Abstract
The utility model discloses a bellows. This bellows includes pipe wall and bellied ripple, the ripple for setting up the semi -ring ripple in the pipe wall both sides, semi -ring corrugated both ends tangent or crossingly constituted level and smooth wall with the pipe wall, level and smooth wall spiral arrange the outside at the pipe wall. Adopt the helical shape to level the wall and makes the bellows axial obtain to support, improved the axial structural strength of bellows on the one hand, reduce the deflection that the inside and outside pressure differential of bellows leads to, the trend of bellows is convenient for arrange by on the other hand, and the two is held concurrently. The utility model also discloses an adopt the oil pipe that adds of bellows, improved the intensity that adds oil pipe on the whole, reduced the deflection that inside and outside pressure differential leads to.

Side.
The semi-ring ripple of tube wall both sides is arranged symmetrically.
The semi-ring ripple of tube wall both sides is staggeredly arranged, the semi-ring ripple of wherein side be in two semi-ring ripples of opposite side it
Between section on.
The section of described tube wall is ellipse, and the short axle of pipe wall internal diameters is d1, and major axis is d2, and the section of semi-ring ripple is ellipse
Circle, short axle is d1, and major axis is d2.
As preferred d1 >=d2≤d1≤d2.
The section of described tube wall is ellipse, and the short axle of pipe wall internal diameters is d1, and major axis is d2, and the section of semi-ring ripple includes
Arc section and the straightway being symmetricly set on arc section two ends, straightway is tangent with tube wall or intersects, and the radius of arc section is
r.
The section of described tube wall includes symmetrical arc section, is symmetrical straightway between arc section, the radius of arc section
For r, the section of semi-ring ripple is ellipse, and short axle is d1, and major axis is d2.
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 bellows, described oil filling pipe includes the hard tube for connecting oil filler and is used for arranging
The bellows of pipeline trend.
The utility model compared with prior art, has the advantage that
Using spiral flat wall, bellows is axially obtained to support, on the one hand improve the knot of the axial direction of bellows
Structure intensity, reduces the deflection that bellows pressure differential leads to, and is on the other hand easy to arrange the trend of bellows, the two gets both.Adopt
With the oil filling pipe of bellows, improve the intensity of oil filling pipe on the whole, reduce the deflection that external and internal pressure difference leads to, meet whole
Car performance requirement.
