[0046] In other embodiments, the connecting rods 114 can be assembled according to other layouts, such as three or more layers, or staggered layouts, etc., as long as the connecting rods 114 arranged between the track beam bodies 111 can increase the size of the track beam body. The transverse connection stiffness of 111 is enough.
[0047] The horizontal vibration and noise reduction device 3a in the above-mentioned implementation one and embodiment two uses rubber blocks, and the vertical vibration and noise reduction device 3b is a vibration reduction support device. According to structural differences, it can be implemented in the following three implementation modes, specifically land:
[0048] Such as Figure 7 As shown, it is a schematic cross-sectional structure diagram of Embodiment 1 of the vibration-damping support device with the function of vibration-damping and noise-reducing decentralized support track structure of the present invention.
[0049] The vibration...
