The automotive hub of slanted bar formula spoke
Technical field
The utility model relates to a kind of automotive hub of slanted bar formula spoke, belongs to the automotive wheel product technical field.
Background technology
The wheel hub of present more employed automotive wheels, the wheel nave of car particularly, spoke on its wheel hub is to adopt radially to be provided with, be that the trend of spoke spoke line of centers and the radius of wheel hub or the line of centers of diameter are to coincide, the wheel nave of this structure in vehicle ' when wheel is subjected to the impulsive force of ground obstacle, because impulsive force is not radially sometimes, thus when impact the stressed accentric often of wheel hub, the wheel hub that spoke so radially is set very easily is damaged.
Summary of the invention
The utility model provides a kind of automotive hub of slanted bar formula spoke of novelty, adopts non-radial spokes that structure is set, and with the impact resistance of raising wheel hub and the purpose in service life, realizes vehicle safe driving.
The technical solution adopted in the utility model is:
A kind of automotive hub of slanted bar formula spoke, comprise: wheel rim, spoke, wheel hub structure, wheel rim is connected with spoke, spoke is connected with the wheel propeller boss, the incline structure setting radially of the spoke of spoke, the line of centers of the line of centers of inclination spoke and hub radius or diameter forms an angle, and the angle of the angle that forms is five to 20 degree.
The spoke of spoke is the curved structure of arc bend along radiation direction.
The utility model beneficial effect is:
Owing to adopted the automotive hub of slanted bar formula spoke of the present utility model, the impact resistance and the service life of wheel hub greatly improve, make that the wheel hub of wheel is not fragile when being subjected to impacting, the realization vehicle safe driving uses, have very strong creativeness and practicality, thereby market outlook are boundless.

The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3.
A kind of automotive hub of slanted bar formula spoke, comprise: wheel rim 1, spoke 2, wheel propeller boss 3 structures, wheel rim 1 is connected with spoke 2, spoke 2 is connected with wheel propeller boss 3, the incline structure setting radially of the spoke of spoke 2, the line of centers of the line of centers of inclination spoke and hub radius or diameter forms an angle, and the angle of the angle that forms is five to 20 degree.
The spoke of spoke 2 is the curved structure of arc bend along radiation direction.
By the mold integral press forming, the wheel hub of press forming is realized the accurate dimension typing through machine up with whole wheel hub, and machinery processes each connecting bore, the installation that matches with rubber tyre then, and after installing plunger, promptly inflatable the use.
