The specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.

Refer to Fig. 1, a kind of automotive hub, comprising: a wheel rim 1, a spoke 2, three rolling bodys 4.Wherein, the fixing installing of this wheel rim 1, not rotatable, this spoke 2 can be interior along an assigned direction rotation (being unidirectional rotation) coaxial with wheel rim 1 at wheel rim 1, and three rolling body 4 equal angles are distributed between spoke 2 and wheel rim 1.

Automotive hub also comprises: three springs 3, three centrifugal-blocks 5 and three set pins 6.

In practical application, the quantity of rolling body 4 be not limited to three, can any amount a plurality of; Correspondingly, the quantity of spring 3, centrifugal-block 5 and set pin 6 is also not limited to three, and can be any number identical with rolling body 4 quantity.

Fig. 2 is the part sectional view of the spoke of the automotive hub shown in Fig. 1.Please in referring to Fig. 1 again in conjunction with Fig. 2:

Spoke 2 is distributed with the spoke 2b with identical with rolling body 4 quantity (the present embodiment only be take three as example) near the outward flange equal angles of wheel rim 1, is placed with a rolling body 4 in each spoke 2b;

One side of a rolling body 4 of placing in each spoke 2b have sidewall with a spoke inner chamber body 2a, this sidewall with spoke inner chamber body 2a in be placed with a spring 3, and, one end of this spring 3 is stretched in spoke inner chamber body 2a, the other end stretches out outside spoke inner chamber body 2a, thereby this spring 3 is when normality, can push this rolling body 4 contact wheel rims 1;

The opposite side of a rolling body 4 of placing in each spoke 2b is equiped with a centrifugal-block 5, and, this centrifugal-block 5 is installed in spoke 2, also can be swung around set pin 6 by a set pin 6, thereby this centrifugal-block 5 is rocked to behind an angular deflection position rotating with spoke 2 centnifugal force producing, can promotes this rolling body 4 and overcome the extruding of spring 3 and connect and depart from wheel rim 1.
