Description

Technical Field

[0001] The utility model relates to the technical field of automobile suspension, in particular to a controllable suspension vibration reduction device for an automobile chassis. Background Art

[0002] Automobile shock absorbers are an important component on vehicles, which are designed to reduce the vibration and bumps caused by uneven and bumpy roads during driving. Controllable suspension shock absorbers are usually used in vehicle suspension systems to improve ride comfort, stability and safety by absorbing and reducing the impact force on the vehicle during driving.

[0003] A Chinese patent with application number CN202122001840.8 discloses a vibration reduction device for automobile suspension. The utility model can control the length of the vibration reduction spring through the vibration reduction spring assembly and the hydraulic assembly, and can adjust the preload force of the vibration reduction spring. When the vehicle passes over a bumpy road, the length of the vibration reduction spring is controlled to extend, and the vibration transmitted to the vehicle body is reduced by absorbing energy through the deformation of the vibration reduction spring. When the vehicle is driving at high speed or turning, the length of the vibration reduction spring is controlled to shorten, so that the vibration reduction spring can provide stable support for the vehicle body and prevent the vehicle from tilting. The utility model adjusts the hardness of the suspension by controlling the length of the spring, thereby improving the vibration reduction effect. However, the existing structure is that the damper and the shock absorber are integrated. When the shock absorber cylinder is damaged or needs to be replaced, the overall replacement and maintenance work will become more difficult, increasing the cost of vehicle maintenance.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The utility model provides Figure 1 The controllable suspension vibration reduction device for automobile chassis shown in the figure comprises: two fixed plates 1, a damper 2 and a vibration reduction spring 3 are installed between the two fixed plates 1, the vibration reduction spring 3 is arranged on the outer wall of the damper 2, and an adjustment mechanism 6 for adjusting the vibration reduction strength of the vibration reduction spring 3 is arranged between the two fixed plates 1.

[0030] Regarding the above-mentioned adjustment mechanism 6, as Figure 2 As shown, the adjustment mechanism 6 includes a fixed block 64 fixed on both sides of the two fixed disks 1 and an adjustment rod 63 installed between the two fixed blocks 64, one end of the adjustment rod 63 passes through the upper fixed block 64 and extends upward relative to the upper fixed disk 1, and a movable sleeve 61 is installed on the extension portion. The bottom of the movable sleeve 61 is in conflict with the top of the upper fixed disk 1, and the outer wall of the adjustment rod 63 is provided with a second thread groove, and the outer wall of the movable sleeve 61 is screwed with a second screw 62, and the second screw 62 cooperates with the second thread groove. Based on this, through the mutual cooperation of the second screw 62 and the second threaded groove, the movable sleeve 61 is fixed on the outer wall of the adjusting rod 63. At this time, the vehicle's bumps drive the damper 2 and the shock-absorbing spring 3 to contract. At the same time, the bottom fixed plate 1 is driven to move upward, and the upward movement of the bottom fixed plate 1 drives the adjusting rod 63 to move upward, so that the adjusting rod 63 drives the movable sleeve 61 to move upward, and then the damper 2 is driven to reset through the elastic force of the shock-absorbing spring 3, so that the adjusting rod 63 is reset synchronously, and the reset of the adjusting rod 63 drives the movable sleeve 61 to reset, thereby reducing the bumps generated during the driving of the car.

[0031] As can be seen from the above, when in use, the two fixed plates 1 are installed on the car, and the second screw 62 is first rotated to separate it from the second thread groove. Through the separation of the second screw 62 and the second thread groove, the movable sleeve 61 can move on the outer wall of the adjusting rod 63, and then the other fixed plate 1 is pressed to drive the damper 2 and the shock absorbing spring 3 to contract, so that the distance between the two fixed plates 1 can be adjusted, thereby completing the control and adjustment of the shock absorbing device of the car chassis.

[0032] refer to Figure 3As shown, a disassembly mechanism 4 is located on the lower fixed plate 1, and the disassembly mechanism 4 is used to disassemble the damper 2 and the damping spring 3. The disassembly mechanism 4 includes blocks 42 fixed on both sides of the bottom of the damper 2 and a control seat 43 installed at the bottom of the lower fixed plate 1. A through groove is opened in the middle of the lower fixed plate 1. The damper 2 extends to the bottom of the through groove and is connected to the control seat 43. A fixing mechanism for fixing the block 42 is arranged between the block 42 and the control seat 43. The fixing mechanism includes a first screw opened inside the block 42. A groove and a reinforcement seat fixed on one side of the control seat 43, a first screw 44 is threaded inside the reinforcement seat, the first screw 44 cooperates with the first thread groove, a positioning mechanism for positioning the control seat 43 is arranged between the control seat 43 and the lower fixed plate 1, the positioning mechanism includes an extension seat 41 fixed on one side of the lower fixed plate 1 and positioning plates 45 installed on both sides of the control seat 43, a groove for plugging the positioning plate 45 is opened at the bottom of the lower fixed plate 1, and a plug-in mechanism for plugging the positioning plate 45 is arranged between the groove and the positioning plate 45.

[0033] Through the above technical solution:

[0034] When in use, the first screw 44 is rotated to separate it from the first thread groove. By separating the first screw 44 from the first thread groove, the block 42 is no longer fixed. Then, the damper 2 is pulled to drive the block 42 to move, so that the block 42 is away from the through groove, so that the damper 2 can be separated from the fixed plate 1, so that when the damper 2 is damaged or needs to be replaced, the maintenance work becomes simpler, and the cost and complexity of vehicle maintenance are reduced. At the same time, it solves the problem that if the shock absorber cylinder cannot be disassembled and replaced in time in the existing device, the vibration reduction performance may be reduced, thereby affecting driving comfort and safety.

[0035] Regarding the above-mentioned plug-in mechanism, Figure 4 As shown, the plug-in mechanism includes a fixed groove opened on one side of the lower fixed plate 1 and a slot opened inside the positioning plate 45, a plug rod is inserted inside the fixed groove, the plug rod extends to one side of the groove and plugs into the slot, and a reset mechanism for resetting the plug rod is provided between the plug rod and the extension seat 41. Based on this, the plug rod is pulled to move in the fixed groove, and the plug rod is separated from the slot by the movement of the plug rod, and the positioning plate 45 is movable by the mutual separation of the plug rod and the slot, thereby facilitating the removal of the control seat 43.

[0036] Further, regarding the above-mentioned reset mechanism, Figure 4As shown, the reset mechanism includes a baffle fixed to the outer wall of the plug rod and a first spring 46 connected between the baffle and the extension seat 41, and the baffle cooperates with the fixing groove. Based on this, the movement of the plug rod drives the baffle to move, and the movement of the baffle drives the first spring 46 to contract. The contraction of the first spring 46 allows the staff to reset the plug rod when releasing it. At the same time, the elastic force of the first spring 46 can strengthen the connection between the plug rod and the slot to prevent the plug rod from accidentally falling off.

[0037] In addition, refer to Figure 5 As shown, a cleaning mechanism 5 for cleaning the adjusting rod 63 is provided between the adjusting rod 63 and the upper fixed block 64, the cleaning mechanism 5 comprises a cleaning sleeve 52 sleeved on the outer wall of the adjusting rod 63 and a limiting plate 53 fixed on the top of the cleaning sleeve 52, a groove cavity for plugging the limiting plate 53 is provided at the bottom of the upper fixed block 64, a plug-in plate 54 is plugged into one side of the groove cavity, the plug-in plate 54 is plugged into the limiting plate 53, and the plug-in plate 54 extends to one side of the upper fixed block 64 and is fixed with a control board, and a second spring 51 is connected between the control board and the upper fixed block 64.

[0038] Through the above technical solution:

[0039] When in use, the control plate is pulled to drive the second spring 51 to be stretched, and the stretching of the second spring 51 separates the plug plate 54 from the limit plate 53. After the plug plate 54 and the limit plate 53 are separated from each other, the limit plate 53 is no longer limited. Then the cleaning sleeve 52 is pulled up and down to cause it to scratch the outer wall of the adjusting rod 63, so that the outer wall of the adjusting rod 63 can be cleaned, and the dirt and impurities attached to its surface can be effectively removed to ensure the normal operation of the shock absorbing device, thereby helping to maintain the performance of the shock absorbing system and improve the stability and comfort of the vehicle. At the same time, regular cleaning of the outer wall of the adjusting rod 63 can reduce the wear of the adjusting rod 63 by impurities and extend the service life of the shock absorbing device.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
