Set is external to be equipped with annular sleeve.
As a kind of optimal technical scheme of the utility model, the positioning sleeve inner sleeve and positioning sleeve housing are metal material
Matter.
As a kind of optimal technical scheme of the utility model, the convex block is hemispherical.
As a kind of optimal technical scheme of the utility model, the annular sleeve is hinged on outside positioning sleeve and puts on.
As a kind of optimal technical scheme of the utility model, first retaining ring is oppositely arranged with the second retaining ring.
Compared with prior art, the utility model has the beneficial effects that：This kind of rail vehicle truck elastic locating sleeve,
The first retaining ring and the second retaining ring is respectively set by covering outside positioning sleeve inner sleeve and limit, can prevent rubber layer from axially falling off,
By the way that multiple convex blocks are arranged in positioning sleeve jacket internal and positioning sleeve outside of inner cover, positioning sleeve housing and positioning sleeve inner sleeve can be increased
With the contact area of rubber layer, keep positioning sleeve housing and positioning sleeve inner sleeve and rubber layer vulcanization consolidation stronger, while may be used also
Annular sleeve is arranged by covering outside positioning sleeve in the relative position for limiting positioning sleeve housing and positioning sleeve inner sleeve and rubber layer, can
Facilitate and multiple elastic locating sleeves are serially connected, facilitate the carrying of elastic locating sleeve, by the way that spring shape is arranged in rubber layer
Reinforcing rib, the radial direction that rubber layer can be improved and axis are to intensity, and rationally, greatly improve elastic locating sleeve uses the longevity for design
Life.
Detailed description of the invention

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment, based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of rail vehicle truck elastic locating sleeve,
Including positioning sleeve inner sleeve 1, rubber layer 2 and positioning sleeve housing 3,1 outside both ends of positioning sleeve inner sleeve are equipped with the first retaining ring 4, position
Set 3 inside both ends of housing, which are equipped with, is equipped with the second retaining ring 5, and the first retaining ring 4 and the second retaining ring 5 can limit 2 position of rubber layer, prevent
Rubber layer 2 is axial to fall off, and is equipped with multiple convex blocks 6 inside 1 outside of positioning sleeve inner sleeve and positioning sleeve housing 3, it is fixed to increase respectively
The contact area of position set inner sleeve 1 and positioning sleeve housing and rubber layer 2, while can also limit the position of rubber layer 2, thus make thus
Vulcanize positioning sleeve inner sleeve 1 and positioning sleeve housing 3 with rubber layer 2 and consolidates stronger, positioning sleeve housing 3 and positioning sleeve inner sleeve 1
It is solid integral by the vulcanization of rubber of rubber layer 2, spring shape reinforcing rib 7 is in axial direction equipped in rubber layer 2, spring shape adds
