[0002] In the process of automobile development, as drivers have higher and higher requirements for automobile use experience, the quality of automobiles must also be improved. When the existing automobile bushing is subjected to increased force, the outer tube and inner tube of the bushing will be subjected to a larger angle load force, causing the outer tube and inner tube to contact the boundary of the car body, generating abnormal noise, and affecting the driving experience. Utility Model Content

[0003] The utility model aims to provide a novel flanged bushing structure to solve the problem of abnormal noise generated by the outer tube and inner tube of the bushing and the boundary of the vehicle body, thereby improving the driving experience of the car.

A second outer tube is added to wrap the exposed part of the inner tube in the prior art to avoid collision with the vehicle body boundary under the action of external force and produce abnormal noise, and at the same time, the buffer structure is arranged to further solve the problem of abnormal noise caused by contact between the bushing structure and the vehicle body boundary under a large angle load force.

[0005] Furthermore, a first rubber layer is provided between the first outer tube and the inner tube, the first rubber layer has a first outer edge whose lower surface contacts the flange of the first outer tube, and the buffer structure is provided on the outwardly facing surface of the first outer edge.

[0006] Furthermore, a second rubber layer is provided between the second outer tube and the inner tube, the second rubber layer has a second outer edge whose upper surface contacts the flange of the second outer tube, and the buffer structure is provided on the outwardly facing surface of the second outer edge.

[0007] Furthermore, the first outer edge radially extends away from the center of the top surface of the inner tube.

[0008] Furthermore, the second outer edge radially extends away from the center of the bottom surface of the inner tube.

[0009] Furthermore, the buffer structure is made of rubber.

[0010] Furthermore, the buffer structure is an annular structure.

[0011] Furthermore, the buffer structure is a rubber block, which is evenly distributed on the outward-facing surface of the corresponding first outer edge or second outer edge.

[0012] Compared with the prior art, the beneficial effects of the utility model are: 1. A second outer tube is added to wrap the exposed part of the inner tube in the prior art to avoid collision with the vehicle body boundary directly under the action of external force and produce abnormal noise.

[0013] 2. Set up a buffer structure to prevent the two ends of the inner tube from directly contacting the boundary of the vehicle body under a large angle load force, causing abnormal noise. The contact between the buffer structure and the vehicle body can not only reduce the collision force, but also avoid rigid collision because it is made of rubber material, reduce the probability of damage, and increase the service life.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-4As shown, a new type of flanged bushing structure of the utility model includes an inner tube 100 and an outer tube structure sleeved on the outer periphery of the inner tube 100; the outer tube structure includes a first outer tube 200 and a second outer tube 300 located at one end of the first outer tube 200, and the length of the first outer tube 200 and the second outer tube 300 is slightly less than the length of the inner tube 100, because the buffer structure described in detail later has a certain thickness, so as to avoid interference with the installation of the inner tube 100 after the buffer structure is installed; the first outer tube 200 and the second outer tube 300 are both flanged outer tubes, and the flange directions are opposite, that is: the flange of the first outer tube 200 is at the top, and the flange of the second outer tube 300 is at the bottom, and the top and bottom here are based on the upper end and the lower end of the inner tube 100. Specifically, the first outer tube 200 and the second outer tube 300 are fixedly connected. A first rubber layer 400 is embedded between the first outer tube 200 and the inner tube 100. The upper surface of the first rubber layer 400 has a first outer edge 410. The lower surface of the first outer edge 410 is in contact with the upper surface of the flange of the first outer tube 200. The first outer edge 410 extends radially away from the center of the top surface of the inner tube 100. A buffer structure 600 is provided on the upper surface of the first outer edge 410. Specifically, the extension length of the first outer edge 410 is less than or equal to the length of the flange of the first outer tube 200, ensuring that the first outer edge 410 is supported by the flange of the first outer tube 200. The buffer structure is made of elastic material, preferably rubber material, which can be natural rubber or synthetic rubber. The rubber material is a prior art and will not be described here. The buffer structure can be an annular whole fixed on the upper surface of the first outer edge 410; or it can be a plurality of rubber blocks evenly distributed along the circumference of the surface of the first outer edge 410, which can not only play a buffering role, but also save materials and costs. When the bushing body 100 is subjected to a large angle load force, the first outer tube 200 does not directly contact the boundary of the vehicle body, but contacts the boundary of the vehicle body through the buffer structure 600. The material characteristics will not cause abnormal noise, and its elastic effect can provide buffering to avoid damage caused by rigid collision.

[0021] Furthermore, a second rubber layer 500 is embedded between the second outer tube 300 and the inner tube 100, and the second rubber layer 500 has a second outer edge 510, and the second outer edge 510 radially extends away from the center of the bottom surface of the inner tube 100, and a buffer structure 600 is provided on the lower surface of the second outer edge 510. The buffer structure is the same as the buffer structure on the upper surface of the first outer edge 410, and will not be described in detail here.

[0022] During use, the flanged bushing structure is fixed on the suspension system, and the suspension system is fixedly connected to the vehicle body. As a prior art, the suspension system is provided with a connecting portion for installing the flanged bushing structure, and the outer tube structure of the flanged bushing structure is interference fit with the connecting portion. During sudden start, sudden stop, acceleration and braking of the vehicle, when the flanged bushing structure is subjected to a large angle load force, the buffer structures at both ends thereof contact with the boundary of the vehicle body to play a role in buffering and shock absorption, and no abnormal noise occurs, thereby improving the driver's driving comfort, reducing rigid collisions, and increasing the service life of components.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
