Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the utility model cross section structure schematic diagram.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with specific embodiment
The present invention will be further described in detail.In the description of the present invention, it should be noted that unless otherwise clear
Regulation and restriction, term " installation ", " connected ", " connection " shall be understood in a broad sense, can also be with for example, it may be fixedly connected
It is to be detachably connected, or be integrally connected；It can be mechanical connection, be also possible to be connected directly, intermediary can also be passed through
It is indirectly connected, can be the connection of two components interiors.For the ordinary skill in the art, it can be managed with concrete condition
Solve the concrete meaning of above-mentioned term in the present invention.
As shown in Figure 1, a kind of automobile-used elastic damping structure of track, including shell 1, the shape of shell 1 are cylindrical shape, up and down
Without bottom.Inner casing 2 is mounted in shell 1,2 appearance of inner casing is also a cylinder-like structure, and the cross sectional shape of inner casing 2 is
Concave, concrete analysis constitute 22 structure of inner cavity 21 and exocoel.Shell 1 and inner casing 2 be nested together and between be equipped with gap
3, noise reduction sponge is filled in gap 3, plays fine sound deadening.
For the connection for realizing shell 1 and inner casing 2, it is mounted with that annular slab 4, annular slab 4 are logical in the upper end of inner casing 2 and shell 1
Bolt is crossed to be horizontally fixed on inner casing 2 and shell 1.Annular slab 4 covers gap 3 just, plays good connection function.In inner casing
In 2, it is equipped with spring 5, guide part 1, guide part 27, spring 5 is mounted in exocoel 22, and spring 5 is directly sleeved on the outer of inner cavity 21
On surface, the upper end of spring 5 is fixed on the lower surface of the upper surface a of inner casing 2, and the lower end of spring 5 is fixed on inner casing 2
Bottom b inner surface.The flexible of vertical direction may be implemented in spring 5.Guide part 1 includes ring-shaped platform 61 and guide rod
62, the guide rod 62 is fixedly mounted on the center of ring-shaped platform 61, and 61 diameter of ring-shaped platform is less than the interior of annular slab 4
Diameter, and it is greater than the diameter of inner cavity 21, it is set on ring-shaped platform 61 there are two bolt connection piece 60, the effect of bolt connection piece 60 is
It is fixed on railcar trim panel.Guide rod 62 gos deep into inner cavity 21 and is fixed on the bottom of inner cavity 21.
