Abstract
The invention discloses a lifting lug which is used for lifting a second component on a first component. The lifting lug comprises a metal framework and an elastic rubber block fixed in the metal framework. A first installation hole connected with the first component is formed in the upper portion of the elastic rubber block, a second installation hole connected with the second component is formed in the lower portion of the elastic rubber block, a cavity penetrating through the front and the back of the elastic rubber block is formed in the middle of the elastic rubber block, and a vertical spoke is arranged in the cavity and connected with the upper cavity wall and the lower cavity wall of the cavity. The lifting lug has the main advantages of keeping good damping performance, having stable work characteristics in various work conditions and improving work reliability. The lifting lug can serve as a device for connecting a gas exhausting pipe with a car body in a car gas exhausting system, has stable work performance in various work conditions and can guarantee good car NVH performance and good car reliability.
Description
Technical field
The present invention relates to a kind of lifting connection structure.
Background technology
Hanger uses at the frequent cup of engineering goods as the attaching parts that connects two parts.For some, environmental degree of comfort is required to high product, in requiring hanger to meet basic lifting stability, also require to there is reduction noise, reduce the characteristics such as vibration.
For example, the hanger using in automobile exhaust system, it is a device that connects freeing pipe and car body, its noise and vibration to automobile has a certain impact.Along with the raising that people require the traveling comfort of automobile, just require the hanger that freeing pipe is installed should possess good damping behavior, require again under various operating modes, to possess stable serviceability, ensure good NVH performance and reliability.
Hanger conventional on automobile is all made up of metallic framework and the elastic block rubber being fixed in metallic framework, the mounting hole being connected with car body is arranged at elastic block rubber top, the mounting hole being connected with freeing pipe is arranged at bottom, there is cavity at the middle part of elastic block rubber, has two kinds of versions in cavity: one is in cavity, not design spoke, only has a cavity, cushioning performance is good like this, but elastic block rubber is easily out of shape, cause freeing pipe and its Surrounding Parts to be interfered, or the drawing crack of hanger shape-changing cup; The second is in cavity, to be designed with a horizontal spoke, connects the two side of cavity, and spoke is divided into again upper and lower two cavitys cavity, increased like this intensity of rubber block, but because each cavity is less, cushioning performance is than there is no the poor of spoke.
Summary of the invention
The present invention is directed to the problems referred to above, propose a kind of novel shackle structure, in it has better cushioning performance in guarantee, ensure that again it is not easy distortion, but also can prevent that it from excessively being stretched, ensure the reliability of its work.
The technical scheme that the above goal of the invention of the present invention adopts is:
A kind of hanger, it is for being lifted on first component by second component, it comprises metallic framework and be fixed on the elastic block rubber in metallic framework, and the first mounting hole being connected with first component is arranged at described elastic block rubber top, and the second mounting hole being connected with second component is arranged at bottom.Its improvement is: there is the cavity before and after a perforation at the middle part of described elastic block rubber, is provided with a vertical spoke in cavity, connects cavity upper and lower surface chamber wall.Hanger of the present invention adopts vertical spoke to connect in the cavity at rubber block middle part, remains the large cavity of a connection in the middle of elastic block rubber, does not have dividedly, and having like this horizontal partition is that two little cavitys have better cushioning performance.
Further preferably mode is: spoke is and tilts forward and back layout in cavity, and one end is connected to the upper of cavity or cavity of resorption wall by hanger back position, and the other end is the oblique cavity that runs through, is connected to the lower of cavity or epicoele wall by hanger anterior locations.Such layout, because spoke is not completely vertical, has certain gradient, make like this elastic block rubber there is certain degree of being stretched, but be not easy excessively to be stretched, make the hanger can be with a stable performance job, the hanger of the horizontal spoke of intensity ratio is better.
The design of further optimizing is again: between the top and bottom of elastic block rubber and metallic framework, be reserved with respectively cavity.This is to consider under some limit road conditions, as jolt road and some are compared with under thermal environment, hanger is stressed excessive, and thermal deformation is also larger, and hanger is in a kind of ultimate elongation situation, easily cause hanger to pull even drawing crack, now hanger fits together by tensile deformation and the reserved cavity body of metallic framework, gives hanger an anti-bearing force by metallic framework, stops hanger excessively to stretch, maintain hanger normal working, improved the functional reliability of hanger.
From above structural analysis, hanger of the present invention has following characteristics: cushioning performance is good, and the distortion of elastic block rubber is little, and stable performance under various working environments can prevent that hanger from excessively stretching, good reliability.The present invention as the device that connects freeing pipe and car body, can possess stable serviceability in automobile exhaust system under various operating modes, ensures good NVH performance and the reliability of automobile.

1-elastic block rubber; The 2-the first mounting hole, the 5-the second mounting hole; 3-spoke; 4-cavity; 7-upper plenum; 8-lower cavity; 6-metallic framework.
Detailed description of the invention
Below, the invention will be further described by reference to the accompanying drawings:
In figure, show for connecting the shackle structure of automobile exhaust pipe and car body, the hanger monnolithic case bulk that assumes diamond in shape, small in ends up and down, broad in the middle, this structure is the good stability of tool both, saves again material.
Referring to Fig. 1 and Fig. 2, hanger is to be sulfided into one by elastic block rubber 1 outside with metallic framework 6 to form.Metallic framework 6 can adopt the bonding jumper bending with certain width to make.The first mounting hole is arranged at the top of elastic block rubber 1, and the second mounting hole is arranged at bottom, be symmetrical arranged up and down, and line of centers is parallel, and hanger is connected with vehicle body and freeing pipe by two mounting holes.There is a large cavity 4 in the middle part of elastic block rubber 1, has before a vertical spoke 3 is through to from the hanger back side in the middle of cavity.Concrete visible, spoke 3 in cavity by after layouts that turn forward, the cavity of resorption wall that lower end of spoke is connected to cavity leans on the position at the hanger back side, upper end is the oblique cavity that runs through, the epicoele wall that is connected to cavity leans on hanger anterior locations.Can certainly arrange conversely, reach same effect.Spoke thickness 8-10mm, width 15-20mm is optimum.In addition, between the top and bottom of elastic block rubber 1 and metallic framework, be reserved with respectively upper plenum 7 and lower cavity 8, be that elastic block rubber 1 does not fill up the interior space of metallic framework, for the distortion of elastic block rubber 1 reserves certain space, can limit by metallic framework again, make its distortion unlikely excessive.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
