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. Specifically, the novel suspension system noise damping sheet is characterized by comprising a plate 11 and a bend 14, wherein the plate 11 and the bend 14 can be machined on the same sheet metal material. The plate 11 is provided with a first connecting hole 13 and a plurality of holes 12, and the edges of the upper surface and the lower surface of the plate 11 of each hole 12 are provided with protrusions. The first connecting hole 13 corresponds to a second connecting hole 21 of the connecting member for a bolt or other connecting member to pass through, and is generally set slightly smaller than the size of the second connecting hole 21. The hole grooves 12 can be formed into through holes or grooves, so that the processing and the manufacturing are convenient, the effect similar to a noise elimination structure can be achieved, the space formed after the connection can be favorable for storing grease, the dry grinding phenomenon between contact surfaces is avoided, and the mechanical abrasion is effectively avoided. The plate member 11 is typically a flat sheet of material having a relatively small thickness, and the projections are small-sized projections that rise in the thickness direction. The bend 14 is connected with the plate 11 and is positioned at the edge of the first connecting hole 13, and a latch 15 is arranged on the outer side surface of the bend 14. The latch 15 is generally provided at a distance from the lower surface of the bend 14 corresponding to the thickness of the coupling member, and the distance of the outermost turn is greater than the second coupling hole 21 of the coupling member.

Further, the protrusion at the edge of the hole groove 12 is a flanging, which can enhance the strength of the hole groove 12 and is convenient to process and generate, and meanwhile, the flange has a good mechanical structure and can be used for buffering.

Further, the plate member 11 has a ring-shaped configuration, generally circular, with the hole 12 being disposed between the inner ring and the outer ring, and the first connection hole 13 forming the inner ring in the middle.

Furthermore, the plate 11 and the bend 14 are made of spring steel, so that the mechanical performance of the plate can be improved while the processing cost is further prevented from being too high.

Furthermore, the latch 15 of each bend 14 has a wedge-shaped structure, and a triangular structure as viewed from the side. The thicker end of each clamping block 15 faces the first connecting hole 13 and is used for abutting against the bottom of the connecting part to form self locking, so that the axial movement of the silencing sheet of the novel suspension system is avoided.

Furthermore, the height of the bend 14 is 0-10 mm, and the height refers to the length of the bend 14 extending relative to the lower surface of the plate 11, which is designed according to the thickness of a common connecting part, so that the practicability can be ensured, and other performances can be prevented from being influenced. The height of the fixture block 15 is 0-2 mm, and the height refers to the thickness of the thickest position. The height of the bulge is 0-1 mm, and the bulge can be effectively filled corresponding to a common gap at the joint.

Further, the holes 12 are uniformly distributed around the first connecting hole 13, so that the stress can be effectively distributed, and the service performance of the holes is ensured, so that the holes can sufficiently deal with the large acting force of the suspension system and the vehicle body connection.

Further, the number of bends 14 is at least 2, which allows for a better force and provides a certain radial limitation.

In the present embodiment, the number of the bends 14 is 3, and each hole 12 is divided into two groups having different radial distances and uniformly distributed in the circumferential direction. The plate 11 and the bend 14 are of an integral structure and are both high strength spring steel. The hole groove 12 is a through hole, and the circular through hole can generate edge protrusion at the same time of generation, namely, flanging is formed.

In use, when the novel suspension system silencing sheet is installed on a suspension system, the first connecting hole 13 of the novel suspension system silencing sheet corresponds to the second connecting hole 21 on the connecting part. After the bend 14 is deeply inserted, the bend 14 is pressed inwards due to elasticity, and after the bend 14 exceeds the fixture block 15, the bend 14 returns to be opened outwards, and the fixture block 15 is abutted against the connecting part at this time. At the moment, the bulge on the lower surface of the silencing sheet of the novel suspension system props against the upper surface of the lower connecting part, and the axle centers of the first connecting hole 13 and the second connecting hole 21 are superposed and used for connecting pieces such as bolts. When the suspension system is connected, the bulge on the upper surface of the noise reduction plate of the novel suspension system is abutted against the lower surface of the upper connecting part. At this time, under the effect of connecting pieces such as bolts, the generated axial force enables the deformation of the opposite surfaces of the two connecting parts, and the bulges on the silencing sheet of the novel suspension system are slightly embedded into the opposite surfaces of the two connecting parts. When there is a tendency for relative sliding in the circumferential direction, its relatively large friction will prevent it from sliding. When there is a tendency for relative radial sliding to occur, the projections on the noise damping plate of the novel suspension system are also resisted by relatively large frictional forces, and the bend 14 is also acted upon with a certain force. There is some elastic cushioning of the protrusion from the surface of the connecting member when there is a tendency for relative axial sliding to occur. The sliding is avoided from three moving directions, and the generation of abnormal sound is effectively avoided. Meanwhile, the design of the hole groove 12 can provide a large retention space for grease, mechanical damage caused by dry friction is avoided, abrasion and abnormal sound are greatly reduced, the shock absorber can respond to impact force in a large mode, and the performance of the novel suspension system silencing sheet is further improved.

In summary, the plate 11 of the present invention is provided with the plurality of holes 12, and the protrusions on the upper surface and the lower surface of the edge of the hole 12 can effectively hold the upper surface and the lower surface of the suspension system, so as to effectively increase the friction force, reduce the sliding, and avoid the occurrence of abnormal noise, and generally, the hole 12 can effectively retain the grease while ensuring the locking, thereby avoiding the dry abrasion. And when the second connecting hole 21 of the bending 14 for connecting part is aligned with the first connecting hole 13, the bending 14 goes deep into the second connecting hole 21, and the fixture block 15 abuts against the second connecting hole 21, so that the novel suspension system silencing piece can be locked on the connecting part, unnecessary circumferential movement is avoided, dislocation of installation can be effectively positioned and avoided, and accuracy is ensured. Furthermore, the bulge at the edge of the hole groove 12 is a flanging, so that the production and processing technology can be effectively simplified, the elasticity of the flanging can provide buffer to a certain degree in the axial direction, so that the jumping and the vibration are avoided, when the flanging eats the surface of the connecting part, the radial stress can be well shared in the sliding process, and the automatic homing of the flanging is fully ensured. Further, the material of body is the spring steel, can promote its performance when guaranteeing that manufacturing cost technology requires lowly, makes the result of use of this novel suspension system amortization piece better.
