The force transmission rod 7 includes an upper portion 71 extending upwardly from the upper moving portion 522 of the reaction member 2, and is located between the arm portion 622 and the upper portion of the reaction member 52 after the cantilever rod 62 a lower portion 72, and the first rocker 81 is forwarded by the uploading portion 71 to the upper frame portion 321 of the mast 3, and the second rocker 82 is forwardly connected to the frame by the lower transmitting portion η The rod 3 has a lower portion 322. Since the first and second rocker Η and 82 series are installed between the mast 3 and the force transmission rod 7, the upper and lower setting positions of the first and second rockers 81 and 82 can also be changed, for example, the first (four) can be Move to the lower side of the second rocker 82 or move the second rocker 82 above the first shaker 81, and will not be described in detail herein. The configuration of the third preferred embodiment of the suspension device of the present invention is the same as that of the first embodiment, except that the buffer 9 is between the == moving rod 83 and the cantilever rod 62. Moreover, the linkage rod (4) is between the movable rod (4) and the upper moving portion 522 of the reaction member 52. The force transmitting rod ^ ^ 52 lower moving portion 523 and the cantilever rod 62 after the arm portion 622 2: 1 is extended from the lower moving portion (2) along the long direction thereof, and the second = is located at the rear arm portion 622 and below Between the moving parts 523. In addition, the first and second cases of this example are fine; J圼5^1. The inclination angles of q and 82 are also different from those of the second embodiment 201000359, and of course, the design is not limited to the embodiment. It can be seen from the above description that the suspension device of the present invention utilizes a plurality of rod members to form two parallel four-bar linkage mechanisms that are pivotally linked to each other, thereby buffering the vibration force transmitted to the frame during traveling, and receiving a large shock force. The buffer can still be moderately cushioned, and the suspension device includes the mast 3, the wheel bar 4, the reaction member 52, the cantilever lever 62, the force transmission lever 7, the first rocker 8ι, the second rocker u, and the linkage Eight rods, such as the rod 83, have a large degree of freedom for changing the design. For example, the two parallel rod-linking mechanisms of the two parallel four-bar linkages are not parallel, and the shock absorbing effect can also be achieved. The utility model has the advantages of large design freedom and better maneuverability, and can indeed achieve the object of the present invention. Therefore, the present invention is not only an unprecedented innovation, but also can be utilized in the industry. The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
