Abstract
The utility model discloses a kind of axis head nuts, including nut body, there are one threaded holes for setting on the nut body, the fastener hole runs through nut body, cotter way there are six being set on the end face of described nut body one end, the cotter way is uniformly distributed along the axis direction of nut body, protrusion is formed between cotter way, there are three the reversed equally distributed fastener holes of axis by nut body for setting on protrusion side wall on the protrusion, and there are one deformation gaps in the setting of the center of each cotter way.The axis head nut of having determined of the utility model is limited by cotter way, and easy the problem of loosening.
Description
Technical field
The utility model is related to auto parts and components manufacture fields, and in particular to a kind of automobile axis head nut.
Background technology
Automobile shaft currently on the market, axle include spindle nose and central siphon, and hub bearing, wheel hub are equipped between spindle nose and wheel hub
Bearing is a pair of of taper roll bearing, respectively inner bearing and outer bearing, the outer ring lateral surface of bearing and the surface of internal cavity of wheel hub
Location and installation, inner ring medial surface and the spindle nose excircle orientation of bearing are installed, and axis head nut adjusts bearing clearance.In order to maintain
It is convenient, it is provided with opening cotter way on axis head nut, split pin is inside inserted with, when needing to dismantle spindle nose component, split pin is taken out,
Nut can be removed, bearing is taken out.However present spindle nose spiral shell nut makes axis head nut twist for the cotter way on cooperation central siphon
It is too tight or too loose, it easily causes using upper defect and repair trouble, if being not inserted into split pin easily causes nut loosening again.
Utility model content
The purpose of this utility model is to provide a kind of automobile axis head nuts, make which solve axis head nuts by cotter way
Limitation, and easy the problem of loosening, to be more suitable for using.
To achieve the above object, the utility model provides following technical solution：It is a kind of to use axis head nut, including nut
Body, there are one threaded holes for setting on the nut body, and fastener hole is respectively provided on each clamping face of the nut body, described
Fastener hole runs through nut body, is set on the end face of described nut body one end there are six cotter way, the cotter way along nut body axis
Line direction is uniformly distributed, and protrusion is formed between cotter way, and there are one tight for setting on the protrusion side wall on the protrusion
Solid hole, the fastener hole are threaded hole；The fastener hole is vertical and passes through cotter way, and extends to an adjacent protrusion
And run through protrusion, and there are one fastening bolts for setting on the fastener hole.
By using above-mentioned technical proposal：Fastener hole is provided on the protrusion side wall, the fastener hole hangs down
It is straight and run through cotter way, and extend on an adjacent protrusion, and fastening bolt is provided on the fastener hole, it can be with
It plays and anti-loosening processing is carried out to axis head nut in the case of no split pin.
The further setting of the utility model：The number of the fastener hole can be three, and fastener hole presses nut body
Axis be reversely uniformly distributed, so that the protrusion is only had on the protrusion side wall of side and be provided with fastener hole.
By using above-mentioned technical proposal：The fastener hole number is set as three, and the axis for pressing nut is reversely equal
Even distribution, even if can be tightened at least one fastener hole therein if in the case of being inserted into split pin in cotter way.
The further setting of the utility model：Protrusion sidewall end, which is extended to, in the fastener hole is provided with head of avaling
Point.
By using above-mentioned technical proposal：Protrusion sidewall end setting countersunk head portion is extended in the fastener hole, can be kept away
Exempt from the head protrusion interference of fastening bolt.
The further setting of the utility model：In the center of each cotter way, there are one deformation gaps for setting.
By using above-mentioned technical proposal：In the center of each cotter way, there are one deformation gap, energy for setting
Axis head nut is set to carry out deformation in a certain range, to make axis head nut have preferably anti-loosening effect.

Specific implementation mode
One embodiment of the utility model is described further referring to figs. 1 to Fig. 4.
A kind of to use axis head nut, including nut body 1, there are one threaded hole, the fastener holes for setting on the nut body
Through nut body 1, set on the end face of described 1 one end of nut body there are six cotter way 2, the cotter way 2 along nut body 1 axis
Line direction is uniformly distributed, and forms protrusion 7 between cotter way 2, one is provided on the protrusion side wall 6 on the protrusion 7
A fastener hole 8, the fastener hole 8 are threaded hole；The fastener hole 8 is vertical and passes through cotter way 2, and extends to adjacent one
A protrusion and run through protrusion 7；And there are one fastening bolts 4 for setting on the fastener hole 8.In the protrusion side
Fastener hole 8 is provided on wall 6, the fastener hole 8 is vertical and runs through cotter way 2, and extends on an adjacent protrusion 7,
And fastening bolt 4 is provided on the fastener hole, when tightening fastening bolt 4 the protrusion 7 of two connections can draw close,
Anti-loosening processing is carried out to axis head nut in the case of no split pin so as to play.
The number of the fastener hole 8 can be three, and fastener hole 8 is reversely uniformly distributed by the axis of nut body 4, is made
It is provided with fastener hole 8 on the protrusion 7 only protrusion side wall 6 of side；Described 8 numbers of fastener hole are set as three
It is a, and be reversely uniformly distributed by the axis of nut, though if in the case of being inserted into split pin in cotter way 2 can to it is therein extremely
A few fastener hole is tightened, and ensures to be not in the case where two fastener holes 8 run through mutually.In the fastener hole 8
It extends to 6 end of protrusion side wall and is provided with countersunk head portion 5；6 end of protrusion side wall setting countersunk head portion is extended in the fastener hole 8
5, it is avoided that the head protrusion interference of fastening bolt 4.In the center of each cotter way 2, there are one deformation gaps for setting
3；The range of the width in the deformation gap should be controlled in 1mm~2.3mm.Pass through the centre bit in each cotter way 2
Deformation gap 3 there are one installing, can make the protrusion 7 of axis head nut carry out deformation in a certain range, and can improve whole
Intensity；To make axis head nut have preferably anti-loosening effect.The foregoing is merely the preferable implementations of the utility model
Example, is not intended to limit the utility model, those skilled in the art carries out usually within the scope of technical solutions of the utility model
Variations and alternatives all should include within the protection scope of the present utility model.
