r≥d1≤d2.

The utility model also provides a kind of structural strength good oil filling pipe.

For achieving the above object, the technical scheme of the utility model oil filling pipe is:

Using the oil filling pipe of described flat bellows, described oil filling pipe includes the hard tube for connecting oil filler and is used for The flat bellows of arrangement pipeline trend.

The utility model compared with prior art, has the advantage that

Flat wall is the equal of that reinforcement makes bellows axially obtain support, on the one hand improves the axial direction of bellows Structural strength, reduces the deflection that bellows inside and outside differential pressure leads to, and is on the other hand easy to arrange the trend of bellows, the two is simultaneous ?.Using the oil filling pipe of bellows, improve the intensity of oil filling pipe on the whole, reduce the deflection that inside and outside differential pressure leads to, full Sufficient vehicle performance requires.
