When the first mounting seat 332 moves up and down along with the wheel 2, the first boss 511 also moves up and down, and the up-down displacement of the first boss 511 is converted into the compression or tension of the spring body 531, so that the impact force is absorbed. Further, in order to enhance the buffering effect of the buffering mechanism 5, two buffering springs 53 are provided, and the two buffering springs 53 are respectively provided at two sides of the first boss 511, so that the buffering effect of the whole buffering mechanism 5 is enhanced.

In order to protect the buffer spring 53, prevent the compression amount and the extension amount of the buffer spring from exceeding the allowable values, and simultaneously prevent the wheel 2 from being in hard contact with the vehicle body 1 due to the excessive up-down bumping degree under the limit working conditions (such as excessive gradient and excessive uneven ground), the buffer mechanism 5 further comprises a first stop block 56 and a second stop block. The first stopping block 56 is optionally disposed on the top of the first connecting seat 51, and when the wheel 2 drives the first connecting seat 51 to move upward until the first stopping block 56 abuts against the mounting platform 14, the first connecting seat 51 stops moving upward, and the connecting rod 541 cannot swing continuously. Alternatively, the first stop block 56 may be provided on the lower surface of the mount table 14 of the vehicle body 1, and the link 541 swings to the limit when the first joint socket 51 moves up to abut against the first stop block 56. Similarly, the second stop block may be optionally disposed at the lower portion of the first connecting base 51 or directly disposed on the vehicle bottom plate 12. Optionally, a second stop block is arranged on the lower surface of the first boss 511, and reaches a limit position when the second stop block abuts against the vehicle bottom plate 12; when the second stopper is provided on the floor 12, the first boss 511 reaches the limit position when abutting against the second stopper, and the link 541 stops swinging at the limit position.

Optionally, the second connecting seat 52 includes two support plates 522 parallel to each other and spaced apart from each other, a top plate 523 is further disposed above the two support plates, and the second boss 521 is disposed on the top plate 523 and protrudes toward the side of the wheel 2. During installation, the top plate 523 is fixedly connected to the installation plate 141 of the installation table 14, and the link 541 is rotatably provided on the support plate 522.

The buffer gear 5 that this embodiment provided realizes the buffering of the wheel 2 impact force when jolting from top to bottom, has avoided mount table 14 and automobile body 1 whole to take place large amplitude vibration, has also avoided the article that fork tooth mechanism 3 lifted to take place to rock, has improved fork truck formula IGV vehicle operation's stability.
