With.
Currently, common hub nut is usually used simple nut head and is formed in conjunction with the riveting of gasket in the market.
Due to its simple design structure, the problem for causing to occur more in use.Such as：1, wheel hub spiral shell in the prior art
Female and removable insole pieces generally use carbon steel 45, its service performance is poor after conditioned processing；2, the effective length of threaded hole
It is shorter, it is traditionally arranged to be between 22mm-25mm, such screw thread effectively causes its forced area also to greatly reduce using length,
In use, wearability, anti-shear performance, tensile property, resistance to shock etc. can all decline therewith；3, nut and it is living
Generally riveted using circular arc between mobile gasket or not riveted structure, such connection type in use, especially on road
In the case that condition is severe, since wheel bolt vibration frequency is very big, nut is caused easily to fail.When serious, vehicle may result in
Ruin the consequence that people dies；4, threaded hole is generally arranged by the way of straight-through, so that the tail end of boss bolt is all an exposure to
It is outdoor, after exposing to the sun and rain, many sand and dust can be seriously destroyed and overstock at the threads of boss bolt, when dismantling again
When wheel tyre, the screw thread of boss bolt will be seriously destroyed and ultimate failure, to reduce service life.
Utility model content
The utility model to solve the above-mentioned problems, provides a kind of reasonable in design, practical, connective stability
It is good, there is dust-proof effect, the heavy truck hub nut of boss bolt service life can be greatly improved.
The utility model adopts the following technical solution：
A kind of heavy truck hub nut, including nut body, the nut body include nut head, dust-proof blanking cover and work
Mobile gasket, the nut head inside are equipped with the internal thread hole screwed in for bolt, set at the end position of one end of the nut head
There is annular slot, the dust-proof blanking cover is connected in annular slot, far from one end lateral wall of annular slot in the nut head
It is equipped with the convex edge being arranged along the circumferential direction of nut head, one end inner sidewall of the removable insole pieces is equipped with and positions
The locating slot that convex edge matches is realized by convex along the mode being connected in locating slot between the nut head and removable insole pieces
Connection.
As a kind of optimal technical scheme of the utility model, the end section on the locating slot close to annular slot is
The arcuate structure expanded outwardly, another end section of the locating slot are structure of right angle tyoe, and the convex is along upper close to positioning
The side of the expansion end of slot is equipped with the first inclined-plane, and the convex is equipped with second tiltedly along the side of upper remotely located slot expansion end
Face.
As a kind of optimal technical scheme of the utility model, on the inner sidewall of the removable insole pieces and close to locating slot
It is additionally provided with third inclined-plane at position, corresponds at the position on third inclined-plane on the lateral wall of the nut head and is equipped with and third inclined-plane
The 4th inclined-plane to fit.
As a kind of optimal technical scheme of the utility model, the nut head and removable insole pieces are all made of carbon steel alloy
40Cr is made after normalizing and modifier treatment.
As a kind of optimal technical scheme of the utility model, the length of the threaded hole is 42mm-45mm.
As a kind of optimal technical scheme of the utility model, the outer diameter of the removable insole pieces is 47mm-48mm.
The utility model has the beneficial effects that：
1, the dust-proof blanking cover of the utility model setting all can wrap the threads of boss bolt in spiral shell when in use
In female, it will not meet with and expose to the sun and rain, when removing vehicle tyres tire, the threads of boss bolt are not subject to destroy, turn
Freely, to effectively increase the service life of boss bolt, use cost has been saved；
2, real along the mode being connected in locating slot by convex between the nut head and removable insole pieces of the utility model
It now connects, the connective stability between nut head and removable insole pieces can be greatly improved, avoid the situation severe in road conditions
Under, since wheel bolt vibration frequency is very big, cause nut this subject fail the case where, thus improve nut body use peace
Quan Xing；
3, the length of threaded hole is set 42mm-45mm by the utility model, so that screw thread forced area greatly increases, this
When wheel bolt can tightly be blocked, thus to substantially increase the anti-loosening property, resistance to shock, pull resistance of nut body
Energy, wearability, anti-shear performance, while increasing the service life of boss bolt；
4, the outer diameter of removable insole pieces is set 47mm-48mm by the utility model, considerably increases its contact with wheel hub
Area is more evenly distributed in nut lock clamp force, wheel hub shearing force on all screw threads, and then effectively increases its tension
Performance, when use, are stronger, and tensile property is more preferable.
