Referring to fig. 1-5, fig. 1 is a schematic front view, fig. 2 is a schematic back view, fig. 3 is a corresponding schematic view of the mounting structure of the present invention, fig. 4 is a schematic front view of the mounting structure of the present invention, and fig. 5 is a schematic back view of the mounting structure of the present invention. Particularly, the novel metal silencing sheet for the suspension system is generally arranged into an integrated body, so that the novel metal silencing sheet can be conveniently processed and manufactured, and the mechanical property of the novel metal silencing sheet is ensured. The body is generally of sheet metal construction, usually metal, but may be made of other materials. Be equipped with first through-hole 11, arch 12 and hem 13 on the body, the quantity of arch 12 is a plurality of and is the curved surface form, and a plurality of archs 12 distribute in the upside and the downside of body, and hem 13 extends to a lateral bending. The number of the first through holes 11 is not necessarily one, and is mainly for passing the bolt through the connection and locking the position thereof. The size of the first through hole 11 is generally the same as the size of the second through hole 21 of the connection member, ensuring uniformity in connection. The protrusion 12 is generally formed as a smooth curved surface, and when a screw fastener such as a bolt or a screw is sequentially inserted through the first through hole 11 and the second through hole 21, the noise damping sheet is locked to the connection member, and the noise damping sheet is forced so that the protrusion 12 is formed with a mounting groove 22 for receiving the protrusion 12 on the surface of the connection member. And flap 13 is generally directed vertically away from the surface on which the body is located. Which is correspondingly fitted into the mounting hole 23 of the coupling member, and the folded edge 13 is inserted into the mounting hole 23.
Furthermore, the convex 12 is a semi-spherical convex 12, the semi-spherical convex 12 can effectively ensure that the convex 12 is automatically matched when the convex 12 is eaten into the mounting groove 22 of the connecting part, the change of the curvature on the convex can lead the convex to have single and rapid automatic homing, the connecting part of the suspension system can be rapidly homing when the connecting part slides relatively, and abnormal sound is suppressed.
Furthermore, the material of body is the spring steel, can further avoid the processing cost too high simultaneously, improves its mechanical properties. There is a relatively large interaction between the projection 12 and the flange 13 in the connecting member to further lock the position of the body while restricting the sliding movement of the connecting member. The spring steel can ensure the normal use of the spring steel under a larger acting force from the material property, and the practicability and the durability of the use of the spring steel are improved.
Further, the protrusions 12 are distributed around the first through hole 11, so that relative sliding of the protrusions can be limited in multiple directions, and relatively large acting force between the suspension system and the vehicle body can be evenly distributed, and normal operation of the suspension system is guaranteed.
Furthermore, the bending and extending length of the folded edge 13 is 0-10 mm, and the radius of the semi-spherical bulge 12 is 0-3 mm. From practical tests, the size range has better service performance.
Further, the folded edge 13 is arranged at the edge of the body, similarly to directly leaving excess material at the tail end of the sheet metal part, and then directly bending and forming.
Further, each hem 13 is equipped with the round chamfer with the body junction, can avoid the corner that the bending type becomes to the wearing and tearing of connection surface, and then generates some sweeps and leads to further wearing and tearing.
In the embodiment of the present invention, the body is ring-shaped, and 4 protrusions 12 are provided on both the upper and lower sides of the body, and are uniformly distributed along the first through hole 11. Or two pairs of the components can be oppositely arranged. Whereas the number of flaps 13 is 2, the flaps 13 are usually further from the first through hole 11 than the protrusions 12. From the angle of the lever, the allowable force and deformation degree of the folded edge 13 are relatively large, and meanwhile, when the folded edge slides relatively, the sliding of the outer ring is relatively large, so that the relative sliding can be effectively limited. On the whole, the novel metal silencing sheet of the suspension system is designed like a fishtail shape, and is convenient and efficient to mount and use.
In use, when the shock absorber is mounted on a suspension system, the noise reduction sheet is attached to the connecting part, the folded edge 13 is aligned with the mounting hole 23, the first through hole 11 is aligned with the second through hole 21, then threaded fasteners such as bolts or screws sequentially penetrate through the first through hole 11 and the second through hole 21, the noise reduction sheet is locked on the connecting part, and the noise reduction sheet is stressed to enable the protrusion 12 to form a mounting groove 22 for accommodating the protrusion 12 on the surface of the connecting part. The corresponding connecting metal is usually also a plate, and the fold 13 usually extends deeper than the projection 12. In the use process, when radial displacement occurs, the bulge 12 can jack up the connecting metal, so that the force action exists between the connecting pieces, and the force can enable the connecting metal to return along the curved surface, so that the relative sliding and abnormal sound are effectively avoided. Meanwhile, the folded edge 13 is hooked with the connecting metal, so that the radial acting force is effectively buffered, and the connection is ensured. When circumferential displacement occurs, the bulge 12 can jack the connecting metal, the two folded edges 13 have the same function, reverse acting force is generated due to elasticity, the connecting metal is jacked back, and circumferential sliding and possible abnormal sound are effectively avoided. For the axial movement, when the axial connection is not tight enough, the circumferential displacement can easily grow while jumping, so that the bulge 12 is filled in the displacement, the direct collision after the connection is further avoided, and the abnormal sound problem is avoided.
In summary, the curved surface-shaped protrusion 12 provided on the body of the suspension system provided by the embodiment of the invention can be eaten into the connected metal during installation, so as to effectively prevent relative sliding, enhance the axial and circumferential effects of the suspension system during connection, and improve the overall performance while saving the cost. And hem 13 can be packed into the mounting hole 23 in the connecting metal on the body, can effectively play the location and prevent pivoted effect, combines protruding 12 can effectively realize dual location simultaneously, dual spacing effect. Further, the bulge 12 is semicircular, performance effect of eating into connected metal can be improved to a certain extent, axial compression can be further achieved by utilizing the bulge 12 to lift the axial distance, the curved surface can effectively buffer and reduce gaps, and abnormal sound of connection of a suspension system is avoided. Furthermore, the material of body is the spring steel, can guarantee its performance when guaranteeing that manufacturing cost technology requires lowerly, makes this novel suspension system metal amortization piece's result of use better.
