, and is transferred to the arc-shaped heat-conducting plate 35 of the heat transfer outer ring 14. It is then transferred to the heat-conducting support rod 37 and the heating main plate 39 via the internal heat-conducting rod 36. Solid grease is pre-filled in the top storage box 19. The bottom heat transfer plate 41 transfers heat to the solid grease via the heat transfer connecting rod 42 to melt it. The liquid grease flows to the bottom of the top storage box 19 and is collected by the liquid grease receiving frame 46. When the liquid grease accumulates to a certain amount, it compresses the connecting spring 48 to descend and drips through the lower drain 49 into the dust cover 13 via the conveying pipe 26, thus filling the grease. The internal isolation plate 43 in the conveying pipe 26 separates the injection area from the heating area. The small heat-conducting strip 44 and the side heat-conducting plate 45 ensure that the temperature inside the conveying pipe 26 is suitable and prevent the liquid grease from solidifying.

[0041] The additional components enable the equipment to be adapted to more different vehicle models. The two side plates 6 are fixed to one side of the main rod 1. The connecting block 32 is connected to the side plates 6 through the rotating shaft 33 and can rotate flexibly around the rotating shaft 33. The additional bushing 7 is set on the bottom surface of the connecting block 32 and is used to install other related components and increase the mounting point of the lower swing arm. When adjusting the angle of the additional bushing 7 according to the actual installation situation, the connecting block 32 can be rotated. The rotating pin 34 on the upper surface of the connecting block 32 can be rotated and locked between the two side plates 6 after being rotated to a suitable angle, thus fixing the position of the additional bushing 7.

[0042] 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.
