It falls, vehicle below and roadside pedestrian can be caused serious injury, formation is great compared with major break down, has major safety risks.
Utility model content
To solve technical problem present in background technique, the utility model proposes one kind, and there is anti-drop structure power to inhale
Shake device.
The utility model proposes one kind there is anti-drop structure dynamic vibration absorber, including inner sleeve, outer tube, rubber master
Body and mass block；
Outer tube is with being located in outside inner sleeve, and body of rubber is between inner sleeve and outer tube and with inner sleeve and outside
Casing vulcanization connection, mass block coaxial cooperation is in outer jacket exterior；
Body of rubber extends to form the first protrusion to mass block side, and mass block extends to form second to body of rubber side
Protrusion, the first protrusion and the second protrusion are ipsilateral positioned at outer tube, and the first protrusion and the second protrusion are perpendicular to inner sleeve length of tube side
To plane on projection have lap, first protrusion and second protrusion in interior casing axis direction interval pre-determined distance.
Preferably, housing length of tube is less than inner sleeve length of tube.
Preferably, body of rubber coats inner sleeve completely, and the first raised structure in a ring is simultaneously enclosed in inner sleeve periphery.

Preferably, inner sleeve extends into the first lobed interior.
Preferably, outer tube and mass block are interference fitted.
In the utility model, what is proposed has anti-drop structure dynamic vibration absorber, and the first protrusion and the second protrusion can be with
The effectively displacement of limitation dynamic vibration absorber mass block under limiting condition, improves the high-durability of dynamic vibration absorber, body of rubber
The first protrusion can prevent mass block from falling off after ageing failure, play protection, promote the safety of traveling.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of cross-sectional view with anti-drop structure dynamic vibration absorber.
Specific embodiment
As shown in FIG. 1, FIG. 1 is the utility model proposes a kind of cross-sectional view with anti-drop structure dynamic vibration absorber.
Referring to Fig.1, the utility model proposes one kind there is anti-drop structure dynamic vibration absorber, including inner sleeve 1, housing
Pipe 2, body of rubber 3 and mass block 4；
Inner sleeve 1, outer tube 2 and mass block 4 are cylindrical, and 1 length of inner sleeve is greater than 2 length of outer tube, outer tube 2
With being located in outside inner sleeve 1, body of rubber 3 vulcanizes between inner sleeve 1 and outer tube 2 and with inner sleeve 1 and outer tube 2
Connection, and body of rubber 3 coats 1 outer surface of inner sleeve completely, and the body of rubber 3 between outer tube 2 and inner sleeve 1 is ordered
The body of rubber 3 on 1 surface of inner sleeve is named as the second rubber section by entitled first rubber section, and mass block 4 cooperates in outer tube 2
Outside, the second rubber section interval pre-determined distance of mass block 4 and 1 surface of inner sleeve, the first rubber section and outer tube 2 are by mass block
4 and the second space between rubber section along two sections of the axially spaced formation of mass block 4；
Body of rubber 3 extends to form the first protrusion 31 to 4 side of mass block, and mass block 4 extends shape to 3 side of body of rubber
At the second protrusion 41, the first protrusion 31 and the second protrusion 41 are located in same section, and the second protrusion 41 is located at the first raised 31 Hes
Between first rubber section, the projection tool of the first protrusion 31 and the second protrusion 41 on the plane perpendicular to 1 length direction of inner sleeve
There is lap, the first protrusion 31 and the second protrusion 41 are in 1 axis direction interval pre-determined distance of inner sleeve.
Inner sleeve 1 with extraneous vehicle body for connecting, and mass block 4 is where the first protrusion 31 and the second protrusion 41 after connection
The side in section is opposite with vehicle body, since the first raised 31 and second protrusion 41 is in the plane perpendicular to 1 length direction of inner sleeve
On projection have lap, when first protrusion 31 and second protrusion 41 lean when, mass block 4, which is restricted from, to be continued to move
It is dynamic, so that the first protrusion 31 and the second protrusion 41 can effectively limit the displacement of dynamic vibration absorber mass block 4 under limiting condition,
The high-durability of dynamic vibration absorber is improved, the first protrusion 31 can prevent mass block 4 from falling off after 3 ageing failure of body of rubber, rise
The effect of protection promotes the safety of traveling.
The first protrusion 31 and the second protrusion 41 are ring structure in the present embodiment, are wound on the second rubber outside the first protrusion 31
Portion periphery, the second protrusion 41 are coaxially set with mass block 4.
In the present embodiment, inner sleeve 1 is extended into inside the first protrusion 31, to improve the hardness of the first protrusion 31, is prevented
First protrusion 31 is squeezed that two deformations are excessive to cause the first protrusion 31 to move to second raised 41 other sides by the second protrusion 41, and then is led
The failure of actuating power bump leveller.
In the present embodiment, outer tube 2 and mass block 4 are interference fitted.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
