The automotive hub of strain formula spoke
Technical field
The utility model relates to a kind of automotive hub of strain 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 expanded letter formula three spokes or four spoke structures, in actual use, the wheel spoke of the few spoke structure of this expanded letter formula will cause whole wheel hub to scrap as long as a spoke damages when colliding article, exist the phenomenon of unbalance stress simultaneously, influence the safety that vehicle uses like this.
Summary of the invention
The utility model provides a kind of automotive hub of strain formula spoke of novelty, adopts dendroid Y shape structure spoke, and with the stress performance of raising wheel hub, thereby realization increases the service life and the purpose of vehicle safe driving.
The technical solution adopted in the utility model is:
A kind of automotive hub of strain formula spoke, comprise: wheel rim, spoke, wheel hub structure, wheel rim is connected with spoke, and spoke is connected with the wheel propeller boss, spoke constitutes built-in reinforcing rib structure in the dendroid Y shape structure spoke by ten to 20 dendroid Y shape structure spokes.
The dendroid Y shape structure spoke of spoke is uniformly distributed on the circumference, and the angle of angle is 30 degree between the Y shape branch of dendroid Y shape structure.
The utility model beneficial effect is:
Owing to adopted the automotive hub of strain formula spoke of the present utility model, the stress performance and the service life of wheel hub greatly improve, make that the spoke of wheel is not fragile when colliding article, 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 strain formula spoke, comprise: wheel rim 1, spoke 2, wheel propeller boss 3 structures, wheel rim 1 is connected with spoke 2, and spoke 2 is connected with wheel propeller boss 3, spoke 2 constitutes built-in reinforcing rib structure in the dendroid Y shape structure spoke by ten to 20 dendroid Y shape structure spokes.
The dendroid Y shape structure spoke of spoke 2 is uniformly distributed on the circumference, and the angle of angle is 30 degree between the Y shape branch of dendroid Y shape structure.
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.
Because spoke 2 adopts dendroid Y shape structure spoke, when some damage of several spokes is arranged on the wheel hub of wheel in vehicle uses, temporarily can't influence the normal use of vehicle, make vehicle use safety and convenient more like this.
