The specific embodiment
Adaptor union according to the present invention comprises the cover that central thickened partial sum reinforcement two ends provide, and front end and tail end that this cover is suitable for winding steel wire insert.Cover can by the column two ends to its central fovea so that therein the heart define reinforcement and form as dividing plate.
Can form by column or the pipe fitting that cutting or extrusion metal such as iron, copper or aluminium are made according to adaptor union of the present invention.Perhaps, adaptor union forms with resin is integrally moulded.
Form recessed cover by pushing this element with drift from metal cylinder or tube-like piece two ends, cover is extruded to the degree higher than the centre, so that cover is than centre hardness height.Therefore cover can keep enough intensity with the thickness of minimum.This makes again to overlap from the radially protrusion of winding steel wire when the front end of winding steel wire and tail end insertion cover and is reduced to minimum, thereby the end outer surface of cover is reduced gradually.Therefore there is a reinforcement to be made cheaply as the adaptor union of retainer at core as dividing plate or tubulose reinforcement.
The flexure stress that acts on adaptor union and the diameter d of winding steel wire square are directly proportional.If but the diameter of the axial length l of central thickened part and winding steel wire is approximately equal, adaptor union will never crooked or damage.On the contrary, if the axial length l of central thickened part is oversize, adaptor union can not and be put with winding steel wire so, because winding steel wire is wrapped on the toroidal core spirally.Therefore, the axial length of central thickened part preferably is no more than 8 times of winding steel wire diameter.
Especially, the axial length l and the spiral wire diameter d of central thickened part preferably meet relational expression:
The diameter d of winding steel wire≤axial length l≤8 * winding steel wire diameter d
When if the front end of winding steel wire and tail end insert in the cover and the adaptor union reinforcement against and without any the gap, prevent that adaptor union from moving is possible.
But, for this purpose, be difficult because the distance of blocking between winding steel wire front end and tail end equals the axial length of reinforcement just, winding steel wire is blocked length and is preferably between front end and tail end short a little apart from the axial length than reinforcement.Utilize this configuration, insert in the cover by front end and tail end simply, the front end of winding steel wire and tail end seamlessly are pressed on the adaptor union central thickened part winding steel wire.
If but between the front end of winding steel wire and tail end to block length too short, winding steel wire is local easily throws off from toroidal core, thereby tyre performance is caused adverse effect.
Therefore, before winding steel wire front end and tail end inserted cover, winding steel wire was blocked length and is preferably between its front end and tail end distance and equals or be shorter than the reinforcement axial length, and the difference between the two is between the 0-1.1% of the perimeter of a circle that is limited by toroidal core.
Utilize this configuration, because the front end of winding steel wire and tail end can insert in the cover under without any the state in gap at itself and reinforcement, act on the winding steel wire that the flexure stress on the adaptor union partly is inserted in the cover and bear, this has improved the anti-damage of adaptor union.
For reducing weight, the central thickened part can be formed with through hole.
Can make axially extended groove at the cover inside face, rubber flows in the groove when being made by sulfuration with convenient wheel, thereby the winding steel wire of adaptor union and bead cord is firmly bondd.Increased the durability of tire like this.
Preferably, the inside face of each cover is local or whole tapered, and its internal diameter inwardly reduces.Utilize this configuration, because the diameter of the opening of each cover increases, the front end of winding steel wire and tail end can insert in the cover easily.
And, because winding steel wire is spiral and the cone-shaped inner surface guiding of quilt cover glossily, until its end and reinforcement against, winding steel wire will can not be stuck.Therefore, the end of winding steel wire can be easy to link together.
By good balance is arranged on weight with the front end of above-mentioned adaptor union connection winding steel wire and the bead cord that tail end is made, its winding steel wire is unlikely loosening in the end, the wheel that such bead cord is housed in its bead can keep for a long time it performance.
