Abstract
Description
Technical Field
[0001] This invention relates to the field of rubber sleeve pressing technology, specifically to a rubber sleeve pressing device for automotive suspension sleeve holes. Background Technology
[0002] The torsion beam suspension is a key structure in the rear suspension system of a car. It consists of a crossbeam, trailing arms, and damping components. If the bushings installed inside the trailing arms malfunction, the entire torsion beam suspension will produce abnormal noises. In severe cases, this can affect the driving and riding experience and pose a significant safety hazard. To facilitate the replacement of the bushings inside the torsion beam suspension that cause abnormal noises, it is essential to use specific pressing equipment.
[0003] Because the torsion beam suspension supports two tires, it is relatively heavy. Replacing the inner bushings of a torsion beam suspension requires sequentially removing components such as the shock absorber, brake lines, and handbrake cable. The torsion beam suspension is then supported with clamps until the trailing arms are exposed. The old bushings need to be forcibly removed, and the new bushings need to be pressed in using hydraulic clamps. However, this process has drawbacks. After removing the old bushings, cleaning fluid is insufficient to effectively clean the inner bushing holes of the trailing arms. If debris or particles remain inside the inner bushing holes, the new bushings, which are then pressed in using hydraulic clamps, will be scratched by these debris and particles, thus reducing the lifespan of the new bushings.
[0004] In view of this, a rubber sleeve pressing device for automotive suspension sleeve holes was designed to solve the above problems. Summary of the Invention

[0036] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:
[0037] 1. This invention involves suspending the car and then pushing the device directly below the torsion beam suspension until the hole wall cleaning mechanism and the bushing pressing mechanism are located at both ends of the torsion beam suspension trailing arm. As the hole wall cleaning mechanism enters the bushing hole inside the trailing arm, the dirt and particulate matter inside the bushing hole are flushed with a washing solution. The flushed wastewater is simultaneously recycled to prevent the washing solution from overflowing from the bushing hole inside the trailing arm and to avoid interfering with the working area.
[0038] 2. This invention utilizes a rubber sleeve pressing mechanism to pre-install new rubber sleeves. As the pressure plate pushes the new rubber sleeve towards the inner end of the sleeve hole, the old rubber sleeve squeezed out during washing will re-enter the sleeve hole. The old rubber sleeve is used to scrape away the dirt accumulated on the inner wall of the sleeve hole. During the process of the new rubber sleeve being squeezed into the sleeve hole of the longitudinal arm, wear caused by particles or impurities can be avoided, thus realizing the rapid replacement of old and new rubber sleeves.
[0039] 3. By applying support to the inner beam of the longitudinal arm, the device expands vertically and, in conjunction with jacks, provides stable support to the interior of the longitudinal arm. This ensures that while bolts are installed and removed from the longitudinal arm sleeve hole, it also provides protection for workers under the vehicle during maintenance, preventing abnormal docking problems caused by collapse of the longitudinal arm sleeve hole port.

[0056] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0057] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.
[0058] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a rubber sleeve pressing device for automotive suspension sleeve holes.
[0059] Example 1:
[0060] Combination Figures 1-11 As shown, the present invention provides a rubber sleeve pressing device for automotive suspension sleeve holes, including a suspension lifting mechanism 100, a suspension matching mechanism 200 disposed on the suspension lifting mechanism 100, a hole wall cleaning mechanism 300 disposed on the suspension matching mechanism 200, and a rubber sleeve pressing mechanism 400 disposed on the suspension matching mechanism 200. The suspension lifting mechanism 100 is used to provide a sufficiently stable lifting platform for the suspension matching mechanism 200, and cooperates with the hole wall cleaning mechanism 300 and the rubber sleeve pressing mechanism 400 to effectively connect the two ports of the rear axle. The suspension matching mechanism 200 is used to provide a sliding platform for the hole wall cleaning mechanism 300 and the rubber sleeve pressing mechanism 400 to move equidistantly. The hole wall cleaning mechanism 300 is used to provide a cleaning carrier for the inner wall of the sleeve hole, and the rubber sleeve pressing mechanism 400 is used to provide a pressure carrier for replacing the rubber sleeve in the sleeve hole.
[0061] The hole wall cleaning mechanism 300 includes an outer cylinder 310 and a plug 350 movably installed inside the outer cylinder 310, and a pressure-bearing member 320 set at the outer end of the outer cylinder 310. The plug 350 is composed of an I-shaped end and a sliding column, and the I-shaped end has a slot, while the sliding column has a groove.
[0062] Furthermore, a gasket 360 is provided in the middle of the inner cavity of the I-shaped end;
[0063] A drainage component 370 is installed inside the plug 350;
[0064] The drainage assembly 370 includes a main housing 371 and a secondary housing 372 disposed inside the groove, an injection pipe 373 disposed between the main housing 371 and the secondary housing 372, and a drain pipe 374.
[0065] The inside of the drain tube 374 has two cavities, and the inner cavity of the injection tube 373 is connected to one cavity at the outer end of the drain tube 374, while the other cavity of the drain tube 374 is connected to the cavity of the combined main shell 371 and secondary shell 372.
[0066] The pressure-bearing component 320 consists of a gasket and two L-shaped feet;
[0067] The pressure-bearing component 320 is provided with a crossbar 330 inside, and the inner end of the crossbar 330 is adapted to penetrate into the interior of the sliding column, and a second spring 340 is provided on the outside of the crossbar 330.
[0068] The rubber sleeve pressing mechanism 400 includes a pre-assembly cylinder 410, a pressure stabilizing component 450 disposed inside the pre-assembly cylinder 410, an end rod 460 disposed on the pressure stabilizing component 450, a ring washer 480 installed on the outer end of the end rod 460, a pressure plate 490 disposed on the ring washer 480 and located inside the pre-assembly cylinder 410, and a rubber sleeve 440 disposed inside the pre-assembly cylinder 410 and subjected to pressure by the pressure plate 490.
[0069] The pressure plate 420 is installed on the pre-loading cylinder 410, the insert rod 430 is disposed inside the pressure plate 420, and the second spring and third spring 470 are disposed outside the end rod 460;
[0070] The end rod 460 is adapted to extend through to the outside of the first support 240, and one end of the second spring and the third spring 470 is pressed against the first support 240.
[0071] After the car is lifted, use a wrench to remove one of the rear axle wheels that is raised. At this time, the torsion beam suspension can be exposed. Then, use a socket wrench and a wrench to remove the bolts on the torsion beam suspension. At this time, the suspension lifting mechanism 100, which is in a compressed state, will be located directly below the trailing arm sleeve hole.
[0072] When the first hydraulic component 170 is running, its internal hydraulic rod will cooperate with the two sets of lifting frames 140 to lift the top plate 120 upward. At this time, the suspension positioning mechanism 200 installed on the top of the top plate 120 can advance the horizontally placed hole wall cleaning mechanism 300 and the rubber sleeve pressing mechanism 400 towards both ends of the longitudinal arm sleeve hole until the plug 350 and the pre-installed cylinder 410 are aligned with the two ends of the longitudinal arm sleeve hole.
[0073] Next, the second hydraulic component 215 is operated. At this time, the hydraulic rod inside the second hydraulic component 215 will pull the traction component 216 and the end plate 217 to descend. The two cantilever arms 219, which are movably installed at both ends of the end plate 217, can apply a constant pressure traction force to the two bottom support slide plates 270. At this time, the first support frame 240 and the second support frame 250, which are combined and fixed, can align and press the horizontal hole wall cleaning mechanism 300 and the rubber sleeve pressing mechanism 400 toward the longitudinal arm sleeve hole. After the plug 350 is attached to the longitudinal arm sleeve hole, the cross bar 330 can be struck with a tool. The impacted slide bar can squeeze out the old rubber sleeve in the longitudinal arm sleeve hole. The old rubber sleeve will eventually be stored in the inner cavity of the pre-loading cylinder 410. The plug 350 can then cooperate with the drainage component 370 to transfer the washing solution into the longitudinal arm sleeve hole. Finally, the washing solution is used to thoroughly clean the longitudinal arm sleeve hole.
[0074] After the longitudinal arm sleeve hole is cleaned, the advance screw 290 can be controlled to rotate clockwise. At this time, the pressure stabilizer 450 will be pressed and move stably. The end rod 460 installed on the pressure stabilizer 450 will push the ring washer 480 and the pressure plate 490 towards the port of the longitudinal arm sleeve hole. Finally, the old rubber sleeve is squeezed back into the longitudinal arm sleeve hole, which can remove the dirt. The new rubber sleeve will also squeeze out the old rubber sleeve again. At this time, the new rubber sleeve can be effectively transferred into the interior of the longitudinal arm sleeve hole.
[0075] Example 2:
[0076] Combination Figures 1-4 As shown, based on Embodiment 1, the suspension lifting mechanism 100 includes a base 110 placed on the ground and two sets of lifting outer frames 140, four limiting rods 180 set on the top of the base 110, and a top plate 120 movably installed on the four limiting rods 180.
[0077] Both ends of the base 110 are equipped with pulleys.
[0078] Preferably, after the base 110 moves along the ground to the bottom of the car, the roof 120 is lifted upwards under pressure, and finally the two sets of lifting frames 140 can provide stabilizing protection for the lifting of the roof 120.
[0079] Both the top of the base 110 and the bottom of the top plate 120 are provided with clamps 130;
[0080] Two sets of lifting outer frames 140 are installed inside the base 110 and the top plate 120;
[0081] A first base 150 is provided in the middle of the top surface of the base 110;
[0082] A second base 160 is provided in the middle of the bottom surface of the top plate 120;
[0083] A first hydraulic component 170 is disposed between the first base 150 and the second base 160.
[0084] Preferably, there are four sets of clamps 130 in total. Four clamps 130 are fixedly installed on the base 110, and the other four clamps 130 are fixedly installed on the top plate 120. At this time, the two sets of lifting frames 140 will be respectively set between the two adjacent sets of clamps 130. As the first hydraulic component 170 operates, the two sets of lifting frames 140 can cooperate with the lifting and lowering of the hydraulic rods in the first hydraulic component 170 to push the top plate 120 to extend smoothly, so as to ensure the pressure resistance and stability of the suspension positioning mechanism 200 after the overall lifting and lowering.
[0085] Example 3:
[0086] Combination Figure 5 and Figure 11As shown, based on Embodiment 1, the suspension matching mechanism 200 includes a pressure-bearing component 210 and two baffles 220, two bottom support plates 270 disposed on the pressure-bearing component 210, a first support 240 disposed on one bottom support plate 270, and a second support 250 disposed on the other bottom support plate 270.
[0087] Preferably, one of the sealing gaskets 260 is bolted to the top of the first support 240, while the other sealing gasket 260 is bolted to the top of the second support 250. At this time, the fixed hole wall cleaning mechanism 300 and the rubber sleeve pressing mechanism 400 can be on the same horizontal plane to provide a pressing and replacement platform for both ends of the torsion beam suspension.
[0088] Both the top of the first support 240 and the second support 250 are provided with sealing gaskets 260;
[0089] The inner side of the second support 250 is provided with a beam frame 280, and the inside of the beam frame 280 is provided with a progressive screw rod 290;
[0090] Positioning plates 230 are provided inside the two baffles 220, and the screw sleeves on the top of the positioning plates 230 are adapted to be installed on the threaded section of the lead screw 290.
[0091] Preferably, the beam frame 280 has a transverse hole inside, and the advancing screw 290 is adapted to pass through the transverse hole. As the outer end wheel of the advancing screw 290 rotates clockwise, the advancing screw 290 will advance along the screw sleeve on the top of the positioning plate 230. Finally, the pressure stabilizing component 450 will pull the end rod 460 and the ring washer 480 to move laterally. At this time, the rubber sleeve 440 pre-installed from the top slot of the pre-installed cylinder 410 can be squeezed by the pressure plate 490 and squeezed into the longitudinal arm sleeve hole.
[0092] Example 4:
[0093] Combination Figures 1-6 As shown, based on Embodiment 1, the pressure-bearing component 210 includes two outer plates 211, and a groove is provided in the middle of the outer plate 211, and a vertical rod 212 is provided in the middle of the groove, and a first spring 213 is provided on the outside of the vertical rod 212.
[0094] A stabilizing plate 218 is provided on the outside of the vertical rod 212, and the top of the first spring 213 is adapted to bear pressure on the bottom of the stabilizing plate 218. An end plate 217 is provided on the outside of the stabilizing plate 218.
[0095] Two clamps 214 are provided between the two outer plates 211.
[0096] Preferably, the two outer plates 211, which are fixed by the two clamps 214, are fixed to the top of the top plate 120 by welding or bolts. At this time, the second hydraulic component 215, which is set in one of the clamps 214, will be effectively protected by the combined baffle 220 and positioning plate 230. As the second hydraulic component 215 runs, its internal hydraulic rod will pull the traction component 216 to descend. Finally, the end plate 217 and the stabilizing plate 218 will provide effective traction force to the two cantilever 219, so that the two bottom support slide plates 270 can be extended at equal distances.
[0097] One of the clamps 214 has a horizontally placed second hydraulic component 215 installed inside, and a traction component 216 is installed at the outer end of the hydraulic rod inside the second hydraulic component 215, while the top end of the traction component 216 is movably installed on the end plate 217.
[0098] Two symmetrically distributed cantilever arms 219 are movably installed at both ends of the end plate 217;
[0099] The top of the outer panel 211 is provided with a U-shaped top plate, and two bottom support slide plates 270 are movably installed on the inner side of the two U-shaped top plates;
[0100] The top of the cantilever 219 is movably mounted on the bottom support plate 270;
[0101] The inner end of the lead screw 290 is provided with a T-shaped plug, and the T-shaped plug is provided with a washer and a bolt.
[0102] Preferably, the two U-shaped top plates set on the two outer plates 211 are used to provide limiting constraints on the two bottom support slide plates 270. At this time, the stabilizing plate 218 bearing the pressure of the two vertical rods 212 can provide sufficient pressure-resistant constraint force for the lifting and lowering of the two cantilever 219. Ultimately, it can ensure the stable clamping and docking of the plug 350 and the pre-installed cylinder 410 to both ends of the sleeve hole, thereby avoiding scratches and wear due to the error of the sleeve hole port during the replacement of the rubber sleeve.
[0103] The working principle and usage process of this invention: After the car is lifted, the torsion beam suspension after the bolts are removed will tend to fall due to gravity. The torsion beam suspension is generally heavy. The removal of the old rubber bushing and the pressing of the new rubber bushing are entirely done manually, which not only increases the workload of workers, but also causes some interference to the work area due to the spraying of cleaning fluid inside the bushing hole.
[0104] The device lifts the entire car using an external hoisting device until there is enough space for maintenance between the car and the ground. Then, the compressed device is delivered to the underside of the suspended car until the hole wall cleaning mechanism 300 is located at the inner end of the sleeve hole. At this time, the rubber sleeve pressing mechanism 400 will be located at the outer end of the sleeve hole. As the first hydraulic component 170 operates, its internal hydraulic rod will push the second base 160 and the top plate 120 to drive the suspension matching mechanism 200 to rise as a whole. At the same time, the two sets of lifting frames 140 set on the base 110 and the top plate 120 can rise stably. At this time, the upward lifting suspension matching mechanism 200 can drive the hole wall cleaning mechanism 300 and the rubber sleeve pressing mechanism 400 to adapt and approach the two ends of the sleeve hole. At this time, the plug 350 will first be subjected to the pressure of the old rubber sleeve inside the sleeve hole and extend outward. Then, the worker only needs to use a tool to knock the crossbar 330, and the old rubber sleeve will enter the pre-installation cylinder 410.
[0105] The plug 350 is located in the inner cavity of the sleeve hole. After the main housing 371 injects the washing solution into the drain pipe 374, the washing solution will wash the inner wall of the sleeve hole along the groove at one end of the plug 350. The dirt after washing will be transferred from the groove at the other end of the plug 350. Finally, the transferred sewage can be discharged from the inner cavity of the drain pipe 374, and the sewage will be released from the main housing 371 to the outside.
[0106] With the outer end of the plug 350 facing the outer end of the longitudinal arm sleeve hole and the outer end of the pre-installed cylinder 410 facing the inner end of the longitudinal arm sleeve hole, the second hydraulic component 215 can be operated. At this time, the hydraulic rod inside the second hydraulic component 215 will pull the traction component 216 to descend. The end plate 217 and the stabilizing plate 218, which are movably installed at the top of the traction component 216, will descend smoothly along the slide in the middle of the two outer plates 211. Finally, the end plate 217 will pull the two cantilever 219 to descend at the same speed. The two cantilever 219 can then apply a constant traction force to the combined first support frame 240, bottom support slide plate 270, second support frame 250, and bottom support slide plate 270. At this time, the fixed hole wall cleaning mechanism 300 and the rubber sleeve pressing mechanism 400 can then fit and press the two ends of the longitudinal arm sleeve hole.
[0107] Once the two ends of the longitudinal arm sleeve hole are fully aligned, the wheel at the outer end of the advancing screw 290 can be operated. At this time, the advancing screw 290 can rotate stably along the threaded sleeve at the top of the positioning plate 230. The other end of the advancing screw 290 will pull the pressure stabilizing component 450 to apply pressure along the groove at the bottom of the pre-installed cylinder 410 towards the longitudinal arm sleeve hole. The pressure stabilizing component 450 will then push the end rod 460 and the ring washer 480 closer to the inner end of the longitudinal arm sleeve hole, and finally the pressure plate 49 installed on the ring washer 480 will be placed inside. The old rubber sleeve and the new rubber sleeve 440 can be squeezed from the inner cavity of the pre-loading cylinder 410 into the longitudinal arm sleeve hole. At this time, the old rubber sleeve can scrape off the dirt that has not been completely cleaned from the inner wall of the longitudinal arm sleeve hole. Finally, the old rubber sleeve will be squeezed by the new rubber sleeve 440 and squeeze out the plug 350, while the new rubber sleeve 440 can be completely transferred into the inner wall of the longitudinal arm sleeve hole. This process can improve the complete cleaning of the inner wall of the longitudinal arm sleeve hole while avoiding the interference of the washing solution with the working environment.
