Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically to automotive thrust rod rubber sleeves. Background Technology

[0002] The automotive thrust bar is an important component of the suspension system, also known as a "thrust bar" or "lateral stabilizer bar". It is mainly used to connect the axle and the frame, restricting the lateral displacement of the axle relative to the frame, while allowing the axle to move normally in the vertical direction.

[0003] Currently, the design of automotive thrust rod bushings is "iron-clad rubber". During the movement of the car, the bushing is subjected to forces from various angles. The current structure accelerates the wear of the bushing, resulting in a short service life. Therefore, this utility model provides an automotive thrust rod bushing to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a rubber sleeve for automotive thrust rods to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automotive thrust rod bushing includes an outer sleeve, a middle sleeve, and an inner sleeve. The middle sleeve is installed inside the outer sleeve, and the inner sleeve is rotatably installed inside the middle sleeve. The outer sleeve includes an outer sheet metal layer, the middle sleeve includes a clamp, and the inner sleeve includes a core sleeve. The clamp is fixedly installed inside the outer sheet metal layer, and the core sleeve is rotatably installed inside the clamp.

[0007] As a further embodiment of this utility model, the middle kit also includes an inner support tube, which is embedded inside the jacket.

[0008] As a further embodiment of this utility model, the outer sheet metal includes an outer rubber ring and an outer sleeve block, wherein the outer sleeve block is installed around the outer sidewall of the outer rubber ring at intervals.

[0009] As a further embodiment of this utility model, the core sleeve includes an upper closing block, an inner sleeve, a bottom fastener, and a magnetic fastener. The upper closing block is positioned above the outer rubber ring, and the inner sleeve is fixedly installed at the bottom of the upper closing block. The bottom fastener is installed on the inner bottom of the outer rubber ring, and the magnetic fastener is installed on the bottom fastener, thereby connecting the bottom fastener and the inner sleeve together.

[0010] As a further embodiment of this utility model, the jacket includes a pressure strip and a pusher strip. The pressure strip is installed around the inner sidewall of the outer rubber ring at intervals above the position, and the pressure strip is an inclined trapezoidal strip. The pusher strip is fixedly installed around the outer sidewall of the inner sleeve at intervals above the position.

[0011] As a further embodiment of this utility model, the bottom fastener includes a lower closing block, a main locking strip, an auxiliary locking strip, a locking block, and a locking groove. The lower closing block is located below the outer rubber ring. The main locking strip is installed around the lower inner side wall of the outer rubber ring at intervals. The auxiliary locking strip is installed around the top wall of the lower closing block at intervals, and the main locking strip and the auxiliary locking strip are staggered. The locking blocks are installed at intervals on the side wall of the auxiliary locking strip. The locking groove is opened at intervals on the side wall of the main locking strip. The positions of the locking blocks on the auxiliary locking strip and the locking grooves on the main locking strip correspond to each other.

[0012] As a further embodiment of this utility model, the magnetic fastener includes a limiting plate, a movable groove, a locking rod, a limiting groove, and a limiting magnetic block. The limiting plate is fixedly installed below the outer side wall of the inner sleeve and is located above the lower closing block. The movable groove is spaced around the inside of the lower closing block at a position corresponding to the limiting plate. The locking rod is installed inside the movable groove, and the top end of the locking rod slides through the top wall of the lower closing block at a corresponding position. The limiting groove is spaced around the bottom wall of the lower closing block, and the position of the limiting groove corresponds to the position of the movable groove. The limiting magnetic block is fixedly installed at the top inner side of the limiting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When this utility model is used, after the rubber sleeve is fixed to the connection position, the core sleeve can rotate. The jacket is wear-resistant. The jacket wraps around the inner support tube, which can effectively resist vibration and pressure from various angles, thereby maintaining the durability and stability of the rubber sleeve. The outer iron sheet serves as the support for the whole product and is not easily deformed. This can effectively prevent the rubber sleeve from being subjected to forces from various angles during the movement of the car, which would cause wear and reduce its service life.

[0015] 2. When using this utility model, the inner sleeve is inserted into the outer sleeve and rotated. After the pressure strip and pushing strip move and press to the designated position, the bottom fastener is installed at the bottom of the outer sleeve by plugging it in. This allows the limiting plate and limiting magnetic block to attract the locking rod into the limiting groove, thereby completing the installation of the rubber sleeve. When disassembly is required, the magnet is attracted to the lower closing block, causing the locking rod to move out of the limiting groove. At this time, the inner sleeve can be rotated in the opposite direction to complete the disassembly. This allows for the effective and convenient disassembly and installation of the rubber sleeve.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figures 1-2 In this embodiment of the utility model, the automotive thrust rod bushing includes an outer sleeve, a middle sleeve, and an inner sleeve. The middle sleeve is installed inside the outer sleeve, and the inner sleeve is rotatably installed inside the middle sleeve. The outer sleeve includes an outer sheet metal 1, the middle sleeve includes a clamp 2 and an inner support tube 4, and the inner sleeve includes a core sleeve 3. The outer sheet metal 1 is made of metal and serves as a support for the entire product, making it less prone to deformation. The clamp 2 is made of wear-resistant rubber and is fixedly installed inside the outer sheet metal 1. The inner support tube 4 is inlaid inside the clamp 2 and is made of metal. The inner support tube 4 inside the clamp 2 can effectively resist vibration and pressure at various angles, thereby maintaining the durability and stability of the bushing. The core sleeve 3 is rotatably installed inside the clamp 2.

[0028] Example 2:

[0029] Please see Figures 3-7 Based on Embodiment 1, the outer sheet metal 1 includes an outer rubber ring 5 and an outer sleeve block 6. The outer rubber ring 5 is made of rubber, and the outer sleeve block 6 is installed around the outer sidewall of the outer rubber ring 5 at intervals. The length of the outer sleeve block 6 is adapted to the length of the outer rubber ring 5.

[0030] The core sleeve 3 includes an upper closing block 7, an inner sleeve 8, a screwing block 9, a bottom fastener, and a magnetic fastener. The upper closing block 7 is an annular plate and is positioned above the outer rubber ring 5. The inner sleeve 8 is fixedly installed at the bottom of the upper closing block 7. The inner sleeve 8 is tubular and its inner diameter matches that of the upper closing block 7.

[0031] The screw block 9 is fixedly installed on the top of the upper closed block 7. The screw block 9 is hexagonal. The shape of the screw block 9 makes it easier to apply force to it with tools such as wrenches, so that the screw block 9 can drive the core sleeve 3 to rotate inside the outer iron sheet 1.

[0032] The bottom fastener is installed on the inner bottom of the outer sheet metal 1. Specifically, the bottom fastener is installed on the inner bottom of the outer rubber ring 5, and the magnetic fastener is installed on the bottom fastener. The magnetic fastener connects the bottom fastener and the inner sleeve 8 to each other.

[0033] The jacket 2 includes a pressure strip 11 and a pusher strip 12. The pressure strip 11 is installed around the inner side of the outer sheet metal 1 at intervals. Specifically, the pressure strip 11 is installed around the upper part of the inner side wall of the outer rubber ring 5 at intervals. The pressure strip 11 is an inclined trapezoidal strip and is made of rubber.

[0034] The pusher strip 12 is fixedly installed around the outside of the core sleeve 3 at intervals. Specifically, the pusher strip 12 is fixedly installed around the upper part of the outer side wall of the inner sleeve 8 at intervals. The pusher strip 12 is made of rubber, and the length of the pusher strip 12 is adapted to the length of the pressure strip 11.

[0035] The spacing between two adjacent sets of push strips 12 is matched with the spacing between two adjacent sets of pressure strips 11. The push strips 12 on the outside of the inner sleeve 8 and the pressure strips 11 on the inside of the outer rubber ring 5 are misaligned. At this time, the core sleeve 3 can be smoothly inserted into the outer sheet metal 1. After the core sleeve 3 is fully inserted into the outer sheet metal 1, by rotating the core sleeve 3, the push strips 12 on the core sleeve 3 will gradually move and squeeze the pressure strips 11 through the inclined surface of the pressure strips 11. This causes the pressure strips 11 and push strips 12 to produce matching deformation and compression, thereby increasing the friction strength between the pressure strips 11 and push strips 12, restricting the movement of the inner sleeve 8 inside the outer rubber ring 5, especially the vertical movement. At the same time, the pressure deformation generated by the compression can make the outer rubber ring 5 drive the outer sleeve block 6 to fit tightly into the mounting groove on the thrust rod.

[0036] The bottom fastener includes a lower closing block 10, a main locking strip 13, an auxiliary locking strip 14, a locking block 15, and a locking groove 17. The lower closing block 10 is located below the outer rubber ring 5 and is an annular plate made of metal. The main locking strip 13 is installed around the lower inner side wall of the outer rubber ring 5 at intervals. The auxiliary locking strip 14 is installed around the top wall of the lower closing block 10 at intervals, and the main locking strip 13 and the auxiliary locking strip 14 are staggered. The lower closing block 10 drives the auxiliary locking strip 14 to insert... The auxiliary clip 14 is inserted between two adjacent sets of main clips 13 inside the outer rubber ring 5. The clip 15 is installed at intervals on the side wall of the auxiliary clip 14. The slots 17 are opened at intervals on the side wall of the main clip 13. The positions of the clip 15 on the auxiliary clip 14 and the slots 17 on the main clip 13 correspond to each other. By inserting the auxiliary clip 14 between two adjacent sets of main clips 13, the clip 15 will squeeze the side wall of the corresponding main clip 13 and gradually lock into the slot 17, thereby completing the installation of the bottom fastener.

[0037] The magnetic fastener includes a limiting plate 16, a movable groove 18, a locking rod 19, a limiting groove 20, and a limiting magnetic block 21. The limiting plate 16 is fixedly installed below the outer side wall of the inner sleeve 8 and is located above the lower closing block 10. The movable groove 18 is spaced around the lower closing block 10 and corresponds to the position of the limiting plate 16. The locking rod 19 is installed inside the movable groove 18, and the top end of the locking rod 19 slides through the top wall of the lower closing block 10 at the corresponding position. The limiting groove 20 is spaced around the bottom wall of the lower closing block 10, and the position of the limiting groove 20 corresponds to the position of the movable groove 18. The limiting magnetic block 21 is fixedly installed at the top inner side of the limiting groove 20. The limiting magnetic block 21 can attract the locking rod 19 into the limiting groove 20, thereby preventing the limiting plate 16 from rotating on the lower closing block 10, thus restricting the movement of the inner sleeve 8 inside the outer rubber ring 5, especially the horizontal rotational movement.

[0038] Example 3:

[0039] like Figure 8 As shown, based on Embodiment 2, the pressure strip 11 is an inclined stepped trapezoidal block, wherein the first step is the initial contact position. When the pressure strip 11 and the push strip 12 are worn, the push strip 12 can be adjusted and further rotated so that the push strip 12 and the second step on the pressure strip 11 can make contact, thereby effectively compensating for the gap space generated after wear, so that the rubber sleeve can continue to be used.

[0040] The working principle of this utility model is as follows:

[0041] In use, the outer sheet metal 1 is placed in the mounting groove on the thrust rod, and the core sleeve 3 is inserted into the outer sheet metal 1. By rotating the core sleeve 3, the pushing strip 12 on the inner sleeve 8 will press the pressure strip 11 on the outer rubber ring 5, thereby causing the outer rubber ring 5 to drive the outer sleeve block 6 to fit tightly against the inner wall of the thrust rod mounting groove. At the same time, the friction between the pressure strip 11 and the pushing strip 12 increases, restricting the movement of the inner sleeve 8 inside the outer rubber ring 5. At this time, the bottom fastener is installed at the bottom of the outer sheet metal 1 by plugging it in, so that the auxiliary locking strip 14 on the lower closing block 10 will be inserted between the two adjacent sets of main locking strips 13. When the bottom fastener is fully inserted at the bottom of the outer sheet metal 1, the locking rod 19 in the movable groove 18 on the lower closing block 10 will correspond to the limiting groove 20 on the limiting plate 16, thereby causing the limiting magnetic block 21 to attract the locking rod 19 into the limiting groove 20, thereby completing the further limiting of the inner sleeve 8.

[0042] When disassembly is required, a magnetic component (magnet) with a magnetic strength greater than that of the limiting magnetic block 21 is attracted to the bottom of the lower closing block 10. The magnetic force of the magnetic component attracts the locking rod 19 into the movable groove 18, thereby no longer restricting the horizontal rotation of the inner sleeve 8. At this time, by rotating the screwing block 9, the screwing block 9 drives the inner sleeve 8 to rotate in the opposite direction, thereby causing the pushing strip 12 on the inner sleeve 8 and the pressure strip 11 on the outer rubber ring 5 to separate. At this time, the core sleeve 3 can be removed. At the same time, the outer rubber ring 5 is no longer squeezed, which will create a gap between the outer sleeve block 6 and the inner wall of the thrust rod mounting groove, thereby enabling the rubber sleeve to be removed effectively and quickly.

[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
