Abstract
The utility model embodiment discloses a kind of trailer VB suspension mandrels, the utility model devises circular trough in the lubricating grease channel exit increase of mandrel, the design of this circular trough plays a part of shunting lubricating grease, so that mandrel is during oiling, lubricating grease is by can rapidly be diverted to mandrel circular trough surrounding behind outlet, accordingly even when in the case of brass bushing and mandrel mating surface gap very little, lubricating grease also can quickly and evenly pass through the oil guide groove of brass bushing, realize that lubricating grease is quickly and evenly distributed in brass bushing surrounding, reach the purpose of grease lubrication protection mandrel and brass bushing；This is designed to ensure that mandrel is smooth in oiling rotation at initial stage, effectively improves the service life of brass bushing and mandrel.
Description
Technical field
It the utility model is related to trailer suspension field, more particularly to a kind of trailer VB suspension mandrels.
Background technology
In trailer VB suspension, connected by mandrel between equalizer bar and support, rotated to reach protection equalizer bar
Operating mode under mandrel be not destroyed, need to equalizer bar spiro keyhole position install additional brass bushing；, need to be to ensure that it is smooth that equalizer bar rotates
Lubricating grease is injected between brass bushing and bolt mating surface.
At present, due between brass bushing and mandrel mating surface gap it is smaller, the lubricating grease injected by mandrel oil filler point
Brass bushing surrounding can not be quickly and evenly distributed in, causes brass bushing and mandrel earlier period damage, the phenomenon of short life.
Therefore it provides a kind of trailer VB suspensions that can improve brass bushing and mandrel service life are this area with mandrel
Technical staff's technical issues that need to address.
Utility model content
The utility model embodiment discloses a kind of trailer VB suspension mandrels, can ensure that mandrel rotates initial stage in oiling
It is smooth, effectively improve the service life of brass bushing and mandrel.
The utility model embodiment provides a kind of trailer VB suspension mandrels, including：Bushing and mandrel；
The bushing and mandrel socket；
The mandrel surface sets fluted, and the groove is used for being carried out to lubricating grease during the mandrel oiling
Shunting so that lubricating grease can be uniformly distributed in the sleeve surface.
Preferably, the groove is circular groove.
Preferably, a kind of trailer VB suspension mandrels provided in an embodiment of the present invention also include：Support and equalizer bar；
The support is connected by the mandrel with the equalizer bar.
Preferably, the bushing is brass bushing.
As can be seen from the above technical solutions, the utility model embodiment has advantages below：
The utility model embodiment provides a kind of trailer VB suspension mandrels, including：Bushing and mandrel；The bushing and
The mandrel socket；The mandrel surface set it is fluted, the groove be used for during the mandrel oiling to lubrication
Fat is shunted so that lubricating grease can be uniformly distributed in the sleeve surface.The utility model designs in conventional fuel mandrel
Under increased a circular trough newly, for shunting lubricating grease.Oiling mandrel compared to tradition without circular splitter box, this practicality are new
In the case of brass bushing and mandrel mating surface gap very little, lubricating grease quickly and evenly can also enter in bushing type,
So as to reach the purpose of lubricating grease fast lubricant protection mandrel and brass bushing, the use longevity of brass bushing and mandrel is improved
Life.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of the trailer VB suspension mandrels provided in the utility model embodiment；
Fig. 2 is a kind of another structural representation of the trailer VB suspension mandrels provided in the utility model embodiment；
Wherein, marked in figure as described below：
1. the lubricating grease flow range of 5. groove of mandrel 2. bushing, 3. equalizer bar, 4. support 6.
Embodiment
The utility model embodiment discloses a kind of trailer VB suspension mandrels, can ensure that mandrel rotates initial stage in oiling
It is smooth, effectively improve the service life of brass bushing and mandrel.
It refer to Fig. 1 and Fig. 2, an a kind of implementation of trailer VB suspension mandrels that the utility model embodiment provides
Example, including：Bushing 2 and mandrel 1；
Bushing 2 and mandrel 1 are socketed；
The surface of mandrel 1 sets fluted 5, and groove 5 is used for being shunted to lubricating grease during mandrel oiling so that
Lubricating grease can be uniformly distributed in the surface of bushing 2, as shown in lubricating grease flow range 6 in Fig. 2.
Further, groove 5 is circular groove, and the design of circular trough plays a part of shunting lubricating grease so that mandrel 1 exists
During oiling, lubricating grease is by can rapidly be diverted to the circular trough surrounding of mandrel 1 behind outlet.Moreover, even in bushing 2 with
In the case of the mating surface gap very little of mandrel 1, lubricating grease also can realize injection quickly and evenly by the oil guide groove of bushing 2
Lubricating grease is quickly and evenly distributed in the surrounding of bushing 2, can reach the mesh of lubricating grease fast lubricant protection mandrel 1 and bushing 2
, ensure that mandrel 1 rotates smooth, the service life of raising bushing 2 and mandrel 1 initial stage in oiling.
Further, a kind of trailer VB suspension mandrels provided in an embodiment of the present invention also include：Support 4 and equalizer bar 3；
Support 4 is connected by mandrel 1 with equalizer bar 3.
Further, bushing 2 is brass bushing.
A kind of lubricating grease channel exit increase design for trailer VB suspension mandrels that the utility model embodiment provides
Circular trough, the design of this circular trough play a part of shunting lubricating grease so that mandrel is during oiling, and lubricating grease is by going out
Mandrel circular trough surrounding can be rapidly diverted to after mouthful, accordingly even when in brass bushing and the feelings of mandrel mating surface gap very little
Under condition, lubricating grease also can realize that lubricating grease is quickly and evenly distributed in Huang quickly and evenly by the oil guide groove of brass bushing
Copper bush surrounding, reach the purpose of grease lubrication protection mandrel and brass bushing；This is designed to ensure mandrel in oiling
Initial stage, rotation was smooth, effectively improved the service life of brass bushing and mandrel.
A kind of trailer VB suspensions provided by the utility model are described in detail with mandrel above, for this area
Those skilled in the art, according to the utility model embodiment thought, have change in specific embodiments and applications
Become part, in summary, this specification content should not be construed as to limitation of the present utility model.
