Description

Technical Field

[0001] This utility model relates to the field of automotive suspension system technology, and in particular to an anti-roll multi-link air suspension mechanism. Background Technology

[0002] Air suspension systems, which combine the comfort of sedans with the performance of off-road vehicles, are widely used in the automotive industry. They can flexibly raise or lower the chassis height according to road undulations, enabling vehicles to adapt to various complex road conditions and driving needs. They are especially commonly used in off-road vehicles that frequently drive on harsh road conditions (such as mud, water crossings, and gravel roads) to ensure smooth passage.

[0003] The anti-roll multi-link air suspension system mainly consists of three core modules: air spring module, multi-link guide mechanism, and dynamic control system. The air spring module adopts a rubber bellows structure, which provides elastic support by compressing air volume changes. The multi-link guide mechanism is usually composed of 3-5 links forming a trapezoidal or X-shaped structure. The dynamic control system includes a height sensor, acceleration sensor, ECU (electronic control unit), and damping adjustable shock absorber. Its working principle is as follows: when the vehicle body sinks due to load or road conditions, the height sensor monitors the change and transmits the data to the ECU. The ECU activates the air compressor, which inflates the air spring through the accumulator, causing the airbag to expand and lift the vehicle body. Conversely, when the load is reduced, the solenoid valve discharges the air in the spring, and the vehicle body weight compresses the airbag to achieve height reduction. When turning and braking, the acceleration sensor signal is triggered, and the ECU immediately strengthens the suspension support of the outer wheel or front wheel to reduce body roll and center of gravity shift.

[0004] However, existing anti-roll multi-link air suspension systems have many problems during use. Among them, the airbag is exposed under the car. When the car is in motion, the wheels will kick up gravel from the road. If this flying gravel hits the airbag, it can easily cause the airbag to rupture and affect its service life.

[0005] Therefore, this utility model proposes an anti-roll multi-link air suspension mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an anti-roll multi-link air suspension mechanism to solve the problems mentioned in the background art.

[0008] Preferably, an upper mounting base is fixedly connected to the upper surface of the fixed top plate, and a fixing through hole is provided through the outer surface of the upper mounting base. A lower mounting base is fixedly connected to the lower surface of the fixed bottom plate, and a fixing through hole is provided through the outer surface of the lower mounting base.

[0009] Preferably, the cage-type protective assembly includes an arc-shaped mounting component that snaps into the inner wall of the annular groove, a connecting shell is fixedly connected to one side of the arc-shaped mounting component, and a fixing rod is fixedly connected to the inner side wall of the connecting shell.

[0010] Preferably, a connecting block is rotatably connected to the outer wall of the fixing rod, an arc-shaped mounting component two is fixedly connected to the outer wall of the connecting block, and a connecting plate one is fixedly connected to the side of the arc-shaped mounting component two away from the connecting block.

[0012] Preferably, a threaded rod is threadedly connected to the inner wall of the first threaded groove, and a knob is fixedly connected to the end of the threaded rod away from the first threaded groove. Multiple screw blocks are fixedly connected to the outer surface of the knob, and the screw blocks are distributed in a ring array.

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figures 1 to 6 This utility model provides a technical solution: an anti-roll multi-link air suspension mechanism, including a fixed top plate 1, an airbag body 6 fixedly connected to the lower surface of the fixed top plate 1, a fixed bottom plate 3 fixedly connected to the side of the airbag body 6 away from the fixed top plate 1, a fixing ring 7 fixedly connected to the upper surface of the fixed bottom plate 3 and the lower surface of the fixed top plate 1, an annular groove 8 opened on the outer surface of the fixing ring 7, a cage-type protective component 5 provided on the inner wall of the annular groove 8, the cage-type protective component 5 being lightweight and not affecting the suspension response speed; an upper mounting seat 2 fixedly connected to the upper surface of the fixed top plate 1, a fixing through hole 1 opened through the outer surface of the upper mounting seat 2, a lower mounting seat 4 fixedly connected to the lower surface of the fixed bottom plate 3, a fixing through hole 2 opened through the outer surface of the lower mounting seat 4, through the fixing through hole 1 on the upper mounting seat 2 and the fixing through hole 2 on the lower mounting seat 4, the airbag body 6 can be securely installed on the anti-roll multi-link air suspension mechanism using bolts or other fasteners.

[0019] In actual use, firstly, align the first fixing through hole on the upper mounting base 2 with the second fixing through hole on the lower mounting base 4. Then, use bolts or other fasteners to pass through these through holes to securely install the airbag body 6 onto the anti-roll multi-link air suspension mechanism, ensuring the airbag body 6 is fixed in position and providing a stable foundation for the subsequent installation of the cage-type protective component 5. Place the arc-shaped mounting part 502 into the annular groove 8 on the fixing ring 7, ensuring that the arc-shaped mounting part 502 fits tightly with the annular groove 8, preparing for the subsequent installation of the arc-shaped mounting part 501. By rotating the connecting block 506 on the outer wall of the fixing rod 507, the arc-shaped mounting part 501 is driven to rotate around the fixing rod 507 as the axis. Slowly rotate the arc-shaped mounting part 2 501 into the annular groove 8 on the fixing ring 7. During this process, pay attention to adjusting the angle to ensure that the arc-shaped mounting part 2 501 can smoothly enter the annular groove 8. After the arc-shaped mounting part 2 501 is rotated to the appropriate position, align the connecting plate 1 509 on the arc-shaped mounting part 2 501 with the connecting plate 2 508 on the arc-shaped mounting part 1 502, ensuring that the threaded grooves 1 and 2 of the two are accurately aligned. Then, the operator holds the screw block and rotates the knob 511 to drive the threaded rod 510 into the threaded grooves 1 and 2, completing the connection between the arc-shaped mounting part 1 502 and the arc-shaped mounting part 2 501, thereby completing the installation of the cage-type protective assembly 5.

[0020] The cage-type protective assembly 5 includes an arc-shaped mounting part 502 that snaps into the inner wall of the annular groove 8. A connecting shell 505 is fixedly connected to one side of the arc-shaped mounting part 502, and a fixing rod 507 is fixedly connected to the inner wall of the connecting shell 505. A connecting block 506 is rotatably connected to the outer wall of the fixing rod 507, and an arc-shaped mounting part 501 is fixedly connected to the outer wall of the connecting block 506. A connecting plate 509 is fixedly connected to the side of the arc-shaped mounting part 501 away from the connecting block 506. A connecting plate 508 is fixedly connected to the side of the arc-shaped mounting part 502 away from the connecting shell 505, and a threaded groove is formed on the outer surface of the connecting plate 509. First, a threaded groove 2 is formed through the outer surface of the connecting plate 2 508; a threaded rod 510 is threadedly connected to the inner wall of the threaded groove 1, and a knob 511 is fixedly connected to the end of the threaded rod 510 away from the threaded groove 1; multiple screw blocks are fixedly connected to the outer surface of the knob 511, and the screw blocks are distributed in a ring array; multiple protective sleeves 504 are fixedly connected to the upper surfaces of the arc-shaped mounting part 1 502 and the arc-shaped mounting part 2 501; a protective rod 503 is slidably connected to the inner wall of the protective sleeve 504; the end of the protective rod 503 away from the protective sleeve 504 is fixedly connected to the lower surface of the arc-shaped mounting part 1 502 and the arc-shaped mounting part 2 501.

[0021] In actual use, the cage-type protective component 5 plays an important role during vehicle operation. The structure composed of the protective rod 503 and the protective sleeve 504 can effectively block flying sand and gravel and other debris, preventing these debris from directly impacting the airbag body 6, thereby preventing the airbag body 6 from being damaged by sand and gravel impact and extending the service life of the airbag body 6. At the same time, since the protective rod 503 and the protective sleeve 504 adopt a sliding connection, when the airbag body 6 expands or contracts due to changes in vehicle load or road conditions, the protective rod 503 can slide within the protective sleeve 504, adjusting to the expansion size of the airbag body 6, always maintaining effective protection for the airbag body 6, and adapting to the needs of the airbag body 6 under different working conditions.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
