Background technique
In modern vehicle suspension design, adopt in a large number rubber bushing etc. to flexibly connect the needs that meet Vehicle damper noise reduction, and obtain needed suspension kinematical characteristic.The effect of automobile absorber is the vibrations of facing vehicle with cushioning, ensure stationarity and the travelling comfort of Vehicle Driving Cycle, wherein important parts of shock absorbing bushing groupware type, the effect of shock absorbing bushing assembly is to connect automotive body and vibration damper, external force is played to buffer function simultaneously, shock absorbing bushing assembly comprises that lining inner tube and the compacting of vulcanized rubber body form, vulcanized rubber bar is bonded in the outer wall of lining inner tube by rubber bond, utilize screw rod to pass the endoporus of lining inner tube, fastening nut, realizes being connected of vibration damper and vehicle body.
Existing lining inner tube mostly is straight tube-like, as patent announcement CN202728311U discloses a kind of automobile bushing, by setting up colored tooth in lining one end, can promote the friction factor of itself and attachment face, makes to connect more reliable.But the join strength of the vulcanized rubber of this lining and lining outer wall of inner tube is the bond properties that rubber bond is sticky, therefore the pull-out strength of the relative vulcanized rubber of lining inner tube is lower.Patent announcement CN103028626A discloses the manufacturing process of oval lining, adopts multi-position cold extrusion shaped, and making to produce the lining inner tube that amount of deformation is larger becomes possibility.As patent announcement CN103727158A discloses a kind of automobile hanging pull bar lining, its outer wall by core retainer plate (lining inner tube) is arranged to convex, to rubber sleeve limited location binding function, can effectively improve its wear-resisting property and fatigue resistance along axial direction.Lining inner tube quality is detected and comprises pressing and become test, load setting pressure at lining two ends, then measure the length deformation of lining inner tube, conventionally require its amount of deformation to be less than 0.1mm, and that the pressure of existing special-shaped lining becomes the up-to-standard rate that test detects is all lower.
Summary of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of new automobile shock absorbing bushing inner tube, and it has higher wear-resisting property and fatigue resistance, improves to press to become the up-to-standard rate that test detects simultaneously.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of automobile shock lining inner tube, comprise the pipe shaft body of straight tube-like, pipe shaft body interior is provided with the endoporus that connects two ends, on the cylinder at described pipe shaft body two ends, form ring-type convex shoulder, on the end face at pipe shaft body two ends, form into the some colored tooth that even circumferential distributes, the external diameter of described colored tooth equates with the external diameter of pipe shaft body.
Wherein, between described ring-type convex shoulder and described pipe shaft body, be provided with circular arc lead angle.The two ends of described pipe shaft body are provided with the hole, rank with the coaxial setting of described endoporus, and the diameter in hole, rank is greater than the diameter of endoporus.Described in two, described in ring-type convex shoulder and two, hole, rank is arranged at the two ends of described pipe shaft body symmetrically.The length of described pipe shaft body is 54mm, and the external diameter of pipe shaft body is 22mm, and the diameter of described endoporus is 12mm, and the diameter in hole, described rank is 13mm, and the external diameter of described colored tooth is 22mm, and the external diameter of described ring-type convex shoulder is 27mm.
Adopt after technique scheme, the advantage that compared to the prior art the utility model had is:
On the cylinder at pipe shaft body of the present utility model two ends, form ring-type convex shoulder, on the end face at pipe shaft body two ends, form colored tooth, the external diameter of flower tooth equates with the external diameter of pipe shaft body, flower tooth can promote the friction factor of itself and attachment face, by ring-type convex shoulder, rubber sleeve is carried out to spacing constraint, effectively improve its wear-resisting property and fatigue resistance, the colored gear division at two ends is passed to institute's applied pressure of pressing change test the body pipe shaft of straight tube-like, can put forward the compression resistance that high voltage variable test detects, increase conforming product rate.
