Problems solved by technology

This kind of suspension structure is only supported by rubber pads, so its load-bearing capacity is poor, and due to the lack of a limit structure in the horizontal direction, the amount of movement is large, and it is difficult to achieve the ideal vibration reduction effect.

Embodiment 1

[0023] Such as figure 2 As shown, the exhaust system suspension mechanism of this embodiment includes an upper bracket 1 and a lower bracket 8, a main rubber block 3 is arranged between the upper bracket 1 and the lower bracket 8, and the upper bracket 1 and the lower bracket 8 pass through the upper bracket 8 in sequence. Bolts 4 and nuts 7 on the bottom surface of the bracket 1, the main rubber block 3 and the top surface of the lower bracket 8 are connected and fixed.

[0024] When installing and using, the upper bracket 1 is fixed on the vehicle frame or the vehicle body, the lower bracket 8 is connected to the exhaust system, the bolt 4 cooperates with the nut 7 to connect and fix the upper bracket 1 and the lower bracket 8, and the material of the bolt 4 is a rigid material, which can not only The exhaust system used to bear a large weight can also cooperate with the openings of the upper and lower brackets to prevent the horizontal displacement between the lower bracke...

Embodiment 2

[0027] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that an additional rubber block 2 and a gasket 6 are arranged above the bottom surface of the upper bracket 1 of this embodiment, and the bolt 4 passes through the gasket 6, the additional rubber block 2, The bottom surface of the upper bracket 1, the main rubber block 3 and the top surface of the lower bracket 8, and cooperate with the nut 7 to connect and fix the upper bracket 1 and the lower bracket 8. Under the action of the bolt 4 and the nut 7, the additional rubber block 2 is pressed by the gasket 6 and the bottom surface of the upper bracket 1 to produce a certain degree of elasticity, and the additional rubber block 2 cooperates with the main rubber block 3 to fix the bolt 4 and the The up and down displacement of the lower lower bracket 8 below plays a certain role of restriction and buffering, and improves the effect of vertical vibration reduction.

Embodiment 3

[0029] Such as Figure 4 As shown, different from the above-mentioned embodiments 1 and 2, this embodiment sets a sleeve 5 through the main rubber block 3, the bottom surface of the upper bracket 1, the additional rubber block 2 and the top surface of the lower bracket 8, and the bolts 4 pass through the pads in turn. Sheet 6, sleeve 5, and cooperate with nut 7 to connect and fix upper bracket 1 and lower bracket 8. There is a certain gap between the sleeve 5 and the bolt 4, so that the horizontal displacement of the bolt 4 and the lower bracket 8 fixed under the bolt 4 can be independent of the upper bracket 1, thereby reducing the impact on the upper body and improving the ride comfort .

[0030] The length of the sleeve 5 is slightly less than the sum of the height of the additional rubber block 2, the height of the main rubber block 3, the thickness of the bottom surface of the upper support 1, and the thickness of the top surface of the lower support 8. In this way, the...

Abstract

The invention aims at providing an exhaust system hanging mechanism with strong bearing capacity and good damping effect. The exhaust system hanging mechanism comprises an upper bracket (1) and a lower bracket (8); more particularly, a main rubber block (3) is arranged between the upper bracket (1) and the lower bracket (8); and the upper bracket (1) and the lower bracket (8) are connected and fixed with a nut (7) in a coordinating way by passing the bottom surface of the upper bracket (1), the main rubber block (3) and the top surface of the lower bracket (8) in sequence. The exhaust system hanging mechanism has the advantages of simple structure, low cost, strong bearing capacity, and good vibration absorption effect, is suitable for various vehicles, and more particularly is suitable for heavy-typed trucks with heavy loan of exhaust system and bad vibration conditions and the like.

Description

technical field [0001] The invention relates to an exhaust system of an automobile engine, in particular to a hanging mechanism of the exhaust system. Background technique [0002] as attached figure 1 As shown, usually the suspension of the automobile exhaust system is composed of a rubber suspension block and hooks at both ends, and the hooks at both ends are respectively connected to the frame and the exhaust system. This kind of suspension structure is only loaded by rubber pads, so its load-bearing capacity is relatively poor, and because of the lack of a limit structure in the horizontal direction, the amount of movement is large, and it is difficult to achieve an ideal vibration reduction effect. In particular, heavy-duty trucks now widely use diesel engines with large displacement. The exhaust flow rate of the exhaust system is fast and the working conditions are complicated. And other purification devices, so a suspension mechanism that can withstand greater loads...
