Description

Technical Field

[0001] This utility model relates to the field of suspended flow channel plate technology, specifically to an improved structure of a high-performance hydraulic suspended flow channel plate. Background Technology

[0002] With the rapid development of the automotive industry, consumers have put forward higher requirements for the ride comfort and component reliability of automobiles. The vibration generated by the car engine during operation is transmitted to the car body through the suspension system, which not only affects the driving experience but may also shorten the service life of related components. As a core component of automobile vibration reduction and noise reduction, the hydraulic suspension assembly generates damping force through the flow of internal damping fluid between the fluid chambers, effectively counteracting engine vibration. Its performance directly determines the vibration reduction effect of the car.

[0003] The flow channel plate device is a key component of the hydraulic suspension assembly, playing a crucial role in separating the fluid chambers and guiding the flow of damping fluid. Its structural stability directly affects the service life and operational reliability of the hydraulic suspension. In the prior art, a utility model patent with publication number CN213451478U, entitled "Flow Channel Plate Device for Hydraulic Suspension, Hydraulic Suspension Assembly and Automobile," provides a typical flow channel plate device structure. This device includes a flow channel plate body, a decoupling membrane, and a flow channel cover plate arranged sequentially along the axial direction. The flow channel plate body extends axially to form a first annular sidewall, and the decoupling membrane is fixed within the first annular sidewall. At the center of the first annular sidewall, the flow channel plate body extends a cylindrical first fixing post axially. The decoupling membrane has a first through hole at its center that engages with the first fixing post. The first fixing post extends axially to form a second fixing post with a smaller diameter. The flow channel cover plate engages with the second fixing post through the second through hole in its center and is fixed by a riveting process. This restricts the circumferential movement of the decoupling membrane and the axial and circumferential movement of the flow channel cover plate, reducing the risk of component loosening.

[0004] However, the closest existing technology still has significant drawbacks in practical applications: its first fixing post for positioning the decoupling membrane has a fixed size and cannot be adaptively adjusted according to the through-hole size of the decoupling membrane. Because different vehicle models and hydraulic suspensions under different operating conditions have different requirements for the elastic performance and structural strength of the decoupling membrane, the corresponding through-hole size of the decoupling membrane will also be adjusted according to design requirements. The fixed-size first fixing post is difficult to form a suitable assembly relationship with the through-holes of various decoupling membrane specifications.

[0005] When the through-hole size of the decoupling membrane is slightly larger than the diameter of the first fixing post, an assembly gap is easily generated between the first fixing post and the first through-hole of the decoupling membrane, causing the decoupling membrane to become loose and unable to effectively restrict its circumferential movement. Under long-term use, the wear of the decoupling membrane will be aggravated under vibration load. When the through-hole size of the decoupling membrane is slightly smaller than the diameter of the first fixing post, it will result in excessive assembly resistance, which will not only increase the assembly difficulty, but may also cause stress concentration at the edge of the first through-hole of the decoupling membrane, causing the decoupling membrane to break, thereby affecting the sealing performance of the hydraulic mount, and ultimately leading to the failure and scrapping of the hydraulic mount. Utility Model Content

[0006] To solve the above-mentioned technical problems, an improved structure of a high-performance hydraulically suspended flow channel plate is provided, which solves the problems existing in the prior art described in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an improved structure of a high-performance hydraulic suspension flow channel plate, the suspension flow channel plate including a flow channel plate body, the flow channel plate body extending axially to form an annular sidewall, a columnar first fixed column extending axially at the center of the annular sidewall, the first fixed column extending axially to a columnar second fixed column, a plurality of abutment plates surrounding the outer periphery of the first fixed column, the interior of the first fixed column being a cavity, the cavity containing an opening and closing structure for synchronously acting the expansion and closing movements of the plurality of abutment plates.

[0008] Preferably, the opening and closing structure includes a movable disk that can be rotatably assembled in the cavity of the first fixed column, and a plurality of guide grooves evenly opened on the outer peripheral wall of the movable disk. A push-pull block is vertically fixed on one end face of the support plate facing the first fixed column. A plurality of radially penetrating guide holes are opened on the side wall of the first fixed column corresponding to the plurality of push-pull blocks. The end of the push-pull block away from the support plate slides into the corresponding guide hole and forms a sliding fit connection with the guide groove.

[0009] Preferably, the push-pull block has a C-shaped notch at one end of the inner cavity of the first fixed column, the outer edge of the movable disk is located in the C-shaped notch, and a sliding column is vertically fixed in the C-shaped notch, the sliding column sliding in the guide groove.

[0010] Preferably, the bottom surface of the flow channel plate body is provided with a hidden groove, the bottom end of the movable plate is vertically fixed with a rotating rod, the bottom end of the rotating rod rotates into the hidden groove and is fixed with a torsion block, and there is a gap between the torsion block and the inner wall of the hidden groove.

[0011] Compared with the prior art, the advantages of this utility model are as follows: by setting the support plate and the tensioning structure, the outer periphery of the first fixed column can be adapted to decoupling membranes with different through-hole specifications. When there are differences in the through-hole size of the decoupling membrane, by driving the tensioning structure in the cavity, several support plates can be driven to expand outward or contract inward along the radial direction of the first fixed column, thereby adjusting the actual fit size of the outer periphery of the first fixed column, realizing a close fit with decoupling membranes with different through-hole sizes, and effectively solving the problem that the fixed-size column in the prior art cannot adapt to multiple decoupling membranes.

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] Reference Figure 1-3 As shown, an improved structure of a high-performance hydraulic suspension flow channel plate is provided. The suspension flow channel plate includes a flow channel plate body 1, which extends axially to form an annular sidewall 2. A columnar first fixing post 3 extends axially from the center of the annular sidewall 2, and a columnar second fixing post 4 extends axially from the first fixing post 3.

[0019] Referring to the existing technology patent announcement number CN213451478U, entitled "Hydraulic Suspension Flow Channel Plate Device, Hydraulic Suspension Assembly and Automobile", it can be seen that the flow channel plate device achieves the positioning of the decoupling membrane by cooperating with the central through hole of the decoupling membrane through the annular sidewall 2, and then assembles with the through hole of the flow channel cover plate through the first fixing post 3. The flow channel plate body 1, the decoupling membrane and the flow channel cover plate are fixed by the riveting process, thereby forming the flow channel plate assembly of the hydraulic suspension.

[0020] Furthermore, referring to Figure 2 and Figure 3 As shown, it is worth noting that the outer periphery of the first fixed column 3 is surrounded by several support plates 5, and the interior of the first fixed column 3 is a cavity, which contains an opening and closing structure for synchronously expanding and closing the several support plates 5.

[0021] By setting the support plate 5 and the tensioning structure, the outer periphery of the first fixed column 3 can be adapted to decoupling membranes with different through-hole specifications. When there are differences in the through-hole size of the decoupling membrane, by driving the tensioning structure in the cavity, several support plates 5 can be driven to expand outward or contract inward along the radial direction of the first fixed column 3, thereby adjusting the actual fit size of the outer periphery of the first fixed column 3, achieving a close fit with decoupling membranes with different through-hole sizes, and effectively solving the problem that fixed-size columns in the prior art cannot adapt to multiple decoupling membranes.

[0022] Furthermore, referring to Figure 3 As shown, it is worth noting that the opening and closing structure includes a movable disk 12 that can be rotatably assembled in the cavity of the first fixed column 3, and a number of guide grooves 7 evenly opened on the outer peripheral wall of the movable disk 12. A push-pull block 6 is vertically fixed on one end face of the support plate 5 facing the first fixed column 3. A number of radially penetrating guide holes are opened on the side wall of the first fixed column 3 corresponding to the push-pull blocks 6. The end of the push-pull block 6 away from the support plate 5 slides into the corresponding guide hole and forms a sliding fit connection with the guide groove 7.

[0023] By setting the tension and opening structure, the flexible adjustment of the outer peripheral size of the first fixed post 3 is achieved: when it is necessary to adapt to decoupling membranes with different through hole sizes, it is only necessary to drive the movable disk 12 to rotate circumferentially in the cavity of the first fixed post 3. Several guide grooves 7 on its outer periphery will simultaneously generate radial guiding force on the corresponding push-pull block 6, causing the push-pull block 6 to slide smoothly along the guide hole on the side wall of the first fixed post 3, thereby driving several support plates 5 to expand or contract radially along the first fixed post 3, and finally adjusting the actual adapting diameter of the outer periphery of the first fixed post 3 to ensure a tight fit with the through holes of decoupling membranes of different specifications.

[0024] Furthermore, referring to Figure 3 As shown, it is worth noting that the push-pull block 6 has a C-shaped notch at one end of the inner cavity of the first fixed column 3, the outer edge of the movable disk 12 is located in the C-shaped notch, and a sliding column 8 is vertically fixed in the C-shaped notch, and the sliding column 8 slides in the guide groove 7.

[0025] By setting the sliding column 8, on the one hand, a stable connection between the push-pull block 6 and the movable plate 12 is achieved. The sliding column 8 is vertically fixed in the U-shaped notch of the push-pull block 6, and the outer edge of the movable plate 12 is engaged in the U-shaped notch, so that the push-pull block 6 and the movable plate 12 form a limiting assembly, avoiding relative separation and ensuring transmission stability. On the other hand, the sliding column 8 and the guide groove 7 on the outer periphery of the movable plate 12 form a precise sliding fit, which converts the circumferential rotation of the movable plate 12 into the sliding of the sliding column 8 along the guide groove 7, thereby smoothly driving the push-pull block 6 to move radially along the guide hole, and driving the support plate 5 to expand or contract synchronously.

[0026] Furthermore, referring to Figure 3 As shown, it is worth noting that a hidden groove 9 is provided on the bottom surface of the flow channel plate body 1, and a rotating rod 11 is vertically fixed at the bottom end of the movable plate 12. The bottom end of the rotating rod 11 rotates into the hidden groove 9 and is fixed with a torsion block 10. There is a gap between the torsion block 10 and the inner wall of the hidden groove 9.

[0027] By setting up the hidden groove 9 and the torsion block 10, firstly, the hidden groove 9 realizes the embedded installation of the rotating rod 11 and the torsion block 10, so that the transmission structure is not exposed and the flatness of the bottom surface of the annular sidewall 2 is guaranteed; secondly, the torsion block 10 provides a convenient drive operation end for the opening and closing structure. The operator can drive the movable disk 12 to rotate precisely in the circumference by rotating the rotating rod 11 by rotating the torsion block 10, which reduces the difficulty of adaptation and adjustment.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
