Abstract
The utility model relates to a car wheel nut which comprises a nut main body and a positioning shaft. The car wheel nut further comprises a cone part. The nut main body is a polygon hollow cylinder. An inner screw thread is arranged on the inner edge of an inner edge attack. The positioning shaft is a hollow cylinder. The nut main body is connected with one end of the positioning shaft and the cone part is connected with the other end of the positioning shaft. Besides, a triangle groove is opened in a straight line of the outer edge of the nut main body. According to the car wheel nut, the car wheel is fit on a wheel hub firmly and the car wheel does not interfere with a bolt screw thread. Disassembling is easy and service life is prolonged.
Description
Technical field
The utility model relates to the fastening piece that a kind of automobile is used, particularly a kind of nut of automotive wheel locking usefulness.
Background technique
Along with the development of science and technology, the progress of technology, automobile product makes rapid progress, and for people's everyday life must almost become indispensable articles for use, automobile each component part when design all is pre-set according to designing requirement, with link and fastening piece assembling.These component parts, link and fastening piece are used for guaranteeing Security and the travelling comfort of Vehicle Driving Cycle jointly.But because Vehicle Driving Cycle is after a period of time, these parts of reason, link and the fastening pieces such as, tire wear impaired owing to severe jolt, chassis part that parts depreciation, road uneven cause produce mass change.In case producing mass change just may produce such as safety problems such as abnormal tyre wearing and tearing, parts depreciation quickening, in the process of moving unstable, oil consumption of vehicle increase.In maintenance during dismounting, need to fastening piece for example bolt pull down, being dismounted for multiple times can cause for example thread failure of bolt of fastening piece, easily causes resonance and fatigue ruption, affects the working life of product.Along with the expansion of domestic automobile consumption market and the people day by day diversification with the car theory, must there be renewal, Fastener products more fully in the market that tackle better continuous variation, for the Consumer creates finer, vehicle safety more easily.The Placement that the wheel fastening system adopts is pressing-riveting bolt and lug nut secure fit, the connection defective is arranged because the structural type problem of lug nut is even, aligning in assembly process for example, the sphere beating degree control difficulty of sphere wheel nut, certainly will affect assembly quality, because also can existing certain Assembly Interference to form, the long foozle problem that screws screw thread kills phenomenon in addition, exposed also can the causing because of the factor of service condition of wheel bolt got rusty, can't normally dismantle after being threaded after the corrosion, these affect the safety of wheel running gear.
The model utility content
The purpose of this utility model provides a kind of safer wheel nut simple in structure, easy to use, to solve the problem of prior art.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of wheel nut, comprise a nut main body and a positioning shaft, also comprise a cone part, described nut main body is a polygonal hollow cylinder, and inner edge has been attacked internal thread, and described positioning shaft is a hollow circular cylinder, described nut main body be connected an end of positioning shaft and connect, described cone part be connected the other end of positioning shaft and connect, in addition, have the triangle groove on the outer rim straight line of described nut main body.
According to the described wheel nut of the utility model preferred embodiment, the cone angle angle of described cone part is 60 degree.
According to the described wheel nut of the utility model preferred embodiment, the inner edge of described cone part does not have screw thread.
Since adopted above technological scheme, so that the utlity model has following advantageous effect:
The first, the mode of the utility model employing cone part cone angle angle 60 degree cooperation compressions can be with the wheel secure fit on wheel hub; The design of positioning shaft can be installed a plurality of wheel nuts simultaneously simultaneously, has eliminated the problem of the assembling discontinuity that causes because of personal factor;
The second, counterbore and screw-thread fit allow bolt head no longer interfere with internal thread, and it is easier to dismantle;
Three, the triangle groove directly is buckled in the plastics block end of nut, and the materials such as the water when avoiding Vehicle Driving Cycle and dust are invaded, and have improved working life.
Description of drawings
Fig. 1 is the structural representation of the utility model wheel nut;
Fig. 2 is the cut-away diagram of the utility model wheel nut.
Embodiment
Below in conjunction with accompanying drawing, specify the utility model;
Please refer to Fig. 1 and Fig. 2, shown in the structural representation of the utility model wheel nut, wheel nut comprises a nut main body 10 and a positioning shaft 20, also comprise a cone part 30, described nut main body 10 is a polygonal hollow cylinder, nut main body described in the present embodiment 10 is the Hexagon hollow cylinder, inner edge has been attacked internal thread, described positioning shaft 20 is a hollow circular cylinder, described nut main body 10 be connected an end of positioning shaft 20 and connect, described cone part 30 be connected the other end of positioning shaft 20 and connect, in addition, have triangle groove 11 on the outer rim straight line of described nut main body 10; The cone angle angle of described cone part 30 is that the inner edge of 60 degree and cone part 30 does not have screw thread.
Wheel nut of the present utility model, the mode that adopts the design of cone angle angles 60 degree to cooperate to compress in cone part 30 with the wheel secure fit on wheel hub; And cooperating cone part 30 cone angle faces and nut main body 10 places to increase the positioning shaft 20 of a straight cylinder section, location when being used as the wheel nut installation is used, can simultaneously 4-6 wheel nut be installed simultaneously, and can accomplish accurate location, eliminated the problem of the assembling discontinuity that causes because of personal factor.
In addition, change the Full Thread FT form into counterbore and thread fiting mode, under the prerequisite that guarantees fastening force, can allow bolt head no longer cause interference with internal thread, done degree of dodging, can satisfy smoothly usage requirement like this.
In addition; outer rim straight line at wheel nut is offered triangle groove 11; be convenient to the plastics block directly is buckled in the end of wheel nut, the wheel nut after effectively double thread connects carries out seal protection, and the materials such as the water when avoiding Vehicle Driving Cycle and dust are invaded.
Since adopted above technological scheme, so that the utlity model has following advantageous effect:
The first, the mode of the utility model employing cone part cone angle angle 60 degree cooperation compressions can be with the wheel secure fit on wheel hub; The design of positioning shaft can be installed a plurality of wheel nuts simultaneously simultaneously, has eliminated the problem of the assembling discontinuity that causes because of personal factor;
The second, counterbore and screw-thread fit allow bolt head no longer interfere with internal thread, and it is easier to dismantle;
Three, the triangle groove directly is buckled in the plastics block end of nut, and the materials such as the water when avoiding Vehicle Driving Cycle and dust are invaded, and have improved working life.
Above disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should drop in the protection domain of the present utility model.
