Description

Technical Field

[0001] This invention relates to the field of automotive shock absorber technology, specifically a shock absorber for automotive suspension, an assembly device, and an assembly method. Background Technology

[0002] Suspension shock absorbers are installed in parallel with the elastic elements in the suspension system to dampen vibrations caused by impacts, thus improving ride comfort. The most widely used type in automotive suspension systems is the telescopic shock absorber, which provides damping during both compression and extension strokes; this is called a two-way shock absorber. Newer types of shock absorbers also exist, including air-filled shock absorbers and adjustable-drag shock absorbers.

[0003] Currently, the cylindrical shock absorber mainly consists of a cylinder, a tie rod, a shock absorber spring, and a sealing cover. The existing installation method is generally to first install the shock absorber spring into the cylinder, then insert the tie rod into the cylinder and cooperate with the shock absorber spring to buffer and dampen the shock using the spring force, and finally use multiple bolts to fix the sealing cover to the cylinder.

[0004] However, the above assembly method has some shortcomings. First, whether assembling or disassembling the sealing cover, multiple bolts need to be tightened one by one, which not only makes the assembly inefficient but also inconvenient to operate. Second, using multiple bolts to fix the sealing cover and cylinder makes it difficult to ensure that each bolt is tightened to the same degree during operation. This may cause misalignment between the sealing cover and the cylinder. Since the tie rod is in sliding fit with the sealing cover and cylinder, misalignment between the sealing cover and cylinder may cause abnormal wear of the tie rod and the sealing cover and cylinder during sliding, shortening the service life of the shock absorber. Summary of the Invention

[0005] The purpose of this invention is to provide a shock absorber, assembly device, and assembly method for an automotive suspension to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A shock absorber for an automobile suspension includes a cylinder and a tie rod that slides with the cylinder, wherein a sealing cap is installed at the opening of the cylinder.

[0008] The outer wall of the pull rod is provided with a limit ring, and a shock-absorbing spring is installed inside the cylinder. The two ends of the shock-absorbing spring abut against the inner bottom of the cylinder and the bottom of the limit ring, respectively.

[0009] A connecting assembly is provided between the cylinder and the sealing cover, which enables quick assembly and disassembly of the cylinder and the sealing cover.

[0010] As a further aspect of the present invention: the connecting assembly includes a retaining ring disposed inside the cylinder and a mounting spring installed inside the cylinder with one end abutting against the top of the retaining ring;

[0011] The outer wall of the sealing cover is provided with multiple locking blocks, and the inner wall of the top of the cylinder is provided with multiple locking grooves. The other end of the mounting spring abuts against the bottom of the sealing cover, so that the multiple locking blocks are respectively located inside the multiple locking grooves. The top of the cylinder is also provided with multiple through grooves through which the multiple locking blocks can slide.

[0012] An assembly device for a shock absorber of an automobile suspension as described above includes a frame and a base plate that is vertically slidably disposed on the frame. A rotating seat is horizontally rotatably disposed on the base plate. A locking groove is provided on the inner bottom of the rotating seat. The rotating seat is used to install the cylinder.

[0013] The frame is equipped with a drive mechanism and a clamping assembly. The clamping assembly is connected to the drive mechanism and clamps and fixes the sealing cover under the action of the drive mechanism.

[0014] A lifting assembly is provided between the base plate and the frame. The lifting assembly is connected to the drive mechanism. The base plate will drive the rotary table to rise under the cooperation of the lifting assembly and the drive mechanism.

[0015] A rotating assembly is also provided between the frame and the base plate. The rotating assembly is connected to the driving mechanism, and the rotating seat will rotate under the cooperation of the rotating assembly and the driving mechanism.

[0016] As a further embodiment of the present invention: the driving mechanism includes a driving disk, a first driven disk, a second driven disk, and a third driven disk. The driving disk cooperates with the first driven disk, the second driven disk, and the third driven disk respectively to alternately drive the first driven disk, the second driven disk, and the third driven disk to rotate.

[0017] As a further embodiment of the present invention: a hollow cylinder is vertically rotatably mounted on the frame, and the active disk is disposed on the outer wall of the hollow cylinder;

[0018] The frame is equipped with a support, and a motor is vertically mounted on the support. The output end of the motor is equipped with a drive pulley, and the outer wall of the hollow cylinder is equipped with a driven pulley. The drive pulley and the driven pulley are connected by a belt.

[0019] As a further embodiment of the present invention: the clamping assembly includes a frame plate disposed on the frame body and a guide rod horizontally rotatably disposed on the frame plate. Two clamping plates are symmetrically and slidably disposed on the guide rod. A bidirectional lead screw is rotatably disposed on the frame plate. One end of each of the two clamping plates is threaded into the outer wall of the bidirectional lead screw.

[0020] The outer wall of the bidirectional lead screw is provided with a driven bevel gear, and a first rotating rod is vertically rotatably mounted on the frame. One end of the first rotating rod is connected to the first driven disc, and the other end of the first rotating rod is provided with a driving bevel gear. The driving bevel gear and the driven bevel gear mesh with each other.

[0021] As a further embodiment of the present invention: the lifting assembly includes a second rotating rod that rotates with the base plate, the bottom end of the second rotating rod being rotatably connected to the frame, and the top end of the second rotating rod being connected to the second driven plate;

[0022] The outer wall of the second rotating rod is provided with a spiral groove, and a ball is rolled and embedded inside the base plate. The ball is also embedded inside the spiral groove and slides in fit.

[0023] As a further embodiment of the present invention: the rotating assembly includes a first gear disposed on the outer wall of the rotating base and a rotating cylinder rotatably disposed on the base plate, wherein the outer wall of the rotating cylinder is provided with a second gear that meshes with the first gear.

[0024] The frame is rotatably equipped with a No. 3 rotating rod, the top of which is connected to the No. 3 driven disc, and the No. 2 gear is sleeved on the outer wall of the No. 3 rotating rod and slides in cooperation with it.

[0025] The second gear has a limiting groove inside, and the outer wall of the third rotating rod is provided with a limiting post along its length. The limiting post is located inside the limiting groove and slides with each other.

[0026] A method for assembling a shock absorber for a vehicle suspension using the assembly device described above includes the following steps:

[0027] Step 1: Install the cylinder into the inside of the rotary seat, so that the bottom of the cylinder is located in the locking groove, so that the cylinder will move synchronously with the rotary seat when it rotates and rises.

[0028] Step 2: Insert the tie rod inside the cylinder barrel so that the limiting ring abuts against the shock-absorbing spring. Then place the sealing cover on the top of the cylinder barrel, and make the multiple locking blocks correspond to the positions of the multiple through slots respectively.

[0029] Step 3: The sealing cap is clamped and fixed by the cooperation of the drive mechanism and clamping components in the assembly device.

[0030] Step 4: The lifting assembly is driven by the drive mechanism, which causes the rotary table to move the cylinder vertically upward. At the same time, multiple locking blocks on the sealing cover will pass through multiple slots and enter the cylinder, and the mounting spring will be compressed.

[0031] Step 5: The rotating component in the assembly device works in conjunction with the drive mechanism to make the cylinder rotate with the rotary table, so that the multiple slots on the top of the cylinder correspond to the multiple blocks on the sealing cover. Then, the clamping component releases the fixing of the sealing cover, and the reset force of the installation spring makes the multiple slots and multiple blocks interlock.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] The drive mechanism sequentially drives the clamping assembly, lifting assembly, and rotating assembly, enabling the sealing cover and the cylinder installed in the rotary seat to be fixedly assembled with the connecting assembly. Compared to the traditional bolt-fixed connection between the sealing cover and the cylinder, the installation method in this application is more convenient, improving assembly efficiency. Furthermore, compared to the existing bolt-fixed method, the connecting assembly method used in this application not only ensures a firm installation but also guarantees that the sealing cover and the cylinder are concentric, thereby preventing abnormal wear during the sliding of the tie rod with the sealing cover and cylinder and extending the service life of the shock absorber.

Detailed Implementation

[0047] 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.

[0048] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0049] Please see Figures 2-5 In this embodiment of the invention, a shock absorber for an automobile suspension includes a cylinder 1 and a tie rod 2 that slides with the cylinder 1, and a sealing cover 3 is installed at the opening of the cylinder 1.

[0050] The outer wall of the pull rod 2 is provided with a limit ring 4, and the inside of the cylinder 1 is equipped with a shock-absorbing spring 5. The two ends of the shock-absorbing spring 5 abut against the inner bottom of the cylinder 1 and the bottom of the limit ring 4, respectively.

[0051] A connecting assembly is provided between the cylinder 1 and the sealing cover 3, which enables quick assembly and disassembly of the cylinder 1 and the sealing cover 3.

[0052] In this embodiment, since the cylinder 1 and the tie rod 2 are in sliding engagement, and the two ends of the damping spring 5 abut against the inner bottom of the cylinder 1 and the bottom of the limiting ring 4 respectively, the damping spring 5 can buffer and decelerate the mutual sliding of the cylinder 1 and the tie rod 2.

[0053] The connecting assembly allows for quick assembly and disassembly of the sealing cover 3 and the cylinder 1, and the sealing cover 3 prevents the pull rod 2 from sliding out of the cylinder 1.

[0054] Please see Figures 2-5 The connecting assembly includes a retaining ring 6 disposed inside the cylinder 1 and a mounting spring 7 installed inside the cylinder 1 with one end abutting against the top of the retaining ring 6;

[0055] The outer wall of the sealing cover 3 is provided with a plurality of locking blocks 8, and the inner wall of the top of the cylinder 1 is provided with a plurality of locking grooves 9. The other end of the mounting spring 7 abuts against the bottom of the sealing cover 3, so that the plurality of locking blocks 8 are respectively located inside the plurality of locking grooves 9. The top of the cylinder 1 is also provided with a plurality of through grooves 10 through which the plurality of locking blocks 8 can slide.

[0056] In this embodiment, due to the presence of the mounting spring 7 and its continued compression, the sealing cover 3 will be driven by the mounting spring 7 to keep the multiple locking blocks 8 in close contact with the multiple locking slots 9, thereby connecting the sealing cover 3 to the cylinder 1.

[0057] Multiple through slots 10 provided on the top of cylinder 1 are used for multiple locking blocks 8 to slide in and out, thereby enabling the sealing cover 3 to be disassembled and assembled with cylinder 1; retaining ring 6 is used to support the installation of spring 7.

[0058] Please see Figures 2-12An assembly device for a shock absorber of an automobile suspension as described above includes a frame 11 and a base plate 12 vertically slidably disposed on the frame 11. A rotating seat 13 is horizontally rotatably disposed on the base plate 12. A locking groove 14 is provided in the inner bottom of the rotating seat 13. The rotating seat 13 is used to install the cylinder 1.

[0059] The frame 11 is provided with a drive mechanism and a clamping assembly. The clamping assembly is connected to the drive mechanism and clamps and fixes the sealing cover 3 under the action of the drive mechanism.

[0060] A lifting assembly is provided between the base plate 12 and the frame 11. The lifting assembly is connected to the driving mechanism. The base plate 12 will drive the rotating seat 13 to rise under the cooperation of the lifting assembly and the driving mechanism.

[0061] A rotating assembly is also provided between the frame 11 and the base plate 12. The rotating assembly is connected to the driving mechanism, and the rotating seat 13 will rotate under the cooperation of the rotating assembly and the driving mechanism.

[0062] In this embodiment, the driving mechanism drives the clamping component, the lifting component and the rotating component to move in sequence, so that the sealing cover 3 and the cylinder 1 installed in the rotating seat 13 can be fixedly assembled with the connecting component. Compared with the traditional connection method of fixing the sealing cover 3 and the cylinder 1 with bolts, the assembly method in this application is more convenient and can greatly improve production efficiency for batch processing and assembly.

[0063] Please see Figure 6 , Figure 7 The driving mechanism includes a driving disc 15, a first driven disc 16, a second driven disc 17, and a third driven disc 18. The driving disc 15 cooperates with the first driven disc 16, the second driven disc 17, and the third driven disc 18 to alternately drive the first driven disc 16, the second driven disc 17, and the third driven disc 18 to rotate.

[0064] In this embodiment, the drive disc 15, the first driven disc 16, the second driven disc 17, and the third driven disc 18 together form the Maltese cross movement structure. By rotating the drive disc 15, the first driven disc 16, the second driven disc 17, and the third driven disc 18 can be rotated alternately.

[0065] When the first driven disk 16 rotates, the second driven disk 17 and the third driven disk 18 will remain stationary;

[0066] When the second driven disk 17 rotates, the first driven disk 16 and the third driven disk 18 will remain stationary;

[0067] When the third driven disk 18 rotates, the first driven disk 16 and the second driven disk 17 will remain stationary.

[0068] Please see Figure 6 , Figure 7 A hollow cylinder 19 is vertically rotatably mounted on the frame 11, and the active disk 15 is disposed on the outer wall of the hollow cylinder 19.

[0069] A bracket 20 is provided on the frame 11, and a motor 21 is vertically mounted on the bracket 20. A drive pulley 22 is provided at the output end of the motor 21. A driven pulley 23 is provided on the outer wall of the hollow cylinder 19. The drive pulley 22 and the driven pulley 23 are connected by a belt 24.

[0070] In this embodiment, when the motor 21 is started, the output of the motor 21 will drive the drive pulley 22 to rotate. At the same time, the hollow cylinder 19 will follow the drive pulley 22 to rotate through the driven pulley 23 and the belt 24, thereby causing the drive disc 15 fixed on the hollow cylinder 19 to rotate.

[0071] Please see Figure 6 , Figure 9 The clamping assembly includes a frame plate 25 disposed on the frame 11 and a guide rod 26 horizontally rotatably disposed on the frame plate 25. Two clamping plates 27 are symmetrically and slidably disposed on the guide rod 26. A bidirectional lead screw 28 is rotatably disposed on the frame plate 25. One end of each of the two clamping plates 27 is threaded into the outer wall of the bidirectional lead screw 28.

[0072] The outer wall of the bidirectional lead screw 28 is provided with a driven bevel gear 29. A first rotating rod 30 is vertically rotatably mounted on the frame 11. One end of the first rotating rod 30 is connected to the first driven disk 16, and the other end of the first rotating rod 30 is provided with a driving bevel gear 31. The driving bevel gear 31 meshes with the driven bevel gear 29.

[0073] In this embodiment, the sealing cap 3 is first placed on the top of the cylinder 1, so that the positions of the multiple locking blocks 8 correspond to the positions of the multiple through slots 10;

[0074] Since one end of the first rotating rod 30 is connected to the first driven disk 16, the first rotating rod 30 will rotate along with the first driven disk 16 as it rotates.

[0075] Furthermore, since the driving bevel gear 31 fixed at the other end of the first rotating rod 30 meshes with the driven bevel gear 29 fixed on the outer wall of the double-acting screw 28, the double-acting screw 28 will rotate following the first rotating rod 30.

[0076] Since the outer wall of the bidirectional lead screw 28 is threaded with two clamping plates 27, and both clamping plates 27 are slidably engaged with the guide rod 26, the two clamping plates 27 will move closer to each other during the rotation of the bidirectional lead screw 28, thereby clamping and fixing the outer wall of the sealing cover 3.

[0077] Please see Figure 10 , Figure 11 The lifting assembly includes a second rotating rod 32 that is rotatably engaged with the base plate 12. The bottom end of the second rotating rod 32 is rotatably connected to the frame 11, and the top end of the second rotating rod 32 is connected to the second driven plate 17.

[0078] The outer wall of the second rotating rod 32 is provided with a spiral groove 33, and a ball bearing 34 is rolled and fitted inside the base plate 12. The ball bearing 34 is also fitted inside the spiral groove 33 and slides in cooperation.

[0079] In this embodiment, since the top end of the second rotating rod 32 is connected to the second driven disk 17, the second rotating rod 32 will rotate along with the second driven disk 17 as it rotates.

[0080] Furthermore, since the second rotating rod 32 is rotatably engaged with the base plate 12, and the rolling ball 34 inside the base plate 12 is slidably engaged with the spiral groove 33 on the outer wall of the second rotating rod 32, the base plate 12 will drive the rotating seat 13 to move upward during the rotation of the second rotating rod 32, thereby causing the cylinder 1 installed inside the rotating seat 13 to move closer to the sealing cover 3.

[0081] As the cylinder 1 approaches the sealing cover 3, multiple locking blocks 8 on the outer wall of the sealing cover 3 will pass through multiple through slots 10 and enter the interior of the cylinder 1. During this process, the mounting spring 7 will be squeezed by the sealing cover 3 and the retaining ring 6, causing the sealing cover 3 to have an upward tendency and be unable to move under the action of the clamping assembly.

[0082] Please see Figure 3 , Figure 6 , Figure 12 The rotating assembly includes a first gear 35 disposed on the outer wall of the rotating base 13 and a rotating cylinder 36 rotatably disposed on the base plate 12. The outer wall of the rotating cylinder 36 is provided with a second gear 37 that meshes with the first gear 35.

[0083] The frame 11 is rotatably equipped with a third rotating rod 38, the top of the third rotating rod 38 is connected to the third driven disk 18, and the second gear 37 is sleeved on the outer wall of the third rotating rod 38 and slides in cooperation with it.

[0084] The second gear 37 has a limiting groove 3701 inside, and the outer wall of the third rotating rod 38 is provided with a limiting post 3801 along its length direction. The limiting post 3801 is located inside the limiting groove 3701 and slides with each other.

[0085] In this embodiment, since gear 35 and gear 37 mesh with each other, when gear 37 rotates, gear 35 will drive the rotating seat 13 to rotate as well, so that the rotating seat 13 drives the cylinder 1 to rotate through the locking groove 14, and the multiple slots 9 on the top of the cylinder 1 correspond to the multiple blocks 8 on the outer wall of the sealing cover 3. Then, the clamping assembly is used to release the fixing of the sealing cover 3. Under the action of the installation spring 7, the sealing cover 3 will drive the multiple blocks 8 to enter the multiple slots 9 respectively, thereby realizing the installation of the sealing cover 3 and the cylinder 1.

[0086] Since the second gear 37 is sleeved on the outer wall of the third rotating rod 38 and slides with it, the second gear 37 will slide on the outer wall of the third rotating rod 38 as it moves upward with the base plate 12.

[0087] Since the limiting post 3801 is located inside the limiting groove 3701 and slides with it, when the second gear 37 moves upward, the limiting post 3801 will slide with the limiting groove 3701 and will not affect the movement of the second gear 37. However, when the third rotating rod 38 rotates, the third rotating rod 38 will drive the second gear 37 to rotate through the interaction between the limiting post 3801 and the limiting groove 3701.

[0088] Please see Figures 1-12 A method for assembling a shock absorber for a vehicle suspension using the assembly device described above includes the following steps:

[0089] Step 1: Install the cylinder into the inside of the rotary seat, so that the bottom of the cylinder is located in the locking groove, so that the cylinder will move synchronously with the rotary seat when it rotates and rises.

[0090] Step 2: Insert the tie rod inside the cylinder barrel so that the limiting ring abuts against the shock-absorbing spring. Then place the sealing cover on the top of the cylinder barrel, and make the multiple locking blocks correspond to the positions of the multiple through slots respectively.

[0091] Step 3: The sealing cap is clamped and fixed by the cooperation of the drive mechanism and clamping components in the assembly device.

[0092] Step 4: The lifting assembly is driven by the drive mechanism, which causes the rotary table to move the cylinder vertically upward. At the same time, multiple locking blocks on the sealing cover will pass through multiple slots and enter the cylinder, and the mounting spring will be compressed.

[0093] Step 5: The rotating component in the assembly device works in conjunction with the drive mechanism to make the cylinder rotate with the rotary table, so that the multiple slots on the top of the cylinder correspond to the multiple blocks on the sealing cover. Then, the clamping component releases the fixing of the sealing cover, and the reset force of the installation spring makes the multiple slots and multiple blocks interlock.

[0094] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.

[0095] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

6. A method for assembling a shock absorber for an automotive suspension using the assembly apparatus as described in claim 5, characterized in that, Includes the following steps: Step 1: Install the cylinder into the inside of the rotary seat, so that the bottom of the cylinder is located in the locking groove, so that the cylinder will move synchronously with the rotary seat when it rotates and rises. Step 2: Insert the tie rod inside the cylinder barrel so that the limiting ring abuts against the shock-absorbing spring. Then place the sealing cover on the top of the cylinder barrel, and make the multiple locking blocks correspond to the positions of the multiple through slots respectively. Step 3: The sealing cap is clamped and fixed by the cooperation of the drive mechanism and clamping components in the assembly device. Step 4: The lifting assembly is driven by the drive mechanism, which causes the rotary table to move the cylinder vertically upward. At the same time, multiple locking blocks on the sealing cover will pass through multiple slots and enter the cylinder, and the mounting spring will be compressed. Step 5: The rotating component in the assembly device works in conjunction with the drive mechanism to make the cylinder follow the rotating seat to rotate, so that the multiple slots on the top of the cylinder correspond to the multiple blocks on the sealing cover. Then, the clamping component is used to release the sealing cover, and the power of the spring is used to reset so that the multiple slots and multiple blocks are locked together.
