Abstract
The utility model discloses a maintenance-free cross shaft which comprises a cross shaft body which is hollow. A cavity which is used for storing oil is arranged in the cross shaft. The cross shaft body includes four shaft ends, an oil-control valve is arranged at the position of the shaft end of the cross shaft body next to a cross center. A locking-type framework multi-lip sealing ring made of new materials is arranged between the oil-control valve and a bearing outer ring assembly. The hollow cavity of the cross shaft is used for storing a certain amount of oil. According to a first- lost first-served principle of the control valve, supplying oil to four bearing outer ring assemblies of the cross shaft is slowly carried out. An automobile does not need to carry out a regular cross shaft maintenance work; many procedures of the automobile maintenance are reduced. The oil-control valve controls the stored oil to slowly discharge the oil to the four shaft ends of the cross shaft, and real-time lubricant effects are reached. A premature wearing phenomenon of the cross shaft caused by lacking maintenance and lubricating grease is prevented and the reasonable operation of the automobile is guaranteed.
Description
Technical field
The utility model relates to a kind of automobile chassis drive system part, especially a kind of cross axle that avoids safeguarding.
Background technique
Now the quantity of private savings automobile is more and more, and the automobile that often uses needs regular care and maintenance, but realize not strong situation happen occasionally because of various reasons by in time maintenance or maintenance for a lot of car owners.In the situation that can not get for a long time maintenance, can have a greatly reduced quality as the lubrication effect of the cross axle of automobile important spare part, cause the premature wear of cross axle, with the shake that power train occurs, noise, the even fracture of transmission shaft, curved surrender.Traditional maintenance method, is delivered to 4 S auto shop with car transmission shaft is carried out the routine maintenance under the condition that maintenance consciousness is arranged for the car owner, and when wherein requiring assembling, oil cup opening must be towards the same direction of transmission shaft.Such maintenance method is not only wasted time and energy, and in the situation that forget and probably cause the cross axle lack of lubrication, cause cross axle wearing and tearing, alter axle.
Because cross axle lubricates the problem that the maintenance deficiency causes, the claimant utilizes the control fuel tap to design a kind of cross axle from the type that overflows in order to reduce automobile.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the claimant gropes through long-term practice aborning, has designed a kind of non-maintaining cross axle.
Technological scheme: in order to realize the foregoing invention purpose, the technological scheme that the utility model adopts is: a kind of non-maintaining cross axle, comprise the cross axle axis body, and cross axle hollow forms a cavity that is used for oil storage.Described cross axle axis body has four axle heads, the axle head of described cross axle axis body is provided with a control fuel tap near the position at cross center, the remote location of described cross axle axis body is provided with a locking device, is provided with lip seal circle more than between described control fuel tap and locking device.Described many lip seals circle adopts polytetrafluoroethylmaterial material Baogang frame to manufacture, and the place forms the many lips in both sides at interior ring, with interference fit, makes bearing outer ring assembly and the cross axle formation seal space that closely cooperates due to many lips and spindle nose shoulder under the locking device active force.Like this after assembling is complete, to fill it up with lubricant grease in the cross axle center cavity, by the effect of locking device, stoped the intrusion of extraneous water, mud etc. also to prevent the leakage of internal lubrication grease, use the effect of control fuel tap for a long time lentamente to four bearing outer ring assembly fuel feeding of cross axle.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: 1, utilize the hollow cavity of cross axle to store a certain amount of lubricating grease, this storage volume is 2.7 times of like product, avoid automobile regularly to carry out the work of cross axle maintenance, reduced many links of automobile maintenance; 2, control oil storage by the control fuel tap and slowly discharge lubricant grease to four bearing outer ring assemblies of cross axle, reached real-time lubricated effect, ensured cross axle normal operation running; 3, to a certain extent, reduced the maintenance cost that adopts traditionally oiling agent lubricated.4, adopt many lip seals circle of new material teflon to have high-low temperature resistant, contact frictional resistance is little, wearing and tearing are little, media-resistant, intensity is good and the performance such as long service life.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of non-maintaining cross axle of the utility model.
Embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, the technical program is elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of non-maintaining cross axle of the utility model comprises cross axle axis body, many lip seals circle 2, and described cross axle axis body has four axle heads, and the cavity of a hollow of cross axle central authorities' existence is filled with lubricant grease in described cross axle center cavity.
The axle head of described cross axle axis body is provided with a control fuel tap 3 near the position at cross center, and the remote location of described cross axle axis body is provided with a locking device 1, is provided with lip seal circle 2 more than between described control fuel tap 3 and locking device 1.
Described many lip seals circle 2 adopts new material teflon Baogang frame to manufacture, the place forms the many lips in both sides at interior ring, with interference fit, make bearing outer ring assembly and the cross axle formation seal space that closely cooperates due to many lips and spindle nose shoulder under locking device 1 active force.
Claims (2)
1. non-maintaining cross axle, comprise the cross axle axis body, described cross axle axis body has four axle heads, it is characterized in that: the axle head of described cross axle axis body is provided with a control fuel tap (3) near the position at cross center, the remote location of described cross axle axis body is provided with a locking device (1), is provided with lip seal circle more than (2) between described control fuel tap (3) and locking device (1).
2. a kind of non-maintaining cross axle according to claim 1, it is characterized in that: described many lip seals circle (2) adopts polytetrafluoroethylmaterial material Baogang frame to manufacture and forms, the place forms the many lips in both sides at interior ring,, make between bearing outer ring assembly and cross axle under locking device (1) active force and form seal space with interference fit due to many lips and spindle nose shoulder.
