Embodiment
In order to be apparent from the implementation process of the present invention and implementation result, below with reference to accompanying drawing
The present invention will be described in detail.
A kind of small rail car suspension, as shown in figure 1, including small box body 100, walking
Device 200 and running gear 300, running gear 200 is identical with the structure of running gear 300,
Connected by ball link 400.The body of small railway carriage 100 is hung by former and later two damping devices
In the lower section of the running gear 200,300, the running gear sets in orbit；Institute
1-2 passenger can be accommodated by stating small box body, be connected by sus-pension with the running gear.
Running gear walking is in orbit, and the track is narrow many micro- for traditional rail
Rail, track are suspended on ground by bridge joint mode and set.Former and later two described damping devices with
In the connection in carriage walking direction, one is fixedly connected with small box body, another and small railway carriage
Body phase is to being slidably connected.It is described to connect running gear, ball link, former and later two dampings by front and rear
The suspension of device and dolly composition, dolly is set to have certain caching adjustment in fore-and-aft direction
Space, during crooked-running or speed adjust, dolly can keep certain steady.
Specifically, as shown in Fig. 2 the damping device includes shell body 1, central shaft 2,
Shell body 1 is enclosed on the outside of central shaft 2；As shown in Figure 3 and Figure 4, also comprising spring 4, institute
State sheathed spring 4 on central shaft 2 and be arranged in the shell body 1, the one of the spring 4
End abuts the outside bulge 6 on central shaft 2, the inner bulge 11 on other end abutting shell body,
When 4 forced compression of spring, central shaft 2 moves down relative to shell body 1, when spring is released
When bleeding off pressure power, central shaft 2 moves up relative to shell body 1.
The shell body 1 is respectively used to be connected small box body or walking mechanism with central shaft 2,
When the center axis connection small box body, the shell body connects running gear；It is optional another
A kind of connected mode, when central shaft connects running gear, the shell body connects small box body.
In the present embodiment, shell body 1 connects running gear, and central shaft 2 connects small box body,
The lower end setting inner bulge 11 of the shell body 1, the upper end setting of the central shaft 2 are outer
Protuberance 6, the inner bulge 11 are the edge that the lower end of shell body 2 is inwardly collapsed；It is described
Outside bulge 6 is the steel ring or nut being fixedly connected with the upper end of central shaft 2.Spring 4 is set
Between inner bulge 11 and outside bulge 6, the lower section of central shaft 2 sets spacing preiection 21,
The ultimate range moved up for limiting central shaft 2 relative to shell body 1.
In order that the dolly is in the process of walking, central shaft 2 keeps concentric with shell body 1,
The life-span of central shaft and the life-span of motor are protected, elastic ring 5, bullet are set in the shell body
Property ring 5 internal diameter it is suitable with the external diameter of central shaft 2, the external diameter of elastic ring 5 and shell body 1
Internal diameter is suitable.The elastic ring is optionally rubber ring.The elastic ring 5 is at least one,
Can be two or more, in the present embodiment, elastic ring 5 is provided with 2, sets respectively
In the position of the top and bottom of close shell body, and abutted with the both ends of spring 4, elastic ring
5 absorb lateral vibration, improve the comfortableness of seating, right when railway carriage is by side force
The lateral shearing force of suspended axle is reduced, and improves the intensity of central shaft.
In order that central shaft 2 is connected with the top of small box body 100, the lower end of central shaft 2 is set
