To achieve the above object, the utility model provides the following technical solutions:
A kind of vehicle bridge axis head nut locking device, including spindle nose and the locking nut being set on spindle nose, the spindle nose
End offers keyway, further includes:
Stop washer, inner ring are equipped with and the matched stop tooth of keyway；
Lock washer, inner ring be equipped with the matched locking teeth of keyway, offer several half slots on outer ring；
And clamping screw, end are embedded in the threaded hole of locking nut, the threaded hole matches with half slot, and spiral shell
Pit is threadedly engaged with clamping screw；
The one side of the locking nut be equipped with annular and be used for mounting lock washer concave station, the stop washer,
Locking nut and lock washer are sequentially sleeved at spindle nose periphery.
Further, the center of the threaded hole is located on the outer ring of concave station.
Further, the threaded hole is equipped with several, and several threaded holes are distributed on the outer ring of concave station.
Further, the threaded hole is equipped with 2, and the half slot is equipped with 18.
Further, the stop tooth and locking teeth are respectively positioned on inside keyway.
Further, the outer ring of the locking nut offers convenient for hand-held arc groove.
The utility model also provides a kind of vehicle, includes above-mentioned vehicle bridge axis head nut locking device.
The beneficial effects of the utility model are:
1, by threaded hole and half slot, the precise fine-adjustment positioning of locking nut is realized, adjusts bearing to reach accurate
Gap, the purpose for increasing bearing life, it is convenient to assemble, and disassembly process does not generate vulnerable part, structure novel.
2, compared to the prior art, clamping screw is directly embedded into the threaded hole of locking nut, is with positioning and locking nut
Can, it avoids having no need to change spindle nose original structure in spindle nose pin hole, avoids influencing spindle nose intensity, meanwhile, occupy the axis of spindle nose
It is short to length, it is conducive to reduce vehicle bridge entire length, saves transportation cost.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
In attached drawing: 1- spindle nose, 101- keyway, 2- locking nut, 201- threaded hole, 202- concave station, 203- arc groove, 3- stop

Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below with reference to the utility model
Attached drawing carries out clear, complete description to the technical solution of the utility model, and based on the embodiment in the application, this field is general
Logical technical staff other similar embodiments obtained without making creative work, all should belong to the application
The range of protection.In addition, the direction word mentioned in following embodiment, such as "upper" "lower" " left side " " right side " etc. are only with reference to attached drawing
Direction, therefore, the direction word used is for illustrative and not limiting the invention.
The utility model is described in further detail with preferred embodiment with reference to the accompanying drawing.
Embodiment one:
Refering to what is shown in Fig. 1, a kind of vehicle bridge axis head nut locking device, including spindle nose 1, locking nut 2, stop washer 3,
Lock washer 4 and clamping screw 5, wherein the stop washer 3, locking nut 2 and lock washer 4 are sequentially sleeved at outside spindle nose 1
It encloses.Specifically, 1 end of spindle nose offers keyway 101, the inner ring of stop washer 3 is equipped with and the matched stop of keyway 101
Tooth 301, the inner ring of lock washer 4 be equipped with the matched locking teeth 401 of keyway 101, offer several half slots on outer ring
