[0021] Please see Figure 1-3 A gearbox alloy bracket structure with vibration-damping connection includes an alloy bracket 1. A honeycomb buffer layer 2 is provided at the top of the alloy bracket 1, and high-damping rubber 3 is filled into the honeycomb pores of the honeycomb buffer layer 2. First mounting holes 5 and second mounting holes 6 are respectively provided at both ends of the alloy bracket 1. A third mounting hole 4 is provided in the middle of the alloy bracket 1. The third mounting hole 4, the first mounting hole 5, and the second mounting hole 6 all pass through the honeycomb buffer layer 2. A stacked damping plate 7 is provided at the bottom of the alloy bracket 1. The damping plate 7 is composed of a first aluminum plate 8, a second aluminum plate 10 and a high-damping adhesive 9. The high-damping adhesive 9 is located between the first aluminum plate 8 and the second aluminum plate 10. The top of the first aluminum plate 8 is connected to the bottom of the alloy bracket 1. Both the left and right ends of the first aluminum plate 8 are connected to a first connecting block 11. Both the left and right ends of the first connecting block 11 are connected to the alloy bracket 1 by a first fastening bolt 12. Both the left and right ends of the second aluminum plate 10 are connected to a second connecting block 13. A second fastening bolt 14 is provided on the second connecting block 13.
[0022] The connection between the first fastening bolt 12 and the alloy bracket 1 is a threaded connection.

[0024] The number of second fastening bolts 14 is set to four, and the four second fastening bolts 14 are arranged in pairs opposite to the two second connecting blocks 13.

[0026] The honeycomb buffer layer 2 and the alloy support 1 are bonded together with an adhesive.
[0027] The working principle and usage process of this utility model are as follows: First, during installation, multiple fasteners are passed through the third mounting hole 4, the first mounting hole 5, and the second mounting hole 6 respectively to be fastened to the gearbox. The second fastening bolt 14 passes through the second connecting block 13 and is threaded to the fixed mounting surface of the engine compartment. By setting the honeycomb buffer layer 2 and the high damping rubber 3, the honeycomb structure of the honeycomb buffer layer 2 itself can increase the structural flexibility and damping. The high damping rubber 3 further absorbs vibration energy and converts it into heat energy, significantly improving the damping characteristics of the bracket itself, reducing the radiation and transmission of vibration outward, and thus having a good anti-vibration buffering effect.
[0028] By setting up a stacked damping plate 7, which is composed of a first aluminum plate 8, a second aluminum plate 10 and a high-damping adhesive 9, the first aluminum plate 8 and the second aluminum plate 10 dissipate a large amount of vibration energy through shear deformation of the intermediate high-damping adhesive 9, providing excellent broadband vibration isolation effect.
