When receiving vibrations, the inner ring can rotate in one direction to avoid the inner ring to receive the impact for a long time in a position, thereby can effectively avoid the inner ring to warp, the inner ring does not warp then in case the go-between produces deformation, the inner ring can also play the effect of restoreing the go-between.

The second embodiment is different from the first embodiment in that:
referring to fig. 6, the frame 1 is provided with static support feet 17 and road wheel mounting bars 9. The static supporting feet 17 are connected with the frame 1 through screw threads to realize lifting connection. Static support feet 17 may be adjusted lower than ground wheels 18. The road wheel mounting bar 9 includes a lower section 91 and an upper section 92. Road wheels 18 are attached to the lower end of lower section 91.

Referring to fig. 7, the inner circumferential surface of the rubber ring 7 is provided with a plurality of blind holes 71 distributed along the circumferential direction of the rubber ring (the blind holes may be provided on the outer circumferential surface of the rubber ring). A partition plate 72 is provided in the blind hole 71. The partition plate 72 divides the blind hole 71 into two cavities, i.e., an inner cavity 711 and an outer cavity 712. The open end of the blind hole 71 is capped with a resilient cap 73. The elastic cap 73 has a bowl shape that is arched toward the inside of the blind hole 71.

The friction lever 77 is cylindrical. The friction lever 77 is provided with a branch friction channel 78. The friction channel 78 communicates with the space above and below the friction plate 76 (i.e., communicates with the inner and outer chambers). Both axial end faces 771 of the friction lever 77 are spherical.
Referring to fig. 10, the friction lever 77 is provided with a plurality of grooves 772 on both axial end faces 771 thereof. Grooves 772 are circumferentially distributed along friction bar 77.
The present invention is supported by road wheels 18 when moved. The formwork is supported by static support legs 17 during the fixing construction.
The shock absorption process of the invention to the generated shock comprises the following steps: referring to fig. 7 to 10, when the inner cavity 711 and the outer cavity 712 are filled with liquid (although the present invention may also be made by filling liquid), the panel and the horizontal fixing plate vibrate to squeeze the rubber ring 7, so as to deform the blind hole 71, so that the liquid flows back and forth between the inner cavity 711 and the outer cavity 712, the friction plate 76 and the friction rod 77 (see fig. 10) vibrate, and the vibration energy is converted into heat energy during the liquid flowing and the vibration of the friction plate and the friction rod and is consumed. If the vibration is small and is not enough to cause the deformation of the blind hole, only the liquid shakes, and the friction rod shakes to absorb energy when the liquid shakes.
The third embodiment is different from the second embodiment in that:
referring to fig. 11, the road wheel mounting bar 9 is also provided with a drive mechanism 6. The inner ring 922 is rotatably connected to the rubber ring 7, and the rubber ring 7 is fixed to the connection ring 921.
The drive mechanism 6 includes a ratchet wheel 61, a pawl 62 that drives the ratchet wheel, and a drive lever 63. The ratchet wheel 61 is coaxially coupled with the inner ring 922. The ratchet 61 is integral with the inner ring 922. The pawl 62 is fixedly attached to one end of the drive rod 63. The upper section 92 is provided with a slide hole 924. The other end of the driving rod 63 can be two-dimensionally and slidably inserted into the sliding hole 924. The lower end of the driving rod 63 is slidably hooked to the lower section 91 (see fig. 6) in the radial direction of the connection ring 921. The driving rod 63 is provided with a storage hole 64. There are two storage holes 64. An engagement spring 65 is inserted into the storage hole 64. The engaging spring 65 is a tension spring. The engagement spring 65 has one end connected to the drive rod 63 and the other end connected to the upper section 92. When the engaging spring 65 is in a free state, the pawl 62 can be engaged with the ratchet wheel 61 under the spring action of the engaging spring 65.
In use, when the road wheel mounting rod 9 generates a contraction motion due to a shock, the driving rod 63 translates (i.e. moves upward in the figure) towards the connection ring 921, at this time, the pawl 62 can drive the ratchet wheel 61 to rotate clockwise, the ratchet wheel 61 drives the inner ring 922 to rotate clockwise, when the road wheel mounting rod extends, the driving rod 63 moves downward, at this time, the pawl 62 cannot drive the ratchet wheel 61 to rotate, when the pawl 62 touches teeth on the ratchet wheel 61, the driving rod 63 is away from the ratchet wheel 61 so that the driving rod 63 can reset, and when the pawl 62 does not touch teeth on the ratchet wheel 61, the pawl 62 moves rightward and resets under the action of the meshing spring 65. Therefore, the impact portion of the inner ring 922 is different in each vibration cycle, and the inner ring 922 receives the impact by continuously changing its position in the circumferential direction, and is not easily deformed to become an ellipse.
