Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
From Fig. 1 to Fig. 4, connecting cylinder 11 that this undercarriage includes being installed on body, through connecting cylinder 11 and and its
The rotating shaft 12 being rotationally connected；It is provided with rotation stop proof structure, this rotation stop proof structure bag on one end outside rotating shaft 12 is positioned at connecting cylinder 11
The rocker structure 14 that include the rotary spacing cylinder 13 being fixed in rotating shaft 12, is set in rotating shaft 12 and be arranged on rocker structure
14 and away from the back-moving spring 17 between rotating shaft 12 part of position-limiting drum 13, rotary spacing cylinder 13 with rocker structure 14 adjoiner is
Cam couples；It is hinged with support 15 on the other end outside rotating shaft 12 is positioned at connecting cylinder 11, connects between support 15 and rotating shaft 12
Being connected to buffer structure 16, this buffer structure 16 includes that one end first set fitting hinged with rotating shaft 12, one end are hinged with support 15
The second Coupling, first set fitting and the socket of the second Coupling, the outer sheath at first set fitting, the second Coupling is provided with even
T-Ring 163, is provided with the first buffer spring 164 connecting between ring 163 and the hinged end of first set fitting, connect ring 163 with
The second buffer spring 165, the first buffer spring 164 and the second buffer spring 165 it is provided with between the hinged end of the second Coupling
Ultimate load is different.
As shown in Figure 2, rotary spacing cylinder 13 includes the mounting cylinder 131 being set in rotating shaft 12, at the sidewall of mounting cylinder 131
Be provided with window 132, window 132 relative be respectively provided on two sides with engaging lug 133, in the both sides that mounting cylinder 131 end is relative
It is respectively equipped with the connecting plate 135 arranged at a projection 134, and corresponding window 132, in the company of connecting plate 135 with respective side
It is provided with fastening connection piece, by engaging lug 133, connecting plate 135 and fastening connection piece by rotary spacing cylinder 13 between lug 133
Being fixed in rotating shaft 12, in the present embodiment, fastening connection piece generally selects bolt.
From the figure 3, it may be seen that rocker structure 14 includes the rotating cylinder 141 being set in rotating shaft 12, the lateral wall of rotating cylinder 141 connects
