Abstract

The utility model discloses a rubber bushing, including the inner tube, outer tube and the rubber body of setting between inner tube and outer tube, waist position is equipped with the bellied spacing wall of outside arc in the outer wall of inner tube, be equipped with annular open slot on the rubber body outer wall, be equipped with the holder in the open slot, the holder includes annular barrel, inner wall epirelief at this barrel is equipped with annular butt piece, butt piece tip is equipped with the arc wall that corresponds with spacing wall, this arc wall is the interval setting with spacing wall, the both ends of barrel and the sealed butt of the open end inner wall of open slot, form sealed chamber between barrel inner wall and the open slot inner wall, it has fluid to fill at this sealed intracavity. Therefore, the technical effects of reliable structure and better damping effect are achieved.

Description

Rubber bushing

Technical Field

The utility model relates to a bush of using in the automobile swing arm, concretely relates to rubber bush.

Background

Rubber bush mainly installs on automobile swing arm, be connected through adapting unit and vehicle chassis, support and shock attenuation buffering are provided for the chassis, improve the travelling comfort that the vehicle was taken, and general rubber bush includes the outer tube, the inner tube and sets up the rubber between outer tube and inner tube, cushion the shock attenuation through the elasticity of rubber, because rubber is the buffering that solid results in the shock attenuation effect limited can not satisfy higher requirement, lead to can not effectively exert the shock attenuation cushioning effect in rubber bears great vibrations.

Disclosure of Invention

In order to solve the problems, the utility model aims to provide a rubber bushing that the structure is reliable and the shock attenuation effect is better.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a rubber bush, includes inner tube, outer tube and the rubber body of setting between inner tube and outer tube, the waist position is equipped with the bellied spacing wall of outside arc in the outer wall of inner tube, the rubber body outer wall on be equipped with annular open slot the open slot in be equipped with the holder, the holder include annular barrel, be equipped with annular butt piece at the inner wall epirelief of this barrel, butt piece tip be equipped with the arc wall that spacing wall corresponds, this arc wall with spacing wall is the interval setting, the both ends of barrel with the sealed butt of open end inner wall of open slot, the barrel inner wall with form sealed chamber between the open slot inner wall, it has fluid to fill in this sealed intracavity.

And the ports at the two ends of the outer pipe are respectively bent inwards and narrowed to form a surrounding edge.

And the outer wall of the cylinder body is also provided with an annular elastic groove.

The utility model discloses a when this kind of structure, vehicle met great vibrations, the fluid of the sealed intracavity of accessible carried out more effectual shock attenuation buffering, and the butt piece on the holder can contact the buffering with the outer wall of inner tube simultaneously, further improved the reliability of structure, prevented the excessive extrusion wearing and tearing of the rubber body, improved life, just so realized reliable and the better technological effect of shock attenuation effect of structure.

The invention is further described with reference to the accompanying drawings and the detailed description.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The present invention will be specifically described below by way of examples.

As shown in fig. 1, the embodiment discloses a rubber bushing, including inner tube 1, outer tube 2 and the rubber body 3 of setting between inner tube 1 and outer tube 2, rubber body 3 is connected with inner tube and outer tube through vulcanizing, waist position is equipped with the bellied spacing wall 11 of outside arc in the outer wall of inner tube 1, be equipped with annular open slot 31 on the outer wall of rubber body 3, be equipped with holder 4 in open slot 31, holder 4 includes annular barrel 41, it is equipped with annular butt block 42 to be equipped with annular butt block in the inner wall epirelief of this barrel 41, butt block 42 tip is equipped with the arc wall 421 corresponding with spacing wall 11, this arc wall 421 is the interval with spacing wall 11 and sets up, the both ends of barrel 41 and the sealed butt of the open end inner wall of open slot 31, form sealed chamber 5 between barrel 41 inner wall and the open slot 31 inner wall, it is filled with fluid 6 in this sealed chamber.

The ports at the two ends of the outer pipe 2 are respectively bent inwards to form a surrounding edge 21, the rubber body 3 is wholly surrounded and fixed in the outer pipe 2 through the surrounding edge 21, the deviation of the rubber body 3 is effectively prevented, and the structural reliability is further improved.

There are also two annular resilient recesses 411 on the outer wall of the barrel 41. When the cylinder body 41 is subjected to severe vibration, the elastic groove 411 can be used for extrusion buffering, and the risk of breakage of the cylinder body 41 is reduced.

The utility model discloses a when this kind of structure, vehicle met great vibrations, more effective shock attenuation buffering was carried out to fluid 6 in the accessible seal chamber 5, and the buffer of contacting can be carried out with the outer wall of inner tube 1 to the butt joint piece 42 on the holder 4 simultaneously, further improves the reliability of structure, prevents the excessive extrusion wearing and tearing of rubber body 3, improves life, has just so realized the technical effect that the structure is reliable and the shock attenuation effect is better.
