Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In order to solve the related technical problems existing in the prior art, the embodiment of the application provides a bushing which is applied to an automobile shock absorber and used for realizing the connection of the shock absorber and two end parts of an automobile body, meanwhile, the strength of the bushing is enhanced, and the service life of the bushing is prolonged. Specifically, as shown in fig. 1-3, the device comprises a profile block 1, a rubber sleeve 2 and a lantern ring 3. The center of the special-shaped block 1 is provided with a central mounting hole 4, and the general central mounting hole 4 is a round hole and used for mounting a connecting piece and is connected with an upper part of a vehicle body through the connecting piece. Of course, the central mounting hole 4 may be rectangular, triangular, etc. for convenience of use, so as to facilitate installation and adapt to the use environment. Most importantly, the central sleeve of the existing shock absorber bushing is replaced by the special-shaped block 1, so that the stress strength between a connecting piece and a stress surface of the bushing on the bushing is increased, and the problems that in the prior art, the contact stress point of a circular sleeve and a rubber sleeve 2 is small, the rubber sleeve 2 is easy to fall off and deform, and the service life is shortened are solved. Specifically, the irregular block 1 at least comprises a supporting surface 5, and the supporting surface 5 faces a supporting force-bearing direction, wherein the supporting force-bearing direction refers to: when the shock absorber plays a buffering role in the using process, the connecting piece plays a role in extruding the bushing. In order to solve the problem that only part of the rubber sleeve 2 is easily damaged due to stress in the prior art, the stress amount of the rubber sleeve 2 needs to be increased, the most direct way is to increase the contact area between the rubber sleeve 2 and the special-shaped block 1, and specifically, the supporting surface 5 is a plane or an arc surface.

In this embodiment, dysmorphism piece 1 overcoat is equipped with lantern ring 3, lantern ring 3 and central mounting hole 4 coaxial, it has rubber sleeve 2 to fill between dysmorphism piece 1 and the lantern ring 3, rubber sleeve 2 all vulcanizes fixedly with dysmorphism piece 1 and lantern ring 3, strengthens the joint strength of 2 inside and outside and dysmorphism pieces 1 and lantern ring 3 of rubber sleeve, causes the tear when preventing to use.

Based on the above structure, the present application provides the following embodiments:

example 1

In this embodiment, as shown in fig. 1, the section of the special-shaped block 1 is rectangular, 4 faces of the rectangular special-shaped block 1 are fixed to the rubber sleeve 2 through vulcanization, and in order to increase the contact area between the rubber sleeve 2 and the special-shaped block 1 in the force-receiving direction, specifically, the face corresponding to the long side of the special-shaped block 1 is the supporting face 5, and the faces corresponding to the short sides are disposed at two ends of the supporting face 5. Therefore, when using, the equal greatly increased of area of contact and atress volume of holding surface 5 and rubber sleeve 2 to strengthened rubber sleeve 2 and received the impact force of connecting piece when assaulting, can strengthen the buffering effect of bush on the one hand, on the other hand can also prolong the life of whole bush.

In order to prevent in the use, the short side and the long limit of the dysmorphism piece 1 of rectangle correspond the junction and form the connection angle, the rectangle 1 four corners of dysmorphism piece is the fillet, prevents effectively that the four corners from tearing rubber sleeve 2 production.

In this embodiment, the shaped block 1 is a metal block, such as a cast iron block, a stainless steel block, or the like. Of course, the irregular block 1 made of other materials can be selected as long as the use requirement can be met.

Example 2

As shown in fig. 2, in order to enhance the buffering performance between the special-shaped block 1 and the rubber sleeve 2 and reduce the performance difference between the special-shaped block 1 and the rubber sleeve 2, specifically, the special-shaped block 1 comprises a central circular tube 6 and a nylon block 7, the nylon block 7 has certain impact resistance and deformability, and can be directly contacted and fixed with the rubber sleeve 2, when in use, the rubber sleeve 2 and the nylon block 7 are deformed by a certain amount, so that the buffering performance of the bushing is improved, and meanwhile, when the nylon block 7 is extruded by a connecting piece, the nylon block 7 can deform by itself, so that the extrusion deformation of the rubber sleeve 2 is slowed down, and the service life is prolonged. The central circular tube 6 is fixedly sleeved at the center of the nylon block 7, and the outer wall of the nylon block 7 is arranged in a smooth mode.

And the mounting structure also comprises a key groove 8, and the key groove 8 is arranged in the central mounting hole 4. When the connecting piece is used, the key matched with the key groove 8 needs to be arranged on the connecting piece, the connecting piece is convenient to mount, the orientation of the supporting surface 5 can be accurately positioned when the bushing and the connecting piece are connected, and the bushing is guaranteed to be mounted in place.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
